Introduction

Sentiment analysis is a technique used to extract and analyze subjective information from text data, with the aim of determining the sentiment expressed in a given piece of text. In recent years, sentiment analysis has gained significant traction in various fields, including marketing, customer service, and social media monitoring, as it enables organizations to gain valuable insights into the opinions, emotions, and attitudes of their customers.

In the context of product reviews, sentiment analysis can provide valuable information to businesses about the overall sentiment towards their products, identify common themes and issues raised by customers, and monitor changes in sentiment over time. Through the use of text mining techniques, large volumes of product reviews can be analyzed efficiently and effectively, allowing businesses to make data-driven decisions to improve their products and services.

This research project aims to investigate sentiment analysis of product reviews using text mining techniques, with a focus on understanding the sentiment expressed in customer reviews of various products. By employing advanced text mining algorithms, this study seeks to uncover patterns, trends, and insights from a large dataset of product reviews, providing valuable information to businesses for decision-making purposes.
