Abstract

L'invention concerne un dispositif (100) de traitement d'une requête de recherche (112, 112') comportant un récepteur de requête (110) destiné à recevoir une requête de recherche d'un premier utilisateur (USER1) et un catégorisateur (120) destiné à affecter la requête de recherche à une catégorie à partir d'une pluralité de catégories différentes. Le dispositif comporte également un déterminateur de partenaire de communication (130) destiné à déterminer un deuxième utilisateur (USER2) ayant formulé une requête de recherche affectée à la même catégorie, et un fournisseur d'informations (150) destiné à fournir une information (152) au premier utilisateur, ladite information indiquant que le deuxième utilisateur ayant formulé une requête de recherche de la même catégorie existe, et à fournir une information (154) au deuxième utilisateur, ladite information indiquant que le premier utilisateur ayant formulé une requête de recherche de la même catégorie existe. Ledit concept peut également être implémenté en tant que procédé et programme informatique. Ledit concept permet aux utilisateurs formulant des requêtes de recherche de la même catégorie d'entrer dans une communication électronique directe. Un échange de connaissances très efficace est ainsi garantit entre différents utilisateurs dudit dispositif.
