A classification system for military functions, technologies, and sciences

Systems for classifying or categorizing areas of science and technology are required, not only for use in information retrieval operations, but also for methods used for R&D project selection and evaluation. This paper describes the background and development of one such system which was devised for information retrieval purposes. Either the system itself, or the methods by which it was devised, may be of use to others facing problems similar to those of the organization for which it was devised.
