Towards Empowering Educators to Create their own Smart Personal Assistants
(ScholarSpace, 2020)
Despite a growing body of research about the design and use of Smart Personal Assistants such as Amazon’s Alexa or Google’s Assistant, little is known about their ability to help educators offering individual support in large-scale learning environments. Smart Personal Assistant ecosystems empower educators to develop their own agents without deep technological knowledge. The objective of this paper is to design and validate a method that helps educators to create Smart Personal Assistants as learning tutors. Using ...

Identification of individuals and groups in a public goods experiment
(2019-07-03)
Revealing the identities of contributors has been shown to increase cooperation in public goods games. In this paper we experimentally investigate whether this finding holds true when decisions are made by groups rather than individuals. We distinguish between groups in which members can discuss face-to-face to reach a decision and groups in which members communicate via computer chat. The results confirm the positive effect of identification on cooperation among individuals. For groups, however, we only find a small ...

Towards A Taxonomy of Text Mining Features
(Association for Information Systems, 2019)
Recently, text mining has received special attention from both researchers and practitioners, since it enables the development of intelligent and automated services. Text mining has been influenced by different disciplines like computer science, statistics, computational linguistics and library and information sciences. However, text mining features that evolved in one particular discipline are often unknown or rarely used in the other disciplines. No scientific feature framework exits which facilitates costly feature ...

Voting on the threat of exclusion in a public goods experiment
(2019-04-01)
Ostracism is practiced by virtually all societies around the world as a means of enforcing cooperation. In this paper, we use a public goods experiment to study whether groups choose to implement an institution that allows for the exclusion of members. We distinguish between a costless exclusion institution and a costly exclusion institution that, if chosen, reduces the endowment of all players. We also provide a comparison with an exclusion institution that is exogenously imposed upon groups. A significant share of ...

Gestaltung smarter persönlicher Assistenten zwischen Rechtsverträglichkeit und Dienstleistungsqualität
(Gesellschaft für Informatik e.V. (GI), 2019)
Smarte persönliche Assistenten von Amazon, Google und zahlreichen anderen Anbietern ermöglichen es, qualitativ hochwertige elektronische Dienstleistungen anzubieten. Gleichzeitig bringen diese Systeme auch viele Risiken mit sich. Berichte von diskriminierenden oder unverständlichem Systemverhalten häufen sich und verursachen Skepsis in der Gesellschaft. Diesen Problemen kann mit einer gleichermaßen rechtsverträglichen und qualitätsorientierten ITGestaltung entgegengewirkt werden. In diesem Beitrag werden Rechtsvert ...

Alexa, Can You Help Me Solve That Problem? - Understanding the Value of Smart Personal Assistants as Tutors for Complex Problem Tasks
(universi - Universitätsverlag Siegen, 2019)
In recent decades, the number of students per lecturer at universities has constantly risen. In these learning scenarios, individual lecturer support for helping students actively acquiring new knowledge is hardly possible. However, active student behavior is necessary for successful learning. Smart Personal Assistants such as Amazon’s Alexa or Google’s Home promise to fill this gap by being students’ individual tutors. In order to understand what students expect from Smart Personal Assistants as tutors and how they ...
