Subject [jira] [Commented] (FLINK-3879) Native implementation of HITS algorithm
Date Wed, 29 Jun 2016 19:03:05 GMT

    [ https://issues.apache.org/jira/browse/FLINK-3879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15355664#comment-15355664

Vasia Kalavri commented on FLINK-3879:

You and I are the only Gelly component "shepherds", but that doesn't mean we are the only
ones that can review Gelly PRs. Any committer can help :)
I like the idea about improving our process. I went through the JIRAs last week and pinged
a few people, released some, closed some, but we can certainly clean up more.
Big +1 for roadmap => JIRA => implementation discussion => PR.
Do you think we should add this to the wiki /contribution guidelines / start a discussion
in the dev list?

>             Project: Flink
>          Issue Type: New Feature
>          Components: Gelly
>    Affects Versions: 1.1.0
>            Reporter: Greg Hogan
>            Assignee: Greg Hogan
>             Fix For: 1.1.0
> Hyperlink-Induced Topic Search (HITS, also "hubs and authorities") is presented in [0]
and described in [1].
> "[HITS] is a very popular and effective algorithm to rank documents based on the link
information among a set of documents. The algorithm presumes that a good hub is a document
that points to many others, and a good authority is a document that many documents point to."
> This implementation differs from FLINK-2044 by providing for convergence, outputting
both hub and authority scores, and completing in half the number of iterations.
