OntoClock, The Difference Between Having Ontological Knowledge and Knowing It
(There are also two 2007 poster papers material available through this page as well.)
The ontologies have the knowledge indicated below (amongst many other things):
all geometrical
objects have a size.
a graph-bar has color and is a (kind of) plane.
and can be inferred
to have a size since it is a geometrical
object and
to have an area since it is a plane
which is a 2 dimensional object.
a bit more inferencing
provides area to be the value of size for 2D objects and
volume to be the value of size for 3D objects and
length [to be the value of size] for 1D objects.
((note that a 1D
object might be a highly-inflected (fractal [or fractional dimension])
curve))
(example Koch curve or Sierpinski curve)
[and one way of calculating the length of such a line (curve) is the
box dimension with sides of length r]
circle has scalar
radius
radius is a 1D geometrical object
and can be inferred : the radius of a circle has a length, a
numerically specified linear extent
To you (the reader) this circle stuff is mind-numbingly obvious, it is what you use everyday as common knowledge, it is in fact part of your cognitive finessing knowledge. To a machine where no one is home this circle stuff is news and provides a means to implement a model of human's cognitive finessing. (which includes the capability of inferring equalities-identities and similarities.)

"He's dead, Jim."*
Is this usuality? well, uh, not exactly. Let's look at what Lotfi Zadeh meant by his term, usuality.
First of all, it is NOT the same as probability.
