via the LVQ network. If the output is not the desired one, then the process
is iterated using the connected nodes. Finally, the obtained knowledge is
stored in the form of connected weights. Meanwhile, users form queries of
a specific problem via the friendly interface, and then get the desired answer
from the database system.
The process of knowledge discovery, defined in the above model, starts
with the construction of an initial LVQ network. An initial LVQ network
is constructed to form and represent the initial set of goals. These goals are
expanded in the database exploration process so that knowledge discovery
will be conducted in a more content-controllable manner. Given the initial
LVQ network ...
