Reusing Service Process Fragments with a Linguistic Approach for User Qualitative Preferences

Prevailing research trend is to use Web services for data publishing and sharing among organizations, but existing works often fall short of service reuse, let alone do they take reusing arbitrary granularities of Service Process Fragments (SPFs) into account. As a matter of fact, SPF reuse can not only improve the efficiency of software development, but also can economize on human and material resources. To reuse SPFs effectively, in this paper, we present an integrated approach, which gets the advantage of the extended Cocke-Kasami-Younger (CKY) algorithm into a marriage of Trade off-enhanced Conditional Preference Network (TCP-net) and the fuzzy linguistic approach. As a result, our method of SPF reuse not only takes the user´s functional requirements into account, but also considers the user´s qualitative preferences over non-functional properties of Web services. Through a set of experiments, the effectiveness and robustness of our approach are evaluated, where the dataset is constructed by the Web Service Challenge Testset Generator¹ (CTG).
