Outline of Final Research Achievements

In this study, the researcher digitized introductory engineering textbooks and collected engineering research journal articles and built a corpus of engineering text. From the corpus, the engineering keywords and their collocates were statistically extracted to create a database of field-specific keyword collocations. This was compared with a database created with collocation information based on the dependency-grammar. Since the statistical extraction needs preprocess of the data before storing on the database, and the databased based on the grammatical collocation information was found to be more useful, the final database was created with grammar-relationship collocations.

Academic Significance and Societal Importance of the Research Achievements

大学における英語学習は高学年時においては、すべてにおいて高いレベルを目指すよりも、分野ごとの語彙文法知識や特定のタスクをこなせる能力を身につけることが現実的である。特に専門分野の語彙に関しては、これまで専門用語の単語リスト作成などは行われてきたが、共起情報まで含めたものは多く見られなかった。それらを考慮したデータベースを作成し、学習に必要な共起語を抽出したり、論文作成時に、特定の語の共起語を検索できることは、大学生・大学院生のみならず、研究者に取っても有用なものであろう。
