Patent ID: 7861164

Claim:
A method of delineating a Chinese PINYIN form with few symbols comprising steps of: (a) dividing elementary PINYIN symbols into coding groups included in a lookup table; (b) associating each coding group with a coding symbol; (c) differentiating elements within said coding group with a coding symbol or a string of coding symbols; (d) converting the elementary symbols within said Chinese PINYIN form sequentially into said coding symbol or said string of coding symbols; and (e) rendering said coding symbol within a string of coding symbols achieved by said converting method sequentially to a unique PINYIN element; whereby said Chinese PINYIN form is delineated by few coding symbols of said coding symbols, and the string of said delineated coding symbols is uniquely correlated to the original Chinese PINYIN form; and wherein the lookup table contains PINYIN symbols in either Romania form or classic Chinese form of 20 elementary initial consonants, 6 elementary vowels and 4 tones, and the elementary symbols have been divided into 10 coding-groups or coding set by means of: each set contains one double coding consonant item, one single coding consonant item and an additional coding vowel or tone item; each set is associated with a coding symbol or a digit; an individual PINYIN element is coded by its coding symbol except for that: said double coding consonant item is coded by the double coding symbol; said additional coding vowel item is coded by its coding symbol plus a different coding symbol when said additional coding vowel appears at the initial position of a PINYIN form, whereby said Chinese PINYIN symbol in either Romania style or classic style is converted to a coding symbol or a string of coding symbols, which is uniquely correlated to its original PINYIN symbol during the sequential delineating process.
