A Self-Organising Multi-Agent Knowledge Base
(2021-12)
Digitale Städte sind zunehmend auf IT- und Kommunikationsinfrastruktur angewiesen. Sie können als große verteilte Systeme betrachtet werden, die aus heterogenen und autonomen Teilnehmern bestehen. Besonders in Notfall- und Krisensituationen muss kritisches Wissen, beispielsweise über verletzte Personen oder beschädigte Infrastruktur, zuverlässig auch unter eingeschränkter Kommunikation erreichbar sein. In einer solchen Umgebung würde eine zentrale Verwaltung des kritischen Wissens einen Engpass verursachen. Daher ...

Unleashing the Potential of Conversational Agents for Course Evaluations: Empirical Insights from a Comparison with Web Surveys
(Association for Information Systems, 2020)
Recent advances in Natural Language Processing (NLP) bear the opportunity to design new forms of human-computer interaction with conversational interfaces. However, little is known about how these interfaces change the way users respond in online course evaluations. We aim to explore the effects of conversational agents (CAs) on the response quality of online course evaluations in education compared to the common standard of web surveys. Past research indicates that web surveys come with disadvantages, such as poor ...

Towards Service Co-evolution in the Internet of Things
(2021-12)
Nowadays, in the world of technology, where the new technologies are devolved and replace the old ones every single day, any software product in order to maintain its competitiveness, must be updated continually. Updating a software product results from an evolution process, including adding new features, replacing outdated features, repairing bugs, closing security gaps, and improving performance, which requires a lot of effort and knowledge. Therefore, the Internet of Things (IoT) services are no exception.
An ...

SPAM – A Process Model for Developing Smart Personal Assistants
(ScholarSpace, 2020)
Information technology capabilities are growing at an impressive pace and increasingly overstrain the cognitive abilities of users. User assistance systems such as online manuals try to help the user in handling these systems. However, there is strong evidence that traditional user assistance systems are not as effective as intended. With the rise of smart personal assistants, such as Amazon’s Alexa, user assistance systems are becoming more sophisticated by offering a higher degree of interaction and intelligence. ...

On the requirements and advantages of cooperative collision avoidance systems for vulnerable road users
(2021-10)
Jedes Jahr sterben etwa 350.000 ungeschützte Verkehrsteilnehmer (engl. vulnerable road users (VRUs)), wie Fußgänger und Fahrradfahrer, durch Kollisionen mit Fahrzeugen. Ein Ansatz zur Verringerung dieser Zahl von Todesopfern ist der Einsatz von Kollisionsvermeidungssystemen für VRUs in Fahrzeugen. Diese fahrzeugbasierten VRU-Kollisionsvermeidungssysteme verwenden in den Fahrzeugen installierte Sensoren. Fahrzeugbasierte Kollisionsvermeidungssysteme sind bereits hilfreich, um Kollisionen zu vermeiden, funktionieren ...

Fine-scale grassland monitoring using unmanned aerial vehicle borne remote sensing
(2020-04)
RS is widely employed as a non-destructive methodology to monitor grasslands. Usage of UAV as the RS platform benefits to provide high spatial (fine-grain) and temporal resolution, unclouded data over small grassland extent. Therefore, this thesis evaluated the applications of UAV-borne RS for fine-scale grassland monitoring along with practical farm condition. Grass biomass estimation, predicting forage quality of grass and mapping invasive lupine in grasslands are considered as applications of UAVborne RS.

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 ...

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 ...
