Abstract

The query language in TIGERSearch is limited due to its lack of universal quantification. This restriction makes it impossible to ask simple queries like „Find sentences that do not include a certain word”. We propose an easy way to formulate such queries. We have implemented this extension to the query language in a tool that allows querying parallel treebanks including their alignment constraints. Our implementation of universal quantification relies on the view of node sets rather than single node unification. Our query tool is freely available.
