Abstract

This paper deals with the modeling of time, aspect and verbal meanings in natural language processing within Simple Conceptual Graphs (SCG) by way of Semantico-Cognitive Schemes (SCS) and the aspecto-temporal theory. The expression of a semantico-cognitive representation within SCGs is automatically tractable. The SCS allows us to build a representation of a text taking into account the information about time and aspect. It allows us to represent fine subtleties of natural language. On the other hand, the Conceptual Graphs formalism provides a powerful inferential mechanism which makes it possible to reason from texts. Our work bears on French texts. A text is represented by two different structures both represented within the SCG model. The first structure models the semantico-cognitive representation while the second one is the temporal diagram representing the temporal constraints between the situations described in the text. Linking these structures leads us to slightly extend the original SCG model.
