The verification technique of complex tasks' nonfunctional specifications in software crowdsourcing

Interest in crowdsourcing is increasing because of its high efficiency and low cost. In the existing platforms of software crowdsourcing, most requesters tend to post decomposed simple subtasks rather than a complex task directly for easier matching workers. However, current platforms of software crowdsourcing can't guarantee the consistency of the complex task and decomposed subtasks. In this paper, we present a solution to automatic verification of the consistency between the whole task's and subtasks' non-functional specifications for software crowdsourcing. An extensible and effective model is proposed to support description and verification of tasks, including their non-functional specifications and structures between subtasks. We also provide process management. Case study on static and dynamic adjustment shows the effectiveness of our solution.
