De la contraportada

From rule-based systems to deep learning, the author presents everything you need to know about sentiment analysis

As sentiment analysis evolves from simple lexicon matching to sophisticated multimodal deep learning, practitioners need authoritative guidance spanning the field's entire trajectory. Sentiment Analysis in NLP delivers this breadth, covering text-based, aspect-based, multimodal, and implicit sentiment analysis, integrating text, audio, and visual data processing while addressing both theoretical foundations and real-world implementations.

This book examines neural network architectures including CNNs and RNNs for text analysis, transformer models like BERT, and Graph Attention Networks. Dedicated chapters cover attention mechanisms and generative AI for synthetic data generation. Practical applications span product development, social media monitoring, and public health surveillance. Python code, datasets, and a solutions manual support hands-on learning.

Readers will also find:

• Multimodal sentiment analysis techniques integrating text, speech, and image data to interpret emotional content across diverse communication formats
• Transformer-based models and attention mechanisms including BERT and GPT architectures that have transformed state-of-the-art sentiment classification performance
• Real-time context-aware sentiment analysis systems designed for continuous monitoring applications in social media and business intelligence environments
• Ethical considerations addressing data privacy, algorithmic bias, and transparency challenges that practitioners face when deploying sentiment analysis systems
• Case studies demonstrating sentiment analysis applications across customer feedback analysis, public safety monitoring, and healthcare decision support contexts

This reference serves NLP researchers, data scientists, and business intelligence professionals who implement sentiment analysis systems. Graduate students in machine learning and deep learning will find both theoretical depth and practical resources for coursework and research applications.
