Description

  The present invention relates to a Kana-Kanji conversion device for Japanese input. In particular, the present invention relates to a kana-kanji conversion device, method, program, and personal computer that reduce the burden of re-input of the same sentence.

Conventionally, for sentences (phrases) that are often used by individuals, once Kana-Kanji conversion is performed, the desired sentence is created, and the same sentence is entered again at another opportunity, the reading is entered from the beginning. However, it is necessary to perform Kana-Kanji conversion (including correction of the conversion result), and there is a problem that the longer the sentence, the greater the burden on the user.
In other words, in order to obtain the conversion result of a sentence such as “Today is sunny”, you must enter all the readings such as “Kyohare is.” When you want to get the same candidate again, the same sentence All readings of must be re-entered.

In order to avoid this, it is also possible for the user to register a sentence in the dictionary and search for conversion candidates by inputting the first character of the reading of the registered sentence.
That is, in the above example, for the input of one character “ki” at the beginning of the reading of the registered sentence, “today is sunny” is searched in the dictionary as a candidate starting from the inputted “ki”. .
However, as sentences registered in the dictionary are accumulated, there are a large number of conversion candidate sentences when searching for conversion candidates by inputting the first character of the reading of the sentence, and further, short sentences, long sentences, and frequency of use are increased. There is a problem that a low sentence and a high sentence are mixed and the operability for selecting a desired sentence from the searched conversion candidates is deteriorated.

There are the following conventional techniques related to such problems.
Conventionally, for the purpose of providing a word processor having a high conversion speed in which a word can be selected before inputting all readings, when a conversion confirmation is instructed from a reading input means for inputting a word reading and a conversion instruction confirmation means , The word dictionary used to store the word, the reading and the frequency of occurrence, and when three or more readings are input from the reading input means, the word dictionary is used to perform a forward matching search, Some have a configuration including feed forward candidate selection means for selecting five candidates from the highest (see, for example, Patent Document 1).

  However, in Patent Document 1, when the same sentence is created again, input can be shortened for a part that can be a word, and normal input is required for other parts. As the sentences registered in the dictionary accumulate, the number of conversion candidate sentences increases when searching for conversion candidates by inputting the first character of the reading of the sentence, and further, short sentences, long sentences, and usage It does not solve the problem that the operability of selecting a desired sentence from the retrieved conversion candidate sentences is deteriorated due to a mixture of sentences with low frequency and high sentences.

  Conventionally, in order to perform kana-kanji conversion with good conversion candidate selection operability and high efficiency, a means for displaying one or more conversion candidates corresponding to the input kana, and one of the one or more conversion candidates And a means for further displaying one or more conversion candidates associated with the selected conversion candidate when the conversion candidate is selected and the expansion key is pressed (see, for example, Patent Document 2).

  However, in the above-mentioned patent document 2, after inputting the reading of the head of the sentence, the same sentence is created again by pressing the phrase expansion key many times. As described above, the sentence registered in the dictionary is accumulated. As a result, when searching for conversion candidates by inputting the first character of the reading of the sentence, there are many conversion candidate sentences, and short sentences, long sentences, low-use sentences, and high sentences are intermingled and searched. This does not solve the problem that the operability of selecting a desired sentence from the conversion candidate sentences is deteriorated.

JP 05-233600 A JP 2005-050141 A

  Therefore, in the present invention, in consideration of the above-mentioned problems, as sentences registered in the dictionary are accumulated, there are a large number of conversion candidate sentences when searching for conversion candidates by inputting the first character of the reading of the sentence. Furthermore, Kana-Kanji conversion device, method, program, and personal computer that can improve the operability of selecting a desired sentence from the retrieved conversion candidate sentences by mixing short sentences, long sentences, low-use sentences, and high sentences. The purpose is to do.

In order to solve the above problems, the present invention provides a kana-kanji conversion apparatus that simply converts a repeated reading of a sentence into kanji-kana mixed sentences and displays the converted conversion candidates. a character holding portion, and the valid period storage unit storing valid period, and Do kanji conversion dictionary section or converts the reading of the sentence in kanji and kana, and displays the converted kanji and kana in the kana-kanji conversion dictionary section A sentence dictionary part that stores the kanji-kana mixed sentence reading, the number of characters read in the kanji-kana mixed sentence, the date of use in which the kanji-kana mixed sentence was used, and the kana-kanji conversion dictionary part If the number of characters read in the converted kanji-kana mixed sentence is greater than or equal to the number of effective reading characters held in the effective reading character number holding unit, the converted kanji-kana mixed sentence is valid. The sentence dictionary registering part to be registered in the sentence dictionary part and the sentence dictionary part are searched for the input of the first character of the sentence reading, and the number of characters read in the kanji-kana-mixed sentence of the searched conversion candidate is The number of days from the date of use of the kanji-kana mixed sentence as the conversion candidate to the current date is stored in the effective period holding unit. A dictionary search unit for validating a kanji-kana mixed sentence of a conversion candidate searched when it is within the valid period and displaying it on the kana-kanji conversion dictionary unit, and a user designation for the valid reading character number holding unit A setting change unit that changes or returns the effective reading character number by value, changes the effective period by a user-specified value to the effective period holding unit, or returns to the change, and the dictionary search unit, The effective number of reading characters held in the effective reading number holding unit is determined to be changed or returned to the change, the effective period held in the effective period holding unit is determined to be changed or changed, and the change or change is determined. When there is a return, the conversion candidate is searched using the number of effective reading characters that have been changed or returned to the change and the effective period, and the searched conversion candidate is displayed in the Kana-Kanji conversion dictionary unit. Providing equipment.

Further, the dictionary search unit searches the sentence dictionary unit, and when the searched conversion candidate kanji-kana mixed sentence is valid, it is held in the sentence dictionary unit via the character dictionary registration unit. The used date is updated on the searched date.
In addition, a dictionary deletion unit is provided, and the dictionary deletion unit mixes kanji kana as conversion candidates by changing the number of effective reading characters of the effective reading character number holding unit by the setting changing unit and changing the effective period of the effective period holding unit. The number of reading characters of the sentence is less than the number of effective reading characters held in the effective reading number holding unit, and the number of days from the date of use of the kanji-kana mixed sentence as the conversion candidate to the current date searched retains the effective period If there is a kanji-kana mixed sentence held in the sentence dictionary part that is outside the valid period held in the part and is no longer subject to search by the dictionary search part, the corresponding kanji-kana mixed sentence is indicated by an instruction. Is deleted.

In the Kana-Kanji conversion method, which can easily convert repeated readings into Kanji-Kana mixed sentences and display the converted conversion candidates, a process of maintaining the number of effective reading characters for Kanji-Kana mixed sentences and the effective for Kanji-Kana mixed sentences a step of holding period, and a step of registering a reading of the sentence as if the number of characters read the converted kanji and kana is enabled to read the number of characters or held is valid the converted kanji and kana, statements When a kana-kana mixed sentence converted from the reading of a kanji is registered , the kana-kana mixed sentence reading, the kana-kana mixed sentence reading number, and the kanji-kana mixed sentence are used together with the converted kanji-kana mixed sentence. The process of holding the date of use and the input of the first character of the reading of the sentence is searched for a kanji-kana-mixed sentence converted from the reading of the held sentence, From the retrieved conversion candidate kanji / kana mixed sentence number of readings to the number of valid reading characters or more, and from the use date of the searched conversion candidate kanji / kana mixed sentence to the current date searched number of days as valid kanji and kana search conversion candidates in the case of the validity period is held, and change the step that displays the valid reading characters is held at the specified value of the user or the The process of changing the effective period retained by the user's specified value or changing the setting to return to the change, and whether there is a change in the number of effective reading characters held or whether there is a setting change to return to the change If there is a setting change to be changed or returned to the change, it is changed or changed. Effective reading characters made the back against searches the conversion candidate by using the validity period, provides a kana-kanji conversion method characterized by comprising the step of displaying conversion candidates retrieved in the kana-kanji conversion dictionary section.

A program that easily converts repeated readings into kanji-kana mixed sentences, displays the converted conversion candidates, and executes a kana-kanji conversion on a computer. a step of holding the valid period for the kana, register the readings of the sentence as if the number of characters read the converted kanji and kana is enabled to read the number of characters or held is valid the converted kanji and kana If a kanji-kana mixed sentence that has been converted to a reading procedure and a kanji kana mixed sentence is registered, the kanji kana mixed sentence converted to the kanji kana mixed sentence, the kana kana mixed sentence reading number, kanji kana kana Converts the reading of the stored sentence to the procedure to retain the date of use in which the mixed sentence was used and the input of the first character of the reading of the sentence. Kanji-kana-mixed sentences are searched, and the number of readings of the kanji-kana-mixed sentence of the searched conversion candidate is equal to or greater than the number of valid reading characters, and the date of use of the kanji-kana-mixed sentence of the searched conversion candidate and enable the kanji and kana search conversion candidates when the number of days before the current date retrieved is within the valid period that is held from the holding and instructions on the display, the specified value of the user Change or return the effective number of effective reading characters, change the effective period held by the user's specified value, or change the setting to return to the change, and the number of effective reading characters Judgment whether there is a setting change to be changed or returned to the change, and to determine whether there is a change in the validity period being held or to return the setting to be changed, and to return to the change or change If there is a further, characterized in that it comprises a step of displaying a change or an effective reading characters made the return to changes, retrieves the conversion candidates by using the validity period, conversion candidates retrieved on the kana-kanji conversion dictionary section A program that executes kana-kanji conversion on a computer is provided.

In a personal computer that performs kana-kanji conversion by simply converting repeated readings into kanji-kana mixed sentences and displaying converted conversion candidates, it holds an effective reading number holding unit that holds the number of effective reading characters and a valid period a valid period holding unit for, converts the reading of the sentence in kanji and kana, and Do kanji conversion dictionary unit or to display the converted kanji and kana, along with the converted kanji and kana in the kana-kanji conversion dictionary section, Reading of kanji-kana mixed sentences, number of characters read in kanji-kana mixed sentences, sentence dictionary part holding the date of use in which kanji-kana mixed sentences are used, and reading of kanji-kana mixed sentences converted by the kana-kanji conversion dictionary part If the number of characters is equal to or greater than the number of valid reading characters held in the valid reading character number holding unit, the converted kanji-kana mixed sentence is considered to be valid. The sentence dictionary registering part to be registered in the dictionary part and the sentence dictionary part are searched with respect to the input of the first character of the sentence reading, and the number of characters read in the kanji-kana mixed sentence of the searched conversion candidate is the number of effective reading characters The number of valid reading characters held in the holding unit, and the number of days from the date of use of the kanji-kana mixed sentence as the conversion candidate to the current date searched is valid A dictionary search unit for validating a kanji-kana mixed sentence as a conversion candidate searched when it is within the period and displaying it on the kana-kanji conversion dictionary unit, and valid for a user-specified value for the effective reading character number holding unit A setting change unit that changes or returns the number of reading characters to the effective period holding unit and changes or returns the effective period with a user-specified value to the effective period holding unit, and the dictionary search unit includes the effective reading The number of effective reading characters held in the character number holding unit is determined to be changed or returned to the change, the validity period held in the effective period holding unit is determined to be changed or returned to the change, and the change or change is returned. Personality performing kana-kanji conversion, characterized in that conversion candidates are searched using the number of effective reading characters that have been changed or returned to the change and the effective period, and the searched conversion candidates are displayed in the kana-kanji conversion dictionary unit Provide a computer.

As described above, according to the present invention, the number of effective reading characters for kanji-kana mixed sentences is held, the effective period for kanji-kana mixed sentences is held, the number of held effective reading characters is changed, and held. Change the validity period, convert the reading of the sentence to kanji-kana mixed sentence, display the converted kanji-kana mixed sentence, and convert the reading of the sentence to the number of effective readings that is stored In some cases, the converted kanji / kana mixed sentence is judged to be valid, and when the kanji / kana mixed sentence converted from the reading of the sentence is determined to be valid, along with the kanji / kana mixed sentence converted from the sentence reading, The reading of kanji-kana mixed sentences, the number of characters read in kanji-kana mixed sentences, the date of use in which the kanji-kana mixed sentences were used, and the stored sentences for the first character input of the sentence reading Search for a kanji-kana mixed sentence that has been converted to a reading, and use a kanji-kana mixed sentence that is greater than the number of valid reading characters that is stored in the kanji-kana mixed sentence that is found as a conversion candidate. The kanji-kana-mixed sentence of the conversion candidate that was searched is enabled and displayed when the number of days from the date to the current date is within the valid period that is retained. For sentence input, register relatively long kanji / kana mixed sentences, narrow down the kanji / kana mixed sentences to be registered, and input the first (first) reading of kanji / kana mixed sentences. After searching for kanji-kana mixed sentences, you can create kanji-kana mixed sentences simply by selecting conversion candidates for the searched kanji-kana mixed sentences. And Turkey to reduce the burden of force is possible.

The setting changing unit can be activated many times by the user, and can be restored even if the settings of the valid reading character number holding unit and the valid period holding unit are changed once.
Also, by updating the date of use, conversion candidates for kanji-kana mixed sentences that are used infrequently are deceived, conversion candidates that are used frequently survive, and conversion candidates that are displayed and selected can be narrowed down. It becomes possible.
In addition, it is possible to prevent generation of useless storage areas by deleting short kanji-kana mixed sentences that are held less frequently.

  The Kana-Kanji conversion device according to the present invention is used in a personal computer as an example, and is composed of a CPU (Central Processing Unit), a memory, etc., and a user inputs Japanese readings to convert them into Kanji-Kana mixed sentences and repeatedly used. The conversion result of kanji-kana mixed sentences to be stored can be stored in sentence units, and the next input can be easily converted to kanji-kana mixed sentences desired by the user with a small number of input characters, and the conversion result of kanji-kana mixed sentences can be created. It is controlled by a computer program.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a kana-kanji conversion apparatus according to the present invention. As shown in the figure, the kana-kanji conversion device 100 includes a reading input unit 101, a conversion control unit 102, a dictionary search unit 103, a kana-kanji conversion dictionary unit 104, a sentence dictionary registration unit 105, a sentence dictionary unit 106, a display unit 107, a conversion The candidate operation unit 108, the setting change unit 109, the valid reading character number holding unit 110, and the valid period holding unit 111 are configured.

Here, the reading input unit 101 has a function of inputting a reading of a Japanese sentence by a user input operation, and inputting the first character of the reading of the sentence (first) in order to obtain a conversion result.
The conversion control unit 102 performs integrated control of each unit such as transfer of reading input of a sentence from the reading input unit 101, start of conversion, transfer of conversion candidates, and instruction to register a conversion result sentence.
The dictionary search unit 103 includes a selection unit 103A and a determination unit 103B. Upon receiving an instruction to read a sentence and start conversion from the conversion control unit 102, the selection unit 103A selects either the kana-kanji conversion dictionary unit 104 or the sentence dictionary unit 106. When Kana-Kanji conversion dictionary unit 104 is selected, conversion candidates in Kana-Kanji conversion dictionary unit 104 are output to conversion control unit 102. When sentence dictionary unit 106 is selected, the number of effective reading characters is retained. Referring to section 110 and validity period holding section 111, determination section 103B determines whether conversion candidates are valid. In the case of validity determination, conversion candidates for kanji-kana mixed sentence conversion sentences from sentence dictionary section 106 are sent to conversion control section 102. The data is output and displayed on the display unit 107 for user selection.

Here, the selection unit 103A selects the kana-kanji conversion dictionary unit 104 for normal kana-kanji conversion, and selects the sentence dictionary unit 106 for the input of the first character of the sentence reading. Details of the determination unit 103B will be described later.
The kana-kanji conversion dictionary unit 104 is a dictionary in which words are registered in advance for normal kana-kanji conversion. The kana-kanji conversion dictionary unit 104 outputs conversion candidates in response to the search from the dictionary search unit 103 and is used to create a kanji-kana mixed sentence.

The sentence dictionary registration unit 105 includes a determination unit 105A. Upon receiving a kanji-kana mixed sentence decision candidate and a registration instruction from the conversion control unit 102, the determination unit 105A refers to the valid reading character number holding unit 110 to determine whether or not registration is performed. The sentence candidate is registered in the sentence dictionary unit 106 as a kanji-kana mixed sentence.
The sentence dictionary unit 106 is a dictionary in which the sentence dictionary registration unit 105 registers sentence readings, kanji-kana mixed sentences as conversion candidates, the number of reading characters (N (positive integer)), and the date of use. The conversion candidate of the kanji-kana mixed sentence corresponding to the search by the first character of the reading of the sentence input from the section 103 is output.

The display unit 107 displays a reading of a sentence input from the reading input unit 101, a kanji-kana mixed sentence before registration, and conversion candidates for a kanji-kana mixed sentence.
The conversion candidate operation unit 108 instructs the user to start conversion with respect to the input reading, and instructs the kana-kanji conversion dictionary unit 104 and the sentence dictionary unit 106 to change the conversion candidate next candidate, to determine the conversion candidate. .

The effective reading character number holding unit 110 is connected to the dictionary search unit 103 and the sentence dictionary registration unit 105, holds the effective reading character number N0 that enables reading of the input sentence, and holds the effective reading character number N0 (positive integer). Are output to the dictionary search unit 103 and the sentence dictionary registration unit 105.
The effective reading character number N0 is used for processing in the sentence dictionary registration unit 105 and the dictionary search unit 103 as described later.

The validity period holding unit 111 is connected to the dictionary search unit 103, holds the validity period M0 (positive integer) from the date of use that makes the conversion candidate valid, and stores the held validity period M0 in the dictionary search unit 103. Output.
The valid period M0 is used for processing in the dictionary search unit 103 as described later.
The setting changing unit 109 is connected to the effective reading character number holding unit 110 and the effective period holding unit 111, and sets and changes the effective reading character number N0 held in the effective reading character number holding unit 110 according to a change instruction from the user. The effective period M0 held in the effective period holding unit 111 is set and changed.

FIG. 2 is a diagram for explaining an example of holding and searching in the sentence dictionary unit 106 in FIG. As shown in the figure, the sentence dictionary unit 106 is provided with a sentence reading field, a kanji kana mixed sentence field as a conversion candidate, a sentence reading character number (N) field, and a use date field.
It is assumed that the effective reading character number holding unit 110 holds the effective reading character number N0 = 5, and the conversion candidate of the kana-kana mixed sentence determined from the conversion control unit 102 to the sentence dictionary registration unit 105 “Yesterday / ha / snow / ga / When the message “gets off” is entered, the determination unit 105A obtains the number of characters N = 13 for the conversion candidate reading “Kino / ha / Yuki / ga / pretend / was” for the kanji-mixed sentence that has been confirmed, and the effective reading Compared with the number of characters N0 = 5, N> N0, and since the number of characters N of the confirmed kanji-kana mixed sentence conversion candidate is larger than the number of valid reading characters N0, the determined kanji-kana mixed sentence conversion candidate is determined to be valid, A conversion candidate for the confirmed kanji-kana mixed sentence is registered in the sentence dictionary unit 106.
In this case, in the sentence dictionary unit 106, “Kinou / ha / yuki / ga / pretend / was” in the sentence reading column, and “Yesterday / ha / snow / in” in the kanji mixed sentence column of the conversion candidate. / 13. ”,“ 13 ”in the number of reading characters (N) column of the sentence, and the usage date in which the kanji mixed sentence of conversion candidate is used in the usage date column is March 4, 2005 In this case, it is held as “2005050304”.

In this way, it is possible to register a long sentence of a confirmed conversion candidate having a valid reading character number N0 = 5 or more, and it is impossible to register a short sentence of a confirmed conversion candidate having a valid reading character number N0 = 5 or less. As a result, the registered sentences are narrowed down, so that the operability for selecting a desired sentence is improved.
“/” Represents a word break and is not included in the number of reading characters. Since the other examples in FIG. 2 are the same, description thereof is omitted. The same applies hereinafter.

Furthermore, it is assumed that the validity period holding unit 111 holds the validity period M = 3 (days). When inputting a sentence on March 5, 2005, an input of a sentence “It snowed yesterday” was entered. When performing, when the user inputs the first character “ki” of the reading of the sentence with the reading input unit 101 and instructs the conversion candidate operation unit 108 to convert the input, the selection unit of the dictionary search unit 103 select a sentence dictionary portion 106 at 103A, as shown in FIG. 2, searches for conversion candidates of kanji and kana beginning from the input at sentence dictionary portion 106 "ki".

  When the determination unit 103B of the dictionary search unit 103 determines that the number of reading characters N is equal to or more than the number of effective reading characters N0 = 5 held in the effective reading character number holding unit 110 with respect to the conversion candidate of the searched kanji mixed sentence, If the dictionary search unit 103 determines that the number of days from the date of use to the current date searched for is within the valid period M0 held in the valid period holding unit 111, the dictionary search unit 103 converts the kanji-kana mixed sentence. If it is retrieved as a candidate, “Yesterday snow has fallen” is output to the conversion control unit 102 and displayed on the display unit 107.

  FIG. 3 is a flowchart illustrating an example of a series of operations of the entire kana-kanji conversion apparatus 100 in FIG. In step 201, the conversion control unit 102 passes the reading input from the reading input unit 101 to the dictionary search unit 103. When the selection unit 103A of the dictionary search unit 103 selects conversion from the sentence dictionary unit 106 for the input of the first character of the reading of the sentence based on the input of reading, the process proceeds to step 210.

In step 202, the conversion control unit 102 causes the kanji conversion dictionary unit 104 to perform normal kana-kanji conversion on the input of the sentence reading, and creates a kanji-kana mixed sentence conversion candidate.
In step 203, the conversion control unit 102 causes the display unit 107 to display conversion candidates for kanji-kana mixed sentences.

In step 204, the conversion control unit 102 determines whether or not the conversion candidate operation unit 108 needs to correct conversion candidates for mixed kana-kana sentences.
In step 205, if correction is necessary, the process returns to step 202, and the above process is repeated until the conversion candidate for the kanji-kana mixed sentence is correct.
In step 206, if correction is not required, conversion candidates for kanji-kana mixed sentences are determined.

  In step 207, when the sentence dictionary registration unit 105 receives the conversion candidate for the kanji / kana mixed sentence confirmed from the conversion control unit 102, the determination unit 105 </ b> A determines the number N of characters to be read in the conversion candidate for the confirmed kanji / kana mixed sentence. It is determined whether the number of effective reading characters held in the effective reading character number holding unit 110 is greater than or less than N0. If the number of valid reading characters is less than N0, the process ends. As a result, it becomes impossible to register conversion candidates for short kanji-kana mixed sentences.

In step 208, if the number of valid reading characters is N0 or more, the sentence dictionary registration unit 105 determines whether or not a conversion candidate for a confirmed kanji-kana mixed sentence conversion is registered. If it is determined that the registration has been completed, the process ends.
If it is determined in step 209 that the sentence is not registered, the conversion candidate for the kanji / kana mixed sentence confirmed in the sentence dictionary unit 106 is registered, and the process ends.

In step 210, the dictionary search unit 103 searches for conversion candidates of kanji / kana mixed sentences corresponding to the first character of the reading of the sentence input to the sentence dictionary unit 106.
In step 211, the determination unit 103B of the dictionary search unit 103 determines whether the number N of characters read in the kanji-kana mixed sentence of the searched conversion candidate is greater than or less than the number of effective reading characters N0 held in the number of effective reading characters holding unit 110. I do. If the number of effective reading characters is less than N0, the process returns to step 210 and the search is performed again.

In step 212, if the number of effective reading characters is N0 or more, the effective period holding unit 111 holds the number M of days from the date of use of the conversion candidate of the searched kanji-kana mixed sentence to the current date searched. It is determined whether it is within the valid period M0. If it is out of the valid period, the process returns to step 210 to search again for conversion candidates for kanji-kana mixed sentences.
In step 213, if it is within the valid period, it is determined whether or not the end of the sentence dictionary unit 106 has been searched. If the search has not been completed up to the end, the process returns to step 210, and the search for conversion candidates for kanji-kana mixed sentences is continued.

In step 214, when the search is performed up to the end of the sentence dictionary unit 106, the dictionary search unit 103 causes the conversion control unit 102 to display the converted kanji / kana mixed sentence conversion candidates on the display unit 107.
In step 215, the user determines whether or not there is a conversion candidate for the target kanji / kana mixed sentence with respect to the conversion candidate for the kanji / kana mixed sentence displayed on the display unit 107 as the conversion candidate for the searched kanji / kana mixed sentence. If there is no conversion candidate for the target kanji mixed sentence, the process proceeds to step 218.

In step 216, if there is a conversion candidate for the target kanji-kana mixed sentence, the user selects and confirms the corresponding kanji-kana mixed sentence conversion candidate.
In step 217, the conversion control unit 102 changes the use date of the conversion candidate of the selected kanji-kana mixed sentence to the sentence dictionary registration unit 105, as described later, and changes the processing date to the date of input. Exit.

In step 218, if there is no corresponding kanji-kana mixed sentence conversion candidate, the conversion candidate operation unit 108 performs a cancel process, returns to the initial input state, and ends the process.
Therefore, according to the present invention, regarding the input of a sentence to be used repeatedly, a relatively long kanji-kana mixed sentence is registered, the kanji-kana mixed sentence to be registered is narrowed down, and the first (first) reading of the kanji-kana mixed sentence is registered. After searching for long kanji / kana-mixed sentences that are relatively frequent in character input, you can create kanji-kana-mixed sentences only by selecting conversion candidates for the searched kanji / kana-mixed sentences. It is possible to improve the input operation and reduce the burden of re-inputting the same sentence.

FIG. 4 is a flowchart for explaining an operation example in which the setting change unit 109 changes the settings of the valid reading character number holding unit 110 and the valid period holding unit 111. In step 301, the setting change unit 109 determines whether or not the number of valid reading characters N0 has been changed by the user. If the number of valid reading characters N0 is not changed, the process proceeds to step 303.
In step 302, if there is a change in the number of effective reading characters N0, the number of effective reading characters N0 is changed with a user-specified value.

In step 303, it is determined whether or not the effective period M0 has been changed by the user. If there is no change in the valid period M0, the process is terminated.
In step 304, if there is a change in the validity period M0, the validity period is changed with the value specified by the user, and the process ends.
As an example, search for a search example when the number of effective reading characters N0 is changed from “5” to “8” and the effective period M0 is changed from “3 (day) ” to “7 (day) ”. The following description will be made assuming that the current input date is March 4, 2005.

  FIG. 5 is a diagram for explaining a display example of conversion candidates for kanji / kana mixed sentences when the setting of the number of valid reading characters N0 and the valid period M0 is changed. As shown in (a) of this figure (1), in the example held in the sentence dictionary unit 106 shown in FIG. 2, there are four conversion candidates for kanji-kana mixed sentences starting with “ki”. Due to the restriction of the number of reading characters N0 = 8, “Who are you?” Is not displayed on the display unit 107 as shown in FIG.

Similarly, as shown in (a) of FIG. 2 (2), there are three conversion candidates for kanji / kana mixed sentences starting with “wa”, but due to the limitation of the validity period M0 = 7 (day) , As shown in (b) of FIG. (2), “I will buy a cake of strawberries” is not displayed on the display unit 107.
As shown in FIG. 3 (3), when there is no conversion candidate for the corresponding kanji-kana mixed sentence, the conversion candidate operation unit 108 performs cancel processing as described above (see step 218 in FIG. 3). Return to the initial input state “ki”.

  In this way, the setting change unit 109 can be activated many times by the user, and can be restored even if the settings of the valid reading character number holding unit 110 and the valid period holding unit 111 are changed once.

  FIG. 6 is a diagram illustrating an example of the sentence dictionary unit 106 in which the use date is changed. This figure (a) shows the example of the sentence dictionary part 106 before use date change, and this figure (b) shows the example of the sentence dictionary part 106 after use date change. The conversion candidate operation unit 108 selects the conversion candidate “Today is sunny” with respect to the display of the conversion candidate display unit 107 of the kanji-kana mixed sentence starting with “ki” input on March 4, 2005. When confirmed, the sentence dictionary registration unit 105 inputs the use date of February 27, 2005, which is the use date of the corresponding conversion candidate, as shown in FIG. The date is updated on March 4, 2005.

  In this way, by updating the date of use, conversion candidates for kanji-kana mixed sentences with low usage frequency are deceived, and conversion candidates with high usage frequency survive, narrowing down conversion candidates to be displayed and selected. It becomes possible.

Next, when the setting change unit 109 changes the setting of the valid reading character number holding unit 110 or the valid period holding unit 111, there is a sentence dictionary unit 106 that does not become a conversion candidate for a kanji-kana mixed sentence. Accordingly, a useless storage area is generated in the sentence dictionary unit 106. An example of preventing the generation of this useless storage area will be described below.
FIG. 7 is a block diagram showing a schematic configuration of a kana-kanji conversion apparatus 100 according to the present invention, which is a modification of FIG. As shown in this figure, compared with FIG. 1, a dictionary deletion unit 112 is provided, and the dictionary deletion unit 112, according to a user instruction, has a number of effective reading characters N0 and an effective period held in the number of effective reading characters holding unit 110. A conversion candidate for a kanji / kana mixed sentence that does not satisfy the validity period M0 held in the holding unit 111 is deleted from the sentence dictionary unit 106.

  FIG. 8 is a flowchart for explaining an operation example of the dictionary deletion unit 112 in FIG. As shown in the figure, in step 305, the dictionary deletion unit 112 refers to the valid reading character number holding unit 110, and the number of reading characters of the conversion candidate of one kanji / kana mixed sentence registered in the sentence dictionary unit 106 is valid. It is determined whether or not the number of reading characters is less than N0. If the number of effective reading characters is less than N0, the process proceeds to step 307.

In step 306, if the number of valid reading characters is N0 or more, the dictionary deleting unit 112 refers to the valid period holding unit 111, and the number of days from the date of use to the current date retrieved is outside the valid period M0. It is determined whether or not. If it is within the valid period M0, the process proceeds to step 308.
In step 307, the dictionary deletion unit 112 deletes the corresponding kanji-kana mixed sentence conversion candidate from the sentence dictionary unit 106.

In step 308, the dictionary deletion unit 112 determines whether the conversion candidate for the kanji / kana mixed sentence is the end of the sentence dictionary unit 106. If not, the process proceeds to step 305, and the next kanji / kana mixed sentence conversion candidate is determined. It is determined whether or not the above process should be repeatedly deleted. If it is the end, the process ends.
FIG. 9 is a diagram illustrating an example of the sentence dictionary unit 106 from which conversion candidates are deleted. This figure (a) shows the example of the sentence dictionary part 106 before deletion, and this figure (b) shows the example of the sentence dictionary part 106 after deletion. Assuming that the number of effective reading characters held in the effective reading number holding unit 110 is N0 = 7, the reading character number N of the kanji-kana mixed sentence change candidate “who are you?” In the sentence dictionary unit 106 shown in FIG. 5 ”and the number of valid reading characters N0 is less than 7. Therefore, as shown in FIG. 5B, the dictionary deletion unit 112 deletes the conversion candidate“ who are you? ”In the sentence dictionary unit 106.

  In this case, the dictionary deletion unit 112 does not automatically delete, but is supplementarily provided with a function of deleting according to a user instruction. As described above, since the setting change unit 109 can be activated any number of times by the user, the setting of the valid reading character number holding unit 110 or the valid period holding unit 111 is once changed and may be restored.

  In the above description, the Kanji conversion device can be used for a personal computer, but is not limited to this, and can also be used for a mobile phone.

It is a block diagram which shows schematic structure of the Chinese character converter based on this invention. It is a figure explaining the example of holding | maintenance and search of the sentence dictionary part 106 in FIG. 2 is a flowchart illustrating an example of a series of operations of the entire kana-kanji conversion apparatus 100 in FIG. 1. 10 is a flowchart for explaining an operation example of changing the settings of the valid reading character number holding unit 110 and the valid period holding unit 111 by the setting change unit 109. It is a figure explaining the example of a display of the conversion candidate at the time of setting change of the number of effective reading characters N0 and the effective period M0. It is a figure explaining the example of the sentence dictionary part 106 which changed the use date. It is a modification of FIG. 1, and is a block diagram showing a schematic configuration of a Kana-Kanji conversion device 100 according to the present invention. It is a flowchart explaining the operation example of the dictionary deletion part 112 in FIG. It is a figure which shows the example of the sentence dictionary part 106 which deleted the conversion candidate.
