Case-based Reasoning for Experience-based Collaborative Risk Management

In a collaborative risk management scenario, project stakeholders often need natural forms of recording and reusing past risk management experiences so that they could better assess whether there are threats to the goals of new projects. The contribution of this paper is to propose an enhanced case-based reasoning (CBR) approach to support project participants to exploit such experiences which are here expressed as collaborative risk management discussion cases. The paper shows how these debates are structured through the exploitation of a dialogue game protocol for risk management. Then, it discusses how users can utilize queries based on facts and arguments so that past risk discussion cases could be retrieved from a case base. Attention is also given to case-based explanation templates, which are relevant for the understanding of key moves of argumentation in debate trees recorded in such enhanced cases retrieved. To demonstrate the practical utility of this approach, a case study involving the collaborative experience-based risk management of a software project is discussed.
