Abstract: In this paper we propose refocusing the research from knowledge portals towards frameworks, which the end user can apply in many decision-making scenarios and which we call ||personal portals||. Rather than pouring resources into a centralised access to knowledge repository, we suggest a more distributed approach to accessing knowledge. The core facets of such approach include: choice from multiple ontologies; dynamic selection of ontological frames; customisation of user interaction and knowledge-level inference results; and decoupling the content from a variety of contexts using the principles of conceptual (re-)framing. A prototype of such approach Magpie is described to illustrate some of these tenets. Magpie is our ||zero-overhead|| suite of tools facilitating three distinct perspectives on the Semantic Web: as a methodology for supporting the interpretation of web resources through ||ontological lenses||, as a tool kit for supporting and realising Semantic Web browsing, and as a framework for building semantic web applications.
Keywords: semantic web; semantic services; document interpretation; conceptual framing; Magpie; personal portals; decision making; knowledge access; distributed knowledge; ontologies; web resources; web services; knowledge management; knowledge sharing.
