PURPOSE:To improve the efficiency of Japanese syllabary conversion and to improve the operability of the device by counting the number of keywords included in a sentence inputted in Japanese syllabaries for each field based on a keyword dictionary, determining the field to which most of the number of the keywords belong as the field of the input sentence and giving the first conversion priority order to Chinese character candidates in the field in a Chinese character dictionary. CONSTITUTION:A Japanese syllabary/Chinese character conversion part 2 extracts keywords stored in a keyword dictionary 5 for each field as the keywords characterizing the respective field from an original sentence inputted from a Japanese syllabary input part 1 of a keyboard or the like, counts the number of the extracted keywords and determines the field to which most of the number of the keywords belong as the field of the input sentence. In a Chinese character dictionary 3, the respective Chinese character candidates, their priority order and the field they bolong to are stored. The Japanese syllabary/Chinese character conversion part 2 converts the Japanese syllabary in the input sentence into the Chinese character candidate having high priority order in the determined field of the input sentence, and outputs the sentence expressed in Japanese syllabaries and Chinese characters utilizing the Chinese character selected by an operator to a Japanese syllabaries/Chinese characters mixed sentence output part 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kana-kanji conversion device for converting a kana input Japanese sentence into a kanji-mixed sentence according to the field.

[0002]

2. Description of the Related Art In a kana-kanji conversion device such as a Japanese word processor with many homophones, kanji candidates corresponding to Japanese that are kana-input from a keyboard are selected in accordance with the operator's conversion keys or kanji dictionary keys. The characters are displayed one after another, but the priority of the conversion is predetermined according to the frequency of appearance of Chinese characters.

Generally, in the kana-kanji conversion device, the conversion priority is fluid in order to efficiently convert kanji,
For example, by analyzing the syntactic and semantics to prevent meaningless combinations of Kanji, changing the priority of recently converted Kanji to the highest, or the priority of the user dictionary created individually by the user. According to the above, or according to the designation of fields such as chemistry, medicine, and mathematics by the operator, the priority order is changed using the dictionary in which the priority level is determined for each designated field.

FIG. 1 is a block diagram showing the configuration of a conventional kana-kanji conversion device, in which a kana-kanji conversion unit 2 converts the original text input from a kana input unit 1 such as a keyboard into a predetermined conversion priority order. It is converted into a kanji character read from the kanji dictionary 3 in the order based on, and the kanji-converted kanji mixed sentence is output to the kanji mixed sentence output unit 4.

FIG. 2 is a flow chart showing a procedure for converting kana-kanji characters by a conventional kana-kanji conversion device. When a kana original sentence is input from the input unit (S1), the kana original sentence is divided into words and morphological analysis is performed to determine each part of speech (S2), and the syntax and meaning are analyzed (S3). next,
Kanji is determined according to the analysis result and converted into Kanji (S4),
A mixed kanji sentence is generated (S5).

[0006]

In the conventional kana-kanji conversion device as described above, it is possible to change the conversion priority set in the device. For example, in order to create a user dictionary, each word Is required to be registered, and the burden on the user side increases. In addition, when specifying a field when inputting a kana original text, the priority order for each field cannot be used unless the field of the original text can be determined. Furthermore, when the field of the original text changes in the middle, not only the priority of the field originally specified is not utilized but also the conversion efficiency is lowered.

The present invention has been made to solve the above problems, and automatically determines the field to which a Japanese sentence input in kana belongs, and according to the determined field, the kanji conversion priority order. The purpose of the present invention is to provide a kana-kanji conversion device with good operability by changing the.

[0008]

A kana-kanji conversion device according to the present invention corresponds to a kana-kanji conversion device for converting kana-input words into corresponding kanji candidates in the order corresponding to the conversion priority. The number of keywords extracted from the kana input sentence, the kanji dictionary that stores the kanji candidates and the priority of the conversion, as well as the kanji dictionary that stores the fields with high conversion rates into the kanji candidates, the keyword dictionary that stores the keywords that characterize each field And means for determining the field to which the sentence belongs,
And a means for changing the conversion priority of a kanji candidate having a high conversion efficiency in the field determined by the means to the highest rank.

[0009]

The kana-kanji conversion device according to the present invention counts the number of keywords contained in a kana-input sentence for each field based on the keyword dictionary, determines the field having a large number of keywords as the field of the input sentence, and determines the kanji dictionary. Change the conversion priority of kanji candidates in that field to the highest.

[0010]

The present invention will be described below with reference to the drawings showing the embodiments thereof. FIG. 3 is a block diagram showing the configuration of a kana-kanji conversion device according to the present invention (hereinafter referred to as the device of the present invention). The Kana-Kanji conversion unit 2 is a Kana input unit 1 such as a keyboard.
From the original text input from, the keywords stored in the keyword dictionary 5 as the keywords characterizing each field are extracted, and the number of extracted keywords is counted,
The field with the largest number is determined as the field of the input sentence.

The kanji dictionary 3 stores each kanji candidate as well as the priority and the field to which it belongs. Kana-Kanji conversion unit 2
Converts the kana of the input sentence into a kanji candidate having a high priority in the determined input sentence field, and outputs a kanji mixed sentence using the kanji candidate selected by the operator to the kanji mixed sentence output unit 4.

The operation of converting kana-kanji characters by the kana-kanji conversion device having the above configuration will be described with reference to the drawings. FIG. 4 is a flow chart showing the procedure of Kana-Kanji conversion, FIG. 5 is a conceptual diagram of a table for determining the field of an input sentence and a Kanji dictionary in the Kana-Kanji conversion unit 2, and FIG. 6 is a diagram showing a screen display example.

On the initial screen as shown in FIG. 6, when "field learning" which is a function of changing the field setting of the input sentence according to the number of keywords in the sentence is selected and data is input to the "field name", the input field is input. If no data is input, the conversion priority order shown in FIG. 5B stored in the Kanji dictionary is designated (S11).

When a Kana original sentence is input from the input unit (S1
2) Count the number of keywords in each field in sentence units or paragraphs, determine the number of keywords in each field as shown in Fig. 5 (a), and determine the priority order of the fields in descending order.
The conversion priority of conversion candidates in the Kanji dictionary shown in FIG. 5 (b) is changed according to the determined priority of the field (S).
13).

Next, the Kana original sentence is divided into words and morphological analysis is performed to determine each part of speech (S14), and the syntax and meaning are analyzed (S15). Next, the kanji is determined according to the analysis result and converted into kanji (S16) to generate a kanji mixed sentence (S17).

In this embodiment, as a result of counting the number of keywords at the time when the kana original sentence of one paragraph sentence is input without designating the field name, the fields up to that point are determined to be "general". Therefore, the priority of the kanji candidates for the kana called "Saiketsu" is "voting". For example, after this
If "medicine" is ranked first as a result of keyword judgment,
The conversion priority of "Blood collection" is first. If there is no conversion candidate for the applicable field, the Kanji candidate for the next field is selected.

If the history of the field determined for each sentence or paragraph is stored and the history is used when reading and editing the mixed kanji character after kanji conversion, the operator can edit the text. There is no need to judge the field again.

[0018]

As described above, the apparatus of the present invention determines the field to which the input Kana original sentence belongs, changes the conversion priority of the Kanji candidate according to the field, and gives priority to the Kanji candidate corresponding to the field of the Kana original sentence. Since the conversion is performed automatically, the rate of conversion to the optimum kanji candidate is increased, and it is possible to significantly reduce the work of correcting conversion errors in the sentence after kanji conversion.
