Information Retrieval

General Information

This web page gives information on the lecture 'Information Retrieval' which is held during the winter term 2017/2018 by Tatiana Gossen. It will be constantly updated during the course.

Information retrieval focuses on obtaining, extracting or mining information from a large collection of unstructured data, e.g. in form of text documents, images or videos. Information retrieval concepts are applied in web search engines, digital libraries and multimedia archives such as image and video databases. In this course the foundations of information retrieval will be introduced and illustrated on some specific application areas.

Please register yourself via LSF for one of the exercises!

Master students, please note that this course is 5CP only!

Requirements for Participation in the Final Exam

All students are required to participate in the exercise classes. Every week, there will be an assignment sheet that will be handed out one week in advance. This sheet has to be prepared by every student and will be discussed in class. There are two different types of assignments: theoretical tasks and programming assignments. The programming assignments can be solved in small groups of up to three students and must be sent in before the respective deadline. Prerequisites for a written exam and a 'Schein' is fulfillment of the following criteria:

  • at least 50% of all programming points,
  • at least 66% of votes for all other exercise tasks and
  • at least two presentations of a solution in front of the class.

For acquiring the "Schein" you have to write and pass the exam.

A general reminder: In accordance with the examination rules, we offer each student exactly one examination date (oral or written) each term. The registration for a follow-up examination is only possible in the next term (i.e. after 6 months). As soon as a student has registered for an exam, either by using the LSF for written exams or by filling in the information on an examination list for oral exams (or filling out a registration form), this is counted as the agreed examination date. If it is cancelled, the rule above applies.
