Topics for Student Paper Presentation

Below are the topics of Web Science that will be addressed in the course. Each student will have to pick two papers of the same topic that she/he will present to the other students in the second part of the course. 

Subscription

Until 26.04.2019 send a mail to Philipp Kemkes with the following details:

  • 2 papers of the same topic that you wish to present.
  • Papers will be assigned to students according to the first come first served policy.

Hints:

  • Here we collected hints helping you to prepare a good presentation.
  • You can use the provided slide template for your presentation: powerpoint latex.

Exercise

At the end of April you should make an individual appointment with the mentor of your topic to discuss the selected papers. Thus you must read them until the meeting.

You have to meet the mentor of your topic again one week before your presentation during the exercise slot for a rehearsal talk. Hence your slides must be ready and you should have practised your talk already a few times.
