      At first and at base it signifies experience, but much more can be
expressed about second-hand experience (things one reads about) and abstract
logical things such as mathematical objects and hypothetical worlds - even
about ontologies.    (01)

    I have mentioned on several occasions that to "understand" any set if
symbols the way that humans do it is necessary for those symbols to be
"grounded" in perception and action.   Ultimately, robotic perception and
action primitives will be needed to supplement the non-procedural elements
that are used in most ontologies; these procedural functions will be called
by functions within the ontology, much as arithmetic functions can be
called, but with robotic effects.  That will provide the necessary grounding
in the real world that will allow computers to grasp the meanings of terms
in  a manner that is **functionally equivalent** to that of humans, though
the internal representation will not much resemble the connections of the
brain.
   Until that is possible, for a lot of very practical purposes, the
"grounding" of ontologies will be provided by humans who understand the
meanings of the symbols the way human can, and use those symbols
appropriately in their programs.  Even now, even computers without sensors
or effectors do have some capability of "grounding", as for example, to
determine the temperature of some location, to go on the web and find the
weather report; or, if an appropriate link is provided, to warn motorists of
congestion on certain highways.  With the internet, computers can affect the
world by transmitting data elsewhere, and perhaps get a response that can be
interpreted within the logical structure of the ontology used.  Linking
language to virtual worlds can substitute to some extent for real-world
experience, but with the caveat that a virtual world may not conform to
real-world properties.   The ability to search the web for text and observe
what words can be in what relation to others provides additional constraints
on what the words mean, and whether the internal representation conforms to
actual real-world usage.  One theory of meaning (google:  "procedural
semantics" + Woods) says, in paraphrase,  that "the meaning of an object is
to be able to recognize it when observed; the meaning of an action is to
recognize it and when possible to perform it."   In this manner, "that is a
louse" would cause the machine to expect that, when it looks in the
direction pointed to, it will observe an object conforming to the appearance
of a louse.  Additional levels of meaning for computers, as with people,
will be available when they (and we) know a lot more about objects (e.g.
behavior, stability, structure) than just how to recognize it.    (02)
