Abstract

We aim to construct an academic writing assistance system for learners of Japanese as a second language who are tasked with writing academic papers and reports during the course of their studies. We propose to provide suggestions for rewriting inappropriate expressions within learner compositions using a dictionary and a method of comparing learner composition text data to authentic corpus data.From among many possible language elements, this paper focuses on defining connective expressions and the construction of a connectives expression dictionary. Beginning with a definition of connectives based on their role in text, we select 568 connective expressions using a combination of manual selection and automated extraction, and demonstrate the importance of the automatic approach as well as its weaknesses.Next, we manually annotate the connective expressions with ratings on their suitability to be used in the academic register. Finally, we show the possibilities of the resulting connectives dictionary in providing guidance to learners in the appropriate selection of connective expressions within the academic register.

我々は日本語を第二言語とする日本語学習者が大学などで論文・レポートなどアカデミックな文章を作成する作文支援システム構築を目指している.オーセンティックな大規模日本語コーパスを利用して,学習者の作文中の表現と,コーパス中の表現とを比較できる「表現辞典」を構築し,学習者の表現をその目的にふさわしい表現に言い換える提案をするものである.本稿では様々な言語要素の中から,「接続表現」に焦点を当て,「接続表現辞典」構築を目指す.はじめに文章全体を見据えた視点から「接続表現」という語を定義した後,大規模コーパスのテキストデータから人手とシステムの両方の方法で「接続表現」568項目を選定し,自動判定の必要性と問題点を述べた.最後に「接続表現」568項目からレジスター判定を人手で行い,学習者が目的とする論文にふさわしい表現が「接続表現辞典」の構築によって獲得できる可能性を示した.
