Visualizing and exploring large networked information spaces with matrix browser

This paper presents a new approach for visualizing and exploring large networked information structures which may represent, for instance, linked information resources or metadata structures such as ontologies. An interactive matrix display is used for showing relations between concepts and concept hierarchies displayed along the two axes of a matrix. The new approach also focuses on the engineering process to create these information networks. Initial user testing shows performance advantages as well as reduced visual search in comparison to conventional graph representations.
