I'm cc-ing to SEEK-KR-SMS because of general interest.

Indeed there is something inherently problematic with the
visualization of ontologies that are more than just labeled directed
graphs (a la RDF or OWL lite) but that contain formulas/axioms.

Of course you can visualize an OWL statement such as 
	owl employee eqv person and worksfor some employeer.
(here I use what we call the "Sparrow syntax" of OWL; Shawn and I are
working on some Sparrow tools -- more soon ;-)

But the problem is that when you visualize a formula, what you
effectively do is visualize the parse tree of the formula, but not its 
"meaning" in terms of the facts (say of the form C1--R-->C2). So I
think there is some utility in visualizing formulas in graphs, but it
has to be taken with a grain of salt.

To improve the situation one needs a reasoning that can derive some
"consequences graph" from a set of axioms, most notably the class
hierarchy. Then that one would be visualized. 

Visualizing axioms is not bad, but doesn't tell the whole story.

I think that for description logic formulas the textual representation
is still one that should be there as well.

Of course the "ontology graphs" are more suitably visualized as graphs 
(while the jury is till out for "ontology formulas"; for those, as
mentioned we should often just visualize some or all of the "graph

Serguei and Kai:

I think both of you aim at similar things for SEEK and GEON,

In GEON we're looking at two tools for ontology entry: Codex from PSU
and the Cmap tools...

time to compare notes =B-)
