【 摘 要 】

This paper describes a node-centric technique for visualizing Resource Description Framework (RDF) graphs. Nodes of interest are discovered by searching over literals. Subgraphs for display are constructed by using the area around selected nodes. Wider views are created by sorting and displaying nodes based on the number of incoming and outgoing arcs. The visualization provides a consistent left-to-right orientation for node connectivity and the user browses by simply selecting nodes or arcs of interest. An example interaction is presented along with a discussion of the design and implementation tradeoffs. Providing an acceptable interactive response time required introducing a preprocessing step and trading space for speed by creating large cross-referenced indexes. Notes: 15 Pages
