Subject [jira] [Commented] (GIRAPH-584) Giraph implementation of Nutch LinkRank Algorithm
Date Wed, 27 Mar 2013 09:23:15 GMT


Sebastian Schelter commented on GIRAPH-584:

Looks like a very good idea. I have a few suggestions: AFAIK, LinkRank is a slight modification
of PageRank and also relies on doing a random walk on the link graph. We already have some
tooling for doing this (see GIRAPH-480 for latest developments) that should be leveraged.

Furthermore, it would be great to get some performance numbers on a large graph. E.g. you
could use the Webbase dataset which has more
than a billion links.

> This issue is initially aimed at the delegation of the Nutch page rank mechanism (called
LinkRank) to Apache Giraph.
> Motivation for this is simple, we envisage that this would probably save us quite a bit
of code and be more efficient.
> The idea is to attract and build interest around this issue and propose it for this years
Google Summer of Code.
> We would like to build links between the Giraph and Nutch communities and make both Nutch
and Giraph better in the process.
