  • Accessing knowledge related to a template for presenting structured data.
  • Identifying the primary set of a number of entities.
  • Associating a number of labels and a number of values with a number of entities within the first set of the recognized entities.
  • Obtaining a candidate label time period.
  • Identifying a subset of a number of entities from the primary set of entities.
  • Associating a number of labels and a number of values with a number of candidate label phrases
  • Receiving a seek question.
  • Using values related to each and every candidate label time period to resolve whether or not to set off show of the structured data.

So those candidate labels is also selected, once they seem in queries to show a structured data card.

For instance, the place an entity comprises an electronic mail report, community deal with, URL, or the like, an entity is also related to a candidate label time period if the candidate label time period would go back the e-mail report, community deal with, URL, or the like when a question that comes with the candidate label time period is achieved.

The machine might affiliate a number of labels and a number of values with each and every candidate label time period.

For instance, any label phrases related to a selected entity at level is also related to a candidate label time period with which the entity is said.

Thus a label time period that used to be propagated to a selected entity from a question node is also additional propagated from the entity to a candidate label time period with which the specific entity is said.
