[0029]
[First Embodiment]
First, a first embodiment of an electronic dictionary to which the present invention is applied will be described.
[0030]
FIG. 2 is a block diagram illustrating an example of a functional configuration of the electronic dictionary 1 according to the first embodiment. As shown in the figure, the electronic dictionary 1 is configured to include each functional unit of a CPU 100, an input device 200, a display device 300, a RAM 400, and a flash ROM 500.
[0031]
The CPU 100 executes processing based on a predetermined program in accordance with an input instruction, performs an instruction to each functional unit, data transfer, and the like, and controls the electronic dictionary 1 in an integrated manner. Specifically, the CPU 100 reads a program stored in the flash ROM 500 in response to a press signal or the like input from the input device 200, and executes processing according to the program. Then, the processing result is stored in the RAM 400 and a display signal for displaying the processing result is appropriately output to the display device 300 to display the corresponding display information.
[0032]
The input device 200 includes a key group necessary for inputting characters such as kana and alphabets and selecting a function, and outputs a pressed key pressing signal to the CPU 100. This input device 200 corresponds to the key group 20 shown in FIG. 1 and implements input means such as specifying a dictionary type, inputting input characters, instructing display of explanation information, and instructing change of search rules.
[0033]
The display device 300 displays various screens based on display signals input from the CPU 100, and is configured by an LCD or the like. The display device 300 corresponds to the display 10 shown in FIG.
[0034]
The RAM 400 includes a memory area that temporarily holds various programs executed by the CPU 100 and data related to the execution of these programs. In particular, in order to realize the first embodiment, a search word storage area 402 and a headword candidate list storage area 404 are provided.
[0035]
The flash ROM 500 stores initial programs for performing various initial settings, hardware inspections, loading of necessary programs, and the like. The CPU 100 sets the operating environment of the electronic dictionary 1 by executing this initial program when the electronic dictionary 1 is powered on.
[0036]
The flash ROM 500 stores various processing programs related to the operation of the electronic dictionary 1 and programs and data for realizing various functions provided in the electronic dictionary 1. In particular, to implement the first embodiment, an English-Japanese dictionary DB 502, a first dictionary search program 504, and an ambiguous search rule table 506 are stored. The first dictionary search program 504 includes a first spell check search program 504a and a first search rule change program 504b.
[0037]
The CPU 100 executes the first dictionary search process according to the first dictionary search program 504 stored in the flash ROM 500. For example, in response to the pressing operation of the English-Japanese dictionary key 35b, the CPU 100 first determines the dictionary DB to be searched as the English-Japanese dictionary DB 502. Subsequently, in response to the input operation of the input character, the CPU 100 reads the headword that matches the input character and the explanation information corresponding to the headword from the English-Japanese dictionary DB 502 and displays it.
[0038]
FIG. 3 shows an example of the storage format of the English-Japanese dictionary DB 502. As shown in the figure, dictionary data (information) in which headwords and explanation information are associated is accumulated (set) in an English-Japanese dictionary DB 502, which is one set information. In the explanation information, explanation information which is character data for explaining the corresponding headword is stored.
[0039]
When the English-Japanese dictionary key 35b is pressed and the spell check search method is designated, the CPU 100 executes the first spell check search process in accordance with the first spell check search program 504a, and the input character Search for a headword having a partial difference with (hereinafter referred to as “headword candidate”).
[0040]
Specifically, when the spell check search method is selected and the translation / decision key 25 is pressed, the CPU 100 first sets an input character as a search word. At this time, the search term is held in the search term storage area 402. FIG. 4 shows an example of the search term storage area 402. In the search word storage area 402 shown in the figure, a search word “anderstand” is stored.
[0041]
Next, the CPU 100 refers to the fuzzy search rule table 506 and reads the found word character number range and the error-permitted character number corresponding to the number of characters of the search word. FIG. 5 shows an example of the fuzzy search rule table 506. As shown in the figure, the fuzzy search rule table 506 includes a set value of a headword character number range indicating an allowable range of the number of headword characters in association with the number of search word characters, a search word and a headword. And a setting value of the number of erroneously permitted characters indicating the allowable range of the number of different characters.
[0042]
For example, as shown in FIG. 4, when “andstand” with the number of search word characters “10” is set as the search word, the CPU 100 sets the range of the number of found word characters “9” corresponding to the number of search word characters “10”. ˜12 ”and the number of erroneously permitted characters“ 3 ”are read out. Then, the CPU 100 performs an ambiguous search process to find headwords with the number of characters “9” to “12” among the headwords included in the English-Japanese dictionary DB 502 with the number of erroneous characters “3” or less. Search for a word.
[0043]
Specifically, the CPU 100 compares the character string of the search word and the character string of the search target head word (target head word) by comparing each of the upper and lower comparisons and the fuzzy comparison, and thereby finds the head word candidate. Fuzzy search. 6A and 6B are explanatory diagrams for explaining the fuzzy search process. FIG. 6A shows a comparison method based on vertical comparison, and FIG. 6B shows a comparison method based on fuzzy comparison.
[0044]
First, a comparison method by vertical comparison will be described. When comparing the character string of the target headword and the character string of the search word side by side with each other, the CPU 100 counts the number of errors when the characters located above and below are different. For example, as shown in FIG. 6A, the number of errors in the target headword “Andersen” that is counted when the target headword “Andersen” and the search word “andersstand” are compared by up-down comparison is “ 2 ".
[0045]
The CPU 100 writes the target headword whose number of errors counted by the above-described vertical comparison is equal to or less than the number of allowable characters in the headword candidate list storage area 404. FIG. 7A shows an example of a headword candidate stored in the headword candidate list storage area 404 at this stage. In the entry word candidate list storage area 404 shown in FIG. 5A, entry words candidates searched by the up-and-down comparison based on the search word “andstandand” are stored.
[0046]
Next, a comparison method by fuzzy comparison will be described. When the character string of the target headword and the character string of the search word are arranged one above the other, the CPU 100 sets the target headword character (headword target character) and the search word character (search word) in a vertical relationship. When the headword target character is different from the search word target character, “1” is added to the number of errors. Next, the CPU 100 determines whether or not the search target character to be compared is shifted by one character. That is, the CPU 100 temporarily shifts the search word target character to the immediately following character, and compares the headword target character with the shifted search word target character. If they are the same, the CPU 100 determines to shift the search word target character and keeps it as it is. If different, the CPU 100 restores the search word target character as it is not shifted.
[0047]
For example, as shown in FIG. 6B, the number of errors counted when the target headword “ampersand” and the search word “andstandstand” are compared by fuzzy comparison is “3”. The specific processing procedure is as follows. For example, the CPU 100 compares the headword target character “p” indicated by the arrow Y10 with the search word target character “d” in the vertical relationship, and determines that they are different, and adds “1” to the number of errors. Subsequently, the CPU 100 determines whether or not to shift the search word target character to be compared by one character. In other words, the CPU 100 temporarily shifts the search term target character “d” to the immediately following character “e”, and compares the headword target character “p” with the shifted search term target character “e”. Then, the search target character is returned to its original state without shifting. Further, the CPU 100 compares the headword target character “a” indicated by the arrow Y20 with the search term target character “t” in the vertical relationship, and determines that they are different, and adds “1” to the number of errors. Subsequently, the CPU 100 determines whether or not to shift the search word target character to be compared by one character. In other words, the CPU 100 temporarily shifts the search word target character “t” to the immediately following character “a” and compares the search word target character “a” with the shifted search word target character “a” and determines that they are the same. Then, it is determined that the search target character is shifted, and this is left as it is.
[0048]
The CPU 100 adds the target headword whose number of errors counted by the fuzzy comparison is equal to or less than the number of permitted characters to be written to the headword candidate list storage area 404 and writes it. FIG. 7B shows an example of the entry word candidate list stored in the entry word candidate list storage area 404 at this stage. In the headword candidate list storage area 404 shown in FIG. 6B, in addition to the headword candidate shown in FIG. 5A, as shown in records L10 and L12, the search word “anderstand” is added. The headword candidate searched by the fuzzy search processing based on this is stored.
[0049]
Then, the CPU 100 displays a list of headword candidates stored in the headword candidate list storage area 404 as a result of the fuzzy search processing described above, and ends the first spell check search processing. At this time, for example, the CPU 100 rearranges the found word candidates stored in the found word candidate list storage area 404 in alphabetical order and displays the list.
[0050]
In addition, when the search rule change key 32 is pressed after displaying a list of candidate words searched by the first spell check search process described above, the CPU 100 shifts to the search rule change mode, and the first The first search rule change process is executed according to the search rule change program 504b.
[0051]
Specifically, the CPU 100 first displays a search rule change screen that displays the set values set in the search rule table 506 that are ambiguous at the time, and changes the set values of the entry word number range and the number of allowed mistake characters. Accept the operation. Then, the CPU 100 updates the fuzzy search rule table 506 according to the change operation.
[0052]
Then, when the ambiguous search rule table 506 is updated by the first search rule change process described above, the CPU 100 executes the first spell check search process again, and finds the found words stored in the found word candidate list storage area 404. List word candidates.
[0053]
Next, the operation of the electronic dictionary 1 will be described with reference to FIGS. 8, 10, and 11 show the processing flow of the CPU 100, and FIG. 9 shows a transition example of the screen displayed on the display device 300.
[0054]
FIG. 8 is a processing flow of the CPU 100 related to the first dictionary search process realized by executing the first dictionary search program 504. In response to the pressing operation of the English-Japanese dictionary key 35b (step a10: YES), the CPU 100 displays a list of English-Japanese dictionary search methods (step a20), accepts a search method selection operation (step a30), and inputs characters. Is accepted (step a40).
[0055]
FIG. 9A shows an example of an input character input screen W10 displayed on the display device 300 by pressing the English-Japanese dictionary key 35b. On this input character input screen W10, a search method “English-Japanese”, a search method “spell check”, a search method “single phrase search”, and a search method “example sentence search” corresponding to the normal search method can be selected. In the figure, the search method “spell check” is highlighted and displayed as a search method selection marker M10. The user can select another search method by moving the search method marker M10 up and down by pressing the direction instruction key 27.
[0056]
When the translation / decision key 25 is pressed on the input character input screen W10 shown in FIG. 9A (step a50: YES), and the selected search method is the spell check search method (step a60). : YES), CPU 100 executes the first spell check search process (step a70).
[0057]
FIG. 10 is a processing flow of the CPU 100 related to the first spell check search process realized by executing the first spell check search program 504a. As shown in the figure, the CPU 100 first executes a fuzzy search process to search for a headword candidate (step b10). At this time, the searched entry word candidate is stored in the entry word candidate list storage area 404. Next, the CPU 100 displays a list of headword candidates searched by the fuzzy search process (step b20), and ends this process.
[0058]
For example, in the input character input screen W10 shown in FIG. 9A, when the character input key 23 is operated to input “andstand” as the input character I10 and the translation / decision key 25 is pressed, As shown, a candidate word list display screen W12 displaying a candidate word list T10 searched based on the input character “anderstand” is displayed. In the headword candidate list T10, the topmost headword candidate “Andersen” is highlighted and displayed as the selection marker M12.
[0059]
Returning to FIG. 8, after executing the first spell check search process described above, the CPU 100 accepts an operation of selecting a headword displayed as a list of headword candidates in step b20 shown in FIG. 10 (step a80). At this time, in response to the pressing operation of the search rule change key 32 (step a90: YES), the CPU 100 shifts to the search rule change mode and executes the first search rule change process (step a100).
[0060]
FIG. 11 is a processing flow of the CPU 100 related to the first search rule change process realized by executing the first search rule change program 504b. As shown in the figure, the CPU 100 first displays a search rule change screen displaying the set values set in the search rule table 506 that is ambiguous at the time (step c10).
[0061]
When the shift key 37 is pressed on the search rule change screen (step c20: YES), the CPU 100 switches between the cursor movement mode and the setting change mode by the upper instruction key 27c and the lower instruction key 27d (step c30). Specifically, the CPU 100 switches to the setting change mode when the pressing mode of the upper instruction key 27c and the lower instruction key 27d set at that time is the cursor movement mode, and moves the cursor when the setting mode is the setting change mode. Switch to mode.
[0062]
In addition, when the direction instruction key 27 is pressed on the search rule change screen (step c40: YES), the pressing mode of the upper instruction key 27c and the lower instruction key 27d set at that time is the cursor movement mode. In this case (step c50: YES), the CPU 100 moves the cursor position in accordance with the pressed direction instruction key 27 (step c60).
[0063]
Further, when the pressing mode of the upper instruction key 27c and the lower instruction key 27d is not the cursor movement mode, that is, in the setting change mode (step c50: NO), the pressed direction instruction key 27 is the upper instruction key 27c. Alternatively, in the case of the down instruction key 27d (step c70: YES), the CPU 100 changes the value of the cursor position (step c80) and updates the corresponding set value in the fuzzy search rule table 506 (step c90). Specifically, the CPU 100 adds “1” to the value of the cursor position when the up instruction key 27c is pressed, and “1” from the value of the cursor position when the down instruction key 27d is pressed. And the corresponding set value in the fuzzy search rule table 506 is updated.
[0064]
Furthermore, when the return key 33 is pressed on the search rule change screen (step c100: YES), the CPU 100 cancels the search rule change mode and ends this processing.
[0065]
FIG. 9C shows an example of a search rule change screen W14 displayed on the display device 300 when the search rule change key 32 is pressed. As shown in FIG. 5C, on the candidate word list display screen W12, each of the found word character number range and the number of allowed mistake characters set for each number of searched word characters in the search rule table 506 at that time. The search rule change screen W14 displaying the set value is displayed, and the cursor C10 is displayed at the lower limit value “9” of the found word character number range corresponding to the search word character number “10” of the search word “andstand”. On this search rule change screen W14, by pressing the direction instruction key 27 and moving the cursor C10, it is possible to designate the setting values for the entry word number range and the number of error-permitted characters. Further, after the shift key 37 is pressed to switch the pressing mode of the upper instruction key 27c or the lower instruction key 27d to the setting change mode, the setting designated by the cursor C10 is performed by pressing the upper instruction key 27c or the lower instruction key 27d. The value can be changed.
[0066]
For example, on the search rule change screen W14 shown in FIG. 9C, by operating the right instruction key 27b, the cursor C10 is moved to the position of the error permitted character number “3” corresponding to the search word character number “10”. Further, the shift key 37 is pressed to set the pressing mode of the upper instruction key 27c and the lower instruction key 27d to the setting change mode, and the lower instruction key 27d is pressed once. As a result, as shown in FIG. 9D, the value of the number of erroneous permitted characters corresponding to the number of search word characters “10” is changed to “2”. In accordance with this change operation, the corresponding setting value in the fuzzy search rule table 506 is updated to “2”.
[0067]
Returning to FIG. 8, the CPU 100 executes the first search rule change process described above, and then returns to step a <b> 70 to execute the first spell check search process again.
[0068]
For example, when the translation / decision key 25 is pressed on the search rule change screen W14 shown in FIG. 9D, the candidate words searched again based on the input character “andstand” as shown in FIG. Is displayed as a list of candidate words list display screen W16. On the candidate word list display screen W16, the candidate word “understand” is highlighted and displayed as a selection marker M14.
[0069]
As described above, once the headword candidates are displayed based on the input characters (FIG. 9B), the number of mistaken permitted characters is changed, and as shown in FIG. Word candidates can be further narrowed down.
[0070]
In addition, when the translation / decision key 25 is pressed on the candidate word list display screen W16 shown in FIG. 9E (step a110: YES), the CPU 100 determines the observation selected in the candidate word list. The explanation information corresponding to the utterance is read from the English-Japanese dictionary DB 502 and displayed (step a120), and this process is terminated.
[0071]
As described above, according to the first embodiment, based on an input character, a candidate word having a partial difference with the input character is retrieved from the English-Japanese dictionary DB 502 by the search method “spell check”. After performing a search and performing a control to display a list of searched word candidates, an operation of changing each setting value of the word count range and the number of allowed mistake characters set in the fuzzy search rule table 506 is accepted. it can. Then, according to the change operation, the fuzzy search rule table 506 can be updated, and the headword candidate can be searched again from the English-Japanese dictionary DB 502 with reference to the updated fuzzy search rule table 506. According to this, since it is possible to immediately change the setting value of the range of the number of found words and the number of allowed characters according to the found find word candidates, the searched find word candidates can be further narrowed down or searched. It is possible to search the candidate words again by expanding the range, and to easily search the desired candidate words, so that the usability of the electronic dictionary 1 can be improved.
[0072]
[Second Embodiment]
Next, a second embodiment of the electronic dictionary to which the present invention is applied will be described. The configuration of the electronic dictionary in the second embodiment is the same as that of the electronic dictionary 1 shown in FIG. 2 in the first embodiment. The RAM 400 is shown in the RAM 410 shown in FIG. 12A, and the flash ROM 500 is shown in FIG. The flash ROM 510 shown in FIG. 12B is the same as the replaced structure, and the same components are denoted by the same reference numerals and description thereof is omitted.
[0073]
As shown in FIG. 12 (a), the RAM 410 realizes the second embodiment, in particular, a search word storage area 402, a valid replacement character storage area 413, a conversion word storage area 415, and a search rule. A type storage area 417 and a headword candidate list storage area 419 are provided. Further, as shown in FIG. 5B, the flash ROM 510 stores, in particular, an English-Japanese dictionary DB 502, a second dictionary search program 514, and search rule information 516 in order to realize the second embodiment. Is done. The second dictionary search program 514 includes a second spell check search program 514a and a second search rule change program 514b. The search rule information 516 includes a character replacement rule table 516a and an ambiguous search rule table 506.
[0074]
The CPU 100 executes the second dictionary search process according to the second dictionary search program 514 stored in the flash ROM 510. Specifically, as in the first embodiment, the CPU 100 first determines the dictionary DB to be searched as the English-Japanese dictionary DB 502 in accordance with the pressing operation of the English-Japanese dictionary key 35b. Subsequently, in response to the input operation of the input character, the CPU 100 reads the headword that matches the input character and the explanation information corresponding to the headword from the English-Japanese dictionary DB 502 and displays it. Although not shown, the English-Japanese dictionary DB 502 stores dictionary data in which headwords and explanation information are associated with each other as in the English-Japanese dictionary DB 502 shown in FIG. 3 in the first embodiment.
[0075]
If the English-Japanese dictionary key 35b is pressed and the spell check search method is designated, the CPU 100 executes the second spell check search process according to the second spell check search program 514a.
[0076]
Specifically, when the spell check search method is selected and the translation / decision key 25 is pressed, the CPU 100 first sets the input character as a search word and updates the search word storage area 402. Next, the CPU 100 searches for a headword candidate for each search item of (1) conversion word search and (2) fuzzy search based on the set search word.
[0077]
(1) Conversion word search
First, the conversion word search processing executed in the search item “conversion word search” will be described by taking as an example the case where the search word “donut” is stored in the search word storage area 402. First, the CPU 100 refers to the character replacement rule table 516a and sets an effective replacement character for each target character.
[0078]
FIG. 13 shows an example of the character replacement rule table 516a in the second embodiment. As shown in the figure, the character replacement rule table 516a includes a fixed replacement character set in advance in association with each target character of the alphabet “a” to “z” and an invalid replacement that is user setting data. Characters and additional replacement characters are set. For example, as shown in the record L20, replacement characters “e”, “h”, “i”, “o” are set for the target character “a”, and replacement characters “h” are set as user setting data. "Is set as an invalid replacement character, and alphabet" c "is set as an additional replacement character.
[0079]
The CPU 100 refers to the character replacement rule table 516a, deletes the invalid replacement character from the replacement character, adds an additional replacement character to the replacement character, and sets the effective replacement character of each target character. Store in the storage area 413. At this time, the CPU 100 sets the user setting flag of the additional replacement character in the user setting data among the effective replacement characters to “ON”.
[0080]
FIG. 14 shows an example of the effective replacement character storage area 413. As shown in the figure, the effective replacement character storage area 413 stores effective replacement characters associated with user setting flags for each target character of alphabets “a” to “z”. For example, as shown in the record L30, the effective replacement characters “e”, “i”, “o”, “c” are stored in the target character “a”, and the user setting corresponding to the additional replacement character “c” is set. The flag is set to “ON”.
[0081]
Subsequently, the CPU 100 refers to the valid replacement character storage area 413 and generates a conversion word based on the character string of the search word stored in the search word storage area 402. At this time, the generated conversion word is stored in the conversion word storage area 415 in association with the priority display flag.
[0082]
FIG. 15 shows an example of the conversion word storage area 415. In the conversion word storage area 415 shown in the figure, conversion words obtained by replacing each character constituting the search word “dunut” with a valid replacement character are stored, and the user setting flag “ON” corresponds to the effective replacement character storage area 413. “ON” is set in the priority display flag of the conversion word generated based on the attached valid replacement character.
[0083]
For example, the effective replacement characters of the target character “u” shown in the record L32 in FIG. 14 are “e” and “ugh”, and the characters constituting the search word “donut” as shown in the records L40 and L42 in FIG. The CPU 100 generates a conversion word “donut” in which the character “u” immediately after “o” is replaced with the effective replacement character “e” and a conversion word “doughnut” in which the effective replacement character “ugh” is replaced with each other and stores the conversion word. It is written in area 415. In addition, the priority display flag corresponding to the conversion word “doughnut” (record L42) generated based on the valid replacement character “ugh” associated with the user setting flag “ON” in the valid replacement character storage area 413 is “ON”. Set to
[0084]
The CPU 100 searches the English-Japanese dictionary DB 502 for headwords that match the conversion words stored in the conversion word storage area 415. When a matching headword is searched, the CPU 100 associates the headwords with the corresponding search words. It is stored in the candidate word list storage area 419 in association with the priority display flag.
[0085]
FIG. 16A shows an example of a headword candidate stored in the headword candidate list storage area 419 at this stage. In the headword candidate list storage area 419 shown in FIG. 5A, a headword candidate “doughnut” searched by the conversion word search process based on the search word “dunut” is stored. The headword candidate “doughnut” is stored in association with the priority display flag “ON” of the conversion word “doughnut” shown in the record L42 in FIG.
[0086]
(2) Fuzzy search
Next, the fuzzy search process executed by the search item “fuzzy search” will be described. This fuzzy search process is the same as the fuzzy search process described in the first embodiment. As in the first embodiment, the CPU 100 refers to the ambiguous search rule table 506 (not shown) in which the headword character number range and the error-permitted character number are set in association with the number of search word characters. A fuzzy word candidate is searched by comparing the character string and the character string of the search target word (target head word) by the comparison methods of top and bottom comparison and fuzzy comparison, and the searched word candidate Is associated with the priority display flag “OFF” and written to the candidate word list storage area 419.
[0087]
FIG. 16B shows an example of a headword candidate stored in the headword candidate list storage area 419 at this stage. In the headword candidate list storage area 419 shown in FIG. 5B, in addition to the headword candidate shown in FIG. 5A, the search is performed by the fuzzy search process based on the search word “donut”. A headword candidate is stored.
[0088]
Then, the CPU 100 displays a list of headword candidates that are searched for in each of the search items of (1) conversion word search and (2) fuzzy search and stored in the headword candidate list storage area 419. End the spell check search process. When displaying the list of headword candidates, the CPU 100 starts from the headword candidates whose priority display flag is set to “ON” among the headword candidates stored in the headword candidate list storage area 419. Control is performed so that the headword candidates are rearranged so as to be displayed in order. Further, the CPU 100 performs control to distinguish and display from other parts by displaying a part different from the character string of the search word in bold characters in the candidate word candidate character string. Note that the display form of the part different from the input character is not limited to this, and any display form that can be distinguished from other parts, such as underline display or changing the background color, may be used.
[0089]
If the search rule change key 32 is pressed after displaying the list of candidate words searched by the second spell check search process described above, the CPU 100 shifts to the search rule change mode, and the second The second search rule change process is executed according to the search rule change program 514b.
[0090]
Specifically, the CPU 100 first initializes the search rule type with “change replacement rule” and updates the search rule type storage area 417. FIG. 17 shows an example of the search rule type storage area 417. A search rule type “change replacement rule” is stored in the search rule type storage area 417 shown in FIG.
[0091]
Subsequently, the CPU 100 displays a replacement rule change screen displaying the effective replacement characters set in the character replacement rule table 516a, and accepts an operation for changing the effective replacement characters. Then, the CPU 100 updates the character replacement rule table 516a and the effective replacement character storage area 413 according to the change operation.
[0092]
For example, when the character input key 23 is pressed on the replacement rule change screen, a character string (pressed character) corresponding to the pressed character input key 23 is added to the additional replacement character of the user setting data to replace the character. The rule table 516a and the effective replacement character storage area 413 are updated.
[0093]
Further, the CPU 100 updates the search rule type storage area 417 by switching the search rule type “change replacement rule” and “change ambiguous search rule” in response to the pressing operation of the search rule change key 32. When the search rule type is switched to “change ambiguous search rule” in response to the pressing operation of the search rule change key 32, the ambiguous rule change that displays the set value set in the search rule table 506 at that time is displayed. A screen is displayed, and a change operation of each setting value of the entry word number range and the number of allowed mistake characters is accepted. Then, the CPU 100 updates the fuzzy search rule table 506 according to the change operation.
[0094]
Then, when the character replacement rule table 516a and the effective replacement character storage area 413 or the fuzzy search rule table 506 is updated by the second search rule change process, the CPU 100 executes the second spell check search process again. A list of headword candidates stored in the headword candidate list storage area 419 is displayed.
