hi Ting,

Have a look at the "scoring-opic" plugin and the package "
org.apache.nutch.scoring.*".

"opic" is the algorithm used by nutch to determine a page's static
importance. Basically speaking it does the same job as google's pagerank
algorithm.

some issues (probarbly fixed?) regarding the implementation (link to the
original opic-paper can be found there) :
http://wiki.apache.org/nutch/FixingOpicScoring

regarding the issues - sombody just got (or tries to get) his hands on the
opic-plugin. Probably you want to keep an eye on that thread:
