Precision Score of the heterogeneous similarity metrics (HEEM, HEGM, HVDM, HELM). Precision of the heterogeneous similarity metrics (HSM) measures how many relevant cloud services were ranked and returned by HSM as contained in the gold standard. The gold standard contained the ranking of services produced by HEOM, and it served as the benchmark to measure the precision of the rankings produced by other HSM including HEEM, HEGM, HVDM and HELM. The value of top-k ranged from 5, 10, 15, 20 and 25. HEEM had the highest precision score on all values of k compared to other HSM
