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": "\u5b66\u4f4d\u6388\u4e0e\u756a\u53f7", "attribute_value_mlt": [{"subitem_dissertationnumber": "\u7532\u7b2c23941\u53f7"}]}, "item_7_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "6676", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u30f4\u30fc, \u30af\u30a1\u30f3 \u30df\u30f3"}]}]}, "item_7_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15083/00002414", "subitem_identifier_reg_type": "JaLC"}]}, "item_7_select_21": {"attribute_name": "\u5b66\u4f4d", "attribute_value_mlt": [{"subitem_select_item": "doctoral"}]}, "item_7_subject_13": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "548", "subitem_subject_scheme": "NDC"}]}, "item_7_text_22": {"attribute_name": "\u5b66\u4f4d\u5206\u91ce", "attribute_value_mlt": [{"subitem_text_value": "Information Science and Technology (\u60c5\u5831\u7406\u5de5\u5b66)"}]}, "item_7_text_24": {"attribute_name": "\u7814\u7a76\u79d1\u30fb\u5c02\u653b", "attribute_value_mlt": [{"subitem_text_value": "Department of Information and Communication Engineering, Graduate School of Information Science and Technology (\u60c5\u5831\u7406\u5de5\u5b66\u7cfb\u7814\u7a76\u79d1\u96fb\u5b50\u60c5\u5831\u5b66\u5c02\u653b)"}]}, "item_7_text_27": {"attribute_name": "\u5b66\u4f4d\u8a18\u756a\u53f7", "attribute_value_mlt": [{"subitem_text_value": "\u535a\u60c5\u7b2c186\u53f7"}]}, "item_7_text_36": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Thesis"}]}, "item_7_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u5927\u5b66\u9662\u60c5\u5831\u7406\u5de5\u5b66\u7cfb\u7814\u7a76\u79d1\u96fb\u5b50\u60c5\u5831\u5b66\u5c02\u653b"}, {"subitem_text_value": "Graduate School of Information Science and Technology Department of Information and Communication Engineering The University of Tokyo"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Vu, Quang Minh"}], "nameIdentifiers": [{"nameIdentifier": "6675", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-05-31"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "48057401.pdf", "filesize": [{"value": "975.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 975500.0, "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": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "Name disambiguation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Web directories", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "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": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "A STUDY ON NAME DISAMBIGUATION USING WEB DIRECTORIES"}]}, "item_type_id": "7", "owner": "1", "path": ["9/233/280", "34/105/330"], "permalink_uri": "https://doi.org/10.15083/00002414", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_name_i18n": "\u516c\u958b\u65e5", "attribute_value": "2012-03-01"}, "publish_date": "2012-03-01", "publish_status": "0", "recid": "2420", "relation": {}, "relation_version_is_last": true, "title": ["A STUDY ON NAME DISAMBIGUATION USING WEB DIRECTORIES"], "weko_shared_id": null}
