Dr. Oliver Karras

Post-Doc & Data Scientist

Oliver Karras works as a Data Scientist at the Data Science and Digital Libraries Research Group at TIB. He holds a Bachelor of Science and a Master of Science degree as well as a PhD in Computer Science from Leibniz Universität Hannover. He is involved in the research project Open Research Knowledge Graph (ORKG) on the one hand and in the National Research Data Infrastructure for Engineering Sciences (NFDI-4ing) consortium, which is part of the National Research Data Infrastructure (NFDI), on the other hand. As part of this work, his research addresses the development of the Open Research Knowledge Graph for application to engineering science. The focus is on the formalization, discoverability, and accessibility of methodological knowledge and information on semantically rich and machine-interpretable concepts for engineering problems.

He is a member of the Gesellschaft für Informatik e.V. (GI), deputy spokesperson of the Fachgruppe Requirements Engineering (RE), and a regular reviewer and member of various program and organizing committees of conferences and journals.

Before joining TIB, he was a research assistant and PhD student at the Software Engineering Group at Leibniz Universität Hannover. He served as project leader of the DFG research project ViViReq and researched the integration of videos as a complementary communication medium in requirements engineering. His research focused on supporting requirements communication between stakeholders and the development team to foster the development of a shared understanding of the project vision of the system under development among all project partners involved. He has published his research in over 35 national and international publications covering diverse topics such as requirements engineering, social software engineering, machine learning, and natural language processing.


His research interests are in the areas of:

  • Data Science, Artificial Intelligence, Knowledge Representation, Engineering & Management
  • Software Engineering and Requirements Engineering
    • Software Development
    • Empirical Research
    • Requirements Communication
    • Shared Understanding
    • Knowledge Transfer
    • Vision Videos
  • Human Computer Interaction
    • User Interface Design
    • User Experience
