Case-based reasoning is standardly formalised as having four-steps – retrieve, reuse, revise, and retain. In this formalisation, there is little scope for debate. However, in domains such as law, medicine, and product selection, participants (lawyers, doctors, or consumers) may argue for or against a given legal determination, clinical treatment plan, or product choice based on what is retrieved from the case base, how the cases are reused, and what revisions are made to a case. The participants must not only justify their argument, but also defend it against counter-arguments; as well, subsidiary arguments must be justified and defended. Moreover, the information in the case base may be incomplete; different individuals to the dispute may hold alternative views, values, or consumer-oriented goals; and the reasoning itself may only be plausible rather than certain. Given this, we resort to defeasible argumentation on information derived from the case base, where claims only presumptively follow from premises and reasoning about the overall ‘network’ of arguments can be related to alternative contexts or audiences. At the end of the reasoning process, some decision must be made, which may vary depending on audiences.

Recent research on formalising or supporting decision-making in social systems (law, medicine, consumer discussion websites) shows the crucial role of argumentation in structuring, clarifying, and reasoning with respect to complex, possibly inconsistent information. Bringing researchers together to discuss results across domains will lead to greater understanding of commonalities or problems and forward state-of-the-art research on the intersection of and interaction between case-based reasoning and argumentation.
