一种本体驱动的地理空间事件相关信息自动检索方法

An Automated Retrieval Method of Geo-spatial Event Information Based on Ontology

区别于传统的地理信息检索仅利用关键词进行匹配和查询的机制,以地理空间事件为纽带,提出一种由本体驱动的、与该地理空间事件相关的信息自动检索方法,实现用户仅仅需要了解地理空间事件发生的基本信息就可以从海量地理信息数据库中智能地提取与该地理空间事件相关的信息,并提供检索的个性化支持,以便用户主动、自动检索这些信息,简化用户获取信息的过程,减少因用户对信息组织方式、软件应用模式不了解造成的繁琐操作,提高检索效率。

An automated retrieval method of geographic event information is proposed.It is based on ontology instead of the words key in traditional geographic information retrieval to make match and inquire The geographic event is regarded as the tie in the method.Therefore,users only need to know the elementary information of geographic event and can extract intellectually the information associated with geographic event from a large spatial information database with personalized support.So,the retrieval information can be made by users automatically with simplified information access,information organization and applied model of software.And finally,the retrieval efficiency can be enhanced.
