bert-large-finnish-cased-v1 for toxicity detection

This is the bert-base-finnish-cased-v1 model, fine-tuned using the Finnish jigsaw_toxicity_pred_fi dataset. The model is trained to predict probabilities for 6 different toxicity labels introduced in the dataset card.

Overview

Language model: bert-base-finnish-v1

Language: Finnish

Downstream-task: Multi-label toxicity detection (multi-label text classification)

Training data: jigsaw_toxicity_pred_fi

Eval data: jigsaw_toxicity_pred_fi

    abstract = "Due to the popularity of social media platforms and the sheer amount of user-generated content online, the automatic detection of toxic language has become crucial in the creation of a friendly and safe digital space. Previous work has been mostly focusing on English leaving many lower-resource languages behind. In this paper, we present novel resources for toxicity detection in Finnish by introducing two new datasets, a machine translated toxicity dataset for Finnish based on the widely used English Jigsaw dataset and a smaller test set of Suomi24 discussion forum comments originally written in Finnish and manually annotated following the definitions of the labels that were used to annotate the Jigsaw dataset. We show that machine translating the training data to Finnish provides better toxicity detection results than using the original English training data and zero-shot cross-lingual transfer with XLM-R, even with our newly annotated dataset from Suomi24.",

Usage

the model can be used through a huggingface pipeline:

model = transformers.AutoModelForSequenceClassification.from_pretrained("TurkuNLP/bert-large-finnish-cased-toxicity")
tokenizer = transformers.AutoTokenizer.from_pretrained("TurkuNLP/bert-large-finnish-cased-v1")
pipe = transformers.pipeline(task="text-classification", model=model, tokenizer=tokenizer, function_to_apply="sigmoid", top_k=None)
