MeSH is one of the sources from which Monocl extracts and suggests indexed keywords.
What is MeSH?
MeSH is an abbreviation for Medical Subject Headings and is a keyword hierarchy administered by the National Library of Medicine (NLM) in the US. At the most general level of the hierarchical structure are very broad headings such as "Cancer" or "Mental Disorders." More specific keywords are found at more narrow levels of the twelve-level hierarchy, such as "Small Cell Lung Cancer" and "Schizophrenia."
There is a range of synonyms associated with a keyword e.g. "Cancer; Neoplasm; Tumor" - these are also included in Monocl. The MeSH hierarchy is updated on an annual basis to include new keywords. More information may be found at NLM's website.
Are these the same keywords that authors suggest to describe their own research?
Keywords are selected by qualified NLM staff based on research content. This is thus independent of what keywords an author may have proposed when the manuscript was submitted.
How is MeSH applied to publications?
The MeSH thesaurus is used by NLM for indexing articles from 5,400 of the world's leading biomedical journals for the MEDLINE®/PubMED® database. Each bibliographic reference is associated with a set of 10-15 MeSH terms that describe the content of the item. This process can take up to six months after a manuscript has been accepted for publication.
