Learning-based Multi-Sieve Co-reference Resolution with Knowledge

  title={Learning-based Multi-Sieve Co-reference Resolution with Knowledge},
  author={Lev-Arie Ratinov and Dan Roth},
We explore the interplay of knowledge and structure in co-reference resolution. To inject knowledge, we use a state-of-the-art system which cross-links (or “grounds”) expressions in free text to Wikipedia. We explore ways of using the resulting grounding to boost the performance of a state-of-the-art co-reference resolution system. To maximize the utility of the injected knowledge, we deploy a learningbased multi-sieve approach and develop novel entity-based features. Our end system outperforms… CONTINUE READING
