🎊 PoliBERTweet: Language Models for Political Tweets

Transformer-based language models pre-trained on a large amount of politics-related Twitter data (83M tweets). This repo is the official resource of the following paper.

• PoliBERTweet: A Pre-trained Language Model for Analyzing Political Content on Twitter, LREC 2022.

📚 Data Sets

The data sets for the evaluation tasks presented in our paper are available below.

• Poli-Test & NonPoli-Test - [Download]
• Stance Data Sets - [Download] [Paper] [Github]

🚀 Pre-trained Models

All models are uploaded to my Huggingface 🤗 so you can load model with just three lines of code!!!

• PoliBERTweet (83M tweets) - Feel free to fine-tune this to any downstream task 🎯
• PoliBERTweet-small (5M tweets)

⚙️ Usage

We tested in pytorch v1.10.2 and transformers v4.18.0.

• To fine-tune our models for a specific task (e.g. stance detection), see the HuggingFace Doc
• Please see specific model pages above for more usage details. Below is a sample use case.

1. Load the model and tokenizer

from transformers import AutoModel, AutoTokenizer, pipeline
import torch

# Choose GPU if available
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")

# Select mode path here
pretrained_LM_path = "kornosk/polibertweet-mlm"

# Load model
tokenizer = AutoTokenizer.from_pretrained(pretrained_LM_path)
model = AutoModel.from_pretrained(pretrained_LM_path)

2. Predict the masked word

# Fill mask
example = "Trump is the <mask> of USA"
fill_mask = pipeline('fill-mask', model=pretrained_LM_path, tokenizer=tokenizer)

outputs = fill_mask(example)
print(outputs)

3. See embeddings

# See embeddings
inputs = tokenizer(example, return_tensors="pt")
outputs = model(**inputs)
print(outputs)

# OR you can use this model to train on your downstream task!
# please consider citing our paper if you feel this is useful :)

4. Fine-tune to a downstream task like stance detection

See details in the HuggingFace Doc.
