Parallel Chinese-English Entities, Relations and Events Corpora.

This paper introduces the parallel Chinese- English Entities, Relations and Events (ERE) corpora developed by Linguistic Data Consortium under the DARPA Deep Exploration and Filtering of Text (DEFT) Program. Original Chinese newswire and discussion forum documents are annotated for two versions of the ERE task. The texts are manually translated into English and then annotated for the same ERE tasks on the English translation, resulting in a rich parallel resource that has utility for performers within the DEFT program, for participants in NIST's Knowledge Base Population evaluations, and for cross-language projection research more generally.
