Introduction

In this article, we will explore the development process and functionality of an Amazon review generator. The review generator is a project undertaken by a team of developers and aims to provide a tool that can generate realistic reviews for Amazon products. With the help of natural language processing and machine learning, the review generator is capable of producing reviews that closely Resemble those written by actual users. We will dive into the details of the project, discuss its possible uses, and explain the steps involved in creating the review generator. So let's get started!

Project Overview

Team Members

The project was developed by a team comprising Jonathan (Product Manager and Back-End Developer), Srishti (Model Trainer and Front-End Developer), Kai (Front-End Developer and Model Contributor), Ariel (Front-End Developer), and Anatulia (Back-End Engineer). Each team member played a crucial role in different aspects of the project.

Project Description

The main objective of the review generator project was to Create a tool that could generate realistic Amazon reviews. The team aimed to develop a system that would help individuals and companies write initial reviews for their products, as well as provide the ability to generate negative reviews if desired. By utilizing machine learning models and natural language processing techniques, the team developed a generator that could mimic the writing style and sentiment of real Amazon reviews.

Possible Uses of the Review Generator

The review generator can serve a variety of purposes, some of which are listed below:

As a Start for New Products

The review generator can be a useful tool for launching new products on Amazon. Instead of having an empty page with no reviews, the review generator can generate starting reviews to make the product listing look more appealing to potential buyers.

For Companies Needing Initial Reviews

Companies, especially small businesses, often struggle to obtain initial reviews for their products. The review generator can help by providing them with realistic reviews to showcase on their product pages. This can increase the credibility of their products and attract more customers.

Writing Negative Reviews

In some cases, individuals or companies may wish to write negative reviews. The review generator can be used to generate realistic negative reviews for products, allowing users to express their dissatisfaction or critique a particular item.

Creating the Review Generator

The review generator involved several steps to achieve its functionality. Let's take a closer look at each of these steps:

Data Set Selection

To train the review generator, the team needed a suitable data set of electronic product reviews. They found a data set called "2018 Electronics Reviews" on Kaggle, which contained approximately 14,000 reviews from different electronics products. The team performed web scraping to obtain additional reviews and cleaned the data set by removing stop words and separating it into positive and negative reviews.

Training the Model

The team utilized Python 3 and the GPT-2 (gp2) model for training the review generator. Initially, the model was trained on the original data set without categorizing it into positive or negative reviews. Hyperparameters were adjusted to ensure that the generated reviews seemed more human-like and less robotic. However, some challenges were encountered, such as the model occasionally mixing up terminologies for different products. Despite this, the team managed to improve the model's performance by addressing these issues.

Extending the Idea

To enhance the functionality of the review generator, the team decided to extend the concept beyond electronics reviews. The idea was to allow the model to generate positive or negative reviews Based on user selection. The reviews were separated into positive and negative lists using text blob and two separate models were trained with these lists.

Creating the Website

After completing the model training, the team proceeded to create a website for the review generator. They used a template and customized it to match the desired aesthetic and branding, including the incorporation of the Amazon logo. Once the website was developed, the review generator was deployed for public access.

Difficulties Faced

While developing the review generator, the team encountered several challenges. Let's discuss some of these difficulties:

Model Training

Training the machine learning model for the review generator was a time-consuming process. Initially, the results generated by the model did not make much Sense and required retraining. Each training session took more than 20 minutes, demanding patience and careful evaluation to improve the model's performance.

Debugging

Like any significant project, the review generator faced debugging challenges. The team encountered various errors while developing the system, which required thorough troubleshooting and problem-solving. Addressing each error consumed a significant amount of time and effort.

Sentiment Analysis

To generate positive and negative reviews, sentiment analysis was essential. Analyzing thousands of reviews to determine their sentiment and categorizing them accordingly was a time-consuming task. The team had to exercise patience while processing the data set to differentiate between positive and negative reviews.

Demo of the Review Generator

To provide a better understanding of the review generator's functionality, let's take a look at some examples of the reviews it can generate. We will showcase both positive and negative review examples.

Positive Review Examples

1. Review for Speakers:
   • "Speakers can be cranked up and higher in the Chorus—otherwise great for the price."
2. Review for Computer:
   • "The computer is awesome; only wish that the next model would have been available at this time."
3. Review for Camera:
   • "The camera fits my Olympus easier perfectly. It feels great in your HAND, too, with a comfortable weight."

Negative Review Examples

1. Review for Speakers:
   • "Speakers have been an absolute disappointment. Horrible quality; amazingly, it's only two bucks, so I'll give it zero stars."
2. Review for Computer:
   • "Computerism is just a matter of personal preference because it is so narrow. It is hard to make a screen protector, and I even spotted areas of poor quality on the screen, which only came off on the left side."

Limitations and Future Plans

The review generator is designed specifically for Amazon electronics reviews and may not provide accurate results for other products or categories. In the future, the team plans to expand the review generator's capabilities by incorporating different products and platforms. By training the model on a more diverse data set, the review generator can be enhanced to generate reviews for a wide range of products, catering to various industries.
