BERTweet-large-sexism-detector

This is a fine-tuned model of BERTweet-large on the Explainable Detection of Online Sexism (EDOS) dataset. It is intended to be used as a classification model for identifying tweets (0 - not sexist; 1 - sexist).

More information about the original pre-trained model can be found here

Our model accuracy was 89.72 using the test set and 86.13 F1-score.

Classification examples:

Prediction	Tweet
sexist	Every woman wants to be a model. It's codeword for "I get everything for free and people want me"
not sexist	basically I placed more value on her than I should then?

How to use

from transformers import AutoModelForSequenceClassification, AutoTokenizer,pipeline
import torch
model = AutoModelForSequenceClassification.from_pretrained('NLP-LTU/bertweet-large-sexism-detector')
tokenizer = AutoTokenizer.from_pretrained('NLP-LTU/bertweet-large-sexism-detector') 
classifier = pipeline("text-classification", model=model, tokenizer=tokenizer)
prediction=classifier("Every woman wants to be a model. It's codeword for 'I get everything for free and people want me' ")
# label_pred = 'not sexist' if prediction == 0 else 'sexist' 

print(prediction)

our system rank 10 out of 84 teams, and our results on the test set was:
