Description

Chinese-character isomorphic input method for computer

The invention belongs to the field of computer Chinese input method, specially refer to a kind of transmission method that utilizes Chinese-character isomorphic.

Existing Chinese character input method is not hundreds of down, and they roughly can be divided into three types imports in computing machine, promptly uses phonetic entry, imports with handwriting input and keyboard.These three types are all in use, but they respectively have weak point:

1, phonetic entry is difficult to promote, and main cause has two, one, and different Chinese character pronunciations only have more than 400, and different Chinese characters, only Chinese characters of level 2 just have more than 6,000, and phonetically similar word is too many, and only depending on sound is to be difficult to distinguish; The 2nd, the pronunciation difference of the different regions of same Chinese character is very big, and different local people listen the other side to speak, often have any problem, furthermore machine?

2, handwriting input does not have the beating keyboard input to popularize so far, and main cause also has two: the one, and prior art is not high to the discrimination of handwritten Chinese character, and the degree of recent inaccessible practicality; The 2nd, handwritten Kanji recognition needs some special soft, hardware, and price is higher relatively at present.

3, keyboard and input method also has hundreds ofly, only talks representative three kinds commonly used here: the Five-stroke Method (being king's sign indicating number), spelling input method and five stroke input methods.

The major advantage of the Five-stroke Method is that the repetition rate of coding is low, if after grasping its coding rule, input speed is very fast, but its deadly defect is the difficulty grasp of its coding rule, even grasp, also easily forgets if be of little use.

The major defect of phonetic input is a repetition rate of coding height, and single have more than 6,000 with regard to Chinese characters of level 2, but different Chinese character pronunciation methods, surplus having only 400, thereby its average repetition rate of coding just surpasses 10, and the identical Chinese character of encode can reach up to a hundred individual, so its input speed is very low.The big shortcoming of it another is: except that North China was gone into, the general support of other local people's the Chinese phonetic alphabet was held inaccurate, thereby, just lower with its input Chinese character speed, in addition, also have many people can the Chinese phonetic alphabet.

The major defect of five stroke methods is: its repetition rate of coding is equally matched with Chinese phonetic alphabet method, so its input speed is also very low, likes the people of usefulness few.

In sum, present Chinese character input method, or because of its technology does not reach universal degree as yet, or higher because of its price, or because of its coding rule is difficult to grasp, or too high, thereby using their people's ratio little at present because of its repetition rate of coding.For the needs of reforming and opening up to the outside world, China will go to the world, and how as early as possible in line with international standards be so to remove to develop a kind of progressive that has more, can make that the numerous common people are easy to accept not only quick but also utilize the new method of computer input of Chinese characters accurately just becomes current urgency problem to be solved.

Purpose of the present invention: grasp in order to overcome the difficulty that exists in existing many Chinese character input methods, defectives such as difficult memory and repetition rate of coding height, we attempt to seek a kind of new Chinese character input method, its coding rule will simply arrive the people of any one meeting writing of Chinese characters, can both grasp it like a cork, and, only just can import all Chinese characters with the not additional Western letter key of 10 numerical keys, its repetition rate of coding is lower than spelling input method and five stroke methods significantly, Shu Ru speed is significantly fast simultaneously, and this input method can become the method that only just can realize efficiently importing Chinese character with the mobile phone and the palm PC of 10 numerical keys, and the wider computer keyboard input method of present use, all must could import Chinese character with 26 English alphabets, both be not easy to promote, also should not on mobile phone and palm PC, have used; This method is in order to seek thoroughly to upgrade and be suitable for the new method of popularization.

The objective of the invention is a kind of computer Chinese-character isomorphism input method of relying on following technical scheme to realize, comprise following several sections:

(1) based on the Chinese character stroke sorting technique in the prior art, with Chinese character stroke by trend and shape be divided into horizontal, vertical, cast aside, press down, folding five classes, and compose successively with coding, now be listed as follows:

Table 1

Stroke title stroke is moved towards stroke and distortion stroke encoding thereof

A horizontal left side → the right side one

(2) select 19 of Hanzi components that the repetition rate of coding is had the greatest impact,, they are divided into 5 classes as critical component, most for having the other parts of left avertence, and tax now is listed as follows to encode 6,7,8,9,0:

Table 2

Hanzi component example word component coding
	By the handle, mouthful other carry, breathe out 6
Car is other, foot is other,, follow away it, 3 water channels, the Chinese 7
	Language, other, other good, the grandson 8 single sides of son of antimony woman by the Yan, by the Jin
Wood is other, the other poplar of horse, drive the other sign indicating number of other, the anti-dog of 9 stones, mad
	By the worm, by the Lv head, mosquito, careless 0 fish, the other eel of Si, warp

Mnemonic(al) rule for table 2 is:

Chinese caterpillar fungus fish silk, coding 0;

Stone dog wooden horse, coding 9;

People's words gold woman, coding 8;

(3 points) waterwheel foot is walked it, coding 7;

By the handle mouth, coding 6.

(3) other important Hanzi component maybe can contain the folding stroke of definition in the table 1, or contain a longest non-folding stroke, we claim that such folding stroke or the longest stroke are the feature stroke, and these parts are pressed the feature stroke classify, the coding of giving them is that the coding of its feature stroke is exactly the coding of these parts.Now be listed as follows:

Table 3

Hanzi component feature stroke position example word	Component coding
		Upright other, the other station of the horizontal stroke left avertence of WAWQ, smelting	1
Other the arriving of the perpendicular stroke right avertence of upright cutter Dao	2
		By it, the other perpendicular stroke left avertence of ear other this, get by the king, the other top gem of a girdle-pendant of rice, grain carry locations such as soil is other
Fire is other, vow the other combustion of other Pie stroke left avertence, know that other, the red side of literary composition is refined, conspicuous opens other or the like shape			3
	Factory's head, wide head, Pie stroke prefix are pressed, are spent Epileptic head, a bamboo mole, build
Put on anti-civilian, the other right-falling stroke of friendship stroke right avertence side, glue		4
	The other stroke suffix of pressing down of having good luck is gone to
By the power, owe other, strength, by the joyous bird, page or leaf is other, the other dove of folding stroke right avertence, face is seen other, by the melon, look, by the fox dagger-axe, by each, play, by the lattice last of the twelve Earthly Branches, right double-contracting is complete, nation			5
	Other, residual, evil day of bad side, tooth are other, by the order, by other bright, the eye Cannibals of folding stroke left avertence, by the Yi, drink, mend other or the like the congee of bow

Other exclude the other parts of right avertence in the table, and its coding also is to be decided by its feature stroke encoding.

Mnemonic(al) rule for table 3 is:

Upright cutter Dao coding 2;

Other coding 4 handed in anti-literary composition;

See the power bird, respectively owe dagger-axe, page or leaf last of the twelve Earthly Branches melon, right double-contracting, coding is 5 entirely.

(4) said isomorphism Chinese character, it is defined as:

For arbitrary Chinese character, if it contains listed critical component in the table 2, or contain listed vitals in the table 3, then be called the isomorphism word, otherwise claim non-isomorphism word; This claims the Chinese-character isomorphic input method for foundation stone of the present invention comprises the input method of isomorphism Chinese character and non-isomorphism Chinese character sum total.

(5) the Chinese-character isomorphic input method of single word is carried out computing machine input according to following coding, wherein individual character be encoding to many five digit number:

As: " number " be encoded to 43314; D score be encoded to 124;

Rule (a):

The coding of non-isomorphism Chinese character is made up of its preceding two and last three coding, and the coding by its whole strokes that less than is five is formed;

As: the coding of " weight " is 31121; Coding as " together " is 25251, " on " coding be 211;

Rule (b):

The coding of isomorphism Chinese character is to stipulate like this:

(b1):, form by preceding two of its non-isomorphism part, last two and the other coding of above-mentioned right avertence to the other isomorphism Chinese character of right avertence.

As " to " be encoded to 15212; The coding of " putting " is 41354; The coding of " crane " is 35215

(b2): partly preceding two form with last two coding for other isomorphism Chinese characters other to non-right avertence, the coding of its coding or radicals by which characters are arranged in traditional Chinese dictionaries other by its left avertence and non-isomorphism.

As: the coding of " continuing " is 05351; The coding of " structure " is 93554;

The coding of " keeping away " is 75112; The coding that does is 64151.

If not four of isomorphism coding less thaies partly then are made up of the coding of these whole strokes partly and the coding of its radical or radicals by which characters are arranged in traditional Chinese dictionaries.

As: " as " coding be 8251; The coding of " sign indicating number " is 9551.

For what above-mentioned rule should be specifically noted that be, to the other isomorphism Chinese character of right avertence, the coding of its radical is placed on last position of its coding, and other isomorphism Chinese characters, the coding of its radical or radicals by which characters are arranged in traditional Chinese dictionaries is positioned at first of its coding; The purpose of making this regulation is to reduce the repetition rate of coding of encode Chinese characters for computer.

For above-mentioned rule, can be summarised in the table 4:

Table 4

Chinese character name encoding Sample Rules
	Non-isomorphism word preceding two and last three coding 1) with → 25251
Preceding two of the other non-isomorphism part of right avertence, last crane → 35215 isomorphism words, two and the other codings 2 of right avertence) look → 45245
	Keep away before the other component code of non-right avertence, the non-isomorphism part → two of 75112 isomorphism words and last two Zhus' coding 2) do → 64151

1) be less than 5 strokes of persons as whole strokes, adopt the coding of its whole strokes, example " wood ", it is encoded to 1234;

2) partly be less than 4 strokes as non-isomorphism, with the coding of component code and this part whole stroke, it is encoded to 8425 example " ".

Do an explanation with listed " doing " word in example one hurdle, the other parts of left avertence are handle, and component code is 6, and the first stroke " Dian " is encoded to 4, the second " one " and is encoded to 1 in preceding two of the non-isomorphism parts, pen second from the bottom in last two

Be encoded to 5, finishing touch " " is encoded to 1, so be 64151.

(6) for the special processing of high frequency word:

As everyone knows, many high frequency words are arranged in the Chinese character, as:, through, I, be or the like, by above-mentioned rule, the code length majority of these high frequency words is 5, for further improving input speed, just some special processings done in these high frequency words that usually occur, we have introduced the notion of one-level, secondary, three, and so-called one-level brevity code only need hit a numerical key and space bar just can be imported, and we are called one-level brevity code (Chinese character), in like manner, only need hit that two numerical keys and space bar just can import, we are called two utmost point brevity codes (Chinese character), and the rest may be inferred.For ease of narration, we call true form to the original coding of high frequency word, true form as "Yes" is 25134, and its brevity code is 2, in other words, during with the isomorphic input method typing, key in 2 and 25134 and can import the "Yes" word, therefore be not difficult to find out: use the brevity code typing, can improve input speed greatly.

Table 5, table 6 and table 7 have provided one-level, secondary and three respectively, wherein, one-level brevity code word reaches 10, totally 50 of secondary simple code Chinese characters, totally 250 of three words are rescued the brevity code of 310 Chinese characters certainly and are counted all short than their true form extremely greatly, in the typing process, with brevity code and true form can, for example " I " word can both be imported with its brevity code " 3 " and true form " 31534 ".In fact, as a word brevity code is arranged, then its brevity code must be first of its true form, or front two, perhaps therefore front three, needn't remember it, only needs in the typing true form, stare at the presenting bank of screen below,, just press options button and get final product in case desired word occurs.

As can be seen, the length overwhelming majority of brevity code lacks than their strokes separately, and, nearly all be everyday character, so the input speed of this input method is fast certainly.

Below be brevity lists, table 5-table 7

(7) about the isomorphism input method of phrase:

Among the present invention, also be no more than 5 for the coding of phrase, its coding rule is as follows:

1. two-character word group: preceding two yards of every word; As key in after the 4 figure place sign indicating numbers and required phrase do not occur in the presenting bank, then append identification code 0.

For example: " phrase " → 8502; " coding " → 0495; Required speech has appearred after keying in 4 figure place sign indicating numbers;

" rule " → 11250; Required word do not occur after keying in 4 figure place sign indicating numbers, then append identification code, required phrase promptly occurs.

2. three words groups: preceding two prefix coees and last word preceding two yards; As key in after the 4 figure place sign indicating numbers and required phrase do not occur in the prompting back, then append identification code 0.

For example: " Zhong Guan-cun " → 2491; Be good for into 4 figure place sign indicating numbers and occurred required speech;

" Beijing " → 24410; Need append identification code;

3. the above phrase of four words: the first sign indicating number of first three word and last word.As key in after the 4 figure place sign indicating numbers and required phrase do not occur in the presenting bank, then append identification code 0.

For example: " violent storm " → 2391 needn't add identification code and required speech promptly occur.

" People's Republic of China (PRC) " → 23320, key in 4 figure places after, required speech appears in the end, appends identification code 0 and gets final product.

Every key finishes 4 yards problems of whether appending identification code, need not remember separately and division, and eye is stared at screen can pleasant operation.

Compared with the prior art good effect of the present invention, has the following aspects:

1, easily to grasp memory capacitance little for this programme, the Five-stroke Method is encoded with 130 radicals, use the Five-stroke Method input must remember 130 radicals and their coding, and isomorphism word input method need be remembered is 19 critical components and their coding, and the ratio of both memory capacitances is 130: 19.

2, for the beginner, the pass of divining by means of characters of the Five-stroke Method method is sad, and this programme does not then have the Guan Keyan of divining by means of characters.

3, need impact 26 English alphabet keys with ten fingers, and this method only needs to move on the arabic numeral of 0-9 with 5 fingers in the keystroke process, the keystroke scope is dwindled greatly.

4, Zui Da characteristics are on the mobile phone that has only numeral or use on the palmtop computer, its typing effect all more has actuality and convenience than any method, especially for the needs occasion (as the foregrounding person of financial world, hospital, shop, the cashier of restaurant etc.) of typing numeral and Chinese character in turn continually, if with isomorphism method input Chinese character, they only need just can finish the work with Arabic word keypad.And this programme grasp in a single day, be difficult for forgetting.

5, the input efficiency of this isomorphism input method of Chinese character is higher, and the page turning number of times is less in the typing process.

Statistics proves, in more than 6,000 Chinese characters of level 2, gives birth to surplus having only 360 and wards off word and need page turning just can find, simultaneously, the Chinese characters in common use more than 80 percent can be imported with its coding and space bar, so, compare with five stroke input methods with all-phonetic input method, the repetition rate of coding of isomorphism method is more much lower than them, thereby, the efficiency of inputting of isomorphism method is also much higher, see accompanying drawing 2a, 2b, behind the keystroke often all repeatedly page turning just can find required word, and this method need not page turning.Example is gone into key feeding character: " gradually " is " 71 " with this isomorphism method brevity code, do not need page turning to show, and when importing with spelling, key in alphabetic string jian and also will turn over 3 pages outward, promptly want naked eyes in nearly 40 Chinese characters, to find out this word, both time-consumingly also try one's eyes, the time is slow, and efficient is low.

Fig. 3 illustrates the weak point of this isomorphic input method code length than five strokes, also need not page turning during typing, and spelling and five stroke methods are what to do less than this point.

Compare with handwriting input, owing to introduced one, two, three brevity code notion among the present invention, when using the typing of isomorphism method, the code length of most of Chinese characters all lacks than its stroke, as: the brevity code of " I " is 3, and code length has only 1, and it has 7 strokes; The brevity code of " prestige " is 4, and code length also is 1, and it has 11 strokes, hit the velocity ratio of key write 7 strokes, 11 strokes speed fast what doubly? so the input speed of isomorphism method is better than hand-written certainly, and faster.Moreover, hand-writing input method also needs a kind of special writing pen and the screen that writes, thereby its cost is than isomorphism method height.Advantage on efficiency of inputting and the cost will be converted into competitive edge.

Can foretell that the efficient of phonetic Chinese character input method in considerable time from now on, is unable to catch up with this method, in addition and the phonitic entry method ratio, the isomorphism method has the advantage on accuracy and the cost equally.

In sum, the isomorphism input method of Chinese character has various comprehensive advantages significantly; Be exactly easily to learn, easily grasp, be difficult for forgetting; The efficiency of inputting height, the repetition rate of coding is low, and cost is low.

At present, exchanging with surfing Internet with cell phone is a megatrend, the interchange if the hundreds of millions of Chinese in the whole world surfs the Net, writing, and their main language is Chinese naturally, the isomorphism method will become majority's first-selection; Along with enriching day by day of provisioning, the queuing phenomena that was seen everywhere before 20 years, now, still exist in bank, hospital and some other place of paying the fees, if improve the relevant personnel's work efficiency with the isomorphism method, can alleviate queuing problem, so we deeply convince: the multinomial advantage of isomorphism method make her have wide application space and use before.

Further specify the embodiment situation of this method below in conjunction with accompanying drawing.

Fig. 1 is that the code length between this isomorphic input method and the five-stroke character input method compares.

Fig. 2 a is for single Chinese character, and spelling input method and isomorphic input method page turning number of times are relatively.

Fig. 2 b is for phrase, and spelling input method and isomorphism method page turning number of times are relatively.

Fig. 3 is that five stroke input methods compare with isomorphic input method code length and typing effect.

Fig. 4 utilizes the isomorphic input method encoder dictionary for example.

Embodiment: we embed Chinese-character isomorphic input method in the UCDOS operating system, in WPS and two kinds of editing machines of EDIT, carried out the typing experiment, experimental result proves that we have reached goal of the invention, and effect is excellent, and table 7 has shown a part of utilizing isomorphism method input method typing encode Chinese characters for computer.
