A Treebank Query System Based on an Extracted Tree Grammar

Recent work has proposed the use of an extracted tree grammar as the basis for treebank analysis and search queries, in which queries are stated over the elementary trees, which are small chunks of syntactic structure. However, this work was lacking in two crucial ways. First, it did not allow for including lexical properties of tokens in the search. Second, it did not allow for using the derivation tree in the search, describing how the elementary trees are connected together. In this work we describe an implementation that overcomes these problems.
