Real-time sentiment analysis plays a pivotal role in the realm of Big Data. As people actively share their views and opinions on platforms like Facebook, a wealth of textual information is generated in real time. By analysing this data, we gain insights into public sentiment, political decisions, and public opinion. Organisations can leverage sentiment analysis to monitor brand experiences, customer sentiments, and campaign performance. It’s a powerful tool for understanding how people feel about specific subjects, making it essential in today’s data-driven landscape.
