Learning Clips, while I don't mind the syntax I'm finding it difficult to derive rules from facts. Is there a tip on how to structure rules given a knowledge base? A non trivial example would be nice, thanks.
Basically this is the entire field of "knowledge engineering;" it's really as broad a question as "given a domain, how do I architect application software for that domain?" Whole books have been written on this topic. Here are three that treat this topic well IMO: Peter Norvig's "Artificial Intelligence, A Modern Approach", Giarratano and Riley's "Expert Systems: Principles and Programming", and my "Jess In Action".
