Abstract

PURPOSE: To speedily select a conversion candidate on the KANA (Japanese syllabary)-KANJI (Chinese character) converting device by lightening the burden of key operation on a user who select a desired candidate out of conversion candidates. CONSTITUTION: This device is equipped with a next candidate selection part 314 which selects a conversion candidate having different word attributes by comparing the attributes of a word as a conversion candidate with the attributes of words as respective conversion candidates in a conversion candidate sequence; when indication input for a next candidate is specific indication input indicating a program search, the conversion candidate selected by the next candidate selection part 314 is displayed as the next candidate. Consequently, the next candidate is displayed by making a jump to a word having a different word attribute (length of reading of word stem, kind of part of speech, etc.), so the frequency of key operation for selecting the conversion candidate is greatly decreased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kana-kanji conversion device for converting an input reading character string into kana-kanji characters, and more particularly to a kana-kanji conversion device for facilitating selection of the next candidate of conversion candidates.

[0002]

2. Description of the Related 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 words (same phonemes) having the same reading but different meanings or feeds, for example, an input screen The corresponding word is indicated by an overline and displayed as a conversion candidate, and each time the user presses the function key indicating the next candidate, the next conversion candidate is displayed with a thick underline and the like. There is. For example, when "Kiku" is input and "Listen" is displayed although it is originally desired to be converted to "Chrysanthemum", the user continues to press the next candidate key until "Kiku" is displayed. Then, when "Chrysanthemum" is displayed, the function key for confirming is pressed to determine the conversion candidate.

As another example of the method of displaying the next candidate, for example, a display window is provided at the bottom of the screen, and a list of conversion candidates is displayed when the user presses a function key indicating the next candidate. A conversion candidate is selected from the conversion candidate list by moving the display (white display, etc.) showing the conversion candidate to be displayed each time the user presses the function key of the next candidate. Some are made available. In this case, the conversion candidates that do not fit in the display window are displayed by horizontal scrolling or the like. Then, when a desired conversion candidate is found in the display window, the function key for confirming is pressed to determine the conversion candidate.

[0004]

However, as described above, in the conventional kana-kanji conversion device, if the converted notation does not match the user's intention, for words with a large number of next candidates, conversion candidates in the window will be used. Even with the method of selecting the list of, many key operations are required. for that reason,
There is a problem that it takes time to search for and confirm a desired word, and the operation for selecting is troublesome.

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 key operation on the user who selects a desired candidate from among conversion candidates and to perform quick conversion. An object of the present invention is to provide a kana-kanji conversion device having a function of finding the next candidate that allows selection of candidates.

[0006]

The present invention relates to a kana-kanji conversion device for kana-kanji conversion of an input phonetic character string, and the above-mentioned object of the present invention is to convert the input phonetic character string into kana-kanji characters. While displaying the conversion result,
For a reading in which a homonym exists in the conversion result, a conversion candidate corresponding to the reading is extracted from the conversion candidate string and displayed, and the next candidate of the conversion candidate is input every time there is an instruction input of the next candidate for the conversion candidate. In the kana-kanji conversion device configured to sequentially display the conversion candidate strings in the order of arrangement, the attribute of the conversion candidate word and the attribute of each conversion candidate word in the conversion candidate string are compared to determine the word If the next candidate selection unit for selecting conversion candidates having different attributes is provided and the instruction input of the next candidate is a specific instruction input for instructing the cueing, the conversion candidate selected by the next candidate selection unit is set as the next candidate. It is achieved by making it visible.

[0007]

According to the present invention, when the next instruction selecting section for selecting a conversion candidate having a different word attribute from the currently displayed conversion target candidate from the conversion candidate string is provided, and a specific instruction is input. , The selected conversion candidate is displayed as the next candidate. As a result, the next candidate is displayed by jumping to a word having a different word attribute, so that the number of key operations when selecting a conversion candidate can be significantly reduced. For example, if the attribute of a word is "reading length of the stem," when you type "Kiku", even if you want to convert it to "Chrysanthemum" but "Listen" is displayed, press a specific key once. By doing so, a conversion candidate having a reading length of 1 is jumped, and “Chrysanthemum” having a reading length of 2 is displayed as a next candidate. Also,
When the attribute of a word is "type of part of speech", pressing a specific key once causes a jump from the verb conversion candidate string to the beginning of the noun conversion candidate string to display the next candidate. . Therefore, it becomes possible to easily search for and determine a desired candidate.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings. In the present embodiment, a method of displaying a list of conversion candidates in the window will be described as an example, but the present invention can be applied to a method of replacing and displaying conversion candidates on the input screen. In order to make the explanation easier to understand, the conversion candidate is a word in which the phrase is omitted, and a device having a color display function is taken as an example. The character string being input is “yellow”, and the conversion candidate is The description will be made assuming that the word is “light blue”, the finalized word is “white”, and the conversion candidates currently being converted (hereinafter, referred to as conversion target candidates) are white and are shown respectively.

FIG. 1 is a block diagram showing an example of a schematic structure of a kana-kanji conversion device having a function of finding the next candidate of the present invention. Each processing program, control data, etc. are stored in the ROM 2
, And the kana-kanji conversion unit 30 having the function of locating the next candidate is stored in the RAM 3. The kana-kanji conversion unit 30 converts the character string input from the input means 5 such as the keyboard 5a or the mouse 5b into the kana-kanji mixed character string from the reading character string by indexing the dictionary 4. 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 leading conversion candidate is shown as a white background as a conversion target candidate. When a specific key (hereinafter referred to as a “jump key”) for instructing the cueing of the next candidate is input, the attribute of the word of the conversion target candidate (for example, the reading length of the stem) is the attribute. It jumps to a different conversion candidate and shows the conversion candidate as a conversion target candidate. In the figure, a CPU that controls the entire system
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 are connected via a system bus 7 to mutually exchange data.

FIG. 2 shows a kana-kanji conversion unit 30 of the device of the present invention.
FIG. 3 is a block diagram showing an example of the functional configuration of FIG. 1. First, the outline of the present invention will be described with reference to FIG. Kana-Kanji conversion unit 30
Is an input / output control unit 31 for inputting a reading character string or a function key and outputting a Kana-Kanji conversion candidate or a result, and a Kana-Kanji candidate character string for the reading character string to the input / output control unit 31 by indexing the dictionary 4. It is composed of a kana-kanji conversion execution unit 32 to be supplied. The input / output control unit 31 has the following configuration.

The analysis unit 311 determines whether the input data is a character or a function key, further determines the input mode if it is a character, and converts it to "kana" if it is a Roman character input. Then, 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 phonetic character string stored in the storage unit 312 is transferred to the Kana-Kanji conversion execution unit 32.

The kana-kanji conversion executing unit 32 indexes the dictionary 4 and creates a conversion candidate character string for the reading character string. 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 having no homophone is shown in yellow, and a word (conversion candidate) having a homophone is shown in light blue, and the Kana-Kanji conversion result for the input character string is displayed on the CRT 6.

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 at the bottom of the screen. A list of conversion candidates is displayed in the window, and the first conversion candidate is displayed as a white background as a conversion target candidate. The extraction order here is the order stored in the kana-kanji conversion execution unit 32, and the order arranged by learning the usage frequency of the user.

On the other hand, the input data determined by the analysis unit 311 is a "jump key" for instructing the cueing of the next candidate.
If so, the next candidate selection unit 314 is called, and the next candidate cueing 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. Then, when a conversion candidate having different word attributes appears, the conversion candidate is displayed in the display window via the conversion result output unit 313 as a conversion target candidate.

Here, the word attribute is, for example, "length of stem reading" or "type of part of speech", and either attribute is set as an initial setting value. And which attribute should be used to find the next candidate (conversion target candidate):
It can be changed on the option setting screen (or the instruction with the function key for selecting the attribute). The word attribute may be, for example, “reading length of stem + type of part of speech”.

An operation example of inputting a kana-kanji conversion device having the function of finding the next candidate according to the present invention in such a configuration will be described in detail with reference to the flowcharts of FIGS. 3 and 4.

The character string input using the input means 5 such as the keyboard 5a and the mouse 5b is analyzed by the analysis unit 311 in the input / output control unit 31, converted into "kana" and converted into C
The reading character string is displayed on the RT6 and the reading character string is stored in the storage unit 312.
Stored in. At that time, the reading character string is segmented into segments and words, segment / part of speech classification and other segment / word information is created and stored in the storage unit 312 (step S1).
When the user explicitly presses the conversion key or when the "punctuation mark:.," Is input, the kana-kanji conversion execution unit 32 causes the reading character string transferred from the analysis unit 311 to be read. Is input, and the conversion result for the reading character string is stored in the storage unit 312.

Subsequently, in the conversion result output unit 313 in the input / output control unit 31, a character string having no homophone is shown in yellow, and a word having the homophone is shown in light blue, and the kana-kanji for the input character string is used. The conversion result is displayed on the CRT 6 (step S2). The user looks at the kana-kanji conversion result and, if the notation does not match the intention, presses the function key indicating the next candidate.

When the analysis unit 311 confirms the input of the function key designating 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 the CRT 6 Display a list of conversion candidates in the display window of. For example, if the user inputs "hiding", and "each" is displayed as a conversion candidate on the input screen as shown in FIG. 4 (A), by inputting a function key indicating the next candidate, If the number of next candidates is a predetermined number (for example, three) or more, a list of conversion candidates is displayed as much as the number of candidates fits in the window. At that time, the top conversion candidate is displayed as a conversion target candidate (hatched portion in FIG. 9A: the entire conversion target candidate is displayed in reverse (white) display) and the conversion candidate on the input screen is changed to “kana”. And display it (step S4).

When the user further inputs the function key indicating the next candidate (steps S5 and S6), the conversion result output unit 313 displays one conversion candidate in the relevant direction in the list display in the display window. The outline display showing the conversion target candidates is moved and displayed. The method of selecting the conversion candidate by the key operation of the next candidate is the same as the conventional technique. For example, if the user wants to select “7. Cabinet” in the display example of FIG. 4A, the user presses the next candidate key 6 times to select it. If it is not displayed in the window, the next candidate key is further pressed to search for a desired conversion candidate (step S7).

On the other hand, if the input data determined by the analysis unit 311 is a "jump key" for instructing the cueing of the next candidate (step S8), the next candidate selection unit 314 is called and the next candidate is selected. Cue processing is performed. The next candidate selection unit 314 compares the attribute of the word of the current conversion target candidate with the attribute of the word of each conversion candidate 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 makes the above comparison based on the word information. For example, if the word attribute is set to "word stem reading length", the "word stem reading length" of the conversion candidate and the conversion candidate to be compared is extracted from the word information, and the two are compared. . If the word attribute is set to “type of part of speech”, the part of speech classification (information indicating a noun, verb, etc.) is extracted from each word information and the two are compared.

When a conversion candidate having a different attribute appears in the conversion candidate string, the conversion candidate is displayed in the display window as the conversion target candidate via the conversion result output unit 313. For example, the attribute of a word is “reading length of stem”
If it is set to, jumping to "ku" with different reading length of the stem, as shown in FIG. 4 (B),
"Ku" is displayed as a conversion target candidate. that time,
If the jumped conversion target candidate is not displayed in the display window, the conversion target candidate is set to the head position (or the horizontal conversion is performed to make the conversion target candidate a predetermined (center, end, etc.) position). Display a list.
Further, when the jumped conversion target candidate is displayed in the display window, as shown by the arrow in FIG. 7C, the word stem is changed from "1. Notification" to "7. Dark". Jump to the beginning of the conversion candidates with different reading lengths and display the conversion target candidates.

By providing such a function for finding the next candidate, the number of key operations for selecting the next candidate is significantly reduced. Note that the cueing process here is the same even when the array of the conversion candidate list is in a state in which the learning function is in a state in which word attributes are mixed. For example, assuming that the attribute of a word is set to a part of speech and the sequence of conversion candidates is “1. noun, 2. verb, 3. verb, 4. noun, 5. verb ... Every time you press the key, 2 → 4 →
The display of the conversion target candidate moves such as 5. However,
Without comparing with the attribute of the word of the current conversion target candidate,
The attribute of the conversion target candidate word displayed first is compared, and each time the jump key is pressed, 2 → 3
The display of the conversion target candidates may be moved as → 5. Alternatively, 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 of attributes that are different from the attributes of the current conversion target candidate, and displays the list from the beginning of the group. You may make it perform (step S9).

When the cueing process of the next candidate in step S9 is completed, the process returns to step S5 and the above operation is repeated. If all the conversion candidates have been decided, the next sentence or the like is awaited for input, and the process ends.

[0025]

As described above, according to the kana-kanji conversion device having the function of locating the next candidate of the present invention, the next candidate is displayed by jumping to a word having a different word attribute, so that the conversion candidate is selected. The number of key operations can be significantly reduced. Therefore, it is possible to reduce the burden of key operation on the user who selects a desired candidate from the conversion candidates,
It is possible to quickly select conversion candidates.
