基于平面螺旋关系的领域本体存储方法研究

Reseach on Domain Ontology Storage Method Based on Flat-helix Relationship

语义网络满足了人们对下一代互联网智能化的需求,用本体描述的丰富的知识库为此奠定了基础。但随之出现如何有效存储本体知识的问题。在分析领域本体与关系数据库模式各自特点和相互联系的基础上,提出了一种新的基于平面螺旋关系的本体存储方法。它将本体知识完整地保存在一张数据表中,并通过螺旋模式联结关联项,改变了将本体知识项保存在多张数据表中的传统做法,提高了领域本体存储和查询的效率,并以机械产品领域本体为例阐述了该方法的应用。

Semantic web makes us satisfied with the intelligent feature on the next Internet, which is based on the fact of applying ontology to construct a rich knowledge library. Consequently, one important problem will arise, just how to store the ontology efficiently. this paper,propose anew method of storing ontology after analyze the relationships between domain ontology and RDS mode and their respective characters. This method will store an entire ontology into one table, and connect the related elements on helix mode. Compared with the traditional ontology storage methods, it will not store the ontology elements into several tables any more, so it improves the efficiency of retrieving and storing ontology. In the end,it demonstrate the application of this new method with the example of mechanical product ontology.
