Hi, I’m going to build a recommendation engine for our Intranet, which  
aims to recommend content and connections based on data that is stored  
in our database, such as tags, user-info etc.

Anyone know of a good place to start? Are there any plugins, howtos,  
books that would guide me in the right direction?

Happy for all the direction I can get. Merry christmas!

Hey! So far it’s going pretty slow, I’ve worked with this as a starting  
point:  
[http://www.igvita.com/2007/01/15/svd-recommendation-system-in-ruby/](http://www.igvita.com/2007/01/15/svd-recommendation-system-in-ruby/)

My math-skills are a bit rusty, but I’m getting there 😉 If I have time  
I’ll extract it and post it here!

Best of luck!
