Outline of Final Research Achievements

This research aims to develop natural language processing technologies to construct a formulaic expression database for English writing assistance. Focusing on academic paper writing, we proposed a method for extracting and retrieving formulaic expressions with their communicative functions. We also constructed an annotated corpus of sentences with communicative functions that can be used to training and evaluating. Our research demonstrated the effectiveness of deep learning models in extracting communicative functions and grammatical knowledge in extracting formulaic expressions.

Academic Significance and Societal Importance of the Research Achievements

英語による文書作成を支援するための定型表現集が数多く出版されているが、その大半は電子化されておらず、電子化されていたとしても執筆途中に必ずしも気軽に利用できるものではない。本研究では、体系化された定型表現を大規模なドメイン・コーパスに対応付けることによって、ドメインに特化した言い回しや伝達機能などを含む豊富な文脈情報が獲得できることを示した。本研究で得られた知見は、これまで困難であった定型表現の予測や検索の実現に結び付くものである。
