We start by presenting an overview of the case-based reasoning process, comparing and contrasting CBR to other AI methods to clarify motivations for the case-based approach. We then highlight key issues for CBR systems, principles for addressing them, and their role in high-impact applications and research systems. This discussion will be based on case studies of important CBR systems that reason and learn in multiple task domains. For each case study we talk about fundamental CBR issues the system addresses, consider how effective the system is in accomplishing its stated goal, and finally assess the contributions of the system to the state of the art in CBR.
Following this overview, we look at the major issues in designing and maintaining real-world CBR applications. We will define a methodology for building successful CBR systems in the real world, addressing tasks ranging from data collection and knowledge engineering to project scoping and user interface design. The tutorial closes by highlighting lessons learned from CBR research and applications, current challenges for case- based reasoning methods, how the challenges are being addressed, and opportunities for the next generation of CBR systems and their future impact.
The tutorial will clarify key principles of CBR, will supply
applications developers with the information they need to begin
selecting and applying CBR tools, and will provide experienced
professionals with an in-depth view of key issues, methods, and emerging
opportunities for applying case-based reasoning technology.
The tutorial is aimed at both researchers and application builders who
are interested in how to integrate CBR into the systems they are
building. Prior experience with CBR will certainly enhance the value of
the tutorial but is definitely not required.
