Summary

  • Knowledge model components
    • Knowledge model:
      • specialized tool for specification of knowledge-intensive tasks
      • abstracts from communication aspects
      • real-world oriented
      • reuse is central theme
    • Task knowledge
      • goal-oriented
      • functional decomposition
    • Domain knowledge
      • relevant domain knowledge and information
      • static
    • Inference knowledge
      • basic reasoning steps that can be made in the domain knowledge and are applied by tasks
  • Template knowledge models
    • Knowledge models partially reused in new applications
    • Type of task = main guide for reuse
    • Catalog of task templates
    • reusable combination of model elements
      • (provisional) inference structure
      • typical control structure
      • typical domain schema from task point-of-view
    • specific for a task type
    • supports top-down knowledge modeling
