Abstract: After years of development, the National Cultural Big Data System has entered a large-scale implementation phase, establishing a digital infrastructure supported by a national cultural private network, cultural data service platforms, and multi-level trading centers. However, technical bottlenecks such as data identification, secure circulation, and trustworthy applications of large models still need to be overcome. It is recommended that computer professionals focus on research directions including cultural big data identification and resolution, private network data security, rights confirmation and trading mechanisms, cultural big models, and immersive VR/XR research, so as to collectively serve the national cultural digitization strategy.
