如何在 Protege 中添加匿名个人? [英] How can I add anonymous individuals in Protege?

问题描述

我想使用空白节点在 Protege 中添加一条语句.例如，如果我将其表示为 Turtle RDF，它将是 类似:

<预><代码>[rdf:type rdf:Statement ;#这个匿名资源是一个声明...rdf:subject ex:Paul ;#...与主题保罗rdf:predicate ex:running ;#...谓词运行rdf:object "10miles" ;#...和对象10英里"例如:hasPeriodStart "2018-04-09T10:00:00"^^xsd:dateTime ;例如:hasPeriodEnd "2018-04-09T12:00:00"^^xsd:dateTime ;].

有没有办法在 Protege 中做类似的事情(不用创建具有 IRI 的命名个人)?

解决方案

Protege 不支持空白节点.实现类似目标的一种方法是为空白节点分配一个临时/单独的命名空间.我会给你一个例子来说明我的意思.假设我有以下海龟语法(我省略了前缀以保持简短)，

:jane :firstname "Jane";:lastname "Doe";:contactInfo [:phonenumber "011 739 4751";:email "[e-mail]"] .

然后

[:phonenumber "011 739 4751";:电子邮件[e-mail]"]

是一个空白节点.这可以使用空白节点 _:janeContactInfo 重写，如下所示:

:jane :firstname "Jane";:lastname "Doe";: 联系信息 _:janeContactInfo ._:janeContactInfo :phonenumber "011 739 4751";:电子邮件[e-mail]".

这可以用曼彻斯特语法表示(这是 Protege 中使用的语法):

ObjectProperty:contactInfo数据属性:名字数据属性:姓氏数据属性:电话号码数据属性:电子邮件个人:简事实:例如:名字，简"，例如:姓氏，母鹿"，例如:contactInfo，_janeContactInfo个人:_janeContactInfo事实:例如:电话号码，011 739 4751"例如:电子邮件，[e-mail]"

如果需要，您可以将 janeContactInfo 个人放在临时/单独的命名空间中.

I want to add a statement in Protege using a blank node. For example, if I expressed it as a Turtle RDF it would be something like:

[
  rdf:type rdf:Statement ;   #this anonymous resource is a Statement... 
  rdf:subject ex:Paul ;      #...with subject Paul
  rdf:predicate ex:running ; #...predicate running
  rdf:object "10miles" ;     #...and object "10miles"
  ex:hasPeriodStart "2018-04-09T10:00:00"^^xsd:dateTime ;
  ex:hasPeriodEnd "2018-04-09T12:00:00"^^xsd:dateTime ;
].

Is there a way of doing something similar in Protege (without creating a named individual with an IRI)?

解决方案

Protege does not support blank nodes. One way to achieve something similar is assign a temporary/separate namespace for your blank nodes. I will give you an example of what I mean. Assume I have the following turtle syntax (I left prefixes out to keep this short),

:jane :firstname   "Jane";
      :lastname    "Doe";
      :contactInfo [:phonenumber "011 739 4751";
                    :email       "[e-mail]"] .

then

[:phonenumber "011 739 4751";
 :email       "[e-mail]"] 

is a blank node. This can be rewritten using a blank node _:janeContactInfo as follows:

:jane :firstname   "Jane";
      :lastname    "Doe";
      : contactInfo _:janeContactInfo .

 _:janeContactInfo :phonenumber "011 739 4751";
                   :email       "[e-mail]" .

This can be represented in Manchester syntax (this is the syntax used in Protege) as:

ObjectProperty: contactInfo 
DataProperty: firstname
DataProperty: lastname
DataProperty: phonenumber
DataProperty: email

Individual: jane
Facts:
  ex:firstname, "Jane",
  ex:lastname, "Doe", 
  ex:contactInfo, _janeContactInfo

Individual: _janeContactInfo
Facts:
   ex:phonenumber, "011 739 4751"
   ex:email, "[e-mail]"  

The janeContactInfo individual you can place in a temporary/separate namespace if you want.
