基于概念代数的本体演化

Ontology Evolution Based on Concept Algebra

针对本体模型的维护和演化问题,将代数格与概念格相结合,定义概念代数,提出基于概念代数的本体演化3层结构,包括原子概念层、原子概念关系层、应用层。分析概念代数与本体表示语言OWL之间的对应关系。在应用层中,利用概念代数根据应用的需要在原本体模型基础上构建面向应用的概念,并维护原有本体模型。实例证明了该方法的有效性。

Aiming at the maintenance and evolvement of ontology model, this paper combines algebraic lattice with concept lattice, defines concept algebra, and proposes 3-layers architecture of ontology evolution, which consists of atomic concept level, atomic concept relations level, and application level. The corresponding relations between concept algebra and Ontology Web Language（OWL） are analyzed. In the application level, application-oriented concept can be builded according to the applied requirement, and existing ontology model can be maintained. An example is designed to validate the method.
