Question Answering Based on Temporal Inference

Question Answering Based on Temporal Inference

Answering questions that ask about temporal information involves several forms of inference. First, relations between events and temporal expressions need to be inferred, either in the question or in the answer. Second, semantic inference between events, entities and their definitions needs to be performed. Sometimes, semantic inference employs aspectual information to relate events expressed b...

Temporal Information Extraction for Temporal Question Answering

This paper outlines work-in-progress regarding temporal information extraction, and highlights issues to be discussed by future research in temporal question answering. Based on Schilder & Habel (2001), we first present a semantic tagging system for temporal expressions and discuss how the temporal information conveyed by these expressions can be extracted. We then discuss extensions to the tem...

Investigating Embedded Question Reuse in Question Answering

The investigation presented in this paper is a novel method in question answering (QA) that enables a QA system to gain performance through reuse of information in the answer to one question to answer another related question. Our analysis shows that a pair of question in a general open domain QA can have embedding relation through their mentions of noun phrase expressions. We present methods f...
