Survey of Systems for Implementing HPSG Gramamrs

814

Abstract

In this report, we present an overview of some chosen grammar development systems which could be applied to implement HPSG grammars. The selection contains descriptions of the following systems: TFS, CUF, ALE, ALEP, PAGE, ProFIT, Cl_ONE and ConTroll. We describe these systems with respect to the following criteria: the kind of type system used and its expressiveness, in particular the possibility to encode a type inheritance hierarchy; the constraint system employed; the expressiveness of the description language (disjunction, negation, LP rules, etc.) and built-in data types, e.g., sets; availability of lexical rules; declarativity of grammar description; the possibility to influence the computation rule, i.e, control mechanisms; system time performance on example grammars; system architecture: PS rules, built in parsers/generators, morphology components, etc.; foreign language interface, grammar tracing and debugging tools, graphical user interface, modular grammar development; documentation and support. The last section of the report presents a detailed comparison of the systems.
