TAILIEUCHUNG - Báo cáo khoa học: "Partially Specified Signatures: a Vehicle for Grammar Modularity"

This work provides the essential foundations for modular construction of (typed) unification grammars for natural languages. Much of the information in such grammars is encoded in the signature, and hence the key is facilitating a modularized development of type signatures. We introduce a definition of signature modules and show how two modules combine. Our definitions are motivated by the actual needs of grammar developers obtained through a careful examination of large scale grammars. We show that our definitions meet these needs by conforming to a detailed set of desiderata. . | Partially Specified Signatures a Vehicle for Grammar Modularity Yael Cohen-Sygal Dept. of Computer Science University of Haifa yaelc@ Shuly Wintner Dept. of Computer Science University of Haifa shuly@ Abstract This work provides the essential foundations for modular construction of typed unification grammars for natural languages.

Such grammars are developed not only for purposes of theoretical linguistic research but also for natural language applications such as machine translation speech generation etc. Wide-coverage grammars are being developed for various languages Oepen et al. 2002 Hinrichs et al. 2004 Bender et al. 2005 King et al. 2005 in several theoretical frameworks . LFG Dalrymple 2001 and HPSG Pollard and Sag 1994 . Grammar development is a complex enterprise it is not unusual for a single grammar to be developed by a team including several linguists computational linguists and computer scientists. The scale of grammars is overwhelming for example the English resource grammar Copestake and Flickinger 2000 includes thousands of types. This raises problems reminiscent of those encountered in large-scale software development. Yet while software engineering provides adequate so lutions for the programmer no grammar development environment supports even the most basic needs such as grammar modularization combination of sub-grammars separate .
