The heterogeneous information network. Two types of weighted meta-graphs (i.e. Fig. 6b,d) can be utilized to obtain the probability score of interaction between new disease node d₃ and candidate microbe node m₄, such as weighted meta-graphs consisting of d₃,d₄,m₄ and d₃,d₂,m₂,m₄, respectively. d₃ represents unlabeled disease; d₁,d₂,d₄ and d₅ denote labeled disease; m₁,m₂,m₃,m₄,m₅ and m₆ represent labeled microbes; Solid lines and dotted line in the bipartite network means known and unknown bipartite linkings, respectively
