An embodiment of the invention provides a relation predicating method, a device and
electronic equipment. The relation predicating method comprises the steps of fusing a plurality of medicament single-attribute similarity networks, a plurality of target single-attribute similarity network and a plurality of
disease single-attribute similarity networks, thereby obtaining a fused medicament similarity network, a fused target similarity network and a fused
disease similarity network; constructing a three-element
heterogeneous network according to the fused medicament similarity network, the fusedtarget similarity network and the fused
disease similarity network; predicting the network node of the three-element
heterogeneous network, and obtaining a first association relation which comprisesa first medicament-target association relation, a second medicament-
disease association relation and a first target-
disease association relation. Therefore medicament-target-disease three-element association relation information can be sufficiently mined. The similarity networks of multiple attributes of medicament, disease and target are fused. Accuracy reduction of the predication result causedby eccentricity caused by a single attribute is prevented.
