A Tale of Two Communities: An Analysis of Three Decades of Case-Based Reasoning Research

We analyse three decades of case-based reasoning (CBR) research to better understand the health of CBR and its relationship to adjacent research fields. We identify two largely separate CBR communities, one based on the research published at mainstream CBR venues (ICCBR, ECCBR etc.), the other encompassing CBR work with no direct connection to these venues. We analyse their scale, impact, and focus, and the potential to bring them closer together in the future.
