Course synopsis

Web Information Retrieval refers to methods and technologies for search, analysis, and automatic organization of data collections in the World Wide Web: text documents, multimedia contents, structured and semi-structured knowledge representations. It has quickly become one of the most important areas in Computer and Information Sciences because of its direct applications in e-commerce, e-CRM, corporate knowledge bases and data repositories, Web analytics, and Web information systems.

The course will introduce mathematical models and algorithms widely used by Web search engines, intranets, and modern digital libratries. In doing so, we will consider state of the art techniques from linear algebra, statistics, graph mining and machine learning. The course will also provide a brief overview of other areas in Web mining, such as Web content mining and Web structure mining.

This course is part of the international Summer Academy (Track "Web Science - Engineering") and will be organized in a block form over the last weeks of the summer term 2012. Students from Uni Koblenz may attend this lecture (and earn ECTS credits) as a common course in their curriculum.

The course "Web Information Retrieval" will be held in parallel in two languages: English and Russian.

Key topics

  • Technical basics (linear algebra, stochastics, graph algorithms, text processing)
  • Content analysis - vector space models
  • Link analysis and authority ranking
  • Top-k retrieval
  • Multi-modal analysis of Web data
  • Thematically focused crawling
  • Search engine optimization


Basic knowledge in linear algebra, stochastics and graph algorithms. Recommended prerequisites are courses in data mining and database systems.


External students can earn credits per course (3 ECTS for Web Information Retrieval).

Internal diploma students earn credits per course OR have it as part of the oral diploma exam worth 3 ECTS / 2 SWS.

Internal master students in CV and Computer Science earn credit for the module INSS08 "Web Search & Data Mining" (offered by Prof. Dr. York Sure and Dr. Dr. Sergej Sizov), i.e. one joint module for two lectures with integrated exercises, together 6 ECTS = 4 SWS.

>> Schedule for the course in RUSSIAN


Individual oral exam (30 min) at the end of the course. Key topics of the oral exam 'Web Information Retrieval' include: basic methods of text mining and text retrieval; methods of link analysis and authority ranking; basics of search engine design and optimization.


External students: in order to attend the course, you have to apply for Summer Academy participation.

Internal students: the course is maintained in KLIPS  (English part under course ID 04179 and Russian part as a special course) as a common lecture and can be booked by regular studens in the usual way.
