  1. Presentation to FedStats, March 30, 2001 User Interfaces for DGRC Steven Feiner Surabhan Temiyabutr Department of Computer Science Columbia University New York, NY 10027 feiner@cs.columbia.edu Supported by NSF Grant EIA-9876739

  2. Background: Team Approach • User Interfaces • Y1 Hatzivassiloglou, Sandhaus • Y2 Feiner, Temiyabutr • Databases • Y1 Gravano, Singla • Y2 Ross, Zaman, Ding • Automatic Inter-Agency Ontologies • Y1–2 Klavans, Whitman

  3. Background: Y2 Research • User Interfaces • Identify and address problem areas • Develop query interface and link with ontology • Databases • Complete existing aggregation prototype • Develop main memory techniques for speed • Automatic Inter-Agency Ontologies • Incorporate into SENSUS • Add web crawler to extend coverage • Develop mechanisms to merge definitions

  4. User Interface Approach • Redesign Y1 UI • Heuristic analysis • Prototypes • Informal experiments • Formal experiments and feedback

  5. Redesign: Starting Point

  6. Redesign: Next Steps • Problem areas • Query • Alleviate “peep-hole” confusion of walking menu • Results • May interface with Marchionini et al. table browser • Ontology • Explore presentation strategies: layout, distortion viewing (e.g., fisheye), filtering, . . .

  7. Redesign: Next Steps • Problem areas • History • Support reuse and modification of previous queries • Metainformation • Determine utility and presentation approaches • Integration • Maintain consistency/linkage across displays • Leverage ontology

  8. Experiments • Design/perform/analyze formal user experiments • Feed back experimental results to UI design
