Frequently asked questions

How does sentiment analysis work?
This tool uses the AFINN word list, which assigns a score from -5 (very negative) to +5 (very positive) to over 3,000 common English words. The overall score is the sum of all matched words. The comparative score divides this by the total word count for a normalised result.
Is this accurate for all types of text?
AFINN-based sentiment works best for informal English text like reviews, social media posts, and customer feedback. It may be less accurate for technical, formal, or non-English text, and it does not understand context, sarcasm, or idioms.
What does a score of 0 mean?
A score of 0 means the text is neutral — either no scored words were found, or the positive and negative words balanced each other out.
What is the difference between score and comparative?
The score is the raw total and increases with longer text. The comparative score is the score divided by the word count, so it is comparable between texts of different lengths. Use the comparative score when comparing multiple pieces of text.
