ARKref: a rule-based coreference resolution system
This is an incremental tool for researchers in natural language processing, providing a publicly available system for coreference tasks.
The paper presents ARKref, a deterministic rule-based system for noun phrase coreference resolution that uses syntactic and semantic information, building on prior work from 2009 and released as open-source in 2011.
ARKref is a tool for noun phrase coreference. It is a deterministic, rule-based system that uses syntactic information from a constituent parser, and semantic information from an entity recognition component. Its architecture is based on the work of Haghighi and Klein (2009). ARKref was originally written in 2009. At the time of writing, the last released version was in March 2011. This document describes that version, which is open-source and publicly available at: http://www.ark.cs.cmu.edu/ARKref
