  10. Rules-Based Decision Support Tool Information (Facts) Inference Engine User KnowledgeBase User’s Documents Decision Knowledge Acquisition System Human Experts AI Data Mining

  11. Inferential Logic What hypothesis is supported by the given facts? Knowledge Development (e.g. interview experts) FACTS (e.g. sensor status) Backward Chaining Inference Engine: Software that examines database so as to find links between FACTS and HYPOTHESES Rule Database: Collection of unsorted /unlinked Rules (e.g. IF_____ THEN______) Forward Chaining What facts are required to support a given hypothesis? What are the rules being used to support a final conclusion (e.g. required facts or hypothesis?) HYPOTHESIS (e.g. incursion event)
