National audienceThis paper presents a work on a comparison between a user model and user's behavior based on three premises. First, any system includes a representation of its users. Second, the external representation of users in a system is related to how the system is used by users. Third, knowing how to use the system depends on the task context. For making context explicit in order to use it, we use contextual graphs to capture the effective behaviors of users in an activity of information retrieval on a scientific website. We show how such a context-based representation may help to predict the search behavior of visitors to the website pages. We extend the capability of the system by a preliminary study based on a technique of eye tr...
