JPH0622029B2 - Method and device for inputting Chinese character symbols to terminal device - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a method for inputting Chinese character symbols to a terminal device according to the so-called superordinate concept of claim 1. The invention further relates to a device for carrying out this method.

2. Description of the Related Art It is already generally known to input Chinese characters using a keyboard of alphabet letters and using pinyin phonetic symbols. For this purpose, a kind of phonetic alphabet can be represented and 410 syllables associated with 6764 Chinese alphabet symbols can be used. As is clear from this, a large number of Chinese alphabets are pronounced the same (homonyms), and the assignment or correspondence of individual syllables to Chinese alphabets is very often ambiguous.

In addition, 6764 Chinese characters and symbols
It is also known to identify with a codeword that consists of one number and is uniquely associated with one Chinese character symbol. Therefore, for example, when transmitting a Chinese manuscript or text, it is possible to add a code word and transmit it. However, in that case, the sender is required to determine the relevant codeword for each Chinese character symbol, which is possible only with the aid of a comprehensive table or table.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a Chinese character symbol input method and apparatus in which a related Chinese character symbol is automatically obtained after a word is input using a phonetic symbol. .

Structure of the Invention According to the present invention, the above problem is solved by the structure described in what is called a characteristic part of claim 1.

Instead of associating each syllable with a Chinese character symbol, which is often quite ambiguous, the present invention provides a sequence or sequence of syllables corresponding to multiple words,
In many cases, it starts from the recognition that it can be uniquely associated with a Chinese character symbol string. Therefore, each syllable of the phonetic symbol is assigned a syllable identification value, and the word memory stores a number of Chinese words by a sequence of syllable identification values. Further, one ordinal value is stored in association with each syllable identification value, and this ordinal value determines how many Chinese character symbols among a large number of character symbols identified by one syllable identification value are targeted. Give instructions. For example, the word memory has 30
A sequence or sequence of 000-word syllable identification numbers and associated sequence numbers are stored. It has been found to be expedient to configure the word memory to have one dedicated storage area for syllable numbers greater than "1". In this way, the search process can be facilitated according to a predetermined order of syllable identification numbers and associated order values.

The syllable sequence or sequence is strictly ordered according to the syllable identification value, the syllable identification value is followed by the first syllable, then the identification value is followed by the second syllable, and so on. It is expedient to order so that the third syllable is located.

Perform an extraction test in the area of the corresponding syllable identification value, and determine, for each extraction test, if registration content exists, whether the registration content is included in the area before the extraction test or the area after the extraction test. Allows a search for a particular word to be performed particularly quickly.

Sequences or sequences of multiple syllables are uniquely
If it cannot be mapped to a string of character symbols, the first string of Chinese character symbols corresponding to the input syllable string is first displayed on the output device and depends on the operation of the first or second key. It is preferable to confirm that the syllable column is proper or display another syllable column.

If one or more syllables are contained in a long word as a sequence of Chinese character symbols, the syllable is identified by an additional input of the long word, and the long word is stored in word memory. It is also possible to identify the long word as long as it exists.

Treat idioms consisting of multiple words as if they were double syllable words, in order to be able to enter common expressions or very frequently used word sequences in a simple way, with separators instead of spaces between individual words. Advantageously, so that the word sequence can be searched in the word memory as well as in double syllable words.

The word memory is configured such that after input via the keyboard, the words are synthesized from the individual Chinese character symbols and automatically re-ordered in the word memory after activation of the corresponding additional command keys. Is advantageous.

In order to adapt the word memory to the user's vocabulary, enter the word to be erased through the keyboard and erase after activation of the key associated with the erase command, the sequence in the word memory is automatically after the erase. Advantageously, it is reset.

If the word does not exist in the word memory, on input the display will show a short sequence of letters and symbols corresponding to the part of the word you are looking for and a sequence of Chinese letters and symbols consisting of the most frequently used syllables. It is advantageous to generate a signal to display and inquire of the user whether to confirm this column or request another column.

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

In the apparatus shown in FIG. 1, the Chinese character symbols are the international standard keyboard of the Alfabet alphabet. It is entered using phonetic symbols. This device has 6674 encoded Chinese character and phonetic symbol generators ZG.
It has a storage device SP equipped with. Further, the storage device SP includes a word memory WS in which, for example, 30,000 Chinese words or words are encoded and stored. Furthermore, the device comprises a processing device VE and an output device, which preferably comprises a display device AE with a screen BS and / or a printer DR, which printer is configured as a matrix printer. The processing unit VE produces a code word CW for the computer system or transmission system for further processing of the input character symbols.

Chinese words are input using the phonetic symbols on the keyboard TA. In this case the syllables are also written together as in the currently used dictionaries. The end of a word is identified by entering a space or punctuation mark. In order to be able to check the input, the input data is displayed on the screen BS and / or of the display device.
Alternatively, it can be displayed on the printer DR. In this case, the display is in the form of an input phonetic symbol each corresponding to one Chinese character symbol and / or a Chinese character symbol corresponding to the internationally uniform code word CW.

After entering a word of characters, the characters are broken into individual syllables. This is done automatically by entering a separator after each syllable, such as the symbols "'" or "-", or by splitting into individual syllables.
The storage device SP is a memory SKS for syllable identification values.
And each of the 410 possible syllables is assigned a syllable identification value. Then, the search for one word is started in the same sequence as the syllable identification value in the word memory WS. The word memory WS stores 30,000 words by the syllable identification value. In this case, writing to the word memory WS is performed in the following ordered sequence. That is, first, in accordance with the number of Chinese characters of a word (word), that is, the number of syllables, the alphabetic character corresponding to the phonetic symbol of the first Chinese character, and then the second Chinese character. The alphabet corresponding to the phonetic symbol of the character and the alphabet corresponding to the phonetic symbol of the following Chinese character are respectively input corresponding to the syllable identification values.

Therefore, a search according to the sequence of Chinese character symbols corresponding to the input sequence of syllables can be performed on the ordered list of syllable identification values of the second syllable. The starting and ending addresses of this list are stored as a function of the number of syllables and the syllable identification value of the first syllable. For long words, the search is done within 100 milliseconds. If more than one sequence (column) of Chinese characters and symbols corresponding to the input syllable sequence is input to the word memory WS, this first column of Chinese characters and symbols is displayed. , Ask the user to confirm this or to enter the next appropriate sequence or sequence of Chinese character symbols. In the case of a word consisting of 2 syllables, almost 2% of the input words are polygraphs.
Ambiguity is very small when a word consists of three or more syllables, so that the search ends very quickly.

If a word or a word is not already stored in the word memory WS, this word is input as a sequence of symbols. In this case, the symbol string is stored in a small unselected area of the word memory WS until it is correctly arranged in the activation process of the next word memory WS. The word memory WS can thus be adapted to the user's vocabulary capacity.

The word memory WS thus stores the syllable identification value and the associated ordinal value. Therefore, 2 bytes are required for each Chinese character symbol. 3 on average
A storage capacity of 180 kilobytes is required for 30,000 words of one character. The word memory WS is configured such that a unique storage area is provided for each syllable number larger than "1" so that a quick search can be performed. The individual inputs or registrations of the sequence of syllables are strictly ordered according to the syllable identification value. That is, according to the syllable identification value of the first syllable, then the syllable identification value of the second syllable, and then the syllable identification value of the third syllable. Be done.

The search for a word in the word memory WS is
Is it carried out in the extraction test in the area of the corresponding syllable identification value, in which case the extraction test is performed in the center of the remaining search area, and for each extraction test, is it registered in the area before or after the extraction test? Whether or not the evaluation is performed is performed. As a result, each extraction test is divided into the remaining search areas, and thus the registered content is detected from the gradually decreasing area.

The association of the syllable identification value and the ordered value with the code word CW is performed using the code word memory CWS also included in the memory SP. Code word C
W is also sent to the symbol generator ZG for displaying the character symbol on the output device.

By using the keyboard TA to enter Chinese characters by phonetic characters, the processor VE can automatically break the words into individual syllables. It is also possible to separate words on a syllable basis, for example by inserting the symbols "'" or "-". The processing unit VE uses the memory SKS to determine the syllable identification value associated with each syllable.

Also, in order to be able to enter frequently used word sequences of many words, i.e. idioms, such idioms are treated like double syllable words, instead of spaces between individual words. Another separate signal is input to, for example, the symbol "-", to indicate that this word sequence should be searched for in a word memory in a manner similar to a double syllable word.

The table below shows the correspondence or correlation list between the 410 syllables and the corresponding syllable numbers.

For example, when inputting the word "babaocai", the word is divided into syllables "ba", "boa" and "cai", and identification values 6, 10 and 23 are assigned to these syllables.

The processor VE uses the word memory WS to determine, based on the sequence of syllable identification values, an ordinal value that represents how many Chinese character symbols identified by the syllable identification value belong to the word. Subsequently, the processing device VE
The code word memory CWS is used to find the code word CW associated with the Chinese character symbol. This code word CW is, for example, input to a computer for the purpose of another processing or transmitted to another terminal device.

FIG. 2 shows a part of the correspondence table stored in the word memory WS for associating the code word CW and the syllable with the Chinese character symbols. The complete correspondence table shows the correspondence between 6764 Chinese characters and 410 syllables and corresponding codewords CW.

FIG. 3 shows a part of the correspondence table stored in the word memory WS for the Chinese character symbols corresponding to the two syllable words input using the phonetic symbols. For example,
When the word "aci" is entered, the processor uses the memory SKS to determine the syllable numbers "1" and "49" corresponding to the syllables "a" and "ci". A word memory WS in which all syllable words are stored is used to determine how many character symbols corresponding to each syllable are included in the input word. The ordinal numbers OZ each start with a number "0", and in the present case an ordinal number "1" is determined for the syllable "a" in the word memory WS, which has the code word CW "1602". The second of the syllable "a"
Means the character symbol. The associated Chinese character symbol CHZ is also shown in FIG. In a corresponding manner, the word memory WS has an ordinal value OZ of "9" and a syllable identification value "4" with the code word CW "2044".
It indicates that it is the character symbol of the 10th number of the syllable “ci” of “9”. Similarly, the syllable identification value SK and the sequence value O for the input words "adou", "afi" and "aiai"
Z and code word CW and Chinese character symbol CHZ
Is required. In association with the word "aiai", the table recognizes that this word is a word having a syllable with a syllable identification number "2". From the word memory WS, this word is the character symbol of the sequence number "5", ie
It is detected that it is represented by the sixth character symbol of the syllable “ai” of the code word “1608”, and the corresponding character symbol is displayed.

FIG. 4 shows a syllable identification value SK, a sequence value OZ, a code word CW and a Chinese character symbol CHZ for a plurality of three syllable words stored in the word memory WS.
It is shown. For example, when the word "aihaozai" is entered, the processing devices are "2", "115" and "388".
The syllable identification value SK is obtained from Word memory WS
Assigns the sequence values "11", "5" and "0" to this word, and the code word memory CWS
The code words "1614", "2635" and "5358" are obtained from the code words. Then, based on these code words CW, the Chinese character symbol CHZ is output from the code generator ZG to the output device.

As shown in FIG. 2, when only one syllable is input, there are many correspondences of character symbols to this syllable. FIG. 2 shows only the Chinese character symbol CHZ which is most frequently used for the syllables "a" and "ai". As code word CW ', another code word is shown which also corresponds to syllables "a" and "ai", but is relatively unused. There are numerous possibilities to find the desired letter symbol based on the syllables represented by the phonetic symbols. For example, in the example shown in FIG. 5, it is assumed that a particular letter symbol corresponding to the syllable "ba" is required for the entry of a word. When only the phonetic symbol "ba" is input, the output device, for example, the display screen B of the display device AE.
First, in S, the code word CW "1649" of the character symbol corresponding to the syllable "ba" with the highest frequency is shown.
However, since the characters and symbols shown at the top of FIG. 5 are required, the displayed characters and symbols are not accepted and the user is relatively infrequently used. Activate the "Search" key until the desired letter symbol with CW "1648" appears. Note that the desired character is accepted by actuating the "confirm" key. Although the character symbols are shown side by side in FIG. 5,
On the picture screen BS, these character symbols appear sequentially in time.

FIG. 6 shows another example of finding the desired letter symbol corresponding to the syllable "ba" very quickly. The syllable "ba" is additionally provided with the number "3", which indicates that this syllable is to be pronounced in the third note, to the user the code word CW "1649". And only the two letter symbols with "1648" are shown.

FIG. 7 shows another example of finding a desired character symbol very quickly. The syllable "ba" is shown to have a final sign "ge" separated by a "#" mark, in which case the code word CW is immediately generated.
The desired letter symbol with "1648" is displayed. When a character symbol of the syllable “ba” and a character symbol having the final sound symbol “ti” is desired, this character is separated and input by the “#” mark, and is sequentially input to the image screen BS in time. , Code words CW "1638" to "164"
Four letter symbols with "9" appear.

When searching for a single syllable or a double syllable word included as a symbol string in a long phrase, it is realized by additionally adding a known long word, for example, by a separator such as "<". In the example shown in FIG. 8, the syllable “ba” contained in the word “baxin” is retrieved and the user is given the code words “1648” and “16”.
The letter symbol with "49" is shown. Word "bachang"
When searching for a syllable "ba" that is also included in, the user is shown only the syllable having the codeword CW "1648". In a similar fashion, for example, the word "bab
You can ask for the letter symbol "bao" that appears in "ao", or you can ask for the letter symbol "jiao" contained in the word "bajiaoshan".

The word memory WS can be adapted to the needs of the user by adding another word or erasing unnecessary words. Use the keyboard T to enter words
The words are synthesized from the individual symbols while interacting with the output device via A, and then in response to an additional command, the order in the word memory SW is automatically set again in response to the additional items.

To erase a word in the word memory WS, the word is input via the keyboard TA and an erase command is issued to erase the word. The order in the word memory WS is automatically reset as the registered items are deleted.

If the word cannot be found in the word memory WS,
The user is presented with a short symbol sequence corresponding to the part of the word he is looking for on the output device and a sequence of the most frequently used homonyms for the remaining syllables. If there is a relevant word, the user is required to confirm the symbol string or, if it does not exist, to continue the search.

Fig. 9 shows the idiomatic expression "aibing bi she" that consists of multiple words that are treated in the same way as in the case of Chinese words with multiple syllables.
ng ”is shown. Instead of leaving a space between words, another separator, eg "-", is filled in and the word memory WS determines the relevant syllable of the word,
The codeword memory CWS then assigns codewords to the syllable in the same manner as for individual words.
