Section: Scientific Foundations

Introduction

This section details the questions that we want to answer to:

• 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 ``informatio systems data mining''.
