without demanding manual updating on the source
code. The ArchCollect software current version
presents a significant improvement to the interaction
pattern and to the monitored application markup
language implementation, when compared to the
previous version (Lima, 2003).
A direct interaction acquisition mechanism can
generate fast and accurate n-dimensional
information cube used as a collaborative filtering
algorithm input, to establish some patterns based on
usage, layout, content and performance focus. None
of the related works collect the element page
directly, what compromises the accuracy, making
future preprocessing necessary.
The acquisition mechanism compatibility to the
Netscape© browser is not complete. It cannot
capture the end of the session in Netscape©
browsers, because these assume that regions b and c
form a single region. For this browser type only the
interactions in region b are captured.
A possible limitation, not only to the ArchCollect
acquisition mechanism, but to every Web usage
mining tool that collects data from the user, is the
risk of the user disabling the monitoring in his/her
browser. That is valid for tools that use cookies, Java
applets or any plugin to be installed.
The collecting mechanism can be extended to
collect sounds and facial images produced by users,
and also to collect defined interactions as XML
elements/metatags from distributed systems.
Finally, it is necessary to extend the acquisition
mechanism compatibility, which is so far limited to
the Internet Explorer© and Netscape© browsers.
