{{Short description|Classification system for computer science topics}}
The '''ACM Computing Classification System''' ('''CCS''') is a subject classification system for [[computing]] devised by the [[Association for Computing Machinery]] (ACM). The system is comparable to the [[Mathematics Subject Classification]] (MSC) in scope, aims, and structure, being used by the various ACM journals to organize subjects by area.

=={{anchor|CRCS 1964|CCS 1982|CCS 1983|CCS 1987|CCS 1991|CCS 1998|CCS 2012}}History==
The system has gone through seven revisions, the first version being published in 1964, and revised versions appearing in 1982, 1983, 1987, 1991, 1998, and the now current version in 2012.

==Structure==
It is hierarchically structured in four levels. For example, one branch of the hierarchy contains:
: Computing methodologies
:: [[Artificial intelligence]]
::: [[Knowledge representation and reasoning]]
:::: [[Ontology engineering]]

* The [https://arxiv.org/corr/home ACM Computing Research Repository] uses a [https://arxiv.org/corr/subjectclasses classification scheme] that is much coarser than the ACM subject classification, and does not cover all areas of CS, but is intended to better cover active areas of research. In addition, papers in this repository are classified according to the ACM subject classification.
* The [https://dl.acm.org/doi/pdf/10.1145/3664191 ACM/IEEE/AAAI Computer Science Curriculum Guidance 2023] describes a body of knowledge for computer science divided into 17 knowledge areas, similar to the above classifications.
