Case-Based and Multimodal Reasoning: the contribution of Piero Torasso

The paper reports the contribution of Piero Torasso to the field of Case-Based Reasoning (CBR), with particular attention to the role of CBR in multi-modal diagnostic problem solving. Starting from the idea that CBR could be adopted to focus model-based reasoning during diagnostic problem solving, Piero’s work concentrated on all the different steps of the CBR cycle, namely case retrieval, solution adaptation and case base maintenance. This resulted in the construction of a multi-modal system called ADAPtER that was used during all the phases of his research activity, both as a basis for the theoretical work and for the necessary experimental analysis
