CLP based HPSG Parsing
- Johannes Matiasek
- We describe a system for principle based parsing of HPSG employing constraint logic programming techniques. Typed features structures are implemented as constraints on PROLOG variables and are instantiated in a lazy fashion. Grammar principles as well as relational constraints are stated in a declarative way by means of conditional constraints on feature structures. The procedural interpretation given to these conditional constraints together with the data driven delay mechanism implemented yields efficient parsing behavior.
