GUIYANG, May 27 (Xinhua) -- Guizhou Berkeley Big Data Innovation Research Center (GBIC) launched two public welfare campaigns using big data technology to benefit left-behind children and elderly people.

The center announced the campaigns on Saturday during the 2018 China international big data industry expo in Guiyang, capital city of southwest China's Guizhou Province.

The center will use big data to perform online diagnosis of 100,000 cataract patients in Guizhou. The program, which lasts three years, aims to make up for the lack of professional ophthalmologists in remote and poor counties in the province, the center said.

Another program targets 40,000 left-behind children whose parents are migrant workers. The center will develop software to test the children's psychological health and learning abilities, and offers remote education functions. The program is also designed to help 4,000 elderly people in Guizhou.

The GBIC was jointly launched by Msweekydata, in cooperation with the University of California at Berkeley, electronics department of the Ministry of Industry and Information Technology, and the Guiyang City government. The center targets regional social problems using big data.
