It is implemented in Prolog,ln the interests of rapid prototyping, but intended for later optimization. For development purposes we are using an existing corpus of i0,000 words of continuous prose from the PERQ's graphics documentation; in the long term,the system will be extended for use by technical writers in fields other than software, and possibly to other languages. At the time of writing, we have welldeveloped system development software, user interface, grammar and dictionary handling facilities, including dictionary entry in kanji, and a range of formats for output of linguistic representations and Japanese text. .
