【摘要】 为了检查语义Web中的知识的正确性,提出了一种利用已有知识库检查语义 Web下本体中知识正确性的方法。先将本体中的知识解析并处理成三元组的集合,然后对于常识知识,利用常识知识库 WordNet,将WordNet里面的词汇对应成本体中的三元组,通过 WordNet提供的上谓词知识,检查本体中继承关系的正确性。对于领域知识,通过加入相应的领域知识库,在不同知识库上封装一个统一的知识获取接口来达到。提出的方法同时支持语义Web下最为常用的本体表示语言———RDF(resource description framework),DAML(DARPA agentmarkup language)和OWL(Web ontology language)。以该方法为基础实现了原型系统,该系统可以将本体中可能存在的错误知识提醒给用户。最后,对该方法的时间复杂度进行了分析,证实了该方法的实用性。更多还原

【Abstract】 To check the knowledge correctness in the Semantic web, a method of checking it by using the existing knowledge bases was provided. The general knowledge hierarchy structures were checked by using WordNet and the hypernym relations. The domain knowledge was checked by adding domain knowledge base. The domain knowledge base was accessed uniformly by implementing an interface. Using this interface, the domain knowledge correctness was checked. Three popular ontology languages in Semantic web as RDF (Resource Description Framework), DAML (DARPA Agent Markup Language) and OWL (Web Ontology Language), were supported in this method. Finally, the time complexity of this method was also analyzed.更多还原
