RE: Question about ontology

 

Further, it's said a FullBottle results from "pouring"? Is it a
different thing if I pour first through a filter into the bottle? Or how
about if I collect the liquid into the bottle through a wholly different
process, not pouring anything at all --- is that not a "FullBottle"
anymore? 

This is not a rhetorical question - it arises when something
is categorically defined with reference to a process or action performed
to create it.

PS You are not 'in' a marriage. In fact nothing
is "in" a marriage that I know of. Sure a marriage "has" a Wife and
"has" a Husband, and you "are" a husband. Why not just use those words?


Marriage:Obama has:this Husband:Barack_Obama
Marriage:Obama has:this
Wife:Michelle_Obama
Husband:Barack_Obama is:this Person:Barack_Obama


Can this possibly be improved, that is, made more clear to the AVERAGE
person? How would other ontologies indicate the same smenatic content --
do they pass the "shared, intuitive understanding" test?

adjectives and prepositions is seriously, deeply flawed -- such an
ontology makes assertions such as yours ("no difference...(between)... a
relation/predicate and (its) object") almost reasonable!

problem is that there IS a difference. Objects are nouns. Subjects are
nouns. But predicates can NOT be nouns; nouns can NOT be predicates.
Rather, common nouns connote types of things: they are but labels for
distinguishing generic identities. Nouns are not candidates for
predicates!

cased in the noun hierarchy and then lower-cased in the property
hierarchy -- golly how pregnant with meaning that first letter is made
to be!

over-interpret natural language grammar (nor physical appearance for
that matter) when it comes to semantics. I can easily juggle around with
adjectives, nouns and verbs and turn them into each other without
changing the meaning of the sentence. Natural language grammar is
superficial/superimposed structure for a large part. As much as that I
can say that I am *IN* a marriage (which I am), I can say that some
marriage relates me to my wife. Also, there is no fundamental difference
between a relation/predicate on the one hand and an object on the other.
They are just different perspectives of the same. A marriage is equally
a relation as it is an object. We tend to take them apart, but for
superficial reasons (natural language grammar, or mathematics).
Reification is no exception, it's the rule. Don't we say that we take
*PART* in a relation?

bottle" as the relation in this example. It relates "empty bottle" and
"liquid". The pouring is the context responsible for defining that
relation. In case we can't express contextuality, I would settle for
seeing it as the third component of the relation. This makes sense (in
this example), because you need "pouring" *FIRST* before you can have
full bottles.

*BEING IN SOMETHING* and *TAKING APART IN SOMETHING* is superficial, I
do not say that such distinction is always irrelevant. But, in case I
would feel that this distinction is relevant, I should think about what
makes the difference. This context (the differentiator), though, is
*SPECIFIC*, it's not fundamental. This even holds for the physical
context.
