A Uniform Approach to Underspecification and Parallelism

Proceedings of the 35th Annual Meeting of the Association of Computational Linguistics (ACL), pp. 410-417, 1997

We propose a unified framework in which to treat semantic underspecification and parallelism phenomena in discourse. The framework employs a constraint language that can express equality and subtree relations between finite trees. In addition, our constraint language can express the equality up-to relation over trees which captures parallelism between them. The constraints are solved by context unification. We demonstrate the use of our framework at the examples of quantifier scope, ellipses, and their interaction.
