## Overview

This repository is a research project for estimating sentiment in tweets about COVID-19. Its visible workflow ends at reviewing results in Main.ipynb; the tree also identifies four separate model notebooks (SRN, LSTM, DistilBERT, and XLNet) and several CSV corpus variants. The README does not document which files each notebook reads or how the model notebooks relate to Main.ipynb, and no source excerpts are available, so those connections are left unspecified.

Main entry points: [`Main.ipynb`](https://github.com/lexian-6/sentiment-analysis-towards-covid-19-on-twitter/blob/main/Main.ipynb) (Research notebook)
