Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kana-kanji conversion device such as a Japanese word processor for converting kana characters into kanji in a character string mixed with kanji or kana input by handwritten character recognition or the like. .

[Conventional technology]

When a conventional Kana-Kanji conversion device converts Kana-Kanji characters, a kanji dictionary is searched to display all the kanji that read the kana to be converted as a conversion candidate in a list on the screen, or the conversion keys are sequentially displayed each time a conversion key is pressed. Conversion kanji has been selected.

[Problems to be solved by the invention]

By the way, in Japanese, there are a large number of homonyms such as, for example, about 300 readings of “ko”. Therefore, every time the kana to kanji conversion is performed, the operator has to visually check a large number of displayed kanji candidates and select the kanji to be converted, and there is a problem that the kanji conversion operation is complicated and the efficiency is low.

The present invention has been made to solve such a problem, and provides a kana-kanji conversion device in which the operation of kana-kanji conversion is simplified and the operation efficiency is high by narrowing down the number of kanji to be output as conversion candidates. Aim.

[Means for solving the problem]

The kana-kanji conversion device of the present invention is a kana-kanji conversion device that converts a kana designated as a conversion target into a kanji,
A kanji dictionary that stores kanji, a idiom dictionary that stores kanji of idioms, a unit that reads kanji that reads kana to be converted from the kanji dictionary, and a series of read kanji and kana characters to be converted Means for searching for a word synthesized with a character to be converted in a idiom dictionary, and means for selecting a kanji to be converted from the read kanji in accordance with the frequency of occurrence of the word in the idiom dictionary as a result of the search. It is characterized by having.

[Action]

The kana-kanji conversion device of the present invention reads a kanji reading a kana specified as a conversion target from a kanji dictionary, and combines a word obtained by synthesizing the read kanji and a character continuous with the kana character to be converted into a phrase dictionary. A search is performed, and as a result of the search, the frequency at which the synthesized word appears in the idiom dictionary is checked, and the kanji to be converted is selected from the kanji read from the kanji dictionary according to the frequency of occurrence.

〔Example〕

Hereinafter, the present invention will be described with reference to the drawings showing the embodiments.

FIG. 1 is a block diagram showing the configuration of a kana-kanji conversion device according to the present invention. In FIG. 1, reference numeral 1 denotes a character string input unit such as an OCR for optically reading handwritten characters. The control unit 2 temporarily stores the input character string in the text storage unit 3,
Is displayed on the display unit 4. A character string specifying unit 5 composed of a keyboard or the like specifies a character specified as a conversion target by an operator as an editing target such as kana-kanji conversion, and the specified character is displayed on the display unit 4 with a cursor so as to be distinguishable from other characters. Is displayed in.

The kanji candidate creation unit 6 is a kanji dictionary 7 that stores kanji.
The kanji which reads the character to be converted is read out from, and written in the kanji candidate table 8 as a conversion candidate. The kanji candidate table 8 includes a kanji area 8a in which kanji candidates read from the kanji dictionary 7 are written and a score area 8b in which the frequency at which each kanji candidate appears in the idiom dictionary 10 described later is stored.

The idiom candidate creation unit 9 searches the idiom dictionary 10 that stores the kanji of idioms for a word that combines the kanji candidate written in the kanji candidate table 8 and the characters before and after the character to be converted, and synthesizes the word. When the word appears in the idiom dictionary 10, the word is added to the score area 8b of the kanji candidate table 8, and the kanji candidate with the highest score is written in the conversion candidate table 11. Conversion output section
Numeral 12 outputs the kanji candidates written in the conversion candidate table 11 to the display unit 4 or the like.

Next, the procedure of kanji conversion by the kana-kanji conversion apparatus having the above-described configuration will be specifically described.

2 and 3 are conceptual diagrams showing the storage state of the kanji candidate table 8, FIG. 4 is a conceptual diagram showing the storage state of the word dictionary, and FIG. 5 is a conceptual view showing the storage state of the idiom dictionary.

A character string mixed with kanji or kana entered by the character string input unit 1,
"Teacher, which has thing over Fu newly, to take advantage of the new cans line was business trip to Tokyo" Search and underlined portion of the "fu" is specified as the target of the kana-kanji conversion, the kanji candidate generating unit 6 is kanji dictionary 7 And the kanji reading "fu"
"Step" is written in the kanji area 8a of the kanji candidate table 8 as shown in FIG. 2, and the score area 8b is cleared to "0". If there is no corresponding kanji candidate as a result of the search, the kana character string is written to the conversion candidate table 11 as a conversion candidate. The idiom candidate creation unit 9 searches the idiom dictionary 10 for a word “husband” obtained by synthesizing the first kanji candidate “husband” in the kanji candidate table 8 and the character “ro” immediately after “fu”. As a result of the search, the corresponding idiom does not appear. Therefore, the idiom dictionary 10 searches the kanji candidate table 8 for the next word “women” composed of the kanji candidates “women” and “to”. As a result of the search, the corresponding idiom does not appear, as in the previous case. Therefore, the idiom dictionary 10 searches the kanji candidate table 8 for the word “post” composed of the next kanji candidates “post” and “ro”. As a result of the search, since the phrase appears as a phrase, the number of kanji “2” of the phrase is added to the score area 8b corresponding to “go”. In the same manner, the score of a word obtained by combining all the kanji candidates up to “step” and “ro” is calculated.

Next, a word “kuo”, which is a combination of the character “ku” immediately before “fu” and the first kanji candidate “husband” in the kanji candidate table 8, is searched in the phrase dictionary 10 and In the same manner as in the above-described case, the compound word with all the kanji candidates is written in the idiom dictionary 10
Search by and add points.

Further, a word “kuo-honin”, which is a combination of the character “ku” immediately before “fu” and the first kanji candidate “husband” in the kanji candidate table 8 and the character “ro” immediately after “fu”, is written in the phrase dictionary. Search by 10. Hereinafter, similarly, the characters before and after the conversion target,
A word obtained by synthesizing all the kanji candidates in the kanji candidate table 8 of the character to be converted is searched in the idiom dictionary 10, and if it appears as a idiom, the number of kanji of the idiom is added as a score.

The idiom candidate creation unit 9 writes the kanji candidate that obtained the highest score as a result of the addition as described above, in this embodiment, “go” in the conversion candidate table 11. If there are a plurality of kanji candidates that have obtained the highest score, the plurality of kanji candidates are written in the conversion candidate table 11, and if the scores of all the candidates are "0", all the kanji candidates are converted into the conversion candidate table 11. Write to.
The conversion output unit 12 outputs the conversion candidates written in the conversion candidate table 11 to the display unit 4.

In addition, "Teacher, which has thing over Fu newly, new cans line using was business trip to Tokyo" If you want to Kanji conversion underlined the "cans" of, as a result of the same steps as "Fu" of the above-mentioned, the first 3
Scores are obtained as shown in the kanji candidate table 8 shown in the figure, and the idiom candidate creation unit 9 writes the kanji candidate “stem” with the highest score into the conversion candidate table 11.

In the case of the present embodiment, 78 kanji candidates for "fu" are narrowed down to one, and 166 kanji candidates for "kan" are narrowed down to one, so that the selection operation is unnecessary.

In this embodiment, one character immediately before and immediately after the character designated as a conversion candidate is set as a search target.
The same effect can be obtained even when characters or more are searched.

Further, in the present embodiment, the number of kanji of idioms is added as a score. However, the present invention is not limited to this, and the same effect can be obtained by counting the frequency of appearance.

〔The invention's effect〕

According to the kana-kanji conversion device of the present invention, the number of kanji outputted as conversion candidates when converting kana to kanji is reduced and, in some cases, is reduced to one, so that the operator's selection operation in kana-kanji conversion is simplified. It has an excellent effect.
