= Welcome to the Wiki of the seminar ''Information Extraction'' in the winter semester 2013 / 2014 =
This seminar will be given by [[http://ad.informatik.uni-freiburg.de/staff/haussmann|Elmar Haußmann]] and [[https://ad.informatik.uni-freiburg.de/staff/storandt|Sabine Storandt]], from the chair of [[http://ad.informatik.uni-freiburg.de/staff/bast|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, November 6, 2013. Therefore, depending on the number of talks/participants, we will have at most 14 sessions.

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.

== Topics ==

The topics and dates will be assigned in the first sessions. Here is a tentative list of topics and systems (each of which will be roughly explained in the first session):

 * NLP Basics 1/2 (POS tagging, chunking, NER, NED)
 * NLP Basics 2/2 (constituent / dependency parsing, SRL)
