Recent Enhancements to the NLM Medical Text Indexer

چکیده
The main goal of the US National Library of Medicine (NLM) Index ing Initiative is to explore indexing methodologies that may help the NLM In dexing staff keep pace with the ever increasing challenges of indexing over 700,000 MEDLINE citations each year using a vocabulary of over 27,000 MeSH Descriptors and 220,000 MeSH Supplementary Concept Records. The BioASQ Challenge has been a tremendous benefit by expanding our knowledge of other indexing systems, specifically the technologies used in those systems to identify relevant indexing for biomedical literature. This paper provides an up date on improvements to NLM’s Medical Text Indexer (MTI) functionality and performance since the first BioASQ Challenge. We have, in a limited way, ap plied some of the lessons learned from that first Challenge to MTI to assess what performance gains we might see. The research discussed at the 2013 Bi oASQ Challenge Workshop inspired us to make changes to MTI that have re sulted in a 2.69 (4.44%) increase in Precision and very little change in Recall.
