BBN Science Development Program AI Seminar Series Lecture COMPLEXITY AND DECIDABILITY OF TERMINOLOGICAL LOGICS Peter F. Patel-Schneider AI Principles Research Department AT&T Bell Laboratories (pfps@allegra.att.com) BBN Labs 10 Moulton Street 2nd floor large conference room 10:30 am, Tuesday November 29 Terminological Logics are important formalisms for representing knowledge about concepts and objects, and are attractive for use in Knowledge Representation systems. However, Terminological Logics with reasonable expressive power have poor computational properties, a fact which has restricted their use and utility in Knowledge Representation systems. This talk gives a brief description of Terminological Logics, presents some results concerning their tractability and decidability, and discusses the role of Terminological Logics in Knowledge Representation systems. -------
