Retain

Incorporate what is useful to learn from the problem solving experience into the existing knowledge. Subprocesses are:

• Extract - if the problem was solved using an old case, the system can build a new case, or generalize an old case to include the new case as well. If the user was asked, a new case should be constructed. Explanations may be included in the case.
• Index - decide what types of indexes to use for future retrieval.
• Integrate - modify the indexing of existing cases after the experience, strengthen the weight of features that were relevant, and decrease the weight of features that lead to retrieval of irrelevant cases.
