Service-based domain requirements completeness analysis

Service-oriented computing (SOC) is a kind of computing paradigm that utilizes services as fundamental elements for developing applications. In study domain of SOC, modeling and analysis of services-oriented software requirements is an important research direction. Because of frequent changes of individual or collective requirements and continuous evolution of system function & structure, the study object of services-oriented requirement completeness analysis is relative completeness of services requirements but not absolute completeness. This paper focuses emphases on key problem of services-oriented software engineering. First, domain knowledge and software reuse technology are combined to present a framework of services-oriented requirement components modeling; second, constructing and optimizing the requirement components directed graph to automatically realize completeness analysis for service requirements; lastly, the concepts of expected requirements and excited requirements are introduced into our research for quantitatively evaluating the results of completeness analysis. The research platform automatically provide theoretical foundation and tool support for modeling in semantic level and analyzing of services-oriented software requirements, simultaneity it will adapt to the new challenges of software on network environments development mode and improve the agreement degree of stakeholder requirements by a large margin.
