ABSTRACT: Sentiment Analysis (SA) has emerged as a cornerstone of modern data analytics, offering sophisticated means to extract subjective information from vast volumes of unstructured text data, such as product reviews, social media content, and customer service interactions. As digital platforms continue to proliferate, understanding consumer sentiment has become crucial for businesses seeking to maintain competitive advantage and foster customer loyalty.

This paper presents an in-depth analysis of key SA methodologies, including traditional lexicon-based approaches, machine learning classifiers (e.g., Support Vector Machines, Naïve Bayes), and state-of-the-art deep learning architectures such as Convolutional Neural Networks (CNNs), Recurrent Neural Networks (RNNs), and Transformer-based models like BERT. The comparative evaluation focuses on their performance, scalability, domain adaptability, and interpretability.

Additionally, this study examines the role of SA in business intelligence, market trend prediction, brand monitoring, and real-time customer feedback systems. It further delves into persistent challenges, such as sarcasm and irony detection, aspect-based sentiment analysis, code-mixed and multilingual data processing, and bias mitigation in algorithmic interpretations.

Ethical considerations—including privacy concerns, data anonymization, and the potential misuse of predictive sentiment models—are critically discussed to ensure responsible implementation of SA technologies.

By synthesizing current methodologies, case studies, and emerging trends, this paper highlights the transformative potential of sentiment analysis in data-driven decision- making. It advocates for collaborative frameworks involving researchers, industry stakeholders, and policy-makers to address technological gaps, enhance model robustness, and promote transparent, equitable use of sentiment analysis across sectors.

Keywords: Sentiment Analysis, Natural Language Processing, Machine Learning, Opinion Mining, Product Reviews.
