Now that we’ve covered the origins of knowledge graphs, it’s time to dig into their basic attributes. Essentially, a knowledge graph maps the relationships between objects (data) and provides information that helps humans and machines understand what the data actually means. A knowledge graph is data plus metadata (or semantic information) linked in a graph.
So you have a knowledge graph that is mapping the relationships between different components of a system, maybe it's a telecom network in the example you had. Then you are also incorporating a digital twin which I think is effectively the web agent. (Transcribed)
