How to use Google Knowledge Graph API

问题:

In what useful way can I use Google Knowledge Graph API at the moment?

Let's say I have the MID for 1990 FIFA World Cup, which is /m/014nm_

and I make this request:

GET https://kgsearch.googleapis.com/v1/entities:search?ids=%2Fm%2F014nm_&key={MY_API_KEY}

I'll get something like this http://pastebin.com/M1fgj7Ew

Now how can I use that information in a meaningful way? Just a description and a wikipedia link is not that comprehensive. How can I find out what other entities are linked to this one in the graph?

If I search on Google for 1990 World Cup, I'll get a Knowledge Graph card like this one

Here I can clearly see useful information like Best Player and Goals scored, so Google has to have other entities linked to 1990 FIFA World Cup in the knowledge graph.

Google does not expose additional facts from its knowledge graph, so you'd have to get data from an outside source. To my knowledge there are no complete sources that are available. There are incomplete ones, such as Wikidata, DBPedia, and loads of the Freebase dump data.

Youtube has a Freebase Topic API, you can search for videos and channels by Knowledge Graph id.
