How is a publication identified as a "resulting publication" for a grant?

Links between grants and publications in Dimensions are made in two ways - 

1. This information is provided by the grant Funder to us directly, and simply incorporated into Dimensions.

2. The acknowledgment sections of full text publications are analysed, and grant codes are identified from these. These grant codes are then matched to the Dimensions grant database, to make the link which then appears in Dimensions as “resulting publications” of a grant.
