5. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 5 February 10, 2026 Course Goals ▪ In this seminar the student gets insights about recent developments in the field of Big Data systems. They will deepen their knowledge about specific topics in Big Data systems and are required to communicate the outcome to other course participants. The student should be able to critically review the assigned research papers, identify the main contributions and communicate the content in the form of a presentation as well as in a written report. ▪ The student is required to identify the contributions as well as strengths and weaknesses of a given research paper. They should further get an insight of how evaluate and position a research paper in the context of related work.
6. Beat Signer - Department of Computer Science - bsigner@vub.ac.be 6 February 10, 2026 Course Goals ▪ As part of the seminar the student is required to clearly communicate about the assigned research topic. The attendee shows that they can reflect on a given research topic and discuss it with colleagues by asking and answering scientific questions.
