Multilingual Hate Speech Classifier for Social Media with Disagreement-Aware Training

A multilingual XLM-R-based (100 languages) hate speech classification model fine-tuned on English, Italian and Slovenian with inter-annotator disagreement-aware training.

The details of the model and the disagreement-aware training are described in our paper:

Data available here: English; Italian; Slovenian

Model output The model classifies each input into one of four distinct classes:

0 - appropriate
1 - inappropriate
2 - offensive
3 - violent

Training data*

51k English Youtube comments
60k Italian Youtube comments
50k Slovenian Twitter comments

Evaluation data*

10k English Youtube comments
10k Italian Youtube comments
10k Slovenian Twitter comments

* each comment is manually labeled by two different annotators

Fine-tuning hyperparameters

  num_train_epochs=3,
  train_batch_size=8,
  learning_rate=6e-6

Evaluation Results Model agreement (accuracy) vs. Inter-annotator agreement (0 - no agreement; 100 - perfect agreement):

	Model-annotator Agreement	Inter-annotator Agreement
English	79.97	82.91
Italian	82.00	81.79
Slovenian	78.84	79.43

Class-specific model F1-scores:

	Appropriate	Inappropriate	Offensive	Violent
English	86.10	39.16	68.24	27.82
Italian	89.77	58.45	60.42	44.97
Slovenian	84.30	45.22	69.69	24.79

Usage

from transformers import AutoModelForSequenceClassification, TextClassificationPipeline, AutoTokenizer, AutoConfig

MODEL = "IMSyPP/hate_speech_multilingual"
tokenizer = AutoTokenizer.from_pretrained(MODEL)
config = AutoConfig.from_pretrained(MODEL)
model = AutoModelForSequenceClassification.from_pretrained(MODEL)

pipe = TextClassificationPipeline(model=model, tokenizer=tokenizer, return_all_scores=True,
task='sentiment_analysis', device=0, function_to_apply="none")
pipe([
"Thank you for using our model",
"Grazie per aver utilizzato il nostro modello"
"Hvala za uporabo našega modela"
