Using AnsProlog with Link Grammar and WordNet for QA with Deep Reasoning

Luis Tari and Chitta Baral

Early question and answering (QA) systems focused on keyword search among documents for answers. However, such systems can only answer fact-based questions. It becomes clear that to answer more sophisticated questions, QA systems should rely on some domain knowledge. We propose a question and answering system that uses AnsProlog to represent and reason from the knowledge extracted by using Link Grammar and WordNet.
