Concordancer

A concordancer is a computer program that automatically constructs a concordance. The output of a concordancer may serve as input to a translation memory system for computer-assisted translation, or as an early step in machine translation.

Concordancers are also used in corpus linguistics to retrieve alphabetically or otherwise sorted lists of linguistic data from the corpus in question, which the corpus linguist then analyzes.

A number of concordancers have been published, notably Oxford Concordance Program (OCP), a concordancer first released in 1981 by Oxford University Computing Services, which claims to be used in over 200 organisations worldwide.
