Word-level Dependency-structure Annotation to Corpus of Spontaneous Japanese and its Application
Kiyotaka Uchimoto, Yasuharu Den · 2008
In Japanese, the syntactic structure of a sentence is generally represented by the relationship between phrasal units, bunsetsus in Japanese, based on a dependency grammar.In many cases, the syntactic structure of a bunsetsu is not considered in syntactic structure annotation.This paper gives the criteria and definitions of dependency relationships between words in a bunsetsu and their applications.The target corpus for the word-level dependency annotation is a large spontaneous Japanese-speech corpus, the Corpus of Spontaneous Japanese (CSJ).One application of word-level dependency relationships is to find basic units for constructing accent phrases.
