Adding Dimensions and Facts to ADF Representation of Legal Cases

Latifa Al-Abdulkarim, Katie Atkinson, Trevor Bench-Capon

Abstract

Previous work has shown that theories representing a body of case law can be represented as Abstract Dialectical Frameworks (ADF) but that it is desirable to represent degrees of presence of factors, rather than as simply considering factors as present or absent, as is currently standard. This requires consideration not only of factors, but also of the facts on which their attribution to cases is based. In this paper we revive the use of dimensions, from which factors developed, to mediate between facts and factors so as to achieve a structured and transparent representation of degrees of presence of factors. We will illustrate our exploration using the much discussed wild animal cases.
