Construction of the embedding matrix of $l_2$-$d_4$ pair. (a) Construction of the first part of the embedding matrix based on the similarity between $l_2$ and the other lncRNAs and the association between $d_4$ and all lncRNAs. (b) The second part of the embedding matrix was constructed based on the similarity between $l_2$ and the other lncRNA and the association between $d_4$ and the other diseases. (c) Construction of the third part using the lncRNA-miRNA interactions and miRNA-disease associations. (d) Construction of the final embedding matrix ${\mathit{P}}_{\mathbf{2},\mathbf{4}}$ by combining the representations of the first, second, and third parts.
