## Abstract

We describe a "'PESTION-ANSWER" information system implemented on computer BESII-6 in the time-shared system. The "~STION ANSWER" system is capable of deducing facts that have not been explicitly given to it by using a large data base and interpreting some of data as rules of inference. The system employs a special procedure which allows not to use contradictory information even if it is contained in the data base
