摘要:

现今，计算机网络被广泛应用于生活的方方面面，而从海量的信息中搜寻出人们所需要的还存在诸多问题，于是产生了本体的概念。而本体的查询和推理是基于本体的应用中重要的组成部分，研究的目的是为了使知识得以充分表达并且对信息的查询更加精确、完备。首先介绍了本体的概念并建立本体模型，然后用本体杳询语言SPARQL对已有模型进行查询并用SWRL对模型进行语义规则的扩充；最后介绍了Jena，并对本体模型进行推理，由此获得了更多知识。结论就足，在利用SPARQL和Jena进行查询与推理的过程中，推理将提高查询能力，而规则是提高推理能力的关键

Abstract:

Nowadays, computer network is widely used in various aspects of life. But searching for what people need from the mass infor- mation has a lot of questions. Consequently, the concept of ontology has appeared. And then ontology querying and inference is the im- portant component of the application based on ontology. The purposes of this research are to make the knowledge to the fullest expression and querying the information more accurate and complete. Firstly,introduced the concept of ontology and constructed an ontology model. Then used ontology query language, SPARQL, to query the existed model. And also used SWRL to extend the semantic rules. Finally,in- troduced Jena with which obtained more knowledge by reasoning on the model. Thus concluded,in the process of querying and inference with SPARQL and Jena,inference could develop the ability of querying, and the rules were the key to increase the power of inference
