04IN1021-1 - 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. The concepts communicated in the lecture will be applied in practical exercises and tutorials.

More specifically the lecture will cover the topics:

  • Information seeking behaviour on the web and user models
  • Evaluation of retrieval systems
  • Boolean retrieval and essential data structures
  • Vector space retrieval model
  • Probabilistic information retrieval models
  • Language models
  • Cross language retrieval
  • Topic models
  • Web crawling
  • Authority ranking
  • Document clustering and classification
  • Information extraction
