MTI is the main product of the Indexing Initiative project and has been providing indexing recommendations based on the Medical Subject Headings (MeSH®) vocabulary since 2002. In 2011, NLM expanded MTI's role by designating it as the first-line indexer (MTIFL) for a few journals; today the MTIFL workflow includes over 350 journals and continues to increase. The close collaboration of the NLM Index Section, Lister Hill National Center for Biomedical Communications, and Office of Computer & Communications Systems continues to expand and refine the ability of MTI to provide assistance to the indexers.
MTI provides recommendations to the NLM Indexers, MTIFL or MTI First Line indexing partially automates the standard indexing process at the US National Library of Medicine. MTIFL provides the initial indexing for a citation. A human indexer then reviews this indexing and modifies it as required by adding any missed terms, removing any incorrect terms, and supplying Publication Types. The process of the human curation of MTIFL results is called MTIFL Completion. The following link will take you to a more detailed description of MTIFL and a current list of the journals in the MTIFL program. MTIFL Webpage

This expanded version paper incorporates all of the material from our shorter 2013 BioASQ Workshop paper and also contains unpublished material providing a more comprehensive description of the MTI system.
There are several different ways to use MTI depending on your needs and how much data you have to process:
