Subject Re: Mixing simiarity measures

Thanks for all the comments. They give us idea on what direction to take.

We have been zeroing on idea of Random Indexing, but R.I seems missing in
mahout currently. Are there future plans for implementing R.I in mahout?
Any libraries out that that would be useful for R.I?
