Page "Computational linguistics" Paragraph 4

When machine translation ( also known as mechanical translation ) failed to yield accurate translations right away, automated processing of human languages was recognized as far more complex than had originally been assumed.

Computational linguistics was born as the name of the new field of study devoted to developing algorithms and software for intelligently processing language data.

When artificial intelligence came into existence in the 1960s, the field of computational linguistics became that sub-division of artificial intelligence dealing with human-level comprehension and production of natural languages.
