Table 1 Principal steps of the CBR cycle [10]

From: Towards case-based medical learning in radiological decision making using content-based image retrieval

Step Description
Retrieve Suitable reference cases are identified in a known set of cases based on their similarity to the original case.
Reuse Knowledge and information of the retrieved cases is used toward the solution of the original case. The solution of the retrieved case may have to be adapted to the original case prior to using it. The result of the reuse process is a suggested solution.
Revise The solution is tested, e.g., applied to the real world or evaluated by a teacher. If needed, the solution is adjusted. The result of the revision process is a confirmed solution.
Retain The new experience is incorporated into the system for future retrieval by storing the newly learned case in the case database or modifying an existing case.
