Book Description
The report describes a large-scale computerized system for Selective Dissemination of Information (SDI) developed over the past five years at the U.S. Army Electronics Command to serve its technical personnel. The system, which uses as its document base the current accessions of the Defense Documentation Center, was developed in three phases: an 18-month semiautomated test with 50 subscribers, a fully automated system with about 500 subscribers, and a proposed standard system for Army use. System descriptions include profiling techniques, keyword matching strategies, processing procedures, flow charts, and samples of inputs and outputs. System effectiveness is evaluated in terms of document ordering, relevance of citations, and the impact the system has had on the R and D program as revealed by responses to questionnaires. (Author).

Book Description
This report presents an analysis of over eighteen small, intermediate, and large-scale systems for the selective dissemination of information (SDI). Systems are compared and analyzed with respect to design criteria and the following ten system parameters: information input, methods of indexing and abstracting, user interest profile construction, user group profile/document match strategy, profile maintenance and updating, products disseminated, operating statistics accumulated, ADP equipment utilized, and results reported. From the results of the analysis, criteria are drawn for the design of an SDI system that is generally applicable to a broad range of Army technical libraries. The design criteria are used as a basis for designing an SDI system which has the following desired characteristics: broad applicability, acceptance of information in many different formats, ability to yield high relevancy for specific information requirements, and high recall for general information requirements. This system requires a minimum automatic data processing configuration and operating personnel. Operating costs are minimized by utilizing standard graphic reproduction techniques for reproducing multiple copies of SDI notices. The user profile/document match strategy incorporates both Boolean and weighted selection criteria.
