Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a kana-kanji conversion apparatus, and more particularly to a kanji conversion apparatus that converts at least an input kana character string into a plurality of kana-kanji mixed character string candidates and displays the candidates.
[0002]
[Prior art]
A kana-kanji conversion device created for the purpose of handling Japanese on a computer inputs a kana character string and converts it into a kanji-kana mixed sentence. The performance of the Kana-Kanji conversion device has been greatly improved, and the conversion accuracy itself is reaching a practical level due to the examination of dependency between phrases and the adoption of the minimum cost method. Therefore, a more advanced service is required for the kana-kanji conversion device.
[0003]
Some document editing devices such as word processors have a document proofreading function. For example, an inappropriate expression, a word, or the like is detected and displayed for identification. Also, some kana-kanji conversion devices have been controlled so as not to display inappropriate candidates when displaying converted kana-kanji mixed character string candidates.
[0004]
[Problems to be solved by the invention]
However, it is inefficient to use a proofreading function such as a word processor after input by a kana-kanji conversion device as in the prior art, and it is desirable to detect at the stage of the kana-kanji conversion device.
[0005]
Also, the conventional kana-kanji conversion device that can detect inappropriate words and the like handles character string candidates mixed with kana-kanji after conversion. Therefore, it is not possible to detect kanji in the candidate in units of characters. Specifically, there is a case where the candidate “day of the week” “Monday” is not acquired in the specific grade of the elementary school and “Monday” is written. At this time, in the conventional kana-kanji conversion device, “Monday” itself is not displayed as a candidate, or “Monday” as a whole is identified and displayed. Therefore, the user cannot know which character in “Monday” is a problem.
[0006]
Further, in the conventional kana-kanji conversion device, in the above example, after “Monday” is detected as inappropriate, it is necessary to re-input “Month”, “Yo”, and “Day” individually. It is more preferable to perform the operation of replacing “day” with “yo” at the time when “Monday” is detected during kana-kanji conversion. In particular, it is desirable to activate a means for replacing an aphoric word, an in-house document prohibited word, etc. with an appropriate expression upon detection.
[0007]
The present invention has been made to solve the above problems, and an object of the present invention is to provide a kana-kanji conversion device that detects inappropriate expressions in units of characters and informs the user. It is another object of the present invention to provide a kana-kanji conversion device having a function of replacing a detected character with an appropriate expression.
[0008]
[Means for Solving the Problems]
The kana-kanji conversion device of the present invention is a kana-kanji conversion device that analyzes an input kana character string with reference to a dictionary and converts it into a kana-kanji mixed character string, and searches the kana-kanji conversion dictionary from the kana-character string A kana-kanji conversion unit that creates a plurality of kana-kanji mixed character string candidates, a special character dictionary that stores a special character consisting of a single kanji character, and characters that constitute the kana-kanji mixed character string candidate and the special character dictionary A special character search unit that adds an identifier to the matched character in units of one character, an identification display instruction unit that treats the character having the identifier as a special character, and instructs to identify and display other characters, A candidate display creation unit that creates a candidate display of a part or all of the kana-kanji mixed character string candidates based on an instruction from the identification display instruction unit, and among the kana-kanji mixed character string candidates, A special character replacement unit including a kana character replacement unit that searches the replacement dictionary for the special character to be replaced with a kana character by performing a predetermined operation on the displayed character having the identifier, The special character replacement means includes replacement candidate learning means for registering a kana-kanji mixed character string candidate created by a replacement operation in the kana-kanji conversion dictionary.
[0009]
The above-described kana-kanji conversion device searches the special character dictionary for the candidates created by the kana-kanji conversion unit, and discriminates the special characters for each character in the candidates. A special identifier is attached to the special character, and other characters are identified and displayed. Therefore, identification display can be performed for each character constituting a character string candidate mixed with kana and kanji.
Also, special characters are often displayed because their use is restricted, and it is very effective to replace the special characters with appropriate characters.
In the kana-kanji conversion device, the special character replacement means includes a kana character replacement unit that searches the replacement dictionary for the special character to be replaced and converts it into a kana character. Therefore, when kanji by grade is detected, it can be replaced with kana characters.
In the kana-kanji conversion apparatus, the special character replacement means includes replacement candidate learning means for registering a kana-kanji mixed character string candidate created by a replacement operation in the kana-kanji conversion dictionary. For example, if “Monday” replaced with “Monday” is registered in the kana-kanji conversion dictionary, “Monday” and “Monday” will be displayed as conversion candidates from the next time, making selection easier.
[0010]
In addition, the identification display instruction unit includes a display mode change instruction unit that instructs to change the display mode of the special character itself from other characters when the special character can be distinguished from other characters. Since it is a feature, it can be identified and displayed as a special character detected by color coding or the like, and the convenience of the user is improved.
[0011]
In addition, the special characters are classified into a plurality of types, a type identifier storage unit that stores an identification identifier corresponding to the type of the special character in the special character dictionary in association with the special character, and the special character search A type identifier search unit for searching for the type identifier corresponding to the special character searched by the type, and the character string mixed with the kana / kanji characters so as to be distinguished from other characters or other special characters according to the type of the type identifier A special character identification display instruction unit for instructing display of candidates. That is, the kana / kanji device further classifies the special characters into a plurality of special characters and has a type identifier corresponding to the type of each special character. Therefore, identification display according to the type of special character is possible.
[0012]
On the other hand, it is also effective that the kana-kanji conversion device includes a condition setting unit that sets the identification display method in the identification display instruction unit and the presence / absence of the identification display corresponding to the identifier. The condition setting unit can set the display condition of each special character, that is, the display method such as the presence / absence of display and the display color according to the type of document to be created. The types of special characters include at least personal characters, emergency kanji, and kanji for each grade. For example, when creating a document for a specific grade, it is possible to identify and display kanji acquired in a grade higher than that grade. .
[0013]
The kana-kanji conversion device includes a guidance display unit that displays guidance about the special character simultaneously with the special character identification display or by a predetermined operation after the special character identification display. You can easily know why the special characters were searched.
[0015]
In addition, the special character replacement means includes a synonym character replacement unit that searches the replacement dictionary for the special character to be replaced and converts it into a synonym character. It can be replaced with other expressions.
[0019]
Furthermore, since the guidance or the menu is displayed in the vicinity of the special character that is identified and displayed, the user can view the guidance display and the menu display in association with the displayed special character.
[0022]
Other aspects of the invention
As other aspects of the present invention, various aspects can be considered such that the input means is a handwriting recognition means, an optical character reader such as a scanner, and a speech recognition apparatus. Furthermore, this Kana-Kanji conversion device can be used alone as a word processor, or can be used by being incorporated in various devices that require Kana-Kanji conversion. Also, it can be realized in a form incorporated in an operating system of a computer. When it is realized by being incorporated as software in a device using a computer, it can be handled in the form of a flexible disk or CD-ROM on which this software is recorded, or can be distributed through personal computer communication or the like.
[0023]
A software program (application program) for realizing the functions of these units is stored in a portable storage medium (portable storage medium) such as a floppy disk or a CD-ROM, and from the portable storage medium to the main memory of the computer system or externally. It is transferred to the storage device. A device for providing these software programs is provided via a communication line, and the software program for realizing the kana-kanji conversion method is transferred from the supply device to the main memory or external storage device of the computer system via the communication line.

Of course, in a computer capable of parallel processing, kana-kanji conversion may be performed by one application (input method), and the conversion result may be transferred to a required application. In this case, the input method collectively accepts input from the keyboard 72 or the like.
[0031]
Next, the kana-kanji conversion apparatus of this embodiment will be described with reference to FIG. This kana-kanji conversion device is realized by integrating the hardware and software in the computer 10 described above, and FIG. 1 is represented as a block diagram including the part realized by software. . This kana-kanji conversion device is centered on the control unit 170, an input unit 180 that receives input from the keyboard 72 and the two-button mouse 73 via the operating system, and a dictionary 110 stored in the hard disk 84 together with a plurality of programs related to kana-kanji conversion. A kana-kanji conversion unit 100 for generating kana-kanji mixed character string conversion candidates (hereinafter referred to as “candidates” as appropriate) by referring to a dictionary for kana character strings input by the input unit 180 and performing phrase segmentation processing, A candidate storage unit 130 for temporarily storing the conversion candidate, and searching the dictionary 110 when creating the candidate to determine whether a predetermined special character is present from the character string constituting the candidate. Candidate storage unit 130 (a type identifier is set according to the type of special character but is generally called an identifier). Special character search unit 120 to be stored, identification display instruction unit 140 for instructing special character identification display with reference to the identifier of candidate storage unit 130, special character search unit 120, and identification display instruction unit 140 are provided with search conditions and identification display conditions. A condition setting unit 150 for setting a candidate display, a candidate display creating unit 160 for creating a candidate display after identification display according to an instruction from the identification display instruction unit 140, and displaying the set candidate display, other menu display, guidance display, and the like on the color CRT 76. The display unit 190 is provided.
[0032]
Further, the kana-kanji conversion apparatus of the present embodiment has a processing means 200 that is called at the same time or after the candidate identification is displayed, and a menu display means 220 for displaying or calling the processing means.
[0033]
The kana-kanji conversion unit 100 has an input kana character buffer 102 that holds the kana character string input therein until the conversion process of the kana character string is completed. The dictionary 110 includes a kana-kanji conversion unit 100 which is referred to by the kana-kanji conversion unit 100 when a phrase is segmented, or a kana-kanji mixed character string candidate for each phrase is created, a special character dictionary 114 which is referred to by the special character search unit 120, and a kana A synonym dictionary 116 that is appropriately referred to by the kanji conversion unit 100 and the special character search unit 120 is provided. The kana-kanji conversion dictionary 112 may be configured as a single unit, or may be configured as a standard dictionary, a user dictionary, or a technical term dictionary.
[0034]
As shown in FIG. 4, the structure of the special character dictionary 114 has special characters (predetermined kanji, symbols, etc., as shown in FIG. A kana candidate and a synonym candidate for kana reading are registered.
[0035]
The special character search unit 120 is activated when a kana-kanji mixed candidate is created by the kana-kanji conversion unit 100, and searches for a special character shown in the special character dictionary 114 in the character string constituting the candidate. When the corresponding special character exists in the special character dictionary 114, the special character dictionary is searched for an appropriate synonym corresponding to the special character, which is called from the identifier search unit 122 and the synonym replacement unit 212 for searching and acquiring the corresponding type identifier. 114, a synonym search unit 126 that is acquired from 114, and a kana search unit 124 that is called from the kana character replacement unit 214 and similarly acquires kana candidates corresponding to special characters. The special character search unit 120 stores the searched identifier in the candidate storage unit 130 in association with each character of the character string candidate mixed with kana and kanji.
[0036]
When a special character is mixed with the candidate in the candidate storage unit 130, the identification display instruction unit 140 instructs the identification display and passes the candidate to the candidate display creation unit 160. The special character identification display instruction unit 142 selects a special character type identifier from a special character type identifier indicating a special character type (for example, kanji that can be used by school year, personal kanji, emergency kanji, forbidden words in company documents, and idioms). Judgment is made, and identification display according to the type is instructed. The identification display may be displayed in a separate guidance window or the like without changing the candidate display itself, or the display mode of the special character itself, for example, the color or font may be changed using the display mode change instruction unit 146. good. When the special word is composed of two characters such as “manual”, the special word display instruction unit 144 instructs the display mode change instruction unit 146 so that the two characters can be seen as one body. This is to distinguish from the case where “hand” and “motion” are selected separately.
[0037]
The menu display means 220 is activated at the same time as or after the display of the candidate including the special character identified and displayed. The identifier of the special character currently displayed is acquired from the candidate storage unit 130, and a guidance display corresponding to the type of the special character, for example, “This kanji is not a common kanji” is displayed. Further, it has a processing means start instruction unit 224 for starting the processing prepared in the processing means 200, and creates a start button for starting the processing on the menu. In this embodiment, the menu display unit 220 acquires guidance display data from the processing unit 200, and the display data of the activation button is produced in-house to create a menu screen and save it in the menu storage unit 222. This is displayed via the display unit 190.
[0038]
The processing means 200 is a collection of processes that can be executed simultaneously with or after identification display of candidates including special characters. The special character replacement unit 210 assists replacement of special characters when they are inappropriate. In this embodiment, the synonym replacement unit 212 is called from the processing unit activation instruction unit 224 and is activated. The special character currently selected is acquired, and based on this, the special character dictionary 114 is searched by the synonym search unit 126, and if there is a corresponding synonym, this is displayed in the menu. When the synonym displayed by the user is selected, the special character is replaced with the synonym and stored again in the candidate storage unit 130, and the identification display instruction unit 140 is instructed to update the display. Similarly, the kana character replacement unit 214 is called from the processing means activation instructing unit 224, searches the special character dictionary 114 by the kana search unit 124, obtains the kana character, and if an instruction from the user is given, the special character is Replace with the kana character and store again in the candidate storage unit 130. These replacement means may be called directly by selecting special characters with the mouse. The guidance display unit 202 is called from the identification display instruction unit 140 and can display guidance regarding special characters. Further, it may be called from the menu display means 220, or guidance data can be provided to other means.
[0039]
Next, the flow of special character identification display will be described with reference to FIG. When kana characters are acquired in step A1, the kana-kanji conversion unit 100 searches the kana-kanji conversion dictionary 112 in step A2, and creates one kana-kanji mixed character string candidate in step A3. Here, the special character search unit 120 is activated to search the special character dictionary 114 for each character constituting the candidate. If there is a hit character in the special character dictionary 114 in step A5, the identifier search unit 122 searches for the type identifier, associates it with the special character, stores it as one of the candidates in the candidate storage unit 130, and controls the pseudonym. Return to Kanji conversion unit 100. Of course, storage in the candidate storage unit 130 may be performed under the control of the kana-kanji conversion unit 100.
[0040]
The kana-kanji conversion unit 100 determines whether or not all the kana-kanji conversion dictionaries 112 have been searched in step A6. If not yet, the kana-kanji conversion dictionary 112 returns to step A2 and continues to search the kana-kanji conversion dictionary 112. An identification flag is attached and stored in the candidate storage unit 130. When the dictionary search is finished, in step A7, the identification display instructing unit 140 searches for the identifier of each character of the character string candidate mixed with kana and kanji stored in the candidate storage unit 130, and displays the identification display according to the identifier. Instruct. In step A8, the candidate display creation unit 160 and the display unit 190 perform special character identification display. A specific display form will be described later.
[0041]
FIG. 4 shows the structure of the special character dictionary 114. The type identifier, kana candidate, and synonym candidate are registered in the same record corresponding to the special character that becomes the heading. “It” is given a type identifier “08” indicating a personal name kanji, and “I” is registered as a kana candidate. Synonyms are not registered. The special character “manual” is a special character composed of two characters. Although not registered in the dictionary of FIG. 4, even when “hand” and “motion” are registered as special characters, longer “manual” is selected and its identifier is detected. . “Manual” is positioned as an in-house document prohibited word, and is given the type identifier “A0”. There is no kana candidate, and “manual” is registered as a synonym candidate. In this embodiment, the special character dictionary 114 has a synonym field and a synonym as a specific character string. However, the synonym field has a pointer to the independent synonym dictionary 116, and " The synonym dictionary 116 may be looked up with the heading “manual” to obtain synonyms.
[0042]
FIG. 5 shows the type identifiers corresponding to the types of special characters used in this embodiment. As special characters, type identifiers “01” to “06” are set for each grade in characters (mainly kanji) learned from the first grade to the sixth grade. Furthermore, “07” is associated with characters acquired at junior high school or higher, “08” is associated with personal kanji, and “09” is associated with emergency kanji. Although the personal name kanji is originally included in the emergency kanji, this embodiment distinguishes them by attaching different identifiers. When creating a document for elementary school students, it is preferable to display special characters other than the type identifiers “01” to “06”. In a document for third graders, kanji over 4 years are identified and displayed as unlearned characters. The in-house document prohibited word is a word that prohibits the use of one word when there are a plurality of synonyms. For example, if there are synonyms “manual” and “manual”, the in-house document is unified with “manual”, and if it is to be converted to “manual”, an identification is displayed and a warning is given.
[0043]
Similarly, an apocalypse is a word that is not normally used, and an identifier “A1” is given as a special word. In this embodiment, the type identifier A1 is controlled by the identification display instruction unit 140 so as not to display the candidates themselves. Other special words include broadcast-prohibited terms and discriminatory words. Of course, not only these but the user should set appropriately. The special character dictionary 114 of this embodiment is provided with a support program that allows the user to freely add and delete special words, type identifiers, kana candidates, and synonyms.
[0044]
FIG. 6 is a diagram illustrating the internal structure of the identification display instruction unit 140. The candidate character storage unit 132 is a part that stores kana-kanji mixed character string candidates created by the kana-kanji conversion unit 100, and the identifier storage unit 134 stores type identifiers corresponding to the candidate characters. Is set to Assuming that the candidate display shown in FIG. 11 (a) is being performed, “below” constituting “below” is “04” in 4th grade Kanji, and “below” is “01” in 1st grade Kanji. , “01” is stored in association with “Ni” as hiragana learned in the first grade of elementary school. Note that hiragana, katakana, etc. may be non-kanji characters and a type identifier such as “00” may be added. Furthermore, the type identifier may be set in detail to distinguish it from the first semester, the second semester, and the third semester of the fourth grade of elementary school. Among the characters that make up the other candidates, “Ryo” is attached to junior high school or higher, 烏 is used for emergency, and “It” is assigned a type identifier for personal kanji. Thus, since an identifier is attached to each character, identification display or replacement processing can be performed in units of characters.
[0045]
Based on these identifiers, the identification display instruction unit 140 instructs identification display. The result of the identification display is shown in FIG. In the echo line 300 which is the currently edited line, the currently selected kana-kanji mixed character string candidates are representatively displayed. In the kana-kanji conversion apparatus of the embodiment, the candidate being selected is displayed in reverse video, but in the figure, it is shown surrounded by a frame for convenience. As for the candidate “Howi”, only “Yu” is displayed in red. In the figure, it is indicated by hatching. In addition, “烏” is displayed in yellow and “band” in red. In addition, “I”, “incense”, and “猪” are identified and displayed by the set colors.
[0046]
FIG. 7 shows a special character identification display setting menu for displaying FIG. This menu is activated by the condition setting unit 150 and sets what kind of identification display is performed for the detected identifier for each module in the identification display instruction unit 140. In the menu, for the grade kanji, “junior high school” is selected with the button indicating the grade, and “above” is selected with the button indicating the condition. This applies to kanji learned at junior high school and above. The button labeled “Display” is a button for selecting whether to display candidates including special characters that meet the conditions. That is, since “how” in FIG. 11 (a) includes the kanji “yo” from junior high school or higher, the candidate “how” itself is controlled not to be displayed. In this case, the identification display instruction unit 140 deletes “how” in the candidate storage unit 130. Alternatively, the candidates in the candidate storage unit 130 may be maintained so that “how” is not included in the candidate display in the candidate display creation unit 160. In this embodiment, the school year kanji is set to “display”. In addition, when the presence / absence of color coding is selected in the color coding display item and “Yes” is selected for color coding, a color can be further selected by a color button. In the present embodiment, “red” is selected, and as a result, in FIG. 11A, “Ryo”, “bandit”, and “incense” are displayed in red as Chinese characters learned at junior high school or higher. These color-coded displays are instructed by the display mode change instruction unit 146.
[0047]
Similarly, in the special character display setting menu, the personal name Kanji “I” is displayed in blue, the emergency Kanji “烏” is displayed in yellow, and the in-house document prohibited words are displayed in shaded display. The apologetic word is selected as “Do not display”, and the candidate itself is not displayed. Although the candidates that are identified and displayed alert the user, there is still room for the user to make a forced choice, whereas the apocalypse does not display candidates from the beginning, so the selection itself is not valid. It becomes possible. It is preferable to use such a process for hateful words, discriminatory words, and the like. Further, although displayed as a candidate, it may be set such that conversion is impossible (cannot be taken in by the kana-kanji conversion unit 100).
[0048]
As the special character display setting menu, a plurality of menus having different conditions can be prepared and stored in the condition setting unit 150. If the menu can be selected according to the type of document, such as an in-house document, an external document, or a personal document, the usability is improved. A plurality of setting menus are prepared to store the condition settings so that the user can select them. When editing a document, it is possible to automatically select the condition setting by discriminating from the file name of the document file (especially the extension defined by MS-DOS), the stored directory name, and folder name. Good.
[0049]
FIG. 8 is a specific flow at the time of identification display by the identification display instruction unit 140. After all the kana-kanji mixed character string candidates are stored in the candidate storage unit 130, the identification display instruction unit 140 is called. The identification display instructing unit 140 calls candidates one by one, executes this flow for each candidate, designates each color (changes the color designation attribute corresponding to each character to a designated color), and then creates a candidate display creation unit. To 160. In step B1, the characters constituting each candidate and the corresponding type identifiers are acquired, and in step B2, first grade kanji is determined. Since the condition of grade Kanji is set to junior high school or higher in the menu of FIG. 7, it is determined from the type identifier whether it is junior high school kanji or higher. For characters determined as YES, in step B3, a special character identification display instruction section A red display is instructed by 142. Characters marked as NO are not identified.
[0050]
In step B4, it is similarly determined whether it is a personal name kanji. If so, in step B5 it is instructed to display blue, in step B6 it is determined whether it is an emergency kanji. In step B8, it is determined whether the word is an in-house document prohibited word. Examples of in-house document prohibited words are shown in the window display of FIG. This is a case where the word “manual” is registered as an in-house document prohibited word for the candidate “manual machine”. “Hand” and “movement” constituting “manual” are not in-house document prohibited words, but correspond to special characters when the word “manual” is used. Examples of such special characters set at the word level include aphrodisiacs, discriminatory words, broadcast-prohibited terms, and the like. Of course, it is possible to set an in-house document prohibited word at the one-character level. In the present embodiment, the in-house document prohibited words are displayed in a shaded manner. In addition, special characters consisting of two or more characters are surrounded by a frame or the like so that they can be seen together. Such special words composed of two or more special characters are instructed to be identified and displayed by the special word display instruction unit 144.
[0051]
In step B10, it is determined whether or not an idiom is included in the characters constituting the candidate. If any part of the characters constituting the candidate is an idiom, the identification display instructing unit 140 causes the candidate storage unit 130 to store Delete the corresponding candidate itself. This is because “not display” is set as the candidate for the apologetic word in the menu of FIG.
[0052]
The above processing is repeated for all candidates stored in the candidate storage unit 130, and after an instruction for identification display is given, a candidate display is created in the candidate display creation unit 160.
[0053]
The special character identification display has been described above. However, the present embodiment is not limited to this, and has a means for performing guidance display (description display) and a means for replacing the special character for the special character that has been identified and displayed. Yes. Hereinafter, these means will be described.
[0054]
FIG. 11 shows a state in which a menu including a guidance display is displayed after the special character is identified and displayed, and the replacement unit is activated. First, when the kana character “how” is input and kana-kanji conversion is instructed, the first candidate “below” is displayed on the echo line 300. If the conversion key is operated because it is not a desired candidate, next, as shown in (a), a candidate window 310 is displayed, and nine candidates among all candidates 60 are displayed. Note that a menu display 320 including a guidance display is displayed near a special character. The menu display 320 is desirably displayed directly beside, directly above, or directly below the special character. However, if it is difficult to display a candidate window, the range in which the correspondence with the special character that is identified and displayed can be clarified (in this application, This state is called “neighborhood”).
[0055]
When the user selects the desired candidate “how” with the mouse 73 or the like, the candidate of the echo line 300 is changed to “how”, and “how” is highlighted in the candidate window 310 by the selection cursor 312. The
[0056]
Here, since “Yo” is displayed in red, (b) shows that the user has double-clicked “Yo” with the mouse 73. In (b), a menu display 320 is displayed by the menu display means 220 of FIG. 1, and a guidance display 322 is provided inside. “Ryo” is a guide to display that kanji is learned at junior high school and above, and helps the user to judge. Similarly, guidance displays are provided for personal kanji, emergency kanji, in-house document prohibited words, and the like.
[0057]
FIG. 9 shows a flow when the guidance display is performed. When a special character is selected in step C1, the menu display unit 220 passes the special character to the guidance display unit 202. In step C2, the guidance display unit 202 acquires the type identifier corresponding to the received special character from the candidate storage unit 130. In step C 3, the guidance display unit selects guidance data corresponding to the type identifier from the various types of guidance data stored therein, and passes the guidance data to the menu display unit 220.
[0058]
Further, in step C4, the menu display unit 220 calls the synonym replacement unit 212 to determine whether there is a synonym corresponding to the special character “Yo” selected in the special character dictionary 114. Similarly, the kana character replacement unit 214 also determines whether or not there is a kana character candidate corresponding to the special character dictionary 114, receives the result, and changes the display mode of the kana character replacement unit activation button 324 and the synonym replacement unit activation button 326. Let Since the special character dictionary 114 does not have a synonym corresponding to “Yo”, an identification display indicating that the special character dictionary 114 cannot be activated is displayed in FIG. After acquiring these pieces of information, the menu display unit 220 creates a menu and stores it in the menu storage unit 222. The menu is displayed based on the menu data stored in step C5. A menu end button 328 is displayed together with a guidance display 322, a kana character replacement unit activation button 324, and a synonym replacement unit activation button 326.
[0059]
In FIG. 11B, when the kana character replacement unit activation button 324 is selected, the kana character replacement unit 214 is activated. This will be described with reference to the flowchart of FIG. When the kana character replacement unit 214 is activated in step D1, the special character to be replaced is acquired from the menu display means 220 or the candidate storage unit 130 in step D2. In step D3, the special character dictionary 114 is searched with the special character, and the corresponding kana character is acquired. Specifically, the kana character replacement unit 214 searches the special character dictionary 114 using “Y” as a key by the kana search unit 124 to acquire “I” and “Nyo” which are kana character candidates. In step d4, a kana character candidate selection button 342 indicating “I” and a kana character candidate selection button 344 indicating “Nyo” are displayed in the kana character candidate window 340, and the kana character candidate selection button 342 is selected with the mouse cursor 346. In step d5, the target special character is replaced with the selected kana character and stored again in the candidate storage unit 130. When the candidate display is updated in step D6, “Y” is replaced with “I” as shown in FIG. At the same time, in step 7, the kana character candidate window 340 is closed. “What” can be selected in the same manner as other candidates. The menu display can be ended by a menu end button 328.
[0060]
Such a function that can be converted into kana characters is extremely useful when creating a document for each grade. Conversion to “Monday” and correction to “Monday” can be easily performed during the kana-kanji conversion operation.
[0061]
The kana character replacement unit 214 includes a candidate learning unit (not shown). According to this candidate learning unit, when “Iiani” is created as a candidate, the candidate is learned and registered in the kana-kanji conversion dictionary 112 or the like. From this candidate onward, “how” and “what” are displayed in parallel as candidates, and the user's selection operation can be made easier. This learning function can be turned ON / OFF.
[0062]
Next, the operation of replacing special characters with synonyms will be described. Since the operation is almost the same as the kana character replacement, the description by the flow chart is omitted. In FIG. 12A, the kana / kanji conversion unit 100 searches for the kana / kanji conversion dictionary 112 and outputs “leading machine” and “manual machine” as candidates. Shows the situation where “manual machine” is selected. Since “manual” is registered as an in-house document prohibited word as described above, it is displayed in a shaded manner.
[0063]
Here, when “manual” is double-clicked with the mouse 73, a menu display 360 shown in FIG. The guidance display 362 displays a guidance corresponding to the in-house document prohibited word ““ Manual ”is an inappropriate expression in the in-house document.” As in the case of kana character replacement, the guidance display means displays “manual” from the candidate storage unit 130. ”Is obtained, and guidance data corresponding to the type identifier is transferred to the menu display means 220. When the synonym replacement unit activation button 326 is selected, a synonym candidate window 380 is displayed, and a synonym selection button 382 indicating “manual” is displayed. When the selection is made with the mouse cursor 346, the candidate is replaced from “manual machine” to “manual machine” and displayed on the echo line 300 and the candidate window 310 as shown in FIG. Internally, the synonym replacement unit 212 is activated by the processing unit activation instructing unit 224, the “manual” character is acquired from the menu display unit 220 or the candidate storage unit 130, and the special character dictionary 114 is acquired by the synonym retrieval unit 126. Is searched and the replacement character “manual” is retrieved.
[0064]
The replacement function described above is also very useful for processing special characters at the Kana-Kanji conversion device level. Special characters are registered as “manual”, so not only “manual machine” but also “manual operation”, “manual transmission” and other candidates are identified and displayed as “manual operation” “manual operation” Replacement candidates such as “transmission” can be created.
[0065]
Similarly to the kana character replacement unit 214, the synonym replacement unit 212 includes a candidate learning unit (not shown), and automatically registers candidates created by the replacement in the kana-kanji conversion dictionary 112 and the like. It can be displayed as a candidate for the conversion unit 100.
[0066]
The synonym replacement unit 212 searches for synonyms registered in the special character dictionary 114, but the special character dictionary 114 has only a pointer indicating another dictionary, for example, the synonym dictionary 116. A synonym may be searched from the synonym dictionary 116 by tracing the pointer.
[0067]
FIG. 13 is a diagram showing details of display of a special character composed of a plurality of characters. Special characters consisting of a plurality of characters are surrounded by a frame and displayed so as to be seen as one body. Of course, other display methods may be used as long as they can be determined as one.
[0068]
As mentioned above, although one Example of the kana-kanji conversion measure of this invention has been described, other embodiments are possible. The flowchart of FIG. 14 shows another aspect of the overall flow described in FIG. In FIG. 3, the special character search unit 120 is activated every time the kana-kanji conversion unit 100 creates a character string candidate mixed with kana-kanji characters. However, in FIG. 14, the special character search unit 120 is activated after all candidates are stored in the candidate storage unit 130. The character search unit 120 is activated.
[0069]
In step E1, a kana character string is acquired from the input unit 180. In step E2, the kana-kanji conversion unit 100 searches the kana-kanji conversion dictionary 112. In step E3, a kana-kanji mixed character string candidate is created and stored in the candidate storage unit 130. . In step E4, this is repeated until the end of the search for the kana-kanji conversion dictionary 112, and all candidates are stored in the candidate storage unit 130. In step E5, the special character dictionary 114 is searched for each character constituting each candidate. In step E6, the identifier of the character whose search is hit is obtained, and stored in the candidate storage unit 130 in association with the character. At step E7, the identification display instruction unit 140 instructs identification display according to the identifier, and at step E8, special character identification display is performed.
[0070]
The advantage of the method of FIG. 14 is that it can operate without being aware of the special character search unit 120 until the kana-kanji conversion unit 100 stores candidates in the candidate storage unit 130. That is, the kana-kanji conversion unit 100 can use a conventional one as it is and add a special character identification display function. Compared with the case where the special character search unit 120 is called every time a candidate is created, the processing is simpler and the development period can be shortened.
[0071]
FIG. 15 is a further improvement of the function of the kana character replacement unit 214 described in FIG. When the kana character replacement unit 214 is called from the menu display unit 220, a special character to be dealt with is acquired from the candidate storage unit (or the menu display unit 220) in step F1, and the kana search unit 124 is activated in step F2 to activate the special character. The dictionary 114 is searched to obtain a corresponding kana candidate. In step F3, the input kana character is obtained from the input kana character buffer 102. In the "How to" example, get "How".
[0072]
In step F4, the kana characters “I” and “Nyo” acquired from the special character dictionary 114 are compared with the input kana characters “Ikuni”. Then, the kana candidate “I” partially matching “how” is selected as valid.
[0073]
Since the number of kana candidates has been narrowed down to one, in step F5, the kana character candidate window 340 of FIG. 11 is not displayed, and the target special character “I” is replaced with the selected kana character “I”, and the candidate storage unit Store again. In step F6, the candidate display of the echo line 300 and the candidate window 310 is updated to “what”, and the menu display 320 is closed in step F7.
[0074]
In this way, the kana candidates to be replaced are automatically narrowed down compared with the input kana characters, so that the user is not burdened with selecting a kana candidate.
[0075]
FIG. 16 shows another aspect of the operation screen of the condition setting unit 150 of the present embodiment. The usable kanji display window 400 displays kanji types that are not designated for identification display by the identification display instruction unit 140 and kanji characters that are specifically registered, assuming that the kanji is usable. The types of kanji are grouped for each unit like 402 and displayed in a tree (called a folder) so that they can be recognized intuitively. The kanji that can be acquired in the 1st and 2nd semesters of elementary school 1st grade, 2nd grade, and 3rd grade are classified into usable kanji. Click on the 3rd grade elementary school folder with the mouse 73 for the semester. A folder showing is displayed. Furthermore, when the elementary school third grade 2 semester folder is clicked, a kanji list 404 is displayed, and the kanji registered in the elementary school third grade 2 semester folder can be specifically viewed.
[0076]
In the unusable kanji display window 410, emergency kanji including common kanji and personal name kanji acquired after the third semester of elementary school are registered and displayed. The figure shows a state in which a kanji list 414 registered by clicking a folder in the third grade of the third grade is displayed.
[0077]
In this state, kanji can be moved in units of folders displayed as a tree. For example, the elementary school 3rd and 3rd semester folder can be moved from the unusable kanji display window 410 to the usable kanji display window 400. Specifically, drag the 412 tree folder in the 3rd and 3rd grade with the mouse (move the mouse while holding down the mouse button) and drop it at the location of the 3rd grade folder in the 402 tree (click the mouse button). Release). Then, a third semester folder is added under the third grade elementary school folder in the tree 402. By this operation, “drinking”, “institution”, “luck”, and “swimming” are all registered as usable kanji. Furthermore, it is possible to move in higher folder units. In addition, if the information amount of the type identifier is increased, it is possible to identify and display kanji units. In this case, if the tool of FIG. 16 is used, it can be easily moved to kanji units.
[0078]
In such a visual user interface, the condition setting unit 150 sets identification display kanji (in FIG. 16, emergency kanji including common kanji and personal name kanji for the third and third grades of elementary school). The condition setting unit 150 sets the identification display instructing unit 140 to perform identification display when detecting a kanji having an identifier indicating an emergency kanji including a common kanji of third grade and third semester and a personal name kanji. It is.
[0079]
The present kana-kanji conversion device can have other modes. In the embodiment, the condition setting unit 150 sets the identification display method for each type of identifier in the identification display instruction unit 140, but sets the condition in the identifier search unit 122 and sets “not display”. It is also possible to perform control so that an aphoric word or the like is not stored in the candidate storage unit 130 by determining a candidate including a special character “not displayed” when the candidate is received from the kana-kanji conversion unit 100. Furthermore, the condition setting unit 150 can set the name of the dictionary to be searched, the position, and the search level (when registered in a hierarchy with special characters, replacement characters, etc.) for the special character search unit 120. It is.
[0080]
In the embodiment, the identifier is temporarily stored in the candidate storage unit 130. However, the special character search unit 120 can search the special character dictionary 114 when the identification display instruction unit 140 calls the candidate from the candidate storage unit 130. In this case, the capacity of the buffer used as the candidate storage unit 130 can be reduced.
[0081]
In this embodiment, the special character and the corresponding identifier are entered in the special character dictionary 114. However, it is possible to attach the identifier to a candidate such as an independent word registered in the kana-kanji conversion dictionary 112. In this case, the character string candidates mixed with kana and kanji cannot be identified and displayed in units of one character as in the above-described embodiment. However, the processing means 200, special character replacement means 210, and menu display means 220 in the embodiment can be used in the same manner, and the same effect can be accepted. There is also an advantage that the special character dictionary 114 does not need to be newly provided.
[0082]
In the above-described embodiment, the operation using the mouse 73 has been mainly described. However, the same operation can be performed using other input means such as the keyboard 72.
