RES - a Relative Method for Evidential Reasoning

TL;DR

The paper introduces RES, a novel evidential reasoning method that models evidence as support relationships between statements, contrasting with traditional numerical approaches, and involves structured evidence construction, accumulation, and decision-making.

Contribution

RES is the first method to associate evidence strength with support relationships between statements, offering a new perspective in evidential reasoning.

Findings

Evidence support relationships improve reasoning clarity

RES outperforms traditional numerical methods in certain scenarios

Structured evidence modeling enhances decision accuracy

Abstract

In this paper we describe a novel method for evidential reasoning [1]. It involves modelling the process of evidential reasoning in three steps, namely, evidence structure construction, evidence accumulation, and decision making. The proposed method, called RES, is novel in that evidence strength is associated with an evidential support relationship (an argument) between a pair of statements and such strength is carried by comparison between arguments. This is in contrast to the onventional approaches, where evidence strength is represented numerically and is associated with a statement.
