A trustworthy service computing framework through a semantic messaging model

In this paper, we present a framework supporting reliable and trustworthy service-oriented workspace sharing environments. To this end, we propose a communication model to facilitate a complex level of interactions among workspace participants. To implement a communication model, we adopted a frame-based approach, in which each frame has slots to be filled. Slots in a frame are analyzed and filled using the semantic information provided from service participants. In addition, we provide a trust model for predicting behaviors of service providers. Our trust model ensures reliability by indicating the extent to which a service is reliable. To estimate risks and the degree of service satisfaction, we employ historical user ratings. In addition, we evaluated a case from the design and manufacturing domain. We conclude that our proposed approach will contribute to realizing trustworthy workspace sharing in a service oriented environment.
