Web of Science The Web of Science ( WoS ; previously known as Web of Knowledge )

132-458: 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

165-522: A new headquarters north of campus. Ground was broken in 1971 for an expansion to the building designed by architects Brubaker/Brandt to accommodate the review of 400,000 new research reports printed each year. The 5-story 142,000 square foot building opened in May 1973. In 2007, the ACS designated its Chemical Abstracts Service subdivision an ACS National Historic Chemical Landmark in recognition of its significance as

198-475: A selected journal. Also included is its language of text and language of summaries. The range is from 1907 to the present, including both serial and non-serial scientific and technical publications. The database is updated quarterly. Beyond CASSI lists abbreviated journal titles from early chemical literature and other historical reference sources. Chemical Abstracts ( CA ) began as a volunteer effort and developed from there. The use of volunteer abstractors

231-429: 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

264-469: Is a database of chemical and bibliographic information. Originally it was available only as a client application (for both Windows and MacOS operating systems), a web version was released in 2008. By that time it had a graphical interface, and was able to do graphical searches for chemical structures and reactions (the first database to allow such functions), as well as keyword searches for literature in chemistry and related disciplines. SciFinder Scholar

297-484: Is a paid-access platform that provides (typically via the internet) access to multiple databases that provide reference and citation data from academic journals , conference proceedings , and other documents in various academic disciplines . Until 1997, it was originally produced by the Institute for Scientific Information . It is currently owned by Clarivate . Web of Science currently contains 79 million records in

330-447: 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

363-433: Is made on the basis of impact evaluations and comprise academic journals , spanning multiple academic disciplines . The coverage includes: the sciences , social sciences , the arts , and humanities, and goes across disciplines. However, Web of Science does not index all journals.

Since 2009, this formerly print and CD-ROM compilation is available as a free online resource to look up and confirm publication information. The online CASSI Search Tool provides titles and abbreviations, CODEN , ISSN , publisher , and date of first issue (history) for

429-529: The National Institutes of Health . The chemical information is produced by CAS, and is prepared by the CAS Registry System, which identifies each compound with a specific CAS registry number , index name, and graphic representation of its chemical structure. The assignment of chemical names is done according to the chemical nomenclature rules for CA index names, which is slightly different from

462-461: 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,

495-470: 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

528-738: 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,

561-549: 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,

825-467: The journal evaluation metric CiteScore, has identified 216 journals from 70 publishers to be in the top 10 percent of the most-cited journals in their subject category based on the CiteScore while they did not have an impact factor. It appears that the impact factor does not provide comprehensive and unbiased coverage of high-quality journals. Similar results can be observed by comparing the impact factor with

858-434: 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

891-416: The present day. This technology points to a deficiency with the keyword -only method of searching. Second, subtle trends and patterns relevant to the literature or research of interest, become apparent. Broad trends indicate significant topics of the day, as well as the history relevant to both the work at hand, and particular areas of study. Third, trends can be graphically represented. Expanding

924-559: The west bank of the Olentangy River , just north of The Ohio State campus. This campus became well known in the Columbus area and famous as the site of many Columbus Symphony Orchestra pop concerts. In 2009, the campus consisted of three buildings. In 1907, William A. Noyes had enlarged the Review of American Chemical Research , an abstracting publication begun by Arthur Noyes in 1895 that

957-477: Was a key factor in its long-term success. Dale B. Baker became the CAS Director upon Crane's retirement in 1958. According to CAS, his visionary view of CAS' potential "led to expansion, modernization, and the forging of international alliances with other information organizations." CAS was an early leader in the use of computer technology to organize and disseminate information. The CAS Chemical Registry System

990-551: Was a very similar a product developed for academic institutions, but discontinued in 2023. In 2017 the ACS released SciFinder-n as a web-only product with the same data content and improved user interface and search functions. SciFinder is considered as the best source of chemical information worldwide, with substantially larger number of relevant information sources than Web of Science or Scopus with Reaxys . However, due to its unique and unusual search functions, substantial training

1023-401: Was introduced in 1965. CAS developed a unique registry number to identify chemical substances. Agencies such as the U.S. Environmental Protection Agency and local fire departments around the world now rely on these numbers for the definite identification of substances. According to the ACS, this is the largest chemical substance database in the world. In 1965, CAS left their offices at OSU for
