The main goals of this dissertation are to uncover the underlying processes of internal interruptions and observe it in real ...

Engaging Learners in Online Video Lectures with Dynamically Scaffolding Conversational Agents
(Association for Information Systems, 2020)
Online education creates new opportunities for learners, which has led to sharply increasing enrollment in the last few years. Despite these benefits, past research shows that the lack of individual interaction with educators creates low learner engagement that leads to high attrition rates, which remains a major challenge in the field. Dynamically scaffolding conversational agents built into online video lectures promise to address this problem by individually interacting with learners, similar to educators’ scaffolding ...

Using Smart Personal Assistants for Online Learning Activities: What benefits can we expect?
(GITO Verlag, 2020)
With the increasing popularity of massive open online courses, universities are able to reach a wider audience without restriction and for comparably low costs. However, in these learning environments, educators are hardly able to offer individual support to their learners. According to learning theory, the lack of individual support in online learning environments can considerably limit learning success. In our paper, we argue that new emerging Smart Personal Assistants (SPAs) have the capabilities to address this ...

Designing a Conversational Agent as a Formative Course Evaluation Tool
(GITO Verlag, 2020)
Today’s graduating students face ever-changing environments when they enter their job life. Educational institutions must therefore continuously develop their course structure and content in order to prepare their students to be future employees. A very important means for developing the courses is the students’ course evaluations. Due to financial and organizational restrictions, these course evaluations are usually carried out quantitatively and at the end of the semester. However, past research has shown that this ...

Unlocking Transfer Learning in Argumentation Mining: A Domain-Independent Modelling Approach
(GITO Verlag, 2020)
Argument identification is the fundamental block of every Argumentation Mining pipeline, which in turn is a young upcoming field with multiple applications ranging from strategy support to opinion mining and news fact-checking. We developed a model, which is tackling the two biggest practical and academic challenges of the research field today. First, it addresses the lack of corpus-agnostic models and, second, it tackles the problem of human-labor-intensive NLP models being costly to develop. We do that by suggesting ...

Trust in Smart Personal Assistants: A Systematic Literature Review and Development of a Research Agenda
(GITO Verlag, 2020)
Smart Personal Assistants (SPA) fundamentally influence the way individuals perform tasks, use services and interact with organizations. They thus bear an immense economic and societal potential. However, a lack of trust - rooted in perceptions of uncertainty and risk - when interacting with intelligent computer agents can inhibit their adoption. In this paper, we conduct a systematic literature review to investigate the state of knowledge on trust in SPAs. Based on a concept-centric analysis of 50 papers, we derive ...
