Since a word's sense depends on the context, such as surrounding words, similar words are believed to have similar sets of surrounding words. Therefore, we predict target word senses by calculating Euclidean distances between the target words' surrounding word vectors and their synonyms using word embeddings. In addition, we replace word tokens in the corpus with their concept tags, that is, article numbers of the Word List by Semantic Principles using prediction results. After that, we create concept embeddings with the concept tag sequence and predict the senses of the target words using the distances between surrounding word vectors, which consist the word and concept embeddings. This paper shows that concept embedding improved the performance of Japanese All-words WSD.","subitem_description_type":"Other"}]},"item_10001_description_5":{"attribute_name":"抄録","attribute_value_mlt":[{"subitem_description":"all-words 語義曖昧性解消（以下 all-words WSD (word sense disambiguation)）とは文書中のすべての単語の語義ラベルを付与するタスクである．単語の語義は文脈，すなわち周辺の単語によって推定でき，周辺の単語同士が類似している場合中心の単語同士の語義も類似していると考える．そこで本研究では，対象単語とその類義語群から周辺単語の分散表現を作成し，ユークリッド距離を計算することで対象単語の語義を予測した．また，語義の予測結果をもとにコーパスを語義ラベル列に変換し，語義の分散表現を作成した．語義の分散表現を用いて周辺単語ベクトルを作成し直し，再び語義の予測を行った．コーパスには分類語彙表番号がアノテーションされた『現代日本語書き言葉均衡コーパス』(BCCWJ) を利用した．本研究では分類語彙表における分類番号を語義とし，類義語も分類語彙表から取得した．本研究では，提案手法とランダムベースライン，Pseudo Most Frequent Sense (PMFS)，Yarowsky の手法，LDAWN を比較し，提案手法が勝ることを示した．","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"言語処理学会"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.5715/jnlp.26.361","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1340-7619","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"2185-8314","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"鈴木, 類"},{"creatorName":"スズキ, ルイ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"古宮, 嘉那子"},{"creatorName":"コミヤ, カナコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"浅原, 正幸"},{"creatorName":"アサハラ, マサユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐々木, 稔"},{"creatorName":"ササキ, ミノル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"新納, 浩幸"},{"creatorName":"シンノウ, ヒロユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, Rui","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Komiya, Kanako","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Asahara, Masayuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sasaki, Minoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shinnou, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-10-17"}],"displaytype":"detail","filename":"jnlp_26_361.pdf","filesize":[{"value":"807.1 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"jnlp_26_361.pdf","url":"https://repository.ninjal.ac.jp/record/2255/files/jnlp_26_361.pdf"},"version_id":"472fb469-05e7-4bf4-9931-aa6d763adbda"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"all-words","subitem_subject_scheme":"Other"},{"subitem_subject":"語義曖昧性解消","subitem_subject_scheme":"Other"},{"subitem_subject":"分類語彙表","subitem_subject_scheme":"Other"},{"subitem_subject":"分散表現","subitem_subject_scheme":"Other"},{"subitem_subject":"All-words","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Word Sense Disambiguation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Word List by Semantic Principles","subitem_subject_language":"en","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":"概念辞書の類義語と分散表現を利用した教師なし all-words WSD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"概念辞書の類義語と分散表現を利用した教師なし all-words WSD"},{"subitem_title":"Unsupervised All-words WSD Using Synonyms and Embeddings","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["324"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-10-17"},"publish_date":"2019-10-17","publish_status":"0","recid":"2255","relation_version_is_last":true,"title":["概念辞書の類義語と分散表現を利用した教師なし all-words WSD"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T14:45:07.211952+00:00"}
