Abstract:
Within the service-oriented computing domain, Web service composition is an effective realization to satisfy the rapidly changing requirements of business. Although the research into Web service composition has unfolded broadly, little work has been published towards composition effort estimation. Since examining all of the related work in this area becomes a mission next to impossible, the classification of composition approaches can be used to facilitate multiple research tasks. However, the current attempts to classify Web service composition are not suitable for the research into effort estimation. For example, the contexts and technologies of composition approaches are confused in the existing classifications. This paper firstly proposes an effort-oriented classification matrix for Web service composition, which distinguishes between the context and technology dimension. The context dimension is aimed at analyzing the environmental influence on the effort of Web service composition, while the technology dimension focuses on the technical influence on the effort. Therefore, different context types and technology categories can be treated as different effort factors. Based on the classification matrix, this paper also builds an effort-estimation-checklist table by applying a set of qualitative effort estimation hypotheses to those effort factors. The table can then be used to facilitate comparing the qualitatively estimated effort between different composition approaches.
