Dimensions is a database of abstracts and citations and of research grants, which links grants to resulting publications, clinical trials and patents. Dimensions is part of Digital Science (or Digital Science & Research Solutions Ltd) - a technology company headquartered London, United Kingdom. The company focuses on strategic investments into startup companies, that support the research lifecycle.

Contents

Dimensions was launched in 2018. [1] Some of its data is accessible free-of-charge at app.dimensons.ai.

Coverage

As of July 2023, Dimensions.ai covers nearly 140 million publications with over 1.8 billion citations. [2]

Two studies published in 2021 compared Dimensions with its subscription-based commercial competitors Scopus and Web of Science. The first study concluded based on 2010-2018 data, that Dimensions indexes three times more journals that Web of Science (excluding its Emerging Sources Citation Index), and almost twice as many as Scopus. [3] The other study attempted to match citations in these three databases as well as Google Scholar and Microsoft Academic Graph, and found that Scopus and Dimensions are on par in terms of coverage, but smaller and Microsoft Academic Graph or even Google Scholar.

CiteSeerX is a public search engine and digital library for scientific and academic papers, primarily in the fields of computer and information science.

A citation index is a kind of bibliographic index, an index of citations between publications, allowing the user to easily establish which later documents cite which earlier documents. A form of citation index is first found in 12th-century Hebrew religious literature. Legal citation indexes are found in the 18th century and were made popular by citators such as Shepard's Citations (1873). In 1961, Eugene Garfield's Institute for Scientific Information (ISI) introduced the first citation index for papers published in academic journals, first the Science Citation Index (SCI), and later the Social Sciences Citation Index (SSCI) and the Arts and Humanities Citation Index (AHCI). American Chemical Society converted its printed Chemical Abstract Service into internet-accessible SciFinder in 2008. The first automated citation indexing was done by CiteSeer in 1997 and was patented. Other sources for such data include Google Scholar, Microsoft Academic, Elsevier's Scopus, and the National Institutes of Health's iCite.

Scopus is an abstract and citation database launched by the academic publisher Elsevier in 2004.

<span class="mw-page-title-main">Bibliometrics</span> Statistical analysis of written publications

Bibliometrics is the application of statistical methods to the study of bibliographic data, especially in scientific and library and information science contexts, and is closely associated with scientometrics to the point that both fields largely overlap.

Scientometrics is a subfield of informetrics that studies quantitative aspects of scholarly literature. Major research issues include the measurement of the impact of research papers and academic journals, the understanding of scientific citations, and the use of such measurements in policy and management contexts. In practice there is a significant overlap between scientometrics and other scientific fields such as information systems, information science, science of science policy, sociology of science, and metascience. Critics have argued that overreliance on scientometrics has created a system of perverse incentives, producing a publish or perish environment that leads to low-quality research.

Citation analysis is the examination of the frequency, patterns, and graphs of citations in documents. It uses the directed graph of citations — links from one document to another document — to reveal properties of the documents. A typical aim would be to identify the most important documents in a collection. A classic example is that of the citations between academic articles and books. For another example, judges of law support their judgements by referring back to judgements made in earlier cases. An additional example is provided by patents which contain prior art, citation of earlier patents relevant to the current claim. The digitization of patent data and increasing computing power have led to a community of practice that uses these citation data to measure innovation attributes, trace knowledge flows, and map innovation networks.

<span class="mw-page-title-main">Google Scholar</span> Academic search service by Google

Google Scholar is a freely accessible web search engine that indexes the full text or metadata of scholarly literature across an array of publishing formats and disciplines. Released in beta in November 2004, the Google Scholar index includes peer-reviewed online academic journals and books, conference papers, theses and dissertations, preprints, abstracts, technical reports, and other scholarly literature, including court opinions and patents.

The h-index is an author-level metric that measures both the productivity and citation impact of the publications, initially used for an individual scientist or scholar. The h-index correlates with success indicators such as winning the Nobel Prize, being accepted for research fellowships and holding positions at top universities. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications. The index has more recently been applied to the productivity and impact of a scholarly journal as well as a group of scientists, such as a department or university or country. The index was suggested in 2005 by Jorge E. Hirsch, a physicist at UC San Diego, as a tool for determining theoretical physicists' relative quality and is sometimes called the Hirsch index or Hirsch number.

The Science Citation Index Expanded is a citation index originally produced by the Institute for Scientific Information (ISI) and created by Eugene Garfield.

<span class="mw-page-title-main">Social Sciences Citation Index</span> Citation index product of Clarivate Analytics

The Social Sciences Citation Index (SSCI) is a commercial citation index product of Clarivate Analytics. It was originally developed by the Institute for Scientific Information from the Science Citation Index. The Social Sciences Citation Index is a multidisciplinary index which indexes over 3,400 journals across 58 social science disciplines – 1985 to present, and it has 122 million cited references – 1900 to present. It also includes a range of 3,500 selected items from some of the world's finest scientific and technical journals. It has a range of useful search functions such as 'cited reference searching', searching by author, subject, or title. Whilst the Social Sciences Citation Index provides extensive support in bibliographic analytics and research, a number of academic scholars have expressed criticisms relating to ideological bias and its English-dominant publishing nature.

<span class="mw-page-title-main">Web of Science</span> Online subscription index of citations

The Web of Science is a paid-access platform that provides 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.
