Case Based Reasoning

• CBR is based on a collection of cases.
• You figure out what to do in each case in the collection, you may do the same thing in several cases.
• When a new case comes in, you compare it to the collection.
• You give the advice of a nearby case.
• An example might be a trouble shooting desk. 90% of the queries fall in 10 categories.
• Figure out what category it is in (including the 11th other category), give the appropriate advice, or in the other case, phone a help person.
• This saves 90% of your help person time (after development).
• What would a case look like?
• How do you tell which cases are near to the new case?
