Embodiment Construction

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail by taking a travel recommendation system as an example and referring to the accompanying drawings.

[0024] The flow chart of the method of the present invention is as follows figure 1 shown, including the following steps:

[0025] Step 1, Agent knowledge representation.

[0026] In step 1.1, the background knowledge and preference knowledge expressed by the intermediary agent and all user agents are represented by PASP.

[0027] Taking the scenario of tourist attraction recommendation as an example, the problem of multi-agent belief coordination is illustrated. The travel recommendation system (Intermediary Agent) recently recommended three tourist attractions and listed their descriptions:

[0028] (1) The three attractions are Japan, Hong Kong China, and Xi'an China.

[0029] (2) If the weather in the scen...

Abstract

The invention discloses a multi-agent belief coordination method based on PASP, which can solve the conflict problem in the multi-agent non-intersecting belief situation. The method includes: agent's knowledge representation; weighted quantification; constructing a consistent coordination procedure. First, the agent system knowledge is represented by PASP; then, according to the different belief sets of each agent, the satisfaction degree of the answer set of the PASP relative to the agent's belief is calculated based on the weighted quantitative method, so as to weaken some beliefs, and introduce the default decision theory Infer the consensus solution of the agent's belief coordination; finally, build a consensus coordination program according to the consensus solution, which is the background knowledge base that the agents agree on. It belongs to the field of multi-Agent system and logic programming.

Description

technical field [0001] The invention relates to the field of multi-Agent system and logic program design, in particular to a PASP-based coordination method for multi-Agent disjoint belief scenarios. Background technique [0002] With the development of computer technology, network technology and communication technology, multi-agent system has become a very active research direction in the field of artificial intelligence. Many domestic and foreign scholars have conducted theoretical and practical research in this field, and successfully applied Agent technology in the fields of fault diagnosis, microgrid energy management, and transportation resource scheduling. [0003] In a multi-agent system, different agents may have different beliefs, which will inevitably lead to conflict of actions due to the conflict of beliefs. Therefore, an acceptable agreement needs to be formed between agents, and the process of forming an agreement is called coordination between agents. Coord...
