sentence: In this section , we construct four tetramerous heterogeneous networks ( THN1 , THN2 , THN3 , and THN4 ) , six tripartite heterogeneous networks ( TriHN1 , TriHN2 , TriHN3 , TriHN4 , TriHN5 , and TriHN6 ) , and four duplex heterogeneous networks ( DHN1 , DHN2 , DHN3 , and DHN4 ) on LncRNADisease based on the disease semantic similarity , the lncRNA function similarity , the lncRNA Gaussian profile kernel similarity , the disease Gaussian profile kernel similarity , and the known disease-lncRNA interaction for comparison .
