However, typical computer systems require the user to change the text entry software each time a different language is used. This is cumbersome, especially when the languages change frequently. To solve this problem, we propose TypeAny, a novel multilingual text entry system that identifies the language of the user's key entry and automatically dispatches the input to the appropriate text entry system. This language identification is modeled as a hidden Markov model whose probability is estimated by using the PPM method. When evaluating this method, we obtained language identification accuracy of 96.7% when an appropriate language had to be chosen from among three languages. The number of control actions needed to switch languages was decreased 93% when using TypeAny rather than a conventional method.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"106281","nameIdentifierScheme":"WEKO"}],"names":[{"name":"EHARA, Yo"}]},{"nameIdentifiers":[{"nameIdentifier":"106282","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TANAKA-ISHII, Kumiko"}]}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"言語処理学会"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10472659","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13407619","subitem_source_identifier_type":"ISSN"}]},"item_2_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"007","subitem_subject_scheme":"NDC"}]},"item_2_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Association for Natural Language Processing"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学情報基盤センター"},{"subitem_text_value":"Department of Creative Informatics, Graduate School of Information Science and Technology, the University of Tokyo"},{"subitem_text_value":"東京大学大学院情報理工学系研究科創造情報学専攻"},{"subitem_text_value":"Graduate School of Information Science and Technology, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"江原, 遥"}],"nameIdentifiers":[{"nameIdentifier":"106279","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"田中, 久美子"}],"nameIdentifiers":[{"nameIdentifier":"106280","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":"2017-06-26"}],"displaytype":"detail","filename":"v15n5_08.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"v15n5_08.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/401/files/v15n5_08.pdf"},"version_id":"74f8a774-609c-4825-972e-e941900dd55a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"テキスト入力システム","subitem_subject_scheme":"Other"},{"subitem_subject":"多言語","subitem_subject_scheme":"Other"},{"subitem_subject":"言語判別","subitem_subject_scheme":"Other"},{"subitem_subject":"PPM","subitem_subject_scheme":"Other"},{"subitem_subject":"隠れマルコフモデル","subitem_subject_scheme":"Other"},{"subitem_subject":"Text entry system","subitem_subject_scheme":"Other"},{"subitem_subject":"Multilingual","subitem_subject_scheme":"Other"},{"subitem_subject":"Language identification","subitem_subject_scheme":"Other"},{"subitem_subject":"PPM","subitem_subject_scheme":"Other"},{"subitem_subject":"Hidden Markov model","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"TypeAny : 言語判別を用いた多言語入力システム","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"TypeAny : 言語判別を用いた多言語入力システム"}]},"item_type_id":"2","owner":"1","path":["15","104"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-08"},"publish_date":"2009-12-08","publish_status":"0","recid":"401","relation_version_is_last":true,"title":["TypeAny : 言語判別を用いた多言語入力システム"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:41:15.781831+00:00"}
