We have evaluated our proposal through a case study. Note
that there are several ways of performing an evaluation [36]:
from a validation before the approach has been transferred to
practice until the evaluation in a real context with real users.
This section deals with a validation of our approach before its
implementation in a real system. This type of validation suffers
from predictions and some degree of uncertainty. However, it
is the more suitable for an emerging approach where we aim to
check it before spending any effort in their implementation in a
practical setting. Next, we describe how guidelines previously
defined for any data-analysis system can be used in the
specification of our case study. As case study, we continue
with the development of a system for visualizing
archaeological information, describing how problems identified
in Section 3 are solved with guidelines proposed.
