A scientific conference is a type of event for which the struc-tured program is generally known in advance. The Semantic Web community has setup a so-called Semantic Web dog food server that exposes structured data about the detailed program of more and more conferences and their sub-events (e.g. sessions).

This demonstrator introduces an interaction design for <i>parallel faceted browsing</i> that makes it easy for a user to construct and view the results of multiple interrelated queries. The paradigm offers general benefits for a(More)
