</SectionTitle>
    <Paragraph position="0"> In this paper, we proposed a question answering system which uses an encyclopedia as a knowledge base. For this purpose, we reformalized our Web-based extraction method, and proposed a new statistical organization model to improve the quality of extracted data.</Paragraph>
    <Paragraph position="1"> Given a term for which encyclopedic knowledge (i.e., descriptions) is to be generated, our method sequentially performs a) retrieval of Web pages containing the term, b) extraction of page fragments describing the term, and c) organizing extracted descriptions based on domains (and consequently word senses).</Paragraph>
    <Paragraph position="2"> For the purpose of evaluation, we used as test questions the Japanese Information-Technology Engineers Examination, and found that our Web-based encyclopedia was comparable with an existing dictionary in terms of the application to question answering. In addition, by using the both resources the performance of question answering was further improved.</Paragraph>
