Checking the reliability of information sources in recommendation based trust decision making

Abstract

Trust is one of the measures commonly used to evaluate the effectiveness of agents in cooperative societies. For building trust of a specific target, agents utilize their direct experiences and recommendations from agents who had mutual experience with the target. Some agents may provide false data due to misjudgment. Some others may have biased or extreme behavior toward evaluating others. Having the possibility of false data necessitate the existence of reliability checking mechanisms in building trust. This research focuses on showing the effect of reliability checking mechanisms on recommendation-based trust decision making.
