Introduction

In recent years, with the rise of e-commerce platforms and online shopping, the importance of product reviews has significantly increased. Consumers rely heavily on product reviews to make informed purchasing decisions, as these reviews provide valuable insights into the quality, features, and overall satisfaction of a product. Sentiment analysis of product reviews plays a crucial role in understanding consumer opinions, sentiments, and preferences towards different products.

This research focuses on utilizing machine learning techniques to analyze and extract sentiment from product reviews. Machine learning algorithms have shown great potential in sentiment analysis tasks, as they can automatically classify the sentiment of reviews as positive, negative, or neutral. By applying machine learning to product reviews, companies can gain valuable insights into customer perceptions, identify areas for improvement, and ultimately enhance customer satisfaction and loyalty.
