Grammar Engineering for the Next Millenium

چکیده
The prevailing current view of a (symbolic, computational) grammar is basically that of a set of rewriting rules using feature-structured categories. However, whenever such a grammar is aimed at development of a realworld applied project, at least two disadvantages become clear. First, it breaks with the traditional understanding of a grammar as a network of phenomena (such as agreement, subcategorization, etc.), thus impeding the (direct) incorporation of this knowledge into such grammars. Second, a realistic grammar is inevitably huge and simultaneously contains very complex interdependencies among rules. This makes any modularization of grammar engineering (aka division of labour within a team) and above all maintaining and debugging realistic grammars a virtually impossible task. This paper presents an alternative view of formal (computational) grammars of natural language allowing for smooth modularization of the grammar-writing process and hence for meeting the pressing task of distributed grammar-development. The examples of both problems and their solutions are related to grammars in HPSG style, however, the problems discussed are in no way HPSGspecific, just on the contrary, they indeed concern any approach making use of featurestructured categories.
