When the information processing server 10 displays only a selection button indicating a community in which a user ID corresponding to the user is registered in response to a login request for a message exchange service from the user, the login process for each community described above. May not be executed. In addition, the information processing server 10 is activated when only a selection button indicating a community in which a user ID corresponding to the user is registered is displayed in response to a login request for a message exchange service from the user. You may comprise so that the login process for every displayed community may not be performed. Further, the information processing server 10 refers to the login necessity setting information in which login necessity is set in advance for each community, and executes the login process only when a login request to a community that requires login is received. You may comprise.

When it is determined that the login request for the message exchange service has not been received (step S10; NO), or after executing the login process for the message exchange service (step S11), the information processing server 10 receives the logout request. It is determined whether or not (step S12). For example, as illustrated in FIG. 10, when logout of the bar area 31 is selected, the terminal device 20 transmits logout request information to the information processing server 10 together with the user ID and the community ID. Note that the information processing server 10 may regard the terminal device 20 that has not received a request or response for a predetermined time or more as being logged out. However, the information processing server 10 performs processing so that the “browsing user” does not log out without making a data transmission / reception request such as a message acquisition request or a message posting request.

In the case of logout, the information processing server 10 performs logout processing (step S13). As shown in FIG. 5, the information processing server 10 records the user ID, the community ID, and the time when the logout request is received (logout time) in the access history DB 12b.

Note that the information processing server 10 uses the message exchange service when the terminal device 20 terminates the application program or web page for the terminal device without logging out the message exchange service provided by the information processing server 10. Information such as the application program to be executed and the time when the web page is terminated may be acquired from the terminal device 20 and recorded in the access history DB 12b.

After the logout process, the information processing server 10 ends the login / logout process subroutine.

(3.3 Example of Posting Message Acceptance Processing)
Next, an operation example of the process for accepting a posted message in the information processing server will be described with reference to FIGS.
FIG. 15 is a flowchart illustrating a subroutine of an operation example of the posted message reception process in the information processing server 10. FIG. 16 is a schematic diagram illustrating a display screen example of the terminal device 20.

As shown in FIG. 15, the information processing server 10 determines whether or not there is a message posting (step S20). Specifically, the system control unit 14 of the information processing server 10 determines whether there is a message transmitted from each terminal device 20. FIG. 17 is a schematic diagram showing an example of a message in the community.

Here, the message input in the terminal device 20 will be described.

For example, when the user taps the message display area 30 of the display unit 20 or a message input button (not shown) on the display unit 23 of the terminal device 20, an input area 34 and a software keyboard appear as shown in FIG.

When the user of the terminal device 20 inputs a message in the input area 34 and selects an input completion button or a posting button (not shown), the terminal device 20 processes the user ID and community ID together with the input message. Send to server 10.

If the information processing server 10 determines that a new message has not been posted (step S20; NO), the information processing server 10 ends the subroutine of the posted message reception process.

If the information processing server 10 determines that a new message has been posted (step S20; YES), the information processing server 10 stores the posted message (step S21). Specifically, the system control unit 14 receives the message (post information) transmitted from the terminal device 20 together with the received user ID and community ID and the post time when the message was received, as shown in FIG. Record in order. As illustrated in FIG. 14, for each community, the posting time, the message, and the like are recorded in the posting history DB 12 c in the order of the posting time when the message is posted.

(3.4 Example of operation for generating message browsing auxiliary information)
Next, an operation example of message browsing auxiliary information generation processing in the information processing server will be described with reference to FIGS. 18 and 19.

FIG. 18 is a flowchart showing a subroutine of an operation example of the process for generating the message browsing auxiliary information in the information processing server 10. FIG. 19 is a schematic diagram illustrating a display screen example of the terminal device 20.

As shown in FIG. 18, the information processing server 10 determines whether or not the posted value in the unviewed period is greater than or equal to a threshold value (step S30). Specifically, the system control unit 14 of the information processing server 10 refers to the access DBb, and compares the login time when logging in to the community and the time when the previous access was completed (logout time or time when access was terminated). It is determined whether or not the posting value of a message posted to the community whose posting time is included in the interval (unviewed period) is greater than or equal to a threshold value.

As described above, when the user accesses the community, the information processing server 10 has a posting value of a message posted to the community between the access time of the access and the time when the previous access ends, which is equal to or greater than a threshold value. In this case, it functions as an example of message browsing auxiliary information providing means for providing the generated message browsing auxiliary information.

When it is determined that the posting value in the unviewed period is not equal to or greater than the threshold (step S30; NO), the information processing server 10 determines whether the posting state satisfies a predetermined condition (step S31). Specifically, the system control unit 14 refers to the access DBb and calculates a posting state in the community when the user logs in to the community page. For example, the system control unit 14 calculates the latest posting value (the number of postings and the posting amount) per unit time. The most recent time is a predetermined time (5 minutes, 10 minutes, 15 minutes, 30 minutes, etc.) before the login time. Further, the system control unit 14 may calculate the amount of change in the posted value per unit time, and calculate whether the posting is growing as the posting state.

Then, the system control unit 14 determines whether the calculated posting value per unit time is equal to or greater than a threshold as a predetermined condition.

Thus, the information processing server 10 functions as an example of a message browsing auxiliary information providing unit that provides the generated message browsing auxiliary information according to the posting state in the community when the user accesses the community. To do.

When it is determined that the posting state does not satisfy the predetermined condition (step S31; NO), the information processing server 10 determines whether a user operation has been detected. (Step S32). Here, as an example of the user operation, as illustrated in FIG. 13, an operation in which the user tries to create a new message, an operation in which the user tries to view the message, and the like can be given.

Specifically, the system control unit 14 determines whether or not a user operation is detected based on a request or signal from the terminal device 20.

For example, when the user intends to create a new message, the terminal device 20 requests the information processing server 10 for a screen as shown in FIG. 13, or the user taps the display unit 23 and the input area 34 is displayed. When it appears, the terminal device 20 transmits a signal to the information processing server 10. When the user wants to view the message, the user performs a scroll operation on the display unit 23 screen, and further data is required, and the terminal device 20 requests the information processing server 10 for the data, or there is a scroll operation. The terminal device 20 transmits a signal to that effect to the information processing server 10.

As described above, the information processing server 10 functions as an example of a message browsing auxiliary information providing unit that provides the generated message browsing auxiliary information when a predetermined operation is detected from a user who has accessed the community.

If it is determined that no user operation is detected (step S32; NO), the information processing server 10 ends the message browsing assistance generation processing subroutine. That is, if all of the processing from step S30 to step S32 is “NO”, the information processing server 10 ends the message browsing assistance generation processing subroutine.

In addition, you may change the order of step S30 which is the said determination process from step S30. Moreover, you may perform only one part process among the processes of step S30 to step S32 which are the said determination processes.

When it is determined that the posting value in the unviewed period is equal to or greater than the threshold (step S30; YES), or when it is determined that the posting state satisfies a predetermined condition (step S31; YES), or the user When it is determined that the operation is detected (step S32; YES), the information processing server 10 generates a message group (step S33).

As illustrated in FIG. 14, the system control unit 14 refers to the posting history DB 12c and sets a message group MG1, MG2,... MGn including at least one message based on the posting time. At least one is generated.

In the separation of these message groups MG1, MG2,... MGn, messages are separated so that the posting information is gathered based on the posting time and the posting value between the posting information. Separating messages so that post information is collected based on post time and post value between post information is, for example, post information posted within a first predetermined time from the post time when the first post information was posted In addition, the posting information with the largest posting time interval of continuous posting information among multiple posting information, or the posting information with the posting time interval of continuous posting information being greater than or equal to a predetermined value, is divided between For example, the posting times are relatively dense among the plurality of posting informations, and the posting information groups are relatively dense. A message group including at least one message is generated based on the posting time when the message was posted.

The system control unit 14 may group only unread messages that have not been logged in immediately before with reference to the access history DB 12b. Further, the message may be divided starting from a message in which a specific word (such as “By the way”) whose topic is likely to change appears.

Here, as an example where the posted value is relatively high, the posted value (the number of posted posts, the number of characters included in the posted message) in the second predetermined time frame (for example, 5 minutes or 10 minutes) is equal to or greater than the predetermined value. In this case, the posted value is set in advance in association with the time period including the second predetermined time frame, or when the posted value is higher than other predetermined time frames close in the second predetermined time frame. The case where it is high compared with the assumed contribution value which exists, the case where it is high compared with the contribution value of the other community in the said 2nd predetermined time frame, etc. are mentioned. Note that not all messages need to belong to a message group, and in that case, there may be messages that do not belong to any message group.

Note that the system control unit 14 may extract a keyword from a posted message and generate a message group including at least one message based on the extracted keyword. For example, the system control unit 14 groups only messages having a common keyword or a similar keyword. Further, the system control unit 14 may group only messages having related keyword keywords. For example, the system control unit 14 refers to the dictionary DB 12e to make messages including soccer-related words (soccer and lower concept words) into message groups. Further, the system control unit 14 may make a message group a message including a common keyword, a similar keyword, or a related keyword and within a predetermined time.

Further, the system control unit 14 displays a posted message sandwiched between a message including a common keyword, a similar keyword, or a related keyword and a message including the common keyword, a similar keyword, or a related keyword. It may be.

In addition, messages in the message group do not have to be messages in which the posting order is continuous. For example, the extracted keyword may be similar (including a relation), and the posting time may be a message within a predetermined range.

As described above, the information processing server 10 functions as an example of a message group generation unit that generates at least one message group from the messages stored in the storage unit in order of the posting time when the messages are posted. The information processing server 10 functions as an example of a keyword extracting unit that extracts a keyword from the posted message. Further, the information processing server 10 functions as an example of a message group generation unit that generates a message group including at least one message based on the extracted keyword. In addition, the information processing server 10 determines, based on the interval of the posting time between the posting time of the message and the posting time of the message different from the message, from the messages stored in the storage unit in the order of the posting time. It functions as an example of a message group generation unit that generates a message group including at least one message. Further, the information processing server 10 acquires a feature keyword from the message corresponding to the user for each user corresponding to the message included in the specified message group as message group information, and based on the acquired feature keyword It functions as an example of message group generation means for generating message browsing auxiliary information.

Next, the information processing server 10 specifies a message group (step S34). Specifically, the system control unit 14 refers to the access history DB 12b and identifies a message group including unread messages that the user has not browsed for the message groups MG1, MG2,. For example, the system control unit 14 refers to the access history DB 12b and is posted to the accessed community that includes the posting time between the access time of the access and the time when the previous access ended (unviewed period). Identify unread messages. The system control unit 14 specifies a message group including an unviewed message.

Note that the information processing server 10 may determine the login duration from the login time, estimate the estimated browsing amount at the time of login, and specify the message group.

For example, when message browsing information is generated and displayed when a user tries to input a message, the system control unit 14 obtains a login duration from the login time to the input time. And the system control part 14 estimates the browsing estimated amount according to login continuation time. At this time, based on the average browsing amount per unit time, the average browsing amount for each community, the average browsing amount for each user, etc., the system control unit 14 browses according to the login duration time. Estimate the estimator. When the estimated browsing amount is large, for example, the system control unit 14 removes a message with an old time from an unviewed message or removes a message with a new time to reduce an unviewed message. Thus, the system control unit 14 updates the unviewed message based on the estimated browsing amount. And the system control part 14 produces | generates a message group from the updated unread message, and specifies a message group.

In this way, the information processing server 10 identifies an unread message posted to the accessed community during a period between the access time when the community is accessed and the access end time when the previous access is completed. It functions as an example of browsing message specifying means. In addition, the information processing server 10 functions as an example of a browsing amount estimation unit that estimates a browsing amount in the access based on an access continuation time from an access time when the community is accessed. Moreover, the information processing server 10 functions as an example of an unviewed message update unit that updates the unviewed message based on the estimated browsing amount. The information processing server 10 functions as an example of a message group specifying unit that specifies a message group including the updated unviewed message.

When the system control unit 14 estimates the estimated browsing amount and the estimated browsing amount is large, the number of message groups is determined so as not to identify a message group with an old time or a message group with a new time. May be reduced.

Note that the information processing server 10 may specify a message group with more concentrated posting times. For example, a message group having a higher posting value such as the number of posts per unit time, a posting amount, and a posting density is specified. The system control unit 14 may specify all the message groups MG1, MG2,. Moreover, the message interval may be shorter as a message with more concentrated posting times.

Specifically, the system control unit 14 specifies a message group in which the posting times are more concentrated with respect to the message groups MG1, MG2,. For example, a message group having a higher posting value such as the number of posts per unit time, a posting amount, and a posting density is specified. Examples include a case where a posting value such as the number of posts per unit time is higher, or a case where a message interval is shorter. The number of posts per unit time obtained by dividing the number of posts of the message group (for example, MG1) by the time of posting of the last message (for example, MG1) from the posting time of the first message of the message group (for example, MG1) Find and compare with the number of posts per unit time for other messages. In the same message group, a message group having a high contribution density in the partial period may be specified by obtaining the contribution density in the partial period from the posting time of the first message to the ending time of the message in the message group. .

In this way, when the user accesses the community page, the information processing server 10 is based on the participation history information of the accessed user with respect to the community, and the accessed user among the generated message groups. Functions as an example of a message group specifying means for specifying the message group including a message that is not viewed.

Next, the information processing server 10 generates message browsing auxiliary information (step S35). Specifically, as the message group information that is information about the message group, the system control unit 14 obtains keywords such as nouns and verbs from the messages of the specified message groups, and then extracts and acquires characteristic keywords. To do. For example, examples of the characteristic keyword include a keyword having a large number of postings or appearances and a keyword calculated by idf (Inverse Document Frequency).

Note that the feature keyword may be obtained after deleting a predetermined word, word, symbol, or the like. The system control unit 14 may weight each keyword according to the elapsed time from the posting time. For example, the new message keyword may be more influential, and the weight may be increased for the new message keyword. Here, all the acquired message group information may be used as message browsing auxiliary information, or a part of the acquired message group information may be used as message browsing auxiliary information.

Furthermore, the system control unit 14 may count the number of postings or the number of appearances of the keyword in units of categories with reference to the dictionary DB 12e. For example, the keywords “World Cup” and “Soccer” may be assigned to the keywords “Japan National Team” and “Brazil National Team”. The keyword “world cup” may be assigned to the keyword “soccer”. Further, the keyword “ΔΔ player” at the same level may be assigned to the keyword “◯ ● player”.

Then, as shown in FIG. 11, the information processing server 10 acquires characteristic keywords of the specified message groups MG1, MG2,... MGn, and generates message browsing auxiliary information. For example, as shown in FIG. 11, the characteristic keyword “soccer” of the message group MG1, the characteristic keyword “world cup” of the message group MG2,... Browsing auxiliary information 40a is generated.

In addition, the information processing server 10 may generate the message browsing auxiliary information by acquiring the characteristic keyword from the message corresponding to the user for each user corresponding to the message included in the message group specified as the message group information. Good. For example, as shown in FIG. 19, in the specified message group MGn, a feature keyword (message browsing auxiliary information 41a) may be displayed for each participating user. Thus, the information processing server 10 may process the acquired message group information to generate message browsing auxiliary information.

Further, the information processing server 10 acquires feature keywords from the message corresponding to the user specified according to the number of messages included in the message group specified as the message group information, and generates message browsing auxiliary information. Also good. Characteristic keywords for users who are sending many messages among users participating in the community are acquired. For example, as shown in FIG. 19, the display of a specific user (Ms.sC) may be emphasized. Thus, the information processing server 10 may process the acquired message group information to generate message browsing auxiliary information.

Further, the information processing server 10 may display a message (for example, a message including a characteristic keyword) as message browsing auxiliary information. The information processing server 10 may acquire messages of users who are sending many messages among users participating in the community as message group information, and generate and display message browsing auxiliary information. Further, the information processing server 10 may acquire all unread messages as message group information, and generate and display message browsing auxiliary information.

Further, the information processing server 10 may extract feature keywords from all unread messages and provide them as topics in unread messages. Further, the information processing server 10 may extract feature keywords from all messages of users who are currently logged in to the community among unviewed messages.

In this way, the information processing server 10 functions as an example of a message browsing auxiliary information generation unit that acquires information about the identified message group and generates message browsing auxiliary information based on the acquired information about the message group. . In addition, the information processing server 10 determines, based on the interval of the posting time between the posting time of the message and the posting time of the message different from the message, from the messages stored in the storage unit in the order of the posting time. It functions as an example of message browsing auxiliary information generating means for generating a message group including at least one message. In addition, the information processing server 10 uses the message corresponding to the user specified according to the number of posted messages included in the message group for each user corresponding to the message included in the specified message group as message group information. It functions as an example of message browsing auxiliary information generation that acquires a characteristic keyword and generates message browsing auxiliary information based on the acquired characteristic keyword.

Next, the information processing server 10 performs a display control process for the generated message group browsing auxiliary information (step S36). Specifically, in order to provide the acquired message group information to the terminal device 20, the system control unit 14 displays a message on the display unit 23 of each terminal user 20 of the community as shown in FIG. The message display control process is performed so that the message browsing auxiliary information 40a is displayed in the browsing auxiliary information display area 40. That is, the information processing server 10 transmits the generated message group browsing auxiliary information to the terminal device 20 and provides it.

For example, in the case of an application program for a terminal device, the information processing server 10 transmits data in the message browsing auxiliary information display area 40 to the terminal device 20. In the case of a web page, the information processing server 10 generates web pages for the message browsing auxiliary information display area 40, the message display area 30, and the bar area 31, and transmits them to the terminal device 20.

Next, the information processing server 10 ends the subroutine for generating message browsing auxiliary information.

Thus, the information processing server 10 functions as an example of a message browsing auxiliary information providing unit that provides the generated message browsing auxiliary information.

As described above, according to the present embodiment, the flow of conversation in the community from the message browsing auxiliary information 40a generated based on the message group information of the message group including the message that has not been browsed by the user who has accessed and joined the community. Can be easily grasped, messages can be easily posted to the community, participation of a service for exchanging messages with other users is encouraged, and network resources can be used effectively.

In addition, when a keyword is extracted from a posted message and a message group including at least one message is generated based on the extracted keyword (for example, a word related to soccer), regarding a certain theme (for example, soccer), Since there is a high possibility that a predetermined keyword will appear, a message group in which messages according to the theme are collected can be generated.

In addition, when groups grouped in order at the posting time are separated according to the posting time interval to generate message groups MG1, MG2,..., MGn, messages are exchanged with a predetermined theme for a certain period of time. Since there is a high possibility that messages are exchanged with other themes in time, grouping according to the theme for each hour can be performed.

Further, when acquiring a characteristic keyword from a message corresponding to a user specified according to the number of messages included in the message group specified as message group information, the information is specified according to the number of messages included in the message group. It is possible to grasp the characteristics of a message of a user, for example, a user who has posted many messages. Conversely, it is possible to capture the characteristics of a user's message that has a small number of postings but may have a weight in a statement.

In addition, for each user corresponding to the message included in the message group specified as the message group information, when the characteristic keyword is acquired from the message corresponding to the user, the content of each person's utterance can be grasped.

In addition, an unread message posted to the logged-in community is identified between the login time and the last access time, and the amount of browsing at the time of the login based on the access duration from the login time When the unviewed message is updated based on the estimated estimated browsing amount and the message group including the updated unviewed message is specified, the estimated browsing amount estimated according to the user's access duration is calculated. It is possible to flexibly specify a message that the user is not browsing.

Further, when providing the message browsing auxiliary information 40a generated based on the specified message group information according to the posting state in the community when the user logs in to the community, for example, posting is frequently performed. Since the message browsing auxiliary information 40a is generated based on the information about the message group specified according to the situation such as when there is no room to check the unread message, such as when it is in the state of It can be grasped flexibly according to the posting state in the community.

In addition, when the posting value of a message posted to the community between the login time and the last access time when the user logs in to the community is equal to or greater than a threshold, the generated message browsing auxiliary information is displayed. When providing, for example, when there are a large number of posts, such as when postings are frequently made, and it is difficult to check messages, past posting contents can be flexibly changed according to the posting status in the community I can grasp it.

In addition, when a predetermined operation is detected from a user logged in to the community, when providing the generated message browsing auxiliary information, when browsing, when a user operation such as inputting a message, Without reading all the messages, it is possible to assist so that the content of the conversation in the community can be grasped flexibly according to the operation of the user.
