dataCommons.org: Data Commons Knowledge Graph (DCKG)

[ElwinHuaman]

Hey all,

I was challenged last week to provide info(in rough numbers) about the Data Commons Knowledge Graph(DCKG), which was constructed by synthesizing in a single Knowledge Graph from many different data sources[1]. What I am looking for especially is to know:

- How many entities or nodes the DCKG has?, understanding that dcid (DataCommons identifier) is a unique identifier assigned to each entity in the knowledge graph, furthermore entities are represented by nodes[2].
- How many data sources the DCKG has?, because currently contains data from Wikipedia, the US Census, NOAA, FBI, etc?[3].
- How many nodes and relations the DCKG has? and How many statements it has?

• For example, the statement "Santa Clara County is contained in the State of California" is represented in the graph as two nodes: "Santa Clara County" and "California" with an edge labeled "containedInPlace" pointing from Santa Clara to California.

- What is the current size of the used vocabulary in the DCKG?, taking into account that dataCommons.org builds upon on the vocabularies defined by Schema.org[4]
- These are potential FAQs for future researchers (of course there are more)

Could you help me?

cheers,
Elwin Huaman
