Title A Debug Tool For Practical Grammar Development
Venue Annual Meeting of the Association of Computational Linguistics
Session System Demonstration
Year 2003

We have developed willex, a tool that helps grammar developers to work effi- ciently by using annotated corpora and recording parsing errors. Willex has two major new functions. First, it decreases ambiguity of the parsing results by com- paring them to an annotated corpus and removing wrong partial results both au- tomatically and manually. Second, willex accumulates parsing errors as data for the developers to clarify the defects of the grammar statistically. We applied willex to a large-scale HPSG-style grammar as an example.
