Toxic Spans Detection
The Toxic Spans Detection task concerns the evaluation of systems that detect the spans that make a text toxic, when detecting such spans is possible. Moderation is crucial to promoting healthy online discussions. Although several toxicity (a.k.a. abusive language) detection datasets (Wulczyn et al., 2017; Borkan et al., 2019) and models (Schmidt and Wiegand, 2017; Pavlopoulos et al., 2017b; Zampieri et al., 2019) have been released, most of them classify whole comments or documents, and do not identify the spans that make a text toxic. But highlighting such toxic spans can assist human moderators (e.g., news portals moderators) who often deal with lengthy comments, and who prefer attribution instead of just a system-generated unexplained toxicity score per post. The evaluation of systems that could accurately locate toxic spans within a text is thus a crucial step towards successful semi-automated moderation.
