Báo cáo khoa học: "The Computational Lexical Semantics of Syntagmatic Relations"

In this paper, we address the issue of syntagmatic expressions from a computational lexical semantic perspective. From a representational viewpoint, we argue for a hybrid approach combining linguistic and conceptual paradigms, in order to account for the continuum we find in natural languages from free combining words to frozen expressions. In particular, we focus on the place of lexical and semantic restricted co-occurrences. From a processing viewpoint, we show how to generate/analyze syntagmatic expressions by using an efficient constraintbased processor, well fitted for a knowledge-driven approach. . | The Computational Lexical Semantics of Syntagmatic Relations Evelyne Viegas Stephen Beale and Sergei Nirenburg New Mexico State University Computing Research Lab Las Cruces NM 88003 USA viegas sb sergeiScrl.nmsu.edu Abstract In this paper we address the issue of syntagmatic expressions from a computational lexical semantic perspective.

This is why collocations should constitute an important part in the design of Machine Translation or Multilingual Generation systems. In this paper we address the issue of syntagmatic expressions from a computational lexical semantic perspective. From a representational viewpoint we argue for a hybrid approach combining linguistic and conceptual paradigms in order to account for the continuum we find in natural languages from free combining words to frozen expressions such as in idioms kick the proverbial bucket . In particular we focus on the representation of restricted semantic and lexical co-occurrences such as heavy smoker and professor . students respectively that we define later. From a processing viewpoint we show how to generate analyze syntagmatic expressions by using an efficient constraint-based processor well fitted for a knowledge-driven approach. In the following we first compare different approaches to collocations. Second we present our approach in terms of representation and .
