eevvgg/sentimenTw-political

This model is a fine-tuned version of multilingual model cardiffnlp/twitter-xlm-roberta-base-sentiment. Classification of text sentiment into 3 categories: negative, neutral, positive. Fine-tuned on a 2k sample of manually annotated Reddit (EN) and Twitter (PL) data.

• Developed by: Ewelina Gajewska as a part of ComPathos project: https://www.ncn.gov.pl/sites/default/files/listy-rankingowe/2020-09-30apsv2/streszczenia/497124-en.pdf

• Model type: RoBERTa for sentiment classification

• Language(s) (NLP): Multilingual; finetuned on 1k English text from Reddit and 1k Polish tweets

• License: [More Information Needed]

• Finetuned from model: cardiffnlp/twitter-xlm-roberta-base-sentiment

Uses

Sentiment classification in multilingual data. Fine-tuned on a 2k English and Polish sample of social media texts from political domain. Model suited for short text (up to 200 tokens) .

How to Get Started with the Model

from transformers import pipeline

model_path = "eevvgg/sentimenTw-political"
sentiment_task = pipeline(task = "text-classification", model = model_path, tokenizer = model_path)

sequence = ["TRUMP needs undecided voters",
            "Oczywiście ze Pan Prezydent to nasza duma narodowa!!"]
            
result = sentiment_task(sequence)
labels = [i['label'] for i in result] # ['neutral', 'positive']
