Description

Description: TECHNICAL FIELD The present invention relates to various information processing devices such as word processors, office computers, personal computers, data processors, workstations, etc., and particularly relates to an input device for Katakana in Japanese. 2. Description of the Related Art In general, various types of information processing apparatuses as described above have a katakana mode, which is set to a katakana mode immediately before a katakana character string is input and is then returned to the original mode after the character string is input. Also, there is one that converts a reading character string input in hiragana into katakana by a katakana conversion function. Of the two methods, the one described above is complicated and inefficient, since the operation of changing the current mode to katakana mode at the time of input and the operation of returning to the original mode after the input of katakana are inevitably involved. On the other hand, what is described later is divided into three keys: a key to convert kana to kanji, a key to confirm hiragana as it is in hiragana, and a key to convert hiragana to katakana.
It is necessary to use these keys properly according to the character string to be input, the operation is complicated, the possibility of erroneous operation is very high, and the efficiency is low. Therefore, in the current internationalization, the number of katakana words (foreign words) is very large, and there are many opportunities to input katakana in Japanese sentences, but as mentioned above, no sufficient means has been taken for this. Purpose The present invention has been made in view of the above points, and an object thereof is to improve the efficiency of katakana input in Japanese. Structure In order to achieve the above object, the present invention is applied to an information processing device capable of visually converting a kana-kanji character input from an input device into a kana-kanji character to be visually displayed on a display device. A kana-kanji conversion unit that appropriately converts a kana-kanji reading character into a kanji-kanji mixed sentence based on a word dictionary, and an undetermined character that has been appropriately converted into a kanji-kanji mixed sentence by the kana-kanji conversion device as a reading character from the cursor position. Katakana candidate group creating means for creating a katakana notation of the characters or character strings by dividing the acquired reading characters into a plurality of characters or character strings having different lengths, and the katakana candidate group Candidate selection means for selecting an appropriate one from a plurality of katakana notations created by the creation means, and katakana selected by the candidate selection means And katakana notation storage means for storing notations. Here, the kana-kanji conversion means has a function of referring to the katakana notation stored in the katakana notation storage means and converting the same reading character into katakana notation when the same reading character is input from the input device. doing.

The katakana candidate group storage area 18 stores all the outputs of the katakana candidate group creation circuit 17, and outputs this character data to the candidate selection circuit 15 and the katakana candidate group display data creation area 19. The katakana candidate group display data creation area 19 inputs character data in the katakana candidate group storage area 18, creates display data for sequentially displaying this, and outputs the display data to the display device 21. The word dictionary 20 stores information such as reading, notation, part-of-speech, and frequency of words, and outputs this word information to the kana-kanji conversion circuit 9. Katakana candidate group creation circuit among the above constituent circuits
Reference numeral 17 is a katakana candidate group creating means, candidate selection circuit 15 is a candidate selecting means for selecting an appropriate one from a plurality of katakana notation created by the katakana candidate group creating circuit 17, and learning data storage area 16 is a candidate selecting circuit. The katakana notation storage means for storing the katakana notation selected by 15 is configured respectively. The operation of this embodiment thus configured will be described with reference to FIG. 3 as a specific example of katakana input in a Japanese sentence. For example, as shown in (3) of FIG. 3, when the reading "I went to Kyonen Amerika went to" is input, the result shown by is obtained by the kana-kanji conversion processing. In this example, I want to enter "America" as "America," but in a system without a Katakana dictionary, "Ameka"
It becomes a coined word with no meaning. Therefore, by instructing the operation of changing "Rain science" to "America" and selecting "4" from the display by, you can convert "Amerika" to "America" like. You can When this converted katakana character string "America" is memorized and learned, and then the same reading "Amerika" is input, as shown in FIG. 3 (B), based on the learning data, Automatically convert to "America". In this way, Katakana words that frequently appear in the same document can be input by performing the correction work once without being aware that they are Katakana characters from the second time onward. Next, the operation of this embodiment will be described in detail with reference to the flowcharts of FIG. First, the processing at the time of input will be described with reference to FIG. When there is a key input from the input device 1, the next process determination circuit 2
It is determined whether is a cursor movement key, numeric input, conversion key, katakana conversion key, or hiragana key, and the data is transferred to each processing circuit according to the type of input data. When hiragana is input, it is sequentially stored in the read character string storage area 7 in the order of input. Reading character string input control circuit 6
Then, it is judged whether or not the number of hiragana characters in the reading character string storage area 7 has reached 6 characters (for example, 6 characters of "Iwahakyo" above), and when it reaches 6 characters, it is converted to the kana-kanji conversion circuit 9. Output the request. Until the number of characters reaches 6, the display data of the characters input by the reading character string display data creating circuit 8 is created and displayed on the display device 21. Next, the kana-kanji conversion process will be described with reference to the flow chart of FIG. 5 and the kana-kanji conversion process schematic diagram of FIG. The kana-kanji conversion circuit 9 takes in the reading data from the reading character string storage area 7, searches the learning data corresponding to this reading in the learning data storage area 16, determines whether there is learning data corresponding to the reading, and For example, the corresponding learning data is taken in as word information. In addition, the corresponding learning data is stored in the learning data storage area 16
If not, the word dictionary 20 is searched for a word corresponding to this reading. If there is a corresponding word, this word is extracted, and the reading and notation of this word are output to the undetermined information storage area 10 as shown in FIG. If there is no corresponding data in the word dictionary 20 as well, the first character of the reading data in the reading character string storage area 7 is cut out as one word in hiragana and the reading of that word is deleted from the reading character string storage area 7. If there is data corresponding to the learning data storage area 16 or the word dictionary 20, write the reading and notation of the word in the undetermined information storage area 10 as shown in FIG. 10, and read the reading "I", It is deleted from "I am Kyonen" in the reading character string storage area 7, "Hakyonen" remains as reading data, and this is sequentially converted. Then, the display data of the word is created by the undetermined candidate display data creation circuit 11 and displayed on the display device 21. Next, regarding the correction conversion processing, the flowchart of FIG.
This will be described with reference to the schematic diagram of the correction conversion process in FIG. When "I am a kanji" is displayed on the display device 21, an example of correcting and converting the "kanji" will be described. First, the correction conversion circuit 12 fetches the current cursor position from the cursor movement control circuit 3. Then, the corresponding reading character string N characters in the undetermined information storage area 10 are fetched. Here, N is the maximum number of read characters in the word dictionary 20, and is assumed to be “16”. Therefore, the reading length counter is set to N. For example, in FIG. 11, the five characters are "Kanjiji".
This is "Kanji", "Kanjide", "Kanji",
There are five types of readings, "kan" and "ka", and the word corresponding to each reading is searched in the word dictionary 20. Then, if there is this word, it is taken from the word dictionary 20 and this word information is accumulated in the candidate group storage area 13.
Then, the search is repeated in the word dictionary 20 for the next reading. At this time, if the word corresponding to reading is not in the word dictionary 20, the end of the reading character string is deleted and the value of the reading length counter is decremented by one. Then, it is determined whether or not the value of this counter is "0",
When it becomes "0", the word group that can be displayed simultaneously is cut out from the words accumulated in the candidate group storage area 13 by the candidate group display data creating circuit 14. In the example of Fig. 11, the "secretary" is cut out. Then, display data for displaying this word group is created. This "secretary" is displayed on the display device, and "kanji" is "secretary"
Convert to fix. Next, the katakana conversion process will be described with reference to the flowchart of FIG. 7 and the schematic diagram of the katakana conversion process of FIG. "I went to rain science last year" is displayed on the display device 21. To convert "rain science" into katakana, first, in the katakana candidate group creation circuit 17, the cursor movement control circuit 3
The current cursor position is fetched and the undefined information storage area
Take in 10 characters of the string corresponding to this reading in 10 (I went to Amerika). Then, the reading length counter is set to 1. From the beginning of this reading data, 1 character (A), 2 characters (Ame), 3 characters (Ame), 10 characters of Katakana notation are created, and as shown in Fig. 12, Katakana candidate group storage area
Accumulate to 18. At this time, the reading length counter is incremented by 1 for each character stored,
Then, it is determined whether or not the reading length counter reaches 10, and when the counter reaches 10, all 10 characters have been stored. Therefore, in the katakana candidate group display data creation area 19, the katakana candidate group storage area 18 is stored. From the displayed candidates, the words that can be displayed at the same time are cut out. In the example of Fig. 11, "America" is cut out. Then, display data for displaying this word group is created. As a result, "rain science" is converted to "America" and the display device
Display 21 "I went to America last year". Next, the candidate selection process will be described with reference to the flow chart of FIG.
This will be described with reference to the schematic diagram of candidate selection processing in the figure. The candidate selection includes correction conversion and katakana conversion. Here, candidate selection for katakana conversion will be described. As shown in the upper part of Fig. 13, "I went to rain science last year" is displayed on the display device 21, and 1 to 5 Katakana candidates are displayed below it. Select "4". The case will be described. First, the number "4" input from the input device 1 is fetched into the candidate selection circuit 15, "America" corresponding to this "4" is recognized, and it is determined whether or not the correction conversion is in progress. If correction conversion is not in progress, the word information "America" corresponding to this is selected from the katakana candidate group storage area 18 in the candidate selection circuit 15
Take in. If the correction conversion is in progress, the relevant word information “America” is taken into the candidate selection circuit 15 from the candidate group storage area 13. Next, the candidate selection circuit 15 rewrites the relevant portion in the undetermined information storage area 10 with the fetched word information. In this case, the two words "rain" and "science" in the unconfirmed information storage area 10 in FIG. 12 described above are replaced with one word "America" as in the unconfirmed information storage area in FIG. . Then, the data for displaying the selected word “America” is created by the undetermined candidate display data creation circuit 11 and displayed on the display device 21. Simultaneously with this display, the learning data of the selected word “Amerika⇒America” is written in the learning data storage area 16. Next, the cursor control method will be described with reference to the flow chart of FIG. 9 and FIGS. 11, 12, and 13. In Fig. 11, the cursor is located at the third word "Kan" in Fig. 12, Fig.
In FIG. 13, it is assumed that it is in the fourth word “rain” (indicated by C in FIG. 13). Input data of the cursor is input from the input device 1 to the cursor movement control circuit 3. The cursor position determining circuit 4 receives this data and fetches the word information designated by the current cursor position from the undetermined information storage area 10. As a result, it is determined whether to move the cursor to the left or right. Then, according to the result of this judgment, the word information of the words on the left and right is taken in. Based on this word information, the position and width of the new cursor are calculated. Then, the data for displaying the new cursor is created by the cursor display data creating circuit 5, and the data is displayed on the display device 21. Finally, the flow of kana-kanji conversion processing after learning "America" will be described with reference to FIG. 14 that summarizes the above-described processing. By the procedure shown in FIG. 5, the reading is converted into a mixture of kanji. First, the learning data storage area 16 and the word dictionary 20 are searched by reading the six characters of "Iwahakyo", "I" is cut out and stored in the unconfirmed information storage area 10. The conversion target reading is "ha Change to 6 characters "Kyonen". When the same process as above is repeated twice, three words “I”, “ha”, and “Kyonen” are cut out,
The six characters "Amerikahei" are the target readings. This time, since the learning data of "Amerika⇒America" exists in the learning data storage area 16, "America" is cut out as a word instead of "Rain + Science" as in the previous time. Thus, by carrying out the present invention,
By performing the work of converting a kana or kanji character string to katakana, the katakana words from the second time onward can be automatically converted from hiragana to katakana, and the efficiency of inputting Japanese sentences in which katakana is mixed is greatly increased. Can be increased. In addition, after the Kana-Kanji conversion process, it is possible to replace it with a katakana character string of any length, which eliminates the need to enter the hiragana and katakana breaks, as in the past, and makes it easier to input Japanese text. Can be increased. Effect According to the present invention, in a state in which the character string converted by the kana-kanji conversion means is undetermined, the katakana candidate group creation means imports the characters as reading characters and creates katakana notation. You can quickly create katakana notation. Further, the katakana candidate group creating means captures a character of arbitrary length as a reading character from the cursor position, divides the captured reading character into a plurality of characters or character strings having different lengths, and extracts these characters or character strings. Create the katakana notation for. Therefore, the operator only needs to set the conversion range one by one by pointing the cursor to the beginning of the character to be converted to katakana and instructing to select the appropriate one from the created multiple katakana notations. Without this, the conversion work can be performed easily and quickly. Moreover, the katakana notation that has been created and selected once is stored in the katakana notation storage means, and the kana-kanji conversion means executes conversion by referring to the stored katakana notation. And the workability of information processing is further improved.
