Scientific citation

Scientific citation is the process of systematically acknowledging sources from which information, data, ideas, or direct quotations are drawn in scholarly work. Sources in science are typically previously published peer-reviewed journal articles, books, theses or dissertations, conference papers, and rarely private or public communications. Citations connect a researcher's work with existing literature, ensuring transparency, academic integrity, and safe outcomes such as in medical science. Effective citation practices require clear, standardized mechanisms for referencing materials, particularly crucial as electronic publishing and online data repositories expand rapidly. Scientists generate new knowledge by practicing the scientific method on the thoughts, ideas, and work that scientists did before them. By applying scholarly principles, scientists may report their findings which become part of the chain of knowledge. Citations profoundly shape the structure of scientific knowledge by explicitly linking new research with existing academic literature. They define line of thought, give context to research within larger academic debates, and contribute to shared scholarly memory. Accurate citation practices that knowledge is verifiable, essential for scientific advancement. Like any complex system, there are problems, write large, with scientific citation. One issue is that rapid increase in digital data creates challenges in reliably verifying datasets due to a lack of standardized referencing practices, especially for online sets of data. Additionally, citation bias arises when researchers disproportionately reference studies based on reputation or ease of access rather than merit, potentially marginalizing equally valid but less visible research. Also, citations can sometimes unintentionally distort or misrepresent original data or contexts, either through oversight, misunderstanding, or selective interpretation, thereby complicating accurate knowledge transfer and verification.

Patent references In patent law, the citation of previous works, or prior art, helps establish the uniqueness of the invention being described. The focus in this practice is to claim originality for commercial purposes, and so the author is motivated to avoid citing works that cast doubt on their originality. This does not appear to be "scientific" citation. Inventors and lawyers have a legal obligation to cite all relevant art; not doing so risks invalidating the patent. The patent examiner is obliged to list all further prior art found in searches.

Citation analysis

Citation frequency

Modern scientists are sometimes judged by the number of times their work is cited by others—this is actually a key indicator of the relative importance of a work in science. Accordingly, individual scientists are motivated to have their own work cited early and often and as widely as possible, but all other scientists are motivated to eliminate unnecessary citations so as not to devalue this means of judgment. A formal citation index tracks which referred and reviewed papers have referred which other such papers. Baruch Lev and other advocates of accounting reform consider the number of times a patent is cited to be a significant metric of its quality, and thus of innovation. Reviews often replace citations to primary studies. Citation-frequency is one indicator used in scientometrics.

Replication crisis Some studies explore citations and citation-frequencies. Researchers found that papers in leading journals with findings that can not be replicated tend to be cited more than reproducible science. Results that are published unreproducibly – or not in a replicable sufficiently transparent way – are more likely to be wrong, may slow progress and, according to an author, "a simple way to check how often studies have been repeated, and whether or not the original findings are confirmed" is needed. The authors also put forward possible explanations for this state of affairs.

Progress and citation consolidation

Two meta-analyses reported that in a growing scientific field, citations disproportionately cite already well-cited papers, possibly slowing and inhibiting progress to some degree. They find that "structures fostering disruptive scholarship and focusing attention on novel ideas" could be important. Other metascientists introduced the 'CD index' intended to characterize "how papers and patents change networks of citations in science and technology" and reported that it has declined, which they interpreted as "slowing rates of disruption". They proposed linking this to changes to three "use of previous knowledge"-indicators which they interpreted as "contemporary discovery and invention" being informed by "a narrower scope of existing knowledge". The overall number of papers has risen while the total of "highly disruptive" papers has not. The 1998 discovery of the accelerating expansion of the universe has a CD index of 0. Their results also suggest scientists and inventors "may be struggling to keep up with the pace of knowledge expansion".

IT systems

Research discovery

Recommendation systems sometimes also use citations to find similar studies to the one the user is currently reading or that the user may be interested in and may find useful. Better availability of integrable open citation information could be useful in addressing the "overwhelming amount of scientific literature".

Q&A agents Knowledge agents may use citations to find studies that are relevant to the user's query.
