ABSTRACT
CBR is an important technology in the field of artificial intelligence. As early as the end of 1970s, some scholars have studied CBR, and the early CBR thought comes from the Rog Schank (Sha Zhongyong, 2014). In 1983, Janet Kolodner adopted the idea of Rog Schank, and developed
1 INTRODUCTION
Case-Based Reasoning (CBR) is a reasoning method adjusting the solution of previous problem to solve the current problem (Reisbeck C K, 1989). The basic process of CBR mainly includes four aspects: case retrieval, case reuse, case modification and case study. Among them, the main content of case retrieval is to retrieve the same or similar historical case set from the existing case base, and solve the current problems with the knowledge experience of historical cases. CBR is mainly based on the “similar problem with similar solution”, and it is one of the key technologies of case based reasoning to retrieve the target case which is similar to the source case.
