The following is a list of links to Case-Based Reasoning tool vendors and consultants. You can add details of your own tool or consulting organisation to this list by using the ai-cbr information form. There are now many commercially available Case-Based Reasoning development tools. Each has different functionality and will suit different requirements. If your organisation is wondering which tool to use you may be interested in ai-cbr's consultancy and training services. A full review and feature comparison of Case-Based Reasoning software is given in the recent book Applying Case-Based Reasoning - techniques for enterprise systems. An older review of some of the most widely used Case-Based Reasoning tools is also available in A Review of Industrial Case-Based Reasoning Tools.
