孕灾环境本体构建中的基础逻辑关系研究
Study on foundational logical relations for constructing ontology of disaster-pregnant environment
应急决策的目的是处理灾害后果, 突发事件的孕灾环境直接影响着灾害后果. 基于本体的孕灾环境形式化建模对于应急决策起到了辅助作用. 当前OWL语言中的基础关系is-a, 在描述孕灾环境中存在一些不足. 本文针对这些不足,提出三种总分关系作为基础关系, 这三种基础关系既可以有效地描述孕灾系统中要素间的整体部分关系, 又可以描述要素之间的相对位置关系. 基于三种基础关系, 本文提出构建孕灾环境本体模型的方法, 并以吉林石化水污染事件为例, 构建了一个元模型. 推理能力是本体方法的优势, 在文章的最后以实例比较了基于三个基础关系复合推理和描述逻辑的相关推理方法, 发现了复合关系推理的优势.
The purpose of emergency decision is to deal with the impact of disasters, which is decided by the disaster-formative environments (HE). Ontology-based formal model for HE has played an important role in the progress of decisions. However, the foundational relation of OWL, namely is-a, lacks ability in modeling the disaster-pregnant environment. This paper proposed three foundational relations based on mereotopology aiming at this problem. They are not only effective in describing the mereology relations among the elements of disaster-pregnant environment, but also can depict the relative spatial relations among them. Moreover, an ontology model of the disaster-pregnant environment is proposed based on the three foundational relations. And then a meta model is constructed taking a pollution case as an example. For reasoning is one of the most important advantages of ontology method, in the end, we compare the compound reasoning algorithm based on the above three relations with the algorithm based on description logics through an example, and find the advantage of compound reasoning.
