Watson News Explorer makes use of Watson Discovery News, which scans 300,000 English-language news articles daily and uses natural language processing to convert them into a searchable network of topics. Natural language processing is a branch of artificial intelligence that combines linguistics with computing power. Natural language processing is at work in language translation apps, grammar checkers, and computerized personal assistants like Siri and Alexa. This macroscope, designed by Steven Ross, Timothy Stutts, Megan Monroe, and Mauro Martino of IBM’s Visual AI Lab, uses natural language processing to identify and link entities like names, locations, companies, and organizations.

The macroscope offers four ways to dive into the news: a world map, a timeline, a word cloud, and a network. These visualizations are linked, so that searching in one will highlight connections in the others. You can also search for multiple keywords to reveal links that connect seemingly unrelated topics.
