Davide Fucci and Walid Maalej from MAST, as well as Simone Kühn from the Max Planck Institute for Human Development organized the AffectRE workshop.
The topic of the workshop can be summarized as: As software systems are designed and used by human beings which can be characterized by emotions, the aim of Affective Computing is to study the development of software systems and devices that can recognize, interpret, process, and exploit human affects, feelings, emotion, attitudes and personalities.
The program included Jan Ole Johannsen from the Technische Universität München as the keynote speaker, as well as the presentations of the five accepted papers.
Best Tool and Demo Award
We are proud for receiving the best RE’19 Poster and Tool Demo award for our contribution: Requirements Intelligence with OpenReq Analytics.
The tool is being developed in the Horizon 2020 Project OpenReq. The tool is meant to support requirements engineering related tasks by analyzing user feedback from social media and app stores. Currently, it provides three distinct views – a dashboard that reports the general health of a software product or service, focus views for filtering and reading user feedback, and a competitor comparison. The tool is briefly introduced in the linked video. The linked poster further summarizes the contribution.
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.
This year’s symposium was a huge success and we are very happy to have supported yet another year. If you have interest in the Hamburg Requirements Engineering community (or RE community in general), please reach out to our group to get in touch regarding RE research, industry contacts, the OpenReq project, or anything else you might have in mind.
From the 20-24th of August over 300 researchers met at the beautiful Banff Centre (Alberta, Canada) to present and discuss their latest findings at the 26th International Requirements Engineering Conference (RE’18).
The week was filled with an interesting program. Tutorials, workshops, a doctoral symposium, and an industry day (a sign that the community is making an impact) took place before the three-day main conference.
The main conference (click here for the full program) displayed bleeding-edge research in requirements engineering. Three compelling keynotes—delivered from two world-renowned researchers and a representative of the self-driving car industry—accompanied the sessions. Junior and experienced researchers presented studies, from theoretical to data-driven, in several domains following this year’s theme “Crossing Boundaries and Increasing Impact.” Prof. Walid Maalej was part of the organization and, according to many old-time attendants, RE’18 was one of the most successful in the series.
RE’18 featured also the first edition of AffectRE (co-organized by Davide Fucci), a workshop dedicated to bringing together researchers interested in studying emotions, moods, and affective states to support better requirements engineering practices and tools. The workshop had a good attendance (between 15 and 20 people) and included two invited talks, four research papers, as well as a discussion session to plan the next steps in this emergent community.
The conference (and possibly the AffectRE workshop) will be back next year in Jeju Island (South Korea) for RE’19!

Doctoral Camp 2018!
The MAST Group annual Doctoral Camp was a great success! We took time to reflect on our research, presented our latest results and future PhD plans to our peers, and enjoyed some beautiful Northern-Germany sun. This four-day event provides the opportunity to think through research progress through research presentations given by each PhD researcher, connect with colleagues with shared meals and social events, and relax by absorbing the beautiful weather and landscape. The Doctoral Camp (DocCamp) was held at Fördeferien Bockholmwik, Germany.
The Doctoral Camp presents the MAST PhD researchers the opportunity to communicate their research to the group. Different people are at different stages of their PhD, so the presentations varied. However, a constant among all presentations was the clear progress from last year, and valuable feedback provided by the other MAST members.
Meals and Social Events
The purpose of the DocCamp is more than just a research event, it is also a chance for MAST colleagues to talk about life, hobbies, and anything else that comes to mind. This provides the opportunity to learn about each other beyond the daily work we collaborate on. Every breakfast, lunch, and dinner was prepared by us as a group. We would then go outside and enjoy the meal together, discussing life and whatever else came to mind. Following a nice dinner, it was common to go on a walk through the beautiful landscape, talking about interesting side-projects we were working on, discussing future plans for our lives, and many other things. Between meetings and presentations, we played football and frisbee on the lawn. Additionally, we sat down in the evening to play our favourite board games.
Enjoying the Landscape
The DocCamp was held at Fördeferien Bockholmwik, in North Germany. We had a beautiful view of Denmark, just across the water. The beach, although narrow, provided a nice path to walk on for our nightly walks. Just behind our house was a nice open field, perfect for letting our minds think openly and enjoying outside games together. Thankfully, we were blessed with Sun Sun Sun! We definitely took advantage of the beautiful weather, and are thankful for the accessibility it provided to enjoy the landscape.
Overall, the DocCamp was a success, providing us all with a better understanding of our research, our colleagues, and the general direction of the MAST Group. Looking forward to next year!

On Tuesday, September 19th, Chao REN, a renowned researcher in the field of Sustainable Urban Planning, will visit our group to extensively discuss the state and the general course of the MyKlima project, which deals with the effects of global warming, fast urbanization, and environmental stressors on the quality of life in modern cities.
Additionally, Dr. Benjamin Bechtel
Chao REN is an Associate Professor in School of Architecture, The Chinese University of Hong Kong. Her research interest is Sustainable Urban and Environmental Design and Urban Climatic Application in Urban Planning, focusing primarily on examining the relationship between urban climate and urban morphological characteristics, developing an urban climatic mapping system, and analyzing urbanization-induced human thermal comfort and public health risk impacts for high-density/compact cities.
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.“.
Prof. Walid Maalej is program co-chair of the 26th IEEE International Requirements Engineering Conference (RE’18). Further, the conference chairs include Prof. Daniel Amyot (program co-chair) and Dr. Guenther Ruhe (general chair).
The RE’18 conference will be held from 20 to 24 August 2018 at the world famous Banff center in Alberta, Canada. The conference invites submissions in all areas of RE including elicitation, specification, modeling, analysis, verification, and evolution:
“The conference will offer an extensive program of interest to academia, government and industry.
