Natural Language Processing (NLP) in Sentiment Analysis and Social Media Monitoring

Natural Language Processing (NLP) plays an essential role in extracting meaningful information from unstructured text data, especially in sentiment analysis, which focuses on identifying and classifying opinions expressed in textual data. The growing use of social media platforms has resulted in massive amounts of data being generated daily, offering both opportunities and challenges for businesses, governments, and researchers seeking to understand public opinions, consumer behavior, and societal trends. This research paper explores the application of NLP techniques in sentiment analysis, particularly in the context of social media monitoring. The paper delves into the evolution of sentiment analysis models, examines different methodologies used in social media monitoring, discusses the challenges encountered, and evaluates the real-world applications and effectiveness of NLP in social media sentiment analysis. The study also presents results from an empirical analysis of sentiment analysis models on social media data.
