Seminar Organization

We will offer both seminars (Bachelor’s and Master’s) in Winter 2026/27, together with Prof. Deßloch’s group.

Find some general information below:

Registration

To attend this seminar, students need to register according to the registration procedure. As in previous semesters, the registration process will be managed in a centralized manner for all of the CS department’s seminars, via OLAT courses. The assignment will of course reflect your specialization, prerequisite lectures (see below), and seminar wishes. You can find the password for the OLAT courses in the email the department well send or sent to you.

Seminar Overview

Once you get selected for our seminar, you will be able to select a research paper from a list of papers we provide. Each student needs to present their paper in a talk at the end of the semester. Finally, also a short report about the presented paper needs to be submitted, the latest two weeks after the presentation. More information will be provided in the kickoff meeting.

Prerequisites

  • Participants in the Bachelor Seminar should have successfully attended the core lecture Informationssysteme (information systems) or equivalent.
  • Participants in the Master Seminar should have successfully attended the core lecture Datenbanksysteme (database systems) or equivalent. Having attended the beginner’s course Informationssysteme (information systems), or equivalent, is assumed anyway.

Timeline

Remember the following deadlines if you got a slot in the seminar:

  • 23.10.26 14:00 Seminar Kickoff in 36-336 (slides)
  • 25.10.26 Paper Selection Deadline
  • 27.11.26 Summary & First Meeting Deadline (template)
  • 10.01.26 No-Left-ToDo Slides Deadline
  • TBD: Intro Talks (likely between 14.12.26 and 18.12.26)
  • TBD: Camera Ready Slides Deadline (2 days before presentations)
  • TBD: Final Presentations (likely between 08.02.27 and 12.02.27)
  • 28.02.27: report deadline

Papers

Look further than only titel and abstract before deciding for a paper, since some papers might demand math or deeper ML skills you might find difficult. You have to be in the University’s VPN (full tunnel) for accessing some of the papers.
