Abstract: Provided are a method for determining representation information performed by a computer device. The method includes: obtaining a heterogeneous graph of a target resource service; performing graph convolution on the heterogeneous graph through a graph neural network based on a plurality of types of meta-paths of a plurality of nodes in the heterogeneous graph, to obtain initial representation information of a first-class object node and initial representation information of a second-class object node; and fusing the initial representation information of the first-class object node and the initial representation information of the second-class object node based on an edge connecting different nodes in the heterogeneous graph, to obtain target representation information of the first-class object node.
