Abstract

This paper presents a new method for implementing in hardware expert systems based on belief revision concepts. The expert system’s knowledge base is first automatically translated to an equivalent network representation where nodes are facts and links stand for relationships. Then, changes are propagated throughout the network. The conclusions are extracted after no more changes occur in the state of the nodes. The automatic generation of the hardware network structure is described. Finally, the results obtained in this FPGA-based implementation are compared to those yielded by a Java-based implementation, the system’s efficiency being thus demonstrated.
