[0001] The invention belongs to the technical field of Chinese character input method, in particular to a character source input method. Background Art

[0002] Chinese keyboard input methods are currently mainly divided into shape codes, phonetic codes, shape-phonetic codes, phonetic-shape codes and irrational codes. The more popular input methods include full-pinyin input method, double-pinyin input method, Wubi input method, Cangjie input method, etc. These input methods each have their own advantages and disadvantages. For example: the phonetic code input method (such as Sogou Pinyin) is based on Hanyu Pinyin, which is simple and easy to learn, but has the problems of many duplicate codes and slow speed; the Wubi input method is based on the shape of Chinese characters, with few duplicate codes, suitable for skilled users to achieve blind typing, but it is difficult to learn, and there are a large number of problems such as irregular distribution of radicals and violation of official stroke order rules; the Cangjie input method is mainly for traditional Chinese characters, and the input efficiency of simplified Chinese characters is not high;

BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 It is a flow chart of the character source input method of the present invention. DETAILED DESCRIPTION

[0025] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] The present invention provides a character source input method, such as Figure 1 As shown, including:

[0027] S1. Formulate a character root key map, divide the character roots into three categories of heaven, earth, and man according to the meaning of Chinese characters at the beginning of their invention, and further subdivide and distribute them to different positions on the keyboard, wherein the character roots of heaven are located in the bottom row of the keyboard, the character roots of earth are located in the top row of the keyboard, and the character roots of human are located in the middle row of the keyboard;

[0029] S3, Chinese character encoding, encoding the Chinese character according to the split radicals and their corresponding key positions, taking the first, second, third, and last radicals for more than four codes, wherein the encoding of the Chinese character is composed of the key positions corresponding to the split radicals;

[0030] S4, formulate identification code, for one, two, three radicals of the word respectively take different full spelling prefix as identification code, four or more radicals when no identification code, wherein, one radical of the word take the first three letters of the full spelling as identification code, two, three radicals of the word take the first letter of the full spelling as identification code;

[0031] S5, formulate a simplified code, formulate one, two, three and four simplified codes based on the full Chinese character code, reduce the code length, wherein one simplified code is a commonly used and often single-use Chinese character formulated based on the first code of the full Chinese character code, and the second simplified code is a commonly used word and key name formulated based on the first two codes of the full Chinese character code;

[0032] S6, formulate word codes, and encode two-character words, three-character words, and words of four characters or more according to specified rules, wherein the first two codes of each character are used for two-character words, the first codes of the first two characters and the first two codes of the third character are used for three-character words, and the first codes of the first, second, third, and last characters are used for words of four characters or more;

[0033] S7. Formulate a tonal pinyin code table to realize the input of Chinese pinyin with tones. The tonal pinyin code table uses specific symbols to represent the light tone and the first, second, third and fourth tones, which are separated from the Chinese character encoding. Chinese pinyin with tones can be input simultaneously without interference.

[0034] The following further describes the above content in conjunction with embodiments.

[0035] Embodiment: A character source input method, including:

[0036] First step, formulate a root key table: Divide the root characters into three major categories of heaven, earth, and human according to their meanings at the beginning of the invention of Chinese characters, and then divide each major category into small categories to obtain:

[0037]

[0038] Heaven category: gold, wood, water, fire, earth, sun, moon, in the bottom row of the keyboard;

[0039] Earth category: fish, dog, bird, grass, bamboo, clothing, silk, mountain, food, household, in the top row of the keyboard;

[0040] Human category: female, person, hand, again (the pictograph of hand), foot, child, body, mouth, speech, in the middle row of the keyboard;

[0041] (Important and easy-to-learn point: Although the root characters of Wubi have certain rules, there are many root characters that do not conform to the Wubi rules and can only be memorized by rote with formulas. However, the root characters of the character source input method have rules at three levels: one is that the three rows of keys respectively correspond to heaven, earth, and human regularly; the second is that the main root characters of each row of keys have rules, such as "gold, wood, water, fire, earth, sun, moon", etc. The third is that the root characters on each key position have rules, such as the root characters "knife, dagger" under the main root of "gold" are all related to metals, and the root characters "horse, ox, sheep, pig" under the main root of "dog" are all related to land animals.)

[0042] Second step, split the root characters: Split each Chinese character according to the root characters that appeared in the first step; (Easy-to-learn point: In Wubi, there are some relatively difficult-to-split radicals, such as "wu, fu, zhui", etc., which have been defined as root characters in the character source and do not need to be split.)

[0043] Third step, Chinese character coding: Use the Chinese character root characters obtained in the first two steps and the key positions corresponding to the root characters to code the Chinese characters. For those with more than four codes, take the first, second, third, and last root characters; (For example: "kou" is split into "扌" and "口". The meaning of "扌" is hand, so it is on the D key, and "口" is on the K key; then the code of "kou" is DK);

[0044] Fourth step, formulate the recognition code: For a character with only one root character, take the first three letters of its full pinyin as the recognition code; (For example: The root character code of the character "yong" is O, then take the first three letters YON of the full pinyin of "yong" as the recognition code; the complete code obtained is OYON);

[0045] For characters with two or three radicals, take the first letter of the full pinyin as the recognition code; (e.g., for the character "折", first take the code "D" of the first radical "扌", then take the code "X" of the second radical "斤", and then take the first letter "Z" of the full pinyin of "折" as the recognition code; the complete code obtained is DXZ); (Important and easy-to-learn point: For the recognition code in Wubi, the user needs to judge the structure and the last stroke of a Chinese character, which often takes some time. While in Ziyuan, the full pinyin is directly used as the recognition code, and the user can instantly identify it accurately. In addition, for polyphonic characters in Ziyuan, there are multiple recognition codes. For characters outside the 2,500 commonly used characters, they are all compatible with the simple five-stroke recognition, and the user doesn't have to worry about not being able to recognize unfamiliar characters.)

[0046] For characters with four or more radicals, only take the radicals and do not take the recognition code; (e.g., for the character "整", take the radicals "木, 口, 攵, 正", and the code is XKFG; when it reaches four codes, there is no need to take the recognition code anymore; if there are more than four radicals, only take the first, second, third, and last radicals).

[0047] Step 5: Define abbreviated codes: The code table obtained after the above steps is called the full code table; since the full code has a relatively long length, abbreviated codes are defined to reduce the code length.

[0048] A one-letter abbreviated character is a character with only one code. When typing, press one key and then space to display it on the screen; the one-letter abbreviated characters in Ziyuan Input Method are all defined based on the first code of the full code of the Chinese character, and those commonly used and often used alone are given priority; for example, the full code of the character "着" is WJZ, and the character "着" is commonly used and often used alone; therefore, it is defined as a one-letter abbreviated character, and only by taking the first code "W" can the character "着" be typed; (Easy-to-learn point: Compared with Wubi, 7 of the one-letter abbreviations in Wubi are forcibly stipulated and can only be memorized by rote; while the one-letter abbreviated characters in Ziyuan Input Method are all regular and there are no exceptions).

[0049] A two-letter abbreviated character is a character with only two codes. When typing, press two keys and then space to display it on the screen; the two-letter abbreviated characters in Ziyuan Input Method are all defined based on the first two codes of the full code of the Chinese character, and those commonly used and the key names (i.e., the first radical on each key in the radical diagram, such as gold, wood, water, etc.) among the characters with two radicals are given priority; for example, the full code of the character "时" is NFS, with only two radicals "日" and "寸", and it is also commonly used, so it is defined as a two-letter abbreviated character, and only by taking the first two codes "NF" can the character "时" be typed; (Important easy-to-learn point: Compared with Wubi, the two-letter abbreviated characters in Wubi can only be memorized by rote and have no rules; while the two-letter abbreviated characters in Ziyuan Input Method have become very regular and are very easy to remember).

[0050] Three-letter abbreviated characters account for the vast majority of Ziyuan. For the vast majority of characters, they appear when typing the third code.

[0051] The main function of four-letter coded characters is to remove duplicate codes; if there are still duplicate codes when a character is typed to the third code, then continue to type the fourth code of the character. For characters with only three codes, also fill in the fourth code with pinyin; such characters are relatively few and most of them are very infrequently used characters.

[0052] Step 6. Formulate word codes: The word coding method of the etymological input method is the same as that of the Wubi input method;

[0053] Two-character words: Take the first two codes of each character;

[0054] For example, etymology =宀子氵厂 = PHCH

[0055] Three-character words: Take the first code of the first two characters and the first two codes of the third character;

[0056] For example, input method =车丿氵土 = GMCB

[0057] Four-character words and above: Take the first code of the first, second, third, and last characters;

[0058] For example, Sharp edge of a sword comes from grinding =宀亼钅屮 = PSZR

[0059] (After completing the above steps, the codes of each Chinese character and word can be obtained; these codes placed in a file are called the code table; thus, the coding of Chinese characters and words is completed);

[0060] Step 7. Formulate the tone-marked pinyin code table: The tone-marked pinyin is made into a code table according to the following example method:

[0061] zhɑnɡzhang’ (single quote, the key on the right side of the semicolon)

[0062] zhānɡzhang; (semicolon)

[0063] zhánɡzhang / (left slash)

[0064] zhǎnɡzhang. (period)

[0065] zhànɡzhang, (comma)

[0066] (Among them, “’; / .,” represent light tone, first tone, second tone, third tone, and fourth tone respectively);

[0067] Step 8. Generate the input method; Import the two code table files generated in Step 5 and Step 6 into the “Duoduo Input Method Generator”, and set “’; / .,” as the coding cut-off key in Step 6 of the “Duoduo Input Method Generator”; then an input method that can be used in the Windows system can be generated; in addition to being able to input Chinese characters using the etymological code scheme, this input method can also input tone-marked Chinese pinyin.

[0068] Furthermore, comparing a kind of etymological input method in the embodiment with the current Wubi and pinyin, the following table is obtained:

[0069]

[0070]

[0071] Through this table, we can clearly see the following characteristics and advantages of the etymology input method:

[0072] 1) Input speed: The Ziyuan input method has only 389 duplicate characters among the 6763 GB characters, which is less than the 510 duplicate characters of the Wubi input method. This means that there are fewer cases where duplicate codes need to be selected during typing, thereby improving the input speed. In addition, after deduplication through simple codes, the number of characters that need to be selected for duplicate codes is further reduced, giving the Ziyuan input method a clear advantage in input speed.

[0073] 2) Ease of learning: Although the etymological input method requires memorizing character roots, its character root distribution is regular, and the identification code is completely recognized by full spelling, which is easy for users to understand and remember. In contrast, the character root arrangement of the Wubi input method is more chaotic, and it needs to rely on rote memorization, and there are many special cases and situations that do not conform to the stroke order rules, which makes it more difficult to learn. Although the Sogou Pinyin input method is simple and easy to learn, it cannot improve the input speed. Therefore, the etymological input method is between the two in terms of ease of learning, and because it is more regular, it is easier to learn than Wubi.

[0074] 3) Chinese character standards: The Etymology Input Method fully complies with the standards for Chinese character radicals and stroke order. There are no meaningless radicals that are split up, and no stroke order that is artificially redefined. This is in stark contrast to the Wubi Input Method, which artificially redefined the stroke order and split up meaningless radicals in order to reduce duplicate codes. At the same time, the Etymology Input Method also complies with the Hanyu Pinyin standards.

[0075] 4) Ability to input pinyin with tones: The Ziyuan input method can input Chinese pinyin with tones simultaneously without any interference, which is one of its unique advantages. For specific user groups (such as primary school Chinese teachers), this function is very practical. However, the Wubi input method and Sogou Pinyin input method cannot directly input pinyin with tones.

[0076] 5) Added value: The etymological input method not only helps users remember the shape of characters and reduce the chances of forgetting characters, but also, because character roots are distributed based on their meanings, more frequent use can help users deepen their understanding of the origin and structure of Chinese characters. This is especially beneficial for primary school students, as it can promote their learning and memory of Chinese characters.

[0077] In summary, the table shows that the etymological input method has obvious advantages in input speed, ease of learning, Chinese character standardization, ability to input toned pinyin, and added value, and is a Chinese character input method worthy of promotion and application.

[0078] Furthermore, in order to optimize the distribution of radicals on the keyboard so that the distribution of radicals is more consistent with the user's input habits and the frequency of use of Chinese characters, an objective function is defined, which comprehensively considers factors such as the frequency of use of radicals, the correlation between radicals, and the length of the user's input path on the keyboard. The optimal distribution of radicals on the keyboard is determined by solving the optimal solution of the function. The formula of the objective function is as follows:

[0079]

[0080] Among them, w i is the weight of root i (determined by frequency of use), f i (x i ) is the root i at position x i The fitness function on g ij (x i ,x j ) is the root i and j in position x i and x j is the correlation function on , and λ is the weight coefficient of the correlation.

[0081] Furthermore, in order to optimize the encoding rules of Chinese characters to reduce the redundancy of encoding and improve the accuracy of encoding, a coding efficiency index is introduced. This index comprehensively considers factors such as the length of the encoding, the uniqueness of the encoding, and the correspondence between the encoding and the Chinese characters. The best Chinese character encoding rules are determined by solving the optimal solution of the index. The formula of the coding efficiency index is as follows:

[0082]

[0083] Among them, N is the total number of Chinese characters, L i is the encoding length of Chinese character i, L max Is the maximum length of all Chinese character codes, U i is the uniqueness index of the Chinese character i encoding (measured by the similarity with other Chinese character encodings), C i It is the corresponding relationship index between the Chinese character i code and the Chinese character (measured by the correlation between the code and the meaning of the Chinese character), and α and β are weight coefficients.

[0084] Furthermore, in order to optimize the generation rules of the identification code to reduce duplicate codes and improve the accuracy of recognition, a recognition efficiency index is introduced, which comprehensively considers factors such as the length of the identification code, the uniqueness of the identification code, and the correspondence between the identification code and the Chinese character; the optimal identification code generation rule is determined by solving the optimal solution of the index, and the formula of the recognition efficiency index is as follows:

[0085]

[0086] Among them, M is the total number of Chinese characters that need identification codes, P j is the length of the identification code of Chinese character j, P max is the maximum length of all identification codes, V j is the uniqueness indicator of the Chinese character j identification code (measured by the similarity with other Chinese character identification codes), γ is the weight coefficient.

[0087] Furthermore, in order to optimize the generation rules of the tone-added pinyin code table to improve the accuracy and efficiency of pinyin input, a pinyin input efficiency index is introduced, which comprehensively considers factors such as the length of the pinyin code table, the uniqueness of the pinyin code table, and the correspondence between the pinyin code table and Chinese characters; the best tone-added pinyin code table generation rules are determined by solving the optimal solution of the index, and the formula of the pinyin input efficiency index is as follows:

[0088]

[0089] Among them, K is the total number of Chinese characters that need to be input in pinyin, T k is the length of the phonetic code table of Chinese character k, T max is the maximum length of all phonetic code tables, W k is the uniqueness index of the Chinese character k phonetic code table (measured by the similarity with other Chinese character phonetic code tables), and δ is the weight coefficient.

[0090] Working principle: By scientifically classifying the radicals according to their original meanings when Chinese characters were first invented and assigning them to different positions on the keyboard, the Chinese characters are then split and encoded based on these radicals. At the same time, the full spelling prefix is ​​used as the identification code to solve the problem of duplicate codes, and by formulating simple codes and word codes to shorten the code length and improve input efficiency. In addition, a pinyin code table with tones is also developed to realize Chinese pinyin input with tones, thus meeting the needs of different users.

[0091] To sum up: the invention reduces the difficulty of learning by scientifically classifying radicals and assigning them to the keyboard according to their original meanings when Chinese characters were invented; improves input efficiency by combining the split radicals and Chinese character encoding; formulates identification codes to effectively solve the problem of duplicate codes and improves input speed and accuracy; formulates simple codes and word encodings to further shorten the code length and facilitate the input of commonly used Chinese characters and words; in particular, formulates a tone pinyin code table to realize Chinese pinyin input with tones, which meets the needs of specific user groups, and is separated from the Chinese character encoding and does not interfere with each other, thereby improving the user experience; overall, this technology takes into account both input efficiency and ease of learning, and solves the shortcomings of existing input methods in tone pinyin input.

[0092] Definitions of the above key terms

[0093] Radical: A basic unit consisting of a number of strokes that can be combined into all Chinese characters. Applied to shape code input methods. (Similar to the radical of Chinese characters, but for the convenience of character decomposition, some are smaller than the radical, and some are larger than the radical.)

[0094] Shape code: Based on the shape of Chinese characters, Chinese characters are split into several radicals and distributed on the keys. When typing, the radicals are combined to form Chinese characters. Such as Wubi input method, Cangjie input method, etc.

[0095] Phonetic code: Based on Chinese Pinyin, you can get Chinese characters by inputting the letters of Pinyin when typing. Such as Sogou Pinyin Input Method, Microsoft Pinyin Input Method, etc.

[0096] Shape-phonetic code: mainly based on shape code radicals, when duplicate codes appear, they are separated by pinyin. Such as etymology input method, Erbi input method, etc.

[0097] Phonetic code: mainly based on pinyin, when duplicate codes appear, the pinyin or root of the Chinese character radical is used to separate the duplicate codes. Such as Xiaohe phonetic input method, etc.

[0098] Irrational code: There is no regular pattern in the encoding of Chinese characters, which is not convenient for human memory and use. Such as the location input method, tiger code input method, etc.

[0099] Repeated code: When an input method still has multiple candidate Chinese characters after entering all the codes in the rules, these Chinese characters are repeated codes. Repeated codes greatly affect the speed of Chinese character input, because when encountering repeated codes, users cannot directly enter the screen and need to pause to select characters.

[0100] Identification code: A scheme to eliminate duplicate codes. That is, if duplicate codes still appear after obtaining Chinese character codes according to the root rules, stroke codes are added to divert the Chinese characters. This reduces duplicate codes.

[0101] Code length: the total number of keys required to input a paragraph of text by the input method divided by the total number of characters in the paragraph. For a single Chinese character, it refers to the total number of keys required to input the character. The shorter the code length, the fewer keys the user needs to press to input the same text, and the faster the speed.

[0102] Code table: Each Chinese character is encoded according to certain rules. All the Chinese characters in a character library (such as the national standard 6762-character character library) are encoded and placed in a TXT document, which is called a code table.

[0103] Pinyin with tones: Pinyin with four tones, such as zhānɡ, zhánɡ, zhǎnɡ, zhànɡ, etc. The main user group is primary school Chinese teachers.

[0104] Blind typing: typing without looking at the keyboard or the monitor. This is only possible when there are very few duplicate codes and when there is no or very little need to select characters.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention.
