Model）を，原言語と目的言語の両言語を考慮するバイリンガルなシナリオに拡張した手法である．提案モデルでは，原言語の係り受け木における各品詞を隠れ状態とし，各隠れ状態は，原言語の単語とともに，対応する目的言語の単語をシンボルとして出力する．本稿では，原言語の単語と目的言語の単語を結合させて出力する「結合モデル」と，別々に出力する「独立モデル」を提案する．NTCIR-9の日英特許翻訳タスクにおける評価実験を通じて，提案手法により推定した日本語の品詞タグを使うことにより，forest-to-string翻訳システムの性能を改善できることを示す．また，独立モデルは，結合モデルが抱えるシンボルのスパースネス問題を解決し，既存の品詞を使う従来の翻訳よりもBLEUで1%以上性能を改善できることを示す．","subitem_description_type":"Other"}]},"item_2_description_8":{"attribute_name":"論文抄録(英)","attribute_value_mlt":[{"subitem_description":"This paper proposes a nonparametric Bayesian method for inducing Part-of-Speech (POS) tags in dependency trees to improve the performance of machine translation (MT). In particular, we extend the monolingual infinite tree model to a bilingual scenario: each hidden state (POS tag) of a source-side dependency tree emits a source word together with its aligned target word, either jointly (joint model), or independently (independent model). Evaluations of Japanese-to-English translation on the NTCIR-9 data show that our induced Japanese POS tags for dependency trees improve the performance of a forest-to-string MT system. Our independent model gains over 1 point in BLEU by resolving the sparseness problem introduced in the joint model.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1680","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1665","bibliographicIssueDates":{"bibliographicIssueDate":"2014-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"55"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
