A PROLOG Implementation of Government-Binding Theory

A number of recent research efforts have explicitly grounded parser design on linguistic theory (e.g., Bayer et al. (1985), Berwick and Weinberg (1984), Marcus (1980), Reyle and Frey (1983), and Wehrli (1983)). Although many of these parsers are based on generative grammar, and transformational grammar in particular, with few exceptions (Wehrli (1983)) the modular approach as suggested by this theory has been lagging (Barton (1984)). Moreover, Chomsky (1986) has recently suggested that rule-based parsers are implausible and that parsers could be based on lexical properties and structure determining principles.
