[ http://issues.apache.org/jira/browse/NUTCH-324?page=all ]
Stefan Groschupf updated NUTCH-324:
-----------------------------------
Attachment: InternalAndExternalLinkScoreFactor.patch
Multiply the score of a page during distributeScoreToOutlink with
db.score.link.internal or db.score.link.external.
> db.score.link.internal and db.score.link.external are ignored
> -------------------------------------------------------------
>
> Key: NUTCH-324
> URL: http://issues.apache.org/jira/browse/NUTCH-324
> Project: Nutch
> Issue Type: Improvement
> Components: fetcher
> Reporter: Stefan Groschupf
> Priority: Critical
> Attachments: InternalAndExternalLinkScoreFactor.patch
>
>
> Configuration properties db.score.link.external and db.score.link.internal
> are ignored.
> In case of e.g. message board webpages or pages that have larger navigation
> menus on each page having a lower impact of internal links makes a lot of
> sense for scoring.
> Also for web spam this is a serious problem, since now spammers can setup
> just one domain with dynamically generated pages and this highly manipulate
> the nutch scores.
> So I also suggest that we give db.score.link.internal by default a value of
> something like 0.25.
