In collaboration with HITeC, OpenReq and Iteratec, we organized the 2nd Hamburg Requirements Engineering Symposium on September 4th, 2019. This event gathered 65 participants from industry and academia to discuss the state-of-the-art in RE, particularly applying Machine Learning and Artificial Intelligence to Requirements Engineering and vice versa. The event consisted of two keynote speakers, 14 talks in two parallel tracks, and Demos/Posters as well as networking opportunities through the coffee and lunch break. With such a high turnout (twice as many people as last year) and positive responses from the participants, this event was a large success.
The first keynote was by Dr. Prof. Vogelsang from TU Berlin, titled: “Is AI changing RE or is RE changing AI?” started the event off strong. Vogelsang gave the audience a big picture perspective on AI and RE, and how the two fields are interacting with and changing each other. Following Vogelsang, Dr. Stettinger from TU Graz gave a presentation of OpenReq Live, the main tool output of the OpenReq project. To close the event, Prof. Dr. Mobasher from DePaul University in the US gave an in depth keynote on the current trend of Context-Aware Recommender Systems.
The talks at this year’s symposium included talks from OpenReq members, OpenReq OpenCall partners, and members from the RE industry. Besides the keynotes, there were four sessions at this year’s symposium. The topics of the sessions were: User Feedback, Requirements & Developers, RE in Practice: Specs and Beyond, and Machine Learning for Issue Trackers.
User Feedback provided insights into how RE can leverage the magnitude of end-user feedback that currently exists regarding software (and hardware) products. Requirements & Developers discussed how to connect developers with requirements, whether that be through supporting and enhancing their workflow, or building better requirements documents to make their job easier. RE in Practice: Specs and Beyond gave a refreshing perspective on how RE is conducted in practice, current challenges, and how state-of-the-art research is being used to enhance the workflow of requirements engineers. And finally, Machine Learning for Issue Trackers took a look at industry standard issue trackers to manage requirements, and how innovative work within OpenReq is improving how developers and requirements engineers interact with them.
Following the main event, there was a 90 minutes boat trip through the Hamburg harbor. The weather held out long enough for the participants to have a thorough history lesson while enjoying the beautiful views offered by the Elbe river and Hamburg harbor.
Finally, the 2nd Hamburg Requirements Engineering Symposium came to a close with the participants connecting over good food and a relaxed atmosphere.
One of the most vibrant topics in requirements engineering research is the analysis of app reviews. The field is concerned with helping developers and managers to extract information from masses of unstructured and freely-written user reviews. The goal is to better understand user needs such as problems users face and features they wish would be integrated in the app. The Data Challenge was taking place on Monday and Tuesday of the OpenReq Week. We distributed six thousand app reviews labeled as problem report, feature request, and other. The participants were also given ten thousand English tweets containing the same labels, as well as issue tracker data to come up with ideas on how to perform an accurate classification. The winner of the Data Challenge, Tim Pietz, a computer-science student at the University of Hamburg, applied Google’s state-of-the-art deep learning model BERT to perform the classification task. He successfully outperformed approaches from research by up to 7% (f1 score).
The Eclipse Hackathon, in parallel with the Data Challenge, took place on Tuesday of the OpenReq Week. The objective of this Hackathon was to improve the Eclipse IDE with the help of OpenReq. Participants were asked to use the OpenReq Eclipse IDE Bug prioritizer plugin to find bugs to resolve. The plugin shows bug reports and feature requests from bugs.eclipse.org based on a personalized recommendations for the current user. It further shows the most discussed bugs in the last 30 days from bugs.eclipse.org to find bugs with a potentially high impact. The hackathon winner will be announced in a few weeks after we had been able to evaluation all contributions.

Hamburg’s State Minister of Science, Research and Equality Katharina Fegebank presented together with Prof. Maalej and Daniel Martens from our research department the new science app “Metropole des Wissens” at the State Press conference. The app is dedicated to all citizens interested in science. The aim of the app is to stronger connect science within the city state of Hamburg and the interested public.
The app is a success story for knowledge and technology transfer at the University of Hamburg. The initial version of the app was developed with the lighthouse-teaching project M-Lab. Within this course students develop innovative mobile apps by using the latest technology. At the beginning of the three-month course practice partners from industry, public sector, and civil institutions present the students their problem statements. The ministry for science, research and equality took part in the M-Lab course in 2015. A team of four students (Minka Halilovic, Javad Malaquti, Paul Mazgajski, and Daniel Martens) developed the initial version of the app, which aggregates content, such as news and events, of the scientific institutions within Hamburg. At the end of the project the students presented the app to the first and second major of the city of Hamburg within the town hall.
The app and its concept received great enthusiasm. It was further developed and tested, and is from now on available for free within the Apple AppStore. Katharina Fegebank, Hamburg’s State Minister of Science, Research and Equality: „With this app… citizen can dive in digitally with one click from anywhere in the Hamburg’s science“
Prof. Maalej concludes: “the students designed the app for the future and other institutions can easily integrate their content into the app — even Germany- wide” .

Heute stellten die Wissenschaftssenatorin Katharina Fegebank gemeinsam mit Prof. Dr. Walid Maalej und Daniel Martens von unserem Arbeitsbereich die neue Wissenschafts-App „Metropole des Wissens“ auf der Landespressekonferenz vor. Die App richtet sich alle an der Wissenschaft interessierten Bürgerinnen und Bürger. Ziel ist es, die Wissenschaft in Hamburg noch stärker miteinander und mit der interessierten Öffentlichkeit zu verknüpfen.
Die App ist ein Erfolgsbeispiel für den Wissens- und Technologietransfer an der Universität Hamburg. Sie ist ursprünglich aus dem Lehr- und Innovationsprojekt M-Lab hervorgegangen, in dem Studierende unter Verwendung neuester Technologien innovative Smartphone-Apps entwickeln. Zu Beginn des dreimonatigen Projekt präsentieren die Praxispartner aus Wirtschaft, öffentlicher Hand und zivilgesellschaftliche Institutionen den Studierenden ihre Problemstellung. Auch die Behörde für Wissenschaft, Forschung und Gleichstellung nahm an M-Lab teil. Ein vierköpfiges Studententeam (Minka Halilovic, Javad Malaquti, Paul Mazgajski, und Daniel Martens) entwickelte dort die initiale „Metropole des Wissens“ App. Diese aggregiert die Inhalte, z.B. Neuigkeiten und Veranstaltungen, der wissenschaftlichen Institutionen Hamburgs. Im Anschluss an das Projekt haben die Studierenden dem 1. Bürgermeister und der 2. Bürgermeisterin die App im Rathaus präsentiert.
Die App und dessen Konzept stießen auf große Begeisterung. Sie wurde weiterentwickelt und getestet und ist ab sofort im Apple AppStore kostenfrei verfügbar ist. Katharina Fegebank, Senatorin für Wissenschaft, Forschung und Gleichstellung: „Mit der heute vorgestellten App tragen wir die Wissenschaft noch stärker in die Stadt und informieren Bürgerinnen und Bürger noch besser darüber, was es alles in den wissenschaftlichen Institutionen Hamburgs zu entdecken gibt. Damit kann man jetzt auch digital von überall mit einem Klick in die Wissenschaft der Stadt eintauchen. Der digitale Wandel erfasst nahezu alle Lebensbereiche. Wir gestalten diesen Wandel, nutzen seine Chancen und stärken die Schlüssel-Disziplin der Digitalisierung: die Informatik.“
Prof. Dr. Walid Maalej fügt abschließend hinzu: „Wir haben aus technischer Sicht alle Vorbereitungen getroffen um Inhalte weiterer außeruniversitärer Forschungsinstitutionen in die App zu integrieren. Dazu haben wir die neuesten Technologien verwendet. Ich würde mich sehr freuen in Kürze weitere Inhalte der Hamburger Wissenslandschaft integriert zu sehen – und in Zukunft im besten Fall auch bundesweite Inhalte.“.
