Quality Prediction of Web Services Based on a Covering Algorithm

Algorithm 1

: Clustering users that have invoked web service i.

	Input: and i
	Output: A set of clusters C1, C2, …
	Begin
(1)	cr ⟵ 1;
(2)	identify cD
(3)	do
(4)	identify ccr //(1) when cr = 1 and (3) otherwise
(5)	Cc.center ⟵ ccr
(6)	calculate rcr//(2)
(7)	Ccr.radius ⟵ rcr
(8)	cr ⟵ cr + 1
(9)	while ()
	End
