JPH0677252B2 - Japanese data input processor - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a Japanese text data input device such as a personal computer or a word processor, and particularly to a Japanese text data input processing suitable for processing handwritten character input data. Regarding the device.

[Conventional technology]

A keyboard device has been widely used as a data input device as a man-machine interface for data processing devices such as a personal computer (personal computer) and a word processor (word processor). Improvement of functions of the device and tablet device,
As cost reduction advances, the use of handwritten character data input devices is becoming more common.

By the way, using a conventional handwritten character data input device, as a method of inputting kanji kana alternate writing Japanese,
The following two methods are mainly known.

All kana characters are entered and then converted internally into kanji kana mixed writing. In addition, in this kana character input,
Includes Romaji input kana character conversion.

From the beginning, enter as it is as a kanji kana cross-written Japanese sentence.

Note that, as a device related to this kind of device, for example,
The disclosures of JP-A-57-6151 and JP-A-57-19471 can be mentioned.

[Problems to be Solved by the Invention]

The prior art described above does not give consideration to the degree of freedom of character selection at the time of input, and has a problem in input efficiency.

In other words, in data input processing using a handwritten character data input device, unlike the case of inputting data using a keyboard device, there is not always an objective in terms of efficiency between Kana and Kanji input operations. There is a possibility that it may be determined by the operator's individual differences, and therefore, in the above-mentioned conventional technique, in the method of (1), characters are written in Kanji rather than Kana. You must always write in kana, even if it is more efficient, while
In the above method, even in complicated Kanji, all necessary characters must be written in Kanji, and in the end it is impossible to make a preferable choice depending on the case, and it is difficult to always obtain the best result. It will be.

It is an object of the present invention to provide a Japanese text data input processing device capable of easily obtaining an efficient input operation when handwriting a Japanese text.

[Means for Solving the Problems]

The above object can be achieved by converting a kanji character into a kana character when the kanji character exists in the input character string, converting the kanji character into a kana character string, and then performing a kana → kanji name interchange sentence exchange.

[Action]

The character string input from the character input means is stored in the character storage means, and by some means, the kana-to-Japanese sentence conversion means converts it into a kanji-kana crossover sentence. Among the characters stored in the character accumulating means, the kanji is converted into a kana by using the character storage means to form a character string that does not include the kanji, and then converted into a kanji kana alternate sentence by the kana-to-Japanese conversion means.

This allows the operator to enter kanji and kana in any form when handwriting a Japanese sentence.
It is possible to input Japanese characters equivalent to the case where all kana and kana kana sentences are converted to kanji and kana kanji, and it is possible for each operator to input kanji and kana kanji in the most easy-to-write form. , Input can be done efficiently.

Here, when performing kanji-to-kana conversion, if a kanji having multiple readings is selected and converted into a kana by not selecting the reading that the operator does not intend, it will not be converted into an appropriate kanji kana interchange sentence.
To solve this, if the original position of the kanji is not included in the appropriate position in the result converted into the kanji kana crossover sentence, select another reading of the kanji and then convert it again from kanji to kana. , Kana → Kanji Kana interchange sentence conversion is performed, and this is repeated until an appropriate conversion result is obtained.

Also, when performing a kana to kanji kana crossover sentence conversion, even if a homonym opposition is selected, or when bunsetsu segmentation is automatically determined when bunsetsu segmentation is performed at the wrong position, the appropriate position of the conversion result Will not include the original kanji. In this case, in the Kana to Kanji Kana conversion sentence conversion, select the one that contains the original Kanji from the homonym opposition, or change the punctuation method until the original Kanji is included. , By repeating the conversion, a more appropriate conversion result can be obtained.

〔Example〕

Hereinafter, regarding the Japanese data input processing device according to the present invention,
This will be described in detail with reference to the illustrated embodiment.

FIG. 1 shows an embodiment of the present invention. In FIG. 1, reference numeral 1 is a position coordinate detecting means such as a digitizer, and 2 is an arithmetic processing device such as a computer. It is detected as position coordinates for changes. The handwritten character recognizing means 3 regards the temporal change of the position coordinates as a motion of a pen or the like, matches the pattern of the motion with the character pattern stored in the character recognition dictionary 4, and recognizes it as a specific character. Here, the handwritten character recognizing means 3 has a function of recognizing numbers, English characters, kana, and kanji in a predetermined range, and further can recognize a specific operation for instructing execution of a predetermined process. Is configured. On the other hand, when creating a document, the operator is instructed to input a character string by using a combination of characters that is easy to write, regardless of the final notation of the document. Therefore, these position coordinate detecting means 1
The handwritten character recognition means 3 and the character recognition dictionary 4 constitute a data input means described later.

Each of the handwritten characters is 1 by the handwritten character recognition means 3.
Characters whose recognition results are recognized as one character each are sequentially stored in the input character storage means 5.

The characters stored in the input character storage means 5 are taken out at every certain moment, and the kanji → kana conversion means 6 and kana →
The Japanese sentence converting means 8 converts the sentence into an appropriate kanji kana intersection sentence. Here, there are various possible triggers for starting the conversion, but in the present embodiment, when the operator performs a specific operation on the position coordinate detection means 1 which means the start of the conversion. Is configured to be.

The document editing unit 10 receives the converted Kanji / Kana alternation sentence, incorporates it into the document, displays the document on the display unit 11, and at the same time, the operator operates the position coordinate detection unit 1
Edit the document according to a specific operation that means editing, such as deleting characters or moving a sentence, and then edit the document that is being edited according to a specific operation that means storing the document. It has a function of storing in the document storage means 12.

The kanji → kana conversion dictionary 7 is a dictionary used by the kanji → kana conversion unit 6 to perform kanji → kana conversion.
The Japanese sentence conversion dictionary 9 is a dictionary used by the kana → Japanese sentence converting means 8 for converting kana → kanji kana interchange sentences.

In the present embodiment, the handwritten character recognition unit 3, the character recognition dictionary 4, the input character storage unit 5, the Kanji → Kana conversion unit 6, the Kanji → Kana conversion dictionary 7, the Kana → Japanese sentence conversion unit 8, the Kana → Japanese sentence conversion dictionary 9, The document editing means 10 is configured to be included in the arithmetic processing device 2.

Next, the operation of converting the kanji-kana conversion means 6 and the kana-Japanese sentence conversion means 8 into kanji-kana intersection sentences will be described with reference to FIG.

The conversion process is started when the conversion trigger is detected. At this time, first, the kanji-to-kana conversion means 6 takes out the characters stored in the input storage means 5 one by one,
If it is a kanji, it is converted to a kana and converted to a character string that does not contain kanji (210).

Here, FIG. 3 shows the configuration of the kanji-to-kana conversion dictionary 7 used for kanji-to-kana conversion. The kanji-to-kana conversion dictionary 7 comprises, in order of kanji code, a pointer part 31 having a pointer indicating the position where the corresponding reading is stored, and a reading part 32 storing the reading. When converting a kanji into a kana, a reading pointer corresponding to the kanji code is obtained from the pointer section 31 and replaced with the reading indicated by the pointer. If there is more than one reading for one kanji, replace it with the reading positioned at the beginning.

In this way, when a kanji is included, the kanji is converted into a kana, and the character string converted into a character string consisting of only kana is converted into a kanji kana alternate sentence by the kana-to-Japanese conversion means 8. (220). In the present embodiment, the conversion is performed on the level of consecutive clauses.

Next, check sequentially whether the kanji in the input string are included in the conversion result from the first character of the input string (230-3
30). That is, by these processes (230 to 330), as described below, the kanji kana interlaced Japanese text string output from the kana-to-Japanese text conversion means 8 is replaced with the Japanese text string input from the data input means. A processing means is configured to repeat the processing by the kanji → kana conversion means 6 and the processing by the kana → japanese text conversion means 8 until a kanji / kana interlaced Japanese character string containing the largest number of matched kanji is obtained by comparison. It will be. That is, first, the pointer is set to the head (23
0). Next, check whether the character is a kanji (240),
If it is a Kanji character, check whether the Kanji character exists at the corresponding position in the character string of the converted result (250). If so, consider that part as an appropriate conversion and move to the next character check. If the kanji does not exist, if there is a homonym in the phrase at the corresponding position, check whether or not the next homonym has the original kanji (260,270). If all the homonyms do not have the original kanji, the conversion is done again so that the bunsetsu delimiter of the corresponding bunsetsu is changed (280), and the new bunsetsu is checked for the original kanji. If the original kanji is not found even after checking all the bunsetsu divisions (290), the kanji is replaced with another reading for the input character string (300), and the above process is repeated. And
If you check all the readings (31
0), the clause of the part is left as the character of the input character string (320). In this way, all kanji in the input characters are repeated so that they are included in the converted character string (33
0).

Therefore, according to this embodiment, all the characters in the input character string are subjected to the above-mentioned processing, and the original kanji is left as it is and the most appropriate kanji kana alternation sentence is considered. Can be converted to.

In this embodiment, if the above-mentioned processing does not result in a kanji kana alternation sentence intended by the operator, a specific operation for the position coordinate detecting means 1 for further correcting the conversion result can be performed. However, the illustration is omitted.

According to the present embodiment, the operator can automatically convert the kanji kana kanji sentence of appropriate notation into a kanji kana kanji sentence of appropriate notation only by arbitrarily inputting the handwriting with the kanji kana kanji sentence which is easy to write. As a result, it is possible to realize a Japanese sentence input device by inputting handwritten characters with high input efficiency.

Further, in the present embodiment, when inputting with kanji crossing, as for the input kanji in the character string of the conversion result, it is possible to select the same phonetic object and re-separate the phrase until the kanji is left as it is. Since this is performed, the operator can partially eliminate the ambiguity that occurs in the kana-to-kanji kana interchange sentence conversion by appropriately including kanji when inputting by handwriting.

〔The invention's effect〕

According to the present invention, in a Japanese sentence input by handwriting character input, a character input in Kanji is converted into a kana once and then a kana → kanji kana interchange sentence conversion is performed, so the operator mixes kanji and kana, Since you can enter any data in the form that is the easiest for you to write, you can sufficiently improve the input efficiency.

Further, according to the present invention, for kanji input and included in kanji crossing, homonym opposition selection is repeated until the kanji is left as it is, which causes a problem in kana-kanji kana crossing conversion. It is possible to considerably suppress the occurrence of the Japanese syllabary, and it is possible to easily obtain correct sentence creation.
