DTIC Subject Categorization Study, Part 1 SCG Uses and Suggested Field Changes, Part 2 Subject Categorization Methodology

摘要

This study presents a least cost approach to revising and enhancing DTIC's Subject Categorization Guide for Defense Science and Technology dated Oct 1986. The research is presented in two parts: Part I is concerned with how the present Subject Categorization Guide is being utilized and offers some recommendations for other usages. Changes are suggested on restructuring portions of the Guide where existing terminology does not fully support large segments of incoming documents. The frequency distribution of DTIC documents, based on Fields and Groups that entered the database between 1960 and 1997, is given for the classified entries, document orders and the subject fields. This data graphically portrays the changes that have occurred in the subject fields and groups. Part II is concerned with information accessibility and communicability where the SCG has been used more or less as a technological tool for information management and control. A number of changes are suggested and reasons are given encouraging DTIC to adopt these changes. Conclusions are that the subject groupings of technical documents in a manner readily understood by DTIC's user community significantly contributes to database usage, customer satisfaction,and the efficiency of the total DTIC information network. DTIC is tasked by its mission to provide and maintain an efficient categorization scheme.
