+## Dataset Motivation
+The rise in hateful and offensive language directed at other users is one of the adverse side effects of the increased use of social networking platforms. This could make it difficult for human moderators to review tagged comments filtered by classification systems.
+
+To help address this issue, we present the ViHOS (**Vi**etnamese **H**ate and **O**ffensive **S**pans) dataset, the first human-annotated corpus containing 26k spans on 11k online comments.
+
+Our goal is to create a dataset that contains comprehensive hate and offensive thoughts, meanings, or opinions within the comments rather than just a lexicon of hate and offensive terms.
+
+We also provide definitions of hateful and offensive spans in Vietnamese comments as well as detailed annotation guidelines. Futhermore, our solutions to deal with *nine different online foul linguistic phenomena* are also provided in the [*paper*]() (e.g. Teencodes; Metaphors, metonymies; Hyponyms; Puns...).
+
+We hope that this dataset will be useful for researchers and practitioners in the field of hate speech detection in general and hate spans detection in particular.
+
+## Dataset Summary
+ViHOS contains 26,476 human-annotated spans on 11,056 comments (5,360 comments have hate and offensive spans, and 5,696 comments do not)
+
+It is splitted into train, dev, and test set with following information:
+1. Train set: 8,844 comments
+2. Dev set: 1,106 comments
+3. Test set: 1,106 comments

We also provide definitions of hateful and offensive spans in Vietnamese comments as well as detailed annotation guidelines. Besides, we conduct experiments with various state-of-the-art models. Specifically, XLM-R{\_}Large achieved the best F1-scores in Single span detection and All spans detection, while PhoBERT{\_}Large obtained the highest in Multiple spans detection. Finally, our error analysis demonstrates the difficulties in detecting specific types of spans in our data for future research. Our dataset is released on GitHub.",
