Resolution: Fixed
Patch applied.
> 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
> Attachments: patch.txt
>
> 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.
