Sentiment Analysis
NLP technique that determines the emotional tone of text - positive, negative, or neutral. Used for analysing customer feedback, social media, and reviews.
In-Depth Explanation
Sentiment analysis (opinion mining) automatically determines the emotional tone expressed in text. It's one of the most widely used NLP applications in business.
Sentiment analysis levels:
- Document-level: Overall sentiment of entire text
- Sentence-level: Sentiment per sentence
- Aspect-based: Sentiment toward specific features/aspects
- Fine-grained: Beyond positive/negative to specific emotions
Common approaches:
- Lexicon-based: Using sentiment dictionaries
- Machine learning: Training classifiers on labelled data
- Deep learning: Neural networks, transformers
- LLM-based: Using GPT/Claude for nuanced analysis
Challenges:
- Sarcasm and irony detection
- Context-dependent meaning
- Domain-specific language
- Comparative statements
- Implicit sentiment
