Abstract: In this paper, we propose a conceptual architecture for a personal
semantic Web information retrieval system. It incorporates semantic Web, Web
service, P2P and multi-agent technologies to enable not only precise location
of Web resources but also the automatic or semi-automatic integration of Web
resources delivered through Web contents and Web services. In this
architecture, the semantic issues concerning the whole lifecycle of information
retrieval were considered consistently and the integration of Web contents and
Web services is enabled seamlessly. The architecture consists of three main
components: consumer, provider and mediator. All providers and consumers are
constructed as semantic "MyPortal" which provides a gateway to all the
information relevant to a user. Each provider describes its capabilities in
what we call a WSCD (Web site capability description), and each consumer will
submit relevant queries based on user requirements when a Web search is
necessary. The mediator is composed of agents assigned to the consumer and
providers using an Agent-Community-based P2P information retrieval (ACP2P)
method to fullfill the information sharing among semantic MyPortals. Some
preliminary experimental results are presented to show the efficiency of the
ACP2P method and the usefulness of two query/response histories for looking up
new information sources and for reducing communication loads.
