Korean Syntactic Analysis Using Dependency Rules and Segmentation
Yong-uk Park, Hyuk‐Chul Kwon · 2008
This paper presents a Korean syntactic analysis system. This syntactic analyzer provides an adequate parsing method using the dependency rules and segmentation. We use dependency grammar for syntactic analysis. Dependency grammar is very useful for Korean syntactic analysis. But dependency grammar makes many ambiguities in Korean syntactic analysis system. We try to disambiguate for syntactic analysis system by the many dependency rules and segmentation. Segmentation is made during parsing. If two adjacent morphemes have no syntactic relations, our syntactic analyzer makes new segment between these two morphemes, and find out all possible partial parse trees of that segmentation and combine them into complete parse trees. Also we use adjacent-rule and adverb subcategorization to disambiguate of syntactic analysis. To eliminate the inadequate parse trees, we use the information of predicate argument.
