Beer Recommendations With Graph Databases
Josh Adell explains how to extend a simple recommendation engine to similarity-based collaborative filtering:
Instead of basing recommendations off of one similar rating, I can calculate how similarly you and I rated all the things we have rated, and only get recommendations from you if I have determined we are similar enough in our tastes.
This is much closer to how recommendation engines developed by sites like Amazon or Netflix are working.
