Welcome to the Wiki of the course '''Information Retrieval''' in the winter term 2013/2014

Here are the results for the official evaluation of this course.

Here you find information about the exam (including the PDF of the exam + a sketch of the solutions)

The course is given by Prof. Dr. Hannah Bast and assisted by Björn Buchhold. It takes place every Tuesday from 4:15pm until 5:45pm in the Hörsaal HS036 in building 101. The first lecture is on Tuesday, October 22, 2013 and the last lecture is on Tuesday, February 11, 2014. There will be no lecture on Tuesday, December 24, 2013 and Tuesday, December 31, 2013 (christmas break) and on Tuesday, Januar 7, 2014. That is 14 lectures altogether.

The tutors for this course are Stephanie Embgen (s.embgen@gmail.com), Jonas Sternisko (sternis@informatik.uni-freiburg.de) and Simon Skilevic (skilevis@informatik.uni-freiburg.de). The administrator of the supporting systems (Daphne, SVN, Forum, Jenkins) is Axel Lehmann.
