This chapter provides an introduction to the paradigm of case-based reasoning, an approach to the design of knowledge-based systems which implements the idea that classification and problem-solving depend crucially on remembering similar past episodes. At the heart of any case-based system is a standard sequence of steps that has been described in detail, summarized as ‘retrieve, reuse, revise, and retain’. As a field, CBR has rapidly reached maturity, as evidenced by the number of commercial applications in use, as well as the existence of numerous development tools and methodologies. The current technological level in the field allows rapid development of help-desk-like applications, which are characterized by the simplicity of their representational structures and similarity function. However, limitations of current technology become apparent with more complex tasks.

Keywords:   case-based reasoning, knowledge-based systems, problem-solving, representational structures, similarity function, complex tasks
