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.
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 ACM Computing Research Repository uses a 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 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.
