The confusing thing is that this lecture was delivered on Sep. 19, 2022, but it seems from the diagram above that over the last ten years knowledge graph has made no progress. The diagram is still what I was shown when I was a student in 2015 or 2016.
Since I cannot get a hold of this professor, I googled knowledge graph progress pictures but found that no single one mentioned any big events after 2012.
What happened over the last decade to knowledge graph? Any big events?
