Information retrieval (IR) is concerned with techniques that can provide effective access to large databases of objects that contain primarily text. It is generally assumed that there is a wide variety of users and a large number of potential queries. Although these characteristics are different than those of a typical case-based reasoning (CBR) application, there are opportunities for integration of the two approaches. To demonstrate that this is possible, we first describe IR techniques in more detail. After a brief overview of CBR, we then outline an approach to integration that takes advantage of the strengths of both approaches. We also give a simple example of how an integrated CBR/IR system could be used to address a real information need.
