Temporal information extraction for temporal question answering
Frank Schilder, Christopher U. Habel · 2003
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 temporal tagger currently being implemented. 1.
