  Indexing Initiative > MetaMapped MEDLINE Baseline
MetaMap is a highly configurable program that maps biomedical text to concepts in the UMLS® Metathesaurus®. MetaMap also forms the core of the Indexing Initiative Project suite of programs, and is the basis for one of the indexing methods in the NLM Indexing Initiative's Medical Text Indexer (MTI). For more information on MetaMap and the Indexing Initiative Project, please see the Indexing Initiative Homepage and MetaMap Homepage web pages.

If you would prefer Human Readable or XML formatting for your results, we do have a program called MM_Print which is available for download so you can convert the MMO results into the format you want. The download is available from the following web page: https://metamap.nlm.nih.gov/MMPrint.shtml


Between March 25, 2015 and April 5, 2015 we processed all 779 files with 23,343,329 citations from the 2015 Medline®/PubMed® Baseline through the MetaMap program generating MetaMap Machine Output (MMO) formatted results for each of the citations. The results are now available via the following link. You have the option of downloading the 779 individual result files, or there is a single tar file called 2015.tar which contains all of the result files.
