摘要:

过程挖掘正在超越对传统事件日志的挖掘,如今还包括例如来自物联网(IoT)传感器的数据。此类传感器生成的数据量和速度使得传统的集中式事件日志过程发现算法难以高效处理这些数据。本文提出了EdgeMiner,一种直接在传感器节点上对实时事件数据流进行分布式过程挖掘的算法。与集中式算法不同,EdgeMiner在感知和记录事件的传感器节点上直接跟踪每个事件及其前驱和后继事件。由于EdgeMiner在各个节点上聚合直接后继关系,原始数据无需集中存储,从而提高了可扩展性和隐私性。我们通过分析和实验证明了EdgeMiner的正确性。此外,评估结果表明,EdgeMiner能高效确定每个事件的前驱,与查询所有节点相比,通信开销降低了96%。进一步地,我们展示了查询节点数量在相对较少的事件后趋于稳定,并且将前驱查询批量分组,使每个事件平均查询的节点数减少至不到2.5%。

英文摘要:

Process mining is moving beyond mining traditional event logs and nowadays includes, for example, data sourced from sensors in the Internet of Things (IoT). The volume and velocity of data generated by such sensors makes it increasingly challenging to efficiently process the data by traditional process discovery algorithms, which operate on a centralized event log. This paper presents EdgeMiner, an algorithm for distributed process mining operating directly on sensor nodes on a stream of real-time event data. In contrast to centralized algorithms, EdgeMiner tracks each event and its predecessor and successor events directly on the sensor node where the event is sensed and recorded. As EdgeMiner aggregates direct successions on the individual nodes, the raw data does not need to be stored centrally, thus improving both scalability and privacy. We analytically and experimentally show the correctness of EdgeMiner. In addition, our evaluation results show that EdgeMiner determines predecessors for each event efficiently, reducing the communication overhead by up to 96% compared to querying all nodes. Further, we show that the number of queried nodes stabilizes after relatively few events, and batching predecessor queries in groups reduces the average queried nodes per event to less than 2.5%.
