Experiments of UNED at the third recognising textual entailment challenge

Abstract

This paper describes the experiments developed and the results obtained in the participation of UNED in the Third Recognising Textual Entailment (RTE) Challenge. The experiments are focused on the study of the effect of named entities in the recognition of textual entailment. While Named Entity Recognition (NER) provides remarkable results (accuracy over 70%) for RTE on QA task, IE task requires more sophisticated treatment of named entities such as the identification of relations between them.
