Web Information Retrieval[zur Übersicht]
Information Retrieval (IR) is dealing with the storage, representation and management of information items. In a classical setting the information items correspond to text documents. With the advent of the World Wide Web, the methods of IR have been transferred to retrieval on the web. This poses different challenges and has spawned the area of Web Retrieval.
The lecture will give an introduction in established retrieval models for text based documents, models that exploit the graph structure of the WWW, the topic of evaluating the performance of retrieval systems and related tasks like classification and clustering of web documents.
Web Information Retrieval (6 ECTS-Credits) is a lecture given in English that
- is a mandatory course for master students of Web Science
- can be taken as an elective course by bachelor and master students of Informatik and Computervisualistik, and by master students of Wirtschaftsinformatik and Information Management
- Re-Examination will be held on November 06 (Tuesday), 2018 from 18:00 hrs onwards at E-011
- The Final Examination will be held on July 30 (Monday), 2018 from 13:00 hrs onwards at D-028
- The lectures will start on April 16th, 18:00.

It is highly recommended that you follow a textbook while taking the lecture. The textbooks are probably able to address the most question you might have about the content of the lecture:
- Introduction to Information Retrieval. Manning, Raghavan, Schütze, Cambridge University Press, 2008.
Free, electronic versions available at http://informationretrieval.org/
- Web Data Mining. Liu. Springer, 2007.
- Modern Information Retrieval. Baeza-Yates, Ribeiro-Neto, ACM Press, 2012.
Students need to accomplish at least 50% of the assignments in order to attend the final exam. Plagiarism is strictly forbidden and will result in disqualification from the final exam, on both sides of the plagiarism (copying and being copied). Students are also expected to explain some of the assignments.
