Toward Expressing Generative Lexicon Using GraphXML

Abstract

Machine translation and inference engine need a way of representing the lexicons. The way should enumerate the semantic meanings of the lexicons and also express the compositional aspects of the meanings. Pustejovsky (1991,1995) proposed Generative Lexicon (GL) as a solution for this semantic enumeration and compositionality. Generative Lexicon has many semantic structures and semantic operations to capture the creative use of words in novel contexts and to explain the polymorphic nature of language. To use lexicons in machine translation and inference engine, the next step is building this Generative Lexicon in computational dictionary format. The lexicons are usually defined by several linguists, who cooperate in building the lexicons. Even if they work under the same Generative Lexicon, they may have different disciplines on enumerations and semantic constraints. Also they may not share the interest in computational inference modules working with the semantic constraints. There are needs both for flexible representations of lexicons which can merge different works of linguists and for describing the lexicons in independent and easily-transformable forms with inference engine.
