Search Giant Baidu Gives a Peek at its Latest Work on Artificial Intelligence

Baidu, the world's No. 3 force in online advertising after Google and Facebook, sees artificial intelligence as the next big thing. And it's using AI to power advertising, voice recognition technology and self-driving cars. During its annual conference Thursday in Beijing, the search giant announced news on the autonomous vehicle front, saying it had won clearance from the California Department of Motor Vehicles to test its cars there. It also signed a partnership with U.S. chip-maker Nvidia to work on self-driving cars together. Despite all the investment on futuristic projects, Baidu got nearly 93% of its revenue in the last quarter from online marketing.
