Adapting a polar question to a form answerable by a non-polar question answering system. Entities are identified in the polar question. A set of non-polar questions are generated by removing an entity and using the remaining entities to form a set of questions with the removed entities as the expected answers. The set of non-polar questions are presented to a non-polar question answering system, and a set of answers are received. The set of answers are scored to determine a polar answer to the polar question.
