中文摘要：

针对已有模型查询机制的查询效率和查准率低下的问题,提出一种以业务单据为中心的业务流程模型相似性查询方法。首先利用聚类技术,综合流程中关键业务单据相似、流程模型结构相似和流程行为相似三个层面对流程模型进行预处理,降低模型查询空间,提高检索效率。在查询过程中,该方法不仅考虑了流程模型的结构和行为,也考虑了流程中的核心业务数据,在保证查全率的前提下进一步提高了查准率。通过实验验证了该方法的有效性。

英文摘要：

Aiming at the low efficiency of existing query mechanism＇s inquiry and precision, an Artifact-centric simi- larity search method for business process models was proposed. By using clustering technology, the process model was pretreated based on key artifacts similarity, structural similarity and behavioral similarity, thus query space was reduced and retrieval efficiency was improved. In the process of query, the precision efficiency was improved further due to not only considered the structure and behavior of process model, but also considered the core data in process. The effectiveness of proposed method was proved by experiment.
