摘　　要：物联网贯穿于人们生活中的众多领域,随着其快速的发展和业务需求的不断变化,在处理持续到达的流数据时,由专业人员构事先构建业务流程的传统方法已经无法满足用户需求,而由最终用户直接构建以控制流为中心的服务组合流程时,往往需要用户对其细节进行精确的定义,使不具备专业知识的用户难以理解和操作,从而无法完成构建。针对构建物联网服务组合流程所存在的问题,提出了一种面向数据的用户可直接对数据视图进行操作的流程构造方法,提供了可视化的数据视图操作及操作对应的转换规则,支持最终用户直接对数据视图进行操作从而构建流服务组合流程。通过实验案例和相关工作的分析比较,表明该方法可降低最终用户构造流程的复杂性并提高建模的效率。The Internet of Things runs through many areas of people’s lives.With its rapid development and continuous changes in business needs,the traditional method of professionally constructing business processes in advance when processing continuously arriving streaming data has been unable to meet user needs.When an end user directly builds a control flow-centric service composition process,the user often needs to define its details accurately,making it difficult for users without professional knowledge to understand and operate,and thus unable to complete the construction.Aiming at the problems existing in the construction of the IoT service composition process,we propose a process construction method for data-oriented users to directly operate on data views and provide visual data view operations and corresponding conversion rules for operations to support end users,which manipulates data views directly to build a stream service composition process.The analysis and comparison of experimental cases and related work show that the proposed method can reduce the complexity of the end-user construction process and improve the efficiency of modeling.
