Section: Scientific Foundations
This section details several questions we want to address:
How to support the semantics specification and the design of hypertext information systems (cf. section 3.2 ) ?
How to evaluate information systems by applying KDD technics on usage data (cf. section 3.3.1 ) ?
How to synthesize and exhibit information by applying KDD technics on documents (cf. section 3.3.2 ) ?
How to support users in their information retrieval task and how to design information systems supporting the evolution of user practices (cf. section 3.4 ) ?
The second and third questions concern ``information systems data mining''.
