A semantic negotiation model for service property value between service agents

1This paper formulates the problem of agent negotiation in service discovery phase. We have elaborated the description model of semantic web service and agent service knowledge model. On the basis of two models, a formal approach to describing the negotiation process of service property values is proposed,and a service discovery case is designed using the agent negotiation method. The experimental results show that the designed knowledge model and the semantic negotiation protocol in service discovery can improve the understanding capability of service agents significantly. With the increase in the quantity of the deployed services and the negotiated properties, the time of returning the discovered results is prolonged slightly, but the accuracy of service discovery is advanced greatly.
