An Interactive Circular Visual Analytic Tool For Visualization Of Web Data

Visual analytics on frequent 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 co-occurring items and/or events 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 from the web. It uses an orientation free, circular layout to show frequent patterns. Moreover, we provide users with interactive feature to explicitly show connections among related frequent patterns. Experimental results show the effectiveness of our icVAT, especially in collaborative environments, for visual analytics of frequent patterns from web data.
