Construction and Application of a Digital Platform for Charitable Cultural Resources Integrating <scp>VR</scp> Technology and <scp>BiGRU</scp>

ABSTRACT As an important spiritual driving force to promote the development of public welfare undertakings, charity culture is currently facing challenges such as lack of professional talents and inefficient resource management. The purpose of this research is to build a digital platform of charity cultural resources that integrates virtual reality technology and bidirectional gated circulation unit network, so as to solve the problems of low efficiency of charity cultural information processing, insufficient interaction, and weak public cognition. By introducing a sentence‐level attention mechanism and a relationship perception enhancement module, the bidirectional gated cyclic unit network model is improved, and the entity extraction and relationship mining capabilities of the charity culture knowledge map are optimized. Combine virtual reality technology to realize dynamic visual display of cultural resources to improve platform performance. In the initial stage of the pattern, the growth rate of F 1 was very fast; then the growth rate slowed down, and finally stabilized, with good generalization performance. At 80% CPU occupancy, the response time of the system did not change by more than 0.18 s. With 500 and 1000 parallel users respectively, the communication efficiency of the platform reached 98.37%, demonstrating good signal transmission and communication performance. However, the hardware environment of the digital platform constructed in this study may limit its popularity, and the real‐time update and maintenance of the knowledge graph are faced with challenges.
