Abstract

PURPOSE:To automatically register only the parts of independent words into a word dictionary by using a word register means which registers such words where the KANA (Japanese syllabary) character string and the KANJI (Chinese character) string extracted by an independent word extracting means show the reading and the description respectively in case the correction of these character strings is decided by a deciding means. CONSTITUTION:An independent word extracting means 8 extracts the parts of independent words out of the KANA character strings stored in a KANA character string memory means 3 and the KANJI-KANA character strings stored in a KANJI-KANA character string memory means 6. A deciding means 9 decides whether the KANJI-KANA character string produced by a KANA/ KANJI conversion means 5 is corrected or not. If so, a word register means 10 registers such words where the KANA character string and the KANJI- KANA character string extracted by the means 8 show the reading and the description respectively. In such a constitution, only the parts of independent words of the unregistered words can be automatically registered in case the character string inputted first is equal to an unregistered word and therefore unable to undergo the KANA/KANJI conversion.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a kana-kanji conversion device used in document processing devices such as Japanese word processors, and more specifically,
The present invention relates to a kana-kanji conversion device that effectively registers unregistered words in a dictionary during kana-kanji conversion.

(Prior Art) With the improvement of computer-based document processing technology, document processing devices such as Japanese word processors have come into general use. Users of document processing devices can efficiently create documents by using various functions. As an input function of this type of Japanese processing device, Kana-Kanji conversion is a method that inputs a desired character string containing kanji and kana using its pronunciation information, and then converts it into a character string containing kanji and kana using word dictionary searches and grammar test processing. This is widely contradictory because a character string containing many kanji and kana characters can be input in the form of kana or romaji using standard high-speed character input means such as a keyboard.

However, the drawback of kana-kanji conversion is that it cannot be converted unless the word is registered in the dictionary. Therefore, the user has to manually register the unregistered words, which is a heavy burden on the user.

To overcome this problem, we developed the Japanese Patent Application Laid-Open No. 63-257F36R Japanese Input Device as a conventional kana-kanji conversion device.
or has been proposed. This allows the user to input a kana character string, separate words, and select homonyms without being aware of whether the word is registered or not. The system identifies unregistered IT stories and registers them in the word dictionary. For example, "Keidanren"
Assume that the word is not registered. The user is
First, input ``Keidaren'' and try to convert it to kana-kanji. However, the conversion fails because "Keidanren" is not registered. Therefore, the user divides the input Gana character string into three parts, ``Kei'', ``Dan'', and ``Ren'', and then performs Kana-Kanji conversion. ``Keidanren'' is obtained by combining these words. At the same time, the above-mentioned "Japanese language processing device" is able to detect a word whose reading is the inputted character string "Keidanren" and whose notation is the finally obtained character string mixed with kanji and kana "Keidanren". , which can be registered in the word dictionary, so that from the next time onwards, the user can instantly get the word ``Keidanren'' for ``Keidanren.''

(Problems to be Solved by the Invention) As described above, in the conventional kana-kanji conversion device, the inputted kana character string is the reading, and the resulting kanji-kana mixed character string is the notation. Can be automatically registered in the dictionary. However, in the conventional method,
The entire input Kana string is treated as a word and registered as a word.

For example, the input string "Keitanrenkaikande1"
Assume that we obtain ``at Keidanren Kaikan'' obtained from .

In this case, first follow the steps explained above to get ``Keidanren'' for ``Keidanren'', then convert the remaining ``kaikande'' to ``kaikan de'' using normal kana-kanji conversion, and finally get ``kaikan de''. "at Keidanren Kaikan" can be obtained. At this time, an unregistered word whose reading is ``Keidanren Kaikande'' and whose notation is ``Keidanren Kaikan de'' is registered in the word dictionary. For this reason,
The next time ``Keidanren Kaikande'' is input, ``Keidanren Kaikan de'' will be obtained, but the 11 genitive parts will be different, such as ``Keidanrenkaikanni''. In this case, the previous results of word registration will not be utilized and it will be necessary to repeat the same procedure as ``Keidanren Kaikande'' again, which not only imposes a burden on the user but also reduces the efficiency of word registration. This was a significant loss.

(Means for Solving the Problems) The present invention overcomes the drawbacks found in the above-mentioned conventional devices, and
Provides a Kana-Kanji conversion device that can automatically register only the independent word part in a word dictionary out of the combination of the original Kana character string and the obtained Kanji-Kana mixed character string when an input Kana character string is modified. do.

According to the present invention, an input means for inputting a Kana character string to be subjected to Kana-Kanji conversion, a Kana character string storage means for temporarily storing the Kana character string, and a word having at least the pronunciation and notation of the word. a dictionary, a kana-kanji conversion means for generating a character string containing kanji and kana by referring to the word dictionary or selecting homophones based on the kana character string; and a correction means for modifying the character string containing kanji and kana; A kana-kanji conversion device comprising a kanji-kana-mixed character string storage means for temporarily storing a kanji-kana-mixed character string, and an output means for outputting the kanji-kana-mixed character string, wherein an independent word extracting means for extracting an independent word part from a kana character string and a character string containing kanji and kana in the kanji and kana character string storage means; and determining that the character string containing kanji and kana has been corrected by the correction means. A determination means,
and a word registration means for registering a word in which the character string extracted by the independent word extraction means is a pronunciation, the Kanji-kana mixed character string is the notation, and the character string extracted by the independent word extraction means is a spelling, if the determination means determines that the word has been corrected. It is possible to provide a Sugana-Kanji conversion device.

(Example) Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the figure, 1 is a control unit that controls the overall operation, and 2
3 is an input means for inputting a kana character string to be used for ephemeral kanji conversion, giving instructions necessary for generating a character string containing kanji and kana, such as selecting a homophone, specifying a break position, and modifying a kana character string; 3 is an input means; It is a kana character string storage means for temporarily storing the kana character string inputted by 2.
4 is a word dictionary that has at least the pronunciation and notation of words, 5 is a kana-kanji conversion means that generates a character string containing kanji and kana by referring to the word dictionary 4, grammatical analysis, homophone selection, etc.; Kanji-kana character string storage means 6 temporarily stores the kanji-kana mixed character string obtained by the kana-kanji conversion means 5; 7 is the kanji-kana character string storage means 6;
It is an output means for outputting the contents of 8 Hagana character string storage means 3, and an independent word part for extracting an independent word part from among the Kana character strings in the Hagana character string storage means 3 and the Kanji-Kana mixed character strings in the Kanji-Kana character string storage means 6. 9 is a determination means for determining whether or not a modification has been made when generating a character string containing kanji and kana by the Hagana-Kanji conversion means 5; 10 is determined to have been modified by the determination means 9; In this case, the independent word extraction means 8 is a word registration means for registering words in which the kana character string is the reading and the character string mixed with kanji and kana is the notation. Below, we will convert J to Gana-Kanji to get "Keidanren Kaikan", and at the same time, we will get "Keidanren Kaikan", which is the independent word part.
This embodiment will be described by taking as an example a case where a word is registered.

Note that FIG. 2 is a flowchart showing the flow of processing in the present invention. -i, 201 to 211 in the figure are identification numbers given for the convenience of the following explanation. Also, word dictionary 4
``kei'', ``dan'', ``ren'', and ``kaikan'', which correspond to ``kei'', ``tan'', ``ren'', and ``kaigan'', are registered, but ``Keidanren'', which corresponds to ``keidanren'', is not registered. It shall be assumed that this has not been done.

First, the user inputs the yorigana character string "Keidan Rengai Ikande" into the input means 2 (201).

The input kana character string is temporarily stored in the kana character string storage means 3 (202), and then passed to the kana-kanji conversion means 5 according to instructions from the control section 1. The kana-kanji conversion means 5 converts the kana character string into a character string containing kanji and kana by referring to the word dictionary 4 and performing a grammar test (203).

Here, since "Keidanren" is not registered in the word dictionary 4, the desired character string containing kanji and kana cannot be obtained (20
4). Therefore, the user performs a correction process from the input means 2 (20
5).

In this example, the kana character string “Keidanrengaikande” is −
Divided into ``KeiJ'', ``Dan'', ``Ren'', and ``Kaigande''. At this time, the control unit 1 informs the determining means 9 that the user has entered a character string containing kanji and kana from the input means 2 (206). The determination means 9 can be easily realized, for example, as a flag indicating whether or not it has been modified and a reading device thereof. Gana character string with specified delimiters ``Kei''``Dan'' ``
The words ``ren'' and ``kaigande'' are respectively converted into ``kei,''``dan,''``ren,'' and ``kaikan de'' by the kana-kanji conversion means 5 (203). Since the kanji-gana character string obtained by combining these is the desired one (204), when the user notifies the control unit 1 to that effect, the kana-kanji conversion process is completed and the kanji-kana character string "Keidanren "In the hall" is stored in the kanji-kana character string storage means 6 (207). It is assumed that the kana character string "Keidan Rengai Ikande" in the kana character string storage means 3 is stored without being changed during the above conversion/correction process.

The kanji-kana mixed character string in the kanji-kana character string storage means 6
"At Keidanren Kaikan" is read out by the control unit 1 to the output means 7 (208) and used for screen display, printing, editing processing in a word processor, etc. At this time, control section 1
In this case, the determining means 9 checks whether or not correction processing has been performed during the kana-kanji conversion (209), and in this example, since the determining means 9 indicates that the correction has been performed, Under the control of the control unit 1, the independent word extraction means 8 is activated.

The independent word extraction means 8 extracts the kana character string "Keidaren kaikande" from the kana character string storage means 3 and the kanji-kana mixed character string in the kanji-kana character string storage means 6 [in the independent word part from J at Keidanren Kaikan]. Some ``Keidanren Kaikan'' and ``
For example, a method of extracting an independent word such as "Keidanren Kaikan" (210) is a method for extracting an independent word, such as a word that is recognized as a non-independent word during the kana-kanji conversion process in the kana-kanji conversion means 5 (in this example, "de" in "kaikan de"). '' is recognized as a particle) to identify it as an independent word, and since independent words used as compound words are often composed of kanji, character strings containing kanji and kana are used. A method is applied that excludes the kana character string at the end (in this example, "de") and certifies the word as an independent word. After the independent word part is extracted, the control unit 1 gives an instruction to register the word to the registered vehicle Vj, 10. The registration means 10 registers the word extracted by the independent word extraction means 8 whose pronunciation is "Keidanrenkaikan" and the notation is "Keidanren Kaikan" (211). At this time, the compound word is Because it tends to be a noun, "Keidanren Kaikan"
It is also possible to register the part of speech in the word dictionary 4 as a noun. Additionally, the part of speech (noun) of the last word "kaikan" recognized by the Kana-Kanji conversion tool U can be given to "Keidanren Kaikan." Through the above steps, we will output "Keidanren Kaikan de" from the input Kana character string "Keidanren Kaikande", and also output "Keidanren Kaikan", which is an independent word part, in the word dictionary 4.
can be registered. Then, the next time you enter "Keidaren Kaikande", you will be able to enter "
"At Keidanren Kaikan" was obtained, and "Keidanren Gaikuni" was obtained.
You can also get ``Keidanren Kaikan ni'' by entering .

In addition, input means 2, kana character string storage means 3, word dictionary 4
, Kana-Kanji conversion means 5, Kanji-Kana character string storage means 6. The output means 7 is realized in a conventional Japanese word processor, etc., and the registration means 10 is
Except that the character strings used for registration are provided from the kana character string storage means 3 and the kanji kana character string storage means 6.
Since this has been realized in conventional Japanese word processors, detailed explanation will be omitted. Further, during kana-kanji conversion, operations such as homophone selection and confirmation of kanji conversion candidates are performed by instructions from the input means 2. There is also a procedure for converting and finalizing substrings of an input kana string in order from the beginning to generate a string containing kanji and kana. All of these processes are the same as those performed in conventional Japanese word processors, so their explanations will be omitted.

(Effects of the Invention) By using the present invention, the input Kana character string can be corrected and delimiters can be specified, etc., since the first Kana character string input by the user could not be converted into Kana-Kanji due to unregistered words. When the desired kanji/kana mixed character string is obtained by operation,
This is because only the independent word part of an unregistered word can be automatically registered S1.

From the next time onwards, you will be able to obtain the desired character string containing kanji and kana without any correction processing.
