TAILIEUCHUNG - Báo cáo khoa học: "The key role of semantics in the development of large-scale grammars of natural language"

The aim of this paper is to show how large-scale (computational) grammars of natural language benefit from an organization of semantics which is based on Minimal Recursion Semantics (MRS; Copestake et al. (1999)). This we are doing by providing an account of valence alternations in German based on MRS, showing how such an account makes a computational grammar more efficient and less complicated for the grammar writer. | The key role of semantics in the development of large-scale grammars of natural language Valia Kordoni Department of Computational Linguistics University of Saarland PO Box 15 11 50 D-66041 Saarbriicken Germany kordoni@ Abstract The aim of this paper is to show how large-scale computational grammars of natural language benefit from an organization of semantics which is based on Minimal Recursion Semantics MRS Copestake et al. 1999 . This we are doing by providing an account of valence alternations in German based on MRS showing how such an account makes a computational grammar more efficient and less complicated for the grammar writer. 1 Introduction The valence alternations in German that we focus on in this paper are the ones involving direct internal arguments . objects and indirect prepositional complements NP . V NPj P NP NP . V NPj P NPj where the indices denote referential identity. Such alternation patterns in German characterize among others the behaviour of verbal predicates which participate in the so-called Locative Alternation phenomena. 2 Locative Alternation in German Overview The verbs giefien anA fallen Consider the following sentences in German 1 Peter goB die Blumen mit Wasser. Peter poured the with water Peter watered the flowers . 2 Peter goB Wasser auf die Blumen. 3 Peter finite den Tank mit Wasser . filled the with water Peter filled the tank with water . 4 Peter fiillte Wasser in den Tank. l - 4 are examples of German predicates which participate in the so-called Locative alternation phenomena see among others Dowty 1991 Rappaport and Levin 1988 Levin and Rapapport Hovav 1991 . Alternations in German with the locative verbs fallen fill and giefien pour are of the general form presented in Section 1 . The main features of these verbs in German English Modem Greek and some other languages is that they are morphologically identical and that they involve two arguments one denoting a location and one
