5 Conclusion
</SectionTitle>
    <Paragraph position="0"> We described the RenTAL system, a grammar converter from FB-LTAG to HPSG. The grammar conversion guarantees the strong equivalence, and hence we can obtain an HPSG-style grammar equivalent to existing LTAG grammars. Experimental result showed that the system enabled to share not only LTAG grammars, but also HPSG parsing techniques. This system will enable a variety of resource sharing such as the sharing of the programming/grammar-development environment (Makino et al., 1998; Sarkar and Wintner, 1999) and grammar extraction methods from bracketed corpora (Xia, 1999; Chen and Vijay-Shanker, 2000; Neumann, 1998). Although our system connects only FB-LTAG and HPSG, we believe that our approach can be extended to other formalisms such as Lexical-Functional Grammar (Kaplan and Bresnan, 1982).</Paragraph>
    <Paragraph position="1"> Acknowledgment The authors are indebted to Mr. Anoop Sarkar for his help in using his parser in our experiment. The authors would like to thank anonymous reviewers for their valuable comments and criticisms on this paper.</Paragraph>
