Abstract

PROBLEM TO BE SOLVED: To easily and surely select the conversion candidates by showing these candidates only in a part of a converted character string when a long read input character string is converted into a desired character string consisting of plural divided character units. SOLUTION: When a character 'TEION KANKYO' is inputted in HIRAGANA (cursive form of Japanese syllabary), the first KANJI (Chinese character) candidate of 'TEION KANKYO' is shown in a text area 20 of a display device 201 as a result of KANA (Japanese syllabary)/KANJI conversion. If an operator desires another KANJI string for 'TEION KANKYO', the first KANJI string shown in the area 20 must be corrected. A candidate display part 203 shows the candidate display example of the first words for the input character string 'TEION KANKYO' right after the start of correction. Thus, it's possible to easily and surely select the conversion candidates with no candidate character string got out of a display screen.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a computer or a word processor having a function of converting a kana character string input into a kana-kana mixed character string. More specifically, the present invention relates to a method and apparatus for displaying a conversion candidate character string associated with character string conversion. Conventionally, when a kana character string input is converted into a kana-kana mixed character string, a conversion result (conversion candidate) for the entire kana character string input designated by the operator as a conversion unit.
Is displayed on the screen of the display device at once. In addition, when there is a ambiguity in the conversion result, it is possible to enumerate and display all the ambiguities. However, as described above,
In the case of displaying the conversion result at a time corresponding to the entire character string input, or displaying the ambiguous meaning of the conversion result at a time, the conversion unit, that is, the kana character string input is, for example, a plurality of words or a plurality of words. When inputting a long character string consisting of phrases,
The conversion result (conversion candidate) corresponding to the character string input becomes longer and the number thereof also increases. As a result, a part of the conversion result (conversion candidate) is removed from the screen, and the desired conversion result (conversion candidate) is displayed. It becomes difficult to select visually from the displayed contents. It is an object of the present invention to make selection and correction easy and speedy when correcting the Kana-Kanji conversion result for a long character string input consisting of a plurality of words or a plurality of clauses, for example. It is an object of the present invention to provide a method and apparatus for displaying a conversion candidate character string. SUMMARY OF THE INVENTION The present invention is a phonetic character string conversion apparatus for converting a phonetic input character string, for example, a desired conversion candidate character string composed of a plurality of words or a plurality of clauses, such as a kana-kanji character string. At the time of the conversion operation, a desired conversion character string composed of the plurality of divided character units corresponding to the reading input character string and a conversion candidate character string corresponding to a part of the divided character unit of the conversion character string are simultaneously displayed on the same screen. When a desired conversion candidate character is selected from the conversion candidate characters corresponding to the divided character unit of a part of the converted character string, it corresponds to the next divided character unit following the divided character unit. This is a method for displaying conversion candidates for a phonetic input character string in which conversion candidate characters are automatically displayed. The present invention further comprises means for inputting a kana character string, kana-kanji conversion means for converting the kana character string input by the input means into a kanji-kana mixed character string consisting of a plurality of divided character units, A first display unit for displaying a kanji-kana mixed character string composed of a plurality of divided character units converted by the kana-kanji conversion unit at a sentence creation text position and corresponding to one divided character unit of the converted kanji-kana mixed character string. A display unit including a second display unit for displaying the conversion candidate character string, and a desired conversion candidate character string is selected from the conversion candidate character strings on the second display unit, and the selected conversion candidate character string is the first 1 means for replacing a part of the conversion character string at the text position of the display unit and displaying the conversion kanji / kana mixed character string and the conversion candidate character string on the same screen at the same time When a desired conversion candidate character string is selected from the conversion candidate character strings for the divided character unit of a part of the converted character string by the replacement means, the next divided character unit following the divided character unit is selected. The corresponding conversion candidate character is automatically displayed on the second display unit, and is a conversion candidate display device for reading input character strings. When a kana input character string is converted into a kanji / kana mixed character string consisting of a plurality of phrases, a conversion candidate corresponding to the one phrase is displayed on the same screen at the same time as the converted kanji / kana mixed character string. As a result, for example, the ambiguous display and selection of Kana-Kanji conversion such as a plurality of words or phrases and the correction operation can be efficiently performed. An embodiment of the present invention will be described below. FIG. 1 is a functional block diagram showing an embodiment of a Japanese sentence input device according to the present invention. In FIG. 1, a processing device 101 is a microprocessor, which reads and executes a program stored in a program memory 102, and controls each block and a data transfer control via a pass line 115. When a Japanese reading (reading input character string) desired to be input in kana or romaji is input from the key input device 107, a series of character codes corresponding to the reading is stored in the key code memory 106. In this case, the Japanese reading may be a word or a phrase, a plurality of phrases in which a plurality of them are consecutive, or a sentence from the beginning to a punctuation mark or a reading point. The character code string stored in the key code memory 106 is displayed every time one character is input.
Is written to the corresponding location of the refresh memory in the display device 112, that is, the cursor position of the display device 112 indicated by the cursor pointer 113. Display device 1
Reference numeral 12 scans the refresh memory at regular intervals, receives a character pattern in the character generator 110 corresponding to the character code through the display control circuit 111, and displays it. The key input device 107 may instruct the conversion of the input character sequence into a kanji-kana mixed sentence, either as a single word or phrase, or as a plurality of words or phrases, or at any time. Well, a combination of them may be used, but the unit for conversion is usually determined by the Japanese sentence input device used. What is suitable for the present invention is a character string (a plurality of divided character units) conversion unit including at least two or more words or clauses. The above conversion unit and the timing of actually executing the conversion may be the same, or some conversion units may be put together and the conversion may be executed at the same time. The same unit and the same conversion execution timing will be described. When an instruction to convert the input character sequence into a kanji-kana mixed sentence is given from the key input device 107, the program from the program memory 102 loaded into the processing device 101 is stored in the external storage device 114. The kana-kanji conversion is executed while referring to the contents of the term dictionary of (1) through the external storage device control circuit 113, and the kanji-kana mixed sentence is displayed on the text portion of the display device 112. The displayed kanji-kana mixed sentence is a sequence of terms and their connection information that are considered to be the most appropriate as a result of kana-kanji conversion. A specific example of the method of displaying the conversion result candidates will be described. For example, when a plurality of words or a plurality of phrases are converted into Kana-Kanji, the candidates are first displayed for the first word or a phrase. The conversion result is displayed on the display device. In this case, as a result of converting the input character string containing multiple words or phrases into kana-kanji characters, there may be cases where the delimiters of words or phrases are not uniform, but including those, the first character from the converted input character string is included. Only the conversion result of the word or phrase of is displayed on the display device. For example, if you take the display method of converting the character string "TEION KYOU" into kana and kanji and displaying it in word units,
"Low temperature" (two-letter idiom) and "low" (prefix) are displayed. The operator looks at the conversion result, and then performs a correction operation on a portion that is different from the desired conversion result. FIG. 2 shows a method in which the operator corrects the kana-kanji conversion result. 201 in FIG.
1 is the display device 112 in FIG. 1, and as a result of the kana-kanji conversion when "teionkankyo" is input as the input character string, "low temperature impression" is displayed in the text area 202. Now, if the character string desired by the operator is "low temperature environment", it is different from "low temperature sensation" shown in the text area 202, and therefore a correction work is required.
The display example of the candidate display unit 203 in FIG. 2 shows an example of the candidate display for the first word of the input character string “teiokankyoni” immediately after the correction work is started. FIG. 3 shows how to save the Kana-Kanji conversion result and how to use the result when correcting the Kana-Kanji conversion result, and FIG. 4 corrects the Kana-Kanji conversion result. An example of displaying the candidates on the display device 112 in this case and a procedure for selecting the candidates are shown, and the details of the present invention will be described using both FIG. 3 and FIG. 4. Referring to FIG. 3, the key input device 107 of FIG.
It is assumed that the input character string from is the same as in the example of FIG. Immediately after the correction operation is started, the method of cutting the word in the head part is limited to two types, "teion" and "tei". The former is a idiom and the latter is a prefix to the address A of the candidate accumulation unit. , The above two candidates are stored like 301, and the value of the address (A1 in this embodiment) where the candidate character string following this is stored after the character part of "low temperature" is Similarly, after "low", the value of the address (A2 in this embodiment) in which the candidate character strings following this are stored is also included. The display of the candidate of the head portion in FIG. 4 uses the information 301 in FIG. 3 above, and the character portion is first displayed as it is on the candidate display portion 203 of FIG. Then, the information following the character 301 is referred to, and if the information indicates an address other than 0, the candidate character displayed above is marked with "*". The information after the character in 301 is both non-zero addresses (A1 and A
2) is shown, the result of the display is that both of them are followed by "*" as shown in FIG. Next, the operator looks at 401 and selects the person who wants to input. To obtain the results shown in the example of FIG. 2, select “cold *” 401. The selection method is, for example, as shown in FIG.
Has keys corresponding to each of the three-tiered candidate areas,
This can be realized by pressing the key to select the displayed content. When "low temperature *" (the mark * indicates that a word continues after this) is selected from the two candidates currently displayed in 401, in 301 of FIG. The address A1 attached to the "low temperature" of the address A is referred to. Information after the address A1 has information 302, and candidate characters following "low temperature" are stored.
In other words, it means “to encourage”, “to the environment” and “between” (suffix). Similar to 301, information on characters following the character is stored behind each character, but in the case of 302, “0” is displayed after “to impress” and “to environment”.
Is in there. This indicates that there are no more characters following the character. After the "pause", it is indicated that the information of the succeeding character exists in the address A11. The candidate display for the portion 302 is as shown at 402 in FIG. In 402, the portion surrounded by [] indicates the portion already selected and established. Four
The candidate shown in 02 has two word delimiters, "Kankyo" (two-letter idiom) and "Kan" (suffix), and two-letter idiom has two words, "inspiration" and "environment". It shows that you have ambiguity. The two above 402 have no further characters, so if selected, all conversion results will be finalized. Since the lowermost candidate of 402 is further followed by characters, when this part is selected, the address A11 is referred to in 302 of FIG. The candidate for the address A11 is 303. The conversion result for "Kyoni" is written for the candidate of address A11, and as shown at 303, the results of "Today ni" and "Kyo ni" mixed with kanji and kana are obtained. Since it does not continue, the display is 403 in FIG.
If you select "Today" or "Kyo ni", all the characters will be set. On the other hand, when "Low *" in the second row of 401 is selected, the result for the remaining input characters "Okankankyoni" is shown as 304 in address A2 in FIG. Is written. The result of 304 is the conversion result of the part "Okan" of the remaining input characters "Okankankyo". In this case,
There is only one candidate, and the candidate display is as shown by 404 in FIG. When the uppermost row is selected in 404, the conversion result for the subsequent character "Kyoni" of "Okan" is
The address A21 is referred to from the information associated with the "pitch" of 304 in FIG. The address A21 is like 305, and the candidates for "today" are stored. The content of the address A11 of 303 is also the conversion result for "Kyuni" as in the case of 30 above. Differs from the above-mentioned idiom in that it also accepts the suffix "go" as a word following the idiom "tone". For 305, candidates are displayed as shown by 405 in FIG. That is, if the sentence desired to be input is "low temperature: environment", the operator selects "low temperature" from the above candidates. Immediately, "Environment" and "Emotion" are displayed as the conversion results for the remaining input characters "Kankyo". Then, select "Environment". If the character you want to input is "Low: Pitch: Town", select the candidate "Low" and the remaining character string "On Kankyo"
Since the first part of the conversion result for, "feeling" is displayed, select "feeling" and the remaining character string "Kyo"
The conversion result of "Go" is displayed. Furthermore, "town"
Select to get the desired conversion result. After performing the above operation, if the kana character is input through the key input device 107, the correction operation is completed and the next kana-kanji conversion can be performed. In FIG. 3, the selection at 304 was when there was only one candidate. In this embodiment, a method of selecting a candidate even when there is only one candidate is shown, but in this case, it is not always necessary to select the candidate itself. Therefore, it may be a keystroke or an instruction of a key indicating confirmation. According to the present invention, when a long reading input character string is converted into a desired converted character string composed of a plurality of divided character units, for example, a plurality of words or clauses, the conversion candidates are converted character strings. Since it is displayed by limiting it to a part of each, that is, one divided character unit, the conversion candidate character string does not go off the display screen, and it becomes possible to reliably and easily select the conversion candidate, The conversion candidate can be surely and easily selected, and the display processing speed can be increased, so that the operability can be improved. Further, according to the present invention, when a conversion operation is performed, a predetermined conversion character string and a conversion candidate corresponding to a divided character unit of a part of the conversion character string are simultaneously displayed on the same screen. Operation can be omitted and its operability is good.
