Existing temporal relation (TempRel) annotation schemes often have low interannotator agreements (IAA) even between experts, suggesting that the current annotation task needs a better definition.… (More)

Extracting temporal relations (before, after, overlapping, etc.) is a key aspect of understanding events described in natural language. We argue that this task would gain from the availability of a… (More)
