Abstract

PURPOSE:To improve operability by registering a reading and KANJI (Chinese character) as Chinese compound words in an internal dictionary when the KANJI defined by a single KANJI conversion is defined by the only KANJI having specific reading information. CONSTITUTION:In each record of single KANJI dictionary data stored in a dictionary area 72 of a ROM 70, the columns for a reading character string, a single KANJI corresponding to it and a flag showing whether the reading is a phonetic one or not are provided. When a conversion character string corresponding to an inputted reading character string does not exist in a Chinese compound word dictionary, the candidate of the conversion character string is searched, using the single KANJI dictionary. When a KANJI is defined by this signal KANJI dictionary retrieval, whether the reading at the time is a phonetic one or not is decided by a phonetic reading flag in the single KANJI dictionary. When the reading is the phonetic one, the reading and KANJI are temporarily stored in the working area 82 of a RAM 80. If the signal KANJI conversion is terminated by the only phonetic reading, the stored reading and KANJI are registered as the Chinese compound words in the dictionary registering area 86 of the RAM 80.

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 such as a Japanese word processor.

[0002]

2. Description of the Related Art Conventionally, a kana-kanji conversion device searches a idiom dictionary and outputs candidates for a conversion character string when a phonetic character string is input, and the kanji-kanji conversion dictionary is also used by the user. If there is no candidate for, the method is to search the single kanji dictionary and determine each kanji.
On the other hand, there is also a method in which the user can register a idiom that is not in the idiom dictionary by reading and specifying a conversion character string such as kanji.
In addition, JP-A-63-73465 and JP-A-61-7.
As shown in Japanese Patent Publication No. 7960, an apparatus for registering a compound word by synthesizing words in a phrase dictionary is considered.

[0003]

However, in the above kana-kanji conversion device, in order to convert a compound word that is not registered in the compound word dictionary, a single kanji character is applied one by one.
When the idiom is used frequently, it is necessary to convert each kanji into a single kanji each time it is input, which takes time and effort. By the way, compared to idioms, single kanji usually has many candidates for one reading. Especially in the case of phonetic reading, there are many numbers, so it is difficult to find the kanji you want. In addition, when user registration of compound words that combines single Chinese characters is interrupted when the document input work is stopped, there is a problem that the work efficiency of document creation is poor.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to use words that are not registered in the idiom dictionary.
When each kanji is confirmed by single kanji conversion, the kanji is registered as a idiom in the internal dictionary only when it is decided by specific reading information, such as "kanji reading" that has a high probability of becoming a idiom. The purpose is to

[0005]

In order to solve this problem, a kana-kanji conversion device of the present invention comprises an input means for inputting a reading character string and a conversion of the reading character string input by the input means into kanji and kana. A idiom dictionary for storing information necessary for converting into a character string, and a unit for storing information necessary for converting a reading character string input by the input means into a conversion character string of Kanji for each Kanji character. A kanji dictionary, a kana-kanji conversion means for converting the reading character string into the conversion character string by using the idiom dictionary or the single kanji dictionary, and reading kanji reading, kun reading, etc. for each kanji in the single kanji dictionary. The conversion character string having the information and corresponding to the reading character string input by the input unit is composed of a plurality of single Chinese characters not stored in the idiom dictionary, and the reading character string has a specific reading. When configured only kanji with broadcast, and a means for registering the idiom dictionary the converted character string as a phrase.

[0006]

In the kana-kanji conversion device of the present invention having the above configuration, when the input phonetic character string is converted, the corresponding conversion character string is not registered in the idiom dictionary, and single kanji characters are converted one by one by kanji conversion. If confirmed, the kanji will be registered as a idiom in the internal dictionary if the kanji has been decided only by the kanji that has specific reading information such as "Onyomi" that has a high probability of becoming an element of the idiom. Therefore, from the next time, when the same phoneme string is converted, it becomes a conversion candidate as a idiom.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

First, the structure of the entire kana-kanji conversion device 10 will be described with reference to FIG. A keyboard 20 for inputting a read character string and instructions, a display 30 for displaying characters and figures, a printer 40 for printing characters and figures, and a function connected to these to control input / edit / print of documents It is composed of an electronic control unit 50.

The keyboard 20 is a key for inputting characters, a key for converting an input character string into kanji, a line feed execution key for executing various operations such as selecting a conversion character string at the time of conversion, and a character in a document. Cursor keys for changing the input position are provided, and the user operates the keys to give instructions to the electronic control unit 50 for inputting, converting, editing, printing, etc., of the document.

The electronic control unit 50 includes a well-known CPU 60,
The ROM 70, the RAM 80, and the like are mainly configured as an arithmetic logic operation circuit, and an input / output port 90 for converting an input / output signal of an external device such as the keyboard 20 into a signal that can be processed by the CPU 60 is provided.

In addition to the area for storing the kana-kanji conversion processing program, the ROM 70 is provided with an area 72 for storing dictionary data such as a phrase dictionary and a single kanji dictionary used in this conversion processing.

In the RAM 80, an area 82 in which a created document is stored, a work area 84 used for kana-kanji conversion processing, and as will be described later, dictionary registration for registering idioms made by synthesizing single kanji A region 86 is provided.

An example of single Kanji dictionary data stored in the ROM 72 of this embodiment is shown in FIG.

In each record of the dictionary data, in addition to the reading character string and the single Chinese character corresponding thereto, a column of reading information, which is a feature of this embodiment, that is, whether the reading is a phonetic reading is indicated. There is a column for flags. That is, if the reading of the record is a phonetic reading, the symbol "!" Is set, and if it is a kun reading, it is blank.

Next, the kana-kanji conversion processing of this embodiment will be described with reference to the flowcharts of FIGS.

First, a reading character string to be subjected to kana-kanji conversion, for example, "jihanki" is input from the keyboard 20 (S100) and the conversion key is pressed (S110).
After searching the idiom dictionary and determining whether or not the connection between the conversion character strings is good (S120), candidates for the conversion character string are displayed on the display 30.

However, when the converted character string corresponding to the input phonetic character string does not exist in the idiom dictionary (S130,
N) or if there is no candidate required by the user even if it exists (S140, N), the cursor of the keyboard 20 or the like is used to shuffle the phrase of the reading character string (S150). Conversion character string candidates can be searched for using the Kanji dictionary (S160). Note that the phrase here is a group of character strings obtained by separating the character strings to be converted.

If "jihanki" in the example is not in the idiom dictionary and cannot be converted, the user first sets the reading character string to be converted to "ji", switches to single-kanji conversion, and presses the conversion key. . Then, the conversion candidates for the single kanji such as "self, thing, ..." Are displayed on the display 30, and "self" is selected from these.

When the kanji is determined by this single kanji dictionary search (S190), it is determined whether the reading at that time is the on-reading by the on-reading flag in the single kanji dictionary (see FIG. 2). If it is a phonetic reading (Y in S210), the reading and Chinese characters are temporarily stored in the work area 82 of the RAM (S220).

Next, it is judged whether or not there is a Kanji character stored immediately before (S230), and if there is any (S230,
Y), together with the immediately preceding kanji, it is temporarily stored in the work area 82 of the RAM (S240).

In the example of "jihanki", the conversion candidate of "self" is selected by reading "ji". In this case, since "ji" has a phonetic reading flag, the reading and Chinese characters are temporarily stored. There is no kanji that was fixed immediately before, so just remember it as "ji: yourself".

If the reading character string to be converted still remains (S250, N) (S270, N), the cursor is moved to the next reading character string to be converted (S28).
0), the above conversion is repeated (S110-).

In the example of "jihanki", the same conversion is performed for the next reading character string after the previously determined "ji: own". Suppose that the phrase is moved to the next "hanki" reading string. Even if you press the conversion key, "Hanki" appears in the idiom dictionary.
Since the conversion character string corresponding to is only "half term", "rebellion", etc., move the phrase to "han" and press the conversion key. Like the candidates shown in FIG. 2, candidates are displayed as “half, counter, sales, ...”, and “sales” is selected from these candidates. Since the phonetic reading flag is set for this kanji reading "han", the reading and kanji "han: sales" are temporarily stored. Since “Ji: Self” that was confirmed immediately before is stored, it is also temporarily stored as “Jihan: Self-sales” together with it.

Further, the phrase to be converted is moved to "ki" of "jihanki" and converted. As a candidate "tree, note, machine,
... "is displayed, and" machine "is selected from these. The reading "ki" at this time also has an on-reading flag, so
The character string “Jihan: Self-sales” that has been finalized and stored
It is also stored as "Jihanki: Vending machine".

If the conversion of single kanji is completed only by reading the sound (S
250, Y), the stored reading and kanji are registered as idioms in the dictionary registration area 86 of the RAM (S26).
0).

Since "vending machine" is stored in the dictionary registration area by reading "jihanki", next time you enter "jihanki" and the reading character string and press the conversion key, "vending machine" will be the first It will come out as a candidate.

As described above, a word that is not registered in the idiom dictionary can be converted into a candidate by single kanji, and the converted character string converted by the single kanji is read into the internal dictionary by reading at that time. By registering as an idiom, the candidate can be first put out as an idiom when the same reading character string is converted next time. Therefore, there is no need to re-phrase and convert each kanji character, the number of key operations on the keyboard can be reduced, and the operations that hinder the user from writing the text can be reduced, making it easier to use. Become.

The reason why the reading is limited to on-the-speech reading is that Chinese is excellent in coinage and has the property of becoming a very idiom. Also,
There are usually many kanji candidates for each reading such as "ki" and "kan", and different kanji are frequently used for various idioms. No matter how much the learning function is equipped, it is very troublesome to choose one from the many kanji. Therefore, if it is registered as an idiom as in the present invention, it is possible to save the trouble of selecting one kanji from many candidates when the next conversion is performed.

The present invention is not limited to what has been described in detail above, and various modifications can be made without departing from the spirit of the invention. For example, in the present embodiment, the reading information is composed of phonetic readings, but it is also possible to use kun readings as shown in the following example.

For example, in Japan, there are relatively many readings for surnames, names, and place names of people. Therefore, especially in kun reading, a person name flag that is used for a person's name is provided in the single kanji dictionary, and if the combination of single kanji characters having that person name flag is registered as a idiom. Yes, some applications can be expected.

Further, in the present invention, the phrase dictionary is provided in the ROM area and the phrase registration area for newly registering is provided in the RAM area. However, both of them may be provided in the RAM area. Can also be configured as a idiom dictionary in one RAM area.

[0032]

As is apparent from the above description,
The kana-kanji conversion device of the present invention, when converting words that are not registered in the idiom dictionary into single kanji characters one by one, if the reading has specific reading information such as on-reading, the internal dictionary. Since it is registered as a idiom in, the next time you convert the same reading character string, candidates will appear as idioms, so
There is no need to shuffle the clauses and convert one kanji each time the same character string is converted. This leads to a reduction in the number of key operations on the keyboard and a reduction in the movements that hinder the user from writing the text itself, and is easy to use.
