where N is the number of services, C
is the number of Star Technology Project
Centers concordant pairs between two lists, D Star
Technology Projects Center
is the number of discordant pairs, and there are totally Star
Technology Project Center
pairs for N cloud services. Since Star Technologies
Projects Centers is equal to Star
Technologies Project Centers
. Employing KRCC, the similarity between two service rankings can
be calculated by Star Technologies Projects
Center is the subset of cloud services commonly
invoked by users u and v, qu;i is the QoS value Star
Technologies Project Center
response time, throughput, etc. of service i observed by user u,
and IðxÞ is an indicator function defined as Star Center
Madurai otherwise: From above definition, the
ranking similarity between two rankings is in the interval of Star
Technologies Student is obtained
when the order of user u is the exact reverse of user v, and 1 is
obtained when order of user u is equal to the order of user v.
