Abstract

PROBLEM TO BE SOLVED: To streamline a process of checking character strings entered in email.SOLUTION: A transmission operation detection unit 11 is configured to detect email transmission operations performed by a mailer that manages email. When the transmission operation detection unit 11 detects a transmission operation, a transmission interruption unit 12 interrupts transmission of the email by the mailer. Triggered by the detection by the transmission operation detection unit 11, a display control unit 50 displays on a display unit a list of character strings of a first type entered in predetermined items of the mailer in a selectable format. A conversion unit 31 converts the selected character strings of the first type into corresponding character strings of a second type. The display control unit 50 causes the character strings of the second type converted by the conversion unit 31 to be displayed near the respective character strings of the first type corresponding to the character strings of the second type on the display unit.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a mail confirmation device, a mail confirmation method, and a program, and more particularly, to a technique for confirming information input on an email creation screen before sending the email.

  In order to cope with the problem of input operation mistakes in data transmission such as when sending various information according to requests such as e-mail transmission or web application on a web browser, the transmission information requested for transmission is not transmitted immediately. A technique is known in which the information is temporarily suspended and then transmitted after the content confirmation by the sender is completed (see, for example, Patent Document 1).

Japanese Patent Laying-Open No. 2015-032047

  In the technique disclosed in the above document, when a transmission request is detected for transmission information such as an e-mail, confirmation information before transmission is generated by rewriting a part of the transmission information and presented to the sender. For this reason, the sender is forced to carefully confirm the pre-transmission confirmation information in order to find the rewritten error part, and thus it is possible to find an input error of the transmission information in the process.

  The above method is considered to be a very effective method from the viewpoint of finding input errors. On the other hand, since the sender is required to discover even information in which an error that does not originally exist is embedded, there is room for improvement from the viewpoint of speeding up the confirmation operation.

  The present invention has been made in view of these points, and an object of the present invention is to provide a technique for improving the efficiency of the confirmation process of a character string described in an e-mail.

  A first aspect of the present invention is a mail confirmation device. This apparatus interrupts transmission of an email by the mailer when a transmission operation detection unit that detects an email transmission operation performed by a mailer that manages email and the transmission operation detection unit detects a transmission operation. Triggered by detection by the transmission interruption unit and the transmission operation detection unit, a display control unit that displays a list of first type character strings input in predetermined items of the mailer on a display unit in a selectable manner is selected. And a conversion unit for converting into a second type character string corresponding to the first type character string. The display control unit arranges the second type character string converted by the conversion unit in the vicinity of the first type character string corresponding to the second type character string and causes the display unit to display the second type character string.

  It may further comprise a domain storage unit that stores in advance a second type character string of an organization corresponding to the domain of the mail address in association with the domain, and the conversion unit refers to the domain storage unit and refers to the mailer. Of the e-mail addresses input in, the domain name may be converted into the second type character string.

  A domain name acquisition unit that acquires a second-type character string of an organization corresponding to the domain of the email address via a network may be further provided, and the conversion unit may include a domain name among email addresses input to the mailer. May be converted into a second type character string.

  The display unit may further include a touch detection unit that detects a user's contact on the display unit, and the display control unit detects that the user has touched a character string displayed on the display unit by the touch detection unit. As a trigger, the second type character string converted by the conversion unit may be displayed on the display unit.

  When the conversion unit cannot convert the domain name of the mail address into the corresponding second type character string, the display control unit displays the first type character string corresponding to the domain name in a manner different from other character strings. May be displayed on the screen.

  The conversion unit uses, as the second type character string corresponding to the first type character string, the Japanese notation output by the character conversion software for Japanese provided in the mail confirmation device with the first type character string as an input. It may be output.

  The second aspect of the present invention is a mail confirmation method. The method includes a step of detecting an e-mail transmission operation performed in a mailer that manages e-mail, a step of interrupting transmission of an e-mail by the mailer when the transmission operation is detected, and a detection of the transmission operation. As a trigger, a step of displaying a list of first type character strings input to predetermined items of the mailer in a selectable manner on the display unit, and a second type character corresponding to the selected first type character string The processor executes a step of converting into a string and a step of arranging the converted second type character string in the vicinity of the first type character string corresponding to the second type character string and causing the display unit to display it. To do.

  The third aspect of the present invention is a program. The program includes a function of detecting an e-mail transmission operation performed by a mailer that manages e-mail in the computer, a function of interrupting e-mail transmission by the mailer when the transmission operation is detected, and the transmission. When the operation is detected, the first type character string input to the predetermined item of the mailer is displayed on the display unit in a selectable manner, and the first type character string corresponding to the selected first type character string is selected. A function of converting to a two-type character string; and a function of arranging the converted second-type character string in the vicinity of the first-type character string corresponding to the second-type character string and causing the display unit to display the second-type character string. make it happen.

  It should be noted that any combination of the above-described constituent elements and the expression of the present invention converted between a method, an apparatus, a system, a computer program, a data structure, a recording medium, etc. are also effective as an aspect of the present invention.

<Outline of the embodiment>
FIG. 1 is a diagram showing an external configuration of a mail confirmation system S according to the embodiment. Hereinafter, an outline of the mail confirmation system S according to the embodiment will be described with reference to FIG.
In general, on a mail creation screen of a mailer for transmitting an electronic mail, items to be input by the user such as a destination address, a mail subject, an attached file, and a body content are displayed in a variety of ways. The mail confirmation system S according to the embodiment provides the user with an opportunity to review the items that the user has entered in each item of the mailer prior to the user sending an email.

  The mail confirmation system S according to the embodiment includes a communication terminal 1, a network N, and a server 2. The network N is a communication network such as the Internet. The communication terminal 1 exchanges information with the mail confirmation system S via the network N. The server 2 is various servers existing on the communication network. More specifically, the server 2 is a mail server or a domain name search server.

The communication terminal 1 is a smartphone, a tablet PC (Personal Computer), a desktop PC, a notebook PC, or the like, and is a computer that includes calculation resources such as a CPU (Central Processing Unit) and a memory (not shown). The communication terminal 1 includes a mail confirmation unit 100, a display unit 200, and a mailer 300.
The display unit 200 is configured integrally with the communication terminal 1 when the communication terminal 1 is a smartphone, a tablet PC, a notebook PC, or the like. When the communication terminal 1 is a desktop PC, the display unit 200 can be a device independent of the communication terminal 1. FIG. 1 shows an example in which the display unit 200 is integrated with the communication terminal 1.

The mailer 300 is a general e-mail client, and is application software for sending and receiving e-mails and managing sent and received e-mails. When transmitting a mail, the user inputs a character string into a predetermined item displayed on the display unit 200 of the communication terminal 1 that executes the mailer 300.
The mail confirmation unit 100 monitors the mail transmission operation of the mailer 300 by the user. When the mail confirmation unit 100 detects a mail transmission operation of the mailer 300 by the user, the mail confirmation unit 100 provides the user with an opportunity to review whether or not each item is correctly input before the mailer 300 transmits the mail. The e-mail confirmation unit 100 is implemented as a plug-in of the mailer 300, for example.

The mail confirmation unit 100 provides an opportunity for the user to confirm whether various information input to each item on the mail creation screen provided by the mailer 300 is correct before sending the mail. Thereby, it can suppress that a user makes wrong transmission of a mail, a mistake of an attached file, etc. When the communication terminal 1 executes the mail check unit 100 together with the mailer 300, the communication terminal 1 functions as a mail check device that allows the user to check the description content input in each item on the mail creation screen.
Hereinafter, the mail confirmation unit 100 according to the embodiment will be described in more detail.

<Functional configuration and confirmation screen of email confirmation unit 100>
FIG. 2 is a diagram schematically illustrating a functional configuration of the mail confirmation unit 100 according to the embodiment. The mail confirmation unit 100 according to the embodiment includes a mailer control unit 10, an address management unit 20, a character string control unit 30, a confirmation operation management unit 40, and a display control unit 50.
The mailer control unit 10 controls mail transmission / reception in the mailer 300. Therefore, the mailer control unit 10 includes a transmission operation detection unit 11, a transmission interruption unit 12, and a transmission permission unit 13. The transmission operation detection unit 11 detects a mail transmission operation performed by the mailer 300 that manages electronic mail. The transmission interrupting unit 12 interrupts the mail transmission by the mailer 300 when the transmission operation detecting unit 11 detects the transmission operation. Once the transmission interruption unit 12 interrupts the mail transmission process by the mailer 300, the mailer 300 cannot transmit the mail until the user finishes confirming the description of the predetermined item. The transmission permission unit 13 permits the mailer 300 to transmit the mail whose transmission is interrupted by the transmission interruption unit 12 when the user finishes confirming the description of the predetermined item. Thereby, the user can obtain the opportunity to confirm the description entered in the mail creation screen of the mailer 300 before sending the mail.

  The display control unit 50 causes the display unit 200 to display a list of character strings input to predetermined items of the mailer 300 in a selectable manner triggered by detection by the transmission operation detection unit 11. Here, the “predetermined item” is a confirmation execution item extracted from the mail creation screen so that the mail confirmation unit 100 can confirm the user. It should be noted that which items the display control unit 50 extracts can be set by the user using an operation setting screen (not shown) of the mail confirmation unit 100.

FIG. 3 is a diagram illustrating an example of a confirmation screen displayed on the display unit 200 by the display control unit 50 according to the embodiment. The confirmation screen is a screen for displaying a list of character strings extracted from predetermined items on the mail creation screen. The display control unit 50 displays a confirmation screen in a window different from the window of the mailer 300 in the display unit 200.
In the example of the confirmation screen shown in FIG. 3, each item of the sender's mail address, a plurality of mail addresses as mail destinations, a mail subject, an attached file, and a body is extracted by the display control unit 50 and displayed in a list. . In the example shown in FIG. 3, icons for executing the “change setting”, “cancel”, “third party confirmation”, and “send” operations are also displayed in the confirmation screen.

  The “setting change” icon is an icon for causing the display unit 200 to display an operation setting screen for the user to set the operation of the mail confirmation unit 100. When the user selects setting change, the display control unit 50 displays the operation setting screen of the above-described mail confirmation unit 100 on the display unit 200. The “cancel” icon is an icon for the user to cancel the mail check operation. When the user selects cancel, the display control unit 50 erases the confirmation screen from the display unit 200.

  The “third party confirmation” icon is an icon for requesting confirmation from a third party different from the user after the user has confirmed all items. The “Third Party Confirmation” icon is used when, for example, a person who has the authority to confirm the email sent by the user in the organization to which the user belongs, such as the user's supervisor or the user's colleague as a third party, is registered on the operation setting screen. It becomes effective. The “send” icon is an icon for instructing the user to send mail to the mailer 300. The transmission permission unit 13 allows the mailer 300 to transmit the mail whose transmission is interrupted by the transmission interruption unit 12 when the user selects the “transmission” icon. For this reason, the “send” icon is effective when the user has confirmed all items listed on the confirmation screen.

  In this specification, the user “confirms” an item means that the display control unit 50 selects a character string corresponding to each item in the confirmation screen displayed on the display unit 200. For example, when the display unit 200 is a display screen that presents information to the user and a touch screen that also has a function of a touch panel that receives an operation from the user, the user can trace the character by tracing the character string displayed on the display unit 200. A column is selected and a confirmation operation is performed. When the display unit 200 is a monitor that does not have a touch panel function, a confirmation operation is performed by the user selecting a range of a character string with a cursor displayed on the display unit 200 using a pointing device such as a mouse.

  The confirmation screen shown in Fig. 3 shows that six email addresses with domains outside the organization to which the user belongs are displayed, and one of them, "cccc@ddd.com", has already been selected by the user. Is shown. As shown in FIG. 3, it is expressed that the mail address selected by the user is confirmed by the user because the background and the character color are reversed with respect to the mail address that is not so. In the example shown in FIG. 3, the background and the character color of the area selected by the user are inverted, but the method for indicating the selected area is not limited to this. In addition, for example, the selected character string may be underlined by a dotted line or a broken line, or the color of the character string may be simply changed. Although the details of the confirmation work will be described later, for the convenience of the following description, the act of the user selecting a character string for confirmation may be described as “tracing the character string”.

The address management unit 20 executes an operation related to a mail address in the mail creation screen. The address management unit 20 includes an address extraction unit 21, a classification unit 22, and an order change unit 23.
The address extraction unit 21 extracts the mail address input on the mail creation screen of the mailer 300. At this time, the address extraction unit 21 also extracts the type of item in which the extracted mail address is described. Here, the “type of item in which the e-mail address was described” is information indicating a destination (To), a carbon copy (Carbon copy; Cc), or a blind carbon copy (Bcc). The classification unit 22 classifies the email addresses extracted by the address extraction unit 21 into two or more address groups based on a predetermined domain classification standard. The display control unit 50 displays the mail address extracted by the address extraction unit 21 on the display unit 200 in a different manner for each address group.

  The confirmation screen shown in FIG. 3 shows an example in which the classification unit 22 classifies the email address extracted by the address extraction unit 21 into two address groups, that is, the domain of the sender's email address and the other domain. More specifically, in the confirmation screen shown in FIG. 3, an email address having the same domain as “abc.jp”, which is a domain of the organization to which the user of the email confirmation unit 100 belongs, and the user of the email confirmation unit 100 E-mail addresses having domains outside the organization different from the organization to which they belong are arranged at different positions.

  FIG. 4 is a diagram for explaining classification of address groups based on domains. In the example shown in FIG. 4, the classification unit 22 classifies the mail address for each domain when the mail addresses having domains outside the organization to which the user belongs are “domain1.com” and “domain2.com”. It shows a state. As shown in FIG. 4, the display control unit 50 displays mail addresses of different domains at different places in the display area of the display unit 200. Although not shown, the display control unit 50 may change the character color of the mail address or change the background color of the mail address for each domain.

The order changing unit 23 rearranges the order of the mail addresses displayed as a list on the display unit 200 according to whether or not the user has selected.
FIG. 5 is a diagram for explaining the rearrangement of mail addresses by the order changing unit 23 according to the embodiment. FIG. 5 shows a change in a part of the confirmation screen shown in FIG. 3 where a list of mail addresses having domains outside the organization to which the user of the mail confirmation unit 100 belongs is displayed. More specifically, when the user selects “cccc@ddd.com” which is one of the mail addresses in FIG. 5, the order changing unit 23 displays the selected mail address at the bottom of the other mail addresses. To do. Thereby, the user can finish the confirmation of the mail address by tracing the top of the list of mail addresses displayed in a list. This is particularly effective when the number of mail addresses extracted by the address extraction unit 21 is large. This is because it is possible to omit the user from scrolling the mail address list to confirm the mail address or moving the mouse cursor or the user's finger to the display position of the mail address for confirmation.

  The main purpose of the mail confirmation unit 100 is to suppress erroneous transmission of electronic mail. In particular, erroneous transmission of an email to a mail address having a domain outside the organization to which the user of the mail confirmation unit 100 belongs should be avoided than erroneous transmission to a mail address having a domain within the organization. it is conceivable that. In other words, it can be said that the time required for confirmation can be shortened by omitting or simplifying the confirmation work for the mail address having a domain outside the organization to which the user of the mail confirmation unit 100 belongs. Similarly, even if it is different from the organization to which the user of the email confirmation unit 100 belongs, if the email address of the organization closely related to the organization to which the user belongs, the confirmation work may be omitted. I can say that.

Therefore, the transmission permission unit 13 permits the mailer 300 to transmit mail even when a predetermined domain group is not selected from among the address groups. For example, in the example illustrated in FIG. 3, the transmission permission unit 13 displays the “transmission” icon for the “yyy@abc.jp”, which is an email address having the same domain as the sender's email address, even if the user does not perform confirmation. Activate. Thereby, it is possible to achieve a balance between suppression of erroneous mail transmission and reduction of the burden of confirmation work.
It should be noted that domains that can be omitted by the user can be set on the operation setting screen of the mail check unit 100.

A file attached to an e-mail is different from a character string such as an e-mail address or an e-mail subject. For this reason, it is difficult to confirm whether or not the contents are correct unless the user actually opens the file attached to the e-mail.
Therefore, when the file is attached to the e-mail, the transmission permission unit 13 selects all the character strings by the user and, in addition, the electronic file triggered by the user opening the attached file. Allow sending mail. Thereby, the mail confirmation part 100 can also suppress erroneous transmission of an attached file.

On the other hand, for example, when a password is attached to an attached file, the time required for the user to confirm the mail becomes longer. For this reason, in view of the cost-effectiveness of suppression of erroneous mail transmission and the time required for it, it is considered that there is a case where it is desired to omit confirmation of an attached file to which a password is attached.
Therefore, when a file is attached to the e-mail and the password is required to open the file, the transmission permission unit 13 sends the e-mail to the mailer 300 even if the attached file is unopened. May be permitted to be transmitted. The user can set whether or not the confirmation of the attached file can be omitted on the operation setting screen of the mail confirmation unit 100. Thereby, it is possible to balance the suppression of erroneous transmission of the attached file and the time required for the transmission.

Next, details of the confirmation work by the user will be described.
The confirmation operation management unit 40 manages confirmation work by the user. The confirmation operation management unit 40 includes a measurement unit 41, a determination unit 42, an item selection unit 43, and a touch detection unit 44.

  As described above, the e-mail confirmation unit 100 provides the user with a confirmation opportunity by tracing the character string such as the e-mail address displayed on the display unit 200. For this reason, for example, when the speed at which the user traces the character string is too high, there is a high probability that the user has not properly confirmed the address. In such a case, the confirmation work by the user is complicated, and even if time is required for the confirmation work, the effect of suppressing erroneous transmission may be reduced.

  Therefore, the measurement unit 41 measures the speed at which the user selects a character string. The determination unit 42 determines whether the selection of the character string by the user is valid or invalid based on the speed measured by the measurement unit 41. More specifically, when the speed measured by the measurement unit 41 is included in the reference speed range determined for determining the effectiveness of character string selection, the determination unit 42 selects the character string by the user. Judged to be valid. The user can set the reference speed range on the operation setting screen of the mail confirmation unit 100, but is stored as an initial value in a basic determination reference database described later.

  6A to 6C are diagrams for explaining the confirmation work. More specifically, FIG. 6A is a diagram showing a confirmation screen before the user starts confirmation work of “aaaa@bbb.com” which is an email address. FIG. 6B is a diagram illustrating a confirmation screen when the user selects a character string. FIG. 6C is a diagram showing a confirmation screen when the selection of the character string by the user is invalid, and a diagram showing a confirmation screen when the speed at which the user selects the character string exceeds the reference speed range. is there.

  As illustrated in FIGS. 6B to 6C, the display control unit 50 changes the display mode of the area selected by the user according to the selection speed and causes the display unit 200 to display the display mode. For example, in the example shown in FIG. 6C, the selection speed is within the reference speed range until the user selects the first character string “aa” of the mail address, and the background color of the selection area and the color of the character string are the same. Inverted. On the other hand, since the selection speed is high after the first character string “aa”, the color of the character string is not reversed and the background is vertical stripes.

  Thus, the determination part 42 can suppress the confirmation operation | work requested | required of a user becoming a body by determining the effectiveness of selection based on the speed of the character string selection by a user. In addition, the display control unit 50 changes the display mode of the area selected by the user according to the selection speed and causes the display unit 200 to display the display mode, so that the user looks at whether the character string selection is valid or invalid. I can grasp it.

  Note that the determination unit 42 may determine the validity of selection based on the character string selection time required from the start to the end of character selection, not the speed of character string selection. More specifically, if the character string selection time is shorter than a predetermined time, the determination unit 42 can invalidate the character string selection by the user. However, when the determination unit 42 determines the validity based on the character string selection time, the user quickly selects, for example, “aaaa @ bbb.” From “aaaa@bbb.com” and the last “com” Even if the portion “” is selected slowly, it is determined to be effective. Therefore, the determination unit 42 is more effective in determining effectiveness based on the selection speed rather than the character string selection time in that it can more effectively prevent the confirmation work required from the user from becoming a ghost.

  Further, as illustrated in FIGS. 6B to 6C, information indicating whether the selection of the character string is valid or invalid is displayed near the cursor used for the user to select the character string. More specifically, the display control unit 50 displays a humanoid icon displayed as if the cursor is in the vicinity of the cursor. The display control unit 50 indicates whether the selection of the character string by the user is valid or invalid by changing the shape of the humanoid icon. For example, as shown in FIG. 6B, when the character string selection is valid, a humanoid icon indicating that the user is walking with a smile is displayed. On the other hand, as shown in FIG. 6C, when the character string selection is invalid, a humanoid icon indicating that the user is running while sweating is displayed.

  As described above, when the determination by the determination unit 42 is valid, the display control unit 50 causes the display unit 200 to display information different from the invalid case, so that the user can select whether the character string selection is valid or invalid. You can see at a glance.

Next, a mail address character string conversion process performed by the character string control unit 30 that controls character string conversion in the mail confirmation unit 100 will be described.
The mail confirmation unit 100 according to the embodiment is mainly intended to suppress erroneous transmission of an electronic mail by a user. For this reason, the mail address is an important item among items to be confirmed by the user.

  The e-mail address is composed of a user name and a domain name with “@” in between. The e-mail address is usually a character string composed of a combination of 1-byte alphanumeric characters and symbols. For this reason, for example, double-byte characters such as kanji are not used in the mail address, but are substituted with Roman characters.

  The domain of the email address often corresponds to some organization such as a real company or public office. There may be various forms of the user name of the e-mail address. For example, if the user is Japanese nationality, it is considered that there are many cases where at least one of the last name and the first name is written in Roman letters. If the user name or domain name of a mail address consisting of a 1-byte character string can be converted into another type of character string such as Japanese, the efficiency of confirmation of the mail address by the user can be improved. It is considered possible.

  Therefore, the conversion unit 31 converts the first type character string selected by the user into a corresponding second type character string. In the example of the mail address, the first type character string is a 1-byte ASCII (American Standard Code for Information Interchange) character string, and the second type character string is, for example, a full-width Japanese character string. The display control unit 50 arranges the second type character string converted by the conversion unit 31 in the vicinity of the first type character string corresponding to the second type character string and causes the display unit 200 to display the second type character string. In the following description, it is assumed that the second type character string is a Japanese character string. However, the second type character string is not limited to a Japanese character string, and may be another two-byte character string.

  FIGS. 7A and 7B are diagrams illustrating examples of character string conversion by the conversion unit 31 according to the embodiment. More specifically, FIG. 7A shows the Japanese notation corresponding to the user name “ai” of the mail address “ai@ueoshoji.co.jp” and the domain name “ueoshoji.co.jp”. ”Is displayed in the vicinity of the user name and the domain name, respectively. FIG. 7B shows a Japanese notation corresponding to the user name “tom” of the email address “tom@ueoshoji.com” and a Japanese notation corresponding to the domain name “ueoshoji.com”. These show examples of displaying in the vicinity of the user name and the domain name, respectively.

  From the operation setting screen of the mail confirmation unit 100, the user can register the domain of the mail address and the Japanese notation corresponding to the communication terminal 1 in advance. More specifically, the domain name storage unit 32 stores the second type character string of the organization corresponding to the domain of the mail address in association with the domain. The conversion unit 31 refers to the domain name storage unit 32 and converts the domain name of the mail address input on the mail creation screen of the mailer 300 into a Japanese character string.

  The conversion unit 31 may acquire the Japanese character string of the organization corresponding to the domain of the mail address via the network N instead of or in addition to referring to the domain name storage unit 32. . More specifically, the domain name acquisition unit 33 first acquires the Japanese character string of the organization corresponding to the domain of the mail address via the domain name search server existing on the network N. Thereafter, the conversion unit 31 converts the domain name in the mail address input on the mail creation screen of the mailer 300 based on the Japanese character string acquired by the domain name acquisition unit 33. Thereby, even if the user does not register the Japanese notation corresponding to the domain in advance, the Japanese notation of the domain can be displayed at the time of confirmation work.

  For the user name of the mail address, the conversion unit 31 uses the ASCII character string as an input and the Japanese notation output by the character conversion software for Japanese provided in the communication terminal 1 as a Japanese character string corresponding to the ASCII character string. Output. Character conversion software is sometimes called IME (Input Method Editor). In the example shown in FIG. 7A, Japanese notation “ai” is displayed as an output of the IME that receives the user name “ai” as an input. In the example shown in FIG. 7B, a character string “to m” is displayed as an output of the IME that receives the user name “tom”. The character string “to m” is an example of a case where the character string is not appropriate as a Japanese character string, but it is still considered that it helps the user to confirm the mail address.

  In the example shown in FIG. 7A, a case where the Japanese character string corresponding to the domain name “ueoshoji.co.jp” is “Ageo Trading Co., Ltd.” is shown. This is at least one of whether the user has previously registered the Japanese name of the domain name in the communication terminal 1 or whether the Japanese character string corresponding to “ueoshoji.co.jp” has been registered in the domain name search server. This is one case. On the other hand, when the conversion unit 31 cannot convert the domain name of the mail address into the corresponding Japanese character string, the display control unit 50 displays the ASCII character string corresponding to the domain name in a manner different from other character strings. Displayed on the unit 200.

FIG. 7B shows an example in which the conversion unit 31 cannot acquire the Japanese notation corresponding to the domain name “ueoshoji.com”. As shown in FIG. 7B, in such a case, the display control unit 50 displays a message indicating that the domain name is unknown on the display unit 200 and changes the ASCII character string of the domain to bold italic. . Furthermore, the display control unit 50 also changes the background of the domain when the conversion unit 31 can acquire Japanese notation corresponding to the domain name.
In the example shown in FIGS. 6 and 7, the mail address “cccc@ddd.con” is also a typographical error although the top domain is originally “.com”, and the Japanese notation of the domain name is also unknown. Even if such a mail address is not being confirmed by the user, the display control unit 50 may display the mail address in a different manner so as to stand out from the other mail addresses. In the example shown in FIGS. 6 and 7, the mail address “cccc@ddd.con” has a larger font size than other mail addresses and is displayed as bold.

  If the conversion unit 31 cannot acquire the Japanese notation corresponding to the domain name, it is considered that the probability that the domain of the mail address is incorrect is higher than in the case where the conversion unit 31 does not. Therefore, when the conversion unit 31 cannot acquire the Japanese character string corresponding to the domain name, the display control unit 50 causes the display unit 200 to display the part in a manner different from the other, so that the user can select the domain name of the mail address. Can provide an opportunity to correct errors.

  Here, the display control unit 50 displays the Japanese character string acquired by the conversion unit 31 in the vicinity of the ASCII character string to be converted, when the cursor touches the character string to be checked. When the display unit 200 is a display device and is a touch screen having a touch panel, the touch detection unit 44 first detects a user's contact on the display unit 200. The display control unit 50 displays the Japanese character string converted by the conversion unit 31 when the touch detection unit 44 detects that the user has touched the ASCII character strings displayed as a list on the display unit 200. 200. When there is no user contact from the ASCII character string, the display control unit 50 deletes the Japanese character string. Thereby, since the Japanese character string is displayed on the display unit 200 only while the user is tracing the character string for confirmation, the display area of the display unit 200 can be prevented from becoming complicated. Further, since only the Japanese character string corresponding to the ASCII character string being checked by the user is displayed on the display unit 200, the check is easy.

  In the above, the character string conversion process at the time of confirmation of the mail address which is one of the confirmation items has been described. Items that the e-mail confirmation unit 100 causes the user to confirm are not limited to e-mail addresses, and there are various other items such as a subject, an attached file, and a text. From the viewpoint of suppressing erroneous transmission of electronic mails, it is preferable to make the user confirm all items for all electronic mails. However, for example, in the case of an e-mail addressed to the organization to which the user belongs, there may be a judgment that the user does not have to confirm all items in view of the cost effectiveness of the time required for the confirmation work.

Therefore, the item selection unit 43 selects, based on the domain of the email address, the type of item in which the character string to be displayed as a list on the display unit 200 is input on the email creation screen.
8A and 8B are diagrams schematically illustrating a data structure of a confirmation item database referred to by the item selection unit 43 according to the embodiment. The confirmation item database is composed of a basic determination reference database shown in FIG. 8A and a reference correction database shown in FIG.

  More specifically, FIG. 8A shows the data structure of a basic judgment criterion database that stores items that the mail confirmation unit 100 confirms with the user and the respective judgment criteria and initial values of the number of confirmation requests. Yes. FIG. 8B shows a data structure of a reference correction database that stores correction values of basic determination criteria for each domain. Each database shown in FIGS. 8A and 8B is stored in a storage unit (not shown) of the communication terminal 1.

  The item selection unit 43 refers to the reference correction database based on the domain name of the mail address input in “Destination” on the mail creation screen extracted by the address extraction unit 21. For example, when the domain name of the email address input in To includes only “xyz.uk”, the item selection unit 43 confirms two types of items, the destination input in To and the destination input in Cc. Select as target item. In this case, the user can send an e-mail without checking the subject and attached file. If the domain name of the email address input in “To” includes “klm.co.jp”, the item selection unit 43 selects all types of items stored in the basic criteria database as items to be checked. To do. In this case, the mailer 300 can transmit an e-mail only after the user has selected character strings corresponding to all items displayed on the display unit 200.

  In this way, the item selection unit 43 selects the type of item in which the character string to be confirmed by the user is input based on the domain of the mail address, thereby suppressing the confirmation work before sending the email and the erroneous transmission suppression. Can balance.

  Note that, as shown in the basic determination criterion database of FIG. 8A, the determination criterion varies depending on the type of item. Therefore, the determination unit 42 refers to the basic determination criterion database, reads the determination criterion for each item, changes the reference speed range according to the item type, and determines the effectiveness of the selection operation by the user. For example, the determination unit 42 first acquires Q1 (character / second) from P1 (character / second) as an initial value of the reference speed range of the mail address input in To. The domain name storage unit 32 further determines the effectiveness of the selection operation by the user within a reference speed range determined for each domain of the mail address. For example, when the domain name of the mail address input in To is “hij.net”, the item selection unit 43 acquires a value of 0.9 times as the speed correction value. Therefore, the determination unit 42 adopts P1 × 0.9 (character / second) to Q1 × 0.9 (character / second) as the reference speed range, and determines the effectiveness of the selection by the user.

  Here, when requesting more careful confirmation from the user, the determination unit 42 may cause the character string to be confirmed a plurality of times. More specifically, the determination unit 42 counts the number of times that the user's character string selection operation is determined to be valid for each item, and the number exceeds the number of confirmation requests determined for each item. Confirm that the selection by the user is valid. As shown in FIG. 8A, the initial value of the number of confirmation requests is stored in the confirmation item database in association with each item. Further, as shown in FIG. 8B, the correction value of the number of confirmation requests is stored in the reference correction database in association with each domain.

  As described above, the determination unit 42 employs the number of confirmation requests set for each item, so that the time spent by the user for the confirmation work can be changed according to the importance of the item. Further, by correcting the number of confirmation requests according to the domain of the mail address, it is possible to adjust the time that the user spends for the confirmation work according to the destination.

<Processing flow>
FIG. 9 is a flowchart for explaining the flow of the mail confirmation process executed by the mail confirmation unit 100 according to the embodiment. The process in this flowchart starts when the mailer 300 is activated in the communication terminal 1, for example.

  The transmission interrupting unit 12 waits for the user to perform an email transmission operation in the mailer 300 (S2). While the transmission operation by the user is not detected (No in S4), the process returns to step S2 and the transmission interruption unit 12 continues to wait for the e-mail transmission operation. When the transmission interruption unit 12 detects a transmission operation (Yes in S4), the address extraction unit 21 extracts an email address described on the email creation screen of the mailer 300 (S6). The domain name acquisition unit 33 acquires the domain of the email address extracted by the address extraction unit 21 (S8).

  The item selection unit 43 selects a confirmation item to be confirmed by the user based on the domain acquired by the domain name acquisition unit 33 (S10). The display control unit 50 causes the display unit 200 to display a list of character strings input to the confirmation items acquired by the item selection unit 43 (S12). The determination unit 42 waits for a user's confirmation operation for each item displayed in a list on the display unit 200 (S14). While there is no confirmation operation by the user (No in S16), the process returns to step S14, and the determination unit 42 continues to wait for the confirmation operation by the user.

When the confirmation operation by the user is detected (Yes in S16), the determination unit 42 determines the validity of the confirmation operation (S18). If the confirmation operation is not valid (No in S20), the process returns to step S14 and the determination unit 42 continues to wait for the confirmation operation by the user. Even when the confirmation operation is valid (Yes in S20) and the user has not confirmed all items (No in S22), the determination unit 42 returns to step S14 and continues to wait for the confirmation operation by the user. .
If the confirmation operation is valid (Yes in S20) and the user confirms all items (Yes in S22), the processing in this flowchart ends.

FIG. 10 is a flowchart for explaining the flow of the verification operation validity determination process executed by the determination unit 42 according to the embodiment, and is a diagram showing step S18 in FIG. 9 in more detail.
The determination unit 42 refers to the basic determination criterion database and the criterion correction database, and acquires a determination criterion for determining the effectiveness of the confirmation operation (S1802). The measurement unit 41 detects the speed of the touch operation by the user (S1804). When the speed detected by the measurement unit 41 is within the reference speed range (Yes in S1806), the determination unit 42 determines that the confirmation operation by the user is valid (S1808). When the speed detected by the measurement unit 41 is out of the reference speed range (No in S1806), the determination unit 42 determines that the confirmation operation by the user is invalid (S1810).

As described above, according to the mail confirmation system S according to the embodiment, it is possible to provide a technique for improving the efficiency of the confirmation process of the character string described in the electronic mail. In particular, since the Japanese character string corresponding to the ASCII character string is displayed during the confirmation work, the efficiency of the user's confirmation work can be improved.
In addition, since the domain name of the mail address is acquired from the domain name search server on the network N, the Japanese name of the domain name can be displayed even if the user has not previously registered the Japanese name corresponding to the domain. it can. Furthermore, when the Japanese representation of the domain name cannot be acquired, the domain name is displayed in a different manner from the case where it can be acquired. If the domain name cannot be acquired, it is highly probable that the domain name is incorrect, so the user can focus on checking such an e-mail address.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. In particular, the specific embodiments of the distribution / integration of the devices are not limited to those illustrated above, and all or a part thereof may be added in arbitrary units according to various additions or according to functional loads.
