An Approach for Composing Services Based on Environment Ontology

Algorithm 3

Decomposition algorithm according to the type of environmental entities.

DecByEntTyp(Req, ReqSet)

(1) if(∃ 𝑒(𝑒∈ Req.Ents∧(type(𝑒) = A∨type(𝑒) = S)))

(2)  ReqSet:= create(𝑒, Req);

(3)  ReqSet:= ReqSet∪DecByDep(Req.Ents-{𝑒});

(4) end if
