Theoretical CL

The subject of the theoretical computational linguistics is cognitive basis of natural language

It deals with issues of cognitive processes formalisation, specification of discrete units in cognition and language, formulation the principles of natural language functioning as a system

Theoretical CL has an intersection with general theoretical linguistics and cognitive science

Applied CL

Applied computational linguistics focuses on the direct practical outcome of the studies

It uses mathematical methods and computational basis for natural language modeling and processing, creating databases and corpuses, text processing, machine translation and other related operations

Applied CL often stands for CL in general.

The Association

The Association for Computational Linguistics (ACL) was founded in 1962 as the Association for Machine Translation and Computational Linguistics. In 1968 it became the ACL.

The ACL has two chapters: European and North American

The ACL has Computational Linguistics journal and Studies in Natural Language Processing book series

Each year ACL organizes international conferences
