The Oxford Concordance Program Version 2
SUSAN HOCKEY, J. Martin · Literary and Linguistic Computing · 1987
In 1978 Oxford University Computing Service embarked on a project to write a machine independent text analysis program to produce word lists, indexes and concordances in a variety of languages and alphabets. The resulting program, called the Oxford Concordance Program, or OCP, was first released in 1981 and has now been licensed to some 240 institutions in 23 countries. During 1985-6 OCP was completely rewritten. In the new version there has been some rationalisation of the OCP commands, but the principal aim was to increase the efficiency of the program. This article gives an overview of OCP, concentrating on the changes which have been made for version 2 and demonstrating the increased efficiency.
