A Co-citation Relation is a co-item relation between publications [math]\displaystyle{ C }[/math] that all cited some other publication [math]\displaystyle{ p }[/math].
- AKA: Bibliographic Coupling Relationship, CCR.
- Context(s):
- It can be used in a Co-Citation Network.
- It can be used by a Co-Citation Index (which counts the times two or more publications are cited together).
- Example(s):
- [math]\displaystyle{ \operatorname{CCR}(C= }[/math] (Newman, 2003; Kleinberg, 1999), [math]\displaystyle{ p= }[/math] Brin & Page, 1998[math]\displaystyle{ ) }[/math] ⇒ TRUE.

- Bibliographic coupling occurs when two works reference a common third work in their bibliographies. The coupling strength is higher the more citations the two bodies have in common, and this coupling is used to extrapolate how similar the subject matter of the two works is. Bibliographic coupling is not subjectively valuable in all fields of research since it helps the researcher to find related research done in the past. A closely-related notion is the co-citation index, which refers to the number of times two works are cited together in subsequent literature.[1]
The term "bibliographic coupling" was first introduced by M. M. Kessler of MIT in a paper published in 1963,[2] and has been embraced in the work of the information scientist Eugene Garfield.[3] Others have questioned the usefulness of the concept, pointing out that the two works may reference completely unrelated subject matter in the third.
Some examples of online sites that make use of bibliographic coupling include The Collection of Computer Science Bibliographies and CiteSeer.IST

- QUOTE: … A co-citation is a shared reference of two articles to a third source. The list of co-cited references of social network research within ASR and AJS for a given year offers a rough measure of what the field collectively believes is within the canon: those sources worthy of attention and acknowledgement. …

- QUOTE: A co-citation is taken to exist if two references or authors appear in the same bibliography. A co-citation is interpreted as one data point indicating similarity in content between two works or in research interests between two authors, and the number of cocitations of two works or authors is therefore treated as a measure of their “proximity." Using a survey design, Mullins et al. (1977) and McCain (1986) have shown that the co-citational structure of a research field is a fair representation of how it is perceived by its members.

- QUOTE: … A co-citation network is constructed by drawing a line between two documents if they are cited together by a number of other works. The strength of co-citation depends on the number of sources that cite both documents, and can be represented by the number or size of lines linking the two documents (Tankard, Chang, and Tsang 1984, p. 91).

- QUOTE: A new form of document coupling called co-citation is defined as the frequency with which two documents are cited together. The co-citation frequency of two scientific papers can be determined by comparing lists of citing documents in the Science Citation Index and counting identical entries. Networks of co-cited papers can be generated for specific scientific specialties, and an example is drawn from the literature of particle physics.
