BACKGROUND Biomedical semantic indexing is a very useful support tool for human curators in their efforts for indexing and cataloging the biomedical literature. OBJECTIVE The aim of this study was to describe a system to automatically assign Medical Subject Headings (MeSH) to biomedical articles from MEDLINE. METHODS Our approach relies on the assumption that similar documents should be cla...

BACKGROUND In traditional medicine, there has been a great deal of research on the effects exhibited by medicinal materials.

In recent years, numerous databases on medicinal materials and constituent compounds have been constructed. However, because these databases provi...

It is not news that medicine and other health care areas are changing. In recent years, physicians have been confronted with the challenge of the exponential increase in medical knowledge, as approximately two million articles are published annually in close to 23,000 biomedical journals. It is estimated that a general physician has to read 19 articles a day for 365 days each year to keep abrea...

The purpose of this article is to investigate the possibility of the automation of sophisticated subject indexing of medical journal articles. Approaches to subject descriptor assignment in information retrieval research are usually either based upon the manual descriptors included in the database or the attempted generation of alternative search parameters, using statistical, probabilistic or ...

BACKGROUND The COMET (Core Outcome Measures in Effectiveness Trials) Initiative is developing a publicly accessible online resource to collate the knowledge base for core outcome set development (COS) and the applied work from different health conditions. Ensuring that the database is as comprehensive as possible and keeping it up to date are key to its value for users. This requires the develo...

A systematic review of the literature on postherpetic neuralgia was performed. The authors identified studies using the National Library of Medicine's Medline database and Cochrane Library database. The authors determined absolute reduction rate, number needed to treat (NNT), 95% CI for NNT, and number needed to harm (NNH) for successful therapies of postherpetic neuralgia. Tricyclic antidepres...

Method: This study was conducted using scientific search engines such as Pubmed, Cinahl, Science Direct, Wiley Interscience, Ulakbim Medicine Database, and the Turkish Medline database. The English keywords were translated to “nursing by telephone” since that was the only term involved in the MeSH (Medical Subject Headings) index for English keywords and TST (Turkish Scientific Terms) for Turki...

DATA SOURCES The authors performed a systematic electronic search of MEDLINE, EMBASE, Med-Pilot, Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Cochrane Register of Controlled Trials, ClinicalTrials.gov, and Web of Science from database inception through January 17, 2011. No language restriction was applied. Reference lists and bibliographies of review articles relating ...
