Rules Wiki

This part of the wiki is dedicated to general rule-related topics, including:

  • expert systems (ES)
  • rule-based systems (RBS)
  • business rules (BR)
  • etc.

It serves both as a research and didactic resource.

This wiki is created by the members of the HeKatE project, but also by other researchers and students. It is not related to HeKatE itself, or its development.

The wiki is english-only, and all of the pages are in the rules namespace.
