[Lunch Talk] Maximilian König on the Travel Reimbursement Process at HPI

In the first lunch talk of the summer semester, Maximilian talked about his experience from supervising a team elicitating the travel reimbursement process at the HPI in the course of the Trends and Concepts in the Software Industry seminar with Professor Plattner. The goal for the team was to capture the as-is process including travel request and reimbursement, compare it to the best practice process provided by SAP Concur, and finally come up with aspects of the current process that constitute requirements for an adapted best practice process.

[Lunch Talk] Anjo Seidel and Maximilian König on their experience at the ZEUS workshop

Anjo and Maximilian, two new PhD students at the BPT chair, participated in this year’s edition of the Central European Workshop on Services and their Composition (ZEUS) where they both submitted a position paper to outline their future research plans. In their talk, they presented their experiences in Hanover and the other papers presented at the workshop, concerning, for example, semantically equivalent elements in the BPMN standard, and BPMN layout analysis.

[Lunch Talk] Maximilian Völker and Tom Lichtenstein on reference management tools

Reference management tools help researchers in collecting, organizing, and citing the literature they work through. In this session, Maximilian and Tom presented their tool of choice for managing the sources they use for their papers. Maximilian started with an introduction to Citavi, showing his usual workflow with the tool and its browser plug-in which makes the addition of new references as easy as the click of a button. Afterwards, Tom talked about his experience with Zotero, an open source tool available on most platforms. While both provide a similar set of features, getting to know their respective intricacies made this talk very interesting, especially for those not using a reference tool yet.

Prof. Dr. Jan Mendling on "Taming the Complexity of Discovered Process Models"

The plethora of process mining algorithms builds on directly-follows relations. Even though various improvements have been made in the last decade, there are serious weaknesses of these relationships. Once events associated with different objects that relate with a cardinality of 1:N and N:M to each other, these algorithms produce spurious relations, self-loops, and back-jumps. This is due to the fact that the event sequence as described in classical event logs differs from event causation. This talk addresses the research problem of representing the causal structure of process-related event data and presents an approach for causal process mining.

[Lunch Talk] Jonas Cremerius on his experience at the HICSS conference

In the first session of the revived BPT Lunch Talks, Jonas talked about his impressions from the Hawaii International Conference on System Sciences, accompanied by a set of (physical) photos from his visit. The impressions ranged from inspiring research talks to a volcano trip and flightseeing with a helicopter.

Prof. Dr. Matthias Weidlich on "Sampling in Process Mining"

The increasing volume of event data that is recorded by information systems during the execution of business processes creates manifold opportunities for process analytics. At the same time, increasing data volumes impose challenges regarding the scalability of analysis techniques, especially in the context of exploratory analysis. Observing that many insights about a process may be derived from a small share of the event data available in common application scenarios, we provide an overview of our work on sampling in process mining, covering algorithms for process discovery as well as conformance checking.
