Revision as of 14:04, 24 March 2009

  • Microsoft Research Paraphrase Corpus (MSRP)
  • see Dolan, Quirk, and Brockett (2004)
  • train: 4,076 sentence pairs (2,753 positive: 67.5%)
  • test: 1,725 sentence pairs (1,147 positive: 66.5%)


Sample data

  • Sentence 1: Amrozi accused his brother, whom he called "the witness", of deliberately distorting his evidence.
  • Sentence 2: Referring to him as only "the witness", Amrozi accused his brother of deliberately distorting his evidence.
  • Class: 1 (true paraphrase)


Table of results

Algorithm Reference Description Accuracy F
MCS Mihalcea et al. (2006) unsupervised combination of several word similarity measures 70.3% 81.3%
WDDP Wan et al. (2006) supervised dependency-based features 75.0% 73.0%
