Introduction

In recent years, social media has become a crucial platform for people to express their opinions, emotions, and sentiments in response to various events, including crises such as natural disasters, social unrest, and public health emergencies. The vast amount of data generated on social media during such crises presents an opportunity for organizations and authorities to gather real-time information on the public’s sentiment and response to the crisis. Sentiment analysis, a subfield of Natural Language Processing (NLP), has emerged as a powerful tool to extract and analyze sentiment from social media posts.

This research focuses on the application of sentiment analysis using text mining and deep learning techniques to analyze social media posts for crisis response. By harnessing the power of machine learning algorithms, it aims to provide insights into the sentiment of social media users during crises, enabling authorities to better understand public sentiment, identify areas of concern, and respond effectively to mitigate the impact of the crisis.

Thesis Overview

The use of social media for crisis response has gained significant attention in recent years, as it provides a real-time platform for individuals to share information, express emotions, and seek help during emergencies. Sentiment analysis, a technique that involves extracting and analyzing sentiments from text data, has emerged as a powerful tool to understand public sentiment during crises. This thesis focuses on the application of sentiment analysis using text mining and deep learning techniques to analyze social media posts for crisis response.

Chapter 1 provides an introduction to the research topic, discussing the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of terms. Chapter 2 reviews the existing literature on sentiment analysis, social media use in crisis response, text mining and deep learning techniques, applications of sentiment analysis in crisis response, challenges and limitations, previous studies, and theoretical framework for sentiment analysis.

Chapter 3 outlines the research methodology, including research design, data collection and preprocessing, sentiment analysis techniques, deep learning models, evaluation metrics, experimental setup, data analysis, and ethical considerations. Chapter 4 presents a detailed discussion of the findings, including the analysis of sentiment in social media posts during crises, comparison of text mining and deep learning techniques, impact of sentiment analysis on crisis response, insights for decision-making, future research directions, and implications for practice.

Chapter 5 concludes the thesis by summarizing key findings, highlighting contributions to the field, discussing practical implications, addressing limitations, suggesting future research directions, and providing a conclusive statement. The thesis aims to contribute to the growing body of knowledge on sentiment analysis for crisis response, offering insights for researchers, policymakers, and practitioners interested in leveraging social media data for effective crisis management.
