Computational linguistics originated in the 1950s with efforts to automatically translate texts between languages. It was observed that in order to translate one language to another, the grammar of both languages must be understood, including morphology, syntax, semantics, and pragmatics. This evolution from machine translation to understanding natural languages using computers formed the basis of computational linguistics as a discipline. Computational linguistics applies linguistic theories and computational techniques to natural language processing and involves studying computer systems that understand and generate human language.

QUESTIONS AND ANSWERS

2. WHAT IS COMPUTATIONAL LINGUISTICS ALL
ABOUT?
 Computational linguistics is the application of linguistic
theories and computational techniques to natural
language processing.
 Ralph Grishman, the author of the book, Computational
Linguistics defined CL as the study of computer systems
for the purpose of understanding and generating natural
language.

3. ORIGIN OF CL
 Computational linguistics originated with efforts in the
United States in the 1950s to use computers to
automatically translate texts from foreign languages
 In order to translate one language into another, it was
observed that one had to understand the grammar of both
languages, including both morphology (the grammar of
word forms) and syntax (the grammar of sentence
structure).
 In order to understand syntax, one had to also understand
the semantics and the lexicon(or 'vocabulary'), and even to
understand something of the pragmatics of language use.
 Thus, what started as an effort to translate between
languages evolved into an entire discipline devoted to
understanding how to represent and process natural
languages using computers.
