Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a character conversion device that converts a first character into a second character, that is, performs kana-kanji conversion (or romaji-kanji conversion).
The present invention relates to a character conversion device equipped with a user dictionary that can be arbitrarily created.

<Prior art> There are various methods for kana-kanji conversion (or romaji-kanji conversion) devices generally used in Japanese word processors. This kana sentence is supplied to a conversion dictionary and converted into kanji or a sentence mixed with kanji.

For this reason, the dictionary stores the kana heading of one clause or word as described above, and the corresponding kanji or sentences mixed with kanji, in pairs. That is, the dictionary stores independent words and sentences with kanji mixed in with conjugated forms, word endings, etc. added to them in correspondence.

Therefore, for example, a compound word such as "Japanese economy" must be converted separately for each independent word. In this example, it was necessary to input "Nihon" to convert it, and then input "Keizai" to convert it.

For this reason, it would be ideal to store a series of words such as compound words or phrases as mentioned above in a dictionary, but in this case, the capacity of the dictionary would become enormous and the conversion processing speed would slow down. There is a problem.

Therefore, it has been proposed to have a fixed dictionary memory made up of a mask ROM or the like in which a predetermined number of words are registered, and a user dictionary memory that can be created independently by the user (separate from the fixed dictionary memory). .

This user dictionary is created by registering headwords arbitrarily set by the user and corresponding kanji or kanji-mixed sentences for words such as compound words and compound words. By setting the headword as “Nihon” and registering “Nihon Keizai” corresponding to this headword,
By simply inputting ``Nihon'' in kana, it can be converted into ``Japanese Economy'' at once.

By using such a user dictionary memory, it is possible to register the user's favorite dictionary, that is, the words and phrases such as compound words and idioms that the user uses relatively often. Conversion processing can be done quickly.

However, this user dictionary memory allows users to freely create dictionaries by registering words and phrases as they wish.For example, if multiple people use the device, they will have to create user dictionaries for each individual, and as a result, various Similar words will be registered in a complicated manner.

For example, as shown in Figure 1, user A registers "Japanese word processor" with the headword "Nihon", and user B registers "Japanese economy" with the headword "Nihon". Furthermore, user C may register "Bank of Japan" with the headword "Nihon".

In this case, when user C inputs "Nihon" in this user dictionary memory, the words and phrases that have the input "Nihon" as a headword, that is, the words and phrases that are candidates for conversion, are "Japanese word processor", " ``Japan Economy'' and ``Bank of Japan,'' and it was necessary to output these candidate words in sequence. In other words, the number of candidates for conversion increases and the time required for conversion processing increases.

In other words, the current situation is that user dictionaries are not used efficiently in conventional devices.

<Objective> The present invention relates to a user dictionary memory having the above-mentioned problems, and is an improvement to enable efficient conversion processing.

In particular, when creating a user dictionary, registered words include information about the creator of the dictionary, such as the creator's name or the name of the section to which the creator belongs (general affairs, sales, etc.)
etc., and by searching the user dictionary memory from the kana input characters and the creator information during the conversion process, it is possible to efficiently convert the desired words.

<Example> FIG. 2 is a block diagram showing one embodiment.

Reference numeral 1 denotes a keyboard device, which includes character keys such as kana character input keys and alphabet keys for inputting Roman characters, and various control keys for text editing.

Typical control keys are listed here: (1) Conversion keys that instruct the conversion of input kana text to the corresponding kanji or kanji-mixed sentences (conversion sentences); (2) Instructs to read other conversion sentences. Next candidate key, (3) User dictionary creation mode key for creating a user dictionary, (4) Instructs whether or not to register creator information in the user dictionary, and determines whether or not to use the creator information when reading converted sentences from the user dictionary. Switch SW, etc. where instructed.

When a key of the keyboard device 1 is operated, the key signal is encoded by the key control section and supplied to the editing control section 2 via the bus line 9. The editing control section 2 is composed of a μ-CPU.

3 is a RAM, which consists of a program area 31 for storing an editing program and a data area 32 for configuring various buffers, flags, etc. used during editing processing. The editing program stored in the program area 31 is stored in the floppy disk device (FD) 6 when the device is powered on.
It is loaded from .

Further, as various buffers in the data area 31, the following buffers are particularly provided.

(1) A kana buffer that stores kana sentences supplied from the keyboard device 1; (2) A kana buffer that stores converted sentences read from a fixed dictionary memory or a user dictionary memory, and stores the data in a display device or a disk memory built in the device. (3) a creator information buffer that stores dictionary creator (or user) information (in this example, the user's individual code information);

The dictionary creator (or user) information to the creator information buffer is written, for example, in advance into a system file on a floppy disk for personal use, and when the system file (editing program) is loaded from the disk. The above information may also be loaded and stored, or code information may be input and stored from the keyboard device 1 when the device is used to create a text.

4 is a fixed dictionary memory composed of a mask ROM, and is a conversion dictionary known for general kana-kanji conversion. That is, the dictionary stores headwords in reading kana and converted sentences or grammatical information corresponding to these headwords in pairs. Therefore,
The reading control of this dictionary memory 4 is carried out by the editing control section 2.
When a kana sentence is supplied to the dictionary memory 4, the headword in the memory 4 is searched, a headword corresponding to the supplied kana sentence is selected, and a converted sentence is output to the selected headword. It's summery.

5 is a magnetic disk device built into the device, and a user dictionary area (user dictionary memory) 51
and a text area 52 for storing created texts.

As shown in FIG. 3, the user dictionary area 51 includes a headword area 51A and a converted sentence area 51.
B, and a creator information area 51C.

The creator information area 51C contains the user's code information (the kanji code of the user's name or the unique
ID code) is stored in combination with the headword and converted sentence.

Here, the switch of the keyboard device 1 mentioned above is
To explain the relationship between SW and creator information, when registering to the user dictionary memory 51 (when creating a dictionary), if the switch SW is OFF, it instructs to register to the creator information area 51C, and when the switch SW is ON. nu11 instead of author information in state
This is an instruction to register the code in the area 51C and not to specify the creator.

On the other hand, when the switch SW is in the OFF state during conversion processing by the user dictionary memory 51, it instructs to search for the creator information registered in the user dictionary memory 51, and when the switch SW is in the ON state, the search is performed regardless of the creator information. This is an instruction to do.

In FIG. 1, 7 is a CRT display device, and 8 is a printer.

Next, a series of operations of the above-mentioned apparatus shown in FIG. 1 will be explained together with the operation flows shown in FIGS. 4 and 5.

() Creating a user dictionary (see the flowchart in Figure 4) First, turn on the power to the device, load the system file disk into the FD device 6, and the editing control program will be loaded from the FD device 6. It is introduced into the program area 31 of RAM3.

Further, if the creator information is registered in advance on the disk board of the system file, the creator information is introduced into the creator information buffer configured in the data area 32 of the RAM 3. This creator information may be input from the keyboard device 1.

Next, when you operate the user dictionary creation mode key on the keyboard device 1 to set the mode,
Thereafter, the control is performed to execute the flow shown in FIG.

In creating a user dictionary, first, a kana sentence is inputted from the keyboard device 1 as a headword of the user dictionary. This kana sentence is introduced into the kana buffer configured in the data area 31 of RAM3. This input kana sentence is displayed on the CRT display device 7.

When the input of this headword is completed (for example, a completion instruction is given), the data of the Kanabashua is sent to the user dictionary memory 51 and stored at the new registered address of this headword area 51A.

That is, in the initial state where nothing is registered in the user dictionary memory 51 yet, it is stored at the first address of the headword area 51A. In the example shown in Figure 3, the entry word "Nihon" is entered in kana, and in the initial state, the entry word area 51 is
It is stored at the first address of A.

Next, when the user inputs the pronunciation of the converted sentence to be registered again from the keyboard device 1, this kana sentence is introduced into the kana buffer and displayed on the CRT display device. Thereafter, based on the conversion instruction, a converted sentence corresponding to this kana input is read out from the fixed dictionary memory 4 and stored in the output buffer.

The conversion statement read into this output buffer is
It is displayed on the CRT display device 7. mentioned above
It is preferable that the message be displayed on the CRT display device 7 together with the previous headword in a message area set at the bottom of the CRT display screen, for example.

The converted sentence to be registered is generally a special word such as a compound word or an idiom. Therefore, the fixed dictionary memory 4 is used for the conversion operation in multiple times, and one registered converted sentence is obtained by combining the converted sentences. In the example of FIG. 3, "Japanese word processor" is shown as the registered conversion sentence.

In this way, when the creation of the converted sentence to be registered is completed (for example, a completion instruction is given), this converted sentence is stored in the converted sentence area 51B of the user dictionary memory 51 as a pair with the headword "Nihon". be remembered.

Following this, it is determined whether the switch SW is ON or not, and if the switch SW is OFF, this is an instruction to register the creator information, so
The data of the creator information buffer is stored in the creator information area 51C of the user dictionary memory 51 in a pair with the converted sentence.

In the example of FIG. 3, the creator information is a code indicating the creator name "Tanaka", and "Tanaka" is registered in the area 51C.

Also, when the switch SW is in the ON state,
Since this is an instruction not to register the creator, a nu11 code is written in the corresponding position of the creator information area 51C.

A user dictionary is created in this way, and in the example of the user dictionary memory shown in Figure 3, the creator "Suzuki" has registered "Japan Economy" as the headword "Nihon", and the creator "Yamamoto" ” is the headword “Nihon” and “Japanese WP” is registered, and without registering the creator (turn on the switch SW above), the headword “Nihon” is registered.
``Bank of Japan'' is registered as ``Bank of Japan.''

() Conversion processing using user dictionary (see flowchart in FIG. 4) When a kana sentence to be converted is input from the keyboard device 1, it is stored in this kana buffer. At this time, this kana sentence is displayed on the CRT display device 7.
displayed in the text display area. Then, a conversion instruction is given using a conversion key into which a predetermined kana sentence is input.

In response to this display, the data of the canada buffer is supplied to the user dictionary memory 51. That is, the user dictionary memory 51 has priority over the fixed dictionary memory 4, and the user dictionary memory 51 has priority over the fixed dictionary memory 4.
A search is performed for the headword corresponding to the kana sentence input. And the dictionary memory 5
If there is no headword corresponding to No. 1, the search proceeds to the fixed dictionary memory 4.

In searching the user dictionary memory 51,
When the corresponding entry word is detected, for example, if "Nihon" is input in kana in the above example, "Nihon" is included in the entry word in the user dictionary memory 51, so this will be detected.

That is, when searching the user dictionary memory 51 in FIG. 3, for the kana input "Nihon", the headword "Nihon" at the beginning of the memory 51 is detected.

Here, the device creator information is “Tanaka”
is held and the switch SW is turned OFF and there is a search instruction based on the creator information.Subsequently, it is determined whether the creator information area 51C corresponding to the detected headword is a nu11 code. In this example, "Tanaka" is registered in area 51C, so the nu11 code is not detected.

If the nu11 code is not detected, it is subsequently determined whether the information held in the creator information buffer matches the creator information in the area 51C. In this example, since "Tanaka" is included in the buffer and "Tanaka" is written in the area 51C, the converted sentence "Japanese word processor" is read out to the output buffer and displayed on the CRT display device 7. Ru.

Therefore, in this case, if you input "Nihon", it will be converted to "Japanese word processor".

Also, if "Nihon" is entered while "Suzuki" is held in the creator information buffer, it will be converted to "Japan Economy". In this case, the creator information for the headword "Nihon" at the first address is "Tanaka" and does not match the creator information buffer "Suzuki", so the next address with the headword "Nihon" is selected. , the above-mentioned "Japanese Economy" is read out based on the detection of a match with the creator information "Suzuki" at this address.

Note that the reason why the nu11 code is detected in advance is that the converted sentence with the nu11 code is read out regardless of the creator information, so the third
In the above example of the figure, when the author name is set to "Tanaka" and the kana input is "Nihon", the conversion candidates for "Japanese word processor" and "Bank of Japan" are the conversion candidates. Since it is detected from the address, the converted sentence "Japanese word processor" is read out first. Then, when the next candidate instruction key is operated when this is not the desired converted sentence, the converted sentence "Bank of Japan" will be read out.

On the other hand, if the above-mentioned switch SW is in the ON state, the search is not based on the creator information, so for the kana input "Nihon", "Japanese word processor", "Nihon Keizai", "Bank of Japan", " Japan
WP” becomes a conversion sentence candidate.

Note that although the above embodiment describes kana-kanji conversion, it can be similarly implemented for Romanji-kanji conversion or from kana or Roman characters to English.

<Effects> As described above, the present invention includes a character conversion device that converts a first character given in Kana characters or Roman characters into a second character such as a Kanji character or a sentence containing Kanji characters corresponding to the first character. Tokoro user (user)
For user dictionaries that can be registered and created at will, the entry word given by the first character, the converted word or converted sentence given by the corresponding second character, and the registered creator of this converted word or converted sentence. or creator information indicating its attribution, etc., are stored as a pair, and the user dictionary is searched using both the headword and creator information during conversion processing using this user dictionary. It has the characteristics that conversion processing into a target word or sentence can be performed at high speed, and processing using the user dictionary can be performed efficiently.
