ABSTRACT
This paper proposes the formalization and implementation of user model. It is based on an interlocutor's model in natural language dialogue system. Experimental studies on interlocutor's representation and, particularly, on user's familiarization with the system were used for the results analyses. The analysis of the results has shown the more the user is familiarized the more he gives relevant information for research in his first utterances, and with the same number of words. The formalization proposed concerns (1) user's expertise or familiarization level, and (2) the detection of this level. The extended user model allows the system to adapt and thus, to contribute to increase usability and its efficiency in the information research processes.
