- TextdokumentAddressing the Log Representativeness Problem using Species Discovery (Extended Abstract)(EMISA 2024, 2024) Kabierski, Martin; Richter, Markus; Weidlich, MatthiasEvent logs are generated during the enactment of process-centric information systems and form the basis for optimization, monitoring, and enhancement initiatives of said systems. As such, they enable a data-driven and unbiased evaluation of the as-is state of the underlying processes. Yet, since at any time, event logs represent merely a sample of the whole possible behaviour of the information system, insights are only actionable should the event log be representative of the information system from which it is derived. Therefore, the question arises of how the representativeness of an event log$L with respect to its generative system P can be quantified, given that only L is present. In this work, we argue, that representativeness of an event log needs to be assessed with an intended analysis question in mind and discuss log completeness as one important facet of representativeness. We show how established estimators from biodiversity research can be utilized to quantify log completeness.
- ZeitschriftenartikelTechnische Möglichkeiten und Akzeptanz mobiler Anwendungen(Wirtschaftsinformatik: Vol. 47, No. 1, 2005) Hess, Thomas; Figge, Stefan; Hanekop, Heidemarie; Hochstatter, Iris; Rauscher, Barbara; Hogrefe, Dieter; Riedel, André; Zibull, Marco; Kaspar, Christian; Richter, MarkusMobile data communication applications, referred to in this paper as mobile applications, were one of the technological innovation and investment targets in recent years. From the past it became obvious that mono-disciplinary approaches to investigate mobile applications have shortcomings when it comes to successful innovation and investment decisions as interdependencies are insufficiently addressed. The paper therefore aims at structuring the scientific contributions of computer science, business economics and sociology in the context of mobile applications to approximate a holistic understanding comprising technological feasibility, economic opportunities and human needs.
