In this paper, we experimentally evaluate two ranking methods and two selection methods. As for ranking, a dichotomy of unithood and termhood is a key notion. We evaluate these two notions experimentally by comparing Imp based ranking method that is based directly on termhood and C-value based method that is indirectly based on both termhood and unithood. As for selection, we compare the simple threshold method with the window method that we propose. We did the experimental evaluation with several Japanese technical manuals. The result does not show much difference in recall and precision. The small difference between the extracted terms by these two ranking methods depends upon their ranking mechanism per se.","subitem_description_type":"Abstract"}]},"item_11_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"99023","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakagawa, Hiroshi"}]}]},"item_11_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"John Benjamins Publishing Company"}]},"item_11_relation_9":{"attribute_name":"ISBN","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"9027249849","subitem_relation_type_select":"ISBN"}}]},"item_11_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"801","subitem_subject_scheme":"NDC"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中川, 裕志"}],"nameIdentifiers":[{"nameIdentifier":"99022","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":"2017-06-16"}],"displaytype":"detail","filename":"NAK.pdf","filesize":[{"value":"186.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NAK.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/43063/files/NAK.pdf"},"version_id":"289890f6-da42-4707-97dc-40cc5e7b3f6c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"automatic term extraction system","subitem_subject_scheme":"Other"},{"subitem_subject":"Computational Terminology","subitem_subject_scheme":"Other"},{"subitem_subject":"Japanese language","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":"book","resourceuri":"http://purl.org/coar/resource_type/c_2f33"}]},"item_title":"Experimental Evaluation of Ranking and Selection Methods in Term Extraction","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental Evaluation of Ranking and Selection Methods in Term Extraction"}]},"item_type_id":"11","owner":"1","path":["7447","7448"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-01-05"},"publish_date":"2012-01-05","publish_status":"0","recid":"43063","relation_version_is_last":true,"title":["Experimental Evaluation of Ranking and Selection Methods in Term Extraction"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:18:08.784909+00:00"}
