The invention discloses a
user participation degree prediction method based on
distillation multi-
modal retrieval enhancement, and belongs to the technical field of
social media data mining and user behavior analysis. According to the method, the correlation of the UGC is evaluated by introducing the self-enhanced
distillation module, and the top-K related UGC is selected in combination with the selected retriever, so that the interference of irrelevant information on the related UGC is effectively avoided, and the
noise caused by irrelevant artifacts can be filtered out when the related UGC is retrieved, thereby keeping the original feature representation of the related UGC. The heterogeneous graph construction module enhances the interactive representation capability between UGCs through multi-relation modeling, and can more accurately optimize a prediction result in
user participation prediction. According to the method,
information retrieval between the related UGC and the unrelated UGC can be better balanced, excessive
diffusion of unrelated information is avoided, and the performance of the model in
user participation degree prediction is improved. Particularly, when complex multi-
modal data containing a large number of irrelevant UGCs is processed, the mechanism can effectively enhance the distinction degree of the relevant UGCs, and the prediction accuracy is improved.
