Abstract

A Tibetan input method based on an English keyboard: using an English keyboard, Tibetan syllables are used as the basic unit of code input, the Latin transliteration from the base character of the syllable or the first letter of the Latin transliteration of the base character is used as the input code of the syllable, vocabulary The Latin transliteration codes starting with each syllable base word or the first letter of each syllable base word Latin transliteration are separated by spaces. 30 Tibetan letters and 4 vowels are represented by the single and combined keys of the corresponding keys of the English keyboard. When a syllable has a vowel, its coding sequence is: pre-addition, upper addition, base, lower addition, vowel, post-addition, and post-addition. The Latin transliteration of each letter omits the letter a, and there is no When vowel, the Latin transliteration of the base word cannot omit a. The encoding rule of Sanskrit with vowels is from top to bottom, the Latin transliteration of each letter omits a, and the last is the Latin transliteration of the vowel. When there is no vowel, it is still from top to bottom, and the last letter is transliterated in Latin a is not omitted. The coding rule of the vocabulary is: coding plus spaces between syllables.

Description

Tibetan input method based on English keyboard

technical field

The invention relates to the field of Chinese information processing; in particular, it relates to a Tibetan input method based on an English keyboard.

Background technique

The existing Tibetan input methods in China mainly include basic character input method, spelling input method, Latin input method and location code input method. The Wylie input method abroad is the Latin input method. Both the basic character input method and the spelling input method code each character according to the alphabetical sequence superimposed on the top and bottom of a character, and the Latin input method encodes the Tibetan character according to the Latin transliteration of the character. Although these input methods are different, from the perspective of encoding input, their input schemes all use characters as the input unit, and there are different keystrokes according to the number of superimposed layers of a character or its Latin transliteration frequency. For example, the spelling input method needs 3 to 4 keys to input a character with 4 layers (including vowels), and a Tibetan character corresponds to the only code, so it is an inefficient input method, which is far from meeting the needs of Tibetan information processing. need.

Contents of the invention

The purpose of the present invention is to solve the long-standing problem that Tibetan does not have keyboard fast input and intelligent input, and provides a Tibetan input method based on an English keyboard.

In order to achieve the above object, the technical scheme of the present invention is: use English keyboard, Tibetan syllable as the basic unit of coding input, from the Latin transliteration of syllable base word or the initial letter of base word Latin transliteration as the input code of syllable, The Latin transliteration codes of each syllable base word of the vocabulary or the first letter of each syllable base word Latin transliteration are separated by spaces.

1. Coding rules for 30 letters and 4 vowels in Tibetan

Transliteration of 30 Tibetan letters and 4 vowels in Latin letters, using the 23 keys of the English keyboard: a, b, c, d, e, g, h, i, j, k, l, m, n , o, p, r, s, t, u, v, w, y, z respectively correspond to a, b, c, d, e, g, h, i, j, k, l, m, n, o, p, r, s, t, u, v, w, y, z. The Tibetan letters represented by combinations of different numbers of Latin letters are combined with corresponding numbers of keys. The encoding rules for Tibetan 30 letters and 4 vowels are:

ka kha ga nga ca cha ja nya ta tha da na pa pha ba ma tsa

tsha dza wa zha za va ya ra la la sha sa ha a i u e o

such as letters The Latin transliteration nga is a combination of the three keys n, g, a.

2. Encoding rules for 5 anti-words, 5 Sanskrit vowels and common symbols

In Sanskrit, in addition to Tibetan letters and vowels, there are 5 reverse words and 5 vowels. Their encoding rules are:

Da Na SHa THa Ta E I M O H A

在梵文中作为长元音时用A表示。大写字母A、D、E、H、I、M、N、O、S、T分别对应英文键盘的相应键位。the Tibetan alphabet

It is represented by A when it is used as a long vowel in Sanskrit. Capital letters A, D, E, H, I, M, N, O, S, and T correspond to the corresponding keys of the English keyboard.

The codes of commonly used Tibetan symbols and numbers are:

, . { } : * 1 2 3 4 5 6 7 8 9 0

3. Coding rules integrating Tibetan syllables, Sanskrit and Tibetan vocabulary

。The basic input unit of the present invention is a Tibetan syllable. A syllable is a language unit formed by spelling left and right with the base character as the center, superimposed up and down, and according to the combination rules. The combination rules of Tibetan syllables are basic language knowledge for anyone who understands Tibetan. The syllable structure is as shown in accompanying drawing 1 and accompanying drawing 2. The positions of 1, 2, 3, 4, 5, 6, and 7 are respectively base word, upper added word, lower added word, front added word, back added word, back added word and vowel sound. The Tibetan syllables that are completely consistent with the structures in Figure 1 and Figure 2 are as follows: and

.

分别是藏文的单字、双字、三字和四字音节。Among the seven components of the base word, upper added word, lower added word, front added word, back added word, further added word and vowel, except for the base word, the other components are one to six less, and are still syllables . Each vertical unit in a syllable is a glyph. Therefore, a syllable has at least one syllable, that is, the vertical unit where the base character is located is indispensable, and there are at most 4 vertical units, forming single-character, double-character, three-character and four-character syllables respectively. like

They are single, double, three and four syllables of Tibetan.

的编码分别为：kyi、rjes、pcos、gsungs；没有元音的单字、双字、三字和四字音节：

的编码分别是bay、dam、bzhag、vphags。The coding rule of the syllable is: when the base word has a vowel, the coding of this syllable is as follows: pre-addition word, upper addition word, base word, lower addition word, vowel, back addition word, back addition word, each The Latin transliteration of the letter omits the letter a; when the base word has no vowel, the Latin transliteration of the base word cannot omit a, and the coding rules for other letters of this syllable are the same as those with vowels. Such as single, double, triple and quadruple syllables with vowels:

The codes are: kyi, rjes, pcos, gsungs; single-word, double-word, three-letter and four-letter syllables without vowels:

The codes are bay, dam, bzhag, vphags respectively.

Sanskrit is regarded as a single syllable, because Sanskrit is just superimposed letters, some superimposed layers as many as 7 layers.

的拉丁转写即编码依次是kkhi、kngM、kshAu、kEH、sgha。藏语词汇的拉丁转写是各音节的拉丁转写之间用空格隔开。藏语词汇的编码规则是：音节编码之间加空格。The Sanskrit encoding rules are: the encoding of Sanskrit with vowels is the Latin transliteration of each letter from top to bottom, omitting a, and finally the Latin transliteration of vowels; for Sanskrit without vowels, the order is still from top to bottom, The Latin transliteration of the last letter does not omit a, and the Latin transliteration of other letters omits a. such as Sanskrit

The Latin transliteration or coding of is kkhi, kngM, kshAu, kEH, sgha in sequence. The Latin transliteration of Tibetan vocabulary is separated by spaces between the Latin transliterations of each syllable. The coding rule of Tibetan vocabulary is: add spaces between syllable codes.

表示空格键，这就是本输入法中该词的输入码，其中包括5个空格键。Such as words: The Latin transliteration of is:

,in

Represent a space bar, which is the input code of this word in this input method, including 5 space bars.

As a perfection of the present invention, the input method of the present invention has the prompt function of candidate syllables and candidate words. That is, when the user enters one of the pre-addition, pre-addition and base characters of a syllable, the user is prompted for all candidate syllables with the input pre-addition, superposition or base character; when a syllable is entered, then a space is entered When entering the coded input of vocabulary, the user is prompted for all candidate vocabulary that includes the input syllable.

In Tibetan writing habits, the basic character of a syllable is the basic point of thinking, and the basic point of thinking about words is the basic character of each syllable. That is to say, when writing a syllable, people first think of the basic character of the syllable. In order to adapt to Tibetan thinking habits, the present invention has syllable base character codes, word base character codes and prompt functions in the input process.

The base word coding of syllable is: code with the base word of syllable, or begin to encode from base word; The input of base word encoding of word is: space interval is used between the base word encoding of each syllable, or each syllable begins to encode from base word .

as syllable The codes of the base characters are: b, j, zh, s; the codes starting from the base characters are bya, jes, zhag, sungs respectively.

When the input word does not exist in the input method dictionary, the user forms a new word. To enter a word: ,enter

, then select the first syllable of the word from the candidate window, and then select the second syllable to send the new word into the text area. Vocabulary memory is to store new words into the user's thesaurus, and when the user enters again, they will be directly listed in the candidate window.

(拉丁转写为：rtsod pa phyir bcos kyi gzhi)，本输入法需要输入该词中的11个字丁和5个音节点，第一个字丁

的拉丁转写是rtso所以需要4键输入，第二个字丁

以及其它的字母字丁

各需要2键，因此输入词

共需要按键32次。Existing input methods all use character coding as the input unit, such as the Latin input method, which is an input method that inputs the Latin transliteration of each character and converts it into a Tibetan character, a complete Western keyboard. To enter the word

(Latin transliteration is: rtsod pa phyir bcos kyi gzhi), this input method needs to input 11 characters and 5 syllable nodes in the word, the first character

The Latin transliteration is rtso, so it needs 4 keys to input, the second character D

and other alphabetic characters

Each requires 2 keys, so enter the word

A total of 32 key presses are required.

需要键入三次，输入

键入d和空格键，因此输入词

共需要按键29次。所以这种输入法不仅按键次数多，还要记忆藏文字母键盘编码。The Tibetan spelling input method is characterized in that the 30 Tibetan letters and 4 vowels correspond to the keys of the English keyboard. The number of superimposed layers of each character plus the space bar is the number of keystrokes for the character. . as input

Need to type three times, enter

Type d and space bar, so enter the word

A total of 29 key presses are required. Therefore, this input method not only has a large number of keystrokes, but also memorizes the Tibetan alphabet keyboard code.

Compared with the prior art, the input method involved in the present invention is easy to learn, easy to remember, fast and standardized, and its advantages are as follows:

1. The input method is fast and efficient

(拉丁转写为：rtsod paphyir bcos kyi gzhi)，本发明的输入法包括最后的键选，只需要12键。如果类似模式的词汇较多，最多加翻页键；藏文词汇以两三个音节者居多，所以越是长词，翻页的机会越少。加上用户组词功能，词汇的输入速度更是成倍增加。本发明的输入法经使用，输入效率提高1倍。Compared with some existing input methods, the present invention uses syllables as the input unit, making the input method fast and efficient. Enter the words mentioned above

(Latin transliteration is: rtsod paphyir bcos kyi gzhi), input method of the present invention comprises last key selection, only needs 12 keys. If there are many words with similar patterns, you can add a page-turning key at most; Tibetan words are mostly two or three syllables, so the longer the word, the less chance to turn the page. Coupled with the user's word formation function, the vocabulary input speed is doubled. After the input method of the present invention is used, the input efficiency is doubled.

2. The Latin transliteration input of the basic word is consistent with the thinking habits

The encoding rule of the present invention is based on the Latin transliteration of Tibetan traditional culture, without complex rules such as splitting, and without memorizing the key positions corresponding to Tibetan letters, Tibetan can be input by pressing the existing English keyboard, creating a natural input process. In addition, the Latin transliteration input method of the base character of the vocabulary is completely in line with the thinking habits of the Tibetan language.

3. The input process has the function of "orthographic", which solves the problem of standard use of syllables in Tibetan input

Since the syllables have strict combination rules, all standardized syllables are generated according to the rules, so that no wrong syllables will appear during the use of this input method, which plays the role of "orthographic".

4. Integrate Tibetan syllables, Sanskrit and vocabulary input

Words are composed of syllables, and syllables are composed of characters according to certain rules. The present invention regards the syllable with group word meaning as the basic unit of input, and the Latin transliteration of word is to use space interval between the Latin transliteration of each syllable, and the input of all syllables is continuous coding string, basic word coding string, One of the encoded strings starting with the base word, one of the first letters of the Latin transliteration of the base word; Sanskrit input is the Latin transliteration of the first letter, the Latin string starting with the first letter, the first letter of the Latin transliteration One of them; and the input of the vocabulary is one of the syllable base words separated by spaces, the Latin character string starting from the base word, and the first letter of the Latin transliteration of the base word.

5. Reduce the troubles brought to the inputter due to inconsistent input codes

Tibetan Latin transliteration is not restricted by the three major dialects (Weizang, Kang, Anduo) and domestic and foreign regions. The input method of the present invention can make Tibetan syllables, Sanskrit and words compatible input only with an English keyboard, greatly The amount of coding memory is reduced, as long as you can transcribe Tibetan and Latin, you can input it, which is easy to learn and remember.

6. Realize high-frequency foresight, dynamic adjustment, and word formation memory of Tibetan vocabulary input

The feature of this input method is the high-frequency foresight of the input, and the combination of static statistical results and dynamic usage, and dynamically adjusts the vocabulary frequency according to the user's usage, so as to meet the user's requirements; According to the entries of the input method dictionary, the user can Form words, and have the memory function of the user's word formation, so as to realize the user dictionary suitable for the user; according to the system input method dictionary and the user dictionary, the Tibetan input is more convenient and faster.

Detailed ways

Implement this input method solution through the following steps.

1. Establishment of syllable template library

Refer to Figures 1 and 2: Tibetan syllables are composed of seven components centered on the base character. Except for the base character, the other components are still syllables. There are strict combination rules for words, post-additions and post-additions.

Referring to Fig. 3: the present invention has generated standard syllable (single word, double word, three word and four word syllable) table according to Tibetan syllable combination rule, altogether 11022 standard Tibetan syllables; According to the Latin transliteration rule of Tibetan, design syllable The conversion program to Latin transliteration obtains the corresponding table of syllables and their Latin transliteration; Sanskrit has 3,740, and generates the correspondence table of Sanskrit and its Latin transliteration according to the Latin transliteration rules of Sanskrit. The file storage format for syllables and Devanagari and their Latin transliterations is:

Latin transliteration Several syllables of the same Latin transliteration separated by spaces and Sanskrit

This file is the syllable template library of this input scheme. The Latin transliteration codes and the Sanskrit Latin transliteration code table starting with the base character of the standard syllable for the input method are as follows:

a

aAbs

aAgs

aAms

a Angs

...

the b

bab

babs

bAbs

...

2. Establishment of input method dictionary

See Figure 3: According to the rules of Latin transliteration of Tibetan words, generate a correspondence table between Tibetan words and Latin transcriptions, or a correspondence table between Tibetan words and Latin transcriptions starting with basic characters, or a table of Latin transcriptions between Tibetan words and basic characters Write a correspondence table, and corpus-based vocabulary frequency statistics.

3. Input principle and input process

3.1 Input Principle

According to Fig. 3, it can be seen that firstly, a syllable library and an input method dictionary are established. According to the Latin transliteration of syllables or part of the Latin transliteration input starting with the base word, search the syllable library and perform matching processing; or match the Latin string starting with the base word or the first letter of the Latin transliteration of the base word separated by spaces in the input deal with. If the matching result is unique, only one item will be included in the candidate window. If there are more than 2 candidate words, they will be included in the candidate window according to the word frequency, and the user will determine and send them to the inner code text receiving area. If the input word does not exist in the dictionary, but consists of words and words, words and syllables, or syllables and syllables, then it can be selected for input and editing to form a new word, and the new word will be sent to the internal code text acceptance area and added The function of newly created words will be stored in the newly created user thesaurus. The storage structure of the user thesaurus is exactly the same as that of the input method dictionary. When these newly coined words are input again, they will be matched by searching the user thesaurus.

3.2 The input process of Tibetan letters, inverted characters, vowels, syllables, Sanskrit and vocabulary

(1) Tibetan letters and their corresponding key combinations are as follows:

ka kha ga nga ca cha ja nya ta tha da na pa pha ba ma tsa

tsha dza wa zha za va ya ra la la sha sa ha a i u e o

是击单键a；要输入4个元音

，只要分别击i、u、e、o键即可。To enter Tibetan letters , as long as you press the key combination kha, ga, nga, ca, cha, ja, nya and ta respectively, only letters

Is to click the single key a; to input 4 vowels

, just hit the i, u, e, o keys respectively.

(2) Anti-words, vowels and their corresponding key combinations are as follows:

Da Na SHa THa Ta E I I M O H

，只要分别击E、I、M、O、H键即可。To enter inverse , hit the combination keys SHa and THa respectively; to input vowels

, just hit the E, I, M, O, H keys respectively.

作为长元音时键入A。如要输入

，则击组合键bA。letter

Type A as a long vowel. To enter

, then press the key combination bA.

(3) Syllable input process: according to the Latin transliteration code input that the base word begins, its input process has automatic prompting function: when inputting the Latin transliteration of the base word of a syllable, prompting all syllables formed with this base word, this process follows Further input continuously adjusts the prompt results, and when input to a Latin transliteration of a syllable ends, the candidate window only lists syllables with the same Latin transliteration.

，其拉丁转写为ljo。当输入l时，提示以

为基字的所有可能的音节：

…；当输入到lj时，候选窗口列出的音节有

；当输入ljo时候选窗口只有一个音节

, whose Latin transliteration is ljo. When l is entered, the prompt ends with

All possible syllables for the base word:

...; when entered into lj, the syllables listed in the candidate window are

;When inputting ljo, the selected window has only one syllable

.

(4) Input of Sanskrit: input according to the Latin transliteration code that forms Sanskrit letters from top to bottom, and finally vowels. The input process has a prompt function like the input syllable: , all Sanskrit words formed with the first letter and all syllables with the letter as the syllable base are prompted. This process continuously adjusts the prompt results with further input. List Sanskrit and syllables of the same Latin transliteration.

的拉丁转写是NTHe。当输入N时，提示以

为第一个字母的梵文：

…这时就可以在候选出口选择输入；如果继续输入提示范围将不断缩小，到最后输入e时只有唯一的梵文

。To enter Sanskrit

The Latin transliteration of is NTHe. When N is entered, the prompt ends with

Sanskrit for the first letter:

…At this time, you can select input at the candidate exit; if you continue to input, the range of prompts will be continuously narrowed, and there is only the only Sanskrit when you finally input e

.

(5) Vocabulary input and fast input: the input of a word is the Latin transliteration string starting from the base word, and each base word Latin transliteration is separated by a space; the fast input of a word is to type each syllable base word Latin Transliterated initials, type spaces between letters. When inputting the Latin transliteration of the base character of the first syllable of a word, all words with the base character as the first syllable will be automatically prompted; when a space and the base character of the second syllable are input, the first All vocabulary for the base syllable and the second base syllable, and so on.

，可以输入基字开始的拉丁转写：to enter the word

, you can enter the Latin transliteration starting with the base word:

，也可以输入：

Indicates entered spaces, the latter being faster than the former.

3.3 User group word input

输入空格间隔的基字开始的拉丁转写：rls chen，则从候选窗口选择该词的第一个音节，再选择第二个音节便将新组词送入文本区。If the input word does not exist in the input method dictionary, a new word can be formed. To enter a word:

Enter the Latin transliteration starting with the base word separated by spaces: rls chen, then select the first syllable of the word from the candidate window, and then select the second syllable to send the new word into the text area.

3.4 Vocabulary memory

Vocabulary memory is to store new words into the user's thesaurus, and when the user enters it again, it will be listed directly in the candidate window. The prerequisite is that several words that form the new word exist in the dictionary.

The following Tibetan phrases are not in the dictionary: , when each syllable base character of inputting this word starts, the process of making words is the same as (3), except that the word could be obtained by 4 selections and sent into the text area. Because the four syllables that make up the phrase are also words and are in the input dictionary, when typing the Latin transliteration of the base word of the word again or only entering the first letter of the Latin transliteration of the base word of each syllable with spaces The first item in the selection window is the word.
