The Structure of Disagreement in Emotion Annotation

Read the original on arXiv Computation and Language →

The paper investigates the patterns of disagreement in emotion annotation by analyzing multilabel annotations from 1,677 sentence-level units of Hemingway’s *The Old Man and the Sea* and comparing them with individual-level annotations from BRIGHTER and GoEmotions. It identifies three recurring disagreement structures: systematic overlap of emotion categories, differences in label breadth and boundary treatment, and sparse participation or abstention that mimic disagreement. The study shows that hard aggregation obscures these patterns, while annotator vote-share representations preserve only marginal frequencies, and it proposes a vocabulary for describing disagreement structure.

Beyond Consensus: Perspectivist Modeling and Evaluation of Annotator Disagreement in NLP

The paper surveys how annotator disagreement in NLP is increasingly treated as a meaningful signal rather than noise. It offers a domain‑agnostic taxonomy of disagreement sources, a unified framework for modeling approaches, and a review of evaluation metrics for predictive performance and annotator behavior. The authors highlight a shift toward explicit disagreement modeling, structured annotator relationships, and outline future challenges such as integrating multiple variation sources and developing interpretability frameworks.

A Resource for Enthymeme Detection in Controversial Political Discourse

Enthymemes, arguments with unstated premises or conclusions, are pervasive in persuasive discourse, yet their annotation remains notoriously subjective. We present a resource of 1,482 tweets from politically controversial discourse, annotated by five annotators for the presence of enthymemes and their argument structure, designed to study label variation.
