Description

[0001]
[Industrial application fields]
The present invention relates to a kana-kanji conversion device that converts an input reading character string into kana-kanji characters, and more particularly to a kana-kanji conversion device that can easily select a next candidate for conversion.
[0002]
[Prior art]
Conventionally, in a kana-kanji conversion device, in the process of converting an input reading character string into a kana-kanji mixed character string, for a word (sound word) that has the same reading but different meaning and feed, for example, the corresponding word on the input screen Are displayed as conversion candidates, and each time the user presses a function key indicating the next candidate, the next conversion candidate is displayed with a bold underline or the like. For example, when “Kiku” is input and “Listen” is displayed even though it is originally intended to be converted to “Chrysanthemum”, the user continues to press the next candidate key until “Chrysanthemum” is displayed. Then, when “chrysanthemum” is displayed, the function key indicating confirmation is pressed to confirm the conversion candidate.
[0003]
As another example of the next candidate display method, for example, a display window is provided at the bottom of the screen, and a list of conversion candidates is displayed in the display window when the user presses a function key indicating the next candidate. Each time the user further presses the function key of the next candidate, the conversion candidate can be selected from the list of conversion candidates by moving the display indicating the target conversion candidate (such as white display). Some have done. In this case, conversion candidates that do not fit in the display window are displayed by horizontal scrolling or the like. If a desired conversion candidate is found in the display window, the conversion candidate is confirmed by pressing a function key indicating confirmation.
[0004]
[Problems to be solved by the invention]
However, as described above, the conventional Kana-Kanji conversion device is a method of selecting a list of conversion candidates in the window for words having a large number of next candidates when the notation after conversion does not match the user's intention. However, many key operations are required. Therefore, there are problems that it takes time to search for and determine a desired word and that the operation for selection is troublesome.
[0005]
The present invention has been made under the circumstances as described above, and an object of the present invention is to reduce the burden of a key operation of a user who selects a desired candidate from among conversion candidates, and to quickly select conversion candidates. It is an object of the present invention to provide a kana-kanji conversion device having a cueing function for next candidates.
[0006]
[Means for Solving the Problems]
The present invention relates to a kana-kanji conversion device for converting an input reading character string into kana-kanji characters, and the object of the present invention is to convert the input reading character string into kana-kanji characters, display the conversion result, and perform the conversion. For a reading in which a homonym is present in the result, a conversion candidate corresponding to the reading is extracted from the conversion candidate string and displayed, and the next candidate for the conversion candidate is displayed each time there is an instruction input for the next candidate for the conversion candidate. In the kana-kanji conversion device, which is sequentially displayed in the arrangement order of the conversion candidate sequence, the attribute of the word is obtained by comparing the attribute of the conversion candidate word with the attribute of each conversion candidate word in the conversion candidate sequence. If a next candidate selection unit that selects different conversion candidates is provided, and the instruction input of the next candidate is a specific instruction input instructing cueing, the conversion candidate selected by the next candidate selection unit is selected. It is achieved by the displayed as candidates.
[0007]
[Action]
The present invention includes a next candidate selection unit that selects a conversion candidate having a word attribute different from that of the currently displayed conversion target candidate from the conversion candidate string, and is selected when a specific instruction is input. The converted candidate is displayed as the next candidate. As a result, the next candidate is displayed by jumping to a word having a different attribute, so that the number of key operations when selecting a conversion candidate can be significantly reduced. For example, if the word attribute is “stem reading length”, when you enter “Kiku”, even if you want to convert it to “Chrysanthemum” but “Listen” is displayed, press a specific key once As a result, the conversion candidate having the stem reading length of 1 is jumped, and “chrysanthemum” having the reading length of 2, etc. is displayed as the next candidate. If the word attribute is “part of speech”, pressing a specific key once, for example, jumps from the verb conversion candidate string to the top of the noun conversion candidate string and displays the next candidate. Is done. Therefore, a desired candidate can be easily searched and determined.

【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this embodiment, a method for displaying a list of conversion candidates in a window will be described as an example. However, the present invention can also be applied to a method in which conversion candidates on an input screen are replaced and displayed. In order to make the explanation easy to understand, the conversion candidate is an abbreviation of a phrase and a case of a word. Further, an example of a device having a color display function is used. The description will be made assuming that the word is “light blue”, the finalized word is “white”, and the conversion candidates that are currently converted (hereinafter referred to as conversion target candidates) are outlined, respectively.
[0009]
FIG. 1 is a block diagram showing an example of a schematic configuration of a kana-kanji conversion device having a cueing function for a next candidate according to the present invention. Each processing program, control data, and the like are stored in the ROM 2 and the RAM 3, and the next candidate A kana-kanji conversion unit 30 having a cueing function is stored in the RAM 3. In the kana-kanji conversion unit 30, the character string input from the input means 5 such as the keyboard 5a or the mouse 5b is indexed in the dictionary 4 and converted from the read character string into a kana-kanji mixed character string. When displaying the next candidate, the kana-kanji conversion unit 30 displays a list of conversion candidates in a display window provided at the bottom of the input screen. At that time, the top conversion candidate is shown as a white candidate as a conversion target candidate. When a specific key (hereinafter referred to as a “jump key”) for instructing the search for the next candidate is input, the attribute of the conversion target candidate word (for example, the length of reading of the stem) It jumps to a different conversion candidate and shows the conversion candidate as a candidate for conversion. In the figure, a CPU 1, a ROM 2, a RAM 3, a dictionary 4, an input means 5, such as a keyboard 5a and a mouse 5b, and a CRT 6 that perform overall control are connected via a system bus 7 to exchange data with each other.
[0010]
FIG. 2 is a block diagram showing an example of the functional configuration of the kana-kanji conversion unit 30 of the device of the present invention. First, the outline of the present invention will be described with reference to FIG. The kana-kanji conversion unit 30 inputs the input character string and function key, and outputs the input / output control unit 31 for outputting the kana-kanji conversion candidates and results, and the input / output of the kana-kanji candidate character string for the read character string by indexing the dictionary 4. The kana-kanji conversion execution unit 32 is supplied to the control unit 31. The input / output control unit 31 has the following configuration.
[0011]
The analysis unit 311 determines whether the input data is a character or a function key. If the input data is a character, it further determines the input mode, and if it is a Roman character input, converts it to “Kana”. The converted reading character string is stored in the storage unit 312, and the reading / character string is analyzed and the phrase / word information is stored in the storage unit 312. If the input data is a function key for instructing conversion, the read character string stored in the storage unit 312 is transferred to the kana-kanji conversion execution unit 32.
[0012]
The kana-kanji conversion execution unit 32 creates an conversion candidate character string for the reading character string by indexing the dictionary 4. The conversion candidate character string output from the kana-kanji conversion execution unit 32 is stored in the storage unit 312 as a conversion result. In the conversion result output unit 313, a character string in which no homophone is present is shown in yellow, and a word (conversion candidate) in which the homophone is present is shown in light blue, and a Kana-Kanji conversion result for the input character string is displayed on the CRT 6.
[0013]
If the input data determined by the analysis unit 311 is a function key indicating the next candidate, the conversion result output unit 313 extracts the conversion candidate character string from the storage unit 312 and displays it in the display window at the bottom of the screen. A list of conversion candidates is displayed, and the first conversion candidate is displayed in white as a conversion target candidate. The extraction order here is the order stored in the kana-kanji conversion execution unit 32, and is the order in which the usage frequency of the user is learned and arranged.
[0014]
On the other hand, if the input data determined by the analysis unit 311 is a “jump key” instructing the search for the next candidate, the next candidate selection unit 314 is called, and the next candidate search process is performed. The next candidate selection unit 314 extracts the conversion candidates stored in the storage unit 312, compares the attribute of the word with the current conversion target candidate, and repeats the extraction process until a conversion candidate having a different word attribute appears. When conversion candidates having different word attributes appear, the conversion candidates are displayed as conversion target candidates in the display window via the conversion result output unit 313.
[0015]
Here, the word attribute is, for example, “stem length” or “part of speech”, and one of the attributes is set as an initial setting value. Then, with which attribute the next candidate (conversion target candidate) is cued can be changed on the option setting screen (or an instruction with a function key for selecting an attribute). Further, the attribute of the word may be, for example, “reading length of word stem + type of part of speech”.
[0016]
In such a configuration, an operation example of input of a Kana-Kanji conversion device having a cue function for the next candidate of the present invention will be described in detail according to the flowcharts of FIGS.
[0017]
The character string input using the input means 5 such as the keyboard 5a or the mouse 5b is analyzed by the analysis unit 311 in the input / output control unit 31, converted into "kana", displayed on the CRT 6, and read character string. Is stored in the storage unit 312. At this time, the reading character string is divided into phrases and words, and phrase / word information such as a break and part of speech classification is created and stored in the storage unit 312 (step S1). When the user explicitly presses the conversion key or when “Punctuation ::” is input, the kana-kanji conversion execution unit 32 reads the read character string transferred from the analysis unit 311. And the conversion result for the reading character string is stored in the storage unit 312.
[0018]
Subsequently, in the conversion result output unit 313 in the input / output control unit 31, a character string in which no homophone is present is shown in yellow, a word in which the homonym is present is shown in light blue, and a Kana-Kanji conversion result for the input character string is displayed. Display on the CRT 6 (step S2). The user looks at the Kana-Kanji conversion result, and if the notation does not match the intention, the user presses a function key that indicates the next candidate.
[0019]
When the analysis unit 311 confirms the input of the function key for instructing the next candidate (step S3), the conversion result output unit 313 extracts the conversion candidate character string for the conversion candidate from the storage unit 312 and displays the display window of the CRT 6 A list of conversion candidates is displayed. For example, if the user inputs “Kaku” and “Each” is displayed as a conversion candidate on the input screen as shown in FIG. 4A, the function key that indicates the next candidate is input. If the number of next candidates is greater than or equal to a predetermined number (for example, 3), a list of conversion candidates is displayed for the amount that fits in the window. At that time, the first conversion candidate is displayed as a candidate for conversion (shaded area in FIG. 5A: the entire conversion target candidate is inverted (white)), and the conversion candidate on the input screen is changed to “Kana”. Is displayed (step S4).
[0020]
When the function key indicating the next candidate is further input by the user (Steps S5 and S6), the conversion result output unit 313 displays one conversion candidate in the direction in the list display in the display window. The white display indicating is moved and displayed. The conversion candidate selection method by the key operation of the next candidate is the same as that of the conventional technique. For example, if it is desired to select “7. Kaku” in the display example of FIG. 4A, the user selects the next candidate key by pressing it six times. If not displayed in the window, the next candidate key is further pressed to search for a desired conversion candidate (step S7).
[0021]
On the other hand, if the input data determined by the analysis unit 311 is a “jump key” instructing the search for the next candidate (step S8), the next candidate selection unit 314 is called and the next candidate search process is performed. Is done. The next candidate selection unit 314 compares the attribute of the current conversion target candidate word with the attribute of each conversion candidate word in the conversion candidate string stored in the storage unit 312. Here, the attribute of the word is stored as word information by the processing in the analysis unit 311, and the next candidate selection unit 314 performs the above comparison based on the word information. For example, if the word attribute is set to “stem reading length”, the “stem reading length” of the conversion candidate and the conversion candidate to be compared is extracted from the word information and compared. . If the attribute of the word is set to “type of part of speech”, the part of speech classification (information indicating noun, verb, etc.) is extracted from each word information and compared.
[0022]
When conversion candidates having different attributes appear in the conversion candidate string, the conversion candidates are displayed as conversion target candidates in the display window via the conversion result output unit 313. For example, if the word attribute is set to “stem reading length”, jump to “writing” having a different stem reading length, and as shown in FIG. "" Is displayed as a candidate for conversion. In this case, if the jumped conversion target candidate is not displayed in the display window, the conversion target candidate is set to the start position (or the conversion target candidate is set to a predetermined position (center, end, etc.) by sequentially scrolling horizontally. To display the conversion candidate list. Further, when the jumped conversion target candidate is displayed in the display window, as indicated by the arrow in FIG. 5C, from “1. notification” to “7. Jump to the top of conversion candidates with different reading lengths and display conversion target candidates.
[0023]
By providing such a next candidate cueing function, key operations in selecting the next candidate are significantly reduced. The cueing process here is the same even when the array of conversion candidate lists is in a state in which word attributes are mixed by the learning function. For example, if it is assumed that the attribute of the word is set to part of speech and the conversion candidate array is “1. noun, 2. verb, 3. verb, 4. noun, 5. verb ...”, jump Each time the key is pressed, the display of the candidate for conversion moves in the order of 2 → 4 → 5. However, instead of comparing the attribute of the current candidate word for conversion with the reference, the comparison is made based on the attribute of the first candidate word to be converted, and every time the jump key is pressed, 2 → You may make it move the display of the candidate for conversion like 3 → 5. Alternatively, groups of words with the same attribute are grouped and arranged, and each time the jump key is pressed, the list jumps to the beginning of the group whose attribute is different from the attribute of the current candidate for conversion and displays a list from the top of the group You may make it carry out (step S9).
[0024]
When the next candidate cueing process in step S9 is completed, the process returns to step S5 and the above operation is repeated. If all the conversion candidates are confirmed, the process waits for input of the next sentence and the process ends.
[0025]
【The invention's effect】
As described above, according to the kana-kanji conversion apparatus having the next candidate cuing function of the present invention, the next candidate is displayed by jumping to a word having a different word attribute. The number of times can be significantly reduced. Therefore, it is possible to reduce the burden of the key operation of the user who selects a desired candidate from among the conversion candidates, and it is possible to quickly select conversion candidates.
