User Modeling and Instance Reuse for Information Retrieval Study Case: Visually Disabled Users Access to Scientific Documents

Lobna Jeribi, Beatrice Rumpler, and Jean Marie Pinon

In this paper we present an Information Retrieval System (COSYDOR) designed for sightless students or researchers, to improve their access to scientific information. Our approach consists in reusing search instances in order to help these users when querying COSYDOR. Thus, In the first part we define a search instance model, including our proposed user model. Then we present our approach of Case Based Reasoning applied on this model and we describe the instances reuse process. In the last part we briefly describe our prototype and show the experimental evaluations results.
