The information processing apparatus 1 includes an input history holding unit 2, a correction information holding unit 3, a determination unit 4, and a correction candidate extraction unit 5.

  An input error that occurs when an input operation is performed multiple times consecutively does not occur when an input operation is performed only once, but occurs due to an operation error that occurs when an input operation is performed multiple times in succession. There is a case. For example, if an extra key is input between a specific key and a specific key, the input of a specific key is missing, the input order of a specific key is switched, or the input of a specific key is different There are cases where the key is entered. The information processing apparatus 1 assists correction of an input error that occurs when an input operation is performed continuously a plurality of times.

  The input history holding unit 2 holds an input history 6 of input operations. The input operation here includes input such as a character key, a BackSpace key (hereinafter referred to as BS), a Delete key (hereinafter referred to as DEL), an Enter key, a Space key, selection by a cursor, touch operation by a touch panel, and the like. For example, the input history 10 indicates that BS is input after “ABC” is input.

  The correction information holding unit 3 holds correction information 7 including past correction processes. The correction information 7 is information in which a history of past corrections is accumulated. The correction information 7 is information based on an input history with correction. The correction information 7 is accumulated when input with correction is performed. The information processing apparatus 1 can grasp how the input history before correction is corrected by the correction information 7. The correction information 7 may include template data set in advance. For example, the template data is information regarding input mistakes that are easily caused by input operators in common.

  The determination unit 4 determines whether to correct the input history 6 from the input history 6. When the determination unit 4 detects a specific input operation from the input history 6, the determination unit 4 determines to correct (correct). For example, when the correction operation is detected from the input history 6, the determination unit 4 determines that the correction is correct. The correction operation includes operations such as deletion, insertion, and rearrangement. For example, the correction operation includes DEL, BS, cursor movement, and other operations related to correction. The correction operation is not limited to this. It is also possible to set a predetermined key as a correction operation key in advance.

The correction candidate extraction unit 5 extracts the correction candidate 8 of the input history 6 based on the input history 6 and the correction information 7 when the correction is determined to be correct.
For example, the input history holding unit 2 holds “A, B, C, BS” as the input history 10. The correction information holding unit 3 holds correction information 11. The determination unit 4 detects “BS” and determines that the correction of the input history 10 is correct. The correction candidate extraction unit 5 identifies correction information “A, B, C, BS, BS, C, D, E” including the input history 10 in part from the correction information 11. The correction candidate extraction unit 5 extracts “ACDE” as a correction candidate based on the specified correction information “A, B, C, BS, BS, C, D, E”.

  The above is the first embodiment. According to such an information processing apparatus 1, when it is determined whether or not the input history 6 is to be corrected from the input history 6 and the correction is determined to be correct, the input history 6 and the correction information 7 including past correction processes are used. The correction candidate 8 of the input history 6 is extracted. That is, the information processing apparatus 1 can extract the correction candidate 8 reflecting the past correction. As a result, the information processing apparatus 1 can improve the user's input operation by presenting the correction candidate 8 that is likely to be intended by the user.

The command history is stored below. The command character string input first is a regular command that has been transmitted to the server device 31 in a series of input processes.

  The input history holding unit 43 holds the input history of the input operation in units of one command character string, but is not limited to this. For example, the input history holding unit 43 may hold the input history of input operations in units of a plurality of command character strings.

  The correction determination unit 44 determines whether it is time to present correction candidates for the command character string being input. The correction determination unit 44 determines that it is time to present correction candidates when an input error is detected. The correction determination unit 44 determines that there is an input error in the command character string being input when the reception unit 41 receives a correction operation (DEL, BS, cursor movement, and other operations related to correction), and presents correction candidates. It is determined that it is time to perform. The correction determination unit 44 determines that there is an input error in the command character string being input and presents correction candidates when there is no regular command that partially includes the command character string being input. Is determined. In addition, the correction determination unit 44 determines that there is an input error in the command character string being input when all of the regular commands including part of the command character string being input cannot be used in relation to the command history, It is determined that it is time to present a correction candidate.

Next, the hardware configuration of the client device 32 will be described. FIG. 4 is a diagram illustrating a hardware configuration of the client device according to the second embodiment.
The entire client device 32 is controlled by the processor 61. A RAM (Random Access Memory) 62 and a plurality of peripheral devices are connected to the processor 61 via a bus 69. The processor 61 may be a multiprocessor. The processor 61 is, for example, a central processing unit (CPU), a micro processing unit (MPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), or a programmable logic device (PLD). The processor 61 may be a combination of two or more elements among CPU, MPU, DSP, ASIC, and PLD.

  The RAM 62 is used as a main storage device of the client device 32. The RAM 62 temporarily stores at least part of an OS (Operating System) program and application programs to be executed by the processor 61. The RAM 62 stores various data necessary for processing by the processor 61.

  Peripheral devices connected to the bus 69 include an HDD (Hard Disk Drive) 63, a graphic processing device 64, an input interface 65, an optical drive device 66, a device connection interface 67, and a network interface 68.

  The HDD 63 magnetically writes and reads data to and from the built-in disk. The HDD 63 is used as an auxiliary storage device for the client device 32. The HDD 63 stores an OS program, application programs, and various data. Note that a semiconductor storage device such as a flash memory can also be used as the auxiliary storage device.

  A monitor 71 is connected to the graphic processing device 64. The graphic processing device 64 displays an image on the screen of the monitor 71 in accordance with a command from the processor 61. Examples of the monitor 71 include a display device using a CRT (Cathode Ray Tube) and a liquid crystal display device.

  A keyboard 72 and a mouse 73 are connected to the input interface 65. The input interface 65 transmits a signal sent from the keyboard 72 or the mouse 73 to the processor 61. The mouse 73 is an example of a pointing device, and other pointing devices can be used. Examples of other pointing devices include a touch panel, a tablet, a touch pad, and a trackball.

  The optical drive device 66 reads data recorded on the optical disk 74 using laser light or the like. The optical disc 74 is a portable recording medium on which data is recorded so that it can be read by reflection of light. The optical disc 74 includes a DVD (Digital Versatile Disc), a DVD-RAM, a CD-ROM (Compact Disc Read Only Memory), a CD-R (Recordable) / RW (ReWritable), and the like.

  The device connection interface 67 is a communication interface for connecting peripheral devices to the client device 32. For example, the device connection interface 67 can be connected to a memory device 75 or a memory reader / writer 76. The memory device 75 is a recording medium equipped with a communication function with the device connection interface 67. The memory reader / writer 76 is a device that writes data to the memory card 77 or reads data from the memory card 77. The memory card 77 is a card type recording medium.

  The network interface 68 is connected to the network 33. The network interface 68 transmits and receives data to and from other computers or communication devices via the network 33.

  With the hardware configuration described above, the processing functions of the second embodiment can be realized. The information processing apparatus 1 shown in the first embodiment and the server apparatus 31 shown in the second embodiment can also be realized by the same hardware configuration as that of the client apparatus 32 shown in FIG.

  The client device 32 implements the processing functions of the second embodiment by executing a program recorded on a computer-readable recording medium, for example. A program describing the processing contents to be executed by the client device 32 can be recorded on various recording media. For example, a program to be executed by the client device 32 can be stored in the HDD 63. The processor 61 loads at least a part of the program in the HDD 63 into the RAM 62 and executes the program. The program to be executed by the client device 32 can also be recorded on a portable recording medium such as the optical disc 74, the memory device 75, and the memory card 77. The program stored in the portable recording medium becomes executable after being installed in the HDD 63 under the control of the processor 61, for example. The processor 61 can also read and execute the program directly from the portable recording medium.

Next, the correction information table will be described. FIG. 5 is a diagram illustrating an example of a correction information table in the second embodiment.
The correction information table 100 is a table held by the correction information holding unit 48. The learning unit 46 updates the correction information table 100 when the command character string being input is corrected. The correction information table 100 is No. And a command before correction, a command after correction, and the number of corrections. The correction information is information in which items arranged in the horizontal direction are associated with each other.

  No. Is identification information that can uniquely identify the correction information. The command before modification is a command character string before modification. The corrected command is a corrected command character string. A regular command is set in the item of the command after correction.

  The number of revisions is the number of revisions from the command before revision to the command after revision. In other words, the correction information in which a large value is set for the number of corrections means that the correction has been performed many times in the past. Note that the number of corrections may be initialized every predetermined period or may be set for each user.

  For example, if there is the same pre-correction command, the client device 32 determines a correction candidate (post-correction command) to be notified to the user based on the number of corrections. Commands can be extracted as correction candidates. In other words, the client device 32 can perform input assistance that reflects an input mistake with a large number of appearances by using the number of corrections. In addition, the client device 32 can perform input assistance that reflects input errors that frequently occur by initializing the number of corrections every predetermined period. Further, the client device 32 can perform input assistance reflecting an input error for each user by setting the number of corrections for each user.

  The learning unit 46 updates the number of corrections when a correction that already exists in the correction information table 100 is executed. On the other hand, the learning unit 46 accumulates correction information when a correction that does not exist in the correction information table 100 is executed. For example, the learning unit 46 adds the correction information 101 to the correction information table 100 when a correction operation for correcting the command character string “ABFF” not in the correction information table 100 to the command character string “ABDFF” is executed.

  For example, the correction information table 100 is No. The information includes “1”, a pre-correction command “ABDF”, a post-correction command “ACEFE”, and a correction count “2”. This indicates that the correction operation for correcting the command character string “ABDF” to the command character string “ACEFE” has been performed “2” times in the past.

Next, the command information table will be described. FIG. 6 is a diagram illustrating an example of a command information table in the second embodiment.
The command information table 110 is a table held by the command information holding unit 47. The command information table 110 includes items of commands, processing contents, and usage conditions (relation information). The command information is information in which the items arranged in the horizontal direction are associated with each other.

  A regular command is set in the command item. The processing content is the content of processing executed by the server device 31 that has received the command character string. The use condition is a condition that must be satisfied when a regular command set in the command item is used. The use condition is information regarding the relationship with other regular commands. The usage conditions include a prerequisite command and a command that cannot be used together. A precondition command is a regular command that must be entered first. In the precondition command, for example, when “reservation from vacant seat inquiry” is performed, “vacant seat inquiry” is set as a precondition because it is necessary to confirm the vacancy status first. A regular command that is a prerequisite is set.

  The command that cannot be used together is a regular command that cannot be used at the same time. A regular command that cannot be used together is set in the item of the command that cannot be used together. For example, “Reservation information copy” and “Reservation information copy” are not expected to be performed in the same series of processes. "EC" is set. For the regular command set in the command item, the regular command set in the prerequisite command is included in the command history, and the regular command set in the command that cannot be used together is not included in the command history. If the conditions are met.

  For example, the command information table 110 includes information on the command “ADCF”, the processing content “reservation from empty seat inquiry”, the preconditions “ABDF” and “ACDF”, and the combined use impossible “DBF”. This is because the processing content of the command “ADCF” is “reservation from vacant seat inquiry”, and it is necessary that the regular commands “ABDF” and “ACDF” have been input first (required to be included in the command history). ). Further, the command “ADCF” indicates that it cannot be used when the regular command “DBF” has been input (included in the command history).

Next, a series of command character string input processing will be described. FIG. 7 is a flowchart of input processing in the second embodiment.
The input process is a process performed by the control unit 40. The control unit 40 accepts continuous command character string input in the input process.

  [Step S1] The control unit 40 performs a command character string input process. In the command character string input process, the control unit 40 receives an input of a regular command from the user, and transmits the received regular command to the server device 31. The command character string input process will be described later in detail with reference to FIG.

  [Step S2] The control unit 40 updates the command history. The control unit 40 adds the regular command transmitted to the server device 31 in the command character string input process to the command history. Thus, whenever the control unit 40 transmits a regular command, the transmitted regular command is added to the command history. Therefore, the control unit 40 can identify the regular command that has been input (input) first in the process of inputting the continuous command character string by using the command history.

  [Step S3] The control unit 40 determines whether or not the input of the command character string has been completed. For example, the control unit 40 determines that all the input of the continuous command character string has been completed when the receiving unit 41 has not received an input operation for a certain period of time. In addition, when the receiving unit 41 receives an intention to end the input of the command character string from the user, the control unit 40 determines that all the input of the continuous command character string has been completed.

  When it is determined that the input of the command character string has been completed, the control unit 40 proceeds to step S4, and when it is determined that the input of the command character string has not been completed, the control unit 40 proceeds to step S1.

  [Step S4] The control unit 40 initializes the command history accumulated in the process of inputting the continuous command character string. When the control unit 40 initializes the command history, the input process ends.

Next, command character string input processing will be described with reference to FIG. FIG. 8 is a flowchart of command character string input processing in the second embodiment.
The command character string input process is a process executed in step S1 of the input process. The command character string input process is a process executed by the control unit 40.

[Step S11] The control unit 40 receives an input operation from the user via the reception unit 41.
[Step S12] The control unit 40 updates the input history based on the input operation received by the receiving unit 41.

  [Step S <b> 13] The control unit 40 performs correction determination processing via the correction determination unit 44. When the input operation accepted by the receiving unit 41 is a correction operation, the correction determination unit 44 determines that there is an input error in the command character string being input, and determines that it is time to present correction candidates. The correction determination unit 44 determines that there is an input error in the command character string being input and presents correction candidates when there is no regular command that partially includes the command character string being input. Is determined. In addition, the correction determination unit 44 determines that there is an input error in the command character string being input when all of the regular commands including part of the command character string being input cannot be used in relation to the command history, It is determined that it is time to present a correction candidate.

  [Step S14] As a result of the correction determination process, the control unit 40 proceeds to step S15 when it is determined that it is time to present a correction candidate for the command character string that is being input, and the correction candidate for the command character string that is being input. If it is determined that it is not time to present, the process proceeds to step S17.

  [Step S15] The control unit 40 performs correction candidate extraction processing via the correction candidate extraction unit 45. Based on the command character string being input and the correction information table 100, the correction candidate extraction unit 45 determines a regular command that is a correction candidate for the command character string being input.

  [Step S16] The control unit 40 notifies the user of the regular command extracted as a correction candidate via the notification unit 42. For example, the notification unit 42 notifies the user of correction candidates through the monitor 71.

  [Step S17] The control unit 40 determines whether or not the input of the command character string is completed. For example, the control unit 40 determines that the input of the command character string is completed when the receiving unit 41 receives an input operation of the transmission button. In addition, the control unit 40 determines that the input of the command character string is completed when the receiving unit 41 receives an intention to end the input of the command character string (for example, an input operation of the Enter key) from the user. Further, the control unit 40 determines that the input of the command character string has been completed when the input of the replacement operation for replacing the command character string being input by the receiving unit 41 with the correction candidate is received from the user.

  When it is determined that the input of the command character string has been completed, the control unit 40 proceeds to step S18, and when it is determined that the input of the command character string has not been completed, the control unit 40 proceeds to step S11.

[Step S <b> 18] The control unit 40 transmits a command character string to the server device 31 via the communication unit 49.
[Step S19] The control unit 40 receives the response result of the command character string transmitted via the communication unit 49.

  [Step S20] The control unit 40 determines whether the response result received by the communication unit 49 is an error. When it is determined that the response result received by the communication unit 49 is an error, the control unit 40 proceeds to step S15, and when it is determined that the response result received by the communication unit 49 is not an error, the control unit 40 proceeds to step S21.

  [Step S <b> 21] The control unit 40 performs a learning process via the learning unit 46. The learning unit 46 generates a command before correction from the input history, and stores it in the correction information table 100 in association with the transmitted command character string (command after correction). As described above, the client device 32 can reflect an input error or the like having a large number of appearances when extracting a correction candidate by accumulating a history of corrections performed during the command character string input process. Further, the client device 32 learns after receiving the response result from the server device 31 in this way, and thus does not accumulate a history of correction to the command character string that accepts an error notification from the server device 31. .

  [Step S22] The control unit 40 initializes the input history. The control unit 40 initializes the input history, assuming that one command character string has been input. When the control unit 40 initializes the input history, the command character string input process ends.

  The command character string input process has been described above. According to the command character string input process, the client device 32 determines whether it is time to present a correction candidate for the command character string being input. If the client device 32 determines that it is time to present a correction candidate, the client device 32 extracts and notifies the correction candidate. Further, when the correction is performed while the command character string is being input, the client device 32 learns the correction (accumulation history is stored).

Next, the correction determination process will be described with reference to FIG. FIG. 9 is a flowchart of the correction determination process in the second embodiment.
The correction determination process is a process performed in step S13 of the command character string input process. The correction determination process is a process executed by the correction determination unit 44.

  [Step S31] The correction determination unit 44 determines whether or not the input operation received by the reception unit 41 is a correction operation based on the input history. The correction determination unit 44 proceeds to step S37 when determining that the input operation received by the reception unit 41 is a correction operation, and proceeds to step S32 when determining that the input operation received by the reception unit 41 is not a correction operation. .

[Step S32] The correction determination unit 44 acquires the command character string being input. For example, the correction determination unit 44 acquires the command character string being input based on the input history.
[Step S33] The correction determination unit 44 searches the command information table 110 using the acquired command character string being input.

  [Step S34] As a result of the search, the correction determination unit 44 determines whether or not there is a regular command that partially includes the command character string being input. If the correction determination unit 44 determines that there is a regular command that partially includes the command character string being input, the correction determination unit 44 proceeds to step S35, and determines that there is no regular command that partially includes the command character string that is being input. If so, the process proceeds to step S37.

  [Step S35] Based on the command history and the command information, the correction determination unit 44 sets the use condition in relation to the normal command previously input among the normal commands including part of the command character string being input. It is determined whether there is a regular command that satisfies the condition. If the correction determination unit 44 determines that there is a normal command satisfying the usage condition in relation to the normal command previously input among the normal commands partially including the command character string being input, the process proceeds to step S36. Proceed. In addition, when the correction determination unit 44 determines that there is no regular command that satisfies the usage condition in relation to the regular command previously input among the regular commands including part of the command character string being input. Proceed to step S37.

[Step S36] The correction determination unit 44 determines that it is not time to present correction candidates. When the correction determination unit 44 finishes the determination, the correction determination process ends.
[Step S37] The correction determination unit 44 determines that it is time to present correction candidates. When the correction determination unit 44 finishes the determination, the correction determination process ends.

  The correction determination process has been described above. According to such correction determination processing, the correction determination unit 44 determines that it is time to present a correction candidate for the command character string being input when the reception unit 41 receives a correction operation. In addition, when there is no regular command that partially includes the command character string that is being input, the correction determination unit 44 determines that it is time to present a correction candidate for the command character string that is being input. In addition, the correction determination unit 44, even when there is a regular command that includes a part of the command being input, when the regular command does not satisfy the usage conditions in relation to the regular command that has been input first Is determined to be a timing for presenting correction candidates for the command character string being input.

  The input of the correction operation is a user's intention indication that there is an input error in the command character string being input. In addition, when there is no regular command that partially includes the command character string being input, the command character string being input does not become a regular command unless it is corrected. Therefore, it can be seen that there is an input error in the command character string being input. In addition, even if there is a regular command that includes part of the command string being entered, if the regular command does not satisfy the usage conditions in relation to the command history, the command string being entered is intended by the user. The command string is not considered. Therefore, it can be seen that there is an input error in the command character string being input.

  That is, the correction determination unit 44 determines an input error based on the input history, and determines that it is a timing for presenting a correction candidate for the command character string being input when it is determined that there is an input error.

Next, the correction candidate extraction process will be described with reference to FIG. FIG. 10 is a flowchart of the correction candidate extraction process in the second embodiment.
The correction candidate extraction process is a process performed in step S15 of the command character string input process. The correction candidate extraction process is a process executed by the correction candidate extraction unit 45.

  [Step S41] The correction candidate extraction unit 45 acquires the command character string being input. For example, the correction candidate extraction unit 45 acquires the command character string being input based on the input history.

[Step S42] The correction candidate extraction unit 45 searches the correction information table 100 using the command character string being input.
[Step S43] The correction candidate extraction unit 45 identifies correction information having a pre-correction command that matches the command character string being input from among a plurality of correction information.

[Step S44] The correction candidate extraction unit 45 acquires the command history from the input history holding unit 43.
[Step S45] The correction candidate extraction unit 45 determines, from the specified correction information, correction information having a corrected command (normal command) that satisfies the usage condition in relation to the normal command stored in the command history. Specifically, the correction information having the corrected command whose precondition is not satisfied by the normal command stored in the command history, and the corrected command in which the normal command stored in the command history is set to the combination prohibition condition Exclude correction information with. The correction candidate extraction unit 45 determines the correction information having the corrected command that satisfies the usage condition by excluding the correction information having the corrected command that does not satisfy the usage condition. By narrowing down the correction information that can be used in this way, the client device 32 can extract a corrected command that satisfies the usage conditions as a correction candidate.

  [Step S46] The correction candidate extraction unit 45 sorts the determined correction information in descending order of the number of corrections. In this way, by sorting the correction values in descending order, the correction candidate extraction unit 45 can rearrange the correction information in the order of the possibility that the correction is intended by the user.

  [Step S47] The correction candidate extraction unit 45 extracts a corrected command of correction information having the largest correction count value as a correction candidate for notifying the user. Note that the correction candidate extraction unit 45 may extract a corrected command of a plurality of correction information as a correction candidate.

  The correction candidate extraction process has been described above. According to such a correction candidate extraction process, the correction candidate extraction unit 45 specifies correction information having a command before correction that matches the command character string being input. The correction candidate extraction unit 45 determines correction information having a corrected command that satisfies the usage condition in relation to the command history from the specified correction information. The correction candidate extraction unit 45 sorts the determined correction information on the basis of the past number of corrections, and extracts a corrected command of correction information with a large number of corrections as a correction candidate. Thereby, the correction candidate extraction unit 45 can extract a regular command that has a high possibility of being intended by the user as a correction candidate.

Next, the learning process will be described with reference to FIG. FIG. 11 is a flowchart of the learning process in the second embodiment.
The learning process is a process performed in step S21 of the command character string input process. The learning process is a process executed by the learning unit 46.

[Step S51] The learning unit 46 identifies a regular command transmitted to the server device 31 during the command character string input process based on the input history.
[Step S52] Based on the input history, the learning unit 46 determines whether or not a replacement operation for replacing the command character string being input with a correction candidate has been performed during the command character string input process.

  If the learning unit 46 determines that a replacement operation for replacing the command being input with the command character string presented as a correction candidate has been performed during the command character string input process, the learning unit 46 proceeds to step S53. If the learning unit 46 determines that a command character string being input is not replaced with a command presented as a correction candidate during the command character string input process, the learning unit 46 proceeds to step S55.

[Step S53] The learning unit 46 identifies a command character string before being corrected to a regular command by replacement based on the input history.
[Step S54] The learning unit 46 identifies corresponding modification information based on the command character string before being modified into a regular command by the identified replacement and the identified regular command, and determines the number of modifications in the modification information table 100. Update.

  [Step S55] The learning unit 46 determines whether or not a correction operation has been input during the command character string input process based on the input history. The learning unit 46 proceeds to step S56 when it is determined that a correction operation has been input during the command character string input process, and the learning process when it is determined that no correction operation has been input during the command character string input process. Exit.

  [Step S56] The learning unit 46 executes a pre-correction command specifying process. In the pre-correction command specifying process, the learning unit 46 specifies a correction operation from the input history, and specifies a command character string immediately before the specified correction operation is performed as a pre-correction command.

[Step S57] The learning unit 46 updates the correction information table 100 with the pre-correction command specified by the pre-correction command specifying process and the regular command.
The above is the learning process. According to such learning processing, the client device 32 determines whether or not a replacement operation for replacing the command character string being input with the correction candidate is performed during the command character string input processing based on the input history. To do. When a replacement operation for replacing with a correction candidate is performed, the client device 32 identifies correction information corresponding to the performed replacement operation, and updates the correction information table 100. Further, the client device 32 determines whether or not a correction operation has been input during the command character string input process based on the input history. When the correction operation is input, the client device 32 identifies the command character string immediately before the correction operation is performed as the pre-correction command, and the correction information table based on the specified pre-correction command and the regular command. 100 is updated. That is, the client device 32 identifies the correction made during the command character string input process based on the input history, and accumulates (learns) the specified correction history.

Next, the pre-correction command specifying process will be described. FIG. 12 is a flowchart of the pre-correction command specifying process in the second embodiment.
The pre-correction command specifying process is a process performed in step S56 of the learning process. The pre-correction command specifying process is a process executed by the learning unit 46.

[Step S61] The learning unit 46 identifies a correction operation from the input history.
[Step S62] The learning unit 46 selects one correction operation from the specified correction operations.

[Step S63] The learning unit 46 specifies a command character string immediately before the selected correction operation is performed based on the input history.
[Step S64] The learning unit 46 specifies the specified command character string as a pre-correction command.

  [Step S65] The learning unit 46 determines whether or not all the specified correction operations have been selected. The learning unit 46 ends the pre-correction command specifying process when it is determined that all the specified correcting operations are selected, and proceeds to step S62 when it is determined that all the specified correcting operations are not selected.

Here, the pre-correction command specifying process will be described using a specific example. FIG. 13 is a diagram illustrating an example of a pre-correction command specifying process in the second embodiment.
There is an input history 200 “A, B, C, BS, BS, D, E, F, DEL, G”. The learning unit 46 specifies three correction operations (BS and DEL) of the input history 200. Then, the learning unit 46 specifies “ABC”, which is a command character string immediately before the first correction operation BS is input, as the pre-correction command 201. In addition, the learning unit 46 identifies “AD”, which is a command character string immediately before the second correction operation BS is input, as the pre-correction command 202. Finally, the learning unit 46 specifies “ADEF”, which is a command character string immediately before the third correction operation DEL is input, as the pre-correction command 203.

  The above is the command specifying process before correction. According to the pre-correction command specifying process, the learning unit 46 specifies the command character string immediately before the correction operation is performed as the pre-correction command based on the correction operation of the input history. When there are a plurality of correction operations in one input history, a plurality of pre-correction commands are specified from the one input history. By specifying a plurality of pre-correction commands in this way, a plurality of correction information can be derived from one input history, and correction history can be accumulated efficiently.

  The above is the client device 32 in the second embodiment. The client device 32 receives an input operation from the user and updates the input history based on the received input operation. The client device 32 determines (detects) an input error based on the input history, specifies correction information having a pre-correction command that matches the command character string being input, and sets a use condition from the specified correction information. Assume revision information with post-modification commands to satisfy. The client device 32 extracts a corrected command of correction information with a large number of corrections from the determined correction information as a correction candidate, and notifies the user. Further, the client device 32 identifies the correction made during the command character string input process based on the input history, and accumulates the specified correction history.

  In this way, when it is determined that there is an input error, the client device 32 can make the user recognize that the input error has occurred and prompt the correction by extracting the correction candidate and notifying it. Further, the client device 32 extracts correction candidates having a large number of corrections based on correction information in which past correction histories are accumulated, thereby reflecting an input error (such as a user's operation habit) having a large number of appearances. be able to. That is, the client device 32 can extract a regular command that is likely to be intended by the user as a correction candidate by extracting a correction candidate having a large number of corrections based on correction information in which past correction history is accumulated.

  In addition, the client device 32 determines correction information having a corrected command that satisfies the usage condition in relation to the command history. Therefore, the client device 32 can present a regular command that can be used in relation to the regular command (command history) input previously as a correction candidate. As a result, the client device 32 can improve the user's input operation.
