PRS-I : AI-Based Product Review System

Introduction

This project is a cutting-edge product review analysis tool leveraging Natural Language Processing (NLP) to assess the sentiment of product reviews. The backend is built with Django, while the frontend is crafted using vanilla HTML, CSS, and JavaScript. The NLP model, developed with the NLTK library, predicts the sentiment of product reviews.

Features

  • Product Link Entry: Users can input a product link, and the review text is automatically extracted from product pages on platforms such as Amazon and Flipkart.
  • Sentiment Analysis: The extracted review text undergoes analysis to determine its sentiment.
  • Sentiment Display: The sentiment analysis results are presented to the user, accompanied by a summarized review and a visual representation of the sentiment.
  • Personalized Reviews: Users can receive personalized reviews based on their past preferences and review history.

Review Scope

The AI product reviewer harnesses NLP techniques to:

  • Extract and process review text from various product pages.
  • Analyze and predict the sentiment of the reviews.
  • Provide users with comprehensive summaries and visual sentiment representations.
  • Offer personalized review recommendations based on user history.

Components

Chrome Extension (Entry Point)

The Chrome extension serves as the entry point, allowing users to effortlessly extract review text from product pages on major e-commerce platforms.

Main Website

  • User Authentication: Secure authentication for managing user accounts.
  • User History: Maintains a detailed history of analyzed reviews for each user.
  • Personalized Reviews: Delivers personalized review summaries and suggestions based on user preferences and past interactions.

REST API

The REST API connects the Chrome extension to the backend, handling:

  • Requests for review text extraction.
  • Communication with the NLP model for sentiment analysis.
  • Storage and retrieval of user history, authentication data, and personalized review data.

NLP Model

The NLP model, developed using the NLTK library, processes review texts to:

  • Clean and tokenize the text
  • Analyze sentiment using pre-trained models and custom algorithms
  • Generate sentiment scores and summaries for the reviews.

Database

A robust database system is used to:

  • Store user authentication details.
  • Maintain a history of analyzed reviews for each user.
  • Save sentiment analysis results, summaries, and personalized review data.
