Abstract(in English) | In this paper, we propose a PCFG-based Japanese syntactic analysis using part-of-speech N-gram information. This method uses syntactic rules gathered from bracketed corpora and finds an optimal syntactic tree by calculating the occurrence probability obtained from the frequency information. The proposed grammar regards sequences of part-of-speech as clause markers. In this case, it is necessary to forecast occurrence probabilities of long or unseen clauses. N-gram information is used to estimate them, instead of clause-occurrence probabilities, to cope with this issue. Initial experimental results showed that our method achieved the same performance as the previous methods and provided robust processing of syntactic analysis. |
