中文简介: | 语义网广泛使用以SHOIQ描述逻辑为基础的OWL DL本体语言来形式化其资源。在本文中,我们提出了一个决策过程,该过程扩展了概念公理中角色的传递闭包,这是多个应用领域所需的一个特征。在设计这样一个决策过程时,我们必须处理的最具挑战性的问题是表示无限非树形模型,这与SHOIQ本体不同。为了解决这个问题,我们引入了一种新的阻塞条件来表征可能具有无限非树形部分的模型。 |
课程简介: | The Semantic Web makes an extensive use of the OWL DL ontology language, underlied by the SHOIQ description logic, to formalize its resources. In this paper, we propose a decision procedure for this logic extended with the transitive closure of roles in concept axioms, a feature needed in several application domains. The most challenging issue we have to deal with when designing such a decision procedure is to represent infinitely non-tree-shaped models, which are different from those of SHOIQ ontologies. To address this issue, we introduce a new blocking condition for characterizing models which may have an infinite non-tree-shaped part. |
