Multi-modal project recommendation method, system and equipment and storage medium

The invention provides a multi-modal project recommendation method, system and device and a storage medium, belongs to the technical field of computers, and realizes personalized project recommendation by constructing a recommendation model based on multi-relation project heterogeneous graph and multi-modal preference fusion. For the multi-relation project heterogeneous graph, on the basis of the graph attention network, obtaining project multi-relation heterogeneous features in different modalities; for the user-item bipartite graph, user modal preference information injected with high-order interaction information in different modal user-item bipartite graphs is captured, attention fusion is carried out on multiple modal preferences of the user, multi-modal preference representation learning of the user is enhanced, and finally the accuracy of a recommendation result is improved. According to the method, the problems of data sparsity and insufficient utilization of the multi-modal information existing in an
