Abstract

PURPOSE:To perform efficient conversion processing by performing the retrieving operation of the 2nd dictionary selectively on the basis of both an index word and generating operator information and only the index word. CONSTITUTION:When a user dictionary 51 is generated, ''nihon'' in KANA (Japanese syllabary) as the index word is inputted 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 from the device 1, the conversion sentence ''Japanese word processor'' is obtained. In this case, the retrieval is performed on the basis of only the index word when the switch SW is on.

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 created arbitrarily.

<Prior art> There are various methods for kana-kanji conversion or romaji-kanji conversion devices that are generally used such as Japanese word processors, but one method is to input kana sentences by dividing them into clauses or words, and converting the kana sentences into It is supplied to a conversion dictionary and converted into kanji or kanji-converted sentences.

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, enter ``hon''' in 1, convert, and then ``keizai''.
I had to type it in 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.

Therefore, a device has been proposed that includes 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. In the example, by setting the headword as ``Nihon'' and registering ``1 Nihon Keizai'' corresponding to this headword, it is possible to convert ``11 Nihon Keizai'' by simply inputting ``Nihon'' in kana. be.

By using such a user dictionary memory, it is possible to have a dictionary of the user's preference, that is, a dictionary in which compound words, phrases, etc. that are relatively often used by the user are registered, and this user dictionary can be used to process kana-kanji conversion. can be done quickly.

However, this user dictionary memory allows users to freely register words and phrases to create their own dictionaries; for example, if multiple people use the device, they will need to create their own user dictionaries individually. 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 9 as ``hon''.
Further, user B may register the headword as ``1 nihon'' and register it as ``Japan Economy,'' and furthermore, user C may register the headword as ``nihon'' and register it as ``Bank of Japan.''

In this case, when user C inputs ``Nihon'' in this user dictionary memory, the words and phrases that have the entered ``Nihon'' as a headword and are candidates for conversion are ``Japanese Word Processor'' and 6 Japanese. ``Keizai II, 11 Bank of Japan'', and it was necessary to output these candidate words and phrases in sequence. In other words, the number of candidates for conversion increases and the time required for conversion processing becomes longer.

In other words, the user dictionary is currently not being 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. 4 In particular, when creating a user dictionary, the creator information of the dictionary is registered together with the registered words, such as the creator group or the section name to which the creator belongs (general affairs, sales, etc.), and during the conversion process, By searching the user dictionary memory based on the input kana characters and the creator information, it is possible to efficiently convert the words into 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) A conversion key that instructs the conversion of input kana text to the corresponding kanji or kanji-mixed text (conversion text).

(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, that key
For example, it is encoded by the control section and supplied to the editing control section 2 via the pass line 9. The editing control unit 2 is a p-CPU.
It consists of:

3 is R'AM, 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 on a floppy disk device (FD) when the device is powered on.
6 to 4.

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 the fixed dictionary memory or user dictionary memory, and stores the stored data in the display device or the device. (3) a creator information buffer 1 for storing dictionary creator (or user) information (in this example, user's personal code information);

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 for personal use, 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. Keyboard device 1 when using the device
It is used to input and store code information.

Reference numeral 4 denotes a fixed dictionary memory composed of a mask ROM '7', which 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, 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 is performed by searching the headword in the memory 4 to find the headword corresponding to the supplied kana sentence. is selected, and 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, each time the dictionary is registered, 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. It will be remembered without.

Here, to explain the relationship between the 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 creator information is stored in the creator information area 51C. When the switch SW is ON, a null code is registered in the area 51C instead of the creator information to instruct that the creator is not specified.

On the other hand, when the switch SW is in the OFF state during conversion processing by the user dictionary memo 1J51, an instruction is given 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 search.

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

Next, a series of operations of the device shown in FIG. 1 will be explained together with the operation flow shown in FIGS. 4 and 5. 1 (I) Creating a user dictionary (see the flowchart in FIG. 4) First, turn on the power of the device. When the FD device 6 is loaded with a system file disk, the FD
An editing control program is introduced from the device 6 into the program area 31 of the RAM 3.

In addition, if the creator information is registered in advance on the disk board of the system file, the creator information is stored in the 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, one kana sentence is inputted from the keyboard device 1 as a headword for the user dictionary.

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 CRT display device 7.

Enter or complete this headword (for example, give 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 of the 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 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 51.

Next, if you enter the reading kana of the conversion sentence you want to register again from the keyboard device 1, this kana sentence will be registered in Kanabaran 7.
and displayed on the CRT display device 7. 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 1.

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

The converted sentences to be registered are generally made up of special words such as compound words and phrases, and therefore, the conversion operation is performed several times using the fixed dictionary memory 4, and a single 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 j". be remembered.

Since this is an instruction to register the creator information, the data in the creator information buffer is stored in the creator information area 51C of the user dictionary memory 51 as a pair with the converted sentence. It will be remembered without.

In the example in Figure 3, the creator information is a code that indicates the country of the creator's name, and that country is the area 51C.
K will be registered.

Furthermore, if the switch S'W75i is in the ON state, this is an instruction not to register the creator, so a null code is written in the corresponding position of the creator information area 51'C.

In this way, a user dictionary is created, and in the example of the user dictionary memory shown in Figure 3, the creator Suzu Meiki has registered ``Japan Economy'' as the heading ``Nihon'', and In addition, the creator "Sansui" registered "Japanese wp" as the headword 1, and the creator was not registered (
Turn on the above switch SW), and set the heading word to II.
' L l f 110-1-m 舛h L Qini) and - Small Ze-21.

(2) Conversion processing using the user dictionary (see flowchart in FIG. 4) When a kana sentence to be converted (by keyboard device 1) is input, 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 conversion key into which a predetermined kana sentence is input.

In response to this instruction, the data in the kana buffer is supplied to the user dictionary memory 51. That is, the user dictionary memory 51 is provided ahead of the fixed dictionary memory 4, and searches for the headword corresponding to the kana sentence input from the user dictionary memory 51. And the dictionary memo I
If there is no headword corresponding to J51, the fixed dictionary memory 4
Shift to search.

In the search for the user dictionary memo IJ 51, if a corresponding headword is detected, for example, in the above example, 11.
When inputting kana, this will be detected because the headword in the user dictionary memory 51 includes ゝnihon.

That is, in searching the user dictionary memory 51 in FIG.
For the kana human power ``nihon'', only n words are detected in the headword at the beginning of the memory 51.

Here, if "Yamanaka" is held in the creator information buffer of the device, and if the switch SW is turned off and there is a search instruction based on the creator information, then the creator corresponding to the detected headword is Information area 51C is null
It is determined whether it is a code or not. In this example, area 51CK
Because Ta Yamanaka is registered, 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 1 contains 1 Tanaka Pa, and the area 51C is still "N Yamanaka", so the conversion sentence "
"Japanese Food Pro Sensor" is read out to the output sofa and displayed on the CRT display device 7.

Therefore, in this case, if you input "Nihon", it will be converted to "Pacific Japanese Word Processor".

Well, if you enter "Nihon" with "Precious Wood" stored in the creator information buffer, it will be converted to "Nihon Keizai". In this case, the creator information for the headword 1 "Nihon" at the first address will be " Since it is "daytime" and does not match the "precious wood" in the creator information buffer, the address with the next headword "hon" is selected, and based on the detection of a match with the creator information "precious wood" for this address. Then, the ``Japanese Economy'' is read out.

Note that detecting the null code in advance is as follows:
This is because a conversion statement with a null code is read regardless of the creator information. Therefore, in the above example in Figure 3, the creator buffer is set to "Japanese" and "Kana human power η nihon" is written as "Japanese". The conversion sentences ``Word Processor'' and ``Bank of Japan'' are the conversion candidates, but since they are detected from the first address, the conversion sentence ``1 Japanese Word Processor'' is read first.And when this is not the desired conversion sentence, , when the following instruction key is operated, a conversion sentence such as ``Pacific 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, ``Japanese word processor rr, , t+Nihon Keizai II, 11 Bank of Japan'' will be returned for ``Kana Jinriki ``Nihon''.

``Japanese w p'' is a conversion sentence candidate. - In the above embodiment, the Kana-Kanji conversion has been described, but the conversion can also be performed in the same way for Romaji-Kanji conversion or from Kana or Romaji to English.

Effect> As described above, in the present invention, the first character given in Kanaji or Romaji is converted into the second character such as Kanji or Kanji Saijibun corresponding to the @1 character. a character conversion device and a headword given by the first character;
A first dictionary (fixed dictionary) in which a predetermined number of converted words or converted sentences given by corresponding second characters are registered in advance, and a user (user) can register and create them arbitrarily. In the device, the headword given by the first character, a converted word or a converted sentence given by the corresponding second character, and this converted word or The above-mentioned second dictionary stores the registered creation of the converted sentence, the creator information indicating the author, the person to whom it belongs, etc. in sequence, and the above-mentioned creator information' input from the outside during the character conversion process. buffer means for temporarily storing, in response to a character conversion instruction, both the headword of the second dictionary and the corresponding creator information from the information of the input first character and the creator information given from the buffer; It is fully equipped with a control means for searching and determining a converted word or a converted sentence, and an instruction means for giving an instruction, and the operation of the instruction means causes the search operation of the second dictionary to be performed based on both the entry word and the creator information. It is possible to select between a search and a search using a headword, so by searching the user dictionary using image information of a headword and creator information, conversion to the target word or sentence can be performed. It has the characteristics that it can be performed at high speed, and that it is also possible to search only from headwords if necessary, so that the user dictionary can be used efficiently.
