What is the difference between pubmed and web of science

But no figures no columns were labeled or illustrated the idea of the paper. Discussion: The citation and the period of time covered by each site , the country of origin are the main variants , discussed with multiple angles. The conclusion supported supported by the mentioned references as well as the results.

Having said that we have to emphasize the important limitations of the study namely the number of the sites , alot of other sites should be involved as the-research gate , the publons and the idex. Also the variants were not enough to analyze. Log in. Web of Science. Identifiers publons. Navigate Abstract. Post-pub review, Dec Publication History. Abstract The evolution of the electronic age has led to the development of numerous medical databases on the World Wide Web, offering search facilities on a particular subject and the ability to perform citation analysis.

Authors Falagas, Matthew E. Chart of the differences. Good Question. Both PubMed and Web of Science are human-curated databases. Google Scholar is not. This is the key to most of the differences you will find in your search results.

This means: Journals are the focus of Web of Science and PubMed, and they are selected for inclusion by humans based on scholarly and quality criteria by literature review committees. See: PubMed journal selection or Web of Science journal selection Data about each article is entered into the database in a uniform structured way: author, title, date, journal name.

This means you get accurate retrieval when searching for those things. Results can be sorted reliably by latest date. Articles in PubMed are tagged with important information about their structure , such as "review article" or "clinical trial". They are tagged with structured words about their content and major topics to help you get better search results.

Articles in Web of Science are also tagged with important information about their structure, such as "review article". They are not tagged for content, so you must include all possible variations of the topic you are searching. Of the three, PubMed has the most "bells and whistles" to help you get good search results.

These databases have subject specificity in that journals are chosen for inclusion in PubMed or Web of Science based on subject matter. PubMed focuses on clinical and biomedical literature. Web of Science is interdisciplinary and includes the "best" journals of each subject area. Accurate retrieval means that search results are reproducible and reportable especially important for systematic reviews In contrast, Google Scholar is not a human-curated database but a search engine of the whole internet which narrows the results to "scholarly " ones based on machine automated criteria.

Criteria for inclusion as "scholarly" in Google Scholar results is based on publishers submitting information to Google Scholar about their web sites, and is not necessarily based on the attributes of the sources themselves. Not all publishers may have worked equally with Google. Some included journals may be poor quality or even predatory journals. Books, reports, theses, preprints, and other types of sources are all included.

PubMed remains an optimal tool in biomedical electronic research. Scopus covers a wider journal range, of help both in keyword searching and citation analysis, but it is currently limited to recent articles published after compared with Web of Science.

Google Scholar, as for the Web in general, can help in the retrieval of even the most obscure information but its use is marred by inadequate, less often updated, citation information.
