Recovery of Japanese dependency structure using multiple pause information

Meirong Lu, Kazuyuki Takagi, Kazuhiko Ozeki

This paper is concerned with the problem of exploiting pause information for recovering dependency structures of read Japanese sentences. In our past work, two kinds of pauses were employed: post-phrase pause that immediately succeeds a phrase in question, and post-postphrase pause which immediately succeeds the phrase that follows a phrase in question. It was found that simultaneous use of two kinds of pause information improves the parsing accuracy compared to the case where only the post-phrase pause is used. In this paper, we employed yet another kind of pause (pre-phrase pause), which immediately precedes a phrase in question. By combining the three kinds of pause information appropriately, the parsing accuracy was further improved compared to the case where the post-phrase pause and the post-postphrase pause were used as in our previous work.
