Frequently asked questions

What's the difference between sentiment and emotion detection?

Sentiment analysis classifies text as positive, negative, or neutral on a single polarity scale. Emotion detection identifies specific feelings (joy, anger, sadness, fear, etc.). Advanced tools like IBM Watson and Lexalytics detect both, whilst basic APIs focus only on sentiment polarity.

How much does sentiment analysis typically cost?

Pricing varies widely: cloud APIs range from £0.0001 per request (ParallelDots, Clarifai) to £1 per 1,000 requests (Google, Azure). Specialised platforms like MonkeyLearn cost £300+ monthly, whilst enterprise solutions charge custom rates. Open-source (Hugging Face) is free but requires engineering.

Can these tools handle multiple languages?

Most major platforms support 10-30+ languages. Google Cloud Natural Language and IBM Watson excel here with 10+ language support. However, accuracy varies by language; English generally has the highest precision, whilst less-resourced languages may be 5-10% less accurate.
