We focus on the case that two keywords are input to web search engine. We think that the keywords input by users have a semantic relation. We try to improve retrieval accuracy by checking whether two keywords have a dependency relation in the candidate pages or not. We construct a filtering tool which accept output of an ordinary search engine and select plausible ones by checking dependency relation. We show an experimental evaluation of our method. As a result, we compared our method with ones using just direct dependency relation and showed to raise the precision and recall. Furthermore, the best 20 pages by our system contained about 1.5窶骭€2 more relevant pages than general search engines. Therefore, we could confirm the validity of our method.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"3404","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"3386","bibliographicIssueDates":{"bibliographicIssueDate":"2007-10-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"48"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"自然言語"}]},"weko_creator_id":"1"},"created":"2025-01-18T22:44:55.569641+00:00","id":9808,"links":{}}
