ARTIFICIAL INTELLIGENCE SEMINAR, Tuesday, August 6, 3 pm., SF1105 (SF = Sandford Fleming Building, 10 King's College Road) "Interpreting Descriptions in a Prolog-based Knowledge Representation System" Randy Goebel University of Waterloo Abstract: Descriptions provide a syntactic device for abbreviating expressions of a formal language. We discuss the motivation for descrip- tions in a system called DLOG. We describe two approaches to specifying their semantics, and a method for implementing their use. We explain why some descriptions should be given a higher order interpretation, and explain how such descriptions can be interpreted in the simpler logic of Prolog. The essential idea is to constrain the domain of descriptions so that an extended unification procedure can determine description equivalence within the Prolog framework. -- Jim Clarke -- Dept. of Computer Science, Univ. of Toronto, Canada M5S 1A4 (416) 978-4058 {allegra,cornell,decvax,ihnp4,linus,utzoo}!utcsri!clarke
