order to address the issue of quickly overviewing the distribution of the contents of the collection of blog posts, this paper proposes a framework of estimating a topic model, namely “a domain topic model”, which is a topic model estimated with the texts of Wikipedia entries extracted from the collection of blog posts. In this “domain topic model” of Wikipedia entries, each topic represents domains such as meteorology, astronomy, biology, energy, and industry, that are closely related to a query term, e.g., “global warming”. We compare the proposed approach of topic modeling with Wikipedia knowledge source and the standard topic modeling without Wikipedia knowledge source. Both topic modeling results have quite different nature and contribute to quickly overviewing the search result of blog posts in a quite complementary fashion.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"11","bibliographic_titles":[{"bibliographic_title":"研究報告データベースシステム（DBS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2012-11-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"11","bibliographicVolumeNumber":"2012-DBS-155"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
