研究期間：10108~10207;This work presents an innovative agent architecture, which enhances the current web service to a very high abstraction level where group agents interacts with each other to provide intelligent, dynamic, and personalized services for group users. In Semantic Web, the web ontology language (OWL) be used to encode semantic information content (called meta-data) over the Web. The OWL annotates not only web resources, but also web services by using web ontology language for service (OWL-S) to form semantic web services. Most importantly, the software entity called agent proactively interprets these semantic information (meta-data and semantic web service) to provide intelligent services. Further, agents can form agent groups according to their user profiles to achieve group goal. The layers of this agent architecture, in top-down order, are: 1) Group agent layer, 2) Group Interaction Protocol Layer, 3) Group Mentality Layer, 4) Semantic Behavior Layer, 5) Workflow Layer, and 6) Semantic Web Service Layer. Note that beneath the lowest "Semantic web service layer" lies the current web service layer. An example is included to illustrate the concept. The implementation will be based on Jadex (Jade extended), OWL, and Java. And, a group travel agent system will be fully implemented for demo at the end of this work.
