Unification grammars are widely accepted as an expressive means for describing the structure of natural languages. In general, the recognition problem is undecidable for unificati...
The fundamental Quality of Service (QoS) routing problem, which consists in determining paths subject to multiple QoS constraints, has been extensively investigated in the intra-do...
Abstract. This article describes an attempt to implement a constraintbased dependency grammar for Czech, a language with rich morphology and free word order, in the formalism Exten...

In this paper we consider general path constraints for semistructured databases. Our general constraints do not suffer from the limitations of the path constraints previously stud...
