Abstract

PURPOSE:To prevent an adverb, an auxiliary verb, a particle, and a conjunction which are normally expressed with HIRAGANA (a Japanese syllabary) from being expressed with KANJI (a Chinese character) by first searching a HIRAGANA dictionary when a KANA/KANJI conversion is carried out for Japanese sentences including clauses. CONSTITUTION:A dictionary selecting means 12 first selects a user dictionary. When a corresponding word exists in a concerned user dictionary and does not have a homophone to be aimed, a concerned dictionary searching means 14 sends it to a document editing device 6. When the aimed word cannot be found in the user dictionary, the dictionary selecting means 12 selects the dictionary according to the selection result of a successive conversion or a clause conversion. That is, when the successive conversion is selected, the HIRAGANA, dictionary is first selected, next, a general dictionary is selected. On the other hand, when the clause conversion is selected, the HIRAGANA dictionary is not selected, and the general dictionary is selected. Further, the aimed word is found in either dictionary, a HIRAGANA code or a KANJI code corresponding to it is outputted to the document editing device 6.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a kana-kanji conversion device, and more particularly to a kana-kanji conversion device that allows a term to be displayed in kana to be correctly displayed in kana the first time.

(Prior Art) Conventional workstations, word processors, etc. usually have functions such as sequential kana-kanji conversion and continuous clause kana-kanji conversion. This function is a function that converts a Japanese sentence of two or more clauses into a sentence containing Kanji and Kana. When using this function to convert kana to kanji, words that would normally be correctly written in hiragana, such as adverbs, auxiliary verbs, particles, and conjunctions, sometimes end up being converted to kanji. In addition, there is a problem in that words that are not registered in the kana-kanji conversion dictionary are assigned homophone kanji and are erroneously converted.

For example, there were problems in which the conjunction ``But,'' was incorrectly translated into ``Shikashi,'' and the adjective verb ``Konoshina'' was incorrectly converted into ``Chino-like.''

Therefore, conventionally, for adverbs, auxiliary verbs, particles, conjunctions, etc. that should be written in Hiragana, the corresponding Hiragana reading is registered in the header section of the Kana-Kanji conversion dictionary to prevent such misconversion. Was.

For example, as shown in Figure 5 for "ah", "like this", "but j", etc., the same hiragana as the heading is registered in the kanji heading section that corresponds to the heading section of the kana-kanji conversion dictionary. This prevents these words from being incorrectly converted into Kanji.

(Problem to be Solved by the Invention) However, if a device that converts Japanese sentences into Kanji-kana mixed sentences has a function of converting at least one phrase at a time, when input using this function, phrase conversion is required. In this case, the hiragana words in the dictionary are no longer needed. In other words, when a sentence is input using this function, for each phrase,
By pressing the kanji conversion key, etc., you can specify whether to input in hiragana or kanji, so the dictionary does not need to have words in hiragana, but only words that can be converted into kanji. It's a good thing.

As described above, in the conventional device, the same hiragana as the heading part is registered in the kanji heading part corresponding to the heading part of the kana-kanji conversion dictionary. Therefore, when inputting using the phrase-by-phrase conversion function, regardless of whether the phrase to be input is specified as a kanji, for example, a kana-kanji conversion dictionary that contains both kanji and hiragana must be searched. As a result,
There is a problem in that the amount of searches increases and the search time becomes longer.

The present invention eliminates the above-mentioned problems of the prior art, and when converting two or more Japanese phrases into a sentence containing kanji and kana, such as sequential kana-kanji conversion, continuous clause kana-kanji conversion, etc., adverbs, which are usually written in hiragana, For auxiliary verbs, particles, conjunctions, etc., hiragana is read out at once, while when converting one phrase at a time to a sentence containing kanji and kana, the search time is shortened.
An object of the present invention is to provide a kana-kanji conversion device with improved processing speed.

(Means and effects for solving the problems) The present invention has the following features:
In order to achieve the above-mentioned purpose, a hiragana dictionary and a bunsetsu dictionary are selected when a conversion method for converting a Japanese sentence containing multiple clauses into kana-kanji, such as successive conversion or continuous clause kana-kanji conversion, is selected. The present invention is characterized in that it is provided with at least a general dictionary that is selected when a conversion method for converting Japanese sentences that do not include multiple clauses into kana-kanji is selected, such as when converting a Japanese sentence that does not include multiple clauses, and is further provided with a means for selecting these dictionaries. There is.

According to the present invention, when a conversion method for converting a Japanese sentence containing multiple clauses into kana-kanji is selected, the hiragana dictionary is first selected and a search is performed using this dictionary, so that adverbs, auxiliary verbs, particles, conjunctions, etc. Words and phrases that are normally written in hiragana are displayed correctly in hiragana. On the other hand, when a conversion method is selected that converts a Japanese sentence that does not contain multiple clauses into kana-kanji, the general dictionary is directly searched without searching the hiragana dictionary, so the amount of words to be searched is small. , the search speed, that is, the kanji conversion speed becomes faster.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 2 shows a block diagram of one embodiment of the invention. In the figure, 1 is a word processor keyboard, 2 is a homophone display device, 3 is a character conversion device, 4 is a dictionary switching device,
5as 5bs 5C%... is a dictionary, and 6
indicates a document editing device.

Here, the character conversion device 3 searches for kanji in the dictionary using the kana characters input from the keyboard 1. If there are multiple kanji with the same nickname, the character conversion device 3 displays the kanji on the homophone display device 2, and when one of them is selected, the character conversion device 3 displays the kanji on the document editing device 6. It has a function to send to. Furthermore, the dictionary switching device 4 has a function of selecting one or more specified dictionaries from among a plurality of dictionaries.

Dictionary 5 as 5 b'= 5 C%... is,
A Hiragana dictionary that collects only clauses that are usually written in Hiragana, such as adverbs, auxiliary verbs, particles, conjunctions, etc. 5as A Kana-Kanji conversion dictionary (hereinafter referred to as the general dictionary) that consists only of Kanji that do not include Hiragana. ) 5b1 user dictionary 50, etc. FIG. 3 shows a conceptual diagram of the hiragana dictionary 5a.

As is clear from the figure, terms that are usually written in kana are registered in the "heading section", and words that are the same as the terms in the heading section are registered in kana in the "kanji heading".

Note that each dictionary may have identification information as to whether the dictionary is a hiragana dictionary, a general dictionary, or a user dictionary, or it may be stored in a separate file for each dictionary group. It may also be included as information that describes the configuration of.

Next, the operation of this embodiment will be explained with reference to FIG.

FIG. 4 is a flowchart showing the functions of the character conversion device 3 shown in FIG. 2.

First, the operator displays on the screen an initial menu for selecting the kana-kanji conversion mode to be used when creating a document. The following display is displayed on the screen.

Conversion method (1) Sequential conversion (or continuous clause kana-kanji conversion) (2) The clause conversion operator selects one of the above-mentioned kana-kanji conversion modes, and then converts the word or phrase using the keys on keyboard 1.
When input in kana or romaji, this word is converted into a character code and stored in a storage device within the character conversion device 3. When the character code of the phrase is stored in the storage device, next, the character conversion device 3 accesses the address of the storage device where the code of the phrase is stored (step Sl
).

Next, the user dictionary 5c is searched for the character code stored at the address (step S2). If it is not registered in the user dictionary, the process advances to step S4;
Determine whether successive conversion (or continuous clause kana-kanji conversion) is selected.

If yes, the hiragana dictionary is searched using the character code (step S5). As a result of searching the hiragana dictionary, if the word is registered (YES in step S6), the hiragana of the word is sent to the document editing device 6 (step 89).

On the other hand, when the step S4 or S6 is NO, "
A search is performed on a general dictionary in which only kanji are registered in the ``kanji heading'' (step S7). Next, it is determined whether there is a homophone or not (step S8), and if there is no homophone (no in step S8), the kanji of the word is sent to the document editing device 6 (step S9).

When the answer in step S3 is YES, the process proceeds to step SIO, where it is determined whether there are homophones. If there is no homophone, the process proceeds to step S9, and the word/phrase converted into kana-kanji is output to the document editing device 6. Conversely, when the step SIO is YES, a homophone buffer is created (step 511) and displayed on the homophone display device 2. Also, when step S8 is YES, a homophone buffer is created (step 512).
, is displayed on the homophone display device 2. Thereafter, homophone processing is performed (step 513), and the selected words are output to the document editing device 6.

Finally, a judgment is made as to whether the character input operation has been completed (step 514), and if the answer is 1, the process returns to step S1 and the same pf)J,..., steps as above are repeated. It will be done. When step S14 is finally completed, the series of operations described above ends. 5. , , , - , , and the selected kanji are homophone-processed in step S13 and are registered in the user's dictionary.

As a result, when the same word is input again, the previously selected kanji will be selected preferentially, and a learning effect can be expected.

In this embodiment, since the hiragana dictionary 5a has the configuration shown in FIG. 3, it can be implemented without any changes to the conventional specifications. Note that the hiragana dictionary 5a may have another form. In other words, the "kanji heading" in Figure 3 is the "heading section"
Since the contents are the same, the "Kanji heading" is deleted, and if it is determined in step s6 that it is registered, a "yes" flag is set, and if it is not registered, the flag is not set. Good too.

Next, this embodiment will be explained using an actual example.

Now, when the operator selects successive conversion on the initial menu and then inputs "What do you mean?" from the keyboard 1, the character conversion device 3 inputs "What do you mean?" in step S5.
The hiragana dictionary 5a is searched word by word from the beginning of the sentence, such as "do", "do", "doi", "doi", "douitsu", etc. If the hiragana dictionary 5a has a header section as shown in FIG. 3, the word ``Doui'' is the longest headword, so ``Doui'' is determined first. Next, the rest of the words, ``motonde'', start from the beginning of the sentence with ``tsu'', ``tmo'', ``tchiri'',
``Kokumo de'' is searched, and since ``Kokumo de'' is the longest headword, ``Koku de'' is determined. lastly,
"De" is determined, and the character information "What do you mean" in hiragana is sent from the character conversion device 3 to the document editing device 6, where it is displayed on the display.

FIG. 1 shows a schematic functional block diagram of the character conversion device 3 shown in FIG. 2. As shown in FIG.

11 is a means for holding the selection result of successive conversion (or Renbun-bushikana-kanji conversion) or bunsetsu conversion by the initial menu;
12 is a dictionary selection means. Further, 13 is a means for storing the code of the input character, 14 is a dictionary search means for reading out the character code and searching the dictionary selected by the dictionary selection means 12, and 15 is a homophone processing means.

The dictionary selection means 12 first selects a user dictionary. The dictionary search means 14 sends the word to the document editing device 6 if the word or phrase is found in the user's dictionary and there is no homophone. On the other hand, if there is a homophone, the homophone is processed by the homophone processing means 15 and then sent to the document editing device 6.

When the target word/phrase cannot be found in the user dictionary, the dictionary selection means 12 selects a dictionary according to the selection result of successive conversion or clause conversion.

That is, if successive conversion is selected, the hiragana dictionary is selected first, and then the general dictionary is selected.

On the other hand, if bunsetsu conversion is selected, the general dictionary is selected without selecting the hiragana dictionary.

When a target word is found in one of the dictionary widths, the corresponding hiragana or kanji code is output to the document editing device 6, and the dictionary search for the next word is started. Note that when a homophone is output as a result of the dictionary search, the homophone is processed by the homophone processing means 15 and output to the document editing device 6.

(Effects of the Invention) As is clear from the above description, according to the present invention, when a conversion method for converting a Japanese sentence containing a plurality of clauses into kana-kanji, such as successive conversion or continuous clause kana-kanji conversion, is selected, First, the Hiragana dictionary is searched, so clauses that are normally written in Hiragana, such as adverbs, auxiliary verbs, particles, conjunctions, etc., are not written in Kanji on the display. Furthermore, since the search is first performed using the Hiragana dictionary, there is also the effect that the search speed is fast.

On the other hand, when a conversion method is selected, such as bunsetsu conversion, in which a Japanese sentence that does not contain multiple clauses is converted into kana-kanji, the search in the hiragana dictionary is omitted, and the general dictionary in which only kanji are directly registered is selected. Since the search will be performed, there is an effect that the search speed becomes faster.
