Abstract:
In order to choose the best services among various services across the world, how much a service can be trusted is increasingly important for service consumers. In addition, if services are invoked by machines, it is increasingly crucial that the trust in services can be calculated automatically. However, most existing approaches are based on the assumption that the trust value can be provided by consumers, but ‘how’ is not solved. In this paper, criteria of Quality of Service (QoS) are classified into different groups, and an automatic trust calculation is introduced. After that, an approach based on the Kalman Filter is presented to filter out malicious values and to estimate real values. Through aggregating the values provided by other consumers, the value of the trust in different QoS criteria can be obtained. Finally, experiments are carried out to access the validation and robustness of our model.
