Answer Sentence Selection
The task of answer sentence selection is designed for the open-domain question answering setting. Given a question and a set of candidate sentences, the task is to choose the correct sentence that contains the exact answer and can sufficiently support the answer choice.
- QA Answer Sentence Selection Dataset: labeled sentences using TREC QA track data, provided by Mengqiu Wang and first used in Wang et al. (2007).
| Algorithm | Reference | MAP | MRR |
|---|---|---|---|
| Punyakanok (2004) | Wang et al. (2007) | 0.419 | 0.494 |
| Cui (2005) | Wang et al. (2007) | 0.427 | 0.526 |
| Wang (2007) | Wang et al. (2007) | 0.603 | 0.685 |
| H&S (2010) | Heilman and Smith (2010) | 0.609 | 0.692 |
| W&M (2010) | Wang and Manning (2010) | 0.595 | 0.695 |
| Yao (2013) | Yao et al. (2013) | 0.631 | 0.748 |
| S&M (2013) | Severyn and Moschitti (2013) | 0.678 | 0.736 |
| Shnarch (2013) - Backward | Shnarch (2013) | 0.686 | 0.754 |
| Yih (2013) - LCLR | Yih et al. (2013) | 0.709 | 0.770 |
