Abstract

PURPOSE:To reduce the possibility of misconversion by outputting the KANJI (Chinese character) candidates of higher preference ranks in terms of the connecting relation with the character string set right before the inserting position of the KANA (Japanese syllabary) data. CONSTITUTION:When a KANA/KANJI conversion key of an input means is pushed after the end of input of KANA, an editing control part 3 sends an instruction to a KANA/KANJI conversion control part 7. Thus the KANA/ KANJI conversion is applied to the KANA character strings stored in an input KANA train storage part 2. The part 7 performs this conversion operation by reference to the grammar information stored in a pre-contact grammar information storage part 6, an inter-part-of-speech table 4, and a word dictionary 5. At the same time, a word which is corrected by the several head characters of the input KANA train is retrieved out of the dictionary 5. Thus the first word candidate is obtained. Then it is decided whether each candidate can be connected to a pre-contact word or not by reference to the table 4 and the part 6. Then the KANA/KANJI conversion operations are successively carried out. As a result, the candidates of KANJI-KANA mixture sentences are obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a kana-kanji conversion device that converts characters input in the form of kana into strings containing kana and kanji.

2. Description of the Related Art In recent years, kana-kanji conversion devices have been widely used in various Japanese language processing devices, including Japanese word processors, as devices for inputting Japanese characters.

A conventional kana-kanji conversion device has a function of converting an input kana string into a kana-kanji mixed string.

For example, the following kana column I'm going to the cafe.

If you enter I'm going to work.

You can perform the conversion with In addition, Japanese word processors use the editing function for documents input using a kana-kanji converter, and then use the kana-kanji converter to make additions and corrections, creating a document similar to a more sophisticated one. You can create and edit other documents efficiently. For example, in the example shown above, by moving the character cursor to the position of ``kai'' and inputting ``kuruma'' to perform kana-kanji conversion, I drive to work.

You can make additions and corrections.

Problems to be Solved by the Invention However, conventional kana-kanji conversion devices use an input method based on phrase units, and in particular, it is difficult to obtain appropriate conversion results unless the beginning of the input string is an independent word. I can't. For example, assume that a sentence like the one shown in the previous example has already been input.

I go to work by car.

Suppose you want to further modify this sentence and change it to ``The manager and I are going to the office.'' As an example of the editing operation performed by the user at this time, assume that the user places the character cursor on "ba" and inputs "tokacho" to perform kana-kanji conversion. However, since conventional kana-kanji conversion is based on inputting phrases,
Regardless of what is input at the cursor position, the Kana-Kanji conversion device will
For example, a conversion result of "wading bird" is output. Therefore,
The overall sentence is: I, a wading bird, go to work by car.

This results in conversion results that are not intended by the user.

Means for Solving the Problem In order to solve this problem, the present invention uses a connection table that stores the priority of the connection relationship between a certain character string and another character string, and inserts characters in 9 sentences including kana and kanji. It is composed of a means for outputting a character board with a high priority in connection relationship with a plurality of kanji candidates corresponding to the kana data inputted as a character string to be inserted and the dial board immediately before the position specified to be inserted.

Effect: In this configuration, when converting kana data to be inserted into kanji, a kanji candidate with a high priority is output in terms of the connection relationship with the character string immediately before the insertion position of the kana data.

Embodiment Hereinafter, a kana-kanji conversion device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a functional block diagram of a kana-kanji conversion device according to an embodiment of the present invention, in which 1 is an input means for inputting and editing a kana string, and 2 is an input means for inputting a kana string input from the input means 1. 3 is an editing control unit that controls document editing work; 4 is a part-of-speech connection tape that records whether or not words with each part-of-speech attribute can be grammatically connected;
6 is a word dictionary that stores word pronunciations, kanji notations, and part-of-speech information in pairs; 6 is a prefix grammar information storage unit that stores designated grammatical information; 7 is a part-of-speech connection Tef/I/4 and a kana-kanji conversion control unit which examines the word dictionary 5 while referring to the grammatical information stored in the prefix grammar information storage unit 6 and converts the kana string stored in the input kana string storage unit 2 into a kanji-kana mixed string. , 8 is a document buffer that stores the result of conversion by the kana-kanji conversion control unit 7, 9 is an output character string storage unit that stores the kanji-kana mixed string output from the kana-kanji conversion control unit, and 10 is a document buffer that stores the result of conversion by the kana-kanji conversion control unit 7. This is a display means for displaying nine strings of mixed kanji and kana characters stored in the output character string storage section.

FIG. 2 is a circuit block diagram of the kana-kanji conversion device of this embodiment, in which 11 is a keyboard, the keyboard 11 includes kana-kanji conversion keys 11a1 for performing kana-kanji conversion, 1a character cursor for indicating the edit operation position in the text. It is equipped with a character cursor movement key 11b for moving the character cursor, a character input key 11c for inputting kana characters, etc., and 12 is a central processing unit (
Hereinafter, it will be abbreviated as CPU. ), 13 is a cathode ray tube display (hereinafter abbreviated as CRT display), 14
is read-only memory (hereinafter abbreviated as ROM).
, 16 is a random access memory (hereinafter abbreviated as RAM).

The human power means 1 shown in FIG. The prefix grammar information storage unit 6, the output character string storage unit 99, the document buffer 18 are stored in the RAM 16, and the part-of-speech connection tape)'v 4 *The word dictionary 5 is stored in the ROM 14, edited by the editing control unit 3. Kana-kanji conversion device part is CPU12
The display means 1o is realized by the CRT display 13 by executing a program stored in the ROM 14 while exchanging data with the ROM 14 and the RAM 16.

The operation of the kana-kanji conversion apparatus of this embodiment configured as described above will be explained below based on the flowchart shown in FIG.

While editing the text displayed as shown in Figure 4,
Document buffer 8 contains data as shown in FIG. That is, the document data is stored for each word with its grammatical information as bare information, and also has a break for each clause.

First, in step A, the user presses the character movement key 11.
If you use b to match the character curfew at the position of “ha”,
The editing control section 3 recognizes that the input data is a character cursor movement key in step B, and moves the cursor on the screen in step C. Furthermore, in step D, it is determined that the grammatical information preceding the current Kanle position is a "personal pronoun", and this is stored in the grammatical information storage section θ, as shown in FIG. 6, and the process returns to step A. .

Further, in step A, when the user inputs one kana character, for example, "to" using the character input key 11c, the editing control unit 3 recognizes that the input data is a kana character in step E, and in step F The input kana characters are additionally registered with "to" in the input kana string storage section 2. In this case, since it is the beginning of the input, only "to" is stored in the input kana string storage section 2. Also, the editing control section 2 simultaneously stores the contents of the input string storage section 2 in the output string storage section 9, and displays it on the display means 1o.

By repeating steps A, E, and F above, the input kana notation data "Togachou" is stored in the input kana string storage section 2.

After completing the input of kana, when the user presses the kana-kanji conversion key 11a in step A, the editing control unit 2 proceeds to step G.
It is recognized that the kana-kanji conversion key 11a has been pressed, and in step H the input kana string storage unit 2 is input to the kana-kanji conversion control unit 7.
Instructs to perform kana-kanji conversion on the kana character string stored in . The kana-kanji conversion control unit refers to the grammar information 1 part-of-speech connection table 4 stored in the prefix grammar information storage unit 6 and the word dictionary 6, and performs kana-kanji conversion.

FIG. 7 is a diagram showing the contents of a word dictionary according to an embodiment, in which the pronunciation, spelling, and part of speech of each word are stored. FIG. 8 is a diagram showing the contents of a part-of-speech connection table according to an embodiment, which describes whether a front word and a post-word are grammatically connected and can form a constituent element of one clause. In the figure, ◯ indicates that connection is possible, and × indicates that connection is not possible. In the following, it is assumed that the kana-kanji conversion is performed based on the method of minimizing the number of clauses. For input of "tokacho", word dictionary 6
A word that is corrected using the first few characters of the input kana string is searched for, and the first word candidate shown in FIG. 9 is obtained. Next, referring to the part-of-speech connection table shown in FIG. 8 and the prefix grammar information storage section shown in FIG. 6, it is determined whether each candidate can be connected to the prefix word. As a result, it can be seen that only the case particle "to" can be connected to the preceding word as a constituent element of a clause. After that, kana-kanji conversion is performed sequentially using the conventional method. As a result, candidates for sentences containing kanji and kana as shown in FIG. 10 can be considered. Only in the case of the case particle ``to'' is it connected to the preceding clause, so the ``to'' part is not counted as the number of clauses. As is clear from FIG. 10, the candidate whose notation is "to section chief" has the smallest number of clauses, and is adopted as a candidate for kana-kanji conversion.

Therefore, the document display result shown in FIG. 11 is obtained.

Even if the kana-kanji conversion method is another method such as the two-clause longest match method, "to section chief" can be selected in the same way.

As described in detail, the present invention enables, when inserting a character into a sentence containing kana and kanji that has already been input, the character string immediately before the insertion position and a plurality of candidates corresponding to the input kana. Refer to the priority of connections with each kanji using a table,
Since candidate kanji with a high priority in connection relation are output, it is possible to provide a kana-kanji conversion device with less possibility of erroneous conversion.
