10.7.1 Factic: Adaptive Faceted Semantic Browser
We devised a method for personalized faceted navigation (Tvarožek & Bieliková, Personalized
Faceted Navigation for Multimedia Collections, 2007) and implemented a prototype
faceted browser Factic (Tvarožek & Bieliková, Personalized Faceted Navigation in the Semantic
Web, 2007). Factic is an adaptive faceted semantic browser for OWL which supports
semiautomatic configuration of the underlying faceted classification based on the
used domain ontology.
The GUI of Factic copies the standard faceted browser layout with facets on the left,
current query at the top and search results in the center (see Figure 10-12). Users can navigate
the available facet hierarchy via view-based search and examine the details of individual
instances, for which the respective properties are displayed recursively (see Figure
10-18).
Figure 10-18. Example of the Factic GUI for presentation of instance details. Main attributes are
shown at the top, other attributes are recursively expanded (bottom).
