针对战场态势时空数据的中文查询技术研究

Chinese Query Technology of Spatio-Temporal Data for Battlefield Situation

战场态势时空数据引擎是基于时空数据库技术实现的,面向战场时空数据查询的战场态势辅助分析系统。针对时空数据库查询语言的复杂性,设计了战场态势时空数据引擎的中文查询系统,研究了中文查询任务到时空查询语句的映射过程,设计了时空查询词库,研究了分词算法,查询文法以及STQL生成方法。通过原型系统验证了中文查询技术的可行性,提高了时空数据库查询的可用性和易用性。

The spatio-temporal data engine of battlefield situation is based on the spatio-temporal database technology.It is assisted analysis system for battlefield situation spatio-temporal data query.For complexity of the spatio-temporal database query language,study on Chinese query system for battlefield situation spatio-temporal data,Chinese query task to the mapping process of the spatio-temporal query,spatio-temporal query thesaurus,segmentation algorithms,query grammar and STQL generation method.The prototype system verifies the Chinese query technical feasibility.The technology improves the ease of use of spatio-temporal database.
