Online Information Visualization: Automatic Mapping of Data Entities to Representation Artefacts

In order to allow Online Information Visualization of Seman- tic Web data we must have a method of automatically mapping entities in the source data to representation artefacts in the target format. Online Information Visualization aims to increase the accessibility of otherwise machine-readable only data by creating a "good enough" vi- sualization quickly and simply. The system requires no user interaction and has no prior knowledge of the information domain. We present a technique which assess the characteristics of each entity in the source data and maps them to the representation artefacts deemed appropriate in the target format. Our technique is independent of the source data format and target visualization format. We provide a worked example and user evaluation of the SVG visualization of a real-life data format (BBC top 40 music chart).
