This paper proposes an extension of Dependency Tree Semantics (DTS), an underspecified logic originally proposed in [20], that uniformily im- plements constraints on Nested Quantification, Island Constraints and logical Redundancy. Unfortunately, this extension makes the complex- ity exponential in the number of NPs, in the worst cases. Nevertheless, we conducted an experiment on the Turin University Treebank [6], a Treebank of italian sentences annotated in a syntactic dependency for- mat, whose results seem to indicate that these cases are very rare in real sentences.
