Restaurant Review System

Restaurant Review System is a Flask-based web application that allows restaurant owners to analyze and visualize customer reviews. This platform leverages natural language processing (NLP) techniques using the Natural Language Toolkit (NLTK) and TextBlob in Python. The system enables users to perform sentiment analysis on individual reviews or upload a text file containing multiple reviews for comprehensive analysis. The user-friendly interface ensures easy navigation and understanding of the sentiment analysis results, which are presented through interactive visualizations.

The user interface is designed with simplicity in mind, utilizing Bootstrap CSS to ensure a clean and responsive design.
