25-542: According to the Journal Citation Reports , the journal has a 2020 impact factor of 8.934. The journal has implemented the Transparency and Openness Promotion guidelines that provide structure to research planning and reporting and aim to make research more transparent, accessible, and reproducible. In the early years of the 20th century, Baldwin purchased Cattell's interest in the journal, but

50-615: A citation index. For example, a paper's influence can be determined by linking to all the papers that have cited it. In this way, current trends, patterns, and emerging fields of research can be assessed. Eugene Garfield , the "father of citation indexing of academic literature", who launched the Science Citation Index , which in turn led to the Web of Science, wrote: Citations are the formal, explicit linkages between papers that have particular points in common. A citation index

75-458: A criticism was voiced pointing toward certain deficiencies of the journal impact factor calculation process, based on Thomson Reuters Web of Science, such as: journal citation distributions usually are highly skewed towards established journals; journal impact factor properties are field-specific and can be easily manipulated by editors, or even by changing the editorial policies; this makes the entire process essentially non-transparent. Regarding

100-429: A unifying research tool which enables the user to acquire, analyze, and disseminate database information in a timely manner". This is accomplished because of the creation of a common vocabulary, called ontology , for varied search terms and varied data. Moreover, search terms generate related information across categories. Acceptable content for Web of Science is determined by an evaluation and selection process based on

125-601: Is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science . As a journal-level metric , it is frequently used as a proxy for the relative importance of a journal within its field; journals with higher impact factor values are given the status of being more important, or carry more prestige in their respective fields, than those with lower values. Web of Science The Web of Science ( WoS ; previously known as Web of Knowledge )

175-447: Is built around these linkages. It lists publications that have been cited and identifies the sources of the citations. Anyone conducting a literature search can find from one to dozens of additional papers on a subject just by knowing one that has been cited. And every paper that is found provides a list of new citations with which to continue the search. The simplicity of citation indexing is one of its main strengths. Web of Science "is

The issue for each year

275-470: The SCImago Journal Rank . Furthermore, as of September 2014, the total file count of the Web of Science was over 90 million records, which included over 800 million cited references, covering 5.3 thousand social science publications in 55 disciplines. Titles of foreign-language publications are translated into English and so cannot be found by searches in the original language. In 2018,

300-654: The Web of Science and is accessed from the Web of Science Core Collection . It provides information about academic journals in the natural and social sciences , including impact factors . JCR was originally published as a part of the Science Citation Index . Currently, the JCR , as a distinct service, is based on citations compiled from the Science Citation Index Expanded and

325-470: The Web of Science hosts a number of regional citation indices: The seven citation indices listed above contain references which have been cited by other articles. One may use them to undertake cited reference search, that is, locating articles that cite an earlier, or current publication. One may search citation databases by topic, by author, by source title, and by location. Two chemistry databases, Index Chemicus and Current Chemical Reactions allow for

350-742: The Web of Science started embedding partial information about the open access status of works, using Unpaywall data. While marketed as a global point of reference, Scopus and WoS have been characterised as «structurally biased against research produced in non-Western countries, non-English language research, and research from the arts, humanities, and social sciences». After the 2022 Russian invasion of Ukraine , on March 11, 2022, Clarivate – which owns Web of Science – announced that it would cease all commercial activity in Russia and immediately close an office there. The Web of Science Core Collection consists of six online indexing databases: Since 2008,

375-549: The above disciplines. Among other WoS databases are BIOSIS and The Zoological Record , an electronic index of zoological literature that also serves as the unofficial register of scientific names in zoology . Clarivate owns and markets numerous other products that provide data and analytics, workflow tools, and professional services to researchers, universities, research institutions, and other organizations, such as: As with other scientific approaches, scientometrics and bibliometrics have their own limitations. In 2010,

400-434: The core collection and 171 million records on the platform. A citation index is built on the fact that citations in science serve as linkages between similar research items, and lead to matching or related scientific literature, such as journal articles , conference proceedings , abstracts, etc. In addition, literature that shows the greatest impact in a particular field, or more than one discipline, can be located through

425-669: The coverage of Web of Science, in November 2009 Thomson Reuters introduced Century of Social Sciences .

550-434: The more objective journal metrics, there is a growing view that for greater accuracy it must be supplemented with article-level metrics and peer-review. Studies of methodological quality and reliability have found that "reliability of published research works in several fields may be decreasing with increasing journal rank". Thomson Reuters replied to criticism in general terms by stating that "no one metric can fully capture

575-604: The number and quality of articles published in journals indexed in the JCR. In recent years, it has often been released in mid-June.
