Sentiment analysis has become an essential tool for understanding user opinions and emotions on social media platforms. This study focuses on analyzing Instagram data, a widely used platform where users share multimedia content alongside textual captions and comments. The primary objective is to classify sentiments in user-generated content as positive or negative, providing valuable insights into public opinion and emotional trends. The process begins with data collection from Instagram, followed by preprocessing to remove noise, normalize text, and address inconsistencies in the content. Feature extraction is then conducted to identify elements indicative of user sentiment. Natural Language Processing (NLP) techniques and machine learning algorithms are employed, with Logistic Regression (LR) serving as the benchmark model due to its simplicity and effectiveness. To address the challenges posed by Instagram’s multimedia-rich content, the performance of various models is evaluated, ensuring robust sentiment classification. A key feature of this study is the development of an intuitive user interface, designed to allow users to input reviews and instantly receive sentiment predictions alongside actionable insights. The interface is user-friendly and visually appealing, emphasizing accessibility and practicality for real-world use cases. By providing a platform for analyzing and interpreting sentiments, this study highlights the effectiveness of machine learning in improving customer engagement, refining marketing strategies, and understanding audience behavior. It contributes to advancements in social media sentiment analysis, offering solutions to unique challenges and enabling businesses to derive meaningful insights from Instagram’s user-generated content.
