{{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 organiseorganize subjects by area.

==Structure==

It is hierarchically structured in four levels. Thus, forFor example, one branch of the hierarchy contains:

The ACM Computing Classification System, version 2012, has a revolutionary change in some areas, for example, in "Software" that now is called "Software and its engineering" which has three main subjects:

* Software organization and properties. This subject addresses properties of the software itself.

* Software notations and tools. This subject covers programming languages and other tools for writing programs.

* Software creation and management. This subject covers human activities including software management.

It is hierarchically structured in four levels. Thus, 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.
