CRITAC—An experimental system for Japanese text proofreading

This paper describes an experimental expert system for proofreading Japanese text. The system is called CRITAC (CRITiquing using ACcumulated knowledge). It can detect typographical errors, Kana-to-Kanji conversion errors, and stylistic errors in Japanese text. We describe the basic concepts and features of CRITAC, including preprocessing of text, a high-level text model, Prolog-coded heuristic proofreading knowledge, and a user-friendly interface. Although CRITAC has been primarily designed for Japanese text, it appears that most of the concepts and the architecture of CRITAC can be applied to other languages as well.
