【摘要】 提出一种基于语义Web技术的动态交通信息的采集和发布系统。采用SVG和Ajax编程模式,在浏览器上图形界面完成动态交通信息和地图的显示、查询、搜索和规划。在交通监测中,针对路口监测系统的不足,提出一种分布于行驶车辆上的交通监测多Agent系统。采用本体语言OWL对有关概念及其相互关系进行描述,方便了Agent间基于语义的信息查询,从而可以构建开放、异构的交通信息系统。在JADE平台基础上进行开发,实现了Agent内的描述逻辑本体模型、OWL为内容的Agent通信以及符合SPARQL标准的信息查询。更多还原

【Abstract】 A transportation information gathering and publishing system,which is based on semantic web techniques,was proposed.By the use of SVG and Ajax,the dynamic transportation information can be displayed,queried,searched and planned through the browser.A Multi-Agent System,which is distributed among moving vehicles,was proposed for transportation monitoring.Ontology was written in OWL to describe the transportation monitoring concepts and the relationship between them,so to facilitate semantic information queries between Agents.On top of it,an open and heterogeneous transportation information system can be constructed.Agent system was built on the base of JADE platform.The developed Agent has an inside ontology model based on description logic,and its communication is based on OWL.The information inquiries comply with SPARQL.更多还原
