Title of talk:
The Challenges of Affect Detection in the Social Programmer Ecosystem
Date and Time:A�Monday, 25th January 2016 at 17:15A�PM
Place:A�Informatikum, Room D-125 Vogt-KA�lln-Str. 30, 22527 Hamburg
Software engineering involves a large amount of social interaction, as programmers often need to cooperate with others, whether directly or indirectly. However, we have become fully aware of the importance of social aspects in software engineering activities only over the last decade. In fact, it was not until the recent diffusion and massive adoption of social media that we could witness the rise of the a�?social programmera�? and the surrounding ecosystem. Social media has deeply influenced the design of software development-oriented tools such as GitHub (i.e., a social coding site) and Stack Overflow (i.e., a community-based question answering site). Stack Overflow, in particular, is an example of an online community where social programmers do networking by reading and answering othersa�� questions, thus participating in the creation and diffusion of crowdsourced knowledge and software documentation.
One of the biggest drawbacks of computer-mediated communication is to appropriately convey sentiment through text. While display rules for emotions exist and are widely accepted for interaction in traditional face-to-face communication, web users are not necessarily prepared for effectively dealing with the social media barriers to non-verbal communication. Thus, the design of systems and mechanisms for the development of emotional awareness between communicators is an important technical and social challenge for research related to computer-supported collaboration and social computing.
As a consequence, a recent research trend has emerged to study the role of affect in the social programmer ecosystem, by applying sentiment analysis to the content available in sites such as GitHub and Stack Overflow, as well as in other asynchronous communication artifacts such as comments in issue tracking systems. This talk surveys the state-of-the-art in sentiment analysis tools and examines to what extent they are able to detect affective expressions in communication traces left by software developers. A discussion is offered about the advantages and limitations of choosing sentiment polarity and strength as an appropriate way to operationalize affective states in empirical studies. Finally, open challenges and opportunities of affective software engineering are discussed, with special focus on the need to combine cognitive emotion modeling with affective computing and natural language processing techniques to build large-scale, robust approaches for sentiment detection in software engineering.

On May 15th. 2014A�the State Premier & First Mayor of Hamburg Olaf Scholz visited the Department of Informatics at the University of Hamburg. Our group MOBIS was honored to be among the research groups, which were selected to present their work to him and the accompanying team of high-ranking officers and decision makers. We presented a A�part of our european research project MUSESA�and our approach to deal with the challenges of theA�Bring Your Own Device (BYOD) trend. Our poster (in German) can be downloaded from this link.A�It shows our solution to distinguish automatically between private and professional usage of mobile devices by using machine learning techniques. The main application scenarios include the automatic reporting of extra working hours, the protection of users’ privacy when using corporate devices and the protection of company’s assets when using private devices. Scholz was highly interested in this topic and discussed with us possible use cases and legal implication.
At the end of the visit, the head of MOBIS Prof. Maalej handed over a voucher to Scholz which consists of gift toA�the State City of Hamburg for the development of an App as part of our lighthouse M-Lab projects.

A�Zusammenfassung: MA�dchen ab der 9 Schulklasse kA�nnen Informatik spielerisch kennenlernen mit Angry Birds und der Elbphilharmonie!
Wir sind der Arbeitsbereich fA?r Apps und Software Entwicklung und wollen Euch in 3 Stunden die tolle Welt der Informatik spielerisch vorstellen.
Wollt Ihr schon immer Wissen was Informatik ist? Wer hat Informatik, die Computer und alles was mit Facebook und Google zu tun hat eigentlich erfunden? War es ein Hamburger, hier an der UniversitA�t Hamburg? Zu all diesen Fragen und werden wir Euch imA�ersten TeilA�unserer Veranstaltung Antworten geben.
Wollt Ihr schon immer mal Eure eigenes Computerprogramm schreiben und dachtet Ihr: Das ist doch zu kompliziert? Wir werden Euch imA�zweiten TeilA�dieser Veranstaltung das Gegenteil zeigen! Innerhalb von nur einer Stunde werden wir den bA�sen Schweinchen aus Angry Birds mit unseren Programmierwerkzeugen zeigen, dass wir uns nicht A�rgern lassen. Jedes Team versucht dabei durch kleine Programmbausteine das Angry Bird durch ein Labyrinth zu fA?hren, um das grA?ne Schweinchen zu vertreiben.
Und das ist noch nicht alles! Nachdem wir den Schweinchen gezeigt haben, wer der Chef ist, wartet eine neue Herausforderung auf uns: Hungrige Zombies. Bevor Sie uns fressen, mA?ssen wir Ihnen Schritt fA?r Schritt mehr Pflanzen zum Essen geben. Vielleicht schaffen wir es, Sie zu A?berzeugen, dass Pflanzen doch das bessere Hauptgericht sind.
Nun, Informatik ist viel mehr als Programmieren! Wie in der realen Welt, brauchen Informatiker auch Architekten, damit komplizierte Programme, was in der realen Welt mit einem Haus, vielleicht auch der Elbphilharmonie vergleichbar ist, nicht in sich zusammenbrechen. Wusstet Ihr das?
ImA�dritten TeilA�unserer Veranstaltung dA?rft Ihr Softwarearchitekten sein und lernt die andere Seiten kennen, mit der sich Informatiker, fernab des Programmierens tagtA�glich beschA�ftigen mA?ssen, damit am Ende ein windfestes, krisensicheres und zuverlA�ssiges Programm entsteht, und das tut was man von dem erwartet.
A?berzeugt das Euch alles nicht? Denkt Ihr noch: Informatik ist doch nichts fA?r mich! Da sind doch nur doofe Jungs! DenA�letzten TeilA�unserer Veranstaltung werdet Ihr mit Informatikerinnen verbringen, die Euch aus ihren Erlebnissen erzA�hlen und Eure Fragen ehrlich beantworten.
Wir freuen uns auf Euch.
Prof. Dr. Walid Maalej, Rebecca Tiarks und Mathias Ellmann
