Semantic-Based Navigation in Open Spaces 293
A demonstration application of OntoViews is publicly available in the domain of digital
libraries (museums) as MuseoSuomi 6 . Figure 10-19 shows the user interface of Onto-
Views, which copies the typical faceted browser layout with facets on the left and content
on the right. Search results are presented in groups corresponding to the last used facet.
The detailed instance view (see Figure 10-20) shows instance attributes at the top, followed
by a list of faceted categories to which the instance belongs. Recommended links to related
instances are shown on the right.
Figure 10-20. Example of the OntoViews GUI for presentation of instance details with Instance
attributes (top), other facet categories (center) and related instances (right).
Furthermore, OntoViews has a mobile user interface, which retains the functionality of the
original desktop interface albeit with minimal screen size.
Link generation is based on predicates in the form p(subjectURI, targetURI, explanation),
which succeed when two resources (subjectURI, targetURI) should be linked together
with label explanation. Individual rules/predicates are processed by the Ontodella service
for link generation.
