Visual analytics on frequent web usage patterns aims to help users to (i) analyze the data so as to discover implicit, previously unknown and potentially useful information in the form of collections of frequently visited web pages in a single session and to (ii) visually represent the discovered knowledge so as to gain insight about the data.
In this paper, we propose an interactive visual analytics tool (icVAT) for frequent pattern mining. It uses an orientation free, circular layout to show frequent patterns. Moreover, we provide users with interactive feature to explicitly show connections between superset and subsets of sets of visited web pages. Experimental results show the effectiveness of our icVAT for visual analytics of frequent patterns about web data.
