In 2012, we introduced a Publications track that shows mapped DNA and protein sequences, SNPs, cytogenetic bands and gene symbols that have been text-mined from biomedical articles in Elsevier, PubMed Central and other databases (23). In the past year we have doubled the number of research articles to more than 5 million, and now classify them into different categories (disease related, protein structure, cis-regulatory, etc.) depending on their keyword content. The categories are differentiated by color in the display, which can be filtered by categories or publishers.
