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).
- Over time, the original dataset diverged to two versions due to different pre-processing in recent publications: both have the same training set but their development and test sets differ. The Raw version has 82 questions in the development set and 100 questions in the test set; The Clean version (Wang and Ittycheriah et al. 2015, Tan et al. 2015, dos Santos et al. 2016, Wang et al. 2016) removed questions with no answers or with only positive/negative answers, thus has only 65 questions in the development set and 68 questions in the test set.
- Note: MAP/MRR scores on the two versions of TREC QA data (Clean vs Raw) are not comparable according to Rao et al. (2016).
