Information seeking scenarios. We use three information seeking scenarios to study navigability of recommendation networks. The objective in point-to-point navigation is to find a single goal item. For berrypicking, we cluster the networks and set the goal of finding any one item in four predetermined clusters (shown in gray). For information foraging, the goal is to find multiple items in a predetermined cluster. These scenarios cover the rediscovery and serendipitous discovery points of Toms’s ways of information retrieval [1]
