Subject Re: Clarification regarding inclusion of PageRank in Mahout
Date Tue, 05 Jul 2011 15:42:47 GMT
Pinging this question. Is there anyone who can propose a way to tackle 
this problem? Am I as PMC member in a position to contact Stanford and 
just ask about that patent issue? Id like to give it a try although it 
seems not very promising.
