Abstract : This paper proposes some formal tools for representing the semantic content of French expressions referring to space. These tools consist of first, a relational –or qualitative– geometry encompassing topology, distance notions and projective geometry, as well as temporal notions, thus constituting a rather complete theory of naive space-time; and second, several formalisms to deal with functional aspects of entities such as intrinsic orientation, internal structure and categorizing; more generally, it is claimed that a representation in three levels geometric, functional and pragmatic is required to account for spatial expressions- semantics. To analyze the semantics of some of these expressions, this work systematically looks for valid reasoning schemata involving them; this approach also enables the testing of the proposed formal system as well as the evaluation of the definitions obtained for the studied lexemes.
