Why IBM Watson is interested in Twitter data and supporting developers

IBM Watson can do much more than answer questions on Jeopardy. Earlier this month, the artificial intelligence system created a movie trailer. It also powers driverless cars and is helping doctors with cancer care and research. Watson is IBM's bet on the next era of computing that is built to understand, reason, learn and interact, according to IBM Watson's Chief Marketing Officer Steve Gold. "It's not speech recognition like Siri, not speech synthesis like Alexa, but actually understanding human languages," Gold told Mashable.
