I recently bought a string of 50 individually addressable RGB LEDs from Embedded Adventures and so had to decide what to do with them. I decided it would be festive if they could reflect Twitter’s current feeling about Christmas.
So I started Googling sentiment analysis and quickly discovered that Stanford University’s Natural Language Processing Group has released the source and data for their sentiment analyser. When fed a sentence it outputs one of “Very negative”, “Negative”, “Neutral”, “Positive” or “Very positive”.
