A plan recognizing algorithm based on fuzzy cognitive plan map

Abstract

With plan recognition applications continuously expanding, the speed of traditional plan recognition is too slow, which hampers plan recognition applying to some areas. So, it is important to construct simple and efficient plan recognizing algorithm. Based on the study of plan knowledge graph, the concept of fuzzy cognitive plan map is proposed. Then, the recognizing algorithm based on fuzzy cognitive plan map is proposed. In this algorithm, it uses the operation of matrix to recognize agent’s plan, which can overcome the inefficiency of searching graph in plan knowledge graph. Experimental results show that the plan recognizing algorithm has excellent performance in plan recognition and the same recognition result is true for plan knowledge graph and it can reduce the recognition time greatly. The algorithm of plan recognition does well in intelligent game, smart home, network security and other fields, which has an important significance for extending the application area of plan recognition.
