I need to develop a tool[s] for Knowledge and Information Visualization
.
<P>I've done an initial investigation of what's been done in information
visualization and have found that
<BR>this can be an interesting application even for visualization tools
normally used for numerical data. I'd
<BR>like to find ways to use VTK object classes for Information and
Knowledge visualization. If anybody
<BR>knows of papers or free software targeted at this area please respond.
Maybe an email thread on this
<BR>subject can created as responses to this inquiry. All that
I've come up with so far is some ideas:
<P>1) There is a relatively new area called KDD (Knowledge Discovery
in Databases) which
<BR> seems to be a systematic way of extracting
knowledge from the results of data mining using multivariate
<BR> visualization tools. VTK probably
has several such tools (including parallel coordinates and scatter plots
<BR> for example) which could be used to
build a KDD system.
<P>2) This is only a vague idea but if the information is modeled
with OOP then since VTK is object oriented
<BR> there should be some 1-1 translations
from information hierachies to vtk object hierarchies .
<P> -
One simple thing is that the units of knowledge might be simple shapes
(maybe superquadrics).
<BR>
An information tree could be built with spatial transformations on
the shapes. Each shape
<BR>
could be created in a ways so that it inherited visual attributes in a
direct correspondence
<BR>
to its inheritance of knowledge from another object class.
<P>Thanks in advance,
<BR>Dave
