"text": "The KAI,II'SOS prototype we have developed at the IBM Paris Scientific Center is able to analyze texts written in l;reneh and to produce a semantic representalion of these texts expressed as a set of inter-related Conceptual Graphs [6, 1] . It uses a semantic lexicon which contains, for each word to be defined, one or more Conceptual Graphs corresponding to one or more meanings of the word. The KAI,IPSOS questkm/answefing system analyzes a Natural l.anguage query, translates it into Conceptual Graphs, performs pattern matching and deduction on these text graphs to select the answer, and finally generates a Natural Iangmage answer fiom the selected answer graphs.",

"text": "First, we must remind you how the concept type hierarchy is the necessary basis for any use of the Conceptual Graph model. The reader may of course refer to [6]. In the Conceptual Graph model, the concept types are not supposed to be words but abstract symbols (atoms) used to denote a concept. Ia'or example, we could have COMMU-NICATION-I~I1OCESS as the concept type that occurs in the definition of the verbs \"to say\", \"to communicate\", \"to discuss\", etc. In the same way, a polysemic word like %at\" should point on distinct graphs containing STICK and ANIMAl, as primitive concept types. It appears that the concept type hierarchy must also contain chains like:",
