MixedHow does sentiment analysis work?
This tool uses the AFINN lexicon, a curated list of words rated for sentiment from -5 (most negative) to +5 (most positive). Each word in your text is matched against this lexicon, and the overall sentiment is calculated based on the combined scores.
What is the AFINN lexicon?
AFINN is a sentiment lexicon developed by Finn Arup Nielsen. It contains over 3,000 English words, each assigned a sentiment score. It's widely used for basic sentiment analysis in social media, reviews, and other text data.
How is the sentiment score calculated?
The tool sums the AFINN scores of all recognized words, then normalizes the result to a -1 to +1 scale. Positive scores indicate positive sentiment, negative scores indicate negative sentiment, and scores near zero are neutral.
