I was invited to work at Google in 2013 on an internal project using their Knowledge Graph. I had just written two books on RDF/SPARQL/linked-data and at first I was taken aback by the query language used at the time. However, when I realized how well the KG scaled and how fast the queries were, I became a fan.
BTW, I think this paper is very well written. Graph queries is not an easy topic and their examples and text make the data types, syntax, and how to perform matches and aggregations easy to follow.
