Discriminative Information Retrieval for Question Answering Sentence Selection

EACL 2017 Tongfei ChenBenjamin Van Durme

We propose a framework for discriminative IR atop linguistic features, trained to improve the recall of answer candidate passage retrieval, the initial step in text-based question answering. We formalize this as an instance of linear feature-based IR, demonstrating a 34{\%}-43{\%} improvement in recall for candidate triage for QA...
