Freebase data in Google Knowledge graph

[Vishnu]

Does Google Knowledge graph derive its birthplace data from Freebase? If so, How is Knowledge graph showing the birth place of Obama as Honolulu, HI where as the freebase shows it as Honolulu. Screenshots below:

I think you are misunderstanding what the knowledge graph is.  There is an entity: /m/02mjmr .  Freebase has some facts (triples) about it.  namely: 

/m/02mjmr -> /type/object/name -> "Barack Obama"

/m/02mjmr -> /type/object/type -> /people/person

/m/02mjmr -> /people/person/place_of_birth -> /m/02hrh0_

Then there are some other facts (triples) in the db:
/m/02hrh0_ -> /type/object/name -> "Honolulu"

/m/02hrh0_ -> /location/location/containedby -> /m/03gh4

/m/03gh4 -> /type/object/name -> "Hawaii"

/m/03gh4 -> /location/administrative_division/iso_3166_2_code -> US_HI

The Freebase.com UI is just a way of visualising the knowledge graph that shows /type/object/name instead of showing machine ids (assuming that the entity has a name in the database).

Yeah, I understand that. I was trying to figure out how the google UI is rendering the HI part in Honolulu, HI. For example in case of Abraham Lincoln, the death place shows up as Washington, DC and not as Washington, DC United States. For places in other countries they show the place, country information. May be it treats places in US differently than places in other countries
