[Sigia-l] RE: first principals

[Avi Rappoport]

In my experience, Information Retrieval is about a great deal more 
than natural-language processing.  Many IR people do research on 
algorithms such as Latent Semantic Analysis, vector spaces, and other 
measures of similarity, as well as broader issues of distributed and 
federated retrieval, aboutness, information needs, visualization, 
cognition, citation analysis, user experience, alterting and 
collaborative filtering, and much more.

All this is fundamentally related to IA in interesting ways, 
providing a lot of fascinating if somewhat technical basic research.

My favorite IR book is

Modern Information Retrieval, Ricardo Baeza-Yates and Berthier 
Ribeiro-Neto. Addison Wesley, 1999.
