An Improved Oracle for Dependency Parsing with Online Reordering

Joakim Nivre, Marco Kuhlmann, and Johan Hall. An Improved Oracle for Dependency Parsing with Online Reordering. In Proceedings of the 11th International Conference on Parsing Technologies (IWPT), pages 73–76, Paris, France, 2009.

Abstract

We present an improved training strategy for dependency parsers that use online reordering to handle non-projective trees. The new strategy improves both efficiency and accuracy by reducing the number of swap operations performed on non-projective trees by up to 80%. We present state-of-the-art results for five languages with the best ever reported results for Czech.
