Forty percent (391 of 973) of the MeSH concepts matched the manually attributed MeSH terms and 20% of manually assigned MeSH headings were not identified.
Assign headings to each main topic.
To enhance the discoverability of books, etc., catalogers assign subject headings, i.e. concepts and meaningful compound phrases taken from an official list.
The software also generates a keywords report at the scientist-year level, using the medical subject headings (MeSH) assigned by the National Library of Medicine to each publication indexed by MEDLINE.
For each domain, related enablers and barriers were grouped and relevant headings were assigned.
MEDLINE and Embase were searched using the search strategy: 'Diabetes Mellitus as the major subject heading, with the sub-heading 'Epidemiology' assigned (which includes incidence and prevalence), and restricted to publication years 1998 to 2003'.
Defining medical informatics literature as articles assigned "Medical Informatics" MeSH (Major Topic) headings by National Library of Medicine indexers may result in a more comprehensive analysis and more practical results for researchers.
We found that each MI-MeSH article in the study corpus was assigned between 1 and 27 MeSH headings as Major Topics.
Assign page numbers throughout the document, or if you prefer, assign numbers to the headings and sub-headings.
Figure 4 lists the 50 MI-MeSH headings as well as their frequency assigned as Major Topic over the 20 year period.
