The NLM Indexing Initiative

The NLM Medical Text Indexer System for Indexing Biomedical Literature

In the face of a growing workload and dwindling resources, the US National Library of Medicine (NLM) created the Indexing Initiative project in the mid-1990s. This cross-library team’s mission is to explore indexing methodologies that can help ensure that MEDLINE and other NLM document collections maintain their quality and currency and thereby contribute to NLM’s mission of maintaining quality...

Recent Enhancements to the NLM Medical Text Indexer

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...

The NLM Indexing Initiative: Current Status and Role in Improving Access to Biomedical Information

12 years on – Is the NLM medical text indexer still useful and relevant?

Gene Indexing: Characterization and Analysis of NLM's GeneRIFs

We present an initial analysis of the National Library of Medicine's (NLM) Gene Indexing initiative. Gene Indexing occurs at the time of indexing for all 4600 journals and over 500,000 articles added to PubMed/MEDLINE each year. Gene Indexing links articles about the basic biology of a gene or protein within eight model organisms to a specific record in the NLM's LocusLink database of gene prod...
