This paper describes a natural language processing system implemented at Hewlett-Packard's Computer Research Center. The system's main components are: a Generalized Phrase Structure Grammar (GPSG); a top-down parser; a logic transducer that outputs a first-order logical representation; and a "disambiguator" that uses sortal information to convert "normal-form" f i r s t - o r d e r logical expressions into the q u e r y language for HIRE, a relational database hosted in the SPHERE system. We argue that theoretical developments in GPSG syntax and in Montague semantics have specific advantages to bring to this domain. | PROCESSING ENGLISH WITH A GENERALIZED PHRASE STRUCTURE GRAMMAR Jean Mark Gawron Jonathan King John Lamping Egon Loebner E.

The system s main components are a Generalized Phrase structure Grammar GPSG a top-down parser a logic transducer that outputs a first-order logical representation and a disambiguator that uses sortal information to convert normal-form first-order logical expressions into the query language for HIRE a relational database hosted in the SPHERE system. We argue that theoretical developments in GPSG syntax and in Montague semantics have specific advantages to bring to this domain of computational linguistics. The syntax and semantics of the system are totally domain-independent and thus in principle highly portable. We discuss the prospects for extending domain-independence to the lexical semantics as well and thus to the logical semantic representations. 1. INTRODUCTION This paper is an interim progress report on linguistic research carried out at Hewlett-Packard Laboratories since the summer of 1981. The research had three goals 1 demonstrating the computational tractability of Generalized Phrase Structure Grammar GPSG 2 implementing a GPSG system covering a large fragment of English and 3 establishing the feasibility of using GPSG for interactions with an inferencing knowledge base. Section 2 describes the general architecture of the system. Section 3 discusses the grammar and the lexicon. A brief dicussion of the parsing technique used in found in Section 4. Section 5 discusses the semantics of the system and Section 6 presents -a detailed example of a parse-tree complete with semantics. Some typical examples that the system can handle are given in the Appendix. The system .
