[ http://issues.apache.org/jira/browse/NUTCH-240?page=comments#action_12372341 ]
Doug Cutting commented on NUTCH-240: ------------------------------------ The generator store/restore score stuff seems ugly. And it is not used by OPIC. Could we insteadhave a method that computes and returns a score to be used by the generator? Then it is up to the generator to use this w/o modifying the CrawlDatum. The passScoreBeforeParsing/passScoreAfterParsing/distributeScoreToOutlink protocol also seems awkward, although I don't yet have a suggestion for how to improve it. > Scoring API: extension point, scoring filters and an OPIC plugin > ---------------------------------------------------------------- > > Key: NUTCH-240 > URL: http://issues.apache.org/jira/browse/NUTCH-240 > Project: Nutch > Type: Improvement > Versions: 0.8-dev > Reporter: Andrzej Bialecki > Attachments: patch.txt > > 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
