Abstract
A multi-agent system could facilitate purchase of products on the Internet by executing required buying activities. To make the multi-agent system intelligent, we propose an Information Evaluation Mechanism which adopts colleague consumers’ opinion. It uses Information Exchange Partners’ Trust Points to calculate Comparison Points of alternatives for adopting the opinion as the user’s own. We have implemented Information Evaluation Mechanism and Information Exchange Protocol in GrocShop and carried out information exchange experiments. The results thereof show that GrocShop changes its preference and purchases different goods after adopting colleague consumers’ opinion. It shows that proposed Information Evaluation Mechanism and Information Exchange Protocol are effective and useful for adopting colleague consumer’s opinion.
