Peter de Lange, M.Sc. - Theses


Bachelor, Master
Blockchain-based Verification of Learning Analytics Data - Open
The goal of this thesis is to make collected Learning Analytics data, extracted from various Learning Management Systems, traceable and verifiable by keeping a reference to the monitored data on the las2peer Blockchain. The thesis should investigate related work in the domain of educational usage of Blockchain technology. The developed extension should integrate into the existing project's infrastructure and provide learners and their mentors/tutors with a tool to explore when and what kind of data was collected. By improving this traceability, we hope to increase the trust in the data collection (and its usage) from both learners and mentors.
Bachelor, Master
Secure and User-friendly Authentication for a Decentralized Service Platform - Open
The goal of this thesis is the development of a secure and user-friendly authentication system for las2peer. Conceptually, it should be build on / support the aforementioned existing features of las2peer, namely the blockchain-based verification system and the OpenId Connect standard. Technically, these two systems should be integrated within a modern Web authentication flow, supporting the WebAuthn standard and integrating Decentralized Identifiers. The resulting implementation should be fully compatible with existing authentication scenarios of las2peer and provide users with an optional extra layer of security.
Master
Utilize Chat Interfaces for Social Bot Creation - Open
Social Bots (software robots) are computer algorithms that automatically produce content and interact with humans on social media. This thesis will utilize chat interfaces and a social bot framework to create social bots. It will also extend the framework to support various social bot types (e.g. chatbots, crawlers, transactional bots or informational bots).
Bachelor, Master
Versioning and Access Management in Web-Based Collaborative Model-Driven Web Engineering - Open
Modern collaborative development practices use agile principles to structure and organize the development process. The tool support for this includes source code management, with the large majority of development teams using Git. While collaboration patterns and access management of cooperation on source code is studied quite well, for MDWE (Model-Driven Web Engineering) processes, where collaboration happens on models instead of (only) source code, this is not yet the case. The thesis should investigate possibilities of versioning and access management for an existing MDWE platform.
Bachelor
Web-based Cluster Deployment for a Large-Scale Distributed Infrastructure - Open
Nowadays, agile development processes use cloud container orchestration platforms for continuous integration, deployment and delivery. Technologies like Docker and Kubernetes are used here as the state-of-the-art cloud-native infrastructures the software is deployed on. However, deployment of heterogeneous service environments, developed by multiple teams with different technical proficiency levels, is not a trivial task. The thesis should investigate possibilities of automatic Web-based deployment of microservices in a Kubernetes cluster.
Bachelor
A Multimodal Mentoring Cockpit for Tutor Support - Finished
Completed by Philipp Roytburg in 2019; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Dr. Matthias Jarke; Advisor(s): Peter de Lange, M.Sc., Alexander Tobias Neumann, M.Sc.
Learning analytics aim at providing an insight into the student’s learning process such that individual performance can be measured and thus provide the basis for individual student support. This thesis will utilize and evaluate existing mentoring solutions and aggregate them in a state-of-the-art progressive Web application. The outcome of this thesis will be a newly developed mentoring cockpit that meets the requirements of a holistic mentoring support experience.
Bachelor
Chat Interfaces for Social Bots in a Peer-to-Peer Environment - Finished
Completed by Niels Wießner in 2019; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Dr. Matthias Jarke; Advisor(s): Peter de Lange, M.Sc., Alexander Tobias Neumann, M.Sc.
Social Bots (software robots) are computer algorithms that automatically produce content and interact with humans on social media. This thesis will utilize and evaluate a social bot framework with different community applications. It will also extend the framework to support two-way chat interfaces with the system via common chat applications (e.g. Slack).
Master
Decentralized Service Registry and Discovery in P2P Networks with Blockchain Technology - Finished
Completed by Tom Janson in 2019; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Dr. Matthias Jarke; Advisor(s): Peter de Lange, M.Sc.
The goal of this thesis is the development of a distributed service registry and discovery system for las2peer. Conceptually, it should be built on the aforementioned previous results, namely the service discovery system, the application store and the community success measurement system. Technically, a blockchain-based solution should be developed that both allows and enforces developers to add their services to a community-blockchain, which can be used for authenticating service-origin as well as for inspection of available services throughout the network, including a connection to their success measurement.
Master
Model-Driven Construction & Utilization of Social Bots for Technology Enhanced Learning - Finished
Completed by Neumann, Alexander in 2018; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Dr. Matthias Jarke; Advisor(s): Peter de Lange, M.Sc.
Social Bots (software robots) are computer algorithms that automatically produce content and interact with humans on social media.
