Contextual Analysis and Search for Adaptive Information.
The purpose of information retrieval systems (IRS) is to retrieve information that meets the need for information expressed by the user via a request. The research principle is based on the one hand on an upstream process that aims to index the documents via representative terms, on the other hand on the mapping of the representations of the documents thus created and the request being processed in order to to return the documents most likely to meet the needs of the user. Current SRIs and web engines behave in the same way regardless of the search context, the user, the type of need for information and use of information. The CAAS project hypothesis is that taking context into account could improve system performance. The context refers here to implicit or explicit knowledge about the intentions of the user, his environment and the system itself.
