Controlled Languages (CLs) are language standards with restricted vocabulary and grammar. They are used primarily for two purposes: to improve clarity for human readers and to improve the processibility of language by computers. The first CL was created to improve language pedagogy, but the concept has been adapted to the needs of industrial technical documentation, foreign language translation, knowledge engineering, and speech interfaces. Successful commercial applications of CL technology include controlled language checkers and machine translation systems. Controlled Language technology is expected to play a significant role in knowledge representation systems and command-and-control machine interfaces in the future.
