Optimizing Mining Maximal Frequent Patterns with MFPAS
Posted on 29. Sep 2017; Supervised by Prof. Dr. Stefan Decker; Advisor(s): Dr. Michael Cochez, Rezaul Karim
Recently, a new approach for finding maximal frequent patterns (MFPAS) was presented by the supervisor and advisers of this thesis. Several further optimizations of the algorithm are possible. The student working on this thesis will experiment with different optimization possibilities and analyse their effect experimentally. For a master thesis, further theoretical analysis of the optimizations and the original algorithm are necessary. Related paper: M. R. Karim, M. Cochez, O. D. Beyan, C. F. Ahmed, and S. Decker.

Simulation tools for the Assessment of Emergency Management Processes
Posted on 12. Sep 2018; Supervised by Prof. Dr. Thomas Rose; Advisor(s): Thomas Osterland
Large scale disasters represent a major challenge for any medical service. Typically such disasters, be they founded in terrorism, natural or technical catastrophize, generate a significant number of casualties (MASCAL – Mass Casualty) with severe and unusual injury patterns. Many processes are supported by Standard Operating Procedures as common practice, but any catastrophe requires a change of processes due to the nature of the disaster and thus furnishes a major challenge for hospital operations. As of now, hospitals and medical services are designed for a specific workload that has been agreed among different stakeholders. Hence, processes and their resources are designed in light of best practices for patient care as well as anticipated workload.

Interactive Support for Business Modelling
Posted on 21. Jun 2017; Supervised by Prof. Dr. Thomas Rose; Advisor(s): Thomas Osterland
A business model is an abstract model of the business of one or more cooperating organisations. It is a conceptual and architectural implementation of a business strategy and the foundation for the implementation of business processes and information systems. The research objective of this thesis is the design, implementation and evaluation of an interactive tool for the engineering of a business model.

Measuring coherence accross media in learning environments
Posted on 28. Sep 2017; Supervised by PD Dr. Ralf Klamma, AOR, Prof. Dr. Marc Spaniol
Multimedia content based indexing delivered a lot of models for the analysis of multimedia materials. In modern educational platforms, e.g. MOOCs and self-regulated learning platforms. In consequence, multimedia materials are produced by educational designers but also by the learners during their learning processes. Coherence is a semantic measure for the local and global connectivity of e.g. sentences, paragraphs, videos, slides among others. Computer linguistics has provided impressive results for measuring the quality of writing, e.g. for automatic essay scoring. To measure the coherence of multimedia materials many computational methods reaching from natural language processing to machine learning needs to be combined in a common coherence model. Goal of this master thesis is to co-develop a coherence model for cross-media coherence and to prototypically combine these computational methods for a webinar.
Master

Reservation, booking and customer hotline services are based on context based dialog management. The objective of the thesis is the analysis of user interactions for different contexts in reservation, booking and customer hotline situations with a dialog management system and the design and implementation of a semantic model for the user dialog with a dialog management system. As proof of concept a functional prototype should be implemented and evaluated.
Master
Travel Information Dialog Service
Travel information services provide itinerary and context based user travel assistance. The objective of the thesis is the analysis of user interactions for different contexts in intermodal travel situations with a travel information assistance system and the design and implementation of a semantic model for the user dialog with a travel information assistance system. As proof of concept a functional prototype should be implemented and evaluated.

Evaluating the performance of all-pairs personalized page rank
Posted on 23. Oct 2017; Supervised by Prof. Dr. Stefan Decker; Advisor(s): Dr. Michael Cochez
Recently, a new approach for computing the personalized pagerank (PPR) for all nodes in a graph was presented by the adviser of this thesis. Personalized pagerank can be used to determine how important specific nodes in a graph are from the viewpoint of a specific node, or set of nodes. For example, it can be used to determine which web pages are relevant for a user, given a set of pages he has visited before. The improvement which the advisor of the thesis devised is useful when the PPR has to be computed for all nodes in the graph. The gain in speed is due to reuse of already computed PPR values for other nodes and a clever ordering of nodes. The student working on this thesis will experiment with this technique and others. First, the student needs to investigate ways to parallelize the algorithms and analyse the algorithms and their parameters experimentally. For a master thesis, the student has to improve the algorithm to optimize loops and experiment whether other improvements in the ordering pay of (i.e., whether other heuristics for finding the order work better and can be computed fast enough to speed up the overall algorithm). Besides, the student would investigate parallel computation of the order and actual PPR.

Developing a Data Annotation Tool for Scientific Data Management
Posted on 25. Oct 2016; Supervised by Prof. Dr. Stefan Decker; Advisor(s): Dr. Oya Deniz Beyan
Semantic technologies and RDF data representation can improve the reusability of scientific data and enable scientist to reproduce the experiments. However there is no tool to support researcher for making their data semantically interpretable by computers. Aim of the thesis is to understand the benefits of semantic web technologies for reproducible research and develop a tool which can convert experimental data to RDF by annotating with selected data models.

Machine Economy for Dynamic Configurations of Production Processes
Posted on 12. Sep 2018; Supervised by Prof. Dr. Thomas Rose; Advisor(s): Thomas Osterland
In the context of Industry 4.0 and the Internet of Things, the autonomization of cyber physical systems is increasingly coming to the fore. Just imagine an autonomous vehicle that offers commuter services against payment. The electric vehicle has to pay tolls, requires energy from charging stations and employs washing services from time to time. Considering all entities in this process as agents that can interact and carry wallets, one can easily envision a machine-to-machine economy. Technical agents decide what tasks to conduct regarding costs, capabilities and earnings as illustrated by the demonstrators of Smart Replenishment Box and Smart Vehicle Control1.
Master

Conversion from RDF to Prototype-based Knowledge Base
Posted on 24. Oct 2016; Supervised by Prof. Dr. Stefan Decker; Advisor(s): Dr. Michael Cochez
Prototypes have been proposed recently as a new way to represent knowledge. In recent years many datasets have been published using RDF. Your task is to find out how the RDF dataset can be converted to prototypes in an efficient manner. For a master thesis, you also have to work on the optimal conversion for different requirements such as updates in the original RDF data.
