Description

Digital union code Chinese character input method and keyboard thereof

The present invention relates to computer input method for Chinese character and keyboard thereof, particularly Chinese character digital coding input method and keyboard thereof, belong to technical field of computer information processing.

In the prior art, the ubiquitous shortcoming of Chinese character coding input method for computer is: the Hanzi component standard of divining by means of characters and formulating not in full conformity with the State Language Work Committee, the Chinese-character order of strokes standard that the code fetch order is formulated not in full conformity with the State Language Work Committee.General Chinese-character numeral encode method or the form of a stroke or a combination of strokes value of only getting stroke, and the positional information of stroke is not carried out systematic research and utilization; Perhaps continue to use font code and get the mode of radical, be difficult to solve the key position less, contradiction that Hanzi component is many, the employing of radical is not formed the method for certain rules, the standardization of radical utilization is relatively poor.The learnability and the input efficiency contradiction of general Chinese-character numeral encode method are more outstanding, and easily often code length is long, the repetition rate of coding is high in the coding method of learning, and the repeated code number of words is many on the same group.And develop rapidly along with the Internet now, the Chinese character set of Chinese platform has been finished by GB 2312-80 standard to the GBK normative translation, beginning is to the transition of GB 18030 (ISO/IEC10646-1:2000) standard, up to the present, still do not solve the desirable Chinese character digital coding input method of multi-lingual Technology of Chinese Information Processing at GB 18030 character set.

Goal in research of the present invention is:

1, deeply resolves relation between Chinese character, parts and the stroke, determine the form of a stroke or a combination of strokes value of information and the positional information value of stroke in Chinese character or parts of stroke.Concern off-set value with the position between form of a stroke or a combination of strokes information sequence valve, stroke and other strokes of stroke, as the code fetch foundation of Chinese character digital coding.

2, realize that character learning is unified with knowledge sign indicating number rule.Coding rule is simple, can see word knowledge sign indicating number.The starting point of coding is to substitute " writing " with " typewriting ", and the people of meeting writing of Chinese characters can be learned in the short time.Word, the unification of Chinese word coding method.Both individual character can be imported, word can be imported again.Simple, numerous method of Chinese character coding is unified, and China, Japan and Korea's method of Chinese character coding is unified.Both can import Chinese simplified and traditional Chinese characters, also can import japanese character, hanja.The unification of the learnability of coding and the input of high-level efficiency Chinese character.

3, set up the multi-lingual character coding system of compliant.Chinese character set meets China's standard GB 2312, GB13000.1, GB 18030 and international standard ISO/IEC 10646-1:2000.Divining by means of characters meets the Hanzi component standard that formulate the State Language Work Committee, and code fetch meets the Chinese-character order of strokes standard that formulate the State Language Work Committee in proper order.

4, be applicable to Chinese platform domestic, international popular.Not only be suitable for common computer Chinese-character input, and be suitable for input Chinese characters such as mobile phone, video request program, DVD, electronic notebook, palm PC.

The present invention is based on the achievement of above target encode Chinese characters for computer for many years research.Substance of the present invention comprises:

1, the code element of digital union code and keyboard

The code element of digital union code is: " 1 ", " 2 ", " 3 ", " 4 ", " 5 ", " 6 ", " 7 ", " 8 ", " 9 ", totally nine numerical keys.

The stroke of Chinese character has tens kinds, use the convention of five " draws radicals by which characters are arranged in traditional Chinese dictionaries " according to the dictionary searching, and digitally coded characteristics, we get five kinds of basic strokes: " horizontal (one) " (containing " carrying "), " perpendicular (Shu) ", " casting aside (Pie) " (comprising " pecking "), " point (Dian) " (containing " right-falling stroke "), " folding (second) " (comprising left folding and right folding), and give sequence valve with these five kinds of strokes, separate provision is: " 1 ", " 2 ", " 3 ", " 4 ", " 5 ".

Chinese character is a more complicated X-Y scheme, be made up of several parts usually, and parts is made up of stroke.The font of Chinese character is decided by stroke and position thereof.Both made stroke identical, and the position difference between the stroke also can constitute different Chinese characters, for example, " in " and " Chu ".Position attribute of a relation between the stroke is an important attribute, can be used as the foundation of encode Chinese characters for computer.Position relation in the Chinese character between the stroke has: " from ", as " eight "; " join ", as " fourth ", " mouth "; " intersect ", as " ten ", " rich " etc.Experiment shows that " intersecting " concerns and the above two easy differentiations, and have more coded message than the above two.Therefore, we will " from " and " joining " concern that merger is that " independence " concerns.Like this, the position of stroke and stroke relation just is reduced to two classes: independent and crossing.And give the position with this two classes position relation and concern off-set value: " 0 " and " 5 ".

We are stroke " " (as the first stroke of a Chinese character among " two ", " king " and end pen) independently, " Shu " (as the first stroke of a Chinese character among " old ", " four "), " Pie " (as the first stroke of a Chinese character in " adopting ", " wind "), " Dian " (as the end pen in the first stroke of a Chinese character in " extensively ", " worm "), " second " (as the end pen in " several ", " gift ") is called " horizontal stroke ", " erect ", " left-falling stroke ", " point ", " folding "." horizontal stroke " (as the first stroke of a Chinese character in " right side ", " wood ") that to intersect with other stroke is called " traversed by "." erect " (as the end pen in " rich ", " string ") that will intersect with other stroke is called " erecting friendship "." left-fallings stroke " (as second in the first stroke of a Chinese character in " solely ", " boat ") that to intersect with other stroke is called " left-falling stroke friendship "." right-fallings stroke " (as the end pen in " again ", " literary composition ") that will intersect with other stroke is called " pressing down friendship "." folding " (as the first stroke of a Chinese character in " again ", " power ") that to intersect with other stroke is called " folding friendship ".

The code of stroke is obtained by its sequence valve and off-set value addition.Therefore, independently the code of " horizontal () ", " perpendicular (Shu) ", " casting aside (Pie) ", " point (Dian) ", " folding (second) " is: " 1 " (1+0=1), " 2 " (2+0=2), " 3 " (3+0=3), " 4 " (4+0=4), " 5 " (5+0=5), and the code of " traversed by ", " the perpendicular friendship ", " cast aside and hand over ", " press down and hand over " is: " 6 " (1+5=6), " 7 " (2+5=7), " 8 " (3+5=8), " 9 " (4+5=9).Draw analogous conclusions, the code of " folding is handed over " should be " 0 " (5+5=10 gets position, end " 0 ").

Consider that digitally coded symbol resources is very precious, use a code element " 0 " less, on digital devices such as mobile phone, use more convenient digital union code.So, not distinguish " folding " and whether intersect with other stroke, no matter regulation " folding " is independent, perhaps intersects with other stroke, its code is " 5 ".Simultaneously, also allowing the code of " folding is handed over " is " 0 ", as alternative mode.

The present invention gives sequence valve " 1 ", " 2 ", " 3 ", " 4 ", " 5 " with stroke, draws radicals by which characters are arranged in traditional Chinese dictionaries with the indexing system for Chinese characters one of most dictionaries and sorts consistent.Can make full use of the existing knowledge of Chinese characters of people like this, conform to, be convenient to the user and accept, thereby digital union code is easily learned with convention.Simultaneously, the position that the present invention has created stroke concerns that giving the position concerns off-set value, and the sequence valve and the off-set value of stroke drawn the stroke code by simple additive operation.Therefore make the present invention both possess creativeness and novelty, possess the practical characteristics of easily learning again.

The probability that appears at first sign indicating number at code element " 7 ", " 8 ", " 9 " is lower, and majority appears at second yard later situation.In order to reduce the repetition rate of coding and to improve code efficiency, choose conducts such as radicals by which characters are arranged in traditional Chinese dictionaries " ten ", " Lv ", " eight ", " mouth " and " surmount stroke member ", give code " 6 ", " 7 ", " 8 ", " 9 ".Simultaneously, allow to replenish and choose a small amount of other radicals by which characters are arranged in traditional Chinese dictionaries, give code " 1 ", " 2 ", " 3 ", " 4 ", " 5 " with radicals by which characters are arranged in traditional Chinese dictionaries " king ", " worm ", " bamboo ", " Rui ", " Si " etc., as alternate ways as " surmounting stroke member ".

Experiment shows, uses radicals by which characters are arranged in traditional Chinese dictionaries as " surmounting stroke member ", can improve code efficiency, reduces the repetition rate of coding.But, too much use " surmounting stroke member ", can influence the learnability of coding.Therefore, the present invention chooses the principle of " surmounting stroke member " and is: code element correspondence " surmounts stroke member " can not be above three." surmount stroke member " and generally will contain the stroke of code element correspondence.As, surmounting stroke member " ten ", the first stroke of a Chinese character is " traversed by ", code is " 6 ".And " eight ", " mouth " are as only two special cases.

Keyboard arrangements of the present invention has dual mode, and a kind of is the numeral row of the big keyboards of digital device such as computing machine, and another kind is the numeric keypad of digital devices such as computing machine, mobile phone.

Accompanying drawing 1 is the big keyboard key bitmap of digital union code.Accompanying drawing 2 is digital union code keypad key bitmaps.

2, the structure type of Chinese character and head and the tail cutting

The structure type of Chinese character has determined the code taking method of Chinese character. The whole nation Language Information Technology Standardization committee is in " Hanzi internal code expansion Standard (GBK) " in be 12 kinds with the structure type of Chinese character: left and right sides structure, left, center, right structure; Up-down structure, the upper, middle and lower knot Structure; The full structure of surrounding is surrounded structure downwards, upwards surrounds structure, surrounds structure to the right, surrounds structure to the bottom right, to left down Surround structure, to upper right encirclement structure; Nested structure. The present invention merges 12 kinds of structure type of Chinese characters, and inductive generalization is four Plant basic structure. They are: up-down structure, left and right sides structure is surrounded structure, nested structure. Be exemplified below:

Up-down structure, as: word, flower, Ji.

Left and right sides structure, as:, plant, do.

Surround structure, as because of, hear, letter, the district, the mausoleum, rise in the pasture, advances.

Nested structure, as: Shen, centre.

Chinese character divides two kinds of single character and combinde rqdical characters, and combinde rqdical character accounts for the overwhelming majority of Chinese character. Up-down structure, left and right sides structure, encirclement knot The word of structure generally is combinde rqdical character, and such word is easy to be split as head and the tail two parts. Nested structure word majority is single character, it Be one integrated mass, be not easy to be cut into parts, perhaps be basic word-building part, again cutting.

The present invention takes dichotomy for up-down structure, left and right sides structure, encirclement block word, word is divided into " prefix " and " word Tail " two parts. The method of cutting prefix, suffix is identical with the method for getting radicals by which characters are arranged in traditional Chinese dictionaries of looking up the dictionary. Press the complete principle of shape, will Chinese character is divided into two. The top word-building part of up-down structure Chinese character, the left part word-building part of left and right sides structure Chinese character, as prefix, All the other are as suffix. Surround the head and the tail of structure Chinese character, press the sequential write division, the word-building part of writing earlier is as prefix, all the other works Be suffix. Non-divided for the nested structure word.

3, code taking method

The present invention stipulates that a Chinese character can get one to six yard. For up-down structure, left and right sides structure, encirclement block word, prefix is pressed The order of strokes observed in calligraphy is got last to trigram, and suffix is according to stroke order got last to two yards and an end code, and whole word is got at most six yards. For nested structure Word according to stroke order, is got last to five yards and an end code. Code taking method is exemplified below: Word 445556 each 3599 32425 kind 367257 hear 425126 and go out 52752 668454 Shens 25667 right 689 rich 6667 are entered at 413251 612515 at mausoleum

The usage frequency of Chinese character is different, only " ", " one ", "Yes", " ", " ", " no ", " with ", " having " The first eight high frequency word just accounts for 10% of the total occurrence number of Chinese character. Therefore, we not only provide whole codes to some everyday characters, And providing " brevity code ", the length of brevity code is respectively 1,2,3 yard. And brevity code must be

front

1,2,3 yard of all-key, The user needn't remember brevity code. Following example "Yes", " ", " ", " no ", " with ", the brevity code of the word such as " having " with All-key: Be 2 251124 6 68,261 5 55 not 1 1324 and 3 3679 121 121134 I in 3 365654 positive 12 12121 the 31 314,563 2 2567

When the input Chinese character, we take the mode by the key prompting, and each the key entry has optional character reminding, and the user gets final product Word selection, and needn't by the time import whole codes. In front 3 yards processes by the key prompting, high frequency brevity code word appears at optional Chinese character The front portion, thereby improved the service efficiency of brevity code.

Match owing to high frequency word brevity code with by the key prompting, only import front 3 yards and just can effectively look for the Chinese character that needs input. Cause This as long as the user remembers nine figure cases, according to stroke order makes a call to 3 keys, how needn't to consider also can to use this by the cutting Chinese character Invention.

4, vocabulary coding

The word code is isometric six yards. First three code of each word coding of the coding of two words forms three words, four words and multiword The coding of word is got the first two code of first, second and third each word of word. During input, words mixes input, needn't distinguish character code and word code.

5, multilingual Chinese character is processed

Chinese character not only uses in China, and uses with the circulation of region in countries such as Japan, Korea S. Because the state of Chinese character circulation Family is different from the region, and the font of employing is also different from character set. And ISO/IEC 10646-1 Chinese character collection comes from China just The JIS standard of the CNS in GB standard series, China Taiwan (Big5) standard, Japan, the KS C standard Chinese character of Korea S symbol collection.

For supporting multilingual Chinese character to handle, the present invention is to the Chinese in the ISO/IEC 10646-1:2000 character set, Japanese, hanja Unified coding.The country of pressing Chinese character circulation is different with the region, and the different subclass of composition digital union code Chinese character input method is promptly taked the method for " enforcement of this diversity of Unicode ".These subclass comprise: Chinese GBK/GB 2312 digital union code Chinese character input methods, Chinese-traditional Big5 digital union code Chinese character input method, Japanese JIS digital union code Chinese character input method, Korean KS C digital union code Chinese character input method.Take the method for " enforcement of this diversity of Unicode ", meet the reality that Chinese character circulation is used, simultaneously, also reduce the repetition rate of coding of encode Chinese characters for computer and repeated code number of words on the same group.

The present invention is the achievement of inventor's two more than ten years encode Chinese characters for computer research.The digital union code clear rules can see that word knows sign indicating number, both can import individual character, can import word again, and the people ten minutes who generally understands writing of Chinese characters learns with interior.Digital union code is easy to learn and use, the input efficiency height, and code element only has 1～9 nine numerical key, 1～6 yard of code length.The digital union code repetition rate of coding is lower, and the repeat code Chinese character number is few on the same group, in GB 2312 character set, 1912 of repeated code words is arranged, and repeat code Chinese character is no more than 10 on the same group, has realized that one page presenting bank shows all repeated code words on the same group.Divining by means of characters meets the Hanzi component standard that formulate the State Language Work Committee, and code fetch meets the Chinese-character order of strokes standard that formulate the State Language Work Committee in proper order.

Digital union code is applicable to multilingual Chinese character processing, can encode to all Chinese, Japanese, hanja in the ISO/IEC 10646-1:2000 character set.The version that is applicable to China GB 2312, GBK, the input of GB 18030 character set Chinese characters is arranged, the version that is applicable to the Big5 of China Taiwan Province character set Chinese character input is also arranged, be applicable in addition the input of Japanese JIS character set Chinese character version, be applicable to the version of Korean KSC character set Chinese character input.

The present invention compares with existing Chinese character digital coding, has solved the contradiction between digitally coded learnability, standardization, the high-level efficiency preferably, and every index is in advanced level.Digital union code not only is suitable for common computer Chinese-character input, and is more suitable in input Chinese characters such as mobile phone, video request program, DVD, electronic notebook, palm PCs.
