A computerized information control system was established in Ebara Manufacturing company. This system known as ETICS(Ebara Technical Information Control System) enables the company to store quickly, or retrieve technical information necessary to Ebara. This system aims at storage, and maintaining external as well as internal technical information for re-use at an instant's notice. The retrieval system is mechanized by electronic computer with the adoption of SDI(abbreviation of Selective Dissemination of Information), and RS(abbreviation of Retrospective Search). The manual searching is a available for internal technical information. In regard to the technical information outside the company, this system uses ready-made magnetic tape that is available on the market. The explanation will be given on the synopsis of ETICS and the results of the retrieval experiments with regards to the retrieval time and the retrieval precision on SDI. As the qualitative ways for saving the retrieval time is known to some degrees, the quantitative measurement of retrieval time was carried out in this attempt. It becomes clear that the retrieval time is influenced comparatively by the number of keywords and the truncation. On an ordinary occasion, the unit time of retrieval in SDI is from 20ms to 40ms. In regard to the retrieval precision, contents of questions were devided into 3 stages, i.e., in broad concept, medium wide concept, and narrow concept, and comparisons of the results of machine searching against the result of manual seaching were described. As the content of question is widened, there is a tendency showing the drop in relevance factor and at the same time, raise in recall factor.
