Obtain /common/topic/description in Freebase MQL

问题

Good day,

how can I obtain the topic text description in Freebase? For example, I ask MQL query about Chernobyl disaster:

[{
  "type": "/common/topic",
  "description": null,
  "mid": "/m/07q37w"
}]

but obtain null description. At the same time I can see non-null description at Freebase page: http://www.freebase.com/m/07q37w

回答1:

/common/topic/description is a pseudo-property which is not accessible through MQL. You can use the Topic API as follows:

https://www.googleapis.com/freebase/v1/topic/m/07q37w?filter=/common/topic/description
