User-centric Faceted Search for Semantic Portals

A paper written by Eero Hyvönen, Kim Viljanen and Osma Suominen. It was presented at the ESWC2007. It is about card-sorting, complex ontologies, semantic portals, user-centric design and fuzzy logic

Abstract

Many semantic portals use faceted browsing, where the facets are based

on the underlying indexing ontologies of the content. However, in many
cases, like in medical applications, the ontologies may be very large
and complex, and do not provide the end-user with intuitive facet
hierarchies for conceptualizing the content, for formulating queries,
and for classifying the search results.  We argue that in such cases
end-user facets should be separated from the annotation ontologies,
and show how to generalize the semantic view-based search paradigm to
take into account this fact. A user-centric card sorting method is
proposed for designing intuitive views for the end-users and a method
for mapping its facets onto the indexing ontologies and search items
is presented.  The system has been implemented in a prototype of the
semantic portal TerveSuomi.fi, a national health promotion portal in
Finland.
