Multilevel Browsing of Folksonomy-Based Digital Collections

This paper describes how to extend the usual one-level tag selection navigation paradigm in folksonomy-based digital collections to a multilevel browsing one, according to which it is possible to incrementally narrow down the set of selected objects in a collection by sequentially adding more and more filtering tags. For this purpose, we present a browsing strategy based on finite automata. Also, we provide some experimental results concerning the application of the approach in Clavy, a system for managing digital collections with reconfigurable structures in digital humanities and educational settings.
