"Our team from Atypon and the Aristotle University of Thessaloniki is honored to be recognized as winners in the 2013 BioASQ challenge. Outperforming PubMed's own MTI system in MeSH indexing was quite an achievement. We are proud to participate in BioASQ events, and we look forward to more challenges where we can hone our semantic indexing expertise and find ways to improve biomedical experts’ access to research information."
