The versions of bio-ontologies and MEDLINE repository adopted in the indexing process are mentioned in the text. The Number of indexed terms of controlled vocabularies reported in this table are counted on indexing results of human related publications only so their numbers are smaller than those in our earlier work [2], which were counted on all species appeared in GeneRIF. The Number of terms in CV are counted on the vocabularies independently from the indexing process. The numbers of terms of Merge-9, Merge-4 and Concept-4 are counted on text mining results of all species occurring in GeneRIF.
