5. 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

6. 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.

8. 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
