An object-oriented model of case-based reasoning system using situations tree

The article is dedicated to development of an object-oriented model of an intelligence system based on case-based reasoning (CBR). An upgrade of the decision tree has been introduced to represent the situations hierarchy and related decisions in the knowledge base. The construction of the situations tree has been described. The problem of representing the situations tree in terms of classes and objects has been solved and the method of storage of the situations tree in the database has been defined. As a result, on the basis of the object-oriented paradigm the proposed approach allows creating domain-independent CBR systems that are shells for filling with case-oriented knowledge to solve specific problems.
