Answering questions that ask about temporal information involves several forms of inference. In order to develop question answering capabilities that benefit from temporal inference, we believe that a large corpus of questions and answers that are discovered based on temporal information should be available. This paper describes our methodology for creating AnswerTime-Bank, a large corpus of qu...

In this paper we argue that access to rich semantic structures derived from questions and answers will enable both the retrieval of more accurate answers to simple questions and enable inference processes that explain the validity and contextual coverage of answers to complex questions. Processing complex questions involves the identifications of several forms of complex semantic structures. An...
