Grammar in 5D: The interface design of a mismatching grammar

Abstract

This chapter deals with grammar design, interfaces, mismatches and metatheory. The core question is: how can one describe and assess grammar design and, in particular, interface design? The distribution, derivation and direction of linguistic information being computed both between and within levels are hereby analysed in order to see how these parameters may combine in any theory of language modelling. More particularly, this chapter looks into the Functional Discourse Grammar framework and its hybrid approach to these features - non-derivational yet strongly directional - and advocates for a complete elimination of empty nodes in the search for a fully modular approach. This work further examines the architectural compatibility of Functional Discourse Grammar with various modular and constraint-based approaches with a strong lexical emphasis such as the Parallel architecture, autolexical Syntax, Head-Driven Phrase Structure Grammar or Lexical Functional Grammar. accordingly, it argues for the following design features for the functional framework: an interface-based lexicon which links distinct types of fully encapsulated information by means of bi-directional interfaces within lexical entries and with the grammar proper; and unification for intra-level construal in the search for weaker directionality.
