Abstract

We present a novel user interface for visualizing and navigating in a multimedia document collection. Domain ontology has been used to depict the background knowledge organization and map the multimedia information nodes on that knowledge map, thereby making the implicit knowledge organization in a collection explicit. The ontology is automatically created by analyzing the links in Wikipedia, and is delimited to tightly cover the information nodes in the collection. We present an abstraction of the knowledge map for creating a clear and concise view, which can be progressively ‘zoomed in’ or ‘zoomed out’ to navigate the knowledge space. We organize the graph based on mutual similarity scores between the nodes for aiding the cognitive process during navigation.
