Recommendation Systems Gone Bad

Xeni at BB notes an offensive – though not clearly intentional – result at Walmart.com.

This product listing on Wal*Mart’s website for a Planet of The Apes DVD suggests films about black historic figures Dorothy Dandridge and Martin Luther King, Jr. as “similar items.”

Reader comments continue:

I recall seeing something like this before. In that case, inappropriate Amazon books were recommended, such as sex guides being shown for people browsing a Pat Robertson book. It was theorized that a large number of people caused this by visiting one page then the other, in order to game the system.

Perhaps the same thing is happening here.

We all know about Google Bombing. But Recommendation System Bombing? That’s a new one to me!
