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. There will be no session on Wednesday, December 25, 2013, on Wednesday, January 1, 2014 (christmas break) and on Wednesday, October 30, 2013.
Information Extraction is the task of extracting (structured) information from natural language text. We will cover interesting topics in this area with a focus on current state-of-the-art systems for Open Information Extraction. We will also cover the NLP background required for understanding.
