Resource sharing among HPSG and LTAG communitiesby a method of grammar conversion from FB-LTAG to HPSG

摘要

This paper describes the RenTAL system,which enables sharing resourcesin LTAG and HPSG formalisms by amethod of grammar conversion froman FB-LTAG grammar to a stronglyequivalent HPSG-style grammar. Thesystem is applied to the latest versionof the XTAG English grammar. Experimentalresults show that the obtainedHPSG-style grammar successfullyworked with an HPSG parser, andachieved a drastic speed-up against anLTAG parser. This system enables toshare not only grammars and lexiconsbut also parsing techniques.
