"Good morning, welcome to the Practice of Monitoring and Evaluation of Big Data in Scientific and Technological Innovation."

The audience listened to the voice and looked at the empty stage until the voice introduced itself, "I'm a virtual host developed by L'ontologie. My name is Xiaoben."

It was the beginning of a conference which was held at Tsinghua University on Dec 18 that focused on the monitoring and evaluation of big data in scientific and technological innovation.
