网络环境下基于Jena的规则推理方法研究

Study on method of rule reasoning Jena under network environment

分析本体、本体描述语言、Jena推理机制,研究并实现基于本体推理过程的方法。对RDF本体模型的推理是重点。RDF以三元组模型描述网络资源。首先利用知识本体对应用领域建立语义模型,得到领域相关的知识结构,然后添加领域资源的RDF描述。领域知识结构和RDF描述结合在一起形成知识库,再根据RDF蕴涵规则进行有限形式的推理。建立了旅馆、饭店领域的RDF模型,并藉此模型进行推理。

It was analyzed Ontology, Ontology language and Jena reasoning system, studied on the method based on reasoning process of ontology. In this process, the key part was the reasoning of RDF ontology model. Network resource was described with triple model by RDF. First, it was built the semantic model of certain domain with ontology, and then added the semantic description rule about resources by RDF. The incorporation of ontology and RDF rule formed the knowledge base. This could support some limited inference according to RDF rules. It was implemented the RDF model of hotel and restaurant, and the reasoning was based on this model.
