基于内容的战场信息分发系统研究

摘要

战场信息的按需分发技术是战场信息服务的关键技术.针对目前战场信息按需共享能力不足的问题,通过分析作战用户的信息需求特点,建立了一个基于内容的信息分发系统模型,并对战场信息的元数据描述、信息需求模型的构建以及信息推荐等系统实现的关键技术进行了研究.与其他传统信息分发系统相比,基于内容的信息分发系统能更好满足海量战场信息精准、按需共享的需求.%The on-deman d dissemination of battlefield information is the key technology of battlefield information service. Aiming at the shortage of the current battlefield information on-demand sharing ability,a content-based information dissemination system model is established according to the characteristics of the information needs of operational users. In addition,the key technologies of the system are studied,such as the metadata description of battlefield information,the construction method of information demand model and information recommendation technology,etc. Compared with other traditional information dissemination systems,content-based information dissemination system can better meet the needs of massive battlefield information sharing on demand.
