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.
