[ad_1]

Introduction:

In recent years, there has been an exponential growth in the amount of customer reviews available online for various products and services. These customer reviews provide valuable insights into the quality of products and services, allowing businesses to improve their offerings and better meet the needs of their customers. Sentiment analysis, a subfield of natural language processing, has emerged as a powerful tool for analyzing customer reviews to extract and quantify opinions, emotions, and attitudes expressed by customers.

This thesis focuses on sentiment analysis of customer reviews for product quality control using text mining and deep learning techniques. The primary goal of this research is to develop a framework that can automatically analyze large volumes of customer reviews to identify patterns and trends related to product quality. By leveraging text mining and deep learning algorithms, this framework aims to provide businesses with actionable insights that can help them make data-driven decisions to enhance product quality and overall customer satisfaction.
