The model for adaptive facet navigation in open digital collections

The authors propose a formal model to describe an adaptive facet navigation for a special type of digital collections consisting of independent objects unequivocally defined by their attributes. A facet table represents the structure of collection. Navigation suggests a stepwise building of facet formula of the request, while the relevant subset of facet table is represented in the user interface. The proposed formal model is used to produce an executive model with visual interface adapting to the current status of collection and scenario of access to the collection's objects defined by user.
