Controllable Decontextualization of Yes/No Question and Answers into Factual Statements

Lingbo Mo, Besnik Fetahu, Oleg Rokhlenko, Shervin Malmasi

Abstract: Yes/No or polar questions represent one of the main linguistic question categories. They consist of a main interrogative clause, for which the answer is binary (assertion or negation). Polar questions and answers (PQA) represent a valuable knowledge resource present in many community and other curated QA sources, such as forums or e-commerce applications. Using answers to polar questions alone in other contexts is not trivial. Answers are contextualized, and presume that the interrogative question clause and any shared knowledge between the asker and answerer are provided.
