Overview
Overview
The identification of coreferential expressions, that is, expressions in text referring to the same thing, is important for many applications relying on the analysis of the meaning of statements in text. The GENIA Coreference corpus provides coreference annotations covering all the 1999 abstracts of the primary GENIA corpus.
The coreference annotation was produced by MedCo Annotation Project. The format conversion into GENIA format, and minor bug fixes were made by the GENIA Project.
