A binding rule for government-binding parsing

In this paper I propose a Binding rule for the identification of pronoun and anaphor referents in phrase-structure trees, assuming the general framework of lhe Government-binding theory outlined by Chom,;ky (1981). The Binding rule, specified by means of an attribute grammar, is a particular instantiation of the Free Indexing rule and binding axioms in Chomsky's Binding theory, with certain empirical and practical advantages. The complexities of the Binding rule proposed, as well as that inherent in Chomsky's Binding theory, are studied, and it i~ shown that the new rule is more psychologically plausible and cornputationally efficient than the original theory on wtfich it is based. The fragment of the attribute grammar shown here is part of an English grammar and parser being developed in tile Prolog and PLNLP languages.
