@inproceedings{matthies2019BotSE, abstract = {With the recent advances in natural-language processing, combined with the ability to analyze large amounts of data across various domains, software bots can become virtual team members, providing an additional set of automated eyes and additional perspectives for informing and supporting teamwork. In this paper, we propose employing chatbots in the domain of software development with a focus on supporting analyses and measurements of teams' project data. The software project artifacts produced by agile teams during regular development activities, e.g. commits in a version control system, represent detailed information on how a team works and collaborates. Analyses of this data are especially relevant for agile retrospective meetings, where adaptations and improvements to the executed development process are discussed. Development teams can use these measurements to track the progress of identified improvement actions over development iterations. Chatbots provide a convenient user interface for interacting with the outcomes of retrospectives and the associated measurements in a chat-based channel that is already being employed by team members.}, author = {Matthies, Christoph and Dobrigkeit, Franziska and Hesse, Guenter}, booktitle = {1st International Workshop on Bots in Software Engineering (BotSE)}, keywords = {software_engineering}, note = {(accepted)}, title = {An Additional Set of (Automated) Eyes: Chatbots for Agile Retrospectives}, year = 2019 }

@inproceedings{matthies2018fie, abstract = {This Innovative Practice Full Paper presents an approach of using software development artifacts to gauge student behavior and the effectiveness of changes to curriculum design. There is an ongoing need to adapt university courses to changing requirements and shifts in industry. As an educator it is therefore vital to have access to methods, with which to ascertain the effects of curriculum design changes. In this paper, we present our approach of analyzing software repositories in order to gauge student behavior during project work. We evaluate this approach in a case study of a university undergraduate software development course teaching agile development methodologies. Surveys revealed positive attitudes towards the course and the change of employed development methodology from Scrum to Kanban. However, surveys were not usable to ascertain the degree to which students had adapted their workflows and whether they had done so in accordance with course goals. Therefore, we analyzed students' software repository data, which represents information that can be collected by educators to reveal insights into learning successes and detailed student behavior. We analyze the software repositories created during the last five courses, and evaluate differences in workflows between Kanban and Scrum usage.}, author = {Matthies, Christoph and Teusner, Ralf and Hesse, Guenter}, booktitle = {2018 IEEE Frontiers in Education Conference (FIE)}, keywords = {development_artifacts software_engineering Kanban Scrum Education}, month = {oct}, pages = {1-9}, publisher = {IEEE}, title = {Beyond Surveys: Analyzing Software Development Artifacts to Assess Teaching Efforts}, year = 2018 }

@inproceedings{Guenter2017a, abstract = {Against the backdrop of ever-growing data volumes and trends like the Internet of Things (IoT) or Industry 4.0, Data Stream Processing Systems (DSPSs) or data stream processing architectures in general receive a greater interest. Continuously analyzing streams of data allows immediate responses to environmental changes. A challenging task in that context is assessing and comparing data stream processing architectures in order to identify the most suitable one for certain settings. The present paper provides an overview about performance benchmarks that can be used for analyzing data stream processing applications. By describing shortcomings of these benchmarks, the need for a new application benchmark in this area, especially for a benchmark covering enterprise architectures, is highlighted. A key role in such an enterprise context is the combination of streaming data and business data, which is barely covered in current data stream processing benchmarks. Furthermore, first ideas towards the development of a solution, i.e., a new application benchmark that is able to fill the existing gap, are depicted.}, address = {New York, NY, USA}, author = {Hesse, Guenter and Matthies, Christoph and Reissaus, Benjamin and Uflacker, Matthias}, booktitle = {Proceedings of the 11th ACM International Conference on Distributed and Event-based Systems}, keywords = {Internet_of_Things Performance_Benchmarking Stream_Processing Benchmark_Development Data_Stream_Processing}, pages = {359-362}, publisher = {ACM}, series = {DEBS '17}, title = {A New Application Benchmark for Data Stream Processing Architectures in an Enterprise Context: Doctoral Symposium}, year = 2017 }
