The question is do you *segregate* memory into declarative, episodic, and procedural memory. I just don't see why procedural knowledge should be mixed with declarative memory in the same container. If you put procedural knowledge in a separate memory space then you can use a more standard / conventional KR for declarative knowledge.[ I have not thought about how to apply procedural knowledge, that probably involves a lot of heuristics, and we can discuss that at a later time. ]YKY
Well, what do you actually mean when you say you would seperate it? How? It seems likely that we will have links between them all to provide easy access. If we have a frame for "book" or "reading a book" then it would seem very useful to have a reference link off there to a procedural description of reading a book, and maybe some past experiences. Likewise in the other direction, anytimg I consider the procedure or "reading a book" I will need to reference back to book to check facts and information about the object.
