A dependency structure interprets modification relationships between words and is often recognized as an important element in semantic information analysis. With conventional approaches for extracting this dependency structure, it is assumed that the complete sentence is known before the analysis starts. For spontaneous speech data, however, this assumption is not necessarily correct since sentence boundaries are not marked in the data and it is not easy to detect them correctly. Although sentence boundaries can be detected before dependency analysis, this cascaded implementation is not suitable for online processing since it delays the responses of the application. In this paper, we propose a sequential dependency analysis method for online spontaneous speech processing. The proposed method enables us to analyze incomplete sentences sequentially and detect sentence boundaries simultaneously. The analyzer can be trained using parsed data based on the maximum entropy principle. Experimental results using spontaneous lecture speech from the Corpus of Spontaneous Japanese show that our proposed method achieves online processing with an accuracy equivalent to that of offline processing in which boundary detection and dependency analysis are cascaded. |
