Goals
Paraphrase-Driven Open-Domain Question Answering Answer noisy user questions by generalizing from a question-paraphrase corpus.
Work Log
Oct 9
Discussed with Tony:
- Paraphrase module:
- New paraphrase template PMI scores are now based on more accurate template co-occurrence counts, and a minimum frequency of 50 was set for templates.
- Template language model (LM) trained based on n-grams from the lemmatized question corpus.
- Ideas for upcoming template classifier - Features for PMI, LM, pos-tag pattern, and leveraging the paraphrase corpus for unsupervised learning
- Answer Ranking
- AnswerDerivation ordering (baseline) ranking
- Strategies for training answer ranking function:
- Uniform sample of answers from representative questions?
- Use answers given in WikiAnswers for unsupervised learning?
Current Goals:
- Produce set of training (Q,A) pairs for hand-labeling from a uniform sample of answers over training questions.
- Explore feasibility of self-labeling data from answers given in WikiAnswers.
