Abstract

In this paper we present a previously unexplored approach to recognizing the textual extent of temporal expressions. Based on the observation that temporal expressions are syntactic constituents, we use functional dependency relations between tokens in a sentence to determine which words in addition to a trigger word belong to the extent of the expression. This method is particularly attractive for the recognition of expressions with complex syntactic structure, for which state-of-the-art pattern-based taggers are not effective.
