The corresponding Entrez Gene ID of each human gene mention,
Species information of each gene mention,
Gene full name/abbreviation pairs,
Co-reference of gene mentions, and
Sentence boundaries.
The IGN corpus intends to be released in the BioC XML format as a publicly available resources for other text mining systems.
