Japanese dependency structure is usu- ally represented by relationships between phrasal units called bunsetsus. One of the biggest problems with dependency struc- ture analysis in spontaneous speech is that clause boundaries are ambiguous.

The quotations and inserted clauses are determined by using an SVM-based text chunking method that considers in- formation on morphemes, pauses, fillers, etc. The information on automatically an- alyzed dependency structure is also used to detect the beginning of the clauses.
