Abstract
While deductive parsing techniques are well-understood for traditional rule-based and lexicalist grammars, they are rather more elusive for current principle-based grammars. In this paper, we argue that a major source of difficulty arises from a fundamental difference in the way such grammars should be axiomatised. While rule-based grammars typically consist of a set of sufficient ‘structure-generating ’ axioms, principle-based grammars are more naturally expressed as a set of necessary ‘structure-licensing ’ conditions. On this basis we propose a methodology for implementing deductive parsers which is more suitable for this class of ‘licensing grammars’. We then argue that current principle-based grammatical theories can be most naturally implemented by decomposing them into representationally homogeneous subsystems, which are axiomatised as licensing ‘sub-grammars ’ – each contributing its own aspect of a global syntactic deduction system. Finally we consider the new range of options this approach offers for developing flexible and possibly distributed control regimes. 1
