[英]what makes an OWL class anonymous?
I am reading a tutorial that says that this is an anonymous OWL class: 我正在阅读一个教程,说这是一个匿名的OWL类:
<owl:Class rdf:ID="Reptile">
<rdfs:subClassOf rdf:resource="#Animal”/>
<rdfs:subClassOf rdf:resource="#OxygenUser”/>
</owl :Class>
I know what an anonymous class is in Java. 我知道Java中是什么匿名类。 What makes this class anonymous in OWL? 是什么使该类在OWL中匿名? Is it anonymous because it does not have an RDFS:label statement like this: <rdfs:label>Reptile</rdfs:label>
? 因为它没有这样的RDFS:label语句,所以它是匿名的: <rdfs:label>Reptile</rdfs:label>
吗?
OWL anonymous classes are classes without a name/identifier (URI). OWL匿名类是没有名称/标识符(URI)的类。 Usually it's an OWL class expression such as eats some Grass
or Male and Female
. 通常是OWL类的表达,例如eats some Grass
或Male and Female
。 You use such expression in combination with named classes to create axioms. 您可以将此类表达式与命名类结合使用来创建公理。
Example of equivalent classes axioms using both named an anonymous classes (comments are shown by the #
symbol): 同时使用两个匿名类的等效类公理的示例(注释由#
符号显示):
# Named class (got a dereferencable URI)
Class: <http://www.example.org/Man>
# Named Class
Class: <http://www.example.org/Woman>
# Named class
Class: <http://www.example.org/Human>
# The named class Human is equivalent
# to the anonymous class (class expression) Man or Woman
EquivalentTo: <http://www.example.org/Man> or <http://www.example.org/Woman>
Do you have a source URL for the tutorial? 您有本教程的源URL吗? The example you quote does not contain any anonymous classes, so if that's a direct quote from the tutorial, it's giving out wrong information. 您引用的示例不包含任何匿名类,因此,如果这是教程中的直接引用,则会给出错误的信息。
