Corpus linguistics is the systematic study of language using large collections of authentic texts, called corpora. However, there are several interchangeable terms that refer to corpus linguistics. For instance, corpus-based linguistics or corpus-driven linguistics takes a quantitative approach to language analysis, relying on a computerized database of language data. Another synonym is corpus analysis, which encompasses the process of retrieving, manipulating, and analyzing data in corpora to answer linguistic questions. Additionally, computational linguistics refers to the application of computer science to linguistics, including corpus linguistics. Finally, corpus-assisted discourse analysis focuses on the use of corpora to investigate language use in discourse or communication.
