Abstract: This study integrates the case-based reasoning mechanism and international standards to develop a prototype CBRISO mechanism for resolving disputes. The CBRISO system does not fix attributes and their respective weights in advance as the traditional case-based reasoning methodologies. In order to ensure that the proposed system is user friendly and customizable, the international human-system interaction standards are applied. For the purpose of demonstration, construction disputes are used as the research theme to build the corresponding CBRISO mechanism in this study. Empirical findings suggest that the dynamic and recursive system retrieves highly suitable reference cases and predict the outcome of the target case successfully. The most important contribution of this study is consideration of end user’s needs during the progression of dispute resolution that no relevant system tried before.
