Conclusion

• Rule Based Systems consist mainly of
• an Inference Engine, which is the same for different rule bases
• a Knowledge Base (rules and working memory)
• and a UI
• The inference engine runs through a recognise and act cycle
• Rule Based Systems are fomrally as powerful as structured programming, less organised, but easier to use and understand
• It's easy to get explanatory powers from a Rule Based System by showing the rules that were applied
• For next week read sections 5.1 and 5.2, and Chapter 4 to help with the Clips command prompt.
