“Take, for example, the enduring challenge in analytics of combining data from disparate sources and have it make some sort of sense. Perhaps I’m a simpleton, but just framing it that way makes me immediately respond, “meaningfully combining data from heterogeneous sources is a knowledge graph’s main value proposition.”  And while there’s other means of combining those bits, the semantics allow you to both describe those connections, and to enduringly connect that data rather than endlessly transforming it.”
