摘　　要：为了在计算流程模型相似度时考虑到业务流程数据,解决以Artifact为中心的业务流程模型相似性度量问题,分析了业务流程执行过程中对数据的操作,提出了一种面向以Artifact为中心的业务流程相似度计算方法。对以Artifact为中心的流程模型的定义进行了扩展,增加了数据属性操作的描述;抽取Artifact数据属性的操作序列,将业务流程模型分解为Artifact数据属性操作序列集合;对数据属性操作序列进行分类,计算不同业务流程模型间数据属性操作序列相似度,进而得到以Artifact为中心的业务流程模型间的相似度。实验结果表明,该方法不仅体现了业务流程模型的数据操作特性,也体现了业务流程模型的行为,为以Artifact为中心的流程模型相似度计算提供了一种可行的方法。To consider the business process data when computing process model similarity,and to solve Artifact-centric business processes similarity measuring,a novel Artifact-centric business processes similarity measuring method was proposed by analyzing executive process of business process.The definition of Artifact-centric business process model was expanded to increase the description of data operation.The operation sequence of data items based on Artifact-centric business process was extracted.Data operation sequence was classified,and the similarity of different operation sequence was calculated.Thus,the similarity of all classes of data items was aggregated to measure the similarity between Artifact-centric business processes.The results showed that the proposed method was not only more consistent with the properties of process behavior similarity algorithm than the existing algorithm,but also a good similarity measuring for data-centric business process.
