Fixing paper assignments

  1. Please select all papers that belong to the same person.
  2. Indicate below which author they should be assigned to.
Provide a valid ORCID iD here. This will be used to match future papers to this author.
Provide the name of the school or the university where the author has received or will receive their highest degree (e.g., Ph.D. institution for researchers, or current affiliation for students). This will be used to form the new author page ID, if needed.

In the digital age, social media platforms like Twitter serve as an extensive repository of public discourse, including instances of sexism. It is important to identify such behavior since radicalized ideologies can lead to real-world violent acts. This project aims to develop a deep learning-based tool that leverages a combination of BERT (both English and multilingual versions) and GraphSAGE, a Graph Neural Network (GNN) model, alongside sentiment analysis and natural language processing (NLP) techniques. The tool is designed to analyze tweets for sexism detection and classify them into five categories.
