Pour une sémiotique des traces

Pour une ergonomie cognitive des dictionnaires électroniques

We compare a linguistic/psycholinguistic approach of the organisation of the mental lexicon with a computational approach of the implicit lexical organisation in dictionaries taken as graphs and whose structure is a “small world”. This double approach aims at showing that if the implicit structure of dictionaries, mathematically identified, is adequate with the way young children categorise, th...

Une approche qualitative spatiale pour une description sémantique des reliefs

Modélisation des métadonnées pour une recomposition dynamique des documents

This paper presents a solution to cope with document management problems. This solution is based on a document warehouse enriched by metadata (for each media type) elicited, modeled and structured in meta-documents. To homogenize these meta-document representation, we use a document indexing and segmentation process. The warehouse thus created is seen as the hyperbase to which the user will app...

Méthodologie pour une représentation multi-dimensionnelle des documents

The representation of documents and queries in Information Retrieval (IR) is mostly a one-dimensional (vector) representation. This representation has limitations: For example, how to represent a multi-topical document or an ambiguous query? These issues are crucial for the development of interactive systems or for diversification. Beside heuristics models that cannot be generalized, most repre...
