Section: Scientific Foundations

Introduction

This section details several research 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 techniques on usage data (cf. section  3.3.1 ) ?

• How to synthesize and exhibit information by applying KDD techniques 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 ) ?
