Steve,
While we haven't calculated the stats out at NCSU recently, I do have
some carefully configured stats from Jan - April 2007 that could serve
as representative. These numbers should have done a more complete job of
eliminating bot activity (bots *love* facets, even when you try to
exclude them) than the numbers found in the presentation, although the
overall outcome is similar. The percentage here is percent of facet usage.
Topic: 28.5%
LCC: 24.3%
Format: 14.4%
Library: 9.2%
New: 6.4%
Genre: 5.1%
Author: 3.9%
Region: 2.9%
Language: 2.1%
Era: 1.8%
Availability: 1.2%
These numbers were calculated at a time when all facets showed at least
5 values by default (we've since closed some of the facets by default in
the interface). Obviously, the placement of the facets and whether or
not values are show probably impact usage. For the order the facets
where presented at the time these stats were taken, I'd use the chart in
the powerpoint; we've also since re-ordered our facets.
We might have more data to share if you have other specific questions.
