The Association for Computational Linguistics (ACL) is the international scientific and professional society for people working on problems involving natural language and computation. An annual meeting is held each summer in locations where significant computational linguistics research is carried out. It was founded in 1962, originally named the Association for Machine Translation and Computational Linguistics (AMTCL). It became the ACL in 1968.
The ACL has a European (EACL) and a North American (NAACL) chapter.
The ACL journal, Computational Linguistics, is the primary forum for research on computational linguistics and natural language processing. Since 1988, the journal has been published for the ACL by MIT Press.
