This interface provides on-line access to JACY, an HPSG-based grammar of Japanese.

• You can input one sentence at a time, analyze it using Jacy, visualize analysis results in various forms and generate from a semantic representation.
• Text is segmented using ChaSen.
• Jacy has a vocabulary of around 48,000 words, but not so many proper names.

This demonstration uses facilities of the (a) Linguistic Knowledge Builder (LKB) grammar engineering platform, (b) high-efficiency PET System parser and (c) the [incr tsdb()] profiling environment.

The demonstrator uses CSS and (some) JavaScript. Please relay bug reports and suggestions for improvement back to the Jacy developers.
