We propose a method to generate large-scale encyclopedic knowledge, which is valuable for much NLP research, based on the Web. We first search the Web for pages contain- ing a term in question. Then we use lin- guistic patterns and HTML structures to ex- tract text fragments describing the term. Fi- nally, we organize extracted term descrip- tions based on word senses and domains. In addition, we apply an automatically gener- ated encyclopedia to a question answering system targeting the Japanese Information- Technology Engineers Examination.
