使用Jena以编程方式生成OWL类层次结构 [英] Programmatically generating OWL class hierarchy with Jena
问题描述
我想通过提供向量以编程方式使用OWL生成本体。我的目标是能够在Protégé中打开生成的OWL文件并使用Jena。
I want to programmatically generate an ontology using OWL by supplying a vector. My goal is to be able to open the produced OWL file in Protégé and make use of Jena.
输入向量
我要传递的向量:
[[层,网络层,数据链路层,物理层],[网络,计算机网络],[数据链接],[本体,本体提取] ]]。
Input Vector
The vector which i want to pass:
[[layer, network layer, data link layer, physical layer], [network, computer network], [data link], [ontology, ontology extraction]].
预期输出
输出应具有以下树状层次结构:
Expected Output
The output should have the following tree-like hierarchy structure:
layer
-network layer
-data link layer
-physical layer
network
-computer network
ontology
-ontology extraction
data link
分层结构,其中网络层
低于 layer
等等,非常重要。
The hierarchical structure, where network layer
is below layer
and so on, is significantly important.
这是我要生成的文件的示例:
This is an example of the file I want to generate:
<rdf:RDF
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
xmlns:owl="http://www.w3.org/2002/07/owl#"
xmlns:xsd="http://www.w3.org/2001/XMLSchema#"
xmlns:rdfs="http://www.w3.org/2000/01/rdf-schema#">
<owl:Class rdf:about="#network"/>
<owl:Class rdf:about="#ontology"/>
<owl:Class rdf:about="#physical_layer">
<rdfs:subClassOf>
<owl:Class rdf:about="#layer"/>
</rdfs:subClassOf>
</owl:Class>
<owl:Class rdf:about="#data_link_layer">
<rdfs:subClassOf rdf:resource="#layer"/>
</owl:Class>
<owl:Class rdf:about="#network_layer">
<rdfs:subClassOf rdf:resource="#layer"/>
</owl:Class>
<owl:Class rdf:about="#computer_network">
<rdfs:subClassOf rdf:resource="#network"/>
</owl:Class>
<owl:Class rdf:about="#ontology_extraction">
<rdfs:subClassOf rdf:resource="#ontology"/>
</owl:Class>
</rdf:RDF>
推荐答案
你的问题不是很清楚(见评论,以上)所以我要猜测你想以编程方式创建一个类层次结构。使用Jena执行此操作的大纲代码为:
Your question isn't very clear (see comment, above) so I'm going to take a guess that you want to programmatically create a class hierarchy. The outline code for doing this using Jena would be:
OntModel m = ... your model ... ;
NS = "http://your.domain/example#";
// define the various classes
OntClass layer = m.createClass( NS + "Layer" );
layer.setLabel( "layer", "en" );
OntClass networkLayer = m.createClass( NS + "NetworkLayer" );
layer.setLabel( "network layer", "en" );
// ...
// create the class hierarchy
layer.addSubClass( networkLayer );
// ...
// save the file
FileWriter out = null;
try {
out = new FileWriter( "./test.owl" );
m.write( out, "RDF/XML-ABBREV" );
}
finally {
if (out != null) {
try {out.close()) ) catch (IOException ignore) {}
}
}
