Résumé :
As both the volume of data and the diversity of users accessing them increase, user preferences offer a useful means towards improving the relevance of the query results to the information needs of the specific user posing the query. In this talk, we will focus on enhancing preferences with context. Context may express conditions on situations external to the database or related to the data stored in the database. We will outline models for expressing both types of preferences. Then, given a user query and its surrounding context, we will consider the problem of selecting related preferences to personalize the query.
