## FAQ
### What is text sentiment analysis and how does it work?

Text sentiment analysis uses natural language processing (NLP) and machine learning to automatically determine the emotional tone of written content. Our system analyzes word choice, context, phrases, and linguistic patterns to classify text as positive, negative, or neutral with a confidence score.

### What is the difference between polarity and sentiment score?

Polarity indicates the direction of sentiment (positive, negative, neutral), while the sentiment score (0-1) measures intensity. A score of 0.9 with positive polarity indicates strongly positive content, while 0.5 suggests mildly positive or mixed sentiment.

### How accurate is your sentiment analysis across different topics?

Our models achieve 85%+ accuracy across general news categories, with specialized training for business, politics, technology, and entertainment content. Accuracy varies by domain—factual business news scores higher than opinion pieces with complex irony or sarcasm.

### Can I analyze sentiment for specific entities within an article?

Yes, our entity-level sentiment analysis identifies how specific brands, people, or organizations are portrayed within articles. An article might be neutral overall but contain positive sentiment about one company and negative about another.

### How do you handle sarcasm, irony, and nuanced language?

Our advanced NLP models are trained to recognize common sarcasm patterns and contextual irony. While no system is perfect with nuanced language, we achieve strong performance by analyzing surrounding context, source characteristics, and topic-specific language patterns.

### Can I use sentiment analysis for stock market predictions?

Many financial firms use news sentiment as one input for trading models. Our API provides real-time sentiment data that can be correlated with market movements, though we recommend combining sentiment signals with other fundamental and technical analysis.

### Does sentiment analysis work for non-English content?

Yes, our sentiment models support 60+ languages with language-specific training. Each model understands cultural nuances and language-specific expressions that affect sentiment interpretation, ensuring accurate analysis across global news sources.

### How can I build sentiment trend reports over time?

Use our time-series endpoints to aggregate sentiment data by hour, day, week, or month. Track how sentiment around topics, brands, or events evolves, and correlate changes with specific news events or campaigns.
