L'aide à l'accès à l'information géographique: un environnement de conception coopérative d'utilisations de données géographiques

Abstract : Geographical data are rich information resources. Users' access to these resources is difficult, especially because users do not know how to interpret and manipulate representations of geographic space in these data. In this work, we first propose a formalisation of the general issue of users' access to information resources. We then analyse techniques to enhance this access, in whichever field of information they take place. The most promising is to describe resources and apply the following principle : to distinguish and integrate knowledge describing a domain of interest, the WHAT, and knowledge about the manipulation of objects of this domain, the HOW. We evaluate the application of this principle in the field of geographic information. We then propose a contribution that focuses on the lack of representation of HOW knowledge about geographic information resources. This contribution is concretised by a specific model, integrating the notions of tasks and roles. This model is formalised by a Backus Naur Form grammar. It is associated to a co-operative problem-solving environment that assists users in adapting template of data manipulation to their own need for geographic knowledge. A prototype of this system is proposed.
