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
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
