Updating the Case Base

• As a system is used, it produces more cases with answers.
• Can these just be chucked in to the casebase?
• The problem is, the answers may be wrong.
• Keep the new cases and answers, but have an expert evaluate them, or let the real world answer them.
• (In the case of the bank loan, see if the loan is paid off.)
• If the expert says many of the answers are wrong, you may want to fix the system.
• If he says they are right, then you can add them.
• Note that there may be a change in the real world. (Bank loans may change.) The original cases are invalid.
• Also note that different experts may give different answers.
