Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kana-kanji conversion method for performing kana-kanji conversion by analyzing a kana character string in a dictionary.

[0002]

2. Description of the Related Art In the conventional method, as shown in FIG. 5, when a kana character "fu" is inserted into a character string "this is the correct answer" which has undergone kana-kanji conversion, the character is inserted. The dictionary analysis is performed only with words, or as shown in FIG. 6, the phrase or sentence once converted is returned to a kana and then the phrase or sentence is converted.

[0003]

In the method of FIG. 5, since the dictionary analysis is performed only with the inserted word, it is not always necessary to perform the conversion as expected at one time, and it is often necessary to perform the conversion many times. Further, in the method of FIG. 6, since the dictionary analysis can be performed by adding words before and after the inserted word, the conversion rate can be improved, but the work of once converting the sentence into the pseudonym before conversion is required.

The present invention has been made in consideration of such circumstances, and provides a kana-kanji conversion method for improving conversion efficiency by performing dictionary analysis by adding words before and after an inserted word. is there.

[0005]

SUMMARY OF THE INVENTION According to the present invention, in a document processing device configured to lexically analyze an input kana character string and convert it into a kana kanji mixed sentence, a character string converted into a kana kanji mixed sentence. (EN) A kana-kanji conversion method characterized in that when a new kana character is inserted into, a dictionary analysis is performed including the characters before and after the inserted character.

[0006]

[Function] Even when a new kana character is inserted in the character string converted into the kana-kanji mixed sentence, the dictionary analysis is performed including the characters before and after the inserted character. The conversion operation becomes easy because there is no need to return the converted Kanji to Kana characters.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. This does not limit the invention. FIG. 1 is a block diagram of a word processor according to an embodiment of the present invention. In the figure, reference numeral 1 is a character keyboard, and on this keyboard 1, kana keys and numeric keys are arranged.

A key signal input by operating the keyboard 1 is given to the encoding circuit 3. A key signal from the function keyboard 2 is further input to the encoding circuit 3.

The keyboard 2 is provided with an edit control key. The edit control key is a conversion key for instructing conversion of kana characters into kanji or kanji mixed sentences, a non-conversion key for instructing not to convert kanji, It has a front candidate key, a cursor movement key, an execution key, a cancel key, a cancel key, a special function key for mode setting, and the like.

The encoding circuit 3 encodes the key signals of the keyboards 1 and 2 to temporarily store the character data (character code) in the input buffer 4, and the encoded signals of the respective keys included in the keyboard 2 to the central processing unit ( Direct input to CPU) 5. The CPU 5 functions as an arithmetic processing unit by executing an operation program described later, and has a kana-kanji conversion function, a writing function, and a reading function.

A CRT display 6 and a printing device (printer) 7 are connected to the CPU 5. The CRT display 6 is used to display a kana input sentence and a converted kanji or kana mixed sentence.

The printer 7 is used to print kana or kanji mixed sentences. Further, the CPU 5 is connected with a conversion processing unit 8, a sentence data memory 9, and a Kana-Kanji conversion dictionary unit 10. The conversion processing unit 8 works together with the CPU 5 as Kana-Kanji conversion means.

The sentence data memory 9 stores the kanji mixed sentence input from the keyboard 1 and converted by the conversion processing unit 8 as sentence data. The kana-kanji conversion dictionary unit 10 is composed of, for example, a read-only memory (ROM) and the like, and includes a storage area for storing a word dictionary, a storage area for storing an inflection table, and a storage area for storing an auxiliary word table.

In this word dictionary storage area, kana heading parts in the order of Japanese syllabary, kanji writing parts corresponding to the kana heading parts, and part-of-speech data are stored. The kanji notation part stores the word stem part and the unchanged part. Next, the operation in such a configuration will be described with reference to the flowcharts shown in FIGS.

FIG. 2 shows a kana-kanji conversion operation when the kana input from the keyboard 1 is converted and the result (kana-kanji mixed sentence) is displayed on the CRT 6. First, after inputting a kana (step 101), kana-kanji conversion is started by the conversion key (step 102). Morphological analysis is performed to classify the input kana into prefixes, independent words, suffixes, inflections, adjuncts, etc., and the bunsetsu segmentation position is determined for each morpheme (step 103).

Next, each analyzed morpheme is converted into a kanji mixed sentence with reference to a dictionary (step 10).
4, 105). In this state, the kanji has not been decided yet, and another conversion result is displayed by further changing to a homonym or a delimiter of the phrase by the conversion key (step 108) (these methods are known. Can be used.).

After that, the confirmation is made by pressing a predetermined key (steps 106 and 107). Further, it is returned to the kana in units of clauses or sentences by using the cancel key or the like (steps 109 and 110).

By the way, in step 105, the display is a kana-kanji mixed sentence, but since it has not been confirmed yet, the word processor is first shown in FIG. 4 so that the kana can be restored. It stores the input kana data, morphemes, segment breaks, etc. Therefore, based on these data, the insertion word and the morphemes before and after the position where the insertion word is added are combined, morphological analysis is performed again, and a new kana-kanji mixed sentence is corrected by referring to the dictionary.

The operation of this part is shown in FIG. now,
For example, when "This is a result" is input (step 201), it is classified as "this is a result / is" by morphological analysis (step 202). Here, “/” indicates a segment break.

Next, referring to the dictionary, sentence data "This is the correct answer" is generated (step 20).
3). However, at this point, it has not been finalized yet, so the result of the morphological analysis is
The phrase break, reading information and morpheme data still remain.

When a kana called "fu" is added here (step 204), the connection between the inserted word and the words before and after it is analyzed based on the result of step 203. In other words, a) "This is Fu / Sekai I / Aru" b) "This is / Fu Seikai / Aru" c) "This is Fu / Sekai I / Aru" i) is the character string entered later Is attached to the previous phrase data, b) is a case where the character string input later is attached to the latter phrase data, and c) is a case where the character string input later constitutes a phrase by itself.

The conversion "this is an incorrect answer" is performed by referring to these and the dictionary. Here, "fu" added to the kana that was just input is added, and "This is a fuzekai" is not performed from the beginning, and if the input character is the bunsetsu delimiter position, the processing of a) -ha) Do. This is because the phrase break intended by the user is used by adding "fu" to the result (word break) of step 203.

[0023]

According to the present invention, even if a new character is inserted in the character string, the dictionary analysis is performed including the characters before and after the inserted character, so that the kana-kanji conversion operation can be efficiently performed.
