In the 2009 Recognizing Textual Entailment challenge a Search Pilot task has been introduced, aimed at finding all the sentences in a corpus which entail a set of given hypotheses. The preparation of the data set for this task has provided an opportunity to better understand some phenomena concerning textual entailment recognition in a natural setting. This paper focuses on some problematic issues related to resolving coreferences to entities, space, time and events at the corpus level, as emerged during the annotation of the data set for the textual entailment Search Pilot.

Abstract
In the 2009 Recognizing Textual Entailment challenge a Search Pilot task has been introduced, aimed at finding all the sentences in a corpus which entail a set of given hypotheses. The preparation of the data set for this task has provided an opportunity to better understand some phenomena concerning textual entailment recognition in a natural setting. This paper focuses on some problematic issues related to resolving coreferences to entities, space, time and events at the corpus level, as emerged during the annotation of the data set for the textual entailment Search Pilot.File in questo prodotto:
