Welcome to the Wiki of the seminar ''Information Extraction'' in the winter semester 2013 / 2014

This seminar will be given by Elmar Haußmann and Sabine Storandt, from the chair of Prof. Dr. Hannah Bast (who will also attend the sessions). The seminar will take place every Wednesday, 4:00 pm - 6:00 pm ct., in the seminar room 00-007 in building 106.
