  1. Knowledge Management: The On-To-Knowledge Project Hans Akkermans Free University Amsterdam VUA

  2. What is On-To-Knowledge? • European project in EU Information Society Technologies Programme: EU-IST-10132 • Aim: innovative tools for knowledge management • Duration: 2.5 years, January 2000 - June 2002 • Total effort & cost: 26 personyears, 2.5+ M EUR • EC funding: 1.34 M EUR On-To-Knowledge

  3. Free Univ. Amsterdam (VUA, coordinator), NL British Telecom, UK Swiss Life, CH Aidministrator, NL CognIT, NO EnerSearch, SE AIFB Uni-Karlsruhe, D OTK Partners On-To-Knowledge

  4. What is Knowledge Management? (1/2) Peter Drucker: Post-capitalist Society (1993) • “The change in the meaning of knowledge that began 250 years ago has transformed society and economy. Formal knowledge is seen as both the key personal resource and the key economic resource. Knowledge is the only meaningful resource today. The traditional `factors of production' - land (i.e. natural resources), labour and capital - have not disappeared. But they have become secondary. They can be obtained, and obtained easily, provided there is knowledge. And knowledge in this new meaning is knowledge as a utility, knowledge as the means to obtain social and economic results. These developments, whether desirable or not, are responses to an irreversible change: knowledge is now being applied to knowledge.” On-To-Knowledge

  5. Maintain, Control quality Acquire Develop Foster use Plan Distribute Identify Dispose What is Knowledge Management? (2/2) The knowledge value chain Aim of Knowledge Management: • Increase the leverage of corporate knowledge, as a key production factor in the organization On-To-Knowledge

  6. Exploiting World-Wide Information Resources • IT, and especially Internet/WWW, have boosted potential for knowledge acquisition and sharing • BUT: information resources are heterogeneous, distributed, semi-structured, & enormous in size • HENCE: need for KM tools for selective semantic (meaning-oriented) access => On-To-Knowledge • Move from keyword search to query answering • Move upwards in the data-info-knowledge chain • Vision:toward the next-generation “semantic” (Tim Berners-Lee, W3C) or knowledge web On-To-Knowledge

  7. Tools: Intranet/WWW information extraction Semantic representation & analysis User query access OTK Results (1/2) On-To-Knowledge

  8. Methodology (inputs: e.g. our KE&M book, MIT Press, Cambridge, MA, 2000) Industrial case studies: evaluation and feedback OIL: XML/RDF-based ontology language plus inference layer on top of the web OTK Results (2/2) Note: see Chapter 9 for EnerSearch case study on agent communication On-To-Knowledge

  9. What is an Ontology? • In philosophy: theory of what exists in the world • In IT: formal description of shared concepts in a domain • Aid to human communication and shared understanding, by specifying meaning • Machine-processable (e.g., agents use ontologies in communication) • Ontology = key technology in semantic information processing • Application: knowledge management, e-business On-To-Knowledge

  10. OTK Tool Environment and its Use On-To-Knowledge

  11. Project Roles of OTK Partners On-To-Knowledge

  12. EnerSearch Case Study: Virtual Enterprise (1/3) • How to do knowledge transfer via website? • Issue: hyperlinks or keyword search do not tell you much, and are a waste of time • Much better: you want to ask questions and just get the answer Note: EnerSearch website hyperlink structure does not really help! On-To-Knowledge

  13. EnerSearch Case Study: What You Can Do (2/3) Note: EnerSearch website ontology gives organization of important topics (Excerpt) • Annotate documents or webpages with meaning (through ontology) • Note: taxonomy or type hierarchy is simple(st) form of ontology • Next: semantic clustering of pages gives content-based organization • Automatically done by one of the OTK tools: Aidministrator’s WebMaster On-To-Knowledge

  14. EnerSearch Case Study: Preliminary Results (3/3) • Key idea: website hyperlinks + ontology = meaningful structure Author relations Agent subtype structure Interactive generation of subtype intersections (here, e-commerce) On-To-Knowledge

  15. EnerSearch Case Study: Involvement of Shareholders • Request to participate in evaluation of OTK tools • User query interface tool: ask questions rather than browse or search • Test/evaluation feedback to On-To-Knowledge • => Improve EnerSearch website as a knowledge transfer medium 2 1 Ontology helps separate two different meanings of “communication” On-To-Knowledge
