WoS provides unique search methods and cited searching. Users can navigate forward and backward through the literature, and search all disciplines and time periods. Users can navigate to print and electronic collections using institutional linkresolvers.
Web of Science (WoS) is searchable with complete bibliographic data, cited reference data and navigation and links to full text.
Scopus gives four types of quality measure for each title; those are h-Index, CiteScore, SJR (SCImago Journal Rank) and SNIP (Source Normalized Impact per Paper). Also, it is is Elsevier’s abstract and citation database . There is no impact evaluation here. Web of Science It is an online subscription-based scientific citation indexing and maintained by Clarivate Analytics. Web of Science employs various search and analysis capabilities such as citation indexing. selection of the papers is basis of impact evaluation. It has six online databases.
Web of Science is an online subscription based scientific citation indexing service originally produced by the Institute for Scientific Information (ISI).
Web of Science is an online mammoth subscription-based scientific citation indexing service originally produced by the Institute for Scientific Information (ISI), now maintained by Clarivate Analytics. The database has current and retrospective coverage from 1900 to the present. It includes 34,200 journals along with numerous books, proceedings, patents, and data sets.
WoS is now available with its core collection bundled with specialist databases. Specialist databases are with a subject focus like Medline, BIOSIS Citation Index, CAB Direct, and Zoological Record. Databases with a document type focus like Derwent Innovations Index (patents) and Data Citation Index (datasets and data studies) and databases highlighting content from regions around the world are also included. If you want to access Web of Science, you require subscription and IP authentication. Visit: https://clarivate.com/products/web-of-science/.
Scopus is an interdisciplinary bibliographic online database launched in 2004 containing abstracts and citation database as a competitor to Web of Science. Scopus is owned by Elsevier, an international publication group. Scopus covers diverse subjects coming under physical and environmental sciences, life sciences, health sciences, social sciences, engineering, business, and management. Access to Scopus is through subscription only. It covers about 36,000 journal titles from more than 11,000 international publishers in scientific, medical, technical, and social science fields, of which nearly 34,000 are peer-reviewed journals. Just like Web of Science and Google Scholar, Scopus also provides citation information. For more details, visit http://www.scopus.com/.
Note that the h-index from WoS and Scupus could vary because of the differences in data sources. For example, if one particular database indexes and draws data from a larger number of journals, then it may have more citations.
In other words, h-index calculated based on Scopus, Web of Science, Google Scholar, and ResearchGate would differ. In my experience, h-index obtained from Google Scholar is higher than all the others.
If we want to consider WOS as a better database I would say that if the journals are indexed in ISI listed probably the value of study is lower than those indexed in Scopus. As a result, Both of Scopus and WOS (Just ISI, not ISI listed) are equal in reputation.
If you are interested in an in-depth comparison of search capabilities of 28 systems (incl. SCOPUS, Web of Science, Google Scholar, PubMed...) here is our new paper: Article Which Academic Search Systems are Suitable for Systematic Re...
A platform consisting of several literature search databases designed to support scientific and scholarly research. The Web of Science provides a common search language, navigation environment, and data structure allowing researchers to search broadly across disparate resources and use the citation connections inherent to the index to navigate to relevant research results and measure impact. > 34,200 journals + books, proceedings, patents, and data sets. A platform providing access to multidisciplinary and regional citation indexes; specialist subject indexes; a patent family index; and an index to scientific data sets. There are databases with a subject focus like Medline, BIOSIS Citation Index, and Zoological Record; databases with a document type focus like Derwent Innovations Index (patents) and Data Citation Index (datasets and data studies); and databases highlighting content from regions around the world.
Scopus
The world’s largest abstract and citation database of peer-reviewed literature, including scientific journals, books, and conference proceedings, covering research topics across all scientific and technical disciplines, ranging from medicine and social sciences to arts and humanities. Further, with smart tools to track, analyze and visualize research, Scopus empowers you to advance your science beyond the text. Since 2004, Scopus has delivered a comprehensive overview of the world's scientific research output across all disciplines. And it’s only getting better. Scopus features smart tools to track, analyze and visualize research - all so you can identify emerging trends, increase the visibility of your research, build a collaborative network, bolster funding applications and articulate the value of research to your organization.
WoS and Scopus are two different publications database. Every database has its own system and corresponding journals. Both are generally recognized as reliable indexing databases.
WoS or Web of Science is a journal search and indexing database. Likewise Scopus is also a Journal indexing database with search for citations, references etc and is relatively more common and appears to be more accepted.
Scopus burst on the research scene in 2004 claiming it had the biggest database with the most information. Web of Science rejoined with the claim of having the most depth and the most quality. Web of Science covers the peer-reviewed journal literature, over 8,000 titles, with a concentration on the sciences but with some (23%) social science and arts and humanities titles. Their selection of which titles to cover is influenced by the number of citations within those journals. The much debated "journal impact factor" is discussed on their site for those interested. There is also a focus on English language material, and a U.S. bias. Web of Science has started covering a few open access journals, though Scopus claims to cover 500 of these as well (Thomson 2006c).
WOS and scopus are the two separate websites. I think WOS have more data base than scopus. WOS is administered by Clarivate analytics and Scopus is administered by Elsevier. However, both of the sites are a reliable source in the world, I think .
WOS and Scopus are two valuable and well accepted data base. Web of Science (WOS) is administered by Clarivate Analytics and Scopus is administered by Elsevier.
Scopus and Web of Science both are essential indicators for indexing service provider. Scopus by Elseveir while Web of Science is own by Clarivate Analytics.
In my opinion there is edge to
Clarivate Analytics with 04 indexing types, while Elsevier only one type of Indexing.
I think both of them have their own advantages. WOS IS clarivate analysis and Scopus by elvisteir. Scopus is a large interdisciplinary database from Elsevier, with particular strengths in science and technology. The bibliometric & citation features use the whole of the Scopus database.
Web of Science (previously known as Web of Knowledge) is a collection of databases maintained by Thomson Reuters,
Both publishing articles in journals indexed in the Web of Science database of scientific texts and / or in the Scopus database can significantly increase the visibility of published research results in the world of science, the visibility of published scientific works on the Internet and can increase the scale of citation. At the University where I operate, both indexation databases of articles / scientific papers are recognized as key, although at many University Faculties, the Scopus indexation database appears more often in many recommendations, recommendations and suggestions regarding the selection of journals for publishing scientific articles. However, this does not exclude the high level of relevance of publishing also in journals indexed in the Web of Science database.
For my point of view, Web of Science is more selective than Scopus. Traditionally, it is based upon English based publications and covers mostly the publication from the Western region especially from the USA and British. Scopus has been known to be supportive towards non-spoken English regions such as the Asia and the Middle East.
There are many publications which describe the comparison between both indexes. What you say was right at one time, but since scopus has come, wos changed its coverage to match with scopus one. Today both indexes are very close, except that scopus still covers more journals, which explains that the h index of individuals are usually slightly higher with scopus than with wos - as more journals means more overall citations, which are the basis of calculation for the h index.
Scopus claims to be the largest abstract and citation database of research literature and quality web sources. ... Web of Science (WoS) is searchable with complete bibliographic data, cited reference data and navigation and links to full text.
Beyond h and IF, SCOPUS and WoS offer an analytical description of the publications of an author: topics, journals, co-authors, countries, funding sources, etc... which is much indicative when searching for collaborators or assessing profiles
WOS journals are more strict in the peer-to-peer review process coz they seek to publish high standard research papers. Personally, I have found that all WOS journals in my research field are indexed by SCOPUS but NOT vice versa.
Hi Dr G. Rathinasabapathy . Web of Science collects information on the natural, technical, and social sciences, Scopus also has a wide variety of publications in the humanities field, although neither of them is considered to be specialized. See the link: https://www.internauka.org/en/blog/scopus-vs-web-of-science
Detailed review on both can be found at: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwjS14OUt5HzAhWMwzgGHdyJA78QFnoECBgQAQ&url=https%3A%2F%2Fwww.mdpi.com%2F2304-6775%2F9%2F1%2F12%2Fpdf&usg=AOvVaw0OcTsZ-m3CMk-nmlw4Q8Bu&cshid=1632274199992944
Both Scopus and Web of Science are indexing bodies. These two indexers index reputed journals. Web of Science indexed journals are considered more reputed journals than Scopus indexed journals.
Web of Science journals categories journals into SCIE, ESCI, AHCI, and SSCI journals. Only the SSCI and SCIE journals have impact factors.
There are many journals that are being indexed by both of these indexers.
