Computational linguistics is an interdisciplinary field concerned with the statistical or rule-based modeling of human language. It combines insights from linguistics, computer science, mathematics, logic, philosophy, cognitive psychology, cognitive science, anthropology, neuroscience, information engineering, and many other fields. The field is divided into two main areas: natural language processing (NLP), which focuses on the interaction between computers and human language, and computational linguistics proper, which focuses on the modeling of human language. The usefulness of computational techniques in linguistics is threefold: they can help answer classical questions (such as "Do the rules of grammar have exceptions?"), they can lead to the discovery of new linguistic phenomena, and they can help test linguistic hypotheses.

Computational linguistics has a wide range of real-world applications. In the area of natural language processing, computational linguistics is used in machine translation, speech recognition, text-to-speech, parsing, information retrieval, and other tasks that require human-computer interaction. In the area of computational linguistics proper, it is used in language modeling, corpus linguistics, and the development of linguistic theories. The field has also contributed to the development of computational models of language acquisition and processing in the brain.

The history of computational linguistics can be traced back to the early days of computer science. The first significant work in the field was done by Warren Weaver in 1949, who proposed a statistical approach to machine translation. Since then, the field has evolved significantly, with contributions from many researchers in various disciplines. Today, computational linguistics is a well-established field with its own conferences, journals, and academic programs.
