The data exploration paradigm of faceted browsing has been applied successfully in many systems that provide access to either semantic data or more conventional databases. A general limitation is that the user can examine the results for only one query (i.e., one combination of facet value constraints) at a time. But there are many everyday tasks for which it is desirable to be able to compare the results for two or more queries or to refine several queries incrementally in parallel. In this paper, we introduce parallel faceted browsing which enables the user to construct a tree of queries and associated results whose structure captures the commonalities among the queries. The entities represented in this demonstrator are events associated with Helsinki’s role as the 2012 World Design Capital, as well as related events from other data sources that took place in Finland during the same period. Semantic Web technologies are used in the back-end for representing and reconciling those heterogeneous data sources. Several types of task have been identified in which parallel faceted browsing offers added value. Careful attention has been paid to interaction design with the goal of making this inherently more complex paradigm as intuitively understandable as normal faceted browsing.
