摘要:

预测业务流程实例执行期间的不良事件为流程参与者提供了一个干预并保持流程与其目标一致的机会。很少有解决这一挑战的方法考虑多视角视图,其中流程的流程视角与其周围的环境相结合。鉴于当今世界的数据来源众多,上下文可能差异很大,并具有各种含义。本文讨论的问题,上下文是下一个事件的原因或结果,它对下一个事件预测的影响。我们利用以前的工作概率模型,开发一个动态贝叶斯网络技术。概率模型被认为是可理解的,它们允许最终用户及其对预测领域的理解。我们的技术模型的上下文属性,要么有一个原因或影响关系的事件。我们评估我们的技术与两个现实生活中的数据集和基准它与其他技术从预测过程监测领域。结果表明,如果上下文信息被正确地引入到模型中,我们的解决方案实现了优越的预测结果。

英文摘要:

Predicting undesirable events during the execution of a business process instance provides the process participants with an opportunity to intervene and keep the process aligned with its goals. Few approaches for tackling this challenge consider a multi-perspective view, where the flow perspective of the process is combined with its surrounding context. Given the many sources of data in today's world, context can vary widely and have various meanings. This paper addresses the issue of context being cause or effect of the next event and its impact on next event prediction. We leverage previous work on probabilistic models to develop a Dynamic Bayesian Network technique. Probabilistic models are considered comprehensible and they allow the end-user and his or her understanding of the domain to be involved in the prediction. Our technique models context attributes that have either a cause or effect relationship towards the event. We evaluate our technique with two real-life data sets and benchmark it with other techniques from the field of predictive process monitoring. The results show that our solution achieves superior prediction results if context information is correctly introduced into the model.
