Description

Input method of Chinese character based on the four-corner system and radical

The present invention relates to a kind of encode method for entering Chinese characters.

The method of the keyboard coding input Chinese character that uses at present is broadly divided into three major types: sound sign indicating number, font code, pronunciation-form combination code, wherein font code is to encode according to the font and the stroke feature of Chinese character, and the input method of Chinese character that belongs to font code can be divided into three major types again: stroke coding, radical (parts) coding, four corner characteristics coding.Stroke coding is that Chinese character is split into several basic strokes; Form coding according to the order of strokes observed in calligraphy of Chinese-character writing, its feature is study and grasps than being easier to, but the sign indicating number string length, the repetition rate of coding is high, input efficiency is low.The four-corner system of standard with the feature of four corners of Chinese character with 10 numerals, four-corner system input method of Chinese character easily learns, easy-to-use, all be better than stroke coding from the repetition rate of coding and input efficiency, but see on the whole and still have repetition rate of coding height, problem that input efficiency is low.

In font code, the scheme of root coding receives an acclaim because of its input efficiency is high.It is that Chinese character is split into some basic elements of character---radical according to certain rule, just Chinese character is regarded as and is made up of radical.The word that the advantage of root coding scheme is an average code length, the repetition rate of coding is low, efficient is high, can not read also can be imported.In order correctly to split to most Chinese character, the radical that this scheme is selected for use is many, reach up to a hundred or more, these up to a hundred radicals are mapped on the keyboard, represent with 26 English alphabets, represent Chinese character with regard to having realized with the combination of 26 English alphabets like this, realized the encode Chinese characters for computer input.Just belong to root coding as the Five-stroke Method input method of Chinese character commonly used.The difficult point of this scheme maximum is exactly difficult to the memory of the mapping relations of radical and English alphabet, and learning time is long; In order to solve memory problems, most input method is mapped to radical on 26 English alphabets according to stroke, pronunciation or the pictograph feature of radical.As common five-stroke character input method is exactly that stroke feature according to radical comes radical is classified, this input method is five kinds of basic strokes---horizontal, vertical, cast aside, press down, folding combination in twos, two of corresponding radical, have 25 kinds of combinations like this, corresponding 25 English alphabets, realize the radical classification, be convenient to memory.The method of utilizing pronunciation to sort out radical is that this method memory capacitance is little corresponding 26 English alphabets of the initial consonant of radical pronunciation, but repetition rate of coding height.The pictograph method is that the shape information by letter on the shape information of Chinese character root and the keyboard has the similar radical of classifying to a certain degree.The memory capacitance of this scheme is little, but because of will looking after the principle of " likeness in form ", therefore the radical of choosing is not true to type, and the radical size choose also unreasonablely, repetition rate of coding height is difficult to split.In a word, above-mentioned multiple input method of Chinese character all exists the regularity of memory and the contradiction between the individual character code length and the repetition rate of coding.

The purpose of this invention is to provide a kind of four-corner system that makes full use of and look into the easy note characteristics of word rule and input method of Chinese character and the keyboard thereof that radical is imported the low characteristics of the repetition rate of coding.

For achieving the above object, the technical solution used in the present invention is as follows:

Based on the input method of Chinese character of the four-corner system and radical,

Look into the word rule according to the four-corner system, promptly look into the word rule for " it is that the horizontal remnant that becomes is arranged under the point that horizontal one vertical two or three right-falling stroke forks four are inserted five square frames, six heptangles 889 " ten, stroke and morphological feature according to the Chinese character root upper left corner are included into radical " 1; 2; 3; 4; 5; 6,7,8,9,10 " ten big classes; i.e. ten districts; according to the feature in the Chinese character root lower right corner radical in each district is divided into three groups again; be so-called position; the classification principle of bit code is: the stroke feature according to a certain corner of radical reduces three classes with it, the stroke of this corner for horizontal or lack pen then bit code be 1; The stroke of this corner be point, right-falling stroke, perpendicular, cast aside, promptly the then bit code of downward trend is arranged is 2 to the style of brushwork; The stroke of this corner is fork, mouth, the angle of intersecting or connecting and composing by two, and then its bit code is 3; Above-mentioned totally three ten region-position codes are mapped to respectively on any 30 keys of common keyboard

The individual character input

For detachable Chinese character, Chinese character split into radical after, import in proper order according to the pairing key of radical position, abide by following principle when splitting Chinese character and coding input;

(1) corner code taking principle, when referring to split Chinese character not according to the order of writing strokes code fetch of Chinese character, but from four corners of Chinese character by the order in the upper left corner, the upper right corner, the lower left corner, lower right corner code fetch successively;

(2) only get principle one time, refer to when splitting Chinese character such as a certain radical occupies plural corner, then only get root coding one time, needn't repeat to get the coding of this radical;

(3) less than continues to tear open for four yards, refers to that four angles of Chinese character have all been decomposed, but coding four yards of less thaies and also have remaining radical, this moment again according to the corner code taking principle to remaining radical code fetch, till supplying four yards or radical and having split;

(4) repeat code Chinese character adds identification, and the Chinese character repeated code phenomenon of four yards appearance of less than still after referring to finish for code fetch adds an identification code again behind coding, and choosing by the font of this Chinese character and the four-corner system feature in this Chinese character lower right corner of identification code determines jointly; The font of Chinese character is divided into left right model, goes up three kinds of mo(u)ld bottom half, heterozygous, non-left right model and the non-mo(u)ld bottom half of going up are heterozygous, the Chinese character of three kinds of fonts is Q, A, the Z three row's keys on the corresponding keyboard respectively, determine the position of its identification code on keyboard according to the four-corner system feature in the lower right corner of Chinese character again;

For the Chinese character that itself is exactly radical, first of its coding is exactly the code of this radical, second and third, four codings from four corner numbers of getting successively, and use same ten key positions inputs walking crosswise at place, this radical key position by the principle of four-corner system indexing method;

For the Chinese character that is difficult to split into radical according to such scheme, the principle of pressing four-corner system indexing method utilizes ten keys of a certain row of keyboard to replace the input of numerical key direct coding behind four corner code fetches of Chinese character;

The phrase input

Two-character word, every word are got preceding two yards inputs; Its first sign indicating number input all only got in three words, preceding two yards of getting lead-in, second and third word; One yard input got in four words, every word; The multi-character words that surpasses four words, first three word are respectively got its first sign indicating number, and then get the first sign indicating number input of last word.

Technical scheme of the present invention has following advantage: 1) to look into word according to the four-corner system on keyboard regularly arranged for radical, and arrangement regulation is strong, and memory is simple, is easy to study, and weak point takes the time.2) four corners from Chinese character split Chinese character, meet the sequential write of Chinese character, and the process of divining by means of characters is easier.3) repetition rate of coding is low, high input speed.

Further specify the present invention below in conjunction with drawings and Examples:

Accompanying drawing is the distribution diagram of radical on keyboard in one embodiment of the present of invention.

The present invention has utilized some rules in the four-corner system indexing method, is necessary that therefore this indexing method is done one suitably to be introduced.This indexing method is regarded Chinese character as Chinese characters, gives each Chinese character four figures according to the stroke combination characteristics at its upper left corner, the upper right corner, the lower left corner, four angles, the lower right corner, realizes the coding of Chinese character.This indexing method is classified as ten kinds to the dihedral characteristics of Chinese character, and its pithy formula is: horizontal one vertical two or three right-falling strokes, and fork four is inserted five square frames six, and heptangle 889 is little, has horizontal change odd under the point.Promptly numeral 1 is represented the form of a stroke or a combination of strokes " horizontal stroke " and " choosing "; 2 representatives " erecting " and " left-falling stroke ": 3 representatives " point " and " right-falling stroke ", 4 represent two intersections: 5 represent vertical wearing more than two or two; 6 representative " mouth " fonts; 7 represent the dihedral of a turnover or to the right or two nibs formed dihedral that joins downwards; 8 representative " eight " font and distortion thereof; 9 representative " little " font and distortion thereof; 0 representative " point " and " horizontal stroke " combines.Utilize this pithy formula during to the Chinese character code fetch, following principle to be arranged, 1 from the direction at four angles) a certain form of a stroke or a combination of strokes, anterior angle was used, and then the coding at this angle is also represented with 0, as (king 1010), (winter 2730).2) some stroke, as " L ", though be one, the first stroke of a Chinese character is different with the form of a stroke or a combination of strokes of receiving pen, in this case one can the subangle number of getting, as (with 2870), (disorderly 2261), (7 4071).3) one two sections constitute two kinds of forms of a stroke or a combination of strokes with other pen, divide two jiaos of numbers of getting, as (half 9050), (wood 4090); The inferior horn form of a stroke or a combination of strokes is partially at one jiao, the number of getting according to actual position via, and unfilled corner does 0, and as (producing 0020), (bow 1702), but " bow " wait when being used as radical, gets 2 lower left corner numbers of making whole word, as (1223).

As shown in drawings, the keyboard of the input method of Chinese character based on the four-corner system and radical of the present invention, be to look into the word rule according to the above-mentioned four-corner system, stroke and morphological feature according to Chinese character root are included into ten districts respectively with it, according to the classification principle of bit code the radical in each district is divided into three positions again, above-mentioned 30 bit codes are mapped to respectively on 30 keys of keyboard, the Q of selection standard keyboard, A, Z key are 1 district in the present embodiment; W, S, X key are 2 districts; E, D, C key are 3 districts; R, F, V key are 4 districts; T, G, B key are 5 districts; Y, H, N key are 6 districts; U, J, M key be 7 districts: I, K,, key is 8 districts; 0, L, o key are 9 districts; P; ,/key is 0 district.The bit code of first letter key in aforementioned each district is 1, and the bit code of second letter key is that the bit code of 2, the three letter keys is 3.When radical is mapped on the keyboard at first stroke and the code name of morphological feature in four-corner system indexing method according to this radical it is included into corresponding district, as radical " bow ", " cutter ",, the stroke feature in " west " etc. all is " horizontal stroke ", belongs in 1 district; Radical in the same district is mapped to respectively on three bit code keys according to the classification principle of bit code, and the classification principle of bit code is as follows: the stroke feature according to the lower right corner of radical reduces three classes with it, stroke for horizontal or lack pen then bit code be 1; The stroke in the lower right corner is point, right-falling stroke, perpendicular, left-falling stroke, and promptly the style of brushwork is oriented, and the then bit code of following trend is 2; The stroke in the lower right corner is fork, mouth, the angle of intersecting or connecting and composing by two, and then its bit code is 3.As above-mentioned radical " bow ", " cutter ", " west " though all belong to 1 district, but the stroke feature in " bow " and " cutter " lower right corner " has downward trend ", its bit code is 2, and the stroke feature in the lower right corner in " west " is " by two mouths that connect and compose ", so the bit code in " west " should be 3.

In sum, the radical of Chinese character is mapped on 30 key symbols as shown in the table according to mentioned above principle:

Q 11	W 21	E 31	R 41	T 51	Y 61	U 71	I 81	O 91	P 01

First figure place of the numeral in the last table is represented district's sign indicating number at this key symbol place, and second order digit is represented bit code.

During the radical mapping, except that the foundation mentioned above principle,, also to follow following particular provisions in order to reduce repeated code and to improve input speed:

1. ten keys of Q row also distribute ten defined dihedrals of rule of four-corner system indexing method and form of a stroke or a combination of strokes feature except that the radical of arranging to determine as stated above, are shown by the Q key table as horizontal stroke; Point, right-falling stroke etc. are shown by the E key table." second " is defined as point in the present invention, presses down class, and the E key table shows.

2. for the ease of memory, the radical that regulation is made up of two or three identical or similar strokes, then its stroke number is bit code, is 2 as the bit code of radical " two ", and the bit code of radical " three " is 3.Two perpendicular bit codes are 2, and the bit code of radical " river " is 3.

3. for reducing the repetition rate of coding, regulation radical " ear, Fu, Jie " is by " C " expression, and character " C " outward appearance elephant ear is sorted out by pictograph.Radical " stone, Myeon, watt " shows by ". " key table, and stone is with ". " key characters pictograph, so radical " stone " is returned this key, radical " Myeon " is " stone " two.Watt also be a kind of stone." boat, fish, Quan " casts aside the first stroke of a Chinese character, and fish, boat also be elongated on image, so be referred on "/" key.

4. in the four-corner system, 5 represent one vertically to wear two, or vertical wearing more than two.Represent one vertical to wear two but be defined as 5 in the present invention, but not vertical wear two-more than.Mapping relations between concrete radical and the key position see table:

92	L	Fire rice Xiangxi	The original shape of " Xiangxi " is " fire "
				93		Shi Myeon watt
01	P	The wide Epileptic pig of Http Tou clothing Yi is upright	The original shape of " Yi " is " clothing ", the bottom of " pig " similar " clothing ".
				02		Say civilian side Yan	The original shape of " Yan " is " speech "
03	/	Boat fish Quan dog	" dog " is the original shape of " Quan "

Input method of Chinese character based on the four-corner system and radical of the present invention, its Chinese character input process is as follows:

For detachable Chinese character, get the radical of four corners in the Chinese character upper left corner, the lower left corner, the upper right corner, the lower right corner, import according to following principle:

(1) corner code taking principle, when refer to splitting Chinese character not according to the order of writing strokes code fetch of Chinese character, but from four corners order code fetches of Chinese character, the order of code fetch can be set arbitrarily, for identical with the sequential write of Chinese character, the order of regulation code fetch is the upper left corner, the lower left corner, the upper right corner, the lower right corner in the present embodiment.As: separate (cutter, the moon, cutter, ox).

(2) only get principle one time, refer to when splitting Chinese character such as a certain radical occupies plural corner, then only when this radical occurs first, get its coding, no longer get the coding of same radical later on.As: " according to " upper left corner of word and the radical in the lower left corner all be " in ", only get radical one time, be split as " according to " (Rolling, corpse, Gu); The upper left corner of " village " word and the radical in the lower left corner all are " wood ", and the radical in the upper right corner and the lower right corner all is " very little ", split into " village " (wood, very little); The upper left corner of " dew " word and the radical in the upper right corner all are " rain ", split into " dew " (rain, foot, mouth): the upper left corner of " government official " word and the radical in the upper right corner all are " Http ", the radical in the lower left corner and the lower right corner all is " suffering ", splits into " government official " (Http, suffering).

(3) less than continues to tear open for four yards, all has decomposed at four angles that refer to Chinese character, but coding four yards of less thaies and also have remaining radical, this moment again according to the corner code taking principle to remaining radical code fetch, got up to supplying four yards or radical, as meaning (upright, the heart, day), fine jade (king, big, fourth, mouth), sharp (Rui, father, The-Fan, side).

(4) repeated code adds identification, behind the coding, repeated code might occur as stated above, the corresponding identical coding of promptly a plurality of Chinese characters.The radical that Chinese character splits is fewer, can occur this repeated code phenomenon when having only two or three radicals.For fear of this problem, for four yards of less thaies, behind root coding, add an identification code again.The dihedral characteristics of choosing by Hanzi font and its lower right corner of identification code determine jointly: it is left right model, last mo(u)ld bottom half, heterozygous that the font of Chinese character is divided into three kinds, and non-left right model and the non-mo(u)ld bottom half of going up are defined as heterozygous.At first determine identification code where arranging on the key in three row's keys according to the font of Chinese character, specific as follows: the Chinese character of left right model, its identification code are one of ten keys of Q row; The identification code of last mo(u)ld bottom half is one of ten keys of A row; The identification code of heterozygous is one of ten keys of Z row.And then according to the four-corner system look into the word principle, determine that according to the dihedral characteristics in the Chinese character lower right corner identification code is which key in ten keys of a row.1,2,3,4,5,6,7,8,9,00 numeral of the from left to right corresponding four-corner system indexing method of every row's key.As the rising sun (nine, day), Ga (nine, day), both radicals are identical, must add identification code in order to distinguish, and " rising sun " be investing mechanism, belongs to the heterozygosis class, and the lower right corner is right-falling stroke, and then identification code is " C ", and Ga is that up-down structure, the lower right corner are square shape, and then identification code is " H ".

For the Chinese character that itself is exactly radical, first of its coding is exactly the code of this radical, second and third, four codings by the principle of four-corner system indexing method from the lower left corner, the upper right corner, the lower right corner number of getting, do to use ten keys inputs of Q row.As the FOPP that is encoded to of " wood " word, " greatly " word be encoded to FIPP.

For the Chinese character that is difficult to split into radical according to such scheme, can be decomposed into radical though that is to say these words, not too directly perceived, in this case can be by the principle direct coding input of four-corner system indexing method, available certain row replaces the numerical key input as ten keys of Q row.As " with " word, be 2112 with the order number of getting in the upper left corner, the lower left corner, the upper right corner, the lower right corner, then it is encoded to WQQW, and for example " beggar ", and the four-corner system is 1002, then it is encoded to QPPW.

For the input of phrase, two-character word, according to above-mentioned code taking rule, preceding two yards inputs got in every word, as country (YQPP), lanes and alleys (HRQV); Its first sign indicating number input all only got in three words, preceding two yards of getting lead-in, second and third word, as the Communist Party (VIPO), and scientist (SROP); One yard input got in four words, every word, as the Chinese phonetic alphabet (D; TP), Australia (DFSQ).Surpass the multi-character words of four words, get first three word and last word, according to the method input of four words groups, as the People's Republic of China (PRC) (TIIY), Algeria (CSAQ).

In this input method of Chinese character, except root coding scheme input Chinese character is provided, a kind of the method for using four-corner system input Chinese character and phrase also is provided, this scheme promptly can be imported with numerical key, also can replace the numerical key input with character keys, when importing with character keys, respectively corresponding 1,2,3,4,5,6,7,8,9,00 numeral of each ten key of the Q on the keyboard, A, Z row, during the input individual character, only use Q row key; During input double word phrase, every word is got preceding two yards, uses Q, A two row's key inputs; When importing three words groups, preceding two words are respectively got one yard, use Q, A two row's keys, and the 3rd word is got two yards, uses the input of Z row key; Its first sign indicating number got in every word when importing four words groups, uses Q, A, the input of Z, A row key successively; Get each one yard of first three Chinese character and last Chinese character when importing the above phrase of four words, by the method input of four words groups.For unified mutually with the root coding scheme, the present invention's regulation, during with the method input Chinese character, code fetch be the upper left corner, the lower left corner, the upper right corner, the lower right corner in proper order, the number of getting of this and four-corner system indexing method is in proper order different.As meter (EURP), to calculate (IRIR), machine (ROUE) is (WOPP), calculates (EUKF) computing machine (EUKV), department of computer science (EKVS).

The radical that uses in the embodiments of the invention can have multiple scheme, no matter adopts which kind of radical scheme, all can realize the mapping and the Chinese character input of radical and keyboard according to technical scheme provided by the invention, needn't repeat at this.

In the technical scheme of the present invention, the specific corner of Chinese character or radical can be determined in different embodiment as required, and as stipulating among the above-mentioned embodiment: the specific corner when determining the bit code of radical is the lower right corner, also can stipulate other corners; The repeated code of regulation Chinese character identification corner is the lower right corner in the foregoing description, also may be prescribed as other corners.
