How to create a recommendation / similarity mechanism

Question

I am looking for methods to create a recommendation mechanism. I use the full-text sphinx engine.

Answer 1

You really have to look at what processes the relationship. What you want is what the graph implements (for example, nodes and edges), then you use the graph traversal to find nodes that match your criteria. This simplifies it, but the recommendations are not easy.
