Abstract

Annotators' disagreement in linguistic data has been recently the focus of multiple initiatives aimed at raising awareness on issues related to 'majority voting' when aggregating diverging annotations.Disagreement can indeed reflect different aspects of linguistic annotation, from annotators' subjectivity to sloppiness or lack of enough context to interpret a text.In this work we first propose a taxonomy of possible reasons leading to annotators' disagreement in subjective tasks.Then, we manually label part of a Twitter dataset for offensive language detection in English following this taxonomy, identifying how the different categories are distributed.Finally we run a set of experiments aimed at assessing the impact of the different types of disagreement on classification performance.In particular, we investigate how accurately tweets belonging to different categories of disagreement can be classified as offensive or not, and how injecting data with different types of disagreement in the training set affects performance.We also perform offensive language detection as a multi-task framework, using disagreement classification as an auxiliary task.Warning: This paper contains examples that may be offensive or upsetting.

  • In real scenarios, annotators may disagree for a variety of reasons, not all of which relate to a subpopulation identity.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
