CoRTE: A Corpus of Recognizing Textual Entailment Data Annotated for Coreference and Bridging Relations

This paper presents CoRTE, an English corpus annotated with coreference and bridging relations, where the dataset is taken from the main task of recognizing textual entailment (RTE). Our annotation scheme elaborates existing schemes by introducing subcategories. Each coreference and bridging relation has been assigned a category. CoRTE is a useful resource for researchers working on coreference and bridging resolution, as well as recognizing textual entailment (RTE) task. RTE has its applications in many NLP domains. CoRTE would thus provide contextual information readily available to the NLP systems being developed for domains requiring textual inference and discourse understanding. The paper describes the annotation scheme with examples. We have annotated 340 text-hypothesis pairs, consisting of 24,742 tokens and 8,072 markables.
