I’m looking to use an inverted index for Ruby. There used to be Zed
Shaw’s Ruby/odeum that did this using QDBM’s inverted index API. I can
find references to this all over the web, unfortuntely but the original
site is gone and I can’t find any mirrors.

Can anybody help me out?

If not maybe you would care to explain what is an inverted index please
;).

you can find the project page on the internet archive [1] and the
gem on rubyforge (gem install ruby_odeum). is that what you’re after?

An inverted index is an index from terms to the documents that they
appear in. Typically drawn as:

word1 → doc1, doc2, doc3, doc4
word2 → doc1, doc4, doc7, doc12
word3 → doc5, doc6, doc7, doc12

It could be expressed as a Hash of Arrays, but when you start
operating on even medium-small text collections, it can get
inefficient to load the whole thing into RAM when you don’t need
to.

Don’t forget about Ferret. http://ferret.davebalmain.com/trac

Also If you can wait a week or so, I’m working on a preliminary ruby
interface
to Tokyo Dystopia.

Unfortunately they don’t mirror the actual gems.

In the end I found that version 0.2.1 is on Rubyforge (somewhere – a
search on the website didn’t find a project responsible for maintining
it, but I found the gem in RubyGems), and I somehow got my hands on an
0.4 gem which I have mirrored at http://www.iit.edu/~kbloom1/ for the
time being, until I find something better to do with it.

Zed still has all the software on his web site - just no links into it

http://www.zedshaw.com/downloads/ruby_odeum/ruby_odeum-0.4.1.tar.bz2

the gem is here

Google REALLY is your friend.

well, they do. if you go to the latest page [1] (Dec 31, 2007 ) and
follow the “download a gem” link for the latest release (0.4.1) you
get [2].
