In the case of ontologies, this can be expressed through a set of rules.

Specifically, in the example, if the match function indicates a match between the target user profile and the local user profile a positive response message is transmitted. This message does not answer the query but just whether the second user is willing to discuss it with first user and has a suitable profile match. If the decision is to ask the second user, the second communication unit 103 will display the request for the second user to make the decision to reply or to refuse.

  • the propagation criterion can simply be a limit on the number of times the request message can be forwarded.

If this value exceeds the threshold, the request can be propagated, and then the second communication unit 103 becomes a sub-initiator of the original request. In this example, the second communication unit 103 decides to propagate the target user profile.

  • the propensity to propagate the request to a particular node is also linked to the matching result between the requested profile and the perceived profile relating to this node. Based on these assumptions, it is possible to define the decision to propagate the query at node i as a function of these parameters:
  • path_length(7-,z) represents the social distance from the initiator r of the query
  • matching(g, ⁇ ) represents the output of the matching algorithm between the requested profile q and the perceived profile of n, which i may propagate the query to; • a and ⁇ are constants whose value is established thanks to a simulated environment.
  • a reliability (or trust) value can be assigned to different users.

Abstract

La présente invention a trait à une première unité de communication (101) comportant une unité de stockage de profils (207) pour le stockage d'un ensemble de profils d'utilisateurs pour un groupe d'utilisateurs d'autres unités de communication (103-109). En réponse à une interrogation, un processeur de profils (203) détermine un profil d'utilisateur cible. Un processeur de sélection (205) sélectionne un/des profil(s) d'utilisateur correspondant(s) à partir de l'ensemble de profils d'utilisateurs, et un contrôleur de transmission (211) transmet un message de demande à/aux l'unité/unités de communication (103-109) de/des l'utilisateur/utilisateurs identifié(s). L'unité/les unités de communication de réception compare(nt) le profil d'utilisateur cible reçu à un profil d'utilisateur stocké localement pour l'utilisateur identifié et transmet un message de réponse positive s'il y a correspondance et selon la politique de réponse définie par un utilisateur local. En réponse au message de réponse positive, la première unité de communication (101) présente une information d'identité pour l'utilisateur identifié permettant l'entrée en contact de l'utilisateur appelant avec l'utilisateur identifié.
