Below is a template for a structured and informative README file for your sentiment analysis project. I've included sections on project overview, dataset, model fine-tuning, running evaluations, and additional notes. Please customize it further based on your specific project details. + +--- + +# Sentiment Analysis of Customer Reviews + +## Overview + +This project focuses on sentiment analysis of customer reviews using machine learning techniques. The goal is to fine-tune various models on a customer review dataset, compare their performance, and evaluate pre-built models for sentiment analysis. The project is designed to be executed on CPU, utilizing low-size models for efficiency. + +## Dataset + +The dataset used for this project consists of approximately 20,000 customer comments. The labels assigned to each comment range from -0.9 to 0.9, reflecting a sentiment score. The sentiment scores are mapped to a classification scale resembling a star rating, ranging from 1 star to 5 stars. + +## Model Fine-Tuning + +### Fine-Tuned Model + +The project employs the 'distilbert-base-uncased' model from Hugging Face as the base model for fine-tuning. This model is chosen for its lower size, making it suitable for training and testing on CPU. + +To fine-tune the model, the sentiment labels are transformed into a classification task, converting the sentiment scores into star ratings. The fine-tuning process is implemented in the `evaluation.py` script, providing insights into the model's performance. + +### Pre-Built Model + +Additionally, a pre-built classification model, 'nlptown/bert-base-multilingual-uncased-sentiment,' is included in the evaluation process. This model is specifically fine-tuned for customer reviews. + +## Running Evaluations + +To evaluate the fine-tuned and pre-built models, run the `evaluation.py` script. This script generates confusion matrices for each model, facilitating a comparative analysis of their performance. The confusion matrices offer a visual representation of how well the models classify sentiments across different classes. + +```bash +python evaluation.py +``` + +## Additional Notes + +- Ensure that the required dependencies are installed. Refer to the `requirements.txt` file for details. +- The project is optimized for execution on CPU and utilizes smaller-sized models for efficiency. +- Customize hyperparameters, model architecture, or training settings as needed for your specific requirements. + +Feel free to explore and experiment with different models and datasets to enhance the project's performance. + +--- + +You can copy and paste this template into your README file and further modify it based on any additional information you'd like to include or specific details about your project.
