Investigating the use of natural language processing for automated sentiment analysis of social media posts – Complete Phd and Masters Thesis

[ad_1]

Introduction

Social media has become an integral part of our daily lives, with millions of users sharing their thoughts, opinions, and emotions online. As a result, there is an abundance of data available for analysis, presenting researchers with an opportunity to gain insights into public sentiment on various topics. In recent years, natural language processing (NLP) has emerged as a powerful tool for analyzing text data, enabling researchers to automatically extract and classify sentiment from social media posts.

This thesis aims to investigate the use of NLP for automated sentiment analysis of social media posts. By leveraging machine learning algorithms and linguistic techniques, this study seeks to develop a framework that can accurately assess the sentiment expressed in online content. The findings of this research have the potential to inform businesses, policymakers, and researchers about public opinions and trends on social media platforms.
