领域本体构建与关系推理

Domain Ontology Construction and Relational Reasoning

在快速发展的信息化时代,各领域数据增长飞快,但由于数据来源多、结构松散、关系复杂多样,数据共享存在一定的困难。本体的出现促进了各领域的信息共享,以军事领域为例,构建军事事件本体、武器装备本体和战场环境本体模型。然后建立属性关系、时空关系和语义关系来表达领域信息关联关系,综合考虑军事领域多要素,清晰地表达军事事件、武器装备、战场环境之间的复杂关系;最后,将语义网规则语言(Semantic Web Rule Language,SWRL)特点与本体相结合,对本体进行语义推理,挖掘领域内存在的隐含关系,为实现各领域的信息共享和智能检索提供基础。

In the rapidly developing information era,data in various fields grows rapidly,but there are certain difficulties in data sharing due to multiple data sources,loose structures,and complex and diverse relationships.The emergence of ontology promotes information sharing in various do-mains.In this paper,taking the military domain as an example,we construct ontology models of military events,weapons and equipment ontology and battlefield environment ontology.Then,we es-tablish attribute relations,spatio-temporal relations and semantic relations to express the association relations of domain information,and synthesize multiple elements in the military domain to clearly express the complex relationships among military events,weaponry and battlefield environment.Fi-nally,we combine SWRL rules with ontologies,and perform semantic reasoning on ontologies to ex-plore the implicit relationships existing in the domain,so as to provide a basis for information sharing and intelligent retrieval in each domain.
