More big data technologies will be widely applied, not only to e-commerce business but also to the booming e-governance sector and civil services, benefiting both citizens and governments, experts and company leaders said Thursday as the Big Data Expo trade show prepared to open in Guiyang, Guizhou province.

The show runs Thursday through Sunday.

A huge IT system and a variety of big data technologies are needed to better govern and serve people from cradle to grave, given that as many as 2,500 kinds of civil services are used during an ordinary citizen's life, said Hu Xiaoming, president of Alibaba Cloud, the cloud computing arm of Alibaba Group Holding.
