I just completed an introductory course in IR. I can recommend the textbook we used: "Managing Gigabytes: Compressing and Indexing Documents and Images". When I don't understand posts on this list I can typically look up the theory in that book, then come back to the list and have a better idea of whats going on. "Managing Gigabytes" appears to be getting good reviews from most readers, but I can't compare it to similar works as I haven't read any.
I've spent some time searching for websites that introduce advanced IR topics at a level that is less rigorous than academic papers. But I haven't really found anything I can recommend. Suggestions welcome :)

Hi,
I might be the only person on the list who's having a hard time following this discussion. Would one of you wise folks care to point me to a good "dummies", also known as an executive summary, resource about the theoretical background of all of this. I understand the basic premise of collecting the "words" and having pointers to documents and weights, but beyond that ...
TIA,
Dror

i don't know of any open source search engine that incorporates interterm correlation. i have been looking into how to do this in Lucene and so far, it's not been promising. the indexing engine and file format needs to be changed. there are very few search engines that incorporate interterm correlation in any mathematically and linguistically rigorous manner. i designed a couple, but they were all research experiments.
if you are familiar with the TREC automatic adhoc track? my experiments with the TREC-5 to TREC-7 questions produced about 0.05 to 0.10 improvement in average precision by proper use of interterm correlation. my project at the time was cancelled after TREC-7 and so there haven't been any new developments.

Hmm... Are you perhaps familiar with some open system which doesn't? I'm curious because one of my projects (already using Lucene) could benefit from such feature. Right now I'm using a bastardized version of Markov chains, but it's more of a hack...
