Linguistic Data Consortium

DEFT Chinese and English Light and Rich ERE Parallel Annotation was developed by LDC and contains 179 Chinese discussion forum documents and their English translations annotated for entities, relations, and events (ERE). Light ERE annotation labels entity mentions for the target set of entity, relation and event types between and among those entities including coreference. Rich ERE annotation expands types and tagging in the entities, relations, and events annotation tasks and replaces strict event coreference with a more loosely defined event hopper annotation. 179 Chinese-English document pairs were annotated following Light ERE annotation guidelines; a subset of 171 Chinese-English document pairs were also labeled with Rich ERE annotation. The source data and English translations were drawn from BOLT Chinese Discussion Forum Parallel Training Data (LDC2017T05) originally collected and translated by LDC under the DARPA BOLT program https://catalog.ldc.upenn.edu/LDC2026T04
