摘要：

A Selective Dissemination of Information (SDI) system is described which has been implemented on a minicomputer. The first part of the paper discusses the preparation of profiles, and the role of the information scientist in their testing and maintenance. The second part discusses the methods of implementation of SDI programs, in particular the trade-off between memory capacity and speed which must be faced. The current matching algorithm at DSIS is described in greater detail. Somewhat over 1,000 questions are matched every two weeks against about 2,500 document records, producing about 12,000 individual retrievals.
