Comparative effectiveness research designs: an analysis of terms and coverage in Medical Subject Headings (MeSH) and Emtree.
OBJECTIVES We analyzed the extent to which comparative effectiveness research (CER) organizations share terms for designs, analyzed coverage of CER designs in Medical Subject Headings (MeSH) and Emtree, and explored whether scientists use CER design terms. METHODS We developed local terminologies (LTs) and a CER design terminology by extracting terms in documents from five organizations. We d...
متن کاملTwo Similarity Metrics for Medical Subject Headings (MeSH):
In the present paper, we have created and characterized several similarity metrics for relating any two Medical Subject Headings (MeSH terms) to each other. The article-based metric measures the tendency of two MeSH terms to appear in the MEDLINE record of the same article. The author-based metric measures the tendency of two MeSH terms to appear in the body of articles written by the same indi...
متن کاملTopic Models to Interpret MeSH – MEDLINE’s Medical Subject Headings
We show how topic models are useful for interpreting and understanding MeSH, the Medical Subject Headings applied to articles in MEDLINE. We show how our resampled author model captures some of the advantages of both the topic model and the author-topic model. We demonstrate how the topic modeling approach can provide an alternative and complementary view of the relationship between MeSH headin...
متن کاملBibliometric Perspectives on Medical Innovation using the Medical Subject Headings (MeSH) of PubMed
Multiple perspectives on the nonlinear processes of medical innovations can be distinguished and combined using the Medical Subject Headings (MeSH) of the Medline database. Focusing on three main branches—“diseases,” “drugs and chemicals,” and “techniques and equipment”—we use base maps and overlay techniques to investigate the translations and interactions and thus to gain a bibliometric persp...
متن کاملOn the Use of MeSH Headings to Improve Retrieval Effectiveness
Molecular biologists study the biochemical function, chemical structure and evolutionary history of genes and proteins from all types of organisms, from human beings to fruit flies and yeast [8, 3]. While molecular biologists still spend much of their time in wet labs, they nowadays often spend equally as much time in front of computers. Information has become a critical research tool, and seve...
