Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an old kana-kanji conversion device and method in a document creation device for converting a hiragana character string into a kanji-kana mixed sentence.

[0002]

2. Description of the Related Art Generally, in a document creating device, kana-kanji conversion is performed on an input hiragana character string,
A kanji-kana mixed sentence is created. In the kana-kanji conversion, a kana-kanji conversion result is obtained by referring to a dictionary in which words and phrases are registered and determining the delimiters in input character strings and the connection relations of words and phrases.

The document creation device has a document that is normally created,
That is, a function for creating a modern sentence and a dictionary are provided. Therefore, for example, even if a character string used in an old sentence such as "Tanoshi-Keri" is input and Kana-Kanji conversion is performed, it is often not correctly converted to "Kashi-Kiri".

To solve such a problem, it is conceivable to convert an old text character string by having a dictionary dedicated to old text. However, since the dictionary for Kana-Kanji conversion has a large amount of information, this dictionary requires a large amount of memory and a storage medium such as a magnetic disk device in the document creation device.

[0005]

As described above, in the conventional document creating apparatus, regarding the character string relating to the old text,
The Kana-Kanji conversion could not correctly convert to a Kanji-Kana mixed sentence. Further, if a dictionary dedicated to old texts is prepared, there is a problem that many storage media such as memories and magnetic disk devices are required.

The present invention has been made in view of the above points, and an object of the present invention is to provide an apparatus and method for converting Kana-Kanji into Kanji and Kanji that can perform Kana-Kanji conversion on an old sentence without having a dictionary dedicated to the old sentence. And

[0007]

According to the present invention, in a document creating apparatus for converting a hiragana character string into a kanji / kana mixed sentence, a stem extracting means for extracting a stem portion from input hiragana character string information, and the stem extraction. Modern word information is generated based on the stem portion extracted by the means, and the modern word conversion means for obtaining the kana-kanji conversion result for this modern word information and the ending of the kana-kanji conversion result obtained by the modern word conversion means , And a reducing means for reducing the input hiragana character string information to the word tail portion.

[0008]

According to such a configuration, by converting the input Hiragana character string information once into a modern word, it is possible to perform Kana-Kanji conversion using a dictionary for normal Kana-Kanji conversion processing. You don't need a dictionary.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a document creation apparatus having an old-kana-kanji conversion function according to the embodiment. As shown in FIG. 1, the document creation apparatus includes a keyboard 1
0, input control unit 12, display 14, display control unit 1
6 and a kana-kanji conversion unit 18.

The keyboard 10 receives the key operation by the user, and inputs the input information necessary for creating a text or the like to the input control unit 1.
It is for inputting via 2.

On the keyboard 10, in addition to the up / down / left / right cursor keys for moving the cursor to specify various character keys, various function items, and the range of document editing, the present invention relates to modern sentences. The [Convert / Next candidate] key for instructing to convert a Hiragana character string into a Kanji / Kana mixed sentence and for executing the next candidate process, and for converting an Hiragana character string related to an old sentence into a Kanji / Kana mixed sentence [Convert] key, [Select / Execute] key for instructing confirmation of various settings, [Correction] key for instructing correction of various setting contents, for instructing interruption of processing or cancellation of input before confirmation Various function keys including a [Cancel] key, a [Delete] key used for creating, editing, and proofreading a document, an [Insert] key, and the like are provided.

When the [conversion / next candidate] key is pressed after the hiragana character string is input, the keyboard 10 outputs conversion mode data indicating that the conversion mode is "modern sentence conversion mode", and When the] key is pressed, the conversion mode data indicating that the conversion mode is the "old text conversion mode" is output.

The input control section 12 is for inputting an effective key input from the keyboard 10. The input control unit 12 is also provided with a conversion mode check unit 12a. The conversion mode check unit 12a activates a normal kana-kanji conversion process or an old kana-kanji conversion process based on the conversion mode data instructed from the keyboard 10.

The display 14 is composed of, for example, a liquid crystal display, and the display control section 16 controls the display. The display control unit 16 causes the display 14 to display a hiragana character string input from the keyboard 10, a kana-kana mixed sentence converted by the kana-kanji conversion unit 18, and the like.

The kana-kanji conversion section 18 includes a kana-kanji conversion processing section 18a, a dictionary 18b, and an old-text kana-kanji conversion processing section 18.
c is provided. The kana-kanji conversion processing unit 18a performs normal kana-kanji conversion processing (that is, a modern sentence) with reference to the information stored in the dictionary 18b. Dictionary 18b
Stores information for performing a normal Kana-Kanji conversion process, and does not store information about old texts.

The ancient sentence kana-kanji conversion processing unit 18c is for performing a kana-kanji conversion process for a character string related to an old sentence in the ancient sentence conversion mode. The stem extraction processing unit 18c1, the modern language conversion processing unit 18c2, and the ending reduction processing unit 18c3. It is provided.

The word-stem extraction processing unit 18c1 checks the input hiragana character string for the existence of a word ending peculiar to an old sentence, and if there is, deletes the word ending and extracts the word stem. The modern word conversion processing unit 18c2 is the stem extraction processing unit 18
A modern language is generated based on the stem extracted in c1. At this time, the modern language conversion processing unit 18c2 generates a modern language based on the rule registered in “old sentence → modern sentence (grammar) conversion data” (not shown). Furthermore, the modern language conversion processing unit 18c2 causes the Kana-Kanji conversion processing unit 18a to execute the generated modern Kana-Kanji conversion processing.
The ending reduction processing unit 18c3 performs processing for returning the character string obtained as a result of the kana-kanji conversion to the ending of the input hiragana character string.

Next, the operation of kana-kanji conversion in the embodiment will be described with reference to the flow chart shown in FIG. First, when a character key on the keyboard 10 is pressed, the input control unit 12 receives a key input and inputs a hiragana character string. The input character string is displayed on the display 14 under the control of the display control unit 16.

When the "modern sentence conversion mode" key is pressed here, the conversion mode check unit 12a checks the conversion mode data (step S1).

When the conversion mode is the "modern sentence conversion mode" (step S2), the input control section 12 activates the normal kana-kanji conversion processing in the kana-kanji conversion section 18.
In this case, the kana-kanji conversion processing unit 18a performs normal kana-kanji conversion for the input hiragana character string with reference to the dictionary 18b (step S3).

On the other hand, after the hiragana character string is input,
When the [Old sentence conversion] key is pressed, the conversion mode check unit 12a determines that it is in the "Old sentence conversion mode" (step S2), and activates the old sentence Kana-Kanji conversion processing unit 18c of the Kana-Kanji conversion unit 18.

Here, a case in which the hiragana character string “Tanoshikeri” relating to an old sentence is input will be described as an example. First, the word stem extraction processing unit 18c1 checks the presence / absence of a word ending peculiar to an old sentence by referring to a table in which the word endings in an old sentence are registered, as shown in FIG. 3, for example.

When the input character string has an ending that is peculiar to an old sentence, the stem extraction processing unit 18c1 deletes the corresponding ending and extracts the stem (step S4). In the case of the character string "Enjoy", as shown in Fig. 4 (a), "Enjoy"
Is obtained as a word stem.

Next, the modern word conversion processing unit 18c2 generates a modern word from the word stem extracted by the word stem extraction processing unit 18c1 based on "old sentence → modern sentence (grammar) conversion data" (step S5). .. A rule such as "Add a word" i "to the stem of a word ending in" idan "" is registered in the "old sentence to modern sentence (grammar) conversion data".

In accordance with this rule, the modern word conversion processing section 18c2 adds "i" to the character string "enjoy" of the stem to generate a modern word "enjoy", as shown in FIG. 4 (b). To do.

The format and type of the rule registered in "old sentence → modern sentence (grammar) conversion data" are not particularly limited. Further, a plurality of rules may be applied to one character string, and in this case, the priority order applied to the rules is set in advance.

The modern-language conversion processing section 18c2 carries out step S
The kana-kanji conversion processing unit 18a is requested to perform kana-kanji conversion for the modern language generated in step 5. Kana-Kanji conversion processing unit 1
8a searches the dictionary 18b for the generated modern language (Hiragana character string) (step S6). As a result, when the corresponding character string is not in the dictionary 18b,
The modern-language conversion processing unit 18c2 displays “old text → modern text (grammar)”
The modern word is again generated according to the rule of the next candidate in the "converted data", and the dictionary 18b is searched (step S).
5, S6).

Assuming that the generated character string corresponding to the modern word "Tanoshi" is registered in the dictionary 18b (step S7), the kana-kanji conversion processing unit 18a performs the same kana-kanji conversion as shown in FIG. As shown in c), the kana-kanji conversion result of "fun" is obtained (step S).
8).

The ending reduction processing section 18c3 restores the result of the kana-kanji conversion to the original old-word ending based on the characters deleted or added to the character string in steps S4 and S5 (step S9).

As for the character string "happy" obtained as a result of kana-kanji conversion, as shown in FIG.
The character "i" added in 5 is deleted, and the character "keri" deleted in step S4 is added. As a result, the kana-kanji conversion result "funshikeri" corresponding to the hiragana character string "tanoshishieri" related to ancient text is obtained.

Further, the document creation apparatus provided with the old-language kana-kanji conversion processing section 18c can edit the following documents. After creating a document in which old and modern sentences are mixed, the conversion of the created document to old or modern sentence is instructed.

For example, when conversion to a modern sentence is instructed, the stem extraction processing unit 18c1 obtains a word of an old sentence while checking whether or not each word in the created document has an ending peculiar to an old sentence, Find the stem of each word. The modern word conversion processing unit 18c2 adds the ending of the modern word to the stem according to the rule in “old text → modern text (grammar) conversion data” and converts the word into a modern text.

When conversion into an old sentence is instructed, the modern sentence conversion processing unit 18c2 and the stem extraction processing unit 18c1 convert the modern sentence into the old sentence by a procedure reverse to the process of converting the old sentence into the modern language. ..

In this way, when the Hiragana character string is converted into Kana-Kanji, the correct Kana-Kanji conversion result corresponding to the Hiragana character string relating to the old sentence can be obtained by designating the "Old sentence conversion mode". At this time, the Kana-Kanji conversion result is obtained by generating modern Kana-Kanji conversion based on the input character string and returning the conversion result to the end of the old sentence. Don't need Therefore, many storage media such as memories and magnetic disk devices are not required.

[0035]

As described above, according to the present invention, it is possible to perform kana-kanji conversion for old texts without having a dictionary dedicated to old texts.
