Introduction

Social media has become an integral part of our daily lives, providing a platform for individuals to express their thoughts, emotions, and opinions on various topics. In times of crisis, such as natural disasters, public health emergencies, or political unrest, social media plays a crucial role in disseminating information and coordinating response efforts. However, the vast amount of data generated during a crisis can be overwhelming to handle, making it challenging for crisis responders to identify critical information and sentiments from the noise.

Sentiment analysis, a subfield of natural language processing, has emerged as a powerful tool for extracting and analyzing sentiments expressed in social media conversations. By leveraging text mining techniques and machine learning algorithms, sentiment analysis can help identify sentiments of individuals towards a particular crisis, government response, or humanitarian efforts. This can provide valuable insights for crisis managers to understand public perception, sentiment trends, and emerging issues during a crisis.

This thesis will focus on the application of sentiment analysis of social media conversations for crisis management using text mining and machine learning techniques. The study aims to explore the effectiveness of sentiment analysis in understanding public sentiment during a crisis and its potential implications for crisis response strategies. By analyzing sentiments expressed in social media conversations, this research seeks to provide valuable insights for crisis managers to improve decision-making processes and enhance crisis communication strategies.

Thesis Overview

The rapid proliferation of social media platforms has transformed the way information is shared, disseminated, and consumed during crises. In this dynamic and volatile environment, understanding public sentiment and perceptions is crucial for effective crisis management and response. Sentiment analysis, a powerful tool in natural language processing, offers a systematic approach to analyzing and extracting sentiments expressed in social media conversations. By applying text mining and machine learning techniques, sentiment analysis can help crisis managers gain valuable insights into public sentiment, sentiments trends, and emerging issues during a crisis.

This thesis aims to explore the application of sentiment analysis of social media conversations for crisis management using text mining and machine learning techniques. The study will investigate the effectiveness of sentiment analysis in understanding public sentiment during a crisis and its potential implications for crisis response strategies. By analyzing sentiments expressed in social media conversations, this research seeks to provide actionable insights for crisis managers, enabling them to make informed decisions, enhance crisis communication strategies, and improve overall crisis response. Through a comprehensive literature review, rigorous research methodology, and insightful discussion of findings, this thesis will contribute to the growing body of knowledge on sentiment analysis in crisis management and provide valuable insights for researchers, practitioners, and policymakers in the field.
