基于地名首字母模糊查询的关键技术研究

根据地名信息的特点,提出一种基于地名首字母的模糊查询方法。采用Access数据库,结合微软自带的字库实现了地名首字母的提取与入库,特别是解决了多音字在首字母提取及入库时的处理,并提供了一种文件批量输入的方法,实现了基于地名首字母的模糊查询。设计开发的地名查询系统,使用简单,效率也得到了极大的提高,可以获取对应的地理位置,为后继GIS系统开发提供方便。

Research of Key Technology for Query Methods Based on Palcename Initial

This paper find a new fuzzy query method based on palcename initial according to the recent palcename query methods used in GIS, design the database according to the character of toponym geographic information.Realized the distill and input database for palcename initial, especially solved the difficulty of polyphone, and also gave a input way for file.The palcename query system that this paper designed used simply, it not only could upgrade efficiency, but also could give the other geographic information.In fact, it will bring much more convenient for GIS in the future.
