Databases Y1 Gravano, Singla Y2 Ross, Zaman, Ding

Automatic Inter-Agency Ontologies Y1–2 Klavans, Whitman

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

User Interface Approach Redesign Y1 UI

Heuristic analysis Prototypes Informal experiments

Formal experiments and feedback

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
