TAILIEUCHUNG - Báo cáo khoa học: "SITUATION SEMANTICS AND MACHINE TRANSLATION."

Situation Semantics is one of the most recent and controversial theories in formal semantics. Machine Translation (MT) is a highly complex application domain, in which research is expensive of both time and resources. On the surface, the space for interaction between these two fields would seem fairly limited, and in practice the the application of formal semantics in MT has been very limited, a notable exception being the Rosetta project (Landsbergen 1982, 1987). | SITUATION SEMANTICS AND MACHINE TRANSLATION. c J. Rupp CCL UMIST . Box 88 Manchester M60 1QD Introduction Situation Semantics is one of the most recent and controversial theories in formal semantics. Machine Translation MT is a highly complex application domain in which research is expensive of both time and resources. On the surface the space for interaction between these two fields would seem fairly limited and in practice the the application of formal semantics in MT has been very limited a notable exception being the Rosetta project Landsbergen 1982 1987 . The abstract translation problem however remains and any application must be based on some formalisation of the problem. The purpose of this paper is demonstrate that the enriched theoretical vocabulary of Situation Semantics offers a more intuitive characterisation of the translation process than was possible using more traditional semantic theories. This demonstration will take the form of a formalisation of the most commonly used method for MT in terms of Situation Semantic constructs. In this respect this paper follows on from a previous paper Johnson Rosner Rupp 1988 in which MT was presented as a testing ground for semantic representation languages. This paper will turn the issue around and consider what the theory of Situation Semantics has to offer to an MT application. The abstract description of the MT system to be considered will therefore remain the same. The paper consists of a basic introduction to the machinery of Situation Semantics an examination of the problem of translation a formal description of a transfer-based MT system and some examples of the kind of lexical transfer one would expect to define in such a system. Situation Semantics The Basics. Situation Semantics is an informational approach to formal semantics. The philosophical basis of this theory is laid out in Barwise and Perry s Situations and Attitudes 1983 henceforth B P . Most of the structure of the theory can be seen as .
