Abstract
The present invention relates to a Chinese character coding method for a computer. At present, how to solve the problems of difficult normalization, difficult standardization, low efficiency, slowness, complexity, difficult learning, etc. is the main problem existing in Chinese character coding methods. In the method, single characters and word groups are coded by utilizing the stroke of a character initial of each Chinese character and the stroke of a character tail of each Chinese character or the character radical of the character initial of each Chinese character and the character radical of the character tail of each Chinese character or by combining Chinese character pinyin. The specific coding mode comprises: two strokes are respectively taken from the character initial and the character tail to determine stroke order codes according to the total four strokes, or the character radical code of the character initial and the character radical code of the character tail are priorly utilized as the stroke order codes to form the codes of the single characters or the codes of the word groups by utilizing the stroke order codes or combining the Chinese character pinyin. The present invention has the characteristics of definite characteristics, single rule, small memory quantity, low coincident code rate, etc.
Description
The present invention is a kind of computer Chinese character key-board input method of utilizing radical, two-stroke arrangement, phonetic to combine.
At present the computer Chinese character key-board input method has multiple scheme, still, the subject matter of its existence be the standard that how to solve encode Chinese characters for computer, standard, efficient, fast, problem such as simple, Yi Xue.So-called standard is meant that coding rule is clear and definite, the problem that does not exist or seldom exist fork to separate; Standard is meant that coding rule should be the most common and the clearest and the most definite according to some, for some feature of Chinese characters that most of people can understand are formulated; Efficiently be embodied on the code length unsuitable long, theoretically, express with existing conventional characters, distinguish each Chinese character and do not have repeated code, at least need three characters, accomplish this point and in fact be difficult to strictness,, just should be considered as efficiently if reach triple bond or be less than triple bond one word as its average input efficiency of an encoding scheme; Be to reduce repeated code fast as far as possible, improve input speed; Easy to learn is exactly to want coding rule few as far as possible, and memory capacitance is few and be convenient to association, and reduces the irregular processing of special case and special circumstances as far as possible.Should still need to study better coding method in order to overcome the above problems simultaneously.
In the known coded scheme, people have utilized the various features of Chinese character as code element, mainly comprise: phonetic, tone, radical, radical phonetic, stroke, stroke position, stroke number, stroke arrangement etc.Yet, be not only as a kind of outstanding coding method and will go to seek new or more features of Chinese character in order is used for coding, and the more important thing is and need research to adopt which kind of or which feature more to meet the optimization principles of coding.In fact the Hanzi features that can be used to encode is limited after all, and is not necessarily suited for coding according to some feature of optimization principles, though as the tone standard, a lot of people grasp bad; The single stroke unavoidable efficient that is used to encode is on the low side; Stroke position, stroke number are used for coding and use comparison difficulty etc.If consider like this, practical code element type is perhaps only several.
Except that code element, in every type of coding method, also there is the difference on concrete rule or the implementation detail.When coding method occurs in a large number and is gradually improved, the main foundation of the branch of the difference coding method quality often on this rule or the details.Although diverse ways has his own strong points,, people expect to have a kind of outstanding coding method always can hold each strength, also overcomes simultaneously its deficiency, this in addition can become the long-term target of pursuing of people.
In Chinese patent literature, proposed a kind of Chinese character first and last stroke code that utilizes in the application number 91106400.1 and carried out Methods for Coding, had many advantages in conjunction with phonetic, as the process of having avoided Chinese character to split, need not define and remember a large amount of radicals, coding rule simply, clearly wait.But owing to only adopt the head and the tail stroke code to combine with phonetic, its repetition rate of coding is than higher, and estimation can reach about 20%, and adopts five code lengths, and efficient is lower.
In Chinese patent literature, the another kind of coding method that utilizes radical, five stroke combination and phonetic initial consonant to combine has been proposed in the application number 94103068.1, though it is less to have radical, and standard, standard, advantages such as code length is short, still, owing to adopt three graphemic codes, still the process that can not avoid Chinese character to split especially adopts the 3rd, the 4th stroke combined code to increase certain difficulty to input; In addition, only adopt 26 English alphabets,, cause repeated code easily, therefore, need reduce efficient with the conversion of V key during the input phrase though import more conveniently as coded character set.
The present invention wishes to reach the simplification coding rule by seeking and utilizing some basic and clear and definite features of Chinese character and these combination of features to carry out individual character and phrase coding, increases the standard degree, reduces the memory composition, improves the purpose of code efficiency.
The present invention is achieved in that
At first the basic stroke of Chinese character is divided into point (comprise and carry, press down), horizontal, vertical, cast aside, five kinds of strokes of folding (comprising other strokes beyond preceding four), and the arrangement in twos of five kinds of strokes is assigned on English alphabet keys a～y, stroke is arranged corresponding character appellation " stroke permutation code "; From Chinese characters in common use radical, radicals by which characters are arranged in traditional Chinese dictionaries, select the part radical as " coding radical " again, and be assigned on numerical key 0～9 and the English alphabet keys a～y coding pairing character appellation of radical " package code "; In addition, consider that coding needs, and is defined as complement code with alphabetical z; Numeral 0-9 and English alphabet a-z are simultaneously by appellation " coded character ".According to above-mentioned definition, utilize package code, the stroke permutation code, complement code constitutes Hanzi font code, constitute the phonetic sign indicating number according to phonetic transcriptions of Chinese characters again, graphemic code or combine with the phonetic sign indicating number and to constitute Chinese character and phrase coding then, it is characterized in that and to be defined as one-to-one relationship respectively between coding radical and stroke arrangement and the coded character, principle according to " radical is preferential; after stroke is; worth choosing benefit ", choose package code or stroke permutation code and suffix according to the lettering pen preface from prefix and choose package code or stroke permutation code or two graphemic codes of complement code formation, appellation " a sequence characteristics sign indicating number ", choose the first two letter of phonetic transcriptions of Chinese characters or comprise that the first two letter of pinyin simplified letter or phonetic alphabet add two phonetic sign indicating numbers of space formation, appellation " phonetic characteristic code ", sequence characteristics sign indicating number combines with phonetic characteristic code and constitutes single encode Chinese characters for computer, and a sequence characteristics sign indicating number of phrase first word combines with a sequence characteristics sign indicating number of phrase end word and constitutes phrase and encode.
When determining prefix, suffix radical and prefix, suffix stroke, utilized the notion of a preface, a preface has clear and definite definition and is familiar with by people in most cases, therefore the definition of prefix, suffix radical or prefix, suffix stroke also has definition, is grasped by people easily.Utilize prefix, suffix to be feature, simplified process and method that Chinese character splits, and prefix, suffix feature are outstanding, have realized regular simple, code clear and definite purpose requirement.
As the specific embodiments of said method, can take following steps:
1, with the basic stroke of Chinese character, return into five types as point, horizontal, vertical, left-falling stroke, folding, right-falling stroke, hook etc., be defined as follows:
1. Dian (
), point comprises and carries, presses down;
2. one, horizontal stroke;
3. Shu is perpendicular;
4. Pie casts aside;
5. (
亅
), folding comprises preceding four kinds of strokes other stroke in addition, as perpendicular folding, left-falling stroke folding, horizontal hook, lifting-hook, cross break hook, horizontal crotch etc.
Like this, all Chinese character basic strokes can be representative by above five classes, as the basic stroke type of this encoding scheme.
2, aforementioned five class basic strokes are arranged according to the order of sequence in twos, are assigned on 25 English alphabet keys, are defined as follows:
Q: Dian Dian w: Dian one e: Dian Shu r: Dian Pie t: Dian
Y: a Dian u: i one by one: a Shu o: a Pie p a:
A: Shu Dian s: Shu one d: Shu Shu f: Shu Pie g: Shu
H: Pie Dian j: Pie one k: Pie Shu l: Pie Pie m: Pie
X: Shu Dian c: one v: Shu b: Pie n:
English alphabet " z " usefulness not in definition will be as complement code in the coding.According to above-mentioned definition, 25 English alphabets and stroke are arranged and have been formed one-to-one relationship, are the stroke permutation code, and they are arranged on keyboard in order, easily memory.
3, select 35 Chinese radicals or radicals by which characters are arranged in traditional Chinese dictionaries as coding characteristic, these radicals or radicals by which characters are arranged in traditional Chinese dictionaries are the coding radical, and it is assigned on digital 0-9 and 25 English alphabet keys except that z, are defined as follows:
1: wood 2: fire 3: soil 4: Jin 5: Rui
6: day 7: the moon 8: mountain 9: stone 0: field
Q: Cannibals w: The-Fan e: youngster r: sub-t: very little
Y: worm u: horse i: ten o: p again: several
A: mouthful s: Xin d: Lv f: order g: towel
H: Quan j: eight k: people l: standing grain m: king
X: Yan c: v: b: women n: big
More than be by letter tactic on keyboard.Part radical or radicals by which characters are arranged in traditional Chinese dictionaries and above-mentioned radical are closely similar, will be as with the code word root, as: say, the scholar, lonely,
Only used a small amount of radical according to above-mentioned definition, and formed one-to-one relationship between coding radical and its code, these codes are package code.
4. single Chinese character is encoded, its method is:
(1) arranges according to the coding radical or the stroke of prefix and suffix, preferential according to radical, principle after stroke is is determined first and final characteristic code, promptly then preferentially get package code as prefix coee for coding during radical when prefix, the stroke permutation code of then getting the first stroke and second during for the coding radical is as prefix coee; Equally, when suffix is then preferentially got package code as the suffix sign indicating number for coding during radical, the stroke permutation code of then getting pen second from the bottom and last during for the coding radical is as the suffix sign indicating number; Prefix, suffix sign indicating number promptly constitute two sequence characteristics sign indicating numbers of individual character, for example:
A sequence characteristics sign indicating number of " people " is " one ", " ", i.e. " cp ";
A sequence characteristics sign indicating number of " Chinese " is " Rui ", " again ", i.e. " 5o ";
A sequence characteristics sign indicating number of " word " is " Dian Dian ", " son ", i.e. " qr ";
A sequence characteristics sign indicating number of " root " is " wood ", " Pie Dian ", i.e. " lh ";
A sequence characteristics sign indicating number of " society " is " Dian ", " soil ", i.e. " x3 ";
Meet independency principle when (2) getting the package code of prefix, suffix, promptly be surrounded with the coding radical of a closed curve with prefix or suffix, wherein do not comprise other stroke, and this curve does not intersect with other stroke yet, prefix as " always " word can not be as " soil ", its sequence characteristics sign indicating number should be " Shu ", " Pie ", i.e. " im ".
When (3) getting prefix, suffix sequence characteristics sign indicating number, during for two of two of stroke less thaies or sequence characteristics sign indicating number less thaies, adopt the mode of following allonge or complement code to handle:
For the single word, prefix coee is the repetition stroke permutation code of this stroke, and the suffix sign indicating number uses z as complement code, for example:
The prefix coee of " one " is " one by one ", and the suffix sign indicating number is " z ", and its sequence characteristics sign indicating number is " uz ".
For two words, prefix coee is package code or stroke permutation code, and the suffix sign indicating number uses z as complement code, for example:
The prefix coee of " two " is " one by one ", and the suffix sign indicating number is " z ", and its sequence characteristics sign indicating number is " uz ";
The prefix coee of " people " is " people ", and the suffix sign indicating number is " z ", and its sequence characteristics sign indicating number is " kz ".
For three words, prefix coee is package code or the stroke permutation code of the first two, the suffix sign indicating number get the 3rd repetition stroke permutation code or with z as complement code, for example:
The prefix coee of " justice " is " Pie Dian ", and the suffix sign indicating number is " Dian Dian ", and its sequence characteristics sign indicating number is " hq ";
The prefix coee of " doing " is " one by one ", and the suffix sign indicating number is " Shu Shu ", and its sequence characteristics sign indicating number is " ud ";
The prefix coee of " individual " is " people ", and the suffix sign indicating number is " Shu Shu ", and its sequence characteristics sign indicating number is " kd ";
The prefix coee of " horse " is " horse ", and the suffix sign indicating number is " z ", and its sequence characteristics sign indicating number is " uz ".
For the Chinese character of coding radical representative more than three, prefix coee is a package code, and the suffix sign indicating number uses z as complement code, for example:
The prefix coee of " king " is " king ", and the suffix sign indicating number is " z ", and its sequence characteristics sign indicating number is " mz ".
For other Chinese character more than three, after prefix coee was got the coding radical, during two of residue stroke less thaies, the suffix sign indicating number be the repetition stroke permutation code at end, for example:
The prefix coee of " skill " is " Lv ", and the suffix sign indicating number is " ", and its sequence characteristics sign indicating number is " dn ".
Above regular appellation " worth choosing benefit " promptly when two of two of stroke less thaies or sequence characteristics sign indicating number less thaies, adopts the mode of allonge or complement code to handle.
Can not reuse radical or stroke feature when (4) getting prefix, suffix sequence characteristics sign indicating number, for example, after the prefix coee of " certainly " was got " Pie Shu ", the suffix sign indicating number then can not be got " order ", and its sequence characteristics sign indicating number should be " Pie Shu ", " one by one ", i.e. " ku ".
When (5) getting the phonetic sign indicating number, phonetic alphabet have been carried out following simplification and modification:
1. zh, ch, sh are replaced as one by z, c, s respectively;
2. ang, eng, ing, ong are replaced as one by g;
3. ü is replaced by u.
Owing to the phonetic sign indicating number has only been carried out a small amount of simplification and modification, so do not increase too much memory capacitance.
(6) get the front two letter of phonetic transcriptions of Chinese characters in order, when phonetic alphabet had only one, second was the space, and two codings of Gou Chenging are phonetic characteristic code like this, claim the phonetic sign indicating number again.Determine according to prefix, suffix that two sequence characteristics sign indicating numbers combine with the phonetic sign indicating number and promptly constitute four single character codes that appellation " four-stroke sequential syllable sign indicating number " is called for short " preface sound sign indicating number ".
According to the method described above, the preface sound sign indicating number of part Chinese character is exemplified below:
The preface sound sign indicating number of " people " is: " cpmi "
The preface sound sign indicating number of " Chinese " is: " 5oha "
The preface sound sign indicating number of " word " is: " qrzi "
The preface sound sign indicating number of " root " is: " lhge "
The preface sound sign indicating number of " one " is: " uzyi "
The preface sound sign indicating number of " two " is: " uzer "
The preface sound sign indicating number of " people " is: " kzre "
The preface sound sign indicating number of " doing " is: " udga "
The preface sound sign indicating number of " individual " is: " kdge "
The preface sound sign indicating number of " horse " is: " uzma "
The preface sound sign indicating number of " king " is: " mzwg "
The preface sound sign indicating number of " skill " is: " dmyi "
The preface sound sign indicating number of " always " is: " imla "
The preface sound sign indicating number of " certainly " is: " kuzi "
The preface sound sign indicating number of " society " is: " x3se "
The preface sound sign indicating number of " " is: " aaa "
5, be to get its sequence characteristics sign indicating number by general single character code method to radical word (the tone-off word that definition is arranged in the character library) its method of encoding, then, the phonetic sign indicating number partly replaces with two alphabetical zz.
6, be to choose a sequence characteristics sign indicating number of first word of phrase and a sequence characteristics sign indicating number of end word constitutes phrase coding to phrase (comprising two words and multiword phrase) its method of encoding, for example:
" people " are encoded to: " kzcp "
Being encoded to of " Chinese character ": " 5oqr "
Being encoded to of " socialism ": " x3hq "
As much as possible two words and multiword phrase be can include, code efficiency and input speed helped improving.
To above coding embodiment, what time followingly specify:
Can adopt brevity code when (1) using preface sound coding, promptly for some word can only get its all-key last, two or three as this word code, the brevity code word does not have repeated code;
(2) owing to enlarged coded character set, this coding method repetition rate of coding is lower, and great majority are two word repeated codes in the repeated code word, like this, the desirable brevity code of everyday character when determining single character code, the word that is of little use still adopts all-key, promptly four preface sound sign indicating numbers keep one yard of a word, can further reduce the repetition rate of coding;
(3) most of Chinese characters can adopt the brevity code input, improve code efficiency, and, when designing computer programs, can carry out screen and follow the trail of demonstration the brevity code word, do not need special memory.
According to short-cut method, above-mentioned part Chinese character can adopt the brevity code input, is exemplified below:
The brevity code of " people " is: " cp "
The brevity code of " Chinese " is: " 5o "
The brevity code of " word " is: " qrz "
The brevity code of " root " is: " lh "
The brevity code of " one " is: " uz "
The brevity code of " two " is: " uze "
The brevity code of " people " is: " k "
The brevity code of " justice " is: " hq "
The brevity code of " doing " is: " ud "
The brevity code of " individual " is: " kd "
The brevity code of " horse " is: " u "
The brevity code of " king " is: " m "
The brevity code of " skill " is: " dny "
The brevity code of " always " is: " im "
The brevity code of " certainly " is: " ku "
The brevity code of " society " is: " x3s "
Adopt above-mentioned coding method to mainly contain following advantage:
1. this method reduces to 60 with the font element, arranges comprising preferred 35 coding radicals and 25 kinds of strokes, and these elements have certain rules, and compare standard, standard, and quantity is few, easily memory.
2. increased coded character set, adopted 35 characters and 35 coding radicals to form one-to-one relationship, both effectively utilized the keyboard resource, reduced repeated code, made the radical code simply clear and definite again.
3. utilize a head and the tail sequence characteristics sign indicating number of Chinese character, avoided the fractionation of Chinese character, coding rule is simplified, and code taking rule can not produce fork generally speaking and separate, it is clear and definite to meet feature, the requirement that rule is single.
4. the mode that adopts brevity code to combine with all-key, promptly a word is one yard, and brevity code is got in everyday character, and the mode of all-key got in the word that is of little use, and can make the individual character repetition rate of coding drop to very low degree.And most everyday characters can be adopted brevity code input, and phrase adopts four yards inputs, have reduced the repeated code of individual character and phrase effectively, have improved code efficiency, make most of individual characters realize the mixing touch system of the following input of triple bond and individual character, phrase.
According to These characteristics, the present invention is a kind of standard, standard, simple, clear and definite coding method, have simultaneously fast, efficient, easily learn, easy-to-use advantage.
