Abstract &   Background	Abstract Business Service, as an abstraction of concrete realization of a business activity, helps to relieve the complexity in end-user-oriented service assembly and reuse. However, there lacks a standard instantiation method for realizing business services on top of concrete software services. The paper proposes an instantiation method for business services on the basis of the generalization-specification patterns. By examining and summarizing generalization-specification relations and the patterns thereof, the customized business services that are adapted to end-user requirements only need to match to the software services that fall into the category of the patterns. Experiments indicate that the instantiation method can help to reduce the matching redundancy and to improve the instantiation efficiency. Keywords business service; generalization-specification patterns; instantiation; adjacent upper bound Background This paper is primarily supported by the National Natural Science Foundation of China under grant No.60573117, which explores end-user-doable service composition. The paper proposes an instantiation method for business services on the basis of the generalization-specification patterns. Experiments indicate that the instantiation method can help to reduce the matching redundancy and to improve the instantiation efficiency. Compared with the existing work, the research results presented in this paper can make a business service match to the software services accurately and faster.
