Terminology alert! By “semantic”, I mean that the meaning of the data is encoded alongside the data in the graph, in the form of the ontology. A knowledge graph is self-descriptive, or, simply put, it provides a single place to find the data and understand what it’s all about.
The point of reading isn’t to memorize, and it’s certainly not to critique. It’s to absorb and filter with an open mind — to find the right thing at the right time so that you can improve and update your existing model of reality rather than mold whatever you’re reading to fit into it as it is.
