- KonferenzbeitragAdditional Information in Business Processes: A Pattern-Based Integration of Natural Language Artefacts(Modellierung 2014, 2014) Bittmann, Sebastian; Metzger, Dirk; Fellmann, Michael; Thomas, OliverBusiness process modelling initiatives frequently make use of semi-formal modelling languages for depicting the business processes and their control flows. While these representations are beneficial for the analysis, simulation and automatic execution of processes, they are not necessarily the best option to communicate process knowledge required by employees to execute the process. Hence, textual process representations and their transformation to semi-formal models gain importance. In this paper, a pattern-based modelling approach positioned in between the two extremes of informal text and semi-formal process models is derived. The patterns offer a basis for a seamless integration of natural language and business process models. In particular the business process modelling patterns, which have to rely on human interactions are focussed. For those patterns an integrated representation of information that support the manual execution is developed. The approach fosters the contribution by employees of the operative business, since it does not rely on classical modelling paradigms, but uses natural language for modelling business processes.

- KonferenzbeitragAnalysis of Business Process Model Reuse Literature: Are Research Concepts Empirically Validated?(Modellierung 2014, 2014) Fellmann, Michael; Koschmider, Agnes; Schoknecht, AndreasBusiness process modeling is a highly manual task. The effort of business process modeling might be reduced if process modelers are provided with the option of reusing existing process model assets instead of creating new models from scratch. Numerous research efforts thus have been focused on the reuse of existing model assets leading to a great variety of methods, models, algorithms and tools. However, up to now, the state of empirical evidence in respect to proven positive effects using these approaches is largely unclear. We therefore fill this gap by systematically analysing the available publications. Our paper contributes to the understanding of business process model reuse and consequently also to the knowledge base regarding process model reuse.
- KonferenzbeitragAnalyzing Model Dependencies for Rule-based Regression Test Selection(Modellierung 2014, 2014) Farooq, Qurat-ul-ann; Lehnert, Steffen; Riebisch, MatthiasUnintended side effects during changes of software demand for a precise test case selection to achieve both confidence and minimal effort for testing. Identifying the change related test cases requires an impact analysis across different views, models, and tests. Model-based regression testing aims to provide this analysis earlier in the software development cycle and thus enables an early estimation of test effort. In this paper, we present an approach for model-based regression testing of business processes. Our approach analyzes change types and dependency relations between different models such as Business Process Modeling Notation (BPMN), Unified Modeling Language (UML), and UML Testing Profile (UTP) models. We developed a set of impact rules to forecast the impact of those changes on the test models prior to their implementation. We discuss the implementation of our impact rules inside a prototype tool EMFTrace. The approach has been evaluated in a project for business processes on mobile devices.
- KonferenzbeitragArchitecture of a recommender system to support collaboration in a software environment(WM 2003: Professionelles Wissesmanagement – Erfahrungen und Visionen, Beiträge der 2. Konferenz Professionelles Wissensmanagement, 2003) Lichtnow, Daniel; Loh, Stanley; Saldana Garin, Ramiro; Caringi, Augusto; Anjos, Pablo Lucas dosWithin organizations, people learn through exchanging knowledge. This kind of task (named collaboration) is important for the organizational learning. Collaboration can be supported by Information Technology tools as chats, newsgroups, forums and e-mailing lists. However, this kind of support only enables message exchange, lacking to help people in the learning process. This work presents the architecture of a recommender system to support collaboration among people in an software organization. The system analyzes textual messages sent during the session, identifies the context of the discussion and suggests documents, authorities (people with competence in a subject) and past discussions within the same context.
- KonferenzbeitragAutomated assessment of process modeling exams: basic ideas and prototypical implementation(Modellierung 2016 - Workshopband, 2016) Thaler, Tom; Houy, Constantin; Fettke, Peter; Loos, PeterThe assessment of process modeling exams is a time consuming and complex task. It is desirable to give each student a detailed feedback on their solution in terms of syntactic, semantic, and pragmatic quality. It is obvious that especially in the case of mass courses with hundreds of participants, individual grading of modeling exams by humans is challenging: Besides reliability, consistency, and validity, the efficiency of the grading process must be guaranteed. Against that background, this paper aims at developing first ideas for an automated assessment of process modeling exams. The goal is to improve modeling education while teaching students not only to model correctly but to develop good models. Our ideas were prototypically implemented and applied in an exemplary scenario with promising results. It was possible to identify limitations but also to derive reliable semi-automated approaches for the assessment of process modeling exams.
