Benjamin Han, Donna Gates, and Lori Levin. Anchoring Temporal Expressions in Scheduling-related Emails. In Annotating, Extracting and Reasoning about Time and Events. Dagstuhl Seminar Proceedings, Volume 5151, pp. 1-11, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2005)


In this paper we adopt a constraint-based representation of time, Time Calculus (TC), for anchoring temporal expressions in a novel genre, emails. Email is sufficiently different from the most studied genre - newswire texts, and its highly under-specified nature fits well with our representation. The evaluation of our anchoring system shows that it performs significantly better than the baseline, and the result compares favorably with some of the closest related work.
