RDF图Entailment [英] RDF Graph Entailment

问题描述

我刚刚阅读了关于RDF（资源描述框架）蕴含概念的内容。任何人都可以告诉我一个需要两个RDF图表的例子并解释它们。 p>感谢

解决方案

假设您有以下内容：

  ex：book1 rdf：type ex：Publication。 
例如：book2 rdf：类型例如：文章。 
  

因此，像 SELECT？s {？s rdf：type ex：Publication}这样的Sparql查询， 只会返回ex：book1

如果您添加事实（或您的数据集中包含事实的图表）：

  ex：Article rdfs：subClassOf ex：Publication 
  

如果你的sparql引擎处理引用，它应该推断出一个ex：Article也是一个ex：Publication

so SELECT？s PS：为了获得更多信息，这个例子来自于<？em>：<？em> ：将返回ex：book1 AND ex：book2

I just read about the concept of entailment for RDF (Resource Description Framework).Can anyone tell me an example of entailment for two RDF graphs and explain them a bit.

Thanks

解决方案

Suppose you have the following :

ex:book1 rdf:type ex:Publication . 
ex:book2 rdf:type ex:Article .

So a Sparql query like SELECT ?s { ?s rdf:type ex:Publication } will return only ex:book1

If you add the fact (or a graph in your data set with the fact) that states :

ex:Article rdfs:subClassOf ex:Publication

If your sparql engine processes entailments, it should deduce that a ex:Article is also a ex:Publication

so SELECT ?s { ?s rdf:type ex:Publication } would return both ex:book1 AND ex:book2

PS: for more information, the example comes from http://www.w3.org/TR/2009/WD-sparql11-entailment-20091022/
