| Abstract(in English) | We propose a method of extracting descriptions about a person from text by machine larning. It is intended to be utilized in the question-answering about person. This method is based on a multistage system that consists of two types of classifiers. The earlier classifier judges whether each passage includes description about a person or not. The later one decided the exact extent of the description in passages extracted by the earlier classifier. The experimental result shows that the proposed method is more accurate than the one-staged chunking method based on the labeling on a sentence sequence. |
