  • Models (boolean, fuzzy, vector space, probabilistic retrieval, Web retrieval) . Evaluation (effectiveness vs efficiency, relevance, metrics for boolean retrieval, evaluation of linear rankings)
  • Interactive Retrieval (information seeking behavior; information search; system functions, user interfaces)
