CS 707: Data and Web Science Seminar (HWS 2020)

The Data and Web Science seminar covers recent topics in data and web science. This term the seminar focuses on Explainable AI (XAI).


  • This seminar is organized by Prof. Dr. Rainer Gemulla and Daniel Ruffinelli.
  • Available for Master students (2 SWS, 4 ECTS). If you are a Bachelor student and want to take this seminar (2 SWS, 5 ECTS), please contact Prof. Gemulla.
  • Prerequisites: solid background in machine learning
  • Maximum number of participants is 10 students


In this seminar, you will

  • Read, understand, and explore scientific literature
  • Summarize a current research topic in a concise report (10 single-column pages + references)
  • Give two presentations about your topic (3 minutes flash presentation, 15 minutes final presentation)
  • Moderate a scientific discussion about the topic of one of your fellow students
  • Review a (draft of a) report of a fellow student


  • Register as described below.
  • Attend the kickoff meeting on 7 October, 17:15, in A5 6, C015.
  • Work individually throughout the semester according to the seminar schedule.
  • Meet your advisor for guidance and feedback.


If you are an MSc student, register via Portal 2 until 28 September. If you are a BSC student, register via email to Daniel Ruffinelli until 28 September.

If you are accepted into the seminar, provide at least 4 topics of your preference (your own and/or example topics; see below) by 4 October via email to Daniel Ruffinelli. The actual topic assignment takes place soon afterwards; we will notify you via email. Our goal is to assign one of your preferred topics to you.


Each student works on a topic within the area of the seminar along with a accompanying reference paper. Your presentation and report should explore the topic with an emphasis on the reference paper, but not just the reference paper.

We provide example topics and reference papers below. These topics follows the taxonomy of a recent XAI survey by Arrieta et al. (2020), which see (Fig. 6). Each topic is associated with an example reference paper. If you want, you may suggest a different reference paper (let us know after the topic assignments) or a different topic within the XAI area (talk to use before the topic assignments). Other recent surveys include the one by Das and Rand (2020, preprint) and by Došilović et al. (2018). See also Google scholar.
