Abstract

Phonetic transcriptions of Chinese characters association coding and spelling keyboard.Phonetic transcriptions of Chinese characters association coding is to adopt the Chinese phonetic alphabet to add the complete coding that associational word is distinguished to national standard I and II Chinese character set, is that consonant letter with the easiest associational word is as distinguish yard.Accomplishing does not have repeated code, and most of Chinese characters only need add a letter, and minority adds two letters just can distinguish whole phonetically similar words, and mean code length has only 2.7 in the Two bors d's oeuveres scheme, and it conveniently is easy to learn and use.Spelling keyboard then is to utilize in the Chinese phonetic alphabet combination of each simple or compound vowel of a Chinese syllable to get in touch a kind of keyboard arrangement of realizing Chinese phonetic alphabet Two bors d's oeuveres mode on normal standard keyboard, can provide a kind of input mode fast for Chinese characters in computer input and communication.

Description

Phonetic transcriptions of Chinese characters association coding and spelling keyboard

The invention belongs to a kind of Chinese characters in computer input method, can promote computer technology to China and play a driving role, be particularly suitable for universal education, change aspects such as ways of writing and telegraph communication.

Computing machine is promoted in China, must solve this basic problem of computing machine imported in Chinese character.Because the Chinese-character stroke complexity, quantity is big, and encode Chinese characters for computer problem Qi Jin And is solved preferably.That in general adopts now has character shape coding and two kinds of schemes of Pinyin coding.

Adopt shape code scheme, often too many because of radical of Chinese character quantity, the many usefulness of key that must not differ during with QWERTY keyboard cause repeated code, will add artificial regulation when distinguishing again, so that make a code book become awkward " book from heaven " of recognizing difficult note.

Though also there are many people to propose to use the coding of phonetic plan, because the Chinese character phonetically similar word is a lot, be to distinguish phonetically similar word, normal employing adds tone mark and adds serial number etc. again, has so both increased the complicacy of operating, and is difficult for memory again, is difficult for the quick touch system of realization.

The data of the existing coding situation of reflection has:

1. " PC World " increases number of the edition, 1984.7.

2. Chinese information processing international symposium collection of thesis, 1983.10.

At these shortcomings of existing coding, the present invention proposes a kind of encoding scheme of phonetic band association distinguish yard of Chinese character.

Characteristics of the present invention are: the consonant letter that phonetically similar word is adopted associational word is as distinguish yard, and its specific implementation principle is:

In syllable in the phonetically similar word a most frequently used word do not add distinguish yard, for example in the phonetically similar word of ma, " horse " word is the most frequently used, so the coding of " horse " is exactly ma, distinguishes letter.

2. other word in the phonetically similar word adopts the initial consonant of another word in the easiest associational word as distinguishing letter, for example the associational word of " mother " word is " mother ", so mother's coding is exactly mam, the associational word of " fiber crops " is " burlap ", so the associational word of " fiber crops " is exactly " burlap ", so the coding of " fiber crops " is exactly mab, the associational word of " scolding " is " swearing at people ", so the coding of scolding is exactly mar.

3. do not have the Chinese character of suitable associational word then to extract consonant information from font, for example most metal names are made distinguish yard with j and jn, and the other word of most wooden words is made distinguish yard with m or mw.

For utilizing common QWERTY keyboard to do the Chinese character input, also comprise a kind of keyboard configuration scheme of initial and final double-spelling among the present invention.In this allocation plan, each realizes consonant, vowel with 26 keys.

Accompanying drawing 1 is the arrangenent diagram of spelling keyboard, and its design feature is:

1. remove SH in the initial consonant and replace with U, CH replaces with V, and outside ZH replaced with I, other added that with former key position A, E, O have three simple or compound vowel of a Chinese syllable of zero initial, totally 26 keys.

2. simple or compound vowel of a Chinese syllable is also only used 26 keys, wherein has 7 for multiplexing, and promptly how a key can not cause ambiguity with ， Dan And.Indicated the frequency that each simple or compound vowel of a Chinese syllable uses among the figure.

3. the distribution of final key position is to be core with a, e, u, i, o, and each compound vowel is all at its adjacent side, and middle row arranges all vowel followed by a nasal consonants, and next row's middle part is the compound vowel of u, ü, and last row is with a → e → u → i → its single vowel of o series arrangement and compound vowel.This keys arrangement has significantly rationality, and note is recognized easily, easily operation.

The mean code length of the code book spelling of national standard I and II Chinese character being made with above-mentioned association coding method is 4.37, if adopt Two bors d's oeuveres, calculating then by frequency, mean code length is about 2.7.

With existing other Hanzi coding scheme relatively, this coding has following advantage:

1. based on the Chinese phonetic alphabet, meet that country popularizes Beijing pronunciation and the policy of the Chinese phonetic alphabet, mass foundation is wide.Association's sign indicating number is easily learned easily note, when realizing on micro computer screen prompt is arranged, and almost need not learning and memory and can operate the computer the input Chinese character for the people of the meeting Chinese phonetic alphabet, in use is familiar with easily, also realizes touch system easily.

2. further also realize easily writing, mean code length can be compressed to below 1.5 like this with the phrase input and with associational word.

3. keyboard layout of the present invention has regular preferably, is easy to learn and use.

Realization of the present invention is very simple, concrete way is to inject a floppy disk on the IBM-PC micro computer of an expansion internal memory or other compatible, can realize encode Chinese characters for computer input of the present invention, have on the machine of similar functions, need only revise a little also and can realize easily software at other.

Claims

1, a kind of Chinese characters in computer input method, its coding is made of the Chinese phonetic alphabet and phonetically similar word distinguish yard, it is characterized in that adopting the consonant letter of associational word as distinguish yard.

2, Chinese character input method according to claim 1 is characterized in that word the most frequently used in phonetically similar word additional zone demal not, the equal additional zone demal of other word.

3, Chinese character input method according to claim 1 and 2, it is characterized in that this distinguish yard by one, two Chinese Pin Yin pseudonym letters constitute at the most.

4, a kind of spelling keyboard for computing machine input usefulness, it is based on general english keyboard.Each is realized with 26 keys to it is characterized by consonant, vowel.

5, spelling keyboard according to claim 4, it is characterized by simple or compound vowel of a Chinese syllable is core with a, e, u, i, o, compound vowel, vowel followed by a nasal consonant is arranged by rule.

6, according to claim 4 or 5 described spelling keyboards, it is characterized by in the initial consonant except that SH with U replace, CH with V replace, ZH replaces with I, other all uses former key position.
