Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for inputting Chinese character symbols into a terminal device according to the general concept of claim 1. Furthermore, the invention relates to a device for carrying out this method.

BACKGROUND OF THE INVENTION It is already generally known to input Chinese characters (referred to as Chinese characters) in the form of words converted into Pinyin phonetic symbols using key dates.

During phonetic transcription, syllables similar to phonetic alphabets are entered as a series of alphabetic characters.

Chinese characters are composed of syllables consisting of an initial sound and a long sound. There are approximately 410 different syllables, each formed from 25 possible initial sounds and 34 possible long sounds. In Chinese, each syllable is represented by one letter symbol among a number of letter symbols (homonyms) associated with the syllable. A word is thus a sequence or string of one or more letter symbols, a sequence or string of one or more syllables.

It is conceivable to input Chinese character symbols using a key that is divided into two planes, with the initial sound written on one plane and the long sound written on the other plane. In this case, since the starting sound and the long sound are input alternately, switching from one to the other can be performed automatically. No difficulty arises in the decomposition of words into syllables, since the seeds can be separated by a single keystroke on the screen. This is because each input of one syllable requires two keyings.

On the other hand, when entering Chinese character symbols using phonetic characters using the customary international standard keyboard for alphabetic characters, it is impossible to simply break down words into individual syllables. . This is because the initial sound consists of zero or two letters, and the long sound consists of four or four letters.

OBJECTS OF THE INVENTION It is therefore an object of the invention to provide a method and a device that makes it possible to automatically divide Chinese words input using phonetic characters into a number of syllables. be.

According to the present invention, the above problem is solved by a method having the structure described in the so-called characteristic part of claim 1.

The method of the present invention has the following advantages. That is, the currently commonly used international standard keyboard can be used to input Chinese characters and symbols without modification, and the advantage is that inputting does not require a large operational cost.

In order to avoid ambiguity when decomposing words into syllables, it is expedient to insert separators where ambiguity occurs. Examples of this type of separation symbol include the symbol “
It can be IJ or the symbol "-". For post-processing, it is advantageous to assign a syllable identification number to each syllable and convert the word into a unique sequence of syllable identification numbers.

It is expedient for the syllable identification numbers to correspond to the syllables appearing in alphabetical order.

An advantageous device for implementing the method of the invention provides a memory in which all the syllables used are stored, and a control device for comparing after each entry of a symbol with the syllables stored in said memory. The method is characterized in that the word is checked to see if it is uniquely recognized as a syllable, and if it is not uniquely recognized, the word is decomposed into a syllable by taking into account the symbol that follows it.

It is expedient to configure the control device in such a way that after inputting a separator symbol, the syllable immediately preceding it is completed independently of the following character.

In the memory, a syllable identification symbol is assigned to the syllable for post-processing, and the syllable's unique existence recognition radius control device reads out the associated 7 rubble identification symbol from the memory.

The syllable identification numbers stored in memory correspond to the alphabetical order of the syllables used.

EXAMPLES Hereinafter, the method of the present invention and an apparatus for carrying out the method will be described in detail with reference to the accompanying drawings.

The device shown in Figure 1 is a conventional international standard keypad with keys for inputting alphabetic characters and for inputting numbers. A key configured as a -do is provided with a -do TA. The key date TA is connected to the control device ST. Preferably, this control device consists of one or more microcomputers. A memory SP is connected to the control device ST, and in this memory SP are stored Chinese syllables represented by phonetic symbols and encoded in binary. Furthermore, in the memory SP,
A syllable identification value is assigned to the syllable. This syllable identification number corresponds to the alphabetical order of the associated 7 rubles. A display device AE with a display screen BS is further connected to the control device ST, and furthermore a printer DR can be connected thereto. Finally, a processing device VE is connected to the control device and is supplied with the syllable identification value.

This processing device VE, together with the above-mentioned elements, constitutes a text input device, a printing or recording device, a computer, or a communication terminal device connected to the transmission line FL. In particular, the processing device VE is provided with a device for correlating syllables to Chinese characters. This is because each syllable can correspond to multiple Chinese characters pronounced in the same way, or at least expressed in the same phonetic symbol. ,pinyin(
Pinyin) is entered using phonetic symbols, and the control device ST automatically breaks down the entered word into individual syllables using the memo IJ SP and assigns a syllable identification value to the syllables, and the processing device Supply to VE.

For monitoring purposes, the input words and/or syllables and/or syllable identification numbers and/or the corresponding Chinese character symbols can be output to the display screen BS or to the printer DR.

Each syllable has 25 possible onsets and 34 possible entanglements (
The initial sound is formed from O or two letters, while the entanglement can be represented by O or four letters. Using the control device ST and the memory SP, the corresponding syllables are automatically determined for the input word, so each input character string is stored in the memory S.
When the syllable is uniquely recognized by comparing it with the seven verbs stored in P, the syllable is assigned a syllable identification value that is also stored, and is supplied to the processing device VE. The syllable under consideration always corresponds to an input character that can correspond to the syllable under consideration as well as the following syllable.

In the memory SP, the syllables are stored in correspondence with their alphabetical order, and each syllable is assigned a numerical value from "1" to r410J in increasing order. The correspondence between syllable identification numbers and syllables is briefly shown in Table 1, and conversely, the correspondence between syllables and syllable identification numbers is shown in Table 2.

For example, by phonetic transformation the Chinese word rbabaoc
When ai J is input, the control device ST inputs the letter “b”
After inputting , it is checked whether one complete syllable exists. According to the correspondence lists in Tables 1 and 2, the character rJ does not form a syllable, so after inputting the next character "a", it is again determined whether one syllable can be uniquely recognized. In the case of □ in this example, there is no syllable. This is because although the syllable "ba" is the syllable stored at the address with syllable identification value 6, it can be followed by other characters, so this syllable "rba"
is simply Cyrano #rbaiJ, rbanJ, r
bang't.

or rbao”. Only after the input of the next letter rJ does the control device ST identify the first syllable rbaJ. This is because simple rbaJ does not exist in the correspondence table of memory SP. Therefore, this syllable "ba" is identified as a complete syllable, and a syllable identification value "6" is assigned. Next, when the letter ``a'' is entered after the letter ``b'', it is again determined whether this syllable is complete or not; You have to wait for the character □. When the character "0" is input as the subsequent character, the control device recognizes the syllable rbao4 as a complete syllable.

This is because no other syllable starting with rbaoJ is stored in the correspondence table of memory SP. Therefore, this syllable is completed here, and the syllable identification number "1o" is assigned according to the correspondence table of Table 1 or 2. No syllable is recognized after the next character "C" is input, and no syllable is uniquely recognized after the next character "a" is input.

Because the syllables ``RCA'', ``RCAI'', RC
an”.

This is because it can belong to either rcangJ or rcaoJ. For the first time after entering the last letter rJ, the syllable rc
aJ is uniquely recognized and assigned a syllable identification number "23" according to the correspondence table.

In the Table 16 correspondence list, the syllables are entered in alphabetical order and are assigned numerical values in increasing order from "1" to r410J. In the correspondence table of Table 2, long sounds starting with vowels are entered in the first column, and related syllable identification values are entered in the second column. Further, in the first column, the first sound of the syllable that follows the partial syllable written in the tenth column is written. At the intersection, the syllable identification value of the syllable starting with the initial sound of the first column and ending with the long note written in the column is written.

In Table 2, the column and the value rO at the intersection of the columns
J means that there is no corresponding syllable. For example, the syllables rbeJ or rcei'' and the syllables rmue'' or rzueJ are absent. word or word rbabaocajl and word rb
The syllables that appear when inputting ``anama'' and the associated syllable identification numbers are shown in large frames in Tables 1 and 2.

When inputting the word or word rbanamaJ, first rJ is inputted, and then raJ is inputted, in a manner corresponding to the inputting of the word "babaocai J."

After inputting the character "ba", the syllable cannot be uniquely identified in this case either, so the complete syllable is recognized only after inputting the character rnJ, and the syllable identification number is "8".
is supplied to the processing device VE. After inputting the letter "a", the next syllable cannot be uniquely recognized. letter"
Only after inputting "m" is the character "a" identified as a complete syllable and assigned the syllable identification number "1". This is because there is no syllable ram in the memory SP. Similarly, after inputting the character "ma" and the space following it, the syllable "rma" is recognized and the syllable identification number 191 is assigned.

As is clear from the correspondence list in Table 1, the word rban
amaJ karba'namaJ or rba-nam
a”, this word rbana
"ma" is the identification number r6J, r210J and r19
1J with shirafuru rba'', rna'', r
There is a possibility that it will be divided into "ma". However, according to the invention, letters that can correspond to the syllable under consideration as well as the next syllable are always taken to be related to the syllable currently under consideration, so that other correlation or correspondence risks may arise. If so, you must enter a special separator. Such a separator is
For example, there is the symbol "'" or the symbol "-", so even in such special cases, unambiguous decomposition by syllable is possible.

Since each syllable as a phonetic symbol corresponds to a plurality of Chinese characters, it is not so easy to associate syllables with Chinese characters. For example, there are 18 different letters for the syllable I"baj, and 17 each for the syllables rboaJ and rcai".
There are 1 and 11 characters. The selection of the corresponding character then takes place automatically in the manner described in the patent application of the same date. For this purpose, a word list is used, in which, for example, 30,000 Chinese words or terms are stored with syllable identification numbers, and in which a symbol relating to the versatility of each syllable is recorded.

In this case, each symbol is assigned a four-digit numerical value that identifies the corresponding Chinese character. In this way, the Chinese characters of the input word can be displayed on the image screen BS of the display device AE or on the printer DR. When transmitting text or manuscripts, four-digit numerical values or syllable identification numerical values associated with characters are transmitted via a transmission line FL connected to the processing device VE. In the case of transmitting syllable identification numbers, a prerequisite is that the receiving device be able to associate Chinese characters with syllable identification numbers using a word memory.

In Figure 2, the word or word rbabaoca i

The Chinese characters obtained using rbanamaJ and rba'namaJ as well as associated nosyllabic identification numbers and word memory are shown.
