Description

FIELD OF TECHNOLOGY

This technical solution relates to methods and systems for electronic exchange of goods.

BACKGROUND

Currently, the exchange of goods is quite widespread on the Internet. There are various forums, including thematic forums, where users exchange goods among themselves, in particular, with each other. In the particular case, users can cooperate so that more than two people can participate in the exchange. If there are only two users, for example, one user has a mobile phone that he wants to exchange for an iron, and the second user has an iron that he wants to exchange for a mobile phone, then these two users can usually agree among themselves (in particular if both users are satisfied with the terms of exchange, characteristics of goods, etc.). So, for example, if one user has a microwave oven that he wants to exchange for another product, the second user has an iron that he wants to exchange for another product, and the third user has a mobile phone that he wants to exchange for another product. Let's say one user wants to exchange his microwave for a mobile phone. Another user wants to exchange their iron for a microwave. And the third user wants to exchange their mobile phone for an iron. Thus, it turns out that one user has a microwave, which he wants to exchange for a mobile phone, but a user who has a mobile phone does not need a microwave, but needs an iron, which is another user who does not need a mobile phone, but you need a microwave, which is the first user, but who does not need an iron. So, the second user must give his iron to a third user in exchange for a mobile phone, which he will give to the first user for the desired microwave. To carry out the exchange, these three users must find each other in some way (which is quite difficult, in particular, since the exchange goals and exchange products are different for users, users can post ads in different sections of forums, on different websites, web pages etc.), and agree among themselves on a multi-stage exchange of goods so that each user receives what he wants. If the number of users exceeds three, and therefore the number of intermediate exchanges (for example, when the second user exchanges with the third user to exchange the received goods from the third user for the goods of the first user) between users increases, which makes it more difficult to find each other's users for exchange your product to another product. It is also worth noting that when making an exchange, for example, even if the products desired by the users correspond to the exchanged products of the users, at least one of the users can evaluate their product more expensively than the goods of another user. For example, one user has a mobile phone that he wants to exchange for an iron, and the second user has an iron that he wants to exchange for a mobile phone, and the first user believes that his mobile phone costs 10,000 rubles, and believes that the second user's iron costs no more than 9.000 rubles (in, in the particular case, the second user evaluates his goods exactly in that amount and, in particular, agrees with the first user), so the first user does not agree to exchange with the second user, or n in exchange for a fee of 1,000 rubles from the second user. If the second user does not agree to the exchange with a surcharge, then (most likely) the exchange between these two users will not take place (if the first user does not refuse the surcharge or if the second user does not agree to the surcharge). In order for such an exchange to take place, at least one other user who is also ready to exchange his product for another product can participate in the exchange between the first and second user. Also, at least one user can (say, for example, add information on a website, web forum, etc. that he potentially agrees) to reduce the price at which he estimates his goods (the value of his goods) in particular, provide a discount to other users. Thus, the calculation of the estimated cost of goods and the search and comparison of goods that could be exchanged for such goods at discounts between users is extremely difficult, and with the increase in the number of users participating in the exchange of goods (for example, as in the above example, when in the exchange three users participate) the search, comparison of goods and their cost, taking into account the discount, is complicated with each new user participating in the exchange.

The prior art method of providing value exchange via the Internet (see US 8099331, publ. 01/17/2012), in which the subject (person, company) adds the goods to the list of goods on the server, available for exchange in the market, accessible through a computer network ; the subject on the server assigns value to the subject’s goods; the subject on the server searches for a specific set of goods available in the list of goods in accordance with a set of rules; the server controls the behavior of the subject in accordance with a certain set of rules, so that the subject can offer an exchange to another subject if the cost of the goods is greater than or equal to the value of another product, and such a subject can exchange such goods for goods of another subject once and the subject cannot change the cost product as soon as the product has been listed; the entity on the server offers the aggregate of goods to another entity for exchange for another commodity if the total value of the aggregate of goods is greater than or equal to the value of another commodity; the server deletes the list of goods after a certain amount of time; the north reduces the cost of goods by a certain value several times over a certain period of time; another entity on the server lists the totality of goods that will be offered for exchange in various combinations, depending on the value of the goods; another object on the server puts up a counter offer of the exchange triangle (exchange between the three entities) to the entity as a response to the exchange offer from the entity, so that the other entity agrees to provide other goods to the entity in exchange for the entity providing the goods to a third party and a third party provides the goods to a third party to another entity; and the subject on the server lists the offer template so that another subject can populate the offer template.

The prior art method for providing value exchange via the Internet (see US 20100138350, publ. 06/03/2010), which assigns a certain value to the goods of the subject (person, company, etc.); entering the goods in the list of goods available for exchange on the website; structuring the data set associated with the list of goods and a set of rules in the physical database of a computer system; search in the list of goods for the type of goods; and the exchange of one product for another product of another entity on the website in accordance with a set of rules, such that the entity has the opportunity to offer an exchange to another entity if the specified value of the goods is greater than or equal to the value of another product, and the entity may offer another entity to exchange one goods for another product once, so that the subject is not able to change a certain value after the subject has added the goods to the list.

The prior art also known a method and apparatus for distributing objects (see US 20060200403, publ. 07/07/2006), and the method of controlling the exchange of at least one proposed exchange, at least one provider (seller), at least , for one desired object of at least one acceptor (buyer) of the object, where the method includes the following steps: for one provider and for one acceptor create a database for storing information identifying the provider’s object and the object of the acceptor; promotion of the goods to the acceptor by sending him a message with a proposal to exchange the offeror for the proposed goods for the desired object of the acceptor; a response to the message with the offer to exchange the acceptor for access to the acceptor's database to determine whether the acceptor has the required object in its database and to access the provider’s database of objects to determine whether the offeror has the proposed product in his database, and determination of whether the offeror and the acceptor have the desired objects and proposed objects, so that the exchange could be completed, and if not, then the exchange is not carried out.

The prior art also knows a system and method for exchanging collectible objects (see US 20160125496, publ. 05/05/2016), and the method includes connecting users (collectors) to the exchange system, registering new users who are granted access to the described service, and exchanging between objects (items) by users, each user represented by a home page containing collectible items included in the list of collectible items with their names, description, quantity and image, where gender The user can look at his collection profile, which contains everything that the user has, select objects from the list of collectible goods to add to a personal collection profile or delete objects from the collection profile by selecting the corresponding object and selecting the delete button corresponding to this object.

The disadvantages of existing solutions are, at least, the lack of the creation of a server chain of exchange of goods between users.

Thus, there is a need for a method to overcome at least part of such deficiencies or all of these disadvantages.

ESSENCE

The technical result of this is to automate the selection of exchange chains, increase the speed of exchange of goods between users, simplifying the selection of a chain of goods for exchange.

According to one implementation option, a method for electronic exchange of goods is offered that runs on a server and includes the following steps: receive information from a user about a product for exchange, including at least a product name, product category, product subcategory, product tags, product price , “Plug” prices, categories of goods for exchange of interest, the user's geolocation; search for possible goods for exchange, taking into account the cost, product category, product subcategory, tags, geo-location to add at least one exchange chain when forming at least one exchange chain as a link in the exchange chain and sort the goods found, at least in descending order of value; in response to the availability of goods that meet these search criteria, at least one chain of exchange of goods is formed, and when searching for goods to exchange and at least one chain of exchange of goods is carried out: check whether at least one is found goods for exchange; when the fact of the presence of at least one product found is established, the product found is added to the exchange chain; after adding the found product to the exchange chain, it checks whether the exchange chain length specified by the server has been reached; upon reaching the specified length of the exchange chain, the chain is formed and can be presented to the user, otherwise the search for possible goods for exchange continues; when the fact of the absence of at least one product found is verified, the quantity of the length of the exchange chain is checked; if the length of the exchange chain is greater than one, then the exchange chain is formed and can be presented to the user; if the length of the exchange chain is less than one, then the exchange chain is not formed and cannot be presented to the user; Presentation of at least one link in the exchange chain of at least one exchange chain to at least one user; exchange of goods between users within the same exchange chain.

In one particular embodiment, when the server searches for possible goods and forms the exchange link for the goods by the server, if the type of exchange is Swap to Profit, the goods are searched by the server using the following condition: price Min1 ≤ price Min2 ≤ price Max1 and city = City [and category1 ∈ desiredCategories2 and Tags1 ∩ DesiredTags2], where the priceMin1 is the minimum price of the previous link; price Max1 - the maximum price of the previous link; price Min2 - the minimum price of the desired product; City - a settlement selected on the service; category1 - category of the previous link; Desired Categories 2 - (desired) categories of the desired link; Tags1 - tags of the previous link; Desired Tags2 - (desired) tags of the desired link; ∈ is the entry function; ∩ is the intersection function.

In one particular implementation, when the server searches for possible goods for exchange and the server forms the exchange link, if the type of exchange is Swap to Target, the goods are searched by the server using the following condition: price Min1 ≤ price Min2 ≤ price Max1 and city = City [and category1 ∈ DesiredCategories2 and category2 ∈ DesiredCategories1 and Tags1 ∩ DesiredTags2 and Tags2 ∩ DesiredTags1], where price Min1 is the minimum price of the previous link; price Max1 - the maximum price of the previous link; price Min2 - the minimum price of the desired product; City - a settlement selected on the service; category1 - category of the previous link; category2 - category of the desired link; Desired Categories 1 - (desired) categories of the previous link; Desired Categories 2 - (desired) categories of the desired link; Tags1 - product tags of the previous link; Tags2 - product tags of the desired link; Desired Tags1 - (desired) tags of the previous link; Desired Tags2 - (desired) tags of the desired link; ∈ is the entry function; ∩ is the intersection function.

In one of the private implementations, tags are generated automatically by the server using analysis of the description of the goods and / or analysis of photographs of the goods.

In one of the private options for implementation, photos of goods are added by the server automatically based on the analysis of the description of goods from the database of photographs and / or the Internet.

In one of the private embodiments, the description and / or tags of the goods are generated by the server based on the analysis of the photographs of the goods.

In one of the private options for implementation, the user selects at least one product for which he wants to exchange his product, and / or selects at least one category of goods and optionally at least one subcategory of goods to which refers to a product exchanged by the user or to which at least one product relates to which the user is willing to exchange his product.

In one of the private embodiments, upon successful formation of the exchange chain, at least one user is sent an alert with an offer about the exchange.

In one particular implementation, when a user refuses to exchange a server, the link associated with the product of the user who refused the exchange is replaced, and the server selects at least one new link in the exchange chain by searching for goods for exchange and adds at least at least one new link in the exchange chain to the exchange chain.

In one of the private options for implementation, the user on the server confirms the exchange of goods in the real world, and if the user has more than two goods for exchange, the next such goods for exchange can be added by the user to the server for exchange, optionally without changing the photos of the goods, the description of the goods, tags, categories and subcategories of products.

DETAILED DESCRIPTION

Objects and features of the present technical solution, methods for achieving these objects and features will become apparent by reference to exemplary embodiments. However, the present technical solution is not limited to the exemplary embodiments disclosed below, it can be embodied in various forms. The essence described in the description is nothing more than the specific details provided to assist the specialist in the field of technology in a comprehensive understanding of the technical solution, and the present technical solution is determined only in the scope of the attached formula.

Used in the present description of the technical solution, the terms “module”, “component”, “element” and the like are used to refer to computer entities, which may be hardware / equipment (for example, a device, instrument, apparatus, apparatus, component of a device, for example, processor, microprocessor, integrated circuit, printed circuit board, including electronic printed circuit board, breadboard, motherboard, etc., microcomputer, and so on), software (for example p, executable program code, compiled applications, a software module or a piece of software code, and so forth), and / or firmware (eg, firmware). So, for example, a component can be a process running on a processor (s), an object, executable code, program code, file, program / application, function, method, (software) library, subprogram, coroutine and / or computing device (for example, microcomputer or computer) or a combination of software or hardware components. So, in the particular case, the application running on the server 110 or the computing device ( 120A-120N ) can be a component / module, while the server 110 or the computing device ( 120A-120N ), in turn, can be a component (module). It is worth noting that at least one component (module) can be part of the process. A component (module) can be located on one computing device (for example, a microcomputer, microprocessor, printed circuit board, etc.) and / or can be distributed / shared between several computing devices.

The described method allows the selection of goods for exchange between users, both between two and between multiple users, by forming chains of exchange of goods (hereinafter chain), in particular, based on the value of the goods, desires and preferences of users.

Users through a website displayed on a computing device (WU), for example, on computing devices ( 120A-120N) or through an application (including a mobile application) installed on computing devices ( 120A-120N) , are registered on the server 110 with the purpose of exchanging goods with each other. When registering, users indicate their contact details, name, place of residence, in particular the city (village, village, village, etc.), street, nearest metro station, if any, etc. In the particular case, the user of VU 120A (user 1) can exchange his goods for the goods of another user, for example, user VU 120B (user 2) or user VU 120B (user 3) and so on up to user VU 120N (user N).

A computing device ( 120A-120N ) can be a mobile phone, smartphone, tablet, personal computer, laptop, etc.

Users through the website or application add the goods they want to exchange. When adding goods, users can specify the name, description and estimated value of their goods (price of their goods, price of goods). It is worth noting that the estimated value (price of the product) is the value of the product added by the user according to the user.

The user also assigns a price range (“plug”) through a website or application, which in a particular case is a discount that the user is ready to provide for the added product. The size of the discount can vary within various limits and range from 0 to 99 percent of the estimated value of the added product. The user can set a price range, for example, using at least one element of a graphical user interface on a website, in a (mobile) application, etc.

When adding goods, the user can select the category to which the goods added by him belong. Categories of added goods may include automobiles, phones and tablets, real estate, photos and videos, computer equipment, electronics, household appliances, health and beauty, sports and leisure, women's clothing, men's clothing, children's clothing, children's goods, animals, repair and construction , house and cottage, etc. The number of categories is not limited and can be added (changed). Adding can be done by an administrator, a user with authority to add, or other categories of users.

Also, when adding goods, the user can select a subcategory of the selected category. So, for example, for the transport category, subcategories may include cars, motorcycles and motorcycles, trucks and special equipment, water transport, spare parts, etc., etc. For example, for the category house and cottage, subcategories from which the user adding the product can choose, may be subcategories of household appliances, furniture and interior, dishes and kitchen goods, food, repair and construction, plants, etc., etc. Also, the user can add an image of the product for added to exchange goods.

After confirming the addition of the product, the above-mentioned user-entered data is added to the data warehouse database 130 of the server 110 .

In some embodiments, the user can hide (in particular, exclude) the goods from participating in the exchange until the moment they begin to use the exchange.

In some implementations, said data storage may include, but is not limited to, networked storage, cloud storage, hard disk drives, floppy disk drives, etc.

The data warehouse 130 may be at least one hard disk drive (HDD), a solid state drive (from the English solid-state drive / SSD), a storage network (SAN, from the English Storage Area Network), a network system data storage (NAS, from the English Network Attached Storage) and / or any other device that allows you to record, read and / or store data on a device that implements data storage. It is also worth noting that the data in the mentioned data warehouses can be stored in any known format, for example, in the form of a database (DB), for example, in the form of tables. Also, at least one of the mentioned databases can be hierarchical, object, object-oriented, object-relational, relational, centralized, fragmented / partitioned, replicated, spatial, etc., moreover, for managing, creating and using databases various database management systems may be used.

Also, when adding a product, the user can assign a product (future link in the chain) at least one tag (from English, tag - label, label, tag, label - identifier for categorization, data search, etc.) for the product, in particular characterizing the product or at least one quality of the product, etc. The user can assign a tag (product) by writing a tag that will be assigned to the product by the server110 and can be added to the data warehouse database130. The user can also assign a tag by, for example, selecting tags from a data warehouse database130, eg, using elements of the graphical user interface (for example, using a list, drop-down menu, etc. of the available tags stored in the database), and the tags can be added to the database by the server administrator (or another authorized user)110. It is worth noting that tags can be assigned to the product by the server.110 automatically, for example, based on the analysis of the product description, image analysis (photographs, drawings, etc.) of the product. In some implementations, tags can be assigned to a product using a tag reference (in particular, a hashtag reference) and / or tagging services, in particular hashtags, for example, the hashtagify service can be used (see https://hashtagify.me / manual / api). So, for example, when the user enters the description of the goods (or at any other time, for example, after entering the description of the goods, including before or after the exchange of goods), the server110 can analyze the content of the product description entered by the user, for example, parts of words, words, phrases, sentences, etc., and automatically generate (create) tags for such a description (for the user's product). Server110 assigns tags to such a product, and tags can be created by the server using a tag generator (for example, tag generators (IMSmartyTag, Auto Tag Generator, etc.), and an analysis of the content of the product description entered (or entered) by the user can be implemented by the server using, for example, using Natural Language Processing (NLP) technology.

It is worth noting that in a particular case, the user can add at least one photo of the product, in particular without a description of the product, and / or an indication of the category of the product, and / or subcategory of the product, etc.

In some embodiments, the server 110 can analyze the photograph of the product and add a description and / or modify the description for the product and / or parameters (characteristics) of the product and / or product tags and / or product categories and / or product subcategories and other product information.

In some implementations, said analysis of at least one image added by a user can be performed using machine learning algorithms and databases, for example, images, in particular, using the APIs provided by them, examples of which are given in the present description.

When analyzing a product photo added by a user, server 110 can compare the added photo and photos stored in accessible databases, for example, in a data warehouse 130 , on the Internet, etc., including, but not limited to, social networks, image stores , services that provide services for the sale and purchase of goods, etc., and such accessible images may be accompanied by text related to this image. Such text relating to an accessible image can be used by server 110 to create or modify for an added product: tags, descriptions, categories, subcategories, etc. It should be noted that the text related to the image may be: image tags; meta-information contained in the image file, for example, name, date and place of creation of the image, etc .; text of an article containing an accessible image, etc.

In some implementations, a google cloud vision api service (https://cloud.google.com/vision/), clarifai (https://www.clarifai.com) or the like can be used to analyze the added photo. Services can be accessed using the API or other methods available for this service. The type of access does not affect the essence of the technical solution.

In some implementations, after determining what is in the photo, server 110 searches for products with such a description on available trading floors (for example, Yandex.market, Amazon, etc.) and adjusts the description of the product and price in accordance with the information found on the sites .

It is also worth noting that if the user did not add a photo of the product when adding goods for exchange, the server 110 can analyze the description of the goods and / or category of goods, and / or subcategory of the goods, i.e., in the particular case, all or part available data (information) for the product, find and add an image for such a product from available images, for example, in the database of the data warehouse 130 , from the Internet, including, but not limited to, social networks, image stores, services providing sales services and n Kupka goods, etc.

So, for example, if a product description is added: a Nikon D5300 camera, camera category, SLR camera subcategory, then server 110 can turn to trading floors (for example, Yandex.market, Amazon, etc.) or other services, search, find such goods , save the corresponding photo and description (https://tech.yandex.ru/market/content-data/doc/dg-v2/reference/models-controller-v2-get-matched-models-docpage/).

 In order to exchange their goods, the first user (the initiator of the exchange) can choose the final purpose of the exchange, which is the goods of another user, in particular, by indicating on the website or application the desired exchange of goods from goods added by other users.

If the cost (price) of the goods of the first user, taking into account the price range of the goods, is equal to the value of the selected goods of another user, taking into account the price range for such goods (i.e., the prices of goods intersect within the price forks), then the server 110 creates an exchange chain. So, for example, the price range (“fork” of the price) for a smartphone added by the user for exchange can be 10 percent of the smartphone value that the user assigns to his smartphone when adding a smartphone for exchange. Thus, for the price range (“plug” price) of 10 percent for a smartphone added by the user for 10,000 rubles for the exchange, the price range (“plug” price) in rubles will be 1,000 rubles, so other goods can be exchanged for this product, whose price (taking into account the “fork” of prices) ranges from 9.000 rubles to 10.000 rubles. For example, a user can indicate that he is ready to exchange a tablet for 20,000 rubles, and is ready to make a discount of 20% of its indicated value if the exchange takes place today. Or the user is ready to exchange (make an exchange) for 16,000 rubles, but only today, and on the remaining days, the price of his product (in particular, the tablet) is 20,000 rubles.

Moreover, this particular case of the exchange chain includes only one exchange of goods between the first user and the second user.

If the cost (price) of the goods of the first user, taking into account the “fork”, the price of the goods is not equal to the value of the goods of the other user selected by the user, taking into account the “fork”, prices for such goods (that is, the prices of goods do not intersect within the price forks), then server 110 an exchange chain is being created, in particular, through the selection of goods whose exchange with the goods of one user and the goods of another user will lead to the desired exchange of goods of one user for goods of another user. So, for example, if user 1 added an “A” smartphone for exchanging for 10,000 rubles and set a “plug” price of 5 percent (500 rubles), and user 2 added a “B” smartphone for exchanging for 9.000 rubles and set a “plug »Prices equal to 10 percent (900 rubles). Thus, the smartphone of company “B” cannot be exchanged for the smartphone of company “A”, since the minimum exchange price for a smartphone of company “A” is 10.000 rubles minus 500 rubles, i.e. 9.500 rubles, and the maximum price of measuring the smartphone of the company “B” is 9.000 rubles, so server 110 will continue to search for products with a price in the range, in this case, from 9.500 rubles to 10.000 rubles, taking into account (“plugs” of the price) for exchange to a smartphone company "A". However, if user 1 sets (or changes) the price range (“plug”) of the price for his “A” smartphone by 10 percent, then the “B” smartphone can be exchanged for a “A” smartphone, since the minimum exchange price for the smartphone company A is 10,000 rubles minus 1,000 rubles, i.e. 9.000 rubles, and the maximum price for measuring the smartphone of the company "B" is 9.000 rubles. The price range (“fork” of the price) is a tool (method) for regulating the threshold for reducing the price of goods added for exchange, which, in the particular case, allows you to increase the number of offers for the exchange of goods (in particular, the number of chains and / or exchange goals) to the user or benefit when exchanging goods. For example, a user has a laptop for 30,000 rubles, which he wants to exchange for any product at the same price. Without a “plug”, he will not be able to consider (he will not be provided, in particular, found) goods for 28,000 rubles, for 25 000 rubles, etc .. By adding a “plug” price of 20%, his minimum price for a laptop, which he is ready to consider, drops to 24 000 rubles. Within the price range from 24 000 to 30 000, more goods are exchanged and higher chance to make an exchange. In some embodiments, for selecting at least one ultimate goal of exchanging goods to the first user, server 110 implements the formation of an exchange chain and selection of goods of other users, in particular, which, due to the “fork”, are a profitable offer for the first user (Swap type to Profit ") in order to obtain an arbitrary target product by the user with the maximum price. It is worth noting that the benefit for the “Swap to Profit” type of exchange for one user is achieved due to the “forks” of prices offered by other users and the algorithm that each subsequent link in the chain selects at the highest price.

It is also worth noting that users can have several types (roles), for example, the type of user who makes, in particular, one-time (direct) exchanges of one product for another product (Swapper, from the English Swapper), or the type of user who makes the exchange of goods , in particular, for the sake of exchange, to achieve an arbitrary or specific goal (Fraser, from the English Phraser). The user can select one of the user types by means of graphical user interface elements on a website, in a (mobile) application, etc. So, for example, for the Swap to Profit type of exchange, the number of links in the exchange chain can be, for example, up to eight links from Fraser, and this restriction may be due to a limitation in computing power (in particular, server 110 ) and in time to achieve the result ( in particular, the search for goods and the formation of chains of exchange of goods).

In some implementations, when selecting the final goal, the server 110 may not take into account the categories of goods participating in the exchange, and also may not take into account the price plug specified by users (Swap to Random exchange type), i.e. in the particular case, the server 110 creates chains of exchange with a benefit exceeding the maximum value of the “fork” of the price for at least one user (for example, the initiator of the exchange), in particular by adding random links to the chain of exchange.

In some implementations for a particular type of exchange (for example, Swap to Target, Swap to Profit, etc.), the number of exchange chains that server 110 forms can be limited to a certain number n, which can be set to reduce the load on server 110 .

In some embodiments, the user can also select the categories (desired categories) for goods in which the user wishes to exchange his goods, i.e. in which the server 110 will search for goods and sample products (as described below) for exchange. So for your product, for example, a mobile phone (in particular, a smartphone), added for exchange, the user can select (set, set) a category (as well as a subcategory) corresponding to the category to which the user's product belongs, in particular, the category "phones and tablets, "and the user can also select at least one category, products of other users from which he is interested and for goods from which the user agrees to exchange at least one of his goods (mobile phone a) added to the exchange. So, for example, the user can choose the category for which goods he agrees to exchange, for example, the user can choose the category "electronics" and / or "computer equipment", and / or "household appliances", etc.

At the beginning of the exchange, the user can indicate at least one desired category and / or subcategory of goods whose goods will be used to create exchange chains.

As mentioned above, the exchange of goods added by the user to the final purpose of the exchange may include intermediate exchanges of some goods for other goods (type of exchange “Swap to Target”). So, for example, to exchange added goods by user 1 VU 120A for added goods by user N VU 120N , an intermediate exchange of added goods by user 1 VU 120A for added goods by user 2 VU 120B can be carried out, as well as exchange of added goods by user 2 VU 120B for added goods by the user 3 WU 120B and so on until the exchange of the added goods by the user N-1 WU 120N-1 for the added goods by the user N WU 120N , which is the ultimate goal of the exchange of goods for the user 1 WU 120A . So, for example, user 1 added a microwave oven for exchange (he chose the category “household appliances” and the subcategory “small kitchen appliances” for his product and selected the category, and in particular the subcategory, for the goods from which he agrees to exchange his microwave oven, for example, I chose the category “phones and tablets” and the subcategory “mobile phones”) and set the price (price of the goods) for it at 1,000 rubles with a 10% plug (900 rubles - 1,000 rubles). User 3 added a mobile phone for exchange (he chose the category “phones and tablets” for his product and the subcategory “mobile phones” and selected a category, and in particular, a subcategory, for the goods from which he agrees to exchange his mobile phone, for example, chose a category “Household appliances” and the subcategory “small household appliances”) of 3,000 rubles with a 10% plug (2,700 rubles - 1,000 rubles). Directly (without “intermediaries”, intermediate links), user 1 and user 3 cannot make an exchange, since the cost (including the “plug” of the price) of the mobile phone of user 2 is higher than the cost (including the “plug” of the price) of the microwave oven of user 1. However, user 2 added an iron for the exchange (he chose the category “household appliances” for his product and the “small household appliances” subcategory and selected a category, and in particular, a subcategory for which he agreed to exchange his microwave oven for products, for example, chose a category “Household appliances” and the subcategory “small kitchen appliances”, and also chose the category “phones and tablets” and the subcategory “mobile phones”) and set the price for it at 2,600 rubles with a “plug” price of 75% (650 rubles - 2,600 rubles ) Thus, the user 3 server 110 may be asked to exchange the mobile phone for the iron of user 2. Also, the user 2 server 110 may be offered the exchange of iron for the mobile phone of user 3 or the microwave oven of user 1. Also, user 1 server 110 may be offered exchange of the microwave oven to the mobile phone of user 1 or to the iron of user 2. If user 2 selects the microwave and user 1 selects the mobile phone, then user 3 will receive the iron in the process of Names the user 2, user 2 will first receive a mobile phone, which will be exchanged microwave User 1.

It should be noted that the exchange of one product of one user for another product of another user is a chain of exchange of goods (goods), and the goods are links in such a chain, and such exchange may include an intermediate exchange of goods (or several exchanges of goods).

Server 110 , the formation (creation) of at least one chain of exchange of goods ("Chain" in FIG. 2 ) is carried out after the user selects the final exchange target (goods of another user) or when selecting at least one target of exchange of goods to the user .

The chain formed by the server 110 is displayed to at least one user participating in the exchange, and intermediate exchanges of goods (and links of the exchange chain) are displayed, if any, exist within the chains, in particular, the goods (and users) participating in such an exchange (for example, between user 1 WU 120A and user N 120N ) and added for user exchange.

It is also worth noting that the exchange of one product of one user for another product of another user without an intermediate exchange is a particular case of the chain, and at least the purpose of the exchange (the product of the last user of the exchange chain) is a link in the exchange chain, in particular with respect to the initiator exchange, and the goods of the initiator of the exchange is also a link in the chain, in particular, in relation to the end user.

Thus, one product, including the goods of the intermediate exchange of goods (goods), within the same chain is a link in such a chain. For example, in the above example, the exchange of goods of user 1 VU 120A for goods of user N VU 120N with intermediate exchanges of goods - the goods of user 1 VU 120A , exchanged for goods of user 2 VU 120B , is a link in the chain (“Link 1” in FIG. 2 ) . In the above example, the product of user 2 VU 120B exchanged for the product of user 3 VU 120B is a link in the chain (“Link 2” in FIG. 2 ) and so on, and the product of user N (the last user in the exchange chain) is a link in the chain (“ Link N "in FIG. 2 ). In the particular case, with respect to the first user (user 1), the product of user 1 is not a link in the chain and cannot be deleted by the server 110 when selecting a new link for the exchange chain, as described below, since user 1 is the initiator of the exchange.

As mentioned above, the exchange of one product for another can be carried out without intermediate exchanges, “directly” between two users (type of exchange “Swap to Swap”), for example, the exchange of goods of user 1 WU 120A for goods of user N 120N or exchange of goods of user 1 VU 120A for the goods of the user 3 VU 120V .

After the server 110 forms chains and displays them to the user by the server 110, the user can:

- save the chain;

- delete the chain;

- replace the chain link.

After the server 110 forms chains, the server 110 can also offer an exchange, for example, by sending such users notifications, messages and / or by displaying the exchange offer on a website, (mobile) application, etc., in particular, where users exchange goods.

Also, after the server 110 forms at least one chain, the user who initiates the search (and exchange of goods) whose goods belong to the exchange chain can see (in particular, open) each link in the chain (with the display in the form of a product card) for View data entered by users whose products belong to such an exchange chain. Other users (participants in the exchange chain) can receive offers for the exchange of their goods to the previous link in the exchange chain from the user initiating the search (exchange). In a particular case, the participants in the chain links do not know anything about the real owners of the goods in the exchange chain. Since all exchanges with each link in the exchange chain, the exchange initiator performs sequentially from the second link to the last, the first link being the goods of the user initiating the exchange. Mentioned data entered by users may include, for example, a description of the product, photos of the product, information about the user who added the product, and other information, in particular, the user entered during registration, adding products or any other information, in particular, entered or changed later .

After the formation of at least one chain to users participating in the exchange of goods within one such chain, the links of the formed chain are displayed, for example, on a website, in a (mobile) application, etc. Further, each of the users of one such chain can confirm consent to the exchange within one of the formed chains, i.e. select one of the formed chains and confirm the exchange of your product for the final purpose of the exchange (the goods of the last user in the chain), including confirm the participation of your product in intermediate exchanges of goods (which are links in the chain), if any, take place in the chain. It is worth noting that the user can confirm his consent to the exchange of goods by interacting with graphic controls (for example, through a soft button, widget, etc.) placed on a website, in a (mobile) application, etc.

After obtaining consent for the exchange of goods from at least one user, the server 110 transmits at least one notification to the user of the chain initiating the exchange about the consent of the other user to the exchange (readiness of such user for exchange). After the server 110 receives confirmation of the exchange of goods from at least one user (for example, a second user) other than the user (first user) who sent the confirmation of the exchange of goods, the user initiating the exchange can be notified about the possibility of exchanging goods without additional approval of the exchange or with additional approval of the exchange. It is worth noting that additional coordination of the exchange may include a discussion of additional terms of exchange, the possibility of obtaining discounts, conditions for the transfer of goods, etc. one of the users. Additional coordination can be carried out between users participating in the exchange (within the same chain and / or one link in the chain), for example, via computer network messaging tools (chats, chatters, chatting from the English), instant messaging systems (messenger , from the English messenger - courier), SMS (from the English Short Message Service - “short message service”) displayed on users' computing devices, in particular, on a website, (mobile) application, etc. other software that provides text, and / or voice, and / or video communication, in particular, via the Internet between computing devices (user computing devices, server 110 , etc.).

In some embodiments, after one user receives confirmation of an exchange from at least one other user, the exchange chain can be marked, in particular, by server 110 , with different colors, for example, orange, in case additional coordination is required, at least , from one user whose product belongs to such an exchange chain, or, for example, in green, if no additional approval is required. Also, the chain can be marked, for example, in red if at least one user of the chain has withdrawn his confirmation for the exchange (refused to exchange, canceled the confirmation for the exchange), as described below. It is worth noting that in the particular case, the marking of at least one part of the exchange chain, in particular at least one link in the exchange chain, is displayed to the user initiating the exchange.

In the particular case, after users receive confirmation of the exchange of goods from other users, the goods of users who have confirmed the exchange within the chain become inaccessible to exchange for goods (not belonging to such a chain) of other users. In particular, the products of users who have confirmed the exchange (who have agreed to the exchange, who have confirmed their consent to the exchange) are not used to build other exchange chains, in particular, they are not used in search queries performed by the server 110 to the data warehouse database 130 to search for goods that can be offered to users for the exchange and formation (construction) of chains and, in particular, links of chains.

It is worth noting that at any time (before, during or after the creation of at least one chain), at least one user can remove (hide) their goods for exchange.

It is also worth noting that after the user confirms the exchange, such a user can at any time refuse to exchange his product (belonging to the exchange chain). It is worth noting that after refusing to exchange the user, the chain and / or chain link containing the goods for which the user of such goods has canceled (removed, canceled) the confirmation of the exchange can be marked by server 110 , for example, in red.

In case of refusal to exchange (cancellation of confirmation of exchange) by at least one user, at least one link associated with the product of the user who refused to exchange can be marked by server 110 , for example, in red, and the user who is the exchange initiator may decide to replace it, and the user initiating the exchange may delete the exchange chain containing a marked (for example, red) link of the exchange chain. In a particular case, the server 110 can select at least one link instead of at least one of the labeled chain links mentioned.

After the server 110 has successfully selected at least one new replacement link (in particular, the product) to the newly added link (in particular, the product user of such a chain link), a notification is sent with the server 110 requesting an exchange. Also, a notification with an offer to exchange is sent to the neighboring links of the added chain.

So, for example, if a chain link (Link 2, FIG. 2 ) has been replaced by a new link in the chain, for example, “New Link 2”, then a notification is sent to the next link in the chain on one side of “New Link 2” (Link 1, FIG . 2 ) and the next link in the chain on the other side of the “New Link 2” (Link 3, FIG. 2 ), as well as the added link in the “New Link 2” chain (to the product user in the “New Link 2”).

After users of at least two neighboring links of the exchange chain or the entire chain successfully exchanged goods in the real world (for example, when they met, by delivering goods by mail by courier, etc.), i.e. after a physical exchange of goods, all participants (at least two exchange participants) of the exchange (exchange chain) confirm the receipt of goods (in particular, confirm the fact that the exchange took place in the real world) for the goods of the chain, for example, through elements of a graphical user interface on website, in (mobile) application, etc. After confirming receipt of the goods, one of the users starts the program timer on the server 110 (for example, using a graphical user interface element) with a countdown for a predefined time, for example, for 24 hours, two days, etc. Prior to the end of the timer (expiration of the predefined time), the second user of the exchange chain must confirm or deny the fact of exchange. Otherwise (if the second user does not confirm the fact of the exchange of goods), the server 110 performs automatic confirmation of the exchange of goods, which in a particular case protects users from re-registration ("hijacking") of the goods. After the user completes the exchange, the user's product (for which the exchange was completed) can again be offered for exchange (for example, if the user has several units of the product), and the user can not change the description of the product, characteristics, photos, etc. and offer it for exchange as is or may change the description of the product, characteristics, photos, etc. before offering the product for exchange to other users.

Also, after the user completes the exchange, the user's product can be deleted and can no longer be used for exchange.

In some embodiments, the server 110 may be set (for example, by the administrator of the server 110 ) the maximum length of the exchange chain, in particular, the maximum number of links in the exchange chain may be set. In some implementations, the maximum number of links in the chain can be set depending on the type of exchange (Swap to Profit, Swap to Target, etc.). In some implementations, the maximum number of exchange links can be set to infinity, and in the particular case, the chain will be formed while the server 110 will contain goods for exchange that correspond to the parameters (characteristics) of goods used by the search filter.

In FIG. 3 shows a block diagram of an exemplary embodiment of the formation of a chain of exchange of goods. In step 305 , the process of forming an exchange chain by server 110 for multiple exchanges (including more than one link in the exchange chain) to the desired product (Swap to Target) or for multiple exchanges for the user (the initiator of the exchange) to receive an arbitrary product with a maximum price (Swap to Profit) begins .

In step 310, the server 110 receives the goods of the initiator of the exchange, in particular, the parameters (characteristics) of the goods are obtained, including, but not limited to: cost of goods (estimated cost of goods), product categories, tags, location of goods (city and / or country) where the user resides (or is ready to exchange his product).

In step 325, the server 110 searches for goods and selects goods, other users who have added their goods for exchange, to form exchange chains. Search and sampling of goods is carried out using a filter according to the following parameters (of goods): product price, product category, tags, location. Also, in step 325, the server 110, for generating the obtained sample, sorts the received sample of goods according to the estimated value of the goods.

It is worth noting that when searching for goods and forming a selection of goods by server 110 in step 325 , if the type of exchange is “Swap to Profit”, the goods are searched using the following condition: price Min1 ≤ price Min2 ≤ price Max1 and city = City [and category1 ∈ desiredCategories2 and Tags1 ∩ Desired Tags2],

Where

- “price Min1” - the minimum price of the previous link, taking into account the plug (where “1” is the index of the previous link, in particular, is the index of the goods of the previous link);

- “priceMax1” - price of the previous link;

- “price Min2” - the minimum price of the desired product (where “2” is the index of the desired product, in particular, is the index of the desired (in particular, the next) unit);

- “City” - a settlement selected on the service;

- “category1” - the category of the previous link;

- “Desired Categories 2” - (desired) categories of the desired link;

- “Tags1” - tags of the previous link;

- “DesiredTags2” - (desired) tags of the desired link;

- "∈" is the entry function;

- “∩” is the intersection function.

Thus, if the type of exchange is Swap to Profit, the server 110 searches for goods whose minimum price is greater than the minimum price (determined by the minimum value of the “fork” price) and lower than the price of the goods of the previous link in the context of the selected location of the goods (in particular, locality) , in the desired categories of which the category of the previous link is indicated and (desired) tags intersect with the tags of the previous link.

It is worth noting that when searching for goods and forming a selection of goods by server 110 in step 325 , if the type of exchange is Swap to Target, the goods are searched using the following condition: price Min1 ≤ price Min2 ≤ price Max1 and city = City [and category1 ∈ DesiredCategories2 and category2 ∈ DesiredCategories1 and Tags1 ∩ DesiredTags2 and Tags2 ∩ DesiredTags1],

Where

- “price Min1” - the minimum price of the previous link (where “1” is the index of the previous link, in particular, is the index of the goods of the previous link);

- “priceMax1” - price of the previous link;

- “price Min2” - the minimum price of the desired product, in particular (where “2” is the index of the desired product, in particular, is the index of the next link);

 “City” - a settlement selected on the service;

- “category1” - the category of the previous link;

- “category2” - category of the desired link;

- “Desired Categories 1” - (desired) categories of the previous link;

- “Desired Categories 2” - (desired) categories of the desired link;

- “Tags1” - product tags of the previous link;

- “Tags2” - product tags of the desired link;

- “Desired Tags1” - (desired) tags of the previous link;

- “DesiredTags2” - (desired) tags of the desired link;

- "∈" is the entry function;

- “∩” is the intersection function.

Thus, if the type of exchange is “Swap to Target”, server 110 searches for goods whose minimum price is greater than the minimum price and lower than the price of the goods of the previous link in the context of the selected location of the goods (in particular, the settlement), where the wishes of both parties are taken into account ( users, in particular, the characteristics of the goods of the previous link and the desired link.

Next, in step 335, the server 110 checks whether at least one product is found in step 325 , in particular, whether the generated selection contains at least one product. If at least one product was found by server 110 in step 335 , the process proceeds to step 345 , otherwise, proceeds to step 375 .

In step 355, the server 110 checks whether the specified chain length has been reached, in particular, the maximum number of links in the exchange chain, for example, for the type of exchange (Swap to Profit, Swap to Target, etc.). If it is determined by the server 110 in step 355 that the specified chain length has not been reached, then it returns to step 325 , otherwise, it proceeds to step 365 .

In step 375, the server 110 checks the number of links in the exchange chain. If the server 110 determines in step 375 that the number of links in the exchange chain is more than one, then the chain is formed in step 385 and can be presented (displayed) to the user initiating the exchange, and proceeds to step 365 .

If the server 110 determines in step 375 that the links in the exchange chain are less than or equal to one, then the chain is not formed in step 395 and cannot be presented to the user, and proceeds to step 365 .

In step 365, the process of forming a chain of exchange of goods ends.

In FIG. 4 shows a flow diagram of a method according to one embodiment.

In step 415 , information is received from the user about the product for exchange, including at least the name of the product, product category, product subcategory, product tags, product price, “plug” prices, categories of goods for exchange of interest, and the user's geo location.

In step 420 , a search is made for possible goods to be exchanged taking into account the cost, product category, product subcategory, tags, geo-location to add at least one exchange chain when at least one exchange chain is formed as a link in the exchange chain and sorted goods found, at least in descending order of value. When searching for goods for exchange and when forming at least one chain of exchange of goods, the following is carried out: check whether at least one goods for exchange has been found; when the fact of the presence of at least one product found is established, the product found is added to the exchange chain; after adding the found product to the exchange chain, it checks whether the exchange chain length specified by the server has been reached; upon reaching the specified length of the exchange chain, the chain is formed and can be presented to the user, otherwise the search for possible goods for exchange continues; when the fact of the absence of at least one product found is verified, the quantity of the length of the exchange chain is checked; if the length of the exchange chain is greater than one, then the exchange chain is formed and can be presented to the user; if the length of the exchange chain is less than one, then the exchange chain is not formed and cannot be presented to the user. In some implementations, when the server searches for possible goods and forms the exchange link for the goods by the server, if the type of exchange is “Swap to Profit”, the goods are searched by the server using the following condition: price Min1 ≤ price Min2 ≤ price Max1 and city = City [and category1 ∈ desiredCategories2 and Tags1 ∩ DesiredTags2], as described in the framework of this technical solution. In some implementations, when the server searches for possible goods for exchange and the server forms the exchange link for the goods, if the type of exchange is “Swap to Target”, the goods are searched by the server using the following condition: price Min1 ≤ price Min2 ≤ price Max1 and city = City [and category1 ∈ DesiredCategories2 and category2 ∈ DesiredCategories1 and Tags1 ∩ DesiredTags2 and Tags2 ∩ DesiredTags1], as described in the framework of this technical solution. In some implementations, tags are automatically generated by the server using analysis of the description of the goods and / or analysis of photographs of the goods. In some embodiments, product photos are added automatically by the server based on an analysis of the product description from the photo database and / or the Internet. In some implementations, a description and / or product tags are generated by the server based on an analysis of product photos.

Next, in step 425, in response to the availability of goods that meet these search criteria, at least one chain of exchange of goods is formed. In some embodiments, upon successful formation of the exchange chain, at least one user is sent an alert with an offer about the exchange. In some embodiments, the user (the initiator of the exchange) selects at least one product for which he wants to exchange his product, and / or selects at least one product category and optionally at least one subcategory of the product to which the goods exchanged by the user belong, or to which at least one product relates to which the user is ready to exchange his goods. In some embodiments, when the user refuses to exchange the server 110 , the link associated with the product of the user who refused the exchange is replaced, and the server selects at least one new link in the exchange chain by searching for the goods for exchange and adds at least , one new link in the exchange chain to the exchange chain (of goods).

At step 430 , at least one link of the exchange chain of at least one exchange chain is presented to at least one user, in particular the user initiating the exchange, is displayed by the server 110 (in particular, on the website) formed chain (or several) of the exchange of goods.

At step 435 , goods are exchanged between users within the same exchange chain. In some embodiments, the user (who is the initiator of the exchange or who is offered the exchange of goods with the user who is the initiator of the exchange) on the server 110 confirms the exchange of goods in the real world, and if the user has more than two goods for exchange, the next such exchange item can be added by the user to a server for exchange, and optionally without changing product photos, product descriptions, tags, categories and subcategories of goods.

In FIG. 5 shows an example exchange chain for the Swap to Swap (S2S) type of exchange. The price (in particular, at which the user initiating the exchange evaluates his goods) for the 515 bicycle is 8000 rubles, and the minimum price is 5600 rubles. The price (in particular, at which a different user evaluates their goods than the initiator of the exchange) for a mobile device, in particular a smartphone (for example, iPhone 5s 16GB, gold 525 ), is 11250 rubles, and the minimum price is 7875 rubles.

In FIG. 6 shows an example of an exchange chain for the Swap to Target (S2T) exchange type. The price (in particular, at which the user initiating the exchange evaluates his goods) for the 615 bike is 8000 rubles, and the minimum price is 5600 rubles. The price (in particular, at which one of the other users, different from the initiator of the exchange, evaluates their goods) for a mobile device, in particular, a smartphone (for example, Xiaomi mi max 625 ) is 11,400 rubles, and the minimum price is 7,980 rubles. The price (in particular, at which one of the other users, different from the initiator of the exchange, evaluates their goods) for the air solar collector 635 is 16,230 rubles, and the minimum price is 11,361 rubles. The price (in particular, at which one of the other users other than the exchange initiator evaluates their goods) for the power simulator (ST-201 HOME GYM) 645 is 22570 rubles, and the minimum price is 15799 rubles.

In FIG. 7 shows an example of an exchange chain for the Swap to Profit (S2P) exchange type.

The price (in particular, at which the user initiating the exchange evaluates his goods) for the 715 bike is 8000 rubles, and the minimum price is 5600 rubles. The price (in particular, at which one of the other users other than the exchange initiator evaluates their goods) for a portable radio station (YAESU VX-170 / FNB-83 / NC-88) 725 is 11,180 rubles, and the minimum price is 7,826 rubles. The price (in particular, at which one of the other users other than the exchange initiator evaluates their goods) for a tablet computer (Asus zenpad 10 z300cl) 735 is 15,900 rubles, and the minimum price is 11,130 rubles. The price (in particular, at which one of the other users, different from the initiator of the exchange, evaluates their goods) for the camera (Canon 60D) and lens 745 is 22,500 rubles, and the minimum price is 15,750 rubles. The price (in particular, at which one of the other users, different from the initiator of the exchange, evaluates their goods) for a personal computer and steering wheel 755 is 32,000 rubles, and the minimum price is 22,400 rubles. The price (in particular, at which one of the other users, different from the initiator of the exchange, evaluates their goods) for an ion-block personal computer (iMac 2011) 765 is 45,000 rubles, and the minimum price is 31,500 rubles. The price (in particular, at which one of the other users other than the exchange initiator evaluates their goods) for a tablet computer (iPad Pro 12.9 WiFi + Cellular (LTE)) 775 is 61490 rubles, and the minimum price is 43043 rubles. The price (in particular, at which one of the other users, different from the initiator of the exchange, evaluates their goods) for the 785 projector is 85,000 rubles, and the minimum price is 59500 rubles.

In FIG. Figure 8 shows an example of a general-purpose computer system that includes a multi-purpose computing device in the form of a computer 20 or a server including a processor 21 , a system memory 22, and a system bus 23 that couples various system components, including the system memory to the processor 21 .

Computer 20 may operate in a networked environment through logical connections to one or more remote computers 49 . The remote computer (or computers) 49 may be another computer, server, router, network PC, a peer-to-peer device or other node of a single network, and also usually includes most or all of the elements described above with respect to computer 20 , although only shown information storage device 50 . Logical connections include a local area network (LAN) 51 and a global computer network (GCS) 52 . Such network environments are usually common in institutions, corporate computer networks, and the Internet.

The computer 20 used in the LAN network environment is connected to the local network 51 via a network interface or adapter 53 . Computer 20 used in a GCN network environment typically uses a modem 54 or other means to establish communication with a global computer network 52 , such as the Internet.

The modem 54 , which may be internal or external, is connected to the system bus 23 via the serial port interface 46 . In a networked environment, program modules or parts thereof described with reference to computer 20 may be stored on a remote information storage device. It should be noted that the network connections shown are typical, and other means may be used to establish communication communication between computers.

In conclusion, it should be noted that the information provided in the description are examples that do not limit the scope of this technical solution defined by the formula. The person skilled in the art will understand that there may be other options for implementing this technical solution, consistent with the nature and scope of this technical solution.

Claims (46)

1. A method for automatically forming chains of exchange of goods between users for the subsequent exchange of goods includes the following steps: receive on the server from the user information about the product for exchange, including at least the name of the product, category of the product, subcategory of the product, product tags, cost of the product, “fork” of prices, categories of goods for exchange of interest, geo location of the user; they search on the server for possible goods for exchange taking into account the cost, product category, product subcategory, tags, geo-location to add at least one exchange chain when forming at least one exchange chain as an exchange chain link and sort at least the goods found descending value; in response to the availability of goods that meet these search criteria, at least one goods exchange chain is formed on the server, moreover, when searching for goods for exchange and in the formation of at least one chain of exchange of goods on the server is carried out: - verification of whether at least one product has been found for exchange; - when the fact of the presence of at least one product found is established, the product found is added to the exchange chain; - after adding the found product to the exchange chain, it checks whether the exchange chain length set on the server by the administrator has been reached; - upon reaching the specified length of the exchange chain, the chain is formed and can be presented to the user, otherwise the search for possible goods for exchange continues; - when the fact of the absence of at least one product found is established, the quantity of the length of the exchange chain is checked; - if the length of the exchange chain is greater than one, then the exchange chain is formed and can be presented to the user; - if the length of the exchange chain is less than one, then the exchange chain is not formed and cannot be presented to the user; - present at least one link of the exchange chain of at least one exchange chain received from the server to at least one user on his computing device for subsequent physical exchange of goods between users in the real world within the same exchange chain. 2. The method according to claim 1, wherein when the server searches for possible goods and the server forms the exchange link of the product for exchange, if the type of exchange is Swap to Profit, the goods are searched by the server using the following condition: price Min1 ≤ price Min2 ≤ price Max1 and city = City [ and category1 ∈ desiredCategories2 and Tags1 ∩ DesiredTags2], where - price Min1 - the minimum price of the previous link; - price Max1 - the maximum price of the previous link; - price Min2 - the minimum price of the desired product; - City - the settlement selected on the service; - category1 - category of the previous link; - Desired Categories 2 - (desired) categories of the desired link; - Tags1 - tags of the previous link; - DesiredTags2 - (desired) tags of the desired link; - ∈ is the entry function; - ∩ is the intersection function. 3. The method according to claim 1, in which when the server searches for possible goods for exchange and the server forms the exchange link for the goods, if the type of exchange is Swap to Target, the goods are searched by the server using the following condition: price Min1 ≤ price Min2 ≤ price Max1 and city = City [ and category1 ∈ DesiredCategories2 and category2 ∈ DesiredCategories1 and Tags1 ∩ DesiredTags2 and Tags2 ∩ DesiredTags1], where - price Min1 - the minimum price of the previous link; - price Max1 - the maximum price of the previous link; - price Min2 - the minimum price of the desired product; - City - the settlement selected on the service; - category1 - category of the previous link; - category2 - category of the desired link; - Desired Categories 1 - (desired) categories of the previous link; - Desired Categories 2 - (desired) categories of the desired link; - Tags1 - product tags of the previous link; - Tags2 - product tags of the desired link; - Desired Tags1 - (desired) tags of the previous link; - DesiredTags2 - (desired) tags of the desired link; - ∈ is the entry function; - ∩ is the intersection function. 4. The method according to claim 1, in which the tags are generated automatically by the server using an analysis of the description of the goods and / or analysis of photographs of the goods. 5. The method according to claim 1, in which photos of the goods are added by the server automatically based on the analysis of the description of the goods from the database of photographs and / or the Internet. 6. The method according to claim 1, in which the description and / or tags of the goods are generated by the server based on the analysis of photographs of the goods. 7. The method according to claim 1, in which the user selects at least one product for which he wants to exchange his goods, and / or selects at least one category of goods and optionally at least one subcategory of goods to which the exchanged a product by the user or to which at least one product relates to which the user is ready to exchange his product. 8. The method according to claim 1, in which upon successful formation of the exchange chain, at least one user is sent an alert with an offer about the exchange. 9. The method according to claim 1, in which, when the user refuses to exchange the server, the link associated with the product of the user who refused the exchange is replaced, and the server selects at least one new link in the exchange chain by searching for goods for exchange and adds at least one new link in the exchange chain. 10. The method according to claim 1, in which the user on the server confirms the exchange of goods in the real world, and if the user has more than two goods for exchange, the next such goods for exchange can be added by the user to the server for exchange, and optionally without changing the photos of the goods , product descriptions, tags, categories and subcategories of products.
