Abstract
Tag-based browsing is a common interaction technique in business, the culture industry and many other domains. According to this technique, digital resources have a set of descriptive tags associated, which can be used to perform an exploratory search, letting users focus on interesting resources. For this purpose, a set of tags is collected sequentially, and, at each stage, the set of resources described by all the selected tags is filtered. This browsing style can be implemented using inverted indexes. However, this implementation requires a considerable amount of set operations during navigation, which can have a negative impact on user experience. In this paper we propose addressing this shortcoming by using a cache that makes it possible to identify equivalent browsing states (i.e., states yielding the same set of filtered resources), which in turn will avoid redundant computations. The technique proposed will be compared with more basic implementations using a real-world web-based collection in the field of digital humanities.

Along the paper we adopt standard set-based notation as a basic descriptive language. In particular, x ∈ Θ denotes that the element x belongs to the set Θ. Θ0 ⊆ Θ1 (respectively, Θ0 ⊂ Θ1) means that Θ0 is included in, or it is equal to (respectively, is included in, but it is not equal to) Θ1. ∪, ∩ and - denotes respectively set union, intersection and difference. {x ∈ Θ | Φ(x)} denotes the set of all the elements x in Θ satisfying the condition Φ(x). 2Θ denotes the powerset (i.e., the set of all the sets) of Θ. ∅ denotes the empty set. |Θ| denotes the cardinality (i.e., the number of elements) of Θ. ∪x∈Θ Ψ(x) (respectively, ∩x∈Θ Ψ(x)) denotes: (i) ∅ if Θ = ∅; (ii) Ψ(x) if Θ = {x}; and (iii) the union (respectively, intersection) of the sets Ψ(xi) for each element xi in Θ if |Θ| ≥ 2. Finally, Θ0→ Θ1 denotes the set of functions from Θ0 to Θ1 (if ϕ is one such function and x is an element of Θ0, then ϕ(x) denotes the value given to x by ϕ).

Thus, since information for ∅ is always cached, it is not necessary to distinguish an special case for F = ∅ when computing RF after a remove action.
