1	Interfaces to a Statistical Knowledge Network Interface 2003 March 14, 2003 Salt Lake City Gary Marchionini University of North Carolina at Chapel Hill march@ils.unc.edu
2	Context NSF Digital Government Program Cooperative research grant 2002-2005 UNC-CH EIA 0131824 UMD-CP EIA 0129978 BLS, EIA, NASS, SSA, Census, NCHS User interfaces as the glue in a SKN Audience: Novice/casual end users See http://www.ils.unc.edu/govstat
3	Statistical Knowledge Network Information resources Tools for collecting, finding, using, and managing statistical information People and processes that gather, analyze, manage, and report statistical information Concept-based rather than file-based.

6	The Challenges Massive volumes of federal, state, and local statistical information=> need for good filtering support. Federal, state, and local statistical providers use a variety of standards, formats, terminology, and practices for collecting and disseminating statistics=> need for metadata interoperation. The full population includes people with diverse user needs, experiences, and technological platforms=> need for multiple, alternative solutions. The level of statistical/numerical literacy in the population is generally low=> need for online help and support.
7	Multi-faceted Attack User Needs: Scenarios Metadata Information architecture Manual (both agency and user centered) Automatic Vocabulary & Concepts Help
8	Manual IA: How to Slice and Dice?
9	Automatic Slicing and Dicing Automatic classification Crawl website(s) Create reduced term-document matrix Cluster (various) Label clusters Apply labels and documents to different views (slices/dices) Evaluate
10	Vocabulary & Concepts Statistical Ontology (see also Hovy) Concepts mapped to metadata Interactive Statistical Glossary Simple and extended textual definitions Graphical explanations Animated explanations Links to experts and community Context dependent, core set of terms, hover or click mechanisms, video or Flash explanations for specific numbers (in text or in tables)
11	Index Concept: CPI Example
12	Index Concept: Octane Rating Example
13	New Approaches to Online Help in Public Access Information Systems Multilayered Interfaces Levels Modules Integrated Initial Guidance Sticky notes Animated and Video Demos Recorded with voice
14	Sticky Notes
15	Animated Demos Create script (much easier for specific activities than for concepts) Record vignette (5-15 seconds) Add effects and voice over Package and link
16	Link to other services FAQ Glossary (where applicable) Email experts at agencies Post to community Chat with shared browser
17	Example Interactive Interfaces Relation Browsers (Simple and Advanced) Interactive Maps (Spatial Browsers) Free Link Browsers (Network Browsers)
18	Relation Browser Legacy
19	Multiple Iterations Several usability studies Multiple database upgrades Separate results and exploration to preserve screen real estate Implementations for several kinds of data
