OPIC score for outlinks should be based on # of valid links, not total # of
links.
----------------------------------------------------------------------------------
Key: NUTCH-230
URL: http://issues.apache.org/jira/browse/NUTCH-230
Project: Nutch
Type: Improvement
Versions: 0.8-dev
Reporter: Ken Krugler
Priority: Minor
In ParseOutputFormat.java, the write() method currently divides the page score
by the # of outlinks:
score /= links.length;
It then loops over the links, and any that pass the normalize/filter gauntlet
get added to the crawl output.
But this means that any filtered links result in some amount of the page's OPIC
score being "lost".
For Nutch 0.7, I built a list of valid (post-filter) links, and then used that
to determine the per-link OPIC score, after which I iterated over the list,
adding entries to the crawl output.
