    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 04IN1021 (Web Information Retrieval) 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 2013.

    Students from Uni Koblenz may attend this lecture (and earn ECTS credits) for the  module "Information Retrieval" in their curriculum.

    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

    Pre-requirements

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

    Grading

    External students can earn credits per course (3 ECTS for 04IN1021 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 "Information Retrieval". The module includes the lecture "Information Retrieval" and the seminar "Advances in Information Retrieval", together 6 ECTS = 4 SWS. The seminar can be attended in the summer term 2013 as well, in parallel to the course.
