> Relevance based scoring filter
> ------------------------------
>
> Key: NUTCH-2039
> URL: https://issues.apache.org/jira/browse/NUTCH-2039
> Project: Nutch
> Issue Type: New Feature
> Reporter: Sujen Shah
> Labels: memex, nutch
> Fix For: 1.11
>
>
> A ScoringFilter plugin that uses a similarity measure to calculate the
> similarity between a given page(gold standard) and the currently parsed page.
> The score obtained from this similarity is then distributed to its outlinks.
> This filter aims to focus the crawler to crawl/explore relevant pages.
