摘要
目前,GIS地名查询一般都是以输入准确中文作为查询条件,但在实际应用中,有时用户说不清楚地名的准确中文;有时用户由于中文输入法操作不熟练而在中文输入上浪费了许多时间。针对这两个问题,提出了一种基于汉字模糊音的地名查询方法,即以汉字拼音首字母作为该汉字的模糊音,给定查询条件时以模糊音代替原来中文输入,实现地名查询。设计了实现该方法的两个可行方案,并作了分析比较。采用地名模糊音方案实现了该方法。该方法对于增强地名查询功能、提高地名查询效率具有一定的实际意义。
Usually, we need to type in exact Chinese as inquiring term. In fact, we sometimes can＇ t ensure the exact Chinese or waste time on typing in Chinese. So this paper presented a new approach of geographical name inquiring based on fuzzy Bopomofo. It took Chinese first Bopomofo as fuzzy Bopomofo and accordingly took geographical name fuzzy Bopomofo as inquiring term. In this paper, we designed two achieving schemes, compared with each other, and selected the second to come true. The new approach had certain actual meanings to enhance the geographical name retrieval function and efficiency.
