WordNet is one of the representative taxonomies and defines general terms, though it defines few named entities, specific terms and new words. On the other hand, Wikipedia, a large-scale free online encyclopedia, defines such terms and classifies them into a variety of categories. However, because the category structure is a network that allows multiple parents and loops, it is hard to determine whether a term belongs to a category or not. In this paper, we propose a method to probabilistically classify terms by analyzing Wikipedia category network based on graph theories. We also propose a text classification method using the result of probabilistic term classification and Naive Bayes. In the experiments on both Web snippet dataset and science news dataset, we confirmed the effectiveness of our method for classifying texts into several categories.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"63","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌データベース（TOD）"}],"bibliographicPageStart":"51","bibliographicIssueDates":{"bibliographicIssueDate":"2012-09-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"5"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:37:21.819531+00:00","id":85816,"links":{}}
