I’m trying to write an MQL query to be executed using Freebase API’s. I would like to retrieve the topic summary and the image for the topic.

I have been able to work out the below query which will get me the images associated with the Bill Gates topic.

MQL:

[   {     '/common/topic/image' : [       {         'id' : null       }     ],     'name' : 'bill gates',     'type' : '/people/person'   } ]

Results:

[   {     '/common/topic/image' : [       {         'id' : '/guid/9202a8c04000641f8000000004fb4c01'       },       {         'id' : '/wikipedia/images/commons_id/4486276'       }     ],     'name' : 'Bill Gates',     'type' : '/people/person'   } ]

For those that may have not run into MQL in the past but are interested in playing around with it. Check out the Freebase MQL Query Editor.

UPDATE

Query that I ended up using:

[   {     '/common/topic/image' : [       {         'id' : null       }     ],     'article' : [       {         'content' : null       }     ],     'name' : 'bill gates',     'type' : '/common/topic'   } ]

These results can be combined with narphorium’s answer to retrieve the actual data:

[   {     '/common/topic/image' : [       {         'id' : '/guid/9202a8c04000641f8000000004fb4c01'       },       {         'id' : '/wikipedia/images/commons_id/4486276'       }     ],     'article' : [       {         'content' : null       },       {         'content' : '/guid/9202a8c04000641f800000000903535d'       }     ],     'name' : 'Bill Gates',     'type' : '/common/topic'   } ]

  1. The images and topic summaries are stored separately in the content store and are accessible via another web service API.

    For example, Bill Gates’ image can be accessed like this:

    http://www.freebase.com/api/trans/raw/guid/9202a8c04000641f8000000004fb4c01

    Similarly, the GUID for the topic summary can be found by replacing /common/topic/image with /common/topic/article in your query. The results can be accessed again like this:

    http://www.freebase.com/api/trans/raw/guid/9202a8c04000641f8000000008bfed35

    You can read more about the content store here.
