Revision as of 13:04, 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% |
