Towards a Technique for Modeling New Forms of Collaborative Work Practices – The Facilitation Process Model 2.0
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2020)
Collaboration Engineering (CE) is an approach for the design and deployment of repeatable collaborative work practices that can be executed by practitioners themselves without the ongoing support of external collaboration professionals. A key design activity in CE concerns modeling current and future collaborative work practices. CE researchers and practitioners have used the Facilitation Process Model (FPM) technique. However, this modeling technique suffers from a number of shortcomings to model contemporary ...

Crowd-Based Entrepreneurship
(2020)
The aim of this dissertation is to explore the innovation potential of crowdsourcing for entrepreneurship. The main focus is to discover how crowd-based infrastructures (i. e., crowdsourcing platforms and crowdfunding platforms) can support entrepreneurs in their innovation activities and how this new paradigm can be used to generate value for customers as well as actors of entrepreneurial ecosystems. The results of the dissertation show that crowdsourcing offers numerous opportunities to support entrepreneurs in ...

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 ...

Systematische Entwicklung eines Lerntools zur Erhöhung der Argumentationsfähigkeiten von Studierenden
(GITO Verlag, 2020)
Die Digitalisierung führt zu neuen Anforderungen an Fähigkeiten und Kenntnissen, die Studierende in ihrem zukünftigen Berufsleben benötigen. Metakognitive Lernkompetenzen und Higher Order Thinking Skills werden dabei immer wichtiger, um Herausforderungen der Zukunft zu lösen. Eine Unterklasse dieser Fähigkeiten, die wesentlich zu Kommunikation, Kollaboration und Problemlösung beiträgt, ist die Fähigkeit, strukturiert und reflektierend zu argumentieren. Bildungseinrichtungen haben jedoch Schwierigkeiten, die für die ...

On data-driven nonlinear uncertainty modeling: Methods and application for control-oriented surface condition prediction in hard turning
(2020-10-16)
In this article, two data-driven modeling approaches are investigated, which allow an explicit modeling of uncertainty. For this purpose, parametric Takagi-Sugeno multi-models with bounded-error parameter estimation and nonparametric Gaussian process regression are applied and compared. These models can for instance be used for robust model-based control design. As an application, the prediction of residual stresses during hard turning depending on the machining parameters and the initial hardness is considered.

Analyzing Given Names
(2020)
Computer science has evolved so much that it influences almost every part of human live. A particularly personal part of human live is the selection of a given name for a newborn baby. The name discovery service Nameling is our way to help expectant parents with this decision. It is a web service that helps parents to find a given name for their newborn baby. We want to further improve the user experience of Nameling by personalizing its name results for the current user. We deem this important, because the selection ...

Symbolic Representation of Dynamic Knowledge for Robotic Teams
(2020-11)
Das Forschungsziel dieser Arbeit ist es, die konzeptionellen Grundlagen für ein Team autonomer Roboter zu entwickeln, welches in der Lage ist, Wissen über seine Umwelt symbolisch darzustellen, über sein symbolisches Wissen zu kommunizieren und mit dem Wissen zu schlussfolgern, während sich die Umgebung dynamisch ändert. Dieses Forschungsziel wird durch mehrere Anwendungsbereiche motiviert, wobei die Domäne der Haushaltsroboter das Forschungsziel am besten motiviert. Wir haben die Anwendungsdomänen und das Forschungsziel ...
