Scopus
Scopus is a scientific abstract and citation database, launched by the academic publisher Elsevier as a competitor to older Web of Science in 2004.[needs update] The ensuing competition between the two databases has been characterized as "intense" and is considered to significantly benefit their users in terms of continuous improvement in coverage, search/analysis capabilities, but not in price. Free database The Lens completes the triad of main universal academic research databases.[citation needed]
Journals in Scopus are reviewed for sufficient quality each year according to four numerical measures: h-Index, CiteScore, SJR (SCImago Journal Rank) and SNIP (source normalized impact per paper). For this reason, the journals listed in Scopus are considered to meet the requirement for peer review quality established by several research grant agencies for their grant recipients and by degree-accreditation boards in a number of countries.
Scopus also allows patent searches from a dedicated patent database, Lexis-Nexis, albeit with limited functionality. At present, Scopus indexes the following patent databases: United States Patent and Trademark Office (USPTO); European Patent Office (EPO); Japan Patent Office (JPO): World Intellectual Property Organization (WIPO); UK Intellectual Property Office.
Comparing ease of use and coverage of Scopus and the Web of Science (WoS), a 2006 study concluded that Scopus is "easy to navigate, even for the novice user.[...]The ability to search both forward and backward from a particular citation would be very helpful to the researcher. The multidisciplinary aspect allows the researcher to easily search outside of his discipline." and "One advantage of WOS over Scopus is the depth of coverage, with the full WOS database going back to 1945 and Scopus going back to 1966. However, Scopus and WOS complement each other as neither resource is all inclusive." A small number of studies found approximately an 80-90% overlap in coverage between WoS and Scopus for the period between 1990 and 2020.
In terms of the structured query language search capabilities Scopus is somewhat more advanced than Web of Science: for example, WoS can perform only NEAR/n queries, Scopus can also do PRE/n queries.[jargon]
Also, when the same article was covered in Scopus and in the Web of Science, its Scopus entry had a keyword ratio 3-5 of than its WoS counterpart, and the Scopus keywords are more focused on the specific article content, whereas WoS has more keywords related to the broad category of the article's subject. A larger number of narrow-targeted keywords allows Scopus users to find a larger number of relevant publications, while filtering out false positives. On the other hand, WoS exports (e.g. in the RIS format) the DOI numbers of cited articles, while Scopus exports the titles of cited articles. Also, Scopus allows exporting 20,000 references (e.g., as a RIS file) at once, while WoS export is limited to 5,000 references at once.
Scopus provides chemical search by CAS number and by chemical name, while WoS does not have these features. On the other hand, WoS has chemical structure search, but only a small number of publications are actually indexed for chemical structure searches. SciFinder is the preferred option for chemical searches in all cases.
Scopus also offers author profiles which cover affiliations, number of publications and their bibliographic data, references, and details on the number of citations each published document has received. It has alerting features that allow registered users to track changes to a profile and a facility to calculate authors' h-index. In 2016, a gratis website, Scopus CiteScore, was introduced. It provides citation data for all 25,000+ active titles such as journals, conference proceedings and books in Scopus and provides an alternative to the impact factor, a journal-level indicator which may correlate negatively with reliability.
