Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus such as a Japanese word processor. [0002] A typical method of inputting a character string is a direct input from a keyboard. As described in our Japanese word processor SWP-M55 Manual "Introduction to Sanword Manual", Kana-Kanji conversion device is used to input the Kana character string corresponding to the Kanji character string in response to the input of Roman key or Kana key. A device has been created which converts a character into a kanji in response to an input of a kanji conversion key. Press the kanji conversion key to convert the entered kana characters to kanji, press the katakana conversion key to convert to katakana, or press the no conversion key to keep the hiragana, and call the previous candidate. A document can be easily created by, for example, pressing a pre-conversion key. On the other hand, portable telephones such as PDCs and PHSs are small in size due to emphasis on portability. Most of them have only 10 keys for phone number input and some function keys, so the kanji conversion key, katakana conversion key, or no conversion key or previous conversion key necessary to enter Japanese You cannot have it independently. Therefore, there are only a few keys that can be used to convert input kana character strings to kanji or katakana, or to leave hiragana or to read out the last candidate. Conventionally, in a mobile phone, after inputting a kana character string,
When the kanji conversion key is pressed, the kanji character string candidates are called, the kanji character string candidates are sequentially called, and after the last kanji character string candidate is called, the katakana character string candidates are called. Conversely, after inputting a kana character string, pressing the pre-conversion key calls a kanji character string candidate in the opposite direction from the katakana character string candidate and the last kanji character string candidate. However, in the case of performing Kana-Kanji conversion in which the input character string is automatically segmented, the kana-kanji conversion instruction instructs the kana-kanji conversion to automatically cut a phrase and outputs a cut-off phrase candidate. Therefore, even if the final kanji conversion candidate is a katakana candidate, only the target phrase is converted to katakana, and the subsequent character string cannot be converted to katakana. [0006] An object of the present invention is to provide a device.
Because the emphasis is on portability of the
Katakana character string used in the document in kana-kanji conversion input device not including the katakana conversion key dedicated for converting Tacana string, hiragana input key and the forward
Kana-Kanji conversion key that instructs Kana-Kanji conversion
Using a pre-conversion key for instructing kana-kanji conversion allows input with little effort. [0007] In view of the above problems, the present invention has the following features. The invention according to claim 1 is characterized in that a character input unit, a first instruction unit for instructing a forward kana-kanji conversion, a second instruction unit for instructing a reverse kana-kanji conversion, and whether to perform segmentation. A kana-kanji conversion dictionary that associates a kana character string based on the result of the kana character string with a kana-kanji character based on a result of the determination means; Kana-kanji conversion means for converting a kana character string into a kanji mixed character string or katakana character string, and means for displaying characters, the kana kanji conversion means giving priority to the kanji mixed character string candidate over the katakana character string candidate The conversion is controlled, and conversion candidates are output in descending order of priority according to the first instruction means, and conversion candidates are output in descending order of priority in accordance with instructions from the second instruction means. In the call processing device, in the case of the kana-kanji conversion in the forward direction by the first instruction means, the phrase segmentation determination means activates the phrase separation means, and in the case of the reverse kana-kanji character conversion by the second instruction means, The phrase segmentation determining means controls the phrase segmentation means so as not to be activated. An embodiment of the present invention will be described with reference to FIGS. 1 to 19. FIG. 1 is a block diagram of the document processing apparatus. The control unit 1 performs input / output control and performs processing according to an instruction from the input unit 2. The input unit 2 includes input buttons (push buttons) and the like, executes various editing functions, sets various modes,
It specifies a character code string and inputs character data. The output unit 3 includes a CRT display, an LCD display, and the like.
Display menus, etc. The kana input buffer 4 is a buffer for storing a kana character string input from the input unit. The kana-kanji conversion dictionary 5 associates kanji character strings, which are readings of words, with grammatical information, such as kanji-kana mixed character strings, which are notations, and parts of speech of words. The phrase separation processing unit 6 divides the character string stored in the kana input buffer 4 into phrases using the information in the kana-kanji conversion dictionary 5 and stores the result in the phrase buffer 7. Phrase buffer 7
Is a buffer for storing the information of the phrase separation of the input kana character string. The kana-kanji conversion processing section 8 includes a phrase buffer 7
A Kana-Kanji mixed character string corresponding to the character string stored in the kana-kanji conversion output buffer 9 is generated. The katakana candidate generation unit 10 generates a katakana character string corresponding to the character string stored in the phrase buffer and stores it in the kana-kanji conversion output buffer 9. The specific operation of this device will be described with reference to FIG. In S0, the kana input buffer 4 is initialized. Normally, the input character string information is cleared. In addition, the kana character string returned from S10 described later may be reset. S1 converts an input operation from the input button of the input unit 2 into a signal and outputs the signal to the control unit 1. When obtaining the input signal from the input button, the control unit 1 performs the process of S2. S
Step 2 is a step of determining whether or not the input signal from the input unit 2 is a kanji (forward) conversion instruction. In the case of a kanji (order) conversion instruction, the process of S5 is performed. S3 is a step of determining whether or not the input signal from the keyboard of the input unit 2 is a kanji (reverse) conversion instruction. S for kanji (reverse) conversion instruction
A seven-step process is performed. S4 is a step of sequentially storing kana in the kana input buffer 4 when the input signal from the keyboard of the input unit 2 is a kana character string. FIG. 3 shows a kana character string "Matsuba Botanga".
Indicates the state in which is input. The input kana character string “Matsubabotan” is in a reversed state and is a kana-kanji conversion target character string. The cursor is located at the position of the last "GA" of the input kana character string, and up to this cursor position is a kana-kanji conversion target. FIG. 12 shows a state in which the input kana character string “Matsubabotanga” is stored in the kana input buffer 4. In this state, when a kanji (forward) conversion instruction is issued from the keyboard of the input unit 2, the processing in step S5 is performed based on the determination in step S2. In step S5, a process of dividing the input character string into phrases is performed. Using the word reading and grammatical information such as part of speech stored in the kana-kanji conversion dictionary 5, a character string input by an algorithm such as the longest match method or the minimum cost method is divided into phrases. In step S6, a character string corresponding to each phrase is stored in the phrase buffer 7. FIG. 13 shows a state in which the kana character string divided in step S5 is stored in the phrase buffer 7 for each phrase. Similarly, when a kanji (reverse) conversion instruction is issued from the keyboard of the input unit 2 in the state shown in FIG. 3 in the same manner as described above, the processing in step S7 is performed by the determination in step S3. In step S7, the input kana character string is stored in the phrase buffer 7 without being divided into phrases.
FIG. 14 shows a state in which the input kana character string is stored in the phrase buffer 7 without being divided in phrase units. In step S8, kanji conversion processing is performed using the kana-kanji conversion dictionary 5 based on the contents of the phrase buffer 7. At this time, priorities indicating the likelihood of the conversion candidates are assigned. Priorities are assigned based on the use frequency information of words stored in the kana-kanji conversion dictionary. The kanji mixed character string obtained by kanji conversion is stored in the kana kanji conversion output buffer 9 in order of priority. FIG. 15 shows the processing result of "Matsuba" in step S8. A candidate “Matsuba” is stored. FIG. 17 shows the result of processing "Matsubabotanga" in step S8. Since no kanji mixed character string is obtained, no candidates are stored. When step S8 is completed, katakana candidates are generated in step S9. The katakana candidate converts an input character string into katakana. JIS X0208
In the case of the "kanji code system for information exchange", the hiragana "a" is 2422 (hexadecimal) and the katakana "a" is 252.
2 (hexadecimal) as 100 in the hiragana code
By adding (hexadecimal), a katakana character string is obtained. In addition, considering that the ending of the character string has an attached word, a character in which the last character is hiragana is added as a candidate. The obtained katakana candidates are stored in a kana-kanji conversion output buffer 9. Here, only the last character is hiragana in consideration of the attached word, but two or three characters from the last character may be hiragana. Also,
Separately prepared an auxiliary word table such as "Ha, Ga, No",
The longest matching character string from the back may be used as a hiragana character string. FIG. 16 shows the result of processing "Matsuba" in step S9. In addition to “matsuba” in FIG. 15, katakana candidates “matsuba” and “matsuba” are stored in this order. FIG. 18 shows the processing result of "Matsubabotanga" in step S9. The katakana candidates “Matsuba button” and “Matsuba button” are stored in this order. In step S10, the output order of the kana-kanji conversion output buffer 9 is changed according to the kanji (forward) conversion instruction or the kanji (reverse) conversion instruction. In the kanji (order) conversion instruction, output candidates are output in the order of priority stored in the kana-kanji conversion output buffer 9 in the output unit 3.
Output and display. In step S10, the kanji (in order) is displayed until the display key is pressed and the display candidate is determined.
In the conversion instruction, the next candidate kanji (reverse) conversion instruction whose priority is lowered by one is displayed, and the next candidate whose priority is raised by one is displayed. In the case of a kanji (order) conversion instruction of “matsubabotanga”, “matsuba” is output and displayed on the output unit 3. The character string not used for the conversion is returned to the control unit 1. FIG. 4 shows a state in which output candidates are displayed. When a kanji (order) conversion instruction is input from the kana input display of FIG. 3, only the first phrase shown in FIG. 4 is converted. In this state, when the conversion confirmation key is operated, the state shown in FIG. 5 is obtained. Then, when a further kanji (order) conversion instruction is inputted, "botanga" of the second phrase is processed in the same manner as described above. The state is as shown in FIG. In this state, if a kanji (order) conversion instruction is continuously input, output candidates next to "botan" are displayed in order. The user only needs to operate the conversion confirmation key in the desired display state. FIG.
7 shows a state in which the conversion confirmation key is operated in the display state of FIG. When a kanji (reverse) conversion instruction is given to the kana input of "Matsubabotanga" in FIG. 8, the phrase separation processing is not performed by the processing of S3 and S7. As shown in FIG. 9, “Matsuba button mo”, which is the second candidate in FIG. 19, is displayed. When a kanji (reverse) conversion instruction is further input from this state, FIG.
"Matsuba button", which is the first candidate of No. 9, is displayed.
When the conversion confirmation key is operated in this state, the conversion confirmation state is displayed as shown in FIG. Although the embodiment according to the present invention has been described above, the present invention is not limited to this embodiment, and it goes without saying that various other modifications are possible. For example, in the above embodiment, when inputting a kanji (inverse) conversion instruction, output candidates are output and displayed in order from the one with the lowest rank, but instead,
When inputting a kanji (reverse) conversion instruction, the output may be performed in descending order of output candidates and displayed. In the above embodiment, the kanji conversion process (S8) is also performed when a kanji (reverse) conversion instruction is input. In such a case, the kanji conversion process (S8) is not performed and katakana conversion is performed. Only the candidate creation process (S9) may be performed. At least, when a kanji (reverse) conversion instruction is input first after inputting a kana character, it is highly likely that the user wants katakana conversion. Doing so can increase the processing efficiency. According to the present invention, emphasis is placed on portability of the device.
