However, such judgments are inherently subjective, often leading to a lack of agreement and, consequently, variability when multiple experts assess the same material. This variability, referred to as inter-rater variability, is typically addressed by aggregating scores or applying majority voting to produce a consensus decision. While effective for obtaining a final decision, this approach leaves the underlying causes of inter-rater variability largely unexplored.This thesis aims to explain inter-rater variability rather than treating consensus decisions as an absolute reference. We argue that such variability may arise from systematic differences between experts, particularly in terms of professional background, training, and the perceptual dimensions emphasized during assessment. By reducing individual judgments to a single consensus score, traditional approaches implicitly discard valuable information about expert reasoning and decision-making strategies. Understanding and explaining this variability is therefore essential.To address this objective, we propose a computational approach to model and interpret inter-rater variability.
