Sentiment Analysis
From Wikipedia “Sentiment analysis or opinion mining refers to the application of natural language processing, computational linguistics, and text analytics to identify and extract subjective information in source materials.”
Sentiment analysis is used in the MyHalo.org framework to connect a Twitter user’s timeline to an ODISS deployment – that is, meta data describing the content on the display. If you tweet “I Love Beer” and a beer advert exists on the display, this personalises the display.
