On a common approach to joining productive rules obtained from different knowledge sources

This paper discusses the problem of joining production rules obtained from knowledge sources of different typology (experts, problem-oriented texts, electronic carriers in the form of databases) with a view to building complete and consistent knowledge bases in integrated expert systems. It describes the properties of distributed knowledge acquisition within the target-oriented methodology for building integrated expert systems and automatic technology created on its basis that includes new-generation instruments - an AT-TECHNOLOGY software complex. The problems of using the theory of multisets to join productive rules obtained from different knowledge sources are considered.
