Probabilistic Models in Information Retrieval Introduction to probabilistic models. http://www.is.informatik.uni-duisburg.de/bib/xml/Fuhr_92.html

Information Retrieval Tutorial Description of boolean retrieval, vector space model, probabilistic retrieval, latent semantic indexing and other IR topics. An introduction to various classical ranking methods is also provided. http://isp.imm.dtu.dk/thor/projects/multimedia/textmining/

Document Ranking and the Vector-Space Model. It describes key issues in document ranking techniques based on the vector­ space model. Several TF*IDF variants are discussed. The cosine measure, recall and precision are introduced. [PS format] http://www.cs.ust.hk/~dlee/Papers/ir/ieee-sw-rank.ps.gz
