As far as I know, Nutch uses OPIC to calculate scores for urls for its on-line efficiency. Whereas, LinkRank is an alternative way to achieve that. In the current version of Nutch, you can only use it separately. After that, scores of urls in WebDB pre-calculated by OPIC can be updated. For more information related to this topic, refer to wiki of Nutch or relative code sources in the webgraph package. There are several separate commands related to it. This is my own opinion, and I will be very grateful if you can point out something wrong.
