The ‘Public’ row includes sampled results using just what the DCE returned via searches in public sources. The ‘Dimensions’ row indicates results returned by manually using the keys that generated hits in the ‘Public’ row to search Dimensions full-text articles. The ‘Both’ row combines all unique publications from each of the other two rows. Precision values are calculated using the values in the ‘Relevant Publications’ and ‘Total Publications’ Columns.
