Hi, Is the RWR implementation in mahout 0.6 usable ?
Or what problem it has? If this implementation is usable, I will avoid reimplement it... Thank you !

You might want to have a look at Apache Giraph which offers an easy way to implement graph algorithms. RandomWalkWithRestart is essentialy the same as PageRank with the difference that the teleportation will only hit the source vertex of the walk not a random vertex in the graph. http://www.cs.cmu.edu/~ukang/papers/PegasusKAIS.pdf contains a short description.
