5 Conclusion and Future Work
</SectionTitle>
    <Paragraph position="0"> We developed a debug tool, willex, which uses XML tagged corpora and outputs information of grammar defects. By using tagged corpora, willex succeeded to reduce human workload. And by recording grammar defects, it provides debugging environment with a bigger perspective. But there remains a problem that a simple POS/label conversion table is not enough to resolve conflicts of a debugged grammar and a grammar assumed by tags. The tool should support to handle the complicated conflicts.</Paragraph>
    <Paragraph position="1"> In the future, we will try to modify willex to infer causes of parsing errors (semi-)automatically. It is difficult to find a point of parsing failure automatically, because subsentences that have no correspondent partial results are not always the failed point. Hence, we will expand willex to find the longest subsentences that are parsed successfully. Words, POS/labels and features of the subsentences can be clues to infer the causes of parsing errors.</Paragraph>
