  • 1. Tomas Sabol - Peter Macej [email_address] sk Peter. Macej @ tuke . sk Technical University of Kosice Slovakia
  • 2. Areas of activities/expertise
    • Knowledge management
    • Knowledge modeling and acquisition
    • Ontologies
    • Data mining
    • Machine learning
    • The most relevant Projects:
    • Esprit 29065 “KnowWeb”
    • IST-1999-20364 “Webocracy”
  • 3. Esprit 29065 “KnowWeb”
    • Development of Ontology-based KM tool
    • Efficient information/knowledge management and intelligent retrieval in the organization
    • Application domain modeled by ontology
    • A set of tools:
      • Ontology builder
      • Document annotator
      • Retrieval engine
  • 4. Ontology in KnowWeb
  • 5. Annotating documents
    • Documents are associated with attributes and concepts from ontology
    • Manually, semi-automatically
    • Templates (rules) for semi-automatic annotation
    • Any document type (HTML, MS Office, image, movie, …)
    • Whole documents or their fragments
    • In graphical environment/in the background from external application
  • 6. “ Webocracy” Project Architecture INTERFACE Knowledge Model Logic DB Ontology Server INTERFACE Webocrat system Webocrat Server Client Client
  • 7. Ontology Server
    • Standalone, reusable in various systems
    • Manages ontology
    • Query processing
    • Using OKBC (Open Knowledge Base Connectivity) standard – provides easy cooperation with many knowledge systems
    • Written in Java
    • Portable to many platforms
  • 8. Our (potential) contribution to the AOS Project:
    • Universal ontology server providing all functionality needed by AOS
    • Ontology Editor (Protégé 2000) customized to AOS needs
    • Methodology and practice for building ontologies
    • Retrieval engine
