Research on Broadcasting and Television Image Communication Based on Ethnic Cultural Knowledge Graph

The knowledge graph of ethnic culture, as an emerging way of knowledge representation and organization, has shown great potential and value in the field of broadcasting and television image dissemination. The study first proposes a hybrid optimization method for constructing a knowledge graph of ethnic cultures, which constructs a knowledge graph network structure that includes entities, concepts, attributes, and interrelationships of various ethnic cultures. Then, a radio and television image playback content recommendation model using alternating least squares method and graph neural network is proposed to predict the audience's preference for watching ethnic cultural image content. The results showed that the recommendation method constructed in the study accurately classified ethnic cultures by over 97%, and the average satisfaction of the audience with the recommended content was over 93%. The application of ethnic cultural knowledge graph in radio and television image dissemination has achieved good results, which can promote the inheritance and innovation of ethnic culture, enhance the cultural connotation and audience satisfaction of radio and television programs.
