@TECHREPORT{AICPub545:1987, AUTHOR={Pereira, Fernando C. N.}, TITLE={Grammars and Logics Of Partial Information}, ADDRESS={333 Ravenswood Ave., Menlo Park, CA 94025}, INSTITUTION={AI Center, SRI International}, MONTH={Apr}, NUMBER={420}, YEAR={1987}, KEYWORDS={Natural Language!Unification grammar, Logic Programming}, ABSTRACT={This paper is an informal survey of models of grammatical categories in unification-based formalisms from computational linguistics and their relationship to current logic programming concepts. The basic notion of partiality in the informational content of grammatical categories is introduced, and specific automata-theoretic, denotational and logical models of partial information are outlined. The expression of disjunction, negation, inheritance and indeterminate constraints in categories is also discussed.} }
