Frequently Asked Questions
What is sentiment analysis?
Sentiment analysis (opinion mining) uses natural language processing to identify and extract subjective information from text. It classifies text as positive, negative, or neutral, enabling at-scale understanding of customer opinions, brand perception, and market sentiment.
How accurate is sentiment analysis?
Accuracy varies: simple positive/negative classification achieves 70-90% accuracy depending on domain. Sarcasm, context-dependent language, and mixed sentiments reduce accuracy. Human-level understanding remains challenging, especially for nuanced text.
Can sentiment analysis detect sarcasm?
Detecting sarcasm is one of sentiment analysis's hardest challenges. 'This is just great' could be genuine or sarcastic depending on context. Advanced models use contextual clues, but accuracy is lower than straightforward sentiment. Human review helps for critical applications.
How do you calculate sentiment score?
Common approach: assign scores to positive (+1) and negative (-1) words, weight by intensity, sum, and normalize. Advanced methods use machine learning models trained on labeled data. Score typically ranges from -1 (very negative) to +1 (very positive) or -100 to +100.
What are sentiment analysis use cases?
Key uses: brand monitoring (track social media sentiment), customer feedback analysis (reviews, support tickets), market research (survey responses), product development (feature sentiment), crisis detection (negative sentiment spikes), and competitor analysis.
Why does context matter in sentiment?
The same words mean different things in different contexts. 'Sick' is negative in healthcare but positive in slang. 'Long battery life' is positive; 'long download time' is negative. Context-aware models perform better than bag-of-words approaches.
