A reference architecture for knowledge management-based web systems

Knowledge Management-based Web Systems (KM-bWS) are a novel class of Web Information Systems whose main goal is to adapt contents and presentations with respect to user needs and backgrounds through the execution of Knowledge Management processes. KM-bWS involve complex issues such as knowledge representation, classification and clustering, reasoning, and, more recently, ontologies and semantic Web. In this paper we present a methodology for the designing and developing of KM-MYS, starting from the application domain analysis. We also provide a reference multi-layer architecture for KM-bWS. In our opinion, a KM-bWS can be considered as an "intelligent knowledge hub" because it makes distributed Web resources available by means of Knowledge Management techniques such as classification and clustering. Finally, we present a reference model for developing a KM-bMS authoring toot able to support our methodology.
