Motivation
Semantic Web applications
Search and navigation related issues Difficult construction of queries and ambiguity
Open ended and exploratory tasks
Complex and hard to use search interfaces
Insufficiency of classical faceted browsers
Suitability of visual approachesJanuary 21, 2008SOFSEM 2008, High Tatras, Slovakia
Personalized faceted and visual browsing

Faceted browsing challenges
January 21, 2008SOFSEM 2008, High Tatras, Slovakia
Managing information overload
Too many facets (complex information spaces)
Too many restrictions (large information
spaces)
Still too many search results
Hard to understand instance details
Advanced exploratory tasks
Faceted browser enhancements
January 21, 2008SOFSEM 2008, High Tatras, Slovakia
Refresh facet state
Log user action with semantics
Generate output
Annotate search results
Create and executedatabase query
Retrieve search resultsfrom the database
Generate the resultingbrowsing state
[update facets andrestrictions]
[update search results]
Adapt search results
Adapt facets and restrictions
Recommend facets and restrictions
Generate dynamic facets
[insufficient facets]
[facets are suitable]
Annotate facets and restrictions
Facet adaptation, annotation, recommendation

Relevance and user models
January 21, 2008SOFSEM 2008, High Tatras, Slovakia
Automatic acquisition from user behavior
User characteristics (long-term and short-
term)
In-session behavior
Global trends and popularity
Similar users and social relations
Conclusions (1)
January 21, 2008SOFSEM 2008, High Tatras, Slovakia
Evaluation with multiple domain ontologies
Scientific publications (mapekus.fiit.stuba.sk)
Digital photographs
Prototype implementation
Factic + ClusterNavigator/Clusterer
Java, Sesame, OWL + Prefuse, MySQL
Conclusions (2)
Integrated faceted and visual navigation
Personalization improves user experience
Future work
Handling multiple/multi-domain ontologies
Leveraging social networks for clustering,
navigation and visualization
