VAST 2008 Challenge: Introducing mini-challenges, VAST '08. IEEE Symposium on Visual Analytics Science and Technology (2008)195-196
Visual analytics experts realize that one effective way to push the
field forward and to develop metrics for measuring the
performance of various visual analytics components is to hold an
annual competition. The VAST 2008 Challenge is the third year
that such a competition was held in conjunction with the IEEE
Visual Analytics Science and Technology (VAST) symposium.
The authors restructured the contest format used in 2006 and 2007
to reduce the barriers to participation and offered four minichallenges
and a Grand Challenge. Mini Challenge participants
were to use visual analytic tools to explore one of four
heterogeneous data collections to analyze specific activities of a
fictitious, controversial movement. Questions asked in the Grand
Challenge required the participants to synthesize data from all
four data sets. In this paper we give a brief overview of the data
sets, the tasks, the participation, the judging, and the results.
