    Abstract

    The Korean Combinatory Categorial Grammar (KCCG) formalism can uniformly handle word order variation among arguments and adjuncts within a clause as well as in complex clauses and across clause boundaries, i.e., long distance scrambling. In this paper, incremental parsing technique of a morpheme graph is developed using the KCCG. We present techniques for choosing the most plausible parse tree using lexical information such as category merge probability, head-head co-occurrence heuristic, and the heuristic based on the coverage of subtrees. The performance results for various models for choosing the most plausible parse tree are compared. 1 Introduction Korean is a non-configurational, postpositional, agglutinative language. Postpositions, such as noun-endings, verb-endings, and prefinal verbendings, are morphemes that determine the functional role of NPs (noun phrases) and VPs (verb phrases) in sentences and also transform VPs into NPs or APs (adjective phrases). Since a sequence of...
