Abstract: Highlights•We formally propose a metapath-guided trust prediction approach.•Category-aware metapaths are constructed while preserving the original structure.•To preserve the heterogeneity of HSN structure, multiple metapaths are fused.•This is the first interaction-based metapath-guided trust prediction model.
