Description

Case-based closing" is a procedure for solving problems by analogy. The central element in a CBR system is a so-called case basis (a case database) in which problems that have already been solved are stored as cases. Such a case consists at least of a problem description and an associated problem solution.

The aim is to solve a given problem by using the solution of a similar problem that has already been solved. It's an imitation of human behavior: Faced with a new problem, man often remembers a comparable situation he has experienced in the past and tries to master the current task in a similar way.

Case Based Reasoning has proven itself especially in the area of incremental innovations, but also in applications for help desk systems, where it is used, for example, for the diagnosis and therapy of customer problems. More recently, it has been increasingly used in (product) consulting systems, for example in e-commerce, and for the classification of texts.

It is considered advantageous that CBR can also be applied to poorly structured and incompletely described problems.

As always, if one argues with analogies, it must be ensured that the solution proposals generated by the system are adequate for the problem at hand, i.e. whether, for example, the preconditions on which the historical solution was based are still fulfilled and so on (obsolescence of knowledge).
