May 7, 2013: Recent improvements to the Stanford Deterministic Coreference Resolution System (Recasens et al., below) won the best short paper award at NAACL 2013. June 30, 2011: This system was the top ranked system at the CoNLL-2011 shared task. This system implements the multi-pass sieve coreference resolution (or anaphora resolution) system described in Lee et al. (CoNLL Shared Task 2011) and Raghunathan et al. (EMNLP 2010). The score is higher than that in EMNLP 2010 paper because of additional sieves and better rules (see Lee et al. 2011 for details). Mention detection is included in the package.
