Recall bases for three topics and three scenarios. The recall bases of Topics 28, 36, and 92 represented in ideal cumulated gain for the three scenarios: None, Doctors and Patients. For Topic 28 most of the highly relevant and fairly relevant documents were assessed to have target group Doctors. Topic 36 had the relevant documents spread fairly evenly between the Doctors and Patients target groups. Topic 92 showed no documents of any relevance grade for documents marked for target group Doctors. Thus the None and the Patients ideal gain vector coincide fully, while the cumulated gain for the Doctors scenario is very low originating from the downgraded patient documents.
