In the 2009 Recognizing Textual Entail-ment 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 pa-per focuses on some problematic issues related to resolving coreferences to enti-ties, space, time and events at the corpus level, as emerged during the annotation of the data set for the textual entailment Search Pilot.
