| 摘 要： | 传统GIS中,文本常常被作为非空间信息而被忽视。而在实际应用中,很多有关空间位置的描述都是以文本途径来体现的。文本方式已经成为人们表达和接受空间信息的主要方式之一。地名是文本中最常见的空间信息表达内容。提出了一种基于文本地名自动识别的空间信息检索新方法,从自然语言形态的文本数据中实现地名的自动识别,并将识别的地名与空间数据进行关联显示,实现文本中地名信息的空间定位与显示。

| Abstract: | In traditional GIS,text originally usually is regarded as a non-space information document.But in fact,much space position information is discribed by text.Text has been one of the most common ways to transmit space information.Geographical name is one of the most familiar space information expressions.A new mthod of spatial information retrieval based on geographical name automatic recognition was put forward,by which geographical name was able to be automatic recognized and connected with spatial data. |
