Digg Recommender July 29, 2008

Posted by Andre Vellino in Collaborative filtering.

I’m a little behind on my summer blogging (reading and writing) and seem to have missed Digg’s announcement for their recommendation feature.

I don’t Digg myself, but from the video demo (on the blog link above), it looks like they have struck a nice balance between pure collaborative filtering, topic classification and serendipity of recommendations (from different samples of users within a given similarity neighbourhood.)

Yes. I think that Digg has at least some good intentions. However, some observers have posted data that shows that Digg’s attempts at serendipity are actually making things worse.

Ah! If only there were a science preoccupied with these problems!
