clapAI/modernBERT-base-multilingual-sentiment

Introduction

modernBERT-base-multilingual-sentiment is a multilingual sentiment classification model, part of the Multilingual-Sentiment collection.

The model is fine-tuned from answerdotai/ModernBERT-base using the multilingual sentiment dataset clapAI/MultiLingualSentiment.

Model supports multilingual sentiment classification across 16+ languages, including English, Vietnamese, Chinese, French, Spanish, Portuguese, German, Italian, Russian, Japanese, Korean, Arabic, and more.

Evaluation & Performance

After fine-tuning, the best model is loaded and evaluated on the test dataset from clapAI/MultiLingualSentiment

Model	Pretrained Model	Parameters	F1-score
modernBERT-base-multilingual-sentiment	ModernBERT-base	150M	80.16
modernBERT-large-multilingual-sentiment	ModernBERT-large	396M	81.4
roberta-base-multilingual-sentiment	XLM-roberta-base	278M	81.8
roberta-large-multilingual-sentiment	XLM-roberta-large	560M	82.6

How to use

Requirements

Since transformers only supports the ModernBERT architecture from version 4.48.0.dev0, use the following command to get the required version:

pip install "git+https://github.com/huggingface/transformers.git@6e0515e99c39444caae39472ee1b2fd76ece32f1" --upgrade

Install FlashAttention to accelerate inference performance

pip install flash-attn==2.7.2.post1

for item in texts:
