China has built around 120,000 high-quality datasets as the country continues to enhance its supply of high-quality data, according to the National Data Administration on Saturday. By the end of June, high-quality datasets in various fields, such as scientific research, industrial manufacturing, and healthcare, had reached a total volume of more than 1,565 petabytes, an increase of over 60 per cent from the end of the first quarter. This volume is equivalent to approximately 547 times the total digital resources held by the National Library of China. Seven pilot cities for data annotation, including Chengdu in Sichuan Province, Shenyang in Liaoning Province, Hefei in Anhui Province, and Changsha in Hunan Province, recorded an annotation data scale exceeding 119 petabytes, absorbing around 140,000 workers in the data annotation sector.
