Une exploration de la structure sémantique du lexique adjectival français

This paper presents an exploration of a lexical graph, within the framework of lexical semantics. The aim of the exploration is reveal the structure of the lexicon modelled by the graph so an automatic system can reach the information it contains. We developed geometric tools to build a semantic space associated with the graph. The topology of this space can account for the topology of the graph. These tools were developed using a graph of adjectival synonymy and its scale-free small-world structure. We now want now to use them to explore any lexical graph, and more generally any graph related to human activities.
