使用 rdflib 打印本体中每个概念的个体
我已经用 OWL/RDF(使用 Protege)编写了本体。这个本体已经填充了每个概念的一些个体。我已经使用 rdflib 和 FuXi 包将其移植到 python 中。我可以成功解析我的本体并放入图表中。现在我唯一需要做的就是打印出每个概念的所有个体。有谁知道我该怎么做?
I have and ontology written in OWL/RDF(using Protege). This ontology has been already populated with some individuals for each concept. I have ported it in to python using rdflib and FuXi packages. And I can successfully parse my Ontology and put in a graph. Now the only thing that I need to to do is that to print out all individuals for each concept. Does anyone know how I can do that?

当您说每个概念的所有个体时,我猜您的意思是
rdf的所有资源:键入特定类
。使用rdflib
,您可以通过遍历图形轻松地做到这一点:(None,rdfType,aClass)
表示迭代图形g
的约束。通过设置您可以通过主题的任意组合来约束三元组中的任何三个元素,
谓语或宾语。在这种情况下,我们仅通过谓词 rdftype 进行约束,并且
对象
aClass
。如果您想要所有个人成员和所有类,您可以这样做:
在这种情况下,我们将对象保留为未绑定以捕获任何 OWL 类。
When you say all the individuals for each concept I guess that you mean
all the resources of rdf:type an specific class
. Withrdflib
you can easily do that by traversing the graph:(None,rdfType,aClass)
represents a constrain to iterate over the graphg
. By settingany of the three elements in the triple you constrain by any combination of subject,
predicate or object. In this case we only constrain by predicate
rdftype
andobject
aClass
.If you wanted all individuals members and all classes you could do:
In which case we leave the object unbound to capture any OWL class.
