technology in which computers actually try to learn from the database and operator what the right answer is to a question. The system gets positive or negative response to output from the operator and stores that data so that it will make a better decision the next time. While still in its infancy, this technology shows promise for use in accounting, fraud detection, economic forecasting, and risk appraisals. The idea behind this software is to convert the order-taking computer into a "thinking" problem solver.
