3. Course contents *

The course covers the foundations of current ranking techniques (which are often based on statistical models), index structures, and current implementation issues for the design of effective and scalable information-system architectures. The course covers a wide range of ranking principles, starting from the Boolean retrieval model, over to statistical ranking models such as TF-IDF, and on to probabilistic ranking techniques such as Okapi-BM25. The course will cover classical IR topics, including link-analysis methods such as PageRank, the user-specific personalization of queries, and relevance feedback. 

The course topics are:


  • Boolean retrieval
  • Vector Space Model
  • Language Based Model
  • Boolean Independence Model
  • Top-K querying and Index construction
  • Index construction and compression
  • Feedback-Expansion
  • Evaluating IR
  • Link analysis
  • Dimensionality Reduction
  • Neighbor search in high dimensional data
