Integration of molecular network data reconstructs Gene Ontology.
Bottom Line: Furthermore, we use our method to infer new relationships between GO terms solely from the topologies of these networks and validate 44% of our predictions in the literature.In addition, our integration method reproduces 48% of cellular component, 41% of molecular function and 41% of biological process GO terms, outperforming the previous method in the former two domains of GO.Finally, we predict new GO annotations of yeast genes and validate our predictions through GIs profiling.

Mentions: We compute the percentage of reproduced, high confidence GO terms for CC, BP and MF separately. The results are shown in Figure 3a. Better results are achieved when GDV similarity matrices are included in the prediction model. Specifically, we capture 41% of BP terms, 41% of MF terms and 48% of CC terms. The BP and MF results outperform those of Dutkowski et al. (2013), whereas they achieve a higher percentage of reproduced GO terms in CC.Fig. 3.
