Abstract
This paper proposes schematic changes to the TempEval framework that target the temporal vagueness problem. Specifically, two
elements of vagueness are singled out for special treatment: vague time expressions, and explicit/implicit temporal modification of events. As proof of concept, an annotation experiment on explicit/implicit modification is conducted on Amazon’s Mechanical Turk.
Results show that the quality of a considerable segment of the annotation is comparable to annotation obtained in the traditional double-blind setting, only with higher coverage. This approach offers additional flexibility in how the temporal annotation data can be used.
