  case based reasoning
  CBR
  
     <artificial intelligence> (CBR) A technique for problem
     solving which looks for previous examples which are similar to
     the current problem.  This is useful where heuristic
     knowledge is not available.
  
     There are many situations where experts are not happy to be
     questioned about their knowledge by people who want to write
     the knowledge in rules, for use in expert systems.  In most
     of these situations, the natural way for an expert to describe
     his or her knowledge is through examples, stories or cases
     (which are all basically the same thing).  Such an expert will
     teach trainees about the expertise by apprenticeship, i.e. by
     giving examples and by asking the trainees to remember them,
     copy them and adapt them in solving new problems if they
     describe situations that are similar to the new problems.  CBR
     aims to exploit such knowledge.
  
     Some key research areas are efficient indexing, how to define
     "similarity" between cases and how to use temporal
     information.
