From August 15 to 16, the 220th “Science and Technology Frontier Forum” organized by the Academic Division of the Chinese Academy of Sciences (CAS) was held at Nanjing University’s Suzhou Campus. The theme of this forum is “Data Science and Applications.” Tan Tieniu, Chair of NJU CPC Council and Academician of the CAS, as well as CAS academicians Guo Huadong, Xu Zongben, and Mei Hong served as the Executive Chairs of the forum.
Twenty academicians and seventy-four experts from domestic and international universities and research institutions gathered in Suzhou to conduct in-depth exchanges on fundamental theories, key technologies, innovative applications, and safety governance in data science. The forum provided suggestions for building China’s data science discipline, achieving breakthroughs in core technologies, and promoting industrial innovation and development.
In his welcome speech on behalf of the Forum Organizing Committee and NJU, Tan Tieniu welcomed the attendees. He noted that the CAS Academic Division’s “Science and Technology Frontier Forum”, established in 2011, is a high-level academic series activity advocating academic democracy and diverse perspectives. Since the 18th National Congress of the Communist Party of China, General Secretary Xi Jinping has delivered a series of important remarks on the development of data science and technology. Notably, at the founding conference of the International Data Organization, he sent a congratulatory letter, emphasizing that the world is accelerating into the intelligent era, where data is becoming increasingly important as both a basic resource and an innovation driver. He stressed the need for a digital economy based on data and the importance of ensuring security throughout data governance processes. These remarks have provided fundamental guidance for the development of data science and technology. The CAS Academic Division’s choice of “Data Science and Applications” as the theme of this forum aims to implement the General Secretary’s directives and carries significant practical importance. Tan expressed hope that the attending experts would engage in extensive discussions, contributing their wisdom and fostering an open, equal atmosphere to jointly explore frontier issues in data science and further advance related disciplines and technologies.
CAS Academician Ding Chibiao delivered a speech on behalf of the CAS. He outlined CAS’s “AI for Science” initiative, which aims to embrace paradigm shifts in scientific research brought about by artificial intelligence. This initiative has a “1+M+N” framework: “1” refers to the establishment of a universal foundation; “M” involves creating about ten major strategic areas empowered by AI; and “N” refers to supporting thousands of scientific application scenarios. In scientific data, CAS has undertaken several national tasks, such as building national scientific data centers, public service platforms, and scientific corpora, while actively forming a data system comprising a general center, domain-specific centers, and operational centers. CAS aims to continue adhering to open collaboration by working with domestic and international universities and research institutions to promote the coordinated and healthy development of AI for Science and data science applications.
Data has now become a crucial production factor. Data science is playing an increasingly important role in supporting the development of the digital economy, driving changes in scientific research paradigms, and enhancing the modernization of national governance. The forum was divided into three themes: “Data Theory and Algorithms” “Data Applications and Systems” and “Data Security and Governance”, closely aligned with national strategies of building digital China, developing data resource applications, and advancing AI innovation. The forum featured 12 academician-led reports and three concentrated discussions, systematically reviewing the current landscape and emerging trends in data science and analyzing key scientific challenges and technological bottlenecks.
