Abstract: To realize effective construction of different roles, a role identification method was brought forward based on techniques of workflow logs mining and process decomposition. Role identification was analyzed from several layers, and carried out from bottom to top through workflow logs mining. Moreover, a role tree was designed according to business processes. In this method, relevancy parameter was used to define the role granularity so as to form the leaf roles. Then, the concept of process manager was introduced to identify the topper roles and define hierarchical division of roles. Finally, the fruit of workflow model mining was borrowed to depict the activity dependences of relevant roles, meanwhile to complete interactive roles identification.

Key words: role, workflow logs mining, identification

摘要： 为实现角色的有效识别，提出了一种将工作流日志挖掘与流程分解相结合的角色识别方法，充分挖掘工作流日志，从多个层面分析问题,自下而上逐层提取，生成一棵与业务流程相对应的角色树。在该方法中，通过挖掘工作流日志，用关联参数规范角色粒度，形成叶子角色。引入流程经理概念，实现基于流程分解的内部角色识别，解决角色的层次性划分问题；沿用工作流模型挖掘的成果，对角色间的活动依赖进行了刻画，由此完成了角色交互行为识别。
