A shape-based visual interface for text retrieval

We describe a shape-based visual interface for information retrieval and interactive exploration that exploits shape recognition. Our exploratory system uses procedurally generated shapes coupled with an underlying text-retrieval engine. A visual interface based on 3D shapes (glyphs) enhances traditional text-based queries and summarization. Our interface lets users visualize multidimensional relationships among documents and perceive more information than with conventional text-based interfaces. It promotes information overview and drill-down in support of analysis. Before describing our visual interface and application, we introduce information retrieval within the context of data mining and provide a brief overview of procedural shape generation. We then describe our current system and give a few relevant examples. Finally, we offer some ideas for future enhancements and direction.
