Ever wondered what the world is talking about? Grapevine is an online system that conducts large scale data analysis on the social media collective, extracting and distilling information in real time from millions of blog posts, thousands of tweets, news items, etc. It automatically identifies stories, emerging events, popular or surprising entities narrowed down to any demographic of interest (e.g., "What are male teens talking about in Toronto?" or "What were financiers in Texas blogging about during the previous week?"). Stories can be interactively explored in a variety of ways, such as modifying their scope, obtaining related content and examining their temporal evolution.
