ships. Conceptual domain ontology is a systematic representation of
knowledge domain; in this work on the knowledge basis about place
names.
There is strong motivation to build the place name ontology because place
name is complex already after its definition, and demand interdisciplinary
approach. The scope of the place name ontology is defined by the area of
knowledge the ontology will cover connecting different disciplines. The
place name conceptual ontology is the human readable ontology while the
OWL ontology is machine readable.
In this work, the scope of the place name ontology is defined as place
names of the Earth surface topographic features of a scale 1:200 000 or
greater. It will include topographic features named in bigger scales
topographic maps (e.g. 1:200 000 or greater). That scope is developed
considering EuroGeoNames and Croatian examples.
5.1 Relationships rules
To define place name ontology, relationships between objects should be
defined (Horridge 2009, Kovacs at al. 2006). There are many relationships
that can be defined among place name ontology objects. Here are defined
some of them. Relationships are presented by OWL properties. There are
object and data type properties as two main types of properties in OWL.
Object properties are relationships between two objects. There are
functional, inverse functional, transitive, symmetrical, antisymmetric,
reflexive and irreflexive relationships. Data type properties are
relationships between objects and data values. There is also annotation
property that can be used to add descriptive information to classes and
objects.
