一种符合ISO14651语义的藏文排序实现方法

本文介绍了一种实现藏文字典序排序的方法,它针对藏文“大字丁字符集”编码方案。通过引入有(无)前加基字符的概念,它把待排序的藏字预处理为有(无)前加基字符、前加字符、基字(基字符或者字丁)、后加字符、再后加字符串后,再行比较,从而避免拆分字丁。本实现方法符合ISO/IEC14651标准语义。

A Method for Ordering Tibetan Text in Arccord with ISO 14651

This thesis discusses the machine ordering of Tibetan words on the basis of linear characters, which means any pre-composed forms or vertical stack can be processed as a single Tibetan character. Our method is to divide Tibetan words into two types: with or without pre-consonant character. And by defining base characters without pre-consonants and base characters with pre-consonants, we convert the Tibetan words into all kinds of strings like base characters without pre-consonants, base characters with pre-consonants, pre-consonant characters, base characters, post-consonant characters, ppost-consonant characters. Then compare all the defined units with their weight and acquire results. The method is according with the semantic of ISO/IEC 14651.
