Introduction
Social media has become an integral part of our daily lives, enabling people to express their opinions, thoughts, and emotions in real-time. With the vast amount of textual data generated on social media platforms, there is a need for techniques to analyze and understand the sentiment expressed by users. Natural Language Processing (NLP) is a field of study that focuses on the interaction between computers and human language. Sentiment analysis, a subfield of NLP, aims to identify and extract subjective information, such as opinions, attitudes, and emotions, from text data.
This thesis explores the application of NLP for sentiment analysis on social media data. The focus is on utilizing NLP techniques to automatically categorize the sentiment expressed in social media posts, comments, and reviews. By analyzing sentiment on social media, businesses can gain valuable insights into customer opinions, market trends, and brand perception.
