摘要: 无相关技术背景的领域专家较难直接阅读和理解OWL 2本体。为此,提出一种使用对象角色建模(ORM)可视化表达OWL 2本体的方法,并介绍一系列相应规则。通过语义等价的模型变换和扩展构造原语,使用ORM可视化表达OWL 2的构造原语、类表达式、类公理、对象特性公理、数据特性公理和键公理。实验结果表明,内置数据类型、类等价公理和对象特性的传递性公理需要对ORM进行扩展才能表达,其余OWL 2类和公理均可语义无损地转换为ORM模型。

Abstract: In order to address the problem that it is difficult to read and understand ontology expressed by OWL 2 for domain experts who have no related knowledge, this paper proposes complete mapping rules to represent OWL 2 axioms with Object Role Modeling(ORM). Based on semantic equivalent translation of models and extension of model constructions, OWL 2 primitives, class expressions, class axioms, object and data property axioms, and key axioms can be visualized by ORM directly. However, the built-in data types, class equivalent axioms, and transitivity axioms can be only visualized by expanded ORM.
Key words:
OWL 2,
fact-oriented modeling,
Object Role Modeling(ORM),
ontology visualization,
model transformation rule
