Thesis Abstract

Abstract
Social media platforms have become integral parts of modern communication, providing vast amounts of data that can offer valuable insights into public opinion and sentiment. Sentiment analysis, a subfield of natural language processing, aims to extract and analyze sentiments expressed in text data. This study focuses on applying machine learning algorithms for sentiment analysis in social media data to uncover trends, patterns, and sentiments among users. The research begins with a comprehensive review of the literature, exploring existing studies on sentiment analysis, machine learning algorithms, and their applications in social media data analysis. The study then outlines the research methodology, detailing the data collection process, preprocessing techniques, feature extraction methods, and the selection and implementation of machine learning algorithms. The findings of the study are discussed in Chapter Four, where the results of the sentiment analysis on social media data are presented and analyzed. The discussion covers the performance of different machine learning algorithms in sentiment classification, insights gained from the analysis, and potential implications for real-world applications. In conclusion, this thesis highlights the significance of applying machine learning algorithms for sentiment analysis in social media data. By leveraging these technologies, organizations and researchers can gain valuable insights into public opinion, consumer behavior, and trends in various industries. The study contributes to the existing body of knowledge on sentiment analysis and machine learning applications in social media data analysis, paving the way for further research and practical implementations in the field.

Thesis Overview

The project titled "Applying Machine Learning Algorithms for Sentiment Analysis in Social Media Data" focuses on utilizing machine learning algorithms to analyze sentiments expressed in social media data. Social media platforms have become integral parts of modern communication, providing a vast amount of data that can offer valuable insights into public opinion, trends, and sentiments. Sentiment analysis, also known as opinion mining, is a technique that involves the use of natural language processing, text analysis, and computational linguistics to identify and extract subjective information from text data. The research aims to explore the application of machine learning algorithms in sentiment analysis to enhance the understanding of sentiments expressed in social media data. By leveraging the power of machine learning, the study seeks to develop accurate and efficient models that can automatically classify and analyze sentiments expressed in textual content from social media platforms such as Twitter, Facebook, and Instagram. The project will begin with a comprehensive literature review to examine existing research in sentiment analysis, machine learning algorithms, and their applications in social media data analysis. This review will provide a solid foundation for understanding the current state-of-the-art techniques and methodologies in the field. The research methodology will involve data collection from various social media sources, preprocessing of the collected data, feature extraction, model training using machine learning algorithms such as Support Vector Machines, Naive Bayes, and Neural Networks, and evaluation of the developed models based on metrics such as accuracy, precision, recall, and F1 score. The findings of the study will be discussed in detail, highlighting the performance of different machine learning algorithms in sentiment analysis tasks. The discussion will also include the identification of challenges and limitations encountered during the research, as well as potential areas for future research and improvement. In conclusion, the project aims to contribute to the field of sentiment analysis by demonstrating the effectiveness of machine learning algorithms in analyzing sentiments in social media data. The insights gained from this research can have significant implications for various applications, including market research, brand management, customer feedback analysis, and public opinion monitoring in the era of digital communication.
