关于语义网:我可以说RDF Schema(RDFS)是RDF的本体吗?

Can I say RDF Schema (RDFS) is a ontology of RDF?

我对RDF和RDF Schema(RDFS)有点困惑。我读过一些文档,其中提到rdfs是为RDF定义词汇。

基于这个定义,我可以说RDFS是像OWL或Dublin Core这样的本体之一吗?

模式是一种本体,是的。

但是,RDFS是一种架构语言,例如OWL,而不是本体,例如Dublin Core,SKOS或Good Relationships。

模式语言(或本体语言)用于编写本体,它们本身不是本体。


我想说RDFS实际上是一个本体。但这在很大程度上取决于您对概念本体的理解。

我喜欢(Studer et al。,Knowledge engineering:Principles and Methods,1998):

的定义

An ontology is a formal, explicit specification of a shared
conceptualization. Conceptualization refers to an abstract model of
some phenomenon in the world by having identified the relevant
concepts of that phenomenon. Explicit means that the type of concepts
used, and the constraints on their use are explicitly defined. [...]
Formal refers to the fact that the ontology should be
machine-readable. Shared reflects the notion that an ontology captures
consensual knowledge, that is, it is not private of some individual,
but accepted by a group.

在这种理解下,RDFS是一种本体,而与RDFS通常用于定义其他本体的事实无关。 RDFS中描述的现象是类,属性及其关系。
