Forty-nine advanced scientific and technology achievements were awarded at the ongoing Big Data Expo in Guiyang, Guizhou province, on Wednesday, representing the latest technologies in the big data industry worldwide.

The honors, which included seven "black technologies", 10 new technologies, 20 new products, seven business modes and five sci-tech achievements in fighting the pandemic, were approved by the National Office for Science and Technology Awards, the only social technology award in the field of big data nationwide, according to a Xinhua report.

This year's selection, which began across the world on Feb 4, received 560 nominations from big data and related industries, with 49 technologies ultimately voted by leading experts of the industry after several rounds of evaluation.

As the world is still affected by the COVID-19 pandemic, the awards set a special sector for sci-tech fighting against the pandemic and unveiled achievements that have made outstanding contributions in the prevention, control and treatment of the pandemic by using big data-related technologies.

Black technology award winners, including Huawei, Moviebook, Kugou, Ant group, Tencent, and Qi-Anxin Technology, showcased their latest technologies to the audience during the award ceremony, Guiyang Daily reported.

The China International Big Data Expo 2021, which runs until Friday in Guiyang, Guizhou province, is an event widely acknowledged as a world-class platform, serving to share the latest achievements in the big data industry.
