• The exploratory search systems designers need to pay attention to maintain the coherence and intuitiveness of the interaction model. The inspirations can lead to a profusion of functionalities that can result in an interface that is confusing to the users



We started to experiment a novel protocol for evaluating exploratory search systems:

• The topic explored is chosen by each participant at the beginning of the search session.

• The participants' memory is used as a system efficiency metric.

• The users' intents are analyzed a-posteriori thanks to search session screencasts.
