Optimizing the Global Circulation and Soft Power Enhancement of Huangmei Opera Using a Hypergraph Attention Model

This study reinterprets the global spread of Huangmei Opera as a cultural experiment driven by a "modified-gravity hyper-edge attention" topology. The findings show that when the cultural-similarity weight (α) exceeds 0.5, the betweenness centrality of Southeast Asian nodes increases by 40%, revealing a non-linear tipping point in soft power.
