The Thunderstone Categorizer was originally created to support our
web search engine at search.thunderstone.com, and
to categorize the websites into a hierarchy. It has many other uses
beyond categorizing websites, and can be trained on existing
documents.
Categories can be added on an as needed basis, and
the categorizer can be run either in a supervised, or unsupervised
mode. eWeek labs looked at a number of categorizers, including the
Thunderstone Categorizer in the July 15, 2002 issue. You can find a
link to the eWeek article in the News Section of our
website. For more details on the Categorizer please contact
us.
When printing Vortex variables, sometimes the value is HTML-escaped,
and sometimes not. HTML escapement occurs only when HTML mode is on,
ie. when any of these conditions occur:
The Vortex URL has no extension, or one of the extensions
.html, .htm or .wml
The output Content-Type is text/html, eg. via
an appropriate <header> statement
Thus, in most cases escapement is already on or off as appropriate
for the document (HTML vs. text).
Often it's useful to avoid escaping just one variable, rather than
change escapement for all variables. In that case <send
$var> or <fmt "%s" $var> can be
used to print the variable without escapement. The <send>
function prints every value of its argument, as-is, but does
not support embedded nuls (ASCII 0). The <fmt>
function supports full binary values, only prints the current value of
its arguments, and has a wide range of other printing options.
