A Cluster and Process Collaboration-Aware Method to Achieve Service Substitution in Cloud Service Processes

Algorithm 2

ServiceVector_Generate (CSCP).

	Input: services and service clusters in CSCP;
Output: vectors for the services and service clusters
(1)	Construct two corpus CP1 and CP2;
(2)	CP1 = CP2 = Φ;
(3)	For each cloud service S in CSCP
(4)	Obtain the sentence send in S.D.Ft and CP1 = CP1 ∪ {Send};
(5)	End for
(6)	For each service net SN in SNP
(7)	ps = PathString_Generate (SN);
(8)	Delete the symbol || and ⊗ from ps
(9)	CP2 = CP2∪{ps};
(10)	End for
(11)	For each cloud service S and service cluster SC in CSCP
(12)	Train word vector S.WOp and S.WTh for the word in S.D.Op and S.D.Th by CP1;
(13)	Train word vector SC.WOp and SC.WTh for the word in SC.D.Op and SC.D.Th by CP1;
(14)	Train service vector PS for S by CP2;
(15)	End for
(16)	Return (S.WOp, S.WTh, SC.WOp, SC.WTh and PS);
