An Ambiguity Aware Treebank Search Tool

Part of the Lecture Notes in Computer Science book series (LNCS, volume 7499)


We present a search tool for constituency treebanks with some interesting new features. The tool has been designed for a treebank containing several alternative trees for any given sentence, with one tree marked as the correct one. The tool allows to compare the selected tree with other candidates.

The query language is modelled after TIGER Search, but we extend the use of the negation operator to be able to use a class of universally quantified conditions in queries.

The tool is built on top of an SQL engine, whose indexing facilities provide for efficient searches.
