What's not to like about this excerpt: (02)
"In its simplest form, this is a structure that is also supported by
technologies, such as _RDF_ and _OWL_. However, a semantic model
includes the following semantic extensions that support an improved
computer interpretation of such sentences and an improved computerized
verification of semantic correctness: (03)
* Each kind of relation has a modeled definition. Those semantic
definitions of the relation type includes the definition of the required
kinds of roles and the allowed kinds of players of such roles. For
example, the relation type <is located in> requires a physical object in
a 'locator' role and another physical object in a 'located' role. (04)
* Each individual thing is classified by a kind of thing, because the
meaning of a relation between individual things can only be interpreted
correctly when each related individual thing is classified, as well as
the roles they play and the relation they have. (05)
* The kinds of things are defined by at least a relation with their
supertype kinds of things, thus forming a taxonomy of concepts (a
specialization hierarchy, also called a subtype-supertype hierarchy).
This is necessary for the interpretation of the meaning of the
classifiers (city, tower, and 'is located in', as well as 'locator' and
'located'). (06)
This results in a universal basic semantic data structure for the
expression of facts about individual things." (07)
