Abstract

Dominance constraints are widely used in computational linguistics as a language for talking and reasoning about trees. In this paper, we extend dominance constraints by admitting set operators. We present a solver for dominance constraints with set operators, which is based on propagation and distribution rules, and prove its soundness and completeness. From this solver, we derive an implementation in a constraint programming language with finite sets and prove its faithfullness.
