Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to a Japanese input processing method, in particular, a Japanese language input processing method that inputs a kana character string, converts it into kana-kanji word by word, and creates Japanese that is a mixture of kanji and kana. This relates to input processing methods.

(2) Prior Art and Problems In general, in Japanese input devices that perform kana-kanji conversion on a word-by-word basis, after inputting a kana character string, it is necessary to either convert the words of the kana character string into kanji, or
The user instructs whether to leave it as kana or leave it as kana by pressing the "conversion" key or "no conversion" key on the keyboard.

FIG. 1 shows an example of kana-kanji conversion for conventional word-by-word input. In the figure, 1 represents a Japanese input device, 2 represents input data, and 3 represents output data. For example, if the user presses the kana character keys on the keyboard sequentially,
When you press "ho", "n", and "go", "Nihongo" is output and displayed. "Convert" here
When the key is pressed, the kanji corresponding to the kana character string ``Nihongo'' is extracted from the word dictionary, converted to kanji ``Japanese,'' and output. When the "no conversion" key is pressed after the character key for "no", "no" is displayed as a kana and is excluded from conversion.
By pressing each character key for "niyuuriyoku" and the "conversion" key, the kanji "input" is output.
That is, the Japanese input device 1 receives input data 2 and outputs output data 3.

In the above-mentioned conventional method, the following problems occurred because the "conversion" operation had to be performed for each word registered in the word dictionary.

FIG. 2 shows a diagram explaining the problems of the conventional method. For example, it is assumed that the word dictionary 6 of the word dictionary memory 5 has words as shown in the heading section 7 registered therein. The kanji word section 8 stores kanji codes corresponding to the headings in the heading section 7.

Here, as shown in input data 2-1, it is assumed that the user keys in "Nihongo ni Yuuriyoku Hoshiki" beyond the word break and finally presses the "Convert" key. Since there is no corresponding word in the word dictionary 6, the conversion fails and the result is output data 3-
1 remains as kana. The cursor 4 is displayed to indicate the next character after the last character "ki". If you wish to make corrections, select "Cancel" as input data 2-2.
key is pressed to return the cursor 4 to the beginning as shown in output data 3-2, and by pressing the cursor movement key shown in input data 2-3, output data 3
Move the cursor 4 to the position next to "Nihongo" as shown in -3. If a "conversion" instruction is given as input data 2-4, the word dictionary 6 is referred to again, and the kanji "Japanese" is output as output data 3-4. As a result of this conversion, the initially input kana character string "Niyuri Yoku Hoshiki" becomes invalid, so the input data 2-5 and 2-
Input data as shown in 6 and output data 3-
5. It is necessary to output as shown in 3-6.

As described above, the conventional system has a problem in that when a user attempts to input a multi-word character string thinking that it is one word, most of the input character string is wasted. However, in normal character input, users generally try to avoid pressing the "convert" key unnecessarily, and if they try to convert a short string of characters, the probability of homonyms increases, so they try to avoid using characters as long as possible. Attempt to convert columns. Therefore, the above operations occur frequently,
This caused poor operability.

(3) Purpose of the Invention The purpose of the present invention is to solve the above-mentioned problems, improve operability, and reduce the burden on the user so that input can be performed efficiently.

(4) Structure of the Invention In order to achieve the above object, the present invention always searches a word dictionary for words whose headings are the previously input kana character strings each time a kana character is input. If one word can be determined,
At that point, the word is automatically displayed. That is, the Japanese input processing method of the present invention is provided with a word dictionary having a header part of a kana character string and a kanji word part in which a kanji code corresponding to the kana character string is stored. In the Japanese input processing method that refers to a word dictionary and converts each word into kanji and displays it, the word dictionary is searched each time each kana character is input, and a candidate word with the input kana character string as a heading is selected. a determining means for determining whether the candidate word selected by the retrieving means has been determined to be one; It is characterized in that it is equipped with a display means for converting and displaying kanji as a conversion target, and that automatic kana-kanji conversion is performed on a word-by-word basis. Embodiments of the present invention will be described below with reference to the drawings.

(5) Embodiment of the invention FIG. 3 shows the configuration of an embodiment of the invention. In the figure,
1 is a Japanese input device, 5 is a word dictionary memory, 6 is a word dictionary, 7 is a heading section, 8 is a kanji word section, 9 is a keyboard, 10 is an input pointer, 11 is an input buffer, 12 is a control section, 13 is a Word dictionary management department,
14 is a search unit, 15 is a first candidate pointer, 16 is a final candidate pointer, 17 is a determination unit, 18 is a display processing unit, 19 is a Japanese text memory, 20 is a display, and 21 and 22 are external storage devices.

The Japanese input device 1 inputs Japanese data such as kana character strings from the keyboard 9, performs kana-kanji conversion according to the word dictionary 6, and displays the processing results on the display 20.
This is a device that stores data in an external storage device 21 such as a disk. The keyboard 9 used for input is provided with various character keys as well as a "conversion" key, a "no conversion" key, a cursor movement key, etc., as in the past. The input character string code input from the keyboard 9 is stored in the input buffer 11. The input pointer 10 points to the position in the input buffer 11 where the next input character data is to be stored, and the data from the beginning of the input buffer 11 to the point before the input pointer 10 is This is the word data currently being processed.
This input pointer 10 is initialized by an automatic conversion process, a ``conversion'' key, a ``no conversion'' key, a ``cancel'' key, etc., and is returned to point to the beginning of the input buffer 11. The input pointer 10 is also updated by pressing a cursor movement key. In normal character input, the character is moved one character to the right for each character input.

The control unit 12 controls the entire Japanese input device 1, and controls starting the search unit 14 of the word dictionary management unit 13 and the display processing unit 18 for each character input. .

The word dictionary management unit 13 manages the word dictionary 6 and stores the word dictionary 6 from an external storage device 22 such as a flexible disk to the word dictionary memory 5.
It reads the file and performs processing such as searching and conversion. The word dictionary 6 consists of a heading section 7 and a kanji word section 8, and the heading section 7 stores headings corresponding to input character string codes of words registered in the word dictionary 6. The kanji word section 8 stores kanji codes into which input character string codes are to be converted, corresponding to each heading. For words with homophones and allographs, a plurality of Kanji codes are assigned to one heading, and in this case, the Kanji codes are arranged, for example, in order of appearance frequency.

The search unit 14 searches the word dictionary 6 each time each character input from the control unit 12 is transferred, and points the range of candidate words using the first candidate pointer 15 and the final candidate pointer 16. I do. In the initial state, the first candidate pointer 15 and the final candidate pointer 16 are set to point to the beginning and end of the word dictionary 6, respectively.
Every time one character is input, for example, if the character "ni" is input first, the first candidate pointer 1
5 is made to point to the position of "ni/load" in the word dictionary 16, and the final candidate pointer 16 is made to point to the position of the last word starting with "ni". If "ho" is subsequently input, the first candidate pointer 15 is updated to point to "Japan" and the final candidate pointer 16 is updated to point to "Japanese."

The determination unit 17 determines whether the content of the first candidate pointer 15 and the content of the final candidate pointer 16 match, and if they match, that is, when the candidate words become one, the determination unit 17 determines the kanji code of the word. A process of reading out the kanji word part 8 and transferring it to the control part 12 is performed.

The control unit 12 transfers the words converted into kanji to the display processing unit 18, and the display processing unit 18 writes them into the Japanese text memory 19. The words in the Japanese text memory will be displayed on the display 20. It is also output to the external storage device 21 if necessary.

In addition, processing of "conversion" key and "no conversion" key,
Since the cancellation processing, cursor movement processing, and other general editing processing are the same as those of the prior art, their explanations will be omitted.

Next, the Kana-Kanji conversion process according to the present invention will be described, taking as an example the case where the character string "Japanese input method" is input, similar to the conventional example described in FIG. 2.

FIG. 4 shows an example of kana-kanji conversion according to the present invention. Below are the input numbers shown in Figure 4.
The explanation will be given in the following order.

In the initial state, the input pointer 10 points to the beginning of the input buffer 11, and the input pointer 10 points to the beginning of the input buffer 11.
1 is an empty state. The first candidate pointer 15 points to the beginning of the word dictionary 6, and the final candidate pointer 1
6 indicates the end of the word dictionary 6. In this state, when the character "ni" is input from the keyboard 9, the code for "ni" is stored in the input buffer 11, and the input pointer 10 is made to point to the next position. The control unit 12 transfers the code of “ni” to the search unit 14. The search unit 14 searches the word dictionary 6 for words with headings starting with "ni". The words searched here will be called candidate words. A first candidate pointer 15 points to the beginning of the candidate word "ni/load", and a final candidate pointer 16 points to the last candidate word. Since there are a plurality of candidate words starting with "ni", the determination unit 17 notifies the control unit 12 of this fact. The control unit 12 transfers the kana character code for “ni” to the display processing unit 18, and the display processing unit 18 stores it in the Japanese text memory 19. Therefore, the input character "ni" will be displayed as is.

Next, when "ho" is input, the control section 12 similarly transfers the character "ho" to the search section 14. The search unit 14 searches for words starting with "niho" from among the candidate words indicated by the first candidate pointer 15 and the final candidate pointer 16. The first candidate pointer 16 will be updated to point to "Nihon" and the final candidate pointer 16 will be updated to point to "Nihonjin." Since there are still multiple candidate words, the determination unit 17 notifies the control unit 12 of this fact and selects the kana character "niho".
will be instructed.

Similarly, in response to the input of “n”, the search unit 14
Search for words starting with "nihon". The first candidate pointer and the final candidate pointer 16 are not updated and "Nihon" is displayed.

If "go" is entered here, "Nihongo" is displayed.
Since there is only one candidate word starting with "Japanese", the contents of the first candidate pointer 15 and the contents of the final candidate pointer 16 match. If the determining unit 17 detects that the number of candidate words is reduced to one, it transfers the kanji code of the candidate word “Japanese” to the control unit 12. The control unit 12 transfers the kanji code to the display processing unit 18, and the kanji for "Japanese" is displayed instead of "Nihon". The input pointer 10, first candidate pointer 15, and final candidate pointer 16 are returned to their initial states.

~ Then press “ni” from keyboard 9,
``Yu'', ``U'', . . . are input, but a search is similarly performed each time each character is input, and ``Input'' and ``Method'' are output as shown in FIG.

In the above embodiment, when a character string that is not in the word dictionary 6 is input, such as "Nihonshiyu", for example, when it is found that it is not in the word dictionary 6, the character string is displayed in kana as is. Even though only one heading was decided for the candidate word,
If multiple kanji codes are associated with homophones, for example, output them in order of frequency of appearance,
It is made to switch by the "conversion" key.

Note that, for example, a mode instruction key may be provided so that the user can select either the normal mode or the automatic conversion mode. When the normal mode is instructed, the search request from the control unit 12 to the word dictionary management unit 13 in FIG. 3 is not made every time a character is input, but only when the "convert" key is pressed. , the conventional conversion process is performed, and when the automatic conversion mode is instructed, the conversion process according to the present invention is performed. In this way, it is possible to provide versatility while maintaining operational compatibility with conventional systems.

(6) Effects of the Invention As explained above, according to the present invention, when one candidate word is determined, the converted word is automatically displayed, so the user can input data beyond the word break. This eliminates the need for unnecessary input. In particular, when inputting compound words, it can be converted to kanji without having to be conscious of the boundaries between words, greatly improving operability.
