Parallel Multi-Theory Annotations of Syntactic Structure

Proceedings of the Sixth International Conference on Language Resources and Evaluation (LREC 2008)

Abstract

We present an approach to creating a treebank of sentences using multiple notations or linguistic theories simultaneously. We illustrate the method by annotating sentences from the Penn Treebank II in three different theories in parallel: the original PTB notation, a Functional Dependency Grammar notation, and a Government and Binding style notation. Sentences annotated with all of these theories are represented in XML as a directed acyclic graph where nodes and edges may carry extra information depending on the theory encoded.
