Getting our head in the clouds: toward evaluation studies of
tagclouds. In *Proceedings
of the SIGCHI Conference on Human Factors in Computing Systems* (San Jose,
California, USA, April 28 - May 03, 2007). CHI '07. ACM Press, New York, NY,
995-998. DOI=


Tagclouds are visual presentations of a set of words, typically a set of
"tags" selected by some rationale, in which attributes of the text such as
size, weight, or color are used to represent features, such as frequency, of
the associated terms. This note describes two studies to evaluate the
effectiveness of differently constructed tagclouds for the various tasks
they can be used to support, including searching, browsing, impression
formation and recognition. Based on these studies, we propose a paradigm for
evaluating tagclouds and ultimately guidelines for tagcloud construction.
