基于语义发布订阅系统的战场态势实时分发技术

随着战争形态的多样化和范围的越来越广,战场态势呈现信息量大、复杂性、无规则性、多变性。针对现有的发布/订阅系统不能支持复杂结构的态势来进行事件发布和订阅的语义匹配,提出了基于语义发布订阅系统的战场态势实时分发技术。采用本体描述战场态势的概念模型,采用RDF图表示需求方订阅条件,基于该战场态势本体设计高效的发布订阅匹配算法。实验结果表明,该技术能够支持复杂战场态势实时分发和具有较高的订阅匹配效率。

Battlefield Situation Real-time Distribution Technology Based on Semantic Publish/Subscribe System

With the wide range and diverse form of the war,the battlefield situation presents a large amount of information,complexity,no rules,and variability. The existing publish/subscribe systems cannot support the situation with complex structures to match the publish and subscribe events semantically. To solve them,this paper presents a real-time distribution technology of battlefield situation based on semantic publish/subscribe system. The concept model of battlefield situation is represented as ontologies,and the subscribe conditions are represented as RDF graphs. Then,the efficient matching algorithm is designed based on this battlefield situation ontology. Experimental results show that it can support the real-time distribution of complex battlefield situation and has high matching efficiency.
