To search for valuable information from this huge database are increasing needs from users. Search engines are playing as gateways for users to acquire useful information. Among requests of users to search engines, a certain amount of requests are to search for information related to people. However, since a personal name is often shared by several people, search results for a personal name query tend to contain documents relevant to several people. In our research, we tried to disambiguate names of people in the results from search engines. We proposed to use web directories as additional information to improve the disambiguation performance. We used information from web directories to improve the extraction of contexts related to people in documents and to improve the name disambiguation performance. We carried experiments with several well known web directories to disambiguate real documents containing ambiguous names. The experiment results showed that our approaches extracted contexts of people effectively and performed better than other approaches that used the vector space model method and the named entity recognition method.","subitem_description_type":"Abstract"}]},"item_7_dissertation_number_26":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第23941号"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"6676","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ヴー, クァン ミン"}]}]},"item_7_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00002414","subitem_identifier_reg_type":"JaLC"}]},"item_7_select_21":{"attribute_name":"学位","attribute_value_mlt":[{"subitem_select_item":"doctoral"}]},"item_7_subject_13":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"548","subitem_subject_scheme":"NDC"}]},"item_7_text_22":{"attribute_name":"学位分野","attribute_value_mlt":[{"subitem_text_value":"Information Science and Technology (情報理工学)"}]},"item_7_text_24":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_value":"Department of Information and Communication Engineering, Graduate School of Information Science and Technology (情報理工学系研究科電子情報学専攻)"}]},"item_7_text_27":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_value":"博情第186号"}]},"item_7_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"大学院情報理工学系研究科電子情報学専攻"},{"subitem_text_value":"Graduate School of Information Science and Technology Department of Information and Communication Engineering The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Vu, Quang Minh"}],"nameIdentifiers":[{"nameIdentifier":"6675","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-31"}],"displaytype":"detail","filename":"48057401.pdf","filesize":[{"value":"975.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"48057401.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/2420/files/48057401.pdf"},"version_id":"6eeae5fd-a852-477b-a24c-7f88a37592d2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Name disambiguation","subitem_subject_scheme":"Other"},{"subitem_subject":"Web directories","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"A STUDY ON NAME DISAMBIGUATION USING WEB DIRECTORIES","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A STUDY ON NAME DISAMBIGUATION USING WEB DIRECTORIES"}]},"item_type_id":"7","owner":"1","path":["280","330"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-03-01"},"publish_date":"2012-03-01","publish_status":"0","recid":"2420","relation_version_is_last":true,"title":["A STUDY ON NAME DISAMBIGUATION USING WEB DIRECTORIES"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:44:12.903356+00:00"}
