Dependency parsing with undirected graphs

2012

Abstract We introduce a new approach to transitionbased dependency parsing in which the parser does not directly construct a dependency structure, but rather an undirected graph, which is then converted into a directed dependency tree in a post-processing step. This alleviates error propagation, since undirected parsers do not need to observe the single-head constraint.

A Transition-Based Dependency Parser Using a Dynamic Parsing Strategy

2013

We present a novel transition-based, greedy dependency parser which implements a flexible mix of bottom-up and top-down strategies. The new strategy allows the parser to postpone difficult decisions until the relevant information becomes available. The novel parser has a 12% error reduction in unlabeled attachment score over an arc-eager parser, with a slow-down factor of 2.8.
