    Improving a Rule-based Fraud Detection System with Classification Based on Association Rule Mining
    (INFORMATIK 2021, 2021) Baumann, Michaela
    Improving a Rule-based Fraud Detection System with Classification Based on Association Rule MiningThe detection of fraudulent insurance claims is a great challenge for insurance companies. Although the detection possibilities are getting better and better, fraudsters do not hesitate also using newer and more sophisticated methods. Apart from establishing new fraud detection systems, also the existing systems need to be updated and improved as best as possible. One common detection system is a rule-based expert system that checks predefined rules and gives alerts when certain conditions are met. Usually, the rules are treated separately and correlations within the rules are considered insufficiently. The work at hand describes how the classification based on association rule mining is used for improving such rule-based systems by bringing in relations between pairs of rules. The rule weights are determined through a genetic optimizer.

    The Process Checklist
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 12, Nr. 1, 2017) Baumann, Michaela; Baumann, Michael Heinrich; Schönig, Stefan; Jablonski, Stefan
    When enterprises are determined to introduce process management, they usually aim at IT system supported execution of processes by Workflow Management Systems (WfMSs) or Process-aware Information Systems. In constrast to this common tendency of process technology, we introduce a paper-based scheme to enact and execute human-driven processes in the work at hand. Our approach is motivated by insights into problems of firms that tried to establish process technology and failed with conventional methods. One of the design objectives for our scheme was to provide a straightforward, quickly viable alternative to WfMS-based process execution at a reasonable effort. The paper-based scheme we introduce follows classical checklist concepts and builds upon the checklist idea in order to reach the same objectives as WfMSs: task coordination, execution guidance, traceability. In this article, we describe how to transform Business Process Model and Notation (BPMN) process models into Process Checklists. We also present extensive evaluations of this approach both in the academic and in the business domain.
