Andrzej Bialecki closed NUTCH-240:
-----------------------------------
Fix Version: 0.8-dev
Resolution: Fixed
Patches applied. Any further API improvements are welcome, the current API is
less than ideal but allows experimenting with various scoring strategies, which
is IMHO more important at this moment than API purity.
> Scoring API: extension point, scoring filters and an OPIC plugin

> 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.
