Towards an architecture for personalized information retrieval implying the user's profile and votes

International audienceInformation Retrieval is a process made by a user to obtain relevant information which meets his needs using an Information Retrieval System (IRS). However the IRS shows some differences between user relevance and system relevance. These variations are primarily related to the imperfection of the indexing process (approach directly related to the IR) and specially the non consideration of the user profile. This paper presents a study about formalisms proposed in the literature and addresses some reflections to deal with problems arising from this survey, in order to satisfy the final user in Information Retrieval process
