| Abstract: | TempEval is a framework for evaluating systems that automatically annotate texts with temporal relations. It was created in
the context of the SemEval 2007 workshop and uses the TimeML annotation language. The evaluation consists of three subtasks
of temporal annotation: anchoring an event to a time expression in the same sentence, anchoring an event to the document creation
time, and ordering main events in consecutive sentences. In this paper we describe the TempEval task and the systems that
participated in the evaluation. In addition, we describe how further task decomposition can bring even more structure to the
evaluation of temporal relations.
