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 rela- tions between finite trees. In addition, our constraint language can express the equal- ity up-to relation over trees which cap- tures parallelism between them. The con- straints are solved by context unification. We demonstrate the use of our framework at the examples of quantifier scope, ellipsis, and their interaction.
