How does Flickr’s interestingness ranking work?

Tags: Filed under: Written in Englishhugo @ 13:06

I’m really wondering how Flickr orders photos by interestingness.

Here’s the attributes of ours:

  1. 30 views / 1 person counts this as a favorite / 0 comments
  2. 5 views / 1 person counts this as a favorite / 1 comment
  3. 26 views / 1 person counts this as a favorite / 2 comments
  4. 51 views / 1 person counts this as a favorite / 3 comments
  5. 17 views / Nobody counts Mac dudes as a favorite / 4 comments
  6. 45 views / 1 person counts this as a favorite / 0 comments
  7. 36 views / Nobody counts France vs Cyprus – 2005-10-12 – 4-0 as a favorite / 1 comment
  8. 6 views / 1 person counts this as a favorite / 0 comments
  9. Etc.

This looks random to me.

    Reading Paul’s entry on this subject, I thought about this again. Looking only at Flickr data we have (i.e. not the undisclosed factors Paul talks about), we could have a formula like:

    interestingness = (views + 2 * comments + 5 * favorites) * age(account) / age(picture)
