Summary + Conclusion
• Faceted Classification avoids …– too many predefined classes– empty classes
• Faceted Browsing means exploration– Personal search path– Little domain knowledge required
• Set of characteristics• Detailed comparison of 12 browsers• Facets are not flat
– Advanced widgets to reflect structure• Most generic approaches miss this
– Many views, little specific widgets

Outlook
• Use …– For Filtering (Databases / Semantic Web / Softwarestructures)– As Prerequisite to Visualization• Advanced Visual Query Construction– Complex navigation modes: Set-based Browsing/Pivoting– Facet values ORed
• Meta-Faceted Browser– http://polowinski.de/work/facetedbrowsing
