Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention is a method for inputting a first character such as a kana and selecting a desired character from a second character group such as a homophone kanji group corresponding to the kana. The present invention relates to a character conversion device that selects a second character and converts the first character into the second character.

``Prior Art'' For example, in a conversion device that converts a word input as a first character such as a kana into a second character such as a kanji corresponding to the kana, how can a desired word be converted from a homophone kanji? The problem is which one to choose.

In this way, one of the conversion devices that outputs a desired one of the homophone kanji is to first display all the homonym kanji corresponding to the word input in kana on the display, and then the operator can By selecting and instructing the desired kanji from the homophone kanji group displayed above,
There are known devices that output desired kanji.

However, if such a conversion device is used, all of the multiple homophone kanji are displayed on the display, and the operator must search for the desired one among them, which requires time for the operator to search, and also , operator fatigue is also significant.

Furthermore, since there may be an extremely large number of kanji characters that correspond to a word entered in kana, a large number of selection keys are prepared so that the operator can select a desired one from the large number of words on the display. It was something I had to keep.

Problems to be Solved by the Invention The present invention provides a device that allows the reading of a kanji to be input and the desired kanji to be input more easily when inputting kanji information.

Means for Solving the Problems The present invention provides an input means for inputting the reading of a kanji, a storage means for storing kanji information corresponding to the kanji reading and selection information of the frequency of use of the kanji information, a setting means for setting a threshold value regarding selection information for searching for kanji information, and a reading of the kanji from the storage means based on the reading of the kanji from the input means and the threshold information from the setting means; and a search means for searching for the corresponding Kanji information having selection information equal to or greater than the threshold value.

That is, if a predetermined number is output as a unit, the range of search by the operator is limited, making the search easier.

In addition, if a predetermined number of characters are to be output in this way, for example, a predetermined number of indicating means for indicating whether or not the output character is the desired character may be provided, so that the configuration of the selection mechanism can be changed. can also be simplified.

Furthermore, if the output order is arranged in order of frequency of use, the chances of selecting characters that are displayed earlier will naturally increase, and the time required to select a desired character will also be shortened. be.

In addition, in the detailed description of the present invention described below, the predetermined number n is assumed to be 1.

In addition, the first character referred to in the present invention includes the Roman alphabet that is a combination of hiragana, katakana, and alpha alphabet characters, as well as languages of other countries such as BOOK, and the second character refers to the above-mentioned kana and Roman characters. Homophone characters such as kanji corresponding to , and the above-mentioned BOOK
It also includes synonymous characters such as ``book'', ``book'', and ``book'', which correspond to ``book''.

"Embodiment" The present invention will be described below in detail with reference to the drawings.

Figure 1 shows the external appearance of a character conversion device according to the present invention. is input from the keyboard and converted into the desired kanji.

With the kana-kanji conversion device, all you have to do is input kana and instruct it to be converted into kanji.
Naturally, multiple kanji that are homophones are selected for one input, but in this embodiment, the frequency of use of the kanji is used as a foothold to select a desired kanji from among the kanji that are homonyms. It is selected as

In the embodiment, "total word usage frequency", "homonym usage frequency", and "field" are used as the types of usage frequency, so before going into the specific explanation of the character conversion device, such "usage frequency" will be explained. Let me explain.

Total word usage frequency refers to the number of times a word appears in the total words of a certain sentence, and is divided into standard total word usage frequency and input total word usage frequency.

This standard total word usage frequency refers to the number of times each word appears relative to the total number of words surveyed in a word frequency survey. For example, if all newspaper pages are examined over a certain year, Something like indicating how many times a certain word appears.

Therefore, the standard total word usage frequency can be given by the following formula.

Frequency of standard term usage
= Number of occurrences of each word / Total number of words in the survey The input total word usage frequency indicates how many times a certain word was input into the device among the total words input into the character conversion device. The input total word usage frequency is given by the following formula.

Total input word usage frequency = Number of inputs for each word/total number of input words.

Homophone frequency refers to the number of times each word appears in the total number of homophones (for example, 臜, 端, chopsticks, bridge) in a sentence, and is divided into standard homophone frequency and input homophone frequency. .

This standard homophone usage frequency refers to the ratio of the number of times a word appears to the number of times the homophone of a certain word appears in a word frequency survey. Find out how many (m) times the kanji corresponding to "chopstick" appears, and if chopsticks appears (n) times, then n/m is the standard homophone usage frequency of "chopsticks".

The input homophone usage frequency indicates how many times the homophone of a certain word is input into the character conversion device, and how many times the certain word occupies among the number of inputs. For example, if the kanji character corresponding to ``hashi'' is inputted M times, and N times of those kanji characters are ``chopsticks'', N/M corresponds to the input homophone usage frequency of ``chopsticks''.

Note that the homophones used in the above explanation refer to words that have the same sound but have different letters; for example,
It refers to ``winter season'', ``winter season'', ``speculation'', ``pottery'', etc.

Also, in this embodiment, the idea of fields is used, but this is to take advantage of the fact that the frequency of use of language differs depending on the field in which it is used, such as politics, economy, society, sports, etc. home,
Examples of fields include science, fisheries, mining, construction, food, textiles, pulp and paper, chemistry, petroleum, rubber, ceramics, steel, metals, machinery, electricity, transportation, precision, commerce, medicine, music, etc. . In addition, all fields can be treated as one field, and furthermore, since there are characteristics in the language used by individuals who use input conversion devices, it is possible to classify such fields by field. You can add an individual as one. However, when such an individual is added to the field, it is difficult to investigate the frequency of use of standard total words and standard homophones by the individual, so in such cases, the frequency of use of input total words and input homophones is the main focus. It will be.

Now, to explain the present invention according to the drawings, numeral 11 in FIG. 1 is a housing of the character conversion device according to the present invention, and the front part of this housing 11 is used for inputting information. Operation panel 1 for performing

Any value between 10 ^{and -0} can be set.

Threshold setting dials 21, 22 as described above
If there are multiple homophones for a certain character input using the key 13, the dial 2
By selecting only words having a frequency equal to or higher than the threshold value set in 1 or 22, a function such as selecting one word from a plurality of homophones is performed.

Reference numeral 23 indicates a key for forcibly changing the frequency of use of input total words and input homophones in a file to be described later in which the frequency of use of input homophones is stored.

To change the input word usage frequency, select the relevant word in the file above and press key 23-1.
By pressing , and inputting the desired frequency of use using the numerical keys 13-1, the frequency of use of the word in the selected field can be changed. Similarly, when changing the input homophone usage frequency,
With the relevant word selected in the file, press key 23.
The usage frequency of the word concerned can be changed by pressing -2 and inputting the usage frequency desired to be set using the numeric key 13-1.

24 indicates that only when a certain number of words or more are input into the character conversion device, a specific word is selected from a group of synonyms of a certain sound using the input usage frequency such as input total word usage frequency and input homophone usage frequency. This dial is used to set the threshold value h for selecting , and can be arbitrarily set from 10 ⁰ to 10 ³ .

Reference numeral 25 indicates a learning switch, which is a switch for selecting whether or not the character conversion device should learn the frequency of use of words input to the character conversion device.

Note that learning here refers to updating the content of usage frequency according to an increase in input by sequentially counting input words, such as input total word usage frequency and input homophone usage frequency.

Reference numeral 26 indicates a switch for displaying the number of occurrences of the words stored in the file (which can be considered equivalent to the frequency of use) on the CRT display 27. For example, when selecting a field, key 20
After selecting "Politics" and pressing the key 19-1, inputting "Touki" using the character key 13, then pressing the key 19-2 and then pressing the key 26, for example, as shown in FIG. , the corresponding portion of the file described later is displayed, and the standard number of occurrences (marked as standard), number of inputs (marked as input in the figure), and total number of words are displayed on the display 27. be done.

In addition, the display device 27 converts characters input using keys into kana or kanji characters and displays them sequentially as shown in FIG. 15, for example.

A printer such as a thermal printer is housed in the housing 11, and by pressing a key 28-1 or by commands from a control circuit to be described later, characters displayed on the display 27 are printed on a recording paper 29. This can be recorded above.

Reference numeral 30 indicates a mode changeover switch, which is a key for instructing which of the following three modes selects a desired word from homophones.

That is, (a) standard total word usage frequency or standard homophone usage frequency (hereinafter both will be collectively referred to as standard usage frequency) is used. (b) Use the input total word usage frequency or the input homophone usage frequency (hereinafter both will be collectively referred to as input usage frequency). (c) Threshold setting dial 24
If the number of words input is equal to or higher than the threshold value h set in , the input usage frequency is used, and if the number of input words does not reach the threshold value h, the standard usage frequency is used. The input usage frequency and the standard usage frequency are automatically switched by comparing the threshold value h with the number of words obtained through learning in the past. Hereinafter, these modes will be referred to as a mode, b mode, and c mode, respectively.

28-2 indicates that when searching for a desired word from multiple homophones, if there are multiple homophones that have a usage frequency greater than the threshold value g set with the dial 22, one word can be searched in any mode. This is the key to instruct the selection, and the key 28-2 is
By leaving it ON, multiple words with usage frequency greater than the threshold value can be displayed simultaneously on the display 27.
By setting the key 28-2 to OFF, the word with the highest usage frequency among the words with a usage frequency greater than the threshold value is displayed on the display 2.
7.

As described above, when the key 28-2 is turned ON and multiple words are displayed on the display 27 at the same time, the desired word is indicated on the display 27 using the cursor described above or a light pen (not shown), etc. According to
The word can be selected.

In addition, when the word with the highest frequency of use is displayed with the key 28-2 turned OFF, if the displayed word is the desired word, the word can be selected by pressing the OK key 10, and the displayed word can be selected. When the word is not the desired word, by pressing the shift key 9, the next most frequently used word after the word that has been displayed so far is displayed on the display 27. In short, by pressing the shift key 9, words that are used less frequently can be sequentially displayed, so that when a desired word is displayed, pressing the OK key 10 selects the word.

Incidentally, lamps 7 and 8 are provided on the side of the display 27, and this lamp 7 is connected to the key 28-2.
This is a lamp that notifies the operator that when there are multiple words that are equal to or higher than the threshold value when the word is turned on, the operator should check whether the word displayed on the display 27 is acceptable. Reference numeral 8 denotes a lamp that indicates that there is no corresponding kanji in the file, which will be described later, even though kanji conversion has been instructed.

3, to 6 (generally referred to as 2) are cursor keys, and by driving each key, the cursor on the display can be moved in the direction of the arrow displayed on the key. It is.

FIG. 4 is a block diagram showing the control circuit of the character conversion device shown in FIG.
Reference numeral 31 indicates a ROM that stores various control programs as described below, and the contents of this ROM are decoded and executed by a processing section 32. Reference numeral 33 denotes a RAM for temporarily storing information, which temporarily stores information sent from the processing section 32 or information sent from the storage device 34, and sends the stored information to the processing section 33. It is something. RAM3
3 contains local memories A to D, registers a to
g is provided.

Reference numeral 34 indicates a storage device such as a magnetic disk, and in this storage device, files such as a kana-kanji conversion dictionary and usage frequency data are stored in the form shown in FIG. be.

That is, in the heading area 36, characters to be converted into Kanji are arranged in alphabetical order, as in, for example, a normal Japanese dictionary.

However, in the actual storage device, it is of course arranged as an 8-bit code, so for example "Touki" is (01000100) (00110011).
(00110111).

Following this area is a homophone number area 37, and this area 37 stores a number indicating how many homophones belong to the header area 36.

38 is the kanji area, and the heading area 36
Homophones belonging to ``are stored in the form of kanji codes.

39 is an area that stores the data that is the basis for calculating the usage frequency of each word in a certain field A (for example, politics), and area 39-1 is the area that stores the data that is the basis for calculating the usage frequency of each word in a certain field A (for example, politics). This area stores the standard number of occurrences of each word in 39-2.
is an area in which the number of inputs of each word in the political field is stored in order to calculate the input total word usage frequency.

Similarly, the standard number of occurrences of each word in field B (e.g. economics) is stored in area 40-1, the number of inputs is stored in area 40-2, and so on, across all fields. .

Furthermore, the area 41 is an area that stores data that is the basis for calculating the frequency of use in all fields without limiting the field, 41-1 stores the standard number of appearances, and 40-2 stores the number of inputs. It is something that

Note that an address area 42 is provided between the areas 37 and 38 to store an address corresponding to each word.

Since the length of each of the areas 36 to 42 is determined in advance to be a certain length, each area at a certain address can be separately identified.

Note that the total number of words for each field and the total number of words for all fields are stored at address 0 of this file.

That is, the area 43 stores the standard total number of words in field A, which is the sum of all the standard appearances of each word in field A, and the area 44 stores the standard total number of words in field B, which is the sum of all the standard appearances of each word in field A. The standard total number of words in all fields is stored, and the area 45 stores the standard total number of words in all fields, which is the sum of the standard number of appearances of each word in all fields.

Also, the area 46 stores the total number of input words in field A, which is the sum of all the input times of each word in field A, the area 47 similarly stores the total number of input words in field B, and the area 48 similarly stores the total number of input words in field A. The total number of input words in all fields is stored.

When the learning switch 25 of the character conversion device is set to ON, the total number of input words and the number of inputs for the field selected by the field selection key 21 and the input number for the area 48 are calculated every time a new word is selected. The total number of words and the number of inputs of the selected word are incremented.

In FIGS. 1 and 2, keys for selecting individuals are provided as field selection keys, but in FIG. 5, the areas corresponding to such individuals are the areas 39-2 and 4.
It is configured in the same way as 0-2.

In addition, in the above file, the area indicated by 36-1 corresponds to the kana-kanji conversion dictionary, and 36-1 corresponds to the kana-kanji conversion dictionary.
The area indicated by -2 corresponds to the frequency of use file.

Now, returning to the explanation of FIG. 4 again, 50 is a thermal printer, and 51 is for displaying kana, codes, exchanged kanji, etc. input by the display controller section on CRT 52.

As shown in detail in FIG. 6, the CRT refresh memory 53 and the CRT output control section 5
It is composed of 4. 52 is a CRT which is a display shown in FIG.

The refresh memory 53-1 is a memory for the entire surface of the CRT 52. This refresh memory 53
The pattern is output by writing the pattern from the character pattern generator to -1.

The CRT output control section 54 is activated by a command from the processing section 32 and performs control to display the contents of the refresh memory 53 on the CRT 52. Control is performed using known methods, such as
Consists of VIDEO signal generation IC, Hitachi HD46505 or Intel 8275.

Reference numeral 53 denotes a character pattern generator, which generates a pattern signal corresponding to the code signal to the display controller by applying a character code signal input from the character key 13 or a kanji code signal derived from the storage device 34. The information is sent to the section 51.

The processing section 32 and other devices are connected by bus lines 54-1 to 54-4, and these bus lines include an address bus, a control bus, and a data bus.

Next, the operation of the control circuit shown in FIG. 4 will be explained with reference to FIGS. 7 to 15.

FIG. 7 is a flowchart for determining whether or not it can be uniquely displayed. In step 60, a character or symbol signal is input from the keyboard 13.
It is determined in step 61 whether the signal derived in this way is a signal that has been instructed to be converted into a kanji, and if the signal is a signal that has been instructed to be converted into a kanji. , step 62
If the conversion is not to be performed, the process proceeds to step 63.

To make the determination in step 61 in this way, key 1
This can be easily determined by detecting whether 9-1 or 19-2 has been pressed. For example, if you want to output "from that speculation," press the So, No, keys 13, then press the keys 19-1, then press the To, U, Ki, and then press the keys 19-2. Since key 19-1 is pressed, key 19-1 is pressed and then key 19-1 is pressed.
- The signal input while 2 is pressed is sent to step 62.
The next step is to proceed to

As mentioned above, if a signal has not been instructed to be converted into a kanji character, the process proceeds to step 63, but this step 63 is a display step that displays a pattern corresponding to the sent signal. A signal is sent to the character pattern generator 53 and the corresponding character pattern is sent to the refresh memory 51.
and store this stored pattern on the CRT52.
This is the step to display. It should be noted that in the following explanation, there will be other display steps, but these display steps are similar to those described above.

As mentioned above, a signal instructing conversion to kanji is sent to step 62;
is the order in which the signals were sent,
The data is sequentially stored in the local memory A that forms part of the RAM 33.

Having completed step 62 in this manner,
In step 64, it is determined whether the input of the signal to be converted into kanji has been completed or not. If the next input has not been completed, the process returns to step 60 and waits until the input is completed. When the input is completed, the next step is started. 6
Proceed to step 5. Specifically, this step 64 only needs to detect that the key 19-2 has been pressed.

In step 65, the content of the local memory A is compared with the heading 36 in the storage device (file) 34 to find a match.

For example, (key 19-1) (g), (c), (k) (key 1
When the keys are pressed in the order of 9-2), a word is stored in the local memory A, so a word corresponding to this word is searched. Such a search can be performed by comparing the headings in the local memory A and the storage device 34 in the comparator 32-2 of the processing section 32. Then, in step 66, it is determined whether or not there is a corresponding word, and if there is no corresponding word, step 66 is executed to display the contents of the local memory A as they are (in other words, without converting them into kanji). 67, the contents of local memory A are selected, and the display step 63
Proceed to.

That is, if there is no corresponding kanji in the file, the input characters are displayed as they are in kana.

If there is no corresponding kanji in this way, the lamp 8 is driven to display "No matching word" in step 68 in order to notify the operator of this fact.

If it is determined in step 66 that the relevant word exists, then in step 69 the data of the specified field and all fields of the relevant word in the file and the total number of words are stored in the local memory B constituting the RAM 33.

For example, if "Toki" is input as described above and the field selection key is activated to select "Politics", then in FIG. ，
and data 43, 46, 45, and 48 are stored in local memory B.

After a portion of the file has been transferred into the local memory B in this manner, it is then determined in step 70 whether there is one homophone. Specifically, it may be determined whether the number of homophones stored in area 37 of local memory B is 1 or not.

If the number of homophones is 1, step 71
The kanji code is selected at , and this kanji code is sent to the display step 63. Note that a learning subroutine step 72 is provided between the steps 71 and 63, and this subroutine consists of steps as shown in FIG.
This is a step to enrich your file.

That is, the code selected in step 73 is stored in RAM.
Store it in the local memory E of 33 (leave it as it is in the local memory B as well) Step 74
It is determined whether the learning switch 25 is turned on or not, and if it is not turned on, the process proceeds to step 78.
Exit this subroutine directly via
If it is ON, proceed to the next step 75.

This step 75 increments the number of inputs of the selected word in local memory B. For example, if a word corresponding to "speculation" is selected in the political field as in the above example, local memory B
The number of times of area 39-2 (15) and the number of times of area 41-2 (203) at address n+4 are increased by 1, and these increased values are stored again in areas 39-2 and 41-2 at address n+4. It is something.

When this step is completed, the program proceeds to step 76, in which the contents of areas 46 and 48 at address 0 in local memory B are incremented by 1, and this increased value is again stored in areas 46 and 4 at address 0.
Store in 8.

After the contents of local memory B have been incremented in this way, in step 77, the data of the number of inputs in local memory B (area 39
-2, 41-2, 46, 48) are stored in the corresponding area of the storage device 34.

This causes the data in the storage device 34 to become “speculative”.
is input once, it means that it has been changed to the learned value.

Once the learning results have been stored in the file in this way, the process moves to the next step 78, where the selected Kanji code stored in the local memory E is selected.

Now, returning to FIG. 7 again, if it is determined in step 70 that there are multiple homophones as described above, the desired one word must be selected from the multiple homophones in some way. ,
In this example, standard usage frequency (general term for standard usage frequency and standard homophone usage frequency)
Alternatively, it is determined whether to select a desired word using the input usage frequency (which collectively refers to the input total sound usage frequency and the input homophone usage frequency).

Therefore, after completing step 70, the program proceeds to the usage frequency calculation program shown in FIG. 9, which calculates the usage frequency of each word and stores the usage frequency in the local memory B as shown in FIG. 10.

That is, in step 89, the sum of the standard number of occurrences of the specified field of the file stored in local memory B is calculated and the sum is stored in local memory C. That is, add the number of times in area 39-1 belonging to "Toki" in Figure 10 (153 + 125 + 115
+64) The result P(457) is stored in the local memory C.

Once this step is completed, the next step is step 9.
0, the sum of the number of inputs for the specified field of the file stored in local memory B is calculated, and the sum is stored in local memory D.

That is, the number of times in the area 39-2 belonging to "Touki" in FIG. 10 is added (9+10+15+6) and the result Q(40) is stored in the local memory D.

Once PQ has been stored in the local memory CD in this manner, the process proceeds to the next step 91, where the frequency of use of each homophone is calculated and the answer is stored in the area 80 of the local memory B.

That is, the standard total number of words is area 4 of local memory B.
3, so the number 2.5 from area 43
×107 is read out and sent to the calculation unit 32-1 forming a part of the processing unit 32, while the numerical value 153 corresponding to address n+2 in the area 39-1 is read out and sent to the calculation unit 32-1, and the calculation In section 32-1, 153/2.5×107 is executed and the calculation result is
By storing 6.13 × 10 ^-6 in the area corresponding to address n+2 in area 80 of local memory B, the frequency of use of the standard general term "winter" is calculated, and in the same manner, the usage frequency of "winter", "speculation", and "pottery" is calculated. The frequency of use of standard general words is determined and stored in area 80.

Once the standard total word usage frequency of all words in the designated field in the local memory B has been determined in this manner, the process proceeds to step 92 and the standard homophone usage frequency of each word is determined.

That is, the addition result P from the local memory C
is read out and sent to the calculation unit 32-1, and then the standard number of occurrences 153 of “winter season” is sent to the calculation unit 32-1, 153/P is executed in the calculation unit 32-1, and the calculation result 0.335 is sent to the local In the area 81 of memory B, the standard homophone usage frequency of "winter season" is determined by storing it in the area corresponding to address n+2, and then the standard homophone usage frequency of "winter season", "speculation", and "pottery" is determined in the same manner as in the area 81. It is stored in .

Once the standard homophone frequency of all words in the specified field in register B has been determined in this way, the process proceeds to step 93, where the input total word frequency of each word is determined and 82. The method for determining the frequency of use of such input total words is similar to step 91, so a detailed explanation will be omitted.

Once the input total word usage frequency has been determined in this manner, the process proceeds to the next step 94, where the input homophone usage frequency is determined and stored in area 83 in local memory B.
The method of determining the frequency of use of the input homophone is similar to step 92, so a detailed explanation will be omitted.

By executing steps 89 to 94 above, all usage frequencies in the political field (designated field) are calculated, and the results are stored in the B register.

After creating such a usage frequency file in the local memory B, the process enters the step shown in FIG. 11, in which it is determined whether to use the standard usage frequency or the input usage frequency.

Step 105 determines whether or not the step 30 is in the a mode, that is, whether or not a command has been given to select a desired word from a plurality of homophones using the standard frequency of use. If it is, the process moves to step 111 and the processing section
Set the flip-flop P included in 0 to 0. This flip-flop P is controlled so that when its content is 0, the standard usage frequency in the local memory B is used, and when P is 1, the input usage frequency is used.

If you are not in A mode, proceed to the next step 1.
The process advances to step 06, and it is determined whether the addition result Q stored in the local memory D in step 106 is greater than 0, that is, whether or not this character conversion device has already learned. If Q > O here, even if the switch 30 is in a mode other than A mode, there is no data stored in the file that should be used as the basis for judgment, so the standard frequency of use is forced. The process advances to step 111 in order to set the flip-flop P to 0 in order to set the mode in which .

On the other hand, when Q>O, the next step 107
Then, it is determined whether the switch 30 is in the b mode or not.

If you are not in B mode, proceed to step 1.
08, it is determined whether the switch 30 is in the c mode or not, and if it is not in the c mode, the process advances to step 111.

On the other hand, when it is determined in step 107 that the switch 30 is in the b mode, the process proceeds to the next step 109, and the threshold value h set with the dial 24 is compared with the value Q in the local memory D. However, if Q≧h, the flip-flop P is set to 1 in step 110 to use the input usage frequency.
If Q<h, the process proceeds to step 111 to use the standard usage frequency.

Also, in step 108, the switch 3
If 0 is in c mode, step 11
It advances to 0.

By completing the above steps, it is determined whether to use the input frequency of use or the standard frequency of use, and this is stored in the flip-flop P.

That is, when the flip-flop P is 0, in the file as shown in FIG.
Using standard homophone usage frequency, if P is 1, area 8
This method uses the input total word usage frequency and the input homophone usage frequency of 2.83.

Step 110 or 11 in FIG.
After completing Step 1, the next step is Step 115 in Figure 12.
However, in this step 115,
This is to determine whether or not there is a word in the file in the local memory B with a total word usage frequency that is equal to or higher than a threshold value g set using the dial 22.

As described above, when P=0, the standard total word usage frequency is compared with the threshold g, and when P=1, the input total word usage frequency is used.

As a result, if there is a word that is equal to or greater than the threshold value g, the process advances to the next step 116, and if there is no word, the process enters the flowchart shown in FIG. 13.

In step 116, it is determined whether or not there is one word with a total word usage frequency greater than or equal to the threshold value g. If it is one word, the kanji code of the word is selected in step 117, and the learning subroutine step 125 is displayed. Proceeding to step 127, the selected word is
5 Display as shown in FIG. 172.

On the other hand, if it is not one word, proceed to step 118 to determine whether or not the key 28-2 is turned on. If it is turned on, proceed to the next step 120.
Then, the process proceeds to a display step 127 via a frequency-of-use subroutine 120, which will be described later, which selects all words whose frequency of use exceeds the threshold value g and sends them out in descending order of frequency of use. For example, if there are two words that are equal to or greater than the threshold value g, the display will be as shown in FIG. 15, 173.

As for the words selected to be displayed simultaneously in step 120 in this way, a desired one may be selected on the spot from among the plurality of words displayed.
Another method is to input the next character using the character key 13, and after completing one page of text on the display, select the desired one from among the multiple words. It's good.

In step 118, the key 28-2 is activated.
If it is determined that the word is OFF, the process proceeds to the next step 119, and the word having the maximum total word usage frequency is selected and displayed. Selecting a frequently used item in this way can be executed in almost the same steps as the usage frequency subroutine described later, so a detailed explanation will be omitted here. Then, in the next step 121, the lamp 7 is turned on in order to inquire of the operator whether the displayed word is the desired one.
Once the lamp 7 is turned on, the process advances to the next step 122, where it is determined whether the operator has pressed the OK key 10 or not. If the OK key 10 has been pressed, a learning subroutine 125 is entered, and if it has not been pressed, a step 124 is entered to determine whether or not the shift key 9 has been pressed.

If the shift key 9 is not pressed, the process waits, and if it is pressed, the process advances to the next step 126. This step 126 is for converting the total word usage frequency of the words displayed so far to 0, and after the completion of this step 126, the process returns to step 119 again.

In other words, in step 126, the usage frequency of the word with the highest usage frequency, which has been displayed until now, is converted to 0, so in step 119, the word with the second usage frequency is selected and displayed. It is something that will be done.

In this way, by pressing the shift key 9, words with low frequency of use are sequentially displayed, and if the OK key is pressed when the desired word is displayed, the process proceeds to the learning subroutine 125.

As mentioned above, when there is a word whose total word usage frequency is higher than the threshold value g, the desired word can be selected in some way according to the flowchart shown in Figure 12. Frequency is threshold g
If there is no word larger than , the process proceeds to the step shown in FIG.

The step indicated by 130 is a step for determining whether the frequency of use of the same sound is greater than the threshold value f set by the dial 21, but as described above, if P=0
Of course, when P=1, the standard homophone usage frequency is compared with the threshold f, and when P=1, the input homophone usage frequency is compared with the threshold f.

As a result, if there is no word with a homophone usage frequency greater than the threshold value f, the process proceeds to usage frequency subroutine step 120, where all homophones are sequentially sent out in order of usage frequency, and these are displayed at display step 144. For example, if the frequencies of all the homophones corresponding to "Toki" are lower than the thresholds g and f, all the homophones are displayed in order of frequency of use, as shown at 171 in FIG. 15.

If there is a word with a homophone usage frequency greater than the threshold value f, the process proceeds to the next step 141, where it is determined whether there is one word with a homophone usage frequency greater than the threshold value f.

If it is a single word, the word is selected in step 142 and the process proceeds to a learning subroutine 143.

On the other hand, if there is one or more words, go to steps 145-1.
49, but this step is the first step.
Steps 119, 121, 122 in Figure 2
124 and 126, so a detailed explanation will be omitted, but in short, in step 145, the most frequently used same note is displayed, in step 146, lamp 7 is lit, and in step 147, it is determined whether or not the OK key 10 has been pressed. In step 148, it is determined whether or not the shift key 9 has been pressed.
This is to convert the homophone usage frequency of the word displayed in 9 to 0. When the OK key 10 is pressed, the program proceeds to step 143 to execute a learning subroutine, and then, in step 144, the selected word is displayed.

By executing all of the above-mentioned steps in this manner, it is possible to select the kanji corresponding to the input kana.

What is shown in FIG. 14 is a subroutine that outputs the most frequently used items in descending order of the frequency shown as step 120 in FIGS. 12 and 13. The number of area 37 (4 in FIG. 10) is added to the smallest address (n+2 in FIG. 10) corresponding to the heading of area 42 in the file, and the result of this addition is stored in RAM 33.
In this step, the data is stored in the a register.

After completion of step 150, step 1
In step 151, the smallest address (n+2 in FIG. 10) corresponding to the heading of the area 42 is stored in the b register of the RAM 33.

After completion of step 151, step 1
52, the second smallest address among the addresses corresponding to the heading of area 42 (n in FIG.
+3) is stored in the d register of the RAM 33.

After completion of step 152, step 1
53, the usage frequency stored at the address (n+2) stored in the b register (for example, 0.335 of the standard homophone usage frequency of area 81) is stored in the RAM 3.
Store in the e register of 3.

In the next step 154, the usage frequency (for example, 0.273) stored at the address (n+3) stored in the d register is similarly stored in the f register of the RAM 33.

After storing the frequency of use in e and f in this manner, the process proceeds to the next step 155, where it is determined whether the contents of the f register are smaller than the contents of the e register. When the usage frequency is stored as described above, e>f
Therefore, the program proceeds to the next step 156 and increments the contents of the d register by 21 (therefore, the contents of d become n+4).

After incrementing in this way, proceed to the next step 157 and determine whether the contents of the d register (n+4) and the contents of the a register match. If they do not match, proceed to the next step 158 and register the d register. The frequency (0.252) of the indicated address is stored in the f register and the process returns to step 155 again.

If e>f is not found in step 155, the process proceeds to step 159, in which the contents of the b register are incremented by 1, and it is determined in step 160 whether the contents of the b register and the contents of the a register bottom out. If they do not match, the process advances to step 161, and returns to step 155, where the frequency of the address indicated by 2 in the b register is stored in the e register.

If the contents of the d register and the contents of the a register match in step 157, the next step 16 is performed.
2, the frequency of the area 81 corresponding to the address stored in the b register is set to 0, and the process advances to step 163, where the kanji code on the file stored in the address indicated by the b register is sent out.

On the other hand, if the contents of the b register and the contents of the a register match in step 160, the next step 16 is performed.
4, the frequency of the area 81 corresponding to the address stored in the d register is set to 0, and the process advances to step 165, where the kanji code on the file stored at the address indicated by the d register is sent out.

In this way, step 163 or 165
The process advances to the next step 166 by completing the step 166, and the number of times this step 166 is passed reaches the area 3.
Determine whether it is equal to the number of homophones stored in 7,
If they are not equal, the process returns to step 151, and if they are equal, this subroutine is ended.

As mentioned above, in steps 163 and 165,
The purpose of setting the frequency of use in local register B to 0 is to set the frequency of use once selected to 0 so that in the next loop, the next highest frequency of use after the frequency of use set to 0 is selected.

In this way, if the kanji codes are output in order from the most frequently used kanji codes, the kanji codes are converted to kanji patterns and sequentially stored in the refresh memory 53.
Therefore, they are displayed on the display 27 in order of frequency of use as shown in FIG.

Therefore, when a plurality of words are displayed, the operator can select the winter period by operating the cursor key 2 and moving the cursor 174 to the winter period as shown.
