Performance on ovarian cancer data.

WMAXC1 represents the results obtained using only gene expression profile data, whereas the WMAXC2 results were obtained by integrating gene expression profiles and PPI network data. ‘Fold enrichment’ was used to evaluate the performance of the methods and was calculated as , where ‘Selected genes’ is the number of selected genes by the method, ‘Reference genes’ is the number of reference genes from the Ovarian Cancer Dragon Database of genes, ‘Recovered genes’ is recovered genes by the method among the reference genes, and ‘All genes’ represents all genes in the entire network. ‘Recovered interactions’ represents the number of interactions recovered from the PPI network.
