A Framework of Constructing and Evolving Trusted Services with Formulation

Trusted services might play a key role in the future Internet and modern service industry. In this paper, we present a framework for constructing and evolving trusted services based on the service science. Due to the uncertain and vague aspects of the semantic category of the service trustiness, we provide an approach of representing and evaluating service trustiness with the Trusted Ontology which can be understood and processed by the computers. Aimed to make the semantic computing formalization and the Trusted Ontology executable, the trusted service computing model has been implemented to transform the process of the service trustiness evaluation into the problem-solving model based on the sub-ontology evolution mechanism. Finally, the instances of trusted service application have been presented with its comparable experimental results in order to validate the performance effect of the service computing and trustiness evaluation.
