Weighted Faceted Browsing

Screenshot of the Weighted Faceted Browser instatiated for the domain of visualisation in the context of VizBoardUsually a selection in a Faceted Browser means all or nothing − between this there are no other options.

Artur Werstler, a student supervised by Martin Voigt and me, analysed how Faceted Browsing and weights could be combined. This was done with respect to both: weights in the data and weighted query expressions. A prototype he developed in the context of the visualisation workbench VizBoard was now presented by means of a short paper on the EICS 2012. It shows how weighting parts of a query and faceted browsing can be combined consistently in a single user interface. Besides using weights for sorting multiple results, also filtering may be influenced by weights given that a certain threshold has been previously defined. By using weights, it is possible to avoid filtering out good results (with respect to most criteria) too early − only because some item did not match the very first restricted facet.

Please note that the items which can be filtered in the prototype are from the visualisation domain as well. So, this specific instance of a WFB is a visualisation of visualisations.
