Workshop Organization

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.

2nd Hamburg RE Symposium – a Recap

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.

Data Challenge

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).

Eclipse Hackathon

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.

Final Thoughts

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.

The SEmotion workshop will take place for the fourth time at ICSE 2019

The SEmotion workshop focuses on topics at the intersection of affective computing and software engineering.

Affective states such as personality traits, attitudes, moods, and emotions play a crucial role for developers performance as well as for the success of their product. For example, several software engineering tasks include acceptance and negotiation activities in which emotions play a crucial role—e.g., discussion about issues found on GitHub, or request for help on StackOverflow.

SEmotion is now at its fourth edition and has created an international community for researchers and practitioners in the area to present and discuss their work in progress regarding empirical studies, theoretical models, and tools to support affective computing in software engineering.

As for the previous three editions, SEmotion will be co-located with ICSE, a premier conference for software engineering research, in Montreal, Canada. This edition will be co organized by Davide Fucci from MAST, together with Bonita Sharif from the University of Nebraska in USA, and Giuseppe DeStefanis from Brunel Univesity in UK.

The SEmotion workshop series started in 2016 when ICSE took place in Austin, Texas and was co-organized by prof. Walid Maalej. Since then, researchers from MAST have contributed to the workshop programme and presented their work to this community.

MAST @ Tag des Wissens

Daniel Martens, Marlo Häring, and Christoph Stanik represented MAST, Forum 4.0, OpenDataStudio, and OpenReq at the Tag des Wissens—a public event at which researchers present and discuss their work with interested citizens. Under the theme “Technik und Digitale Welten” (Technology and Digital Worlds), the event took place on September 22nd at the Hamburg University of Technology TUHH. With about 4,500 visitors, the Tag des Wissens generated a lot of interest and a campus full of curious and knowledge seeking citizens. MAST held one presentation and data analytics and one interactive workshop for kids.

 

 

Talk – Data Analytics

The talk was about “Data Analytics” covering the basics of this field and its application in our research areas App Stores and Online Journalism. Besides an introduction to data analytics, machine learning, and big data, we showed and motivated the need for and the value within publicly available user comments. In our research, we automatically analyze user comments to e.g., identify bug reports and feature requests in app stores to first, give people a chance to be heard and second, to give app developers a chance to understand their users’ needs—a task difficult to do manually, as popular apps receive thousands of user comments each day. In the EU project OpenReq, this is one of the topics we address. In our analysis of user comments in news articles, which is part of the project Forum 4.0, we aim to systematically analyze, aggregate and visualize the content and quality of comments at runtime in order to enable constructive participation. Forum 4.0 combines research from social science and computer science.

Interactive Workshop – M-Lab Junior

Further, we had one interactive workshop with kids. In groups of six, the kids had to design a mobile app using pen and paper. The problem statement was: Imagine you go for a walk with your parents. You may find a leaf on the ground you have never seen before, how do you know to which tree it belongs to? Therefore, the goal was to design an innovative app to identify the tree the leaf belongs to but also to give further information on the tree.

Doctoral Camp 2018

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.


Research Presentations

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!

MAST-Team won 10,000 Euro at the national “Hochschulwettbewerb”

The MAST team is proud to announce that its contribution “OpenDataStudio” is one of the awarded projects of the national competition “Hochschulwettbewerb” 2018 with the theme “Future Working World” in which universities from all over Germany competed with each other.

With “OpenDataStudio” Yen Dieu Pham, Christoph Stanik and Prof. Dr. Walid Maalej are inviting researchers, citizens, and public authorities to critically discuss and learn about risks, challenges and chances of open data especially provided by cities.
Open data is accessible for everyone, but many do not know the chances and consequences. Therefore, it is important to create an understanding of how such data is generated. This understanding is an essential part of the OpenDataStudio as well as learning how data can be used to improve, e.g., the quality and flow of the everyday life.

With the reward of 10,000 Euro “OpenDataStudio” will develop a concept to explain OpenData to non-technical people as well as to create ideas and prototypes with the participants based on OpenData. The participants will learn how to deal with OpenData and how to generate it. At the end of the project, the teams will present their experiences, ideas and the prototypes at a public event. Supporters and interested people are welcome to join us, starting from now on.
