Frank MorawietzChart Parsing and Constraint Propagation7pp. PS (74kb), a longer Technical Report: 21pp., PS (126kb). AbstractIn this paper, parsing as deduction and constraint programming are brought together to outline a procedure for the specification of constraint-based chart parsers. Extending the proposal in Shieber et al. (1993) which provides a meta interpreter for several deduction systems, we show how to directly realize the inference rules for chart parsers as Constraint Handling Rules (Frühwirt 1998) by viewing the items of a conventional chart parser as constraints and the constraint base as a chart. This allows the direct use of the constraint resolution process to parse sentences.
