Gravity calculates Interest Graphs for each user, so that they can enjoy dynamic experiences tailored to their interests on sites using Gravity Personalization.
How it works: We calculate what's interesting on the web in real-time. As new content is published across the web or shared on the social web, Gravity crawls, indexes and semantically analyzes each web page, tweet, status update or post. Gravity organizes structured and unstructured content by interest, so that we can calculate trending topics or surface the most viral stories about any topic on demand. Finally, we deliver personalized recommendations to each user based on the topics they engage with most and what's exciting right now.
