One of the most interesting topics in social network research is opinion formation. In this paper we have introduced a new dependent multi-dimensional opinion formation method. This method models agents with several dependent opinions so that modifying the agent's opinion about one issue can affect its opinion about another issue. Agents share their opinion with agents which have trusted them. A directed...
Usually, agents within multiagent systems represent different stakeholders that have their own distinct and sometimes conflicting interests and objectives. They would behave in such a way so as to achieve their own objectives, even at the cost of others. Therefore, there are risks in interacting with other agents. A number of computational trust models have been proposed to manage such risk. However,...
Trust management is important for agent cooperation and security in multi-agent system. Based on rough sets theory, a new trust evaluation method is proposed. The method divides attributes into necessary or unnecessary, calculates attribute weight, and then evaluates trust values by using a decision-making method. Finally, an example shows that it is efficient to evaluate trust by using the method.
