    <Paragraph position="0"> This paper introduced a new form of textual entailment, known as contextual entailment, which can be used to recognize scenario-relevant information in both the questions users ask and in the answers that automatic Q/A systems return. In addition to outlining a framework for recognizing contextual entailment in texts, we showed that contextual entailment information can signi cantly enhance the quality of answers returned by a Q/A system in response to users' questions about a particular scenario. In our evaluations, we found that using contextual entailment allowed Q/A systems to improve their accuracy by more than 10% overall.</Paragraph>
