[jira] Commented: (NUTCH-240) Scoring API: extension point, scoring
filters and an OPIC plugin
[ http://issues.apache.org/jira/browse/NUTCH-240?page=comments#action_12377200 ]
Andrzej Bialecki commented on NUTCH-240:
-----------------------------------------
If there are no further suggestions or objections, I'd like to move forward on this patch. I know the passScore* methods are a bit awkward, but that's what we do anyway, we just do it under the carpet :)
If folks have ideas how to improve this part, please speak up.

> This patch refactors all places where Nutch manipulates page scores, into a plugin-based API. Using this API it's possible to implement different scoring algorithms. It is also much easier to understand how scoring works.
> Multiple scoring plugins can be run in sequence, in a manner similar to URLFilters.
> Included is also an OPICScoringFilter plugin, which contains the current implementation of the scoring algorithm. Together with the scoring API it provides a fully backward-compatible scoring.
