Abstract

Active constraints of the constraint logic programming paradigm allow (1) the reduction of the search space of programs and (2) a very concise representation of the problems. These two properties are particularly interesting for parsing problems: they can help us to reduce non-determinism and to use large coverage grammars. In this paper, we describe how to use such constraints for parsing ID/LP grammars and propose an implementation in Prolog III.
