Querying freebase for Entity and Predicte

Question

I trying to use freebase for my project. I have been successful in getting required data using MQL queries. As a next step in the project I want to query freebase for the subject predicate object triples. For example, I want to know whether information like Person X Lives in City Y is present in the freebase. In the knowledge bases like NELL it is possible to get the predicate and the object connected to the given subject as they are stored in a graph structure.

Another question is that, Given a triple Subject Predicate Object Whether it is possible to get the type of the entities acting as Subject and Object

If I understand your question correctly, you need something like this:

[{
  "type": "/type/link",
  "source": {
    "id": "/m/035qy",
    "type": []
  },
  "master_property": "/location/location/contains",
  "target": {
    "id": "/m/08v97b",
    "type": []
  },
  "target_value": null
}]

This will return the types of the subject (source) for the predicate /location/location/contains and the types of the object (target).
