Madhavi Bangalore Shankara Narayana, Hossameldin Khalifa, Wil van der, Aalst

TL;DR
This paper introduces JXES, a JSON-based standard for process mining event logs compatible with XES, along with implementations and performance evaluations of different JSON parsers.
Contribution
It presents the JXES standard for JSON event logs and provides ProM implementations for importing and exporting, addressing performance considerations.
Findings
Performance varies significantly across different JSON parsers.
JXES enables seamless integration of JSON logs with existing process mining tools.
Implementation supports four different JSON parsers for flexible use.
Abstract
Process mining assumes the existence of an event log where each event refers to a case, an activity, and a point in time. XES is an XML based IEEE approved standard format for event logs supported by most of the process mining tools. JSON (JavaScript Object Notation) is a lightweight data interchange format. In this paper, we present JXES, the JSON standard for the event logs and also provide implementation in ProM for importing and exporting event logs in JSON format using 4 different parsers. The evaluation results show notable performance differences between the different parsers (Simple JSON, Jackson, GSON, Jsoninter).
