Abstract

PURPOSE:To eliminate the need for a troublesome job for registering words in a word dictionary by registering automatically KANJI (Chinese characters) strings in the word dictionary in response to input KANA (Japanese syllabary) strings subjected to KANJI conversion after punctuation. CONSTITUTION:A KANA/KANJI converting part 5 converts the input KANA character strings inputted from a keyboard 1 into the KANJI-KANA character strings by referring to a word dictionary 6. An unregistered word discriminating part 7 carries out KANA/KANJI conversion through the part 5. If a KANJI- KANA character string corresponding to an input KANA character string is not registered yet in the dictionary 6, the input KANA character string is divided into plural KANA character strings and then individually converted into KANJI by the part 5. Then it is discriminated that these KANJI are converted into unregistered words. The unregistered words discriminated by the part 7 are registered in the dictionary 6 via a word register part 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a Japanese input device, and more particularly to a Japanese input device that converts a kana character string into a kanji-kana mixed character string and inputs the converted character string.

[Conventional technology]

Conventionally, as this type of Japanese input device, a device is known that converts an input kana character string into a kanji-kana mixed character string by referring to a word dictionary.

In such Japanese input devices, not all existing kanji words are registered due to the limited capacity of the word dictionary, and the input kana character string may not be converted to a kanji kana mixed character string. is born.

In such cases, conventional Japanese input gW re-separates the input kana character string and sequentially repeats kana-kanji conversion on the re-separated parts of the kana character string to create the desired kanji-kana mixed character string. is input.

Additionally, conventional Japanese input devices are generally equipped with a means for newly registering kanji base words that are not registered in the word dictionary; Once registered in the word dictionary, there is no need to separate the kana character strings when inputting the same kanji word. However, in this case, it is necessary to roughly register the kanji words to be used in a word dictionary.

[Problem that the invention seeks to solve]

The above-mentioned conventional Japanese input device has a drawback in that when inputting an unregistered kanji preword, the input kana character string must be re-separated and inputted.

Furthermore, even with a Japanese input device having a word registration function, the word must be registered in a word dictionary, and this word registration work is complicated.

In view of the above-mentioned points, an object of the present invention is to convert the input Kana character string into Kana-Kanji when the input Kana character string is re-separated and converted into Kana-Kanji. To provide a Japanese input device which automatically registers a Kanji/Kana character string corresponding to an input Kana character string in a word dictionary after negative completion.

[Means for solving problems]

The Japanese input device of the present invention includes an input means for inputting an input kana character string to be subjected to kana-kanji conversion, a word dictionary means for accumulating kanji word information for the input kana character string, and an input means input by the input means. A kana-kanji conversion means converts a kana character string into a kanji-kana mixed character string with reference to the word dictionary means, and the kana-kanji conversion means performs kana-kanji conversion to convert the input kana character string into a kanji-kana mixed character string. An unregistered word that determines that, when the input kana character string is not registered in the dictionary means, the input kana character string is divided into a plurality of kana character strings and individually converted into kana-kanji by the kana-kanji conversion means and converted into the unregistered word. It has a word discriminating means, and a word registering means for registering the unregistered word discriminated by the unregistered word discriminating means in the word dictionary means.

[Effect]

In the Japanese input device of the present invention, the input means inputs an input kana character string to be subjected to kana-kanji conversion, the word dictionary means stores kanji word information for the input kana character string, and the kana-kanji conversion means inputs the input kana character string by the input means. The input kana character string is converted into a kanji-kana mixed character string by referring to the word dictionary means, and the unregistered word discrimination means performs kana-kanji conversion by the kana-kanji conversion means to convert the input kana character string into a kanji-kana mixed character string. is not registered in the Kana dictionary means, it is determined that this input Kana character string is divided into a plurality of Kana character strings and individually converted into Kana-Kanji by the Kana-Kanji conversion means, and converted into an unregistered word; The word registration means registers the unregistered word determined by the unregistered word determination means into the word dictionary means.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a Japanese language input device according to an embodiment of the present invention. This Japanese input device consists of a keyboard for inputting kana character strings, input kana character strings (hereinafter simply referred to as input kana character strings), and converted character strings containing kanji and kana characters (hereinafter referred to as input kana character strings). a display device 2 that displays kanji character strings), a human output control unit 3 that controls input from the keyboard 1 and output to the display device 2, a Japanese text management unit 4 that manages Japanese text as Japanese text; a kana-kanji conversion unit 5 that converts input kana character strings entered from the keyboard 1 into kanji character strings by referring to a word dictionary 6; and a kana character string and kana characters. A word dictionary 6 stores kanji words corresponding to columns, and when a kanji character string corresponding to an input kana character string is an unregistered word that is not registered in the word dictionary 6, this unregistered word is re-separated. An unregistered word discriminating section 7 distinguishes 91 whether the unregistered word has been converted by the Tekana-Kanji converting section 5, and a word registration section 8 registers the unregistered word discriminated by the unregistered word discriminating section 7 in the word dictionary 6. The main parts are configured.

Referring to FIG. 2, the registration process for unregistered words in the Japanese input device of this embodiment includes a remaining kana character string initialization step 21, a word dictionary search step 22, a conversion possible/impossible determination step 23, a step 24 for displaying that conversion is not possible and waiting for user instructions; a step 25 for determining whether to re-delimit input kana character strings; a step 26 for re-separating input kana character strings; a step 27 for displaying conversion results and waiting for user instructions;
Homophone selection determination step 28, Homophone selection step 29, Conversion result storage step 30, Remaining Kana character string presence determination step 31, Input Kana character string resetting step 32, Re-segmentation determination step 33 and,
It consists of a conversion result and kana character string notification step 34 and a conversion result output step 35.

Next, the operation of the Japanese language input device of this embodiment configured as described above will be explained. Note that here, a case where the kanji character string corresponding to the input kana character string is an unregistered word will be explained in detail.

When the user inputs a kana character string from the keyboard 1 and requests kana-kanji conversion, the input/output control section 3 displays the input kana character string on the display device 2 and sends it to the kana-kanji conversion section 5.

The kana-kanji conversion unit 5 initializes the input kana character string supplied from the input/output control unit 3 with no remaining kana character strings (step 21), and searches the word dictionary 6 for the input kana character string (step 22). .

If a kanji character string corresponding to the input kana character string is registered in the word dictionary 6, a kanji character string can be obtained, but in this case, since the input kana character string is an unregistered word, the corresponding kanji character string Therefore, when determining whether the kana-kanji conversion was possible or not (step 23
), it becomes impossible.

Therefore, the kana-kanji conversion section 5 displays on the display device 2 via the input/output control section 3 that the conversion was not possible, and waits for an instruction from the user (step 24).

The user sees the display on the display device 2 indicating that the kana character string has not been converted to a kanji character string, and selects whether to re-separate the input kana character string and input the kana characters as they are for kana-kanji conversion. and give instructions. In this case, it is assumed that an instruction to re-divide has been given.

When an instruction to re-divide the input kana character string is given, the unregistered word discriminator 7 determines this instruction (step 25).
, the delimited part is input as an input kana character string, the part left after the delimitation is memorized as the remaining kana character string, and it is necessary to remember to re-delimit it.
I is returned to step 22.

In step 22, the word dictionary 6 is searched again using the re-divided input kana character string, and it is again determined whether the conversion is possible or not (step 23).

Here, if the conversion is successful, the kana-kanji converter 5 displays the conversion result on the display device 2 via the input/output controller 3 and waits for the user's instructions (
Step 27).

The user recognizes the kanji character string displayed on the display device 2 and, if the conversion result matches the desired kanji character string, instructs the user to leave the displayed kanji character string as is. If the displayed Kanji character string is a homophone different from the desired Kanji character string, a reconversion request is issued from the keyboard 1.

When an instruction from the user is input, it is determined whether the instruction is a reconversion request for selecting a homophone (step 28). If the instruction is to select a homophone, the kana-kanji converter 5 searches the word dictionary 6 for the next candidate kanji character string, displays it on the display device 2, and selects a homophone according to the user's instruction. is performed (step 29). If the selection is not a homophone, no homophone is selected, and then the obtained conversion result is stored (step 30).

Next, the unregistered word discriminator 7 determines whether there are remaining kana character strings (step 31), and if there are remaining kana character strings, the remaining kana character strings are used as input kana character strings (step 32).
, return to step 22. In this case, there are remaining kana character strings, so control returns to step 22.

By repeating the above-described kana-kanji conversion process by re-dividing the input kana character string, the user can create a desired kanji character string for the input kana character string.

When it is determined in step 31 that there are no remaining kana character strings for the input kana character string, the unregistered word determining section 7 determines whether there has been a re-break or not (step 33). In this case, since there has been a re-delimitation, the unregistered word discriminator 7 notifies the word registration unit 8 of the converted kanji character string and the input kana character string, which are a combination of all the re-delimited parts (step 34). ). The word registration unit 8 registers the notified kanji character string as the conversion result and the input kana character string in the word dictionary 6.

Thereafter, the conversion result is output from the kana-kanji conversion unit 5 to the Japanese text management unit 4 and stored therein (step 35).

The next time you enter the same input Kana character string and perform Kana-Kanji conversion, the corresponding Kanji character string is already registered in the word dictionary 6, so this Kanji character string can be searched in one operation. Tekana Kanji conversion is performed.

In this way, in the Japanese input device of this embodiment, the kanji character string can be registered in the word dictionary 6 without any special operation.
The kanji character string is automatically registered in the word dictionary 36 when the input kana character string is re-divided and converted into kana-kanji.

Note that if kana-kanji conversion has not become disabled, or if the input kana character string has not been re-separated even if kana-kanji conversion has become disabled, the execution of step 34 will be skipped based on the determination in step 33. Needless to say, the word is not registered in the word dictionary 6.

〔Effect of the invention〕

As explained above, the present invention automatically registers in a word dictionary a kanji character string corresponding to an input kana character string that cannot be converted by a single kana-kanji conversion but is re-divided and converted into kana-kanji. This has the effect of converting the same input kana character string into a desired kanji character string with a single kana-kanji conversion operation from the next time without performing the complicated operation of registering unregistered words in advance.
