DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of Kana-Kanji conversion, and particularly for displaying a list of text strings to be converted when there are a plurality of conversion candidates to be selected. Related to technology.

[0002]

2. Description of the Related Art In conventional kana-kanji conversion processing, an input text string is subjected to morphological analysis, and the text string is divided into morphemes, which are the minimum units of vocabulary, and the type and part of speech of each morpheme are used. After recognizing information and the like, a corresponding conversion candidate is displayed for each text string of a predetermined unit such as one phrase based on the recognition result. If there are a plurality of conversion candidates at this display stage, the conversion candidates are ranked based on the past usage frequency and history, and the candidate with the highest rank is displayed as the first candidate first. However, if this first candidate is not your goal,
The remaining conversion candidates are listed in the order of the ranking.
Thereafter, when the user searches for and selects a target candidate from the list of candidates, the text string is replaced by the selected conversion candidate, and the conversion process is completed.

[0003]

Generally, one phrase is composed of an independent word having a meaning by itself, such as a noun, and an auxiliary word such as a particle or a conjugation ending. Also, in many cases, a text string for one sentence consisting of a plurality of kana characters can set a plurality of delimiter positions between independent words and attached words, and more than one conversion candidate is extracted for each delimiter position. There are many. In such a case, if the conversion candidates for the text string for one phrase are displayed by the conventional method, each conversion candidate will be displayed in a state where the delimiter position between the independent word and the attached word is different. .

FIG. 6 is a display example of a conversion candidate for a text string "Kaki ni", in which a conversion candidate in which the "Kaki" part is an independent word and only a "K" part in the text string are displayed. There are multiple pairs of conversion candidates to be independent words,
In addition, each candidate is displayed in a mixed manner. Therefore, it becomes difficult for the user to separate and separate the independent word portion of each conversion candidate, and it is very difficult to immediately select a target candidate. As described above, according to the conventional conversion candidate display method, it takes time for the user to find a target candidate, and the problem that the efficiency of the conversion work is significantly deteriorated occurs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems. It is an object of the present invention to display a list of a plurality of conversion candidates in such a manner that the separation positions between the independent words and the object words are arranged in a line. It is a technical object to quickly select a conversion candidate and significantly improve the efficiency of the kana-kanji conversion process.

[0014]

FIG. 1 shows the configuration of a kana-kanji conversion apparatus to which the present invention is introduced. This apparatus receives a text string input by a plurality of kana, and converts the text string into a text string mixed with kanji. The morphological analysis unit 1, the element separation unit 2, the narrow-down processing unit 3, the placement determination Part 4,
It comprises a homophone table 5, an input unit 6, a display unit 7, and the like.

The above kana-kanji conversion device is, specifically,
It is realized by a computer having a CPU 8, a ROM 9, and a RAM 10 as shown in FIG. That is, a CD-ROM in which a control program for realizing the functions of the respective units of the morphological analysis unit 1, the element separation unit 2, the narrow-down processing unit 3, and the arrangement determination unit 4 is stored in the CD-ROM drive 12 of this type of computer. By setting and installing the stored contents in the hard disk device 11, the CPU 8 has the function of each processing unit.
The homophone table 5 is created in the course of processing, is stored in the hard disk device 11 or the RAM 10, and is read and written by the CPU 8 as appropriate.

The input unit 6 includes a keyboard for inputting a text string, a mouse used for selecting a conversion candidate, and the like. The display unit 7 is a display device such as a CRT or a liquid crystal display panel, and displays a candidate display window described later, a conversion result of a text string, a display screen of an upper application, and the like.

The hard disk device 11 stores a control program for executing applications such as a word processor and a spreadsheet, in addition to the control program for the kana-kanji conversion device. CPU8
When a text string for kana-kanji conversion is input in the process of data input in these applications,
Using the function of the kana-kanji conversion device, the input kana-character text string is converted to a kanji-mixed text string. The conversion result is output to a work file being created on the application side, and is displayed at a data input position on the display unit 7.

Returning to FIG. 1, the configuration of each unit for realizing the kana-kanji conversion device of the present invention will be described. The morphological analysis unit 1 performs a morphological analysis on a text string (hereinafter, simply referred to as a “text string”) composed of a plurality of kana characters input from the input unit 6, and converts the text string into a morpheme that is a minimum unit of vocabulary information. It is divided for each word, and the part of speech of the word corresponding to each morpheme and the utilization information are recognized.

According to the morphological analysis described above, an independent word having an independent meaning and an auxiliary word attached before and after the independent word are separated and extracted. At this stage, the independent word and the auxiliary word are separated. The separation is slightly different depending on the morphological analysis method. Therefore, the next element separation unit 2 adjusts the result of the morphological analysis, using the stem of the noun or inflected word as an independent word, and a word that does not meet the requirements of the independent word such as a particle or an inflected ending as an adjunct. Further, the element separating unit 2 divides the input text string into phrase units each composed of a combination of an independent word and an adjunct, and separates a combination of an independent word and an adjunct corresponding to each phrase into a text in the phrase. Set as column conversion candidate.

In the course of morphological analysis, the text string is divided by a plurality of methods, and a plurality of words having the same pronunciation are often extracted. In this case, also in the element separation unit 2, the above-described adjustment processing and segmentation processing are performed for each extracted word, so that a text string for one phrase is finally determined by a combination of independent words and attached words. A plurality of conversion candidates will be set.

The homophone table 5 is for storing the conversion candidates set by the element separating section 2 into independent words and adjunct words. Fig. 3 is "Kakini"
This is a setting example of the homophone table 5 for a text string of one phrase, in which each set conversion candidate is separated and stored as its constituent independent words and attached words.

In the illustrated example, the words "below" and "persimmon" are used as independent words.
Nouns such as "summer", stems of verbs such as "writing" and "drawing", and "ka" in unconverted kana are set. Independent words corresponding to the pronunciation of "ki" are attached words. And the independent word corresponding to the pronunciation of "ka" is associated with "kini" as an auxiliary word.

Returning to FIG. 1 again, the arrangement determining unit 4 sets a candidate display window at a predetermined position on the display unit 7 and determines the arrangement of each conversion candidate in this window.
Control is performed based on the information in the homophone table 5. In this embodiment, the conversion candidates are arranged vertically in the candidate display window based on the order of use frequency and the like. The arrangement position is adjusted.

Further, the narrowing-down processing unit 3 executes a process of narrowing down each conversion candidate displayed in the display window based on a delimiter between an independent word and an attached word. The narrowing-down condition in this case is based on the narrowing-down condition input from the input unit 6, and the narrowing-down processing unit 3
Each conversion candidate in the homonym table 5 is narrowed down based on the input condition, and candidates that have been omitted from the narrowing are deleted from the homonym table 5. By activating the arrangement determining unit 4 in accordance with the updating process, only the conversion candidates corresponding to the input narrowing-down conditions are displayed in the display window.

FIG. 4A shows an example in which the conversion candidates are arranged in the candidate display window 15 based on the homophone table 5 shown in FIG. The independent words and the adjunct words are arranged vertically in a row so that the delimiters are aligned. Further, in this embodiment, in order to clarify the delimiter positions, the background portions 15a, 15a of the display region of the independent word and the display region of the attached word are used.
b is represented by different colors.

In the figure, 16 is a scroll bar, 17
Reference numerals a and 17b denote page turning bars. By operating the bars 16, 17a and 17b using a mouse, conversion candidates outside the display frame of the window 15 can be displayed. On the left side of each conversion candidate, a numerical option is displayed. A predetermined conversion candidate is selected by either inputting a number using a keyboard or positioning the cursor on the conversion candidate in the window 15 to confirm it. Is selected, and the selected candidate can be used to convert a text string for one phrase to be converted. In the illustrated example, the selection cursor is indicated by a horizontal line, and the conversion candidate (“writing”) to which the cursor is set is indicated by a bold font than the other candidates.

FIG. 4B shows a display example after narrowing down the candidate display window shown in FIG. 4A, in which "ka" and "ki" in the text string are separated. A display example when the position is specified is shown. The input of the narrowing-down condition is performed by selecting an arbitrary conversion candidate that satisfies the condition on the candidate display window 15 in the initial state. For example, when the user positions a cursor on a conversion candidate corresponding to a desired condition and operates a predetermined key (for example, a control key), a delimiter position in the candidate is captured and given to the narrowing-down processing unit 3. Therefore, after the narrowing-down process based on the separation position is performed, the candidates narrowed down by the arrangement determining unit 4 are rearranged in the candidate display window 15,
In the candidate display window 15, only the conversion candidates in which the independent word and the attached word are separated at the same position as the conversion candidate to which the cursor is set are displayed.

FIG. 5 shows the procedure of the CPU 8 for inputting a series of text strings in the specific device configuration shown in FIG. “ST” in the figure indicates each procedure. A program for executing this procedure is started by inputting a text string and performing a conversion operation in a process of executing a predetermined application. First, in ST1, input of a text string from the input unit 6 is performed. When accepted, in the next ST2, the text string is subjected to morphological analysis, the text string is divided into morpheme units, and a plurality of words are extracted.

Then, in ST3, the extraction result by the morphological analysis is adjusted by the function of the element separating unit 2,
A conversion candidate composed of an independent word and an auxiliary word is extracted for each phrase. Then, a homonym table 5 as shown in FIG. 3 is created for each phrase and stored in the hard disk device 11 or the RAM 10.

In the next ST4, a candidate display window 15 is set at a predetermined position on the display screen. In the window 15, each conversion candidate corresponding to the first phrase of the text string is displayed as an independent word and an adjunct word. The list is displayed with the break positions aligned in a line. In this state, when one of the conversion candidates is selected by the user, ST5 returns “YE”.
S ", the process proceeds to ST9, and the text string in the phrase to be converted is replaced with the selected conversion candidate. In response to this, the converted text string is displayed at the data input position on the display screen of the application being executed.

On the other hand, in the candidate display window displayed in ST4, if the operation of designating the break position as the narrowing condition is performed, ST6 becomes "YES" and the process shifts to ST7. In this ST7, the conversion candidates in the homophone table 5 are narrowed down to only those candidates where the independent word and the auxiliary word are separated at the designated position, and the display in the candidate display window is narrowed down. The display is updated to a list consisting only of candidates. When any one of the candidates is selected in the candidate display window after the update process, ST8 becomes "YES", and in ST9, the process of replacing the text string to be converted with the selected conversion candidate is performed.

In the following, the processing of ST4 to ST9 described above is performed for each of the clauses constituting the input text string, and the conversion to the text string containing kanji is sequentially performed. Upon completion, ST10 becomes "YES", and the input processing of the character data is completed.

As described above, even when a plurality of conversion candidates are extracted for a text string for one phrase, each conversion candidate is displayed in a list in which the delimiting positions of the independent word and the adjunct are arranged in one line. Therefore, the user can easily separate and recognize the independent word and the auxiliary word of each conversion candidate. Also, in this type of input processing, in most cases, the user recognizes information such as the length of a target word, the position of a separation between an independent word and an auxiliary word, and the type of kanji applied to the independent word. Therefore, a target conversion candidate can be easily and quickly found by displaying a list based on the delimiter position between the independent word and the attached word.

Also, when the target conversion candidate cannot be found immediately, the user inputs a narrowing-down condition by using another conversion candidate having the same position as the conversion candidate being searched as a delimiter position, and displays it. Since the conversion candidates in the window can be narrowed down, it is possible to easily input narrowing-down conditions and to narrow down the target conversion candidates without fail.

In the case of selecting a conversion candidate by the conventional method, it is necessary to search for a target conversion candidate from among a large number of conversion candidates displayed in a state where the break positions are not aligned. And it takes time to search. On the other hand, according to the refinement processing of this embodiment, only candidates in which the independent word and the auxiliary word are separated at the same delimiter position are displayed. The number of characters of the attached words is neatly ordered and easy to see, and it is possible to search for a target conversion candidate in a short time.

Further, according to the above-described conversion processing, a text string corresponding to a plurality of phrases can be input, and the conversion processing can be performed for each phrase. And the processing efficiency for inputting character data is significantly improved.

[0037]

According to the first, third, and fifth aspects of the present invention, a plurality of conversion candidates extracted from a text string are displayed in a list in such a manner that the separating positions of the independent words and the adjuncts are arranged in one line. On the display screen, the independent word part and the dependent word part of each conversion candidate are clearly separated, and the user can determine the length of the independent word of each conversion candidate and the type of kanji assigned to the independent word. A target conversion candidate can be easily found based on the information. Therefore, the processing time required for the kana-kanji conversion processing is greatly reduced, and efficient conversion processing can be performed.

In addition, according to the third and fifth aspects of the present invention, a text string corresponding to a plurality of clauses is input, a conversion candidate is displayed for each of the clauses in the above-described manner, a user's selection is accepted, and a conversion process is performed. Is performed, so-called continuous phrase conversion processing can be performed easily and at high speed, and processing efficiency for inputting character data can be significantly improved.

In each of the second, fourth and sixth aspects of the present invention, at the stage when each conversion candidate is displayed in a list, the designation of the delimiter position between the independent word and the dependent word is accepted, and the target of the list display is specified. Because only the conversion candidates where the independent word and the dependent word are separated at the delimiter position are narrowed down, the target conversion candidate is
It is possible to narrow down easily and reliably. In addition, the number of conversion candidates displayed by this narrowing process is reduced,
In addition, since the independent words and the dependent words are displayed with the same number of texts, the possibility of overlooking the conversion candidate is reduced, and the time for searching for the target conversion candidate can be greatly reduced.
