Scientists create tool to explore billions of social media messages, potentially predict political and financial turmoil

The tool — called the Storywrangler — gathers phrases across 150 different languages, analyzing the rise and fall of ideas and stories, each day, among people around the world. The Storywrangler quantifies collective attention.
