Intelligent problem solving systems must be able to ex- press their results in a coherent and flexible manner. One way this can be done is by eztemporaneous elaboration, the method of language production that underlies more skilled tasks such as explanation. This paper outlines a computa- tional model for extemporaneous elaboration that is imple- mented in a computer model called Extemper, shows ex- amples of its operation, and compares it with other models of language production. Extemper contains the four com- ponents minimally required for elaboration: 1) an efficient method for linearizing a knowledge structure, 2) a translation/selection mechanism for producing a conceptual textbase from the knowledge structure, 3) local coherence operators which provide local connections between text...
