A technique for 50 per cent computer time saving in the SDI service OMIKK/TIGIT

Abstract

One of the highest cost components of the Selective Dissemination of Information (SDI) is, apart from the database subscription fee, the computer time. In the SDI service TIGIT of the National Technical Information Centre and Library (OMIKK) the computer cost component has been reduced to about half of its original costs. The technique is based on the maximum compliance with the logic of the search program operation to be kept in mind during profile construction. It allowed to achieve machine time gain without investment, utilizing only intellectual effort. The author outlines the basic concepts of his method. In addition, for those using the BINAR search program, a description of the program features and the details of the time saving technique based on them is given in the Appendix.
