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.

Design Criteria for Participatory Budgeting Tools

Supervisor: Achim Reiz

Suitable for: Bachelor or Master

Language: English (prefered) or German

Date: 23.01.2020

Participatory budgeting (PB) is a process of democratic decision-making, in which ordinary people take part in the preparation and adoption of a municipal or public budget. The EmPaci project aims to strengthen the use of PB within the Baltic Sea Region. With project partners from almost all littoral states - Russia, Finland, Poland, Lithuania, Latvia - the goal is to learn from each other and to provide best practices for the introduction of PB-Processes.
The chair of business informatics at Rostock University is responsible for the research on IT-capabilities. This includes the identification of relevant usability criteria and is the starting point for your thesis. The following research tasks are

  1. Taking relevant literature and trustworthy internet resources, you will discover best practices regarding the design of web pages.
    RQ 1: What is the state of the art in web page design?
  2. In the next step, these general recommendations are compared to characteristic features of public websites.
    RQ 2: What are the specific features/requirements of a public internet presence
  3. In the latter, a set of PB initiatives from project partners and successful municipalities are to be evaluated using your identified criteria.
    RQ 3: How do current PB-initiatives perform from a usability point of view

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.
