| Abstract(in English) | Recently, Question-Answer(QA) systems using the WWW search engine have been developed by the spread of the Internet technology. These systems extract keywords from the question sentence and search the answer from retrieval results obtained by keywords on the WWW search engine. In this paper, We pay attention to the overdivision of the term when keywords are extracted from the question sentence, and propose the method to specify the term in the question sentence by WWW search engine. On this method, the concatenation level that uses the summary, the part of speech, and the character kind for each term candidate are extracted as the feature. And, This method specifies terms of term candidates by Support Vector Machine(SVM). Actually, Prom experimental resalts using 140 question sentences of NTCIR-QAC2, it was found that the accuracy of the term specific improved compared with the conventional method. |
