Approaching Factors and Dimensions with Explanation-Based Argumentation

Current research in legal argumentation theory tries to bridge the gap be-tween representations of the arguments brought by parties, and representations of factors and dimensions, as used in case-based reasoning frameworks. The present paper targets the same objective, but taking an alternative approach. Instead of reasoning in terms of attack or support relationships between claims, we consider the relation of the collected messages with alternative interpretations of the case, thus referring to explanation-based argumentation (EBA). This shift of perspective allows us to start an alternative investigation into some of the questions raised in the literature. A prototype application is presented along with the paper.
