Studying Business Information Systems Engineering

Topics for BSc./MSc. Theses

In the course of your studies, you will have to write a master's thesis and/or bachelor's thesis, depending on the course of study. During this time, you will acquire new specialist knowledge and learn the tools of independent development and research work under the guidance and supervision of a supervisor of your choice. Your first step towards successful work is to find an interesting topic for you. To do this, contact a research assistant who could supervise you. In your search for the right supervisor, please orient yourself on the subject area you are looking for and the research focus of the individual team members. Develop as precise an idea as possible of the topic you are interested in. Below you will find the current range of topics offered by the Chair of Information Systems. The list can be extended - in individual discussions with the academic staff.

The list below is not complete! Please also see the german descriptions if possible. Of course you can also always write the research staff of the institute for vacant research topics.

Bachelor Theses

Performance-Rating of Free-to-Use Triples-Stores

Supervisor: Achim Reiz

Suitable for: Bachelor

Language: English (prefered) or German

Date: 19.02.2020

Semantic services as a symbol-based artificial intelligence technology can be used in various application scenarios, e.g., enhancing deep-learning systems, autonomous driving, or knowledge-based systems. With SPARQL, there is a widely accepted query language standard available, allowing uniform access regardless of the underlying technology - similar to the SQL-standard for relational databases. But while the landscape of relational storage is highly mature and almost all SQL-based storage systems have high performances, this is not the case for triple-based databases. These, often research-driven developments, are more diverse regarding their functionalities and efficiency. This makes the selection of the right tool for the selected goals complex.
Your task is the evaluation of free-to-use RDF-based triple-stores like apache fuseki or virtuoso. Using uniform queries, you will measure the performance of the software and compare the expected results. Based on your findings, you can derive recommendations which database software is best to use for which application case.

Semantic Augmentation for Image Recognition

Supervisor: Achim Reiz

Suitable for: Bachelor or Master

Language: English (prefered) or German

Date: 05.01.2021

 

Open Images is a popular open-source dataset comprising of about 9 million annotated images. Developers can use it to train and set up domain-independent object recognition systems. With TensorFlow Hub, there is already a pre-trained neural network (NN) publicly available that can easily be integrated into existing applications, bypassing the need to train a new NN using the 550 Gb large Open Images repository. While the trained object detection delivers promising results, the detected items are isolated, and a shared context is missing. A high-level semantic is missing, allowing the interpretation of the results beyond the elements that are visible. Such can be achieved using ontology methods.

In 2020 we published SemOI - Semantic Augmentation for Open Images (The prototype is available on http://semoi.informatik.uni-rostock.de/). However, due to rather granular relations between the concepts, the accuracy of the detection is low. Your task is to improve the augmentation by revising the underlying ontology. Your first task is the definition of an augmentation goal and the corresponding high-level concepts. For example, one goal could be the detection of situations: A "car" and "tool" detected together could indicate a "repair"-situation. The next step is the modeling of these relationships. A performance evaluation concludes the research.

Standard Software for Participatory Budgeting (PB)

Supervisor: Achim Reiz

Suitable for: Bachelor

Language: English (prefered) or German

Date: 23.02.2021

 

Participatory Budgeting (PB) allocates a percentage of an administrations' budget for the direct democratic distribution. At the first stage, Citizens can propose new ideas, like park benches or an improvement of a playground. In the next step, all citizens can vote for the proposals they support the most. PB allows to use the limited financial resources of a municipality more efficiently and engages citizens in political decision-making, thus has the potential to strengthen democratic processes.

The use of IT-technologies often drives these initiatives by providing forms for uploading ideas, online forums for discussions, and virtual voting facilities. While municipalities often develop customized solutions, some standard software is available, like DecidimConsul, or citizens.is

Your task is a comparison of standard software for PB. The research shall begin with an extensive search in the internet and literature databases to find relevant software and their license, pricing model, and availability. In the next step, your task is the comparison of the identified software: What kind of features do they implement? What are the differences between these artifacts?

The research concludes with a software recommendation based on your identified advantages and shortcomings. 

Master Theses

Visualizing Ontology Evolution

Supervisor: Achim Reiz

Suitable for: Bachelor or Master

Language: English (prefered) or German

Date: 20.2.2020

Computational Ontologies offer a means for automated knowledge generation and have the potential to be a cornerstone for the upcoming challenges in the field of artificial intelligence.  
Their increased usage leads to a rising need for evaluation.
The OntoMetrics-tool (ontometricts.informatik.uni-rostock.de) of Rostock University provides a web interface for the calculation of ontology metrics. Recently, this tool was extended with a feature to analyze historical data based on git-repositories.
Currently, the tool does not offer advanced visual analysis capabilities. We argue that visualizing metric developments have the potential to significantly improve the intuitive understanding of the evolutional aspects of the ontology.
Your task is to research creative new ways to encode the analyzed data visually. As a preliminary step, the current state of the art regarding ontology visualization has to be collected. In the next step, you will build a front-end that enables the dynamic creation of diagrams based on a visualizing framework of your choosing (e.g., d3.js). These diagrams shall
1. provide an intuitive visualization of the metric development
2. set various variables into context with each other
3. be downloadable as a picture or pdf.
The research concludes with a validation of the usefulness of the newly created approach through a user-study.
