What is the “killer use case” for Reasoning, i.e., inferencing over a semantic graph database? Data in a relational database “knows nothing.” Data in a graph database “knows how it is connected” – you can ask an entity to tell you who its neighbors are 3 hops out, or if two pieces are connected up to 20 hops. Data with Reasoning “knows how to think.” But what does that mean exactly? What do you get?
