AI总结:

本文针对对象中心化过程挖掘中现有事件日志格式在流式数据场景下灵活性、可扩展性和可维护性不足的问题,提出了一种基于中心辐射型架构的中间数据存储枢纽数据库格式及新型关系模式,并通过轻量级开源数据栈实现端到端方案加以验证。

摘要:

对象中心化过程挖掘正在成为跨行业的一种有前景的范式,吸引了大量学术关注。为了支持其数据需求,现有的对象中心化数据格式主要用于促进数据所有者、研究人员和分析师之间静态事件日志的交换,而不是作为持续数据摄取和转换管道的稳健基础数据模型,以支持后续的存储和分析。这种侧重导致了在灵活性、可扩展性和可维护性方面的次优设计选择。例如,当前的对象中心化事件日志格式难以处理流式数据中出现的新对象类型或新属性。本文提出了一种为中间数据存储枢纽设计的数据库格式,该格式采用中心辐射型架构将过程挖掘应用与其数据源分离。本文从数据工程角度阐述了稳健的对象中心化事件日志存储的基本需求,并引入了一种针对这些需求定制的新型关系模式。为了验证所提出的数据库格式的有效性,使用轻量级开源数据栈实现了一个端到端解决方案。我们的实现包括用于各种对象中心化事件日志格式的数据提取器、自动化数据质量评估以及直观的过程数据可视化能力。

英文摘要:

Object-centric process mining is emerging as a promising paradigm across diverse industries, drawing substantial academic attention. To support its data requirements, existing object-centric data formats primarily facilitate the exchange of static event logs between data owners, researchers, and analysts, rather than serving as a robust foundational data model for continuous data ingestion and transformation pipelines for subsequent storage and analysis. This focus results into suboptimal design choices in terms of flexibility, scalability, and maintainability. For example, it is difficult for current object-centric event log formats to deal with novel object types or new attributes in case of streaming data. This paper proposes a database format designed for an intermediate data storage hub, which segregates process mining applications from their data sources using a hub-and-spoke architecture. It delineates essential requirements for robust object-centric event log storage from a data engineering perspective and introduces a novel relational schema tailored to these requirements. To validate the efficacy of the proposed database format, an end-to-end solution is implemented using a lightweight, open-source data stack. Our implementation includes data extractors for various object-centric event log formats, automated data quality assessments, and intuitive process data visualization capabilities.
