Abstract

PURPOSE:To perform efficient conversion processing by a registering a group of an index word, conversion word, and generating operator information in the 2nd dictionary, and using both pieces of the index word and generating person information during the conversion processing for retrieval in the dictionary. CONSTITUTION:When a user dictionary 51 is generated, ''nihon'' in KANA (Japanese syllabary) as the index word is inputter from a keyboard device 1 and registered in an area 51A of the dictionary 51. Then, the rendering KANA of a conversion sentence is inputted and then the conversion sentence is read out of a fixed dictionary 4 by a conversion indication and stored in an area 52 of the dictionary 51 in a pair with the index word. Then, the generating operator information ''Tanaka'' is stored in an area 51C of the dictionary 51 in a pair with the conversion sentence with a switch SW off. The ''nihon'' in the area 51 is detected firstly in the retrieval in the dictionary 51, and the ''Tanaka'' in the area 51C is then detected. Consequently, when the ''nihon'' is inputted on from the device 1, the conversion sentence ''Japanese word processor'' is obtained.

Description

[Detailed Description of the Invention] Technical Field> The present invention relates to a character conversion device for converting a first character into a second character (or Romaji-Kanji conversion). ) relates to a character conversion device equipped with a user dictionary that can be created arbitrarily.

<Prior art> There are various methods for kana-kanji conversion (or romaji-kanji conversion) devices generally used in Japanese word processors, but one method is to input kana sentences by dividing them into clauses or words, Sentences are supplied to a conversion dictionary and converted into kanji or kanji combinations.

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.

In other words, as a dictionary, it has independent words and conjugated forms.

Kanji characters with endings added are stored in correspondence.

Therefore, for example, a compound word such as ``Japanese economy'' must be converted separately for each independent word. In this example, I had 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 be enormous and the conversion processing speed would be slowed down. There's a problem.

A device has been proposed that includes a fixed dictionary memory configured with a 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 separately from the fixed dictionary memory.

This user dictionary contains headwords arbitrarily set by the user and 1
, is created by registering kanji or kanji-mixed sentences for words such as compound words and idioms in correspondence with this headword.For example, in the example above, the headword is changed to ``nihon'' to correspond to this headword. By registering ``Japanese Economy'', you can simply enter ``Nihon'' in kana and convert it to ``Japanese Economy'' at once.

By using such a user dictionary memory, it is possible to have a dictionary in which words such as compound words and idioms that are relatively often used by the user are registered, and this user dictionary can be used for kana-kanji 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. 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 word or phrase that has the entered ``Nihon'' as a headword, that is, the word that is a candidate for conversion, is ``Japanese word processor u, t+Nihon Keizai n.'' , ttJapan Bank of Japan colors exist, and it was necessary to output these candidate words and phrases one after another. 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.

<Purpose> 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, the dictionary's creator information 2, such as the creator's name or the section name to which the creator belongs (general affairs, sales, etc.), is registered in the registered words, and the conversion process is performed. By occasionally searching the user dictionary memory from the input kana characters and the creator information, conversion into the target phrase can be performed efficiently.

<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) The corresponding kanji or kanji-mixed sentence (conversion sentence) from the input kana sentence.
Conversion key that instructs conversion to .

(2) Next candidate key that instructs reading of another converted sentence.

(3) User dictionary creation mode key to create a user dictionary.

(4) A switch SW for instructing whether or not to register creator information in the user dictionary and instructing whether or not to read converted sentences from the user dictionary based on the creator information.

etc.

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 pass line 9. The editing control unit 2 is μ-CP.
It is composed of U.

Reference numeral 3 denotes 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 programmed from the floppy disk device ("FD") 6 when the power of the apparatus is turned on.

Among the 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 l; (2) A kana buffer that stores converted sentences read from a fixed dictionary memory or user dictionary memory, and stores the data on a display device or a disk 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), and the like.

Dictionary creator (or user) to the creator information buffer
For example, the information can be written in advance into a system file on a floppy disk to be used, and when the system file (editing program) is loaded from the disk, the information can also be loaded and stored, or when creating a text. When using the device, code information is input and stored through the keyboard device 1.

Reference numeral 4 denotes a fixed dictionary memory composed of a mask ROM, which is a conversion dictionary known for general kana-kanji conversion.

Tip 9: The dictionary stores headwords in reading kana and converted sentences or grammatical information corresponding to these headwords in pairs. Therefore, when a kana sentence is supplied to the dictionary memory 4 from the editing control section 2, the reading control of the dictionary memory 4 searches the headword in the memory 4 and selects the headword corresponding to the supplied kana sentence. , the converted sentence of the selected headword is output.

Reference numeral 5 denotes a magnetic disk device built into the device, which is composed of a user dictionary area (user dictionary memory) 51 and a text area 52 for storing created sentences.

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

In the creator information area 51C, the user's code information (the kanji code of the user's name or the unique ID code) from the creator information buffer described above is combined with the headword and converted sentence for each dictionary entry. It will be remembered as a result.

To explain the relationship between the above-mentioned switch SW of the keyboard device 1 and the creator information, if the switch SW is in the OFF state at the time of registration in the user dictionary memory 51 (during dictionary creation), the information is registered in the creator information area 51C. and when the switch SW is ON, the DK is displayed instead of the creator information.
This is to instruct that the creator is not specified by registering the null, 1 code in the area 51C.

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.

(I) Creating a user dictionary (Flowchart i in Figure 4)
(Reference) First, when the power of the device is turned on and the system file disk board is loaded into the FD device 6, the FD device 6 is loaded.
An editing control program is introduced from the device 6 into the program area 31 of the RAM 3.

If the creator information is registered in advance on the disk board of the system file, the creator information will be stored in RAM3.
is introduced into the creator information buffer configured in the data area 32 of. This creator information may be input from the keyboard device 1.

Next, when the user dictionary creation mode key of the keyboard device 1 is operated to set the mode, the flow shown in FIG. 4 is thereafter controlled to be executed.

In creating a user dictionary, first, the headword of the user dictionary, a kana sentence, is inputted from the keyboard device 1. This kana sentence is introduced into the kana buffer configured in the data area 31 of the RAM 3. This input kana sentence is
It is displayed on the display device 7.

The input of this headword is completed (for example, giving a completion instruction)
Then, the data in the kana buffer is sent to the user dictionary memory 51 and stored at the new registered address in the headword area 51A.

That is, in the initial state when nothing is registered in the user dictionary memory 51, it is stored at the first address of the headword area 51A. In the example shown in FIG. 3, the entry word ``Nihon'' is entered in kana, and in the initial state, it is stored at the first address of the entry word area 51A.

Subsequently, 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 is still 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 written into the output buffer.

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

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 to perform the conversion operation several times, and one registered converted sentence is obtained by combining the converted sentences. In the example of FIG. 3, the registered conversion sentence shows "Japanese word processor j."

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 4". be remembered.

Subsequently, 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 in the creator information buffer is stored in the user dictionary memory 51. personal information area 51
C, it is stored as a pair with the converted sentence.

In the example in Figure 3, the creator information is a code that indicates "Tanaka" based on the creator, and "Tanaka" is the area 51C.
will be registered.

Furthermore, if the switch SW is in the ON state, the creator information area 51C is an instruction not to register the creator.
A null code is written in the corresponding position.

A user dictionary is created in this way, and in the example of the user dictionary memory shown in Figure 3, the creator Pa Suzuki has registered ``Japanese economy'' as the headword in ``Hon'', and the creator Pa Yamamoto ” is the entry word “Nihon” and “Japanese lol”
O ([1)
Conversion Process 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 in the text display area of the CRT display device 7. Then, a conversion instruction is given using a predetermined kana sentence or a conversion key input.

In response to this display, the data in the kana 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 searches for the headword corresponding to the kana sentence inputted through the user dictionary memory 51. And the dictionary memory 5
If there is no headword corresponding to No. 1, the search proceeds to the fixed dictionary memory 4.

In the search of the user dictionary memory 51, when a corresponding headword is detected, for example, in the above example, if you input kana as ``nihon'' in the user dictionary memory 510, this will be detected because the headword in the user dictionary memory 510 includes ``nihon''. There are many things.

That is, in searching the user dictionary memory 51 in FIG.
For the kana word ``nihon'', the entry word ``nihon'' at the head of the memory 51 is detected.

Here, if "Yamanaka" is held in the creator information buffer of the device and the second switch SW is turned off and a search instruction is given based on the creator information, then the creator information corresponding to the detected headword is Area 51C is n u 1.
It is determined whether it is one coat or not. In this example, area 5. IC
Since "Yamanaka" is registered in , the null code is not detected.

If the null 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, the buffer contains "Pa Tanaka", and the bt area 51C contains "Pa Tanaka", so the converted sentence 1
The Japanese word processor is read out to the output sofa and displayed on the CRT display device 7.

Therefore, in this case, if you enter "'nihon",
It will be converted into "Japanese word processor".

In fact, if you enter ``Nihon'' while ``Precious Wood'' is stored in the creator information buffer, it will be converted to ``Nihon Keizai.'' In this case, the headword of the first address is ``Nihon''.
Since the creator information of ``Yamanaka'' does not match with ``Meiki'' in the creator information buffer, the address with the ``honest'' in the next entry term is selected, and the creator information of this address is ``Meiki''. Based on the match detection of “°Japanese economy””
is read out.

Well, detecting the null code in advance is n
Conversion sentences with a null code cannot be read regardless of the creator information, so in the above example in Figure 3, the creator buffer is set to ``Yamanaka'' and the ``Kana human power'' is set to ``Japanese word processor''. The converted sentences ``'' and ``Bank of Japan'' are conversion candidates, but since they are detected from the first address, the converted sentences ``Pacific Japanese Word Processor'' are 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, unless the search is based on the creator information, the search will be performed by the Japanese language word browser ``'' and the ``Japan Keizai I'' for the ``Kana human power''.
I, TI Nippon Rokugyo'', and °゛Japan wp'' are conversion sentence candidates.

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.

Effect> 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. However, regarding a user dictionary that can be registered and created by the user at will, the entry word given by the first character, the converted word or converted sentence given by the corresponding second character, and this converted word Alternatively, the user dictionary is configured to store the registered creator of the converted sentence or the creator information indicating the person to whom it belongs, etc., as a pair, and the image information of the headword and the creator information is stored in the user dictionary when the conversion process is performed by the user dictionary. By performing a search, the conversion process to the target word or sentence can be performed at high speed, and the processing using the user dictionary can be performed efficiently. )
