Description

  The present invention relates to an email creation word conversion device, an electronic device including the email creation word conversion device, an email creation word conversion method, and an email creation word conversion program.

When attempting to edit a mail message, the mail editor selects one word from a plurality of words that are candidates for conversion of the input kana characters and performs a conversion operation from the kana characters. For example, the cursor is moved using a button for moving the cursor position, and one word at the moved cursor position is selected. For example, when the kana character “no” is displayed as a conversion candidate “note”, “ride”, “extend”, “delivery”, “delivery date” in order, and the cursor is at the “note” position, “Delivery date” is selected by performing the button operation for moving the cursor to the adjacent word once 4 times, and the kana character “NO” is converted to “Delivery date”.
If the number of button operations is small, work efficiency in message editing will be improved. Therefore, for example, in Patent Document 1, mail transmission partners are classified into a plurality of transmission destination groups, and combinations of input characters and conversion candidates corresponding to the respective transmission destination groups are stored as learning results. A storage means has been proposed.

However, even if the email recipient belongs to the same recipient group, there are multiple conversion candidates when editing a message for one recipient and when editing a message for another recipient. One word selected from the words may be different. Therefore, the number of button operations when converting from a kana character to one word may be different. For example, in a workmate belonging to the same destination group, the word converted from the input kana character is different depending on whether the transmission partner is a boss, a colleague, a friend who likes the same hobby, etc. May be different. In such a case, depending on the transmission partner, the number of button operations for moving the cursor to the position of the word to be selected may increase.
As described above, in the mail message editing work, depending on the transmission partner, there is a problem that the work efficiency when selecting one word from a plurality of words that are candidates for conversion of the input kana characters is reduced. is there.

Hereinafter, specific embodiments will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a block diagram illustrating a configuration of a mail conversion word conversion device 1 according to the present embodiment. FIG. 2 is an external perspective view of the mobile phone 30 provided with the mail conversion word conversion device 1 of the present embodiment.

  The input unit 2 in FIG. 1 includes a plurality of input buttons 34 provided in the mobile phone 30 in FIG. An editor who edits a mail message in order to obtain a word to be used in an e-mail (hereinafter referred to as e-mail) to be created for one sender, presses the input button 34 to input a kana character. input. The input kana characters are stored as character information in the RAM 10 and sent to the control unit 5 that determines the order of output to the display unit 3.

  The non-volatile memory 7 includes, for example, an EEPROM (Electrically Erasable Programmable ROM), a flash memory, etc., and can store and erase stored contents, and retains memory even when power is not supplied.

  The nonvolatile memory 7 includes a storage unit 9 as a storage area. The storage unit 9 includes a table that stores the relationship between characters such as kana characters, a plurality of words, and the order in which the plurality of words are displayed on the display unit 3 for each of a plurality of transmission partners. Characters such as kana characters are characters to be input in order to obtain a plurality of words that may be used in an email. The rank is set according to the characteristics of each of a plurality of transmission partners. In an area other than the storage unit 9 in the nonvolatile memory 7, transmitted mail, received mail, and the like are stored.

  The display unit 3 is composed of a liquid crystal screen, for example. The display unit 3 displays a kana character input by the input button 34. Further, the display unit 3 displays a plurality of words that are candidates to be converted from kana characters.

  The operation unit 4 includes cursor buttons 32 and 33 provided on the mobile phone 30. By operating the cursor buttons 32 and 33 by the editor, one cursor moves within a range of display positions of a plurality of words that are candidates for conversion from kana characters.

  The selection unit 6 includes a selection button 31 provided on the mobile phone 30. By the operation of the selection button 31 by the editor, one word at a position where the cursor is stationary is selected from a plurality of words displayed on the display unit 3 that are candidates for conversion from the input kana characters. can do.

  The control unit 5 displays the characters input by the input unit 2 on the display unit 3. The control unit 5 refers to the storage unit 9 that stores the relationship between a plurality of words and ranks for one transmission partner corresponding to the input character, and thereby a plurality of words corresponding to the input character. Are displayed on the display unit 3 according to the order.

  The control unit 5 replaces the kana characters displayed on the display unit 3 with the words selected by the selection unit 6 and displays them. That is, the control unit 5 converts the kana character into a word selected by the selection unit 6 and displays it on the display unit 3.

  The control unit 5 is constituted by a CPU, and implements the functions of the input unit 2, the operation unit 4, the selection unit 6, and the display unit 3 by reading the program stored in the ROM 8 into the RAM 10 and executing it.

  Next, a plurality of tables for each transmission partner stored in the storage unit 9 will be described. FIG. 3A is a table showing the contents of the table of Mr. A as one transmission partner. In the present embodiment, an example in which “no” as a kana character is input by the input button 34 will be described.

  One record in the table of FIG. 3A includes items of kana characters, words, and ranks. The kana character column of the table stores the kana character "no" as a character to be input to obtain a plurality of words that may be used in the mail, and the word column has the kana character "no". Indicates multiple words that may be used in emails. That is, the plurality of words described in the word string are candidates to be converted from the kana character “NO”. The rank indicates the rank in which a plurality of words described in the word string are displayed on the display unit 3.

  FIG. 3B is a diagram illustrating a state in which a plurality of words described in the word column are displayed on the display unit 3 based on the table of Mr. A in FIG. The display unit 3 includes an editing area 35 for editing a mail message and a word display area 36 in which a plurality of words are displayed.

  The editing area 35 indicates that “NO” as a kana character input by the input button 34 is displayed. In the word display area 36, a plurality of words are arranged in order from the left side of the drawing to the right side and from the upper side of the drawing to the lower side according to the respective ranks. That is, words are displayed in the word display area 36 in the order of “delivery date 23, delivery 24, delivery 25, remaining 26, ride 27, drink 28”.

  The cursor 37 moves the positions of a plurality of words displayed in the word display area 36 by the cursor buttons 32 and 33. The cursor 37 in FIG. 3 (b) indicates that it is at the delivery date 23 position.

  In this embodiment, Mr. A is the supervisor of the editor at the workplace. The email messages that the editor has sent to Mr. A so far have many occurrences of words used in tasks such as “Delivery”, “Delivery”, “Delivery”, etc. The related word rank is higher. Also in the present embodiment, the editor selects “Delivery date 23” by using the selection button 31 among the plurality of words displayed in the word display area 36. When “delivery date 23” is selected by the selection button 31, the control unit 5 displays “delivery date” instead of “no” in the editing area 35.

  At this time, since the cursor 37 is already at the position of “delivery date 23”, the editor can select “delivery date 23” without operating the cursor buttons 32 and 33. That is, the number of operations by the cursor buttons 32 and 33 can be reduced. Therefore, the work efficiency in the editing work for converting the kana character “no” to “delivery date” is good.

  FIG. 4A is a table showing the contents of the table of Mr. B as one transmission partner. Mr. B's table is stored in the storage unit 9. FIG. 4B is a diagram illustrating a state in which a plurality of words described in the word column are displayed on the display unit 3 based on the table of Mr. B in FIG. As described with reference to FIGS. 3A and 3B, as an example, a case where the kana character “NO” is input by the input button 34 will be described.

  In the word display area 36 of FIG. 4B, “drink 28, ride 27, delivery 24, delivery 25, remaining 26, delivery date 23” based on the ranking of each word in the table of Mr. B in FIG. Display them in order.

  It is assumed that Mr. B in this embodiment is a colleague in the same workplace as the editor who edits the message of the mail, and has a lot of opportunities to participate in the drinking party. In the email messages that the editor has sent to Mr. B so far, a relatively large number of words used for purposes other than business such as “drink 28” and “ride 27” have appeared. Also in the present embodiment, the editor selects “drink 28” with the selection button 31 among a plurality of words displayed by the input character “NO”. When “drink 28” is selected by the selection button 31, the control unit 5 displays “drink” instead of “no” in the editing area 35.

  In such a case, since the cursor 37 is already at the position of “drink 28”, the editor can select “drink 28” without operating the cursor buttons 32 and 33. That is, the number of operations by the cursor buttons 32 and 33 can be reduced. Therefore, the efficiency of the message editing work is good.

  Thus, Mr. A and Mr. B are in the same workplace as the editor, and even if they are registered in the same group in the address book where the mail address is registered, one word corresponding to the kana character When trying to select from among a plurality of words displayed, the selected word may be different between Mr. A and Mr. B as the transmission partners. Therefore, a table composed of combinations of a plurality of words and ranks corresponding to the input characters is provided in the storage unit 9 separately for each of Mr. A and Mr. B. This improves the efficiency of editing mail messages.

  Next, a method for setting the rank in descending order of the number of appearances will be described. FIG. 5 is a table in which the number of appearances in the table of Mr. A stored in the storage unit 9 is described.

  The latest column in FIG. 5 indicates the number of words that appear in the message of the transmitted mail when the latest mail is transmitted to Mr. A. The previous column is the number of words that appear in the mail message one time before the latest mail. The column two times before is the number of words that appear in the message of the mail two times before the latest mail.

  In the present embodiment, the number of appearances in the message of the mail transmitted three times in the past, from the latest mail to the previous two mails, will be described. The number of appearances in the mail message three times before the latest mail is deleted.

  The column of the total number of appearances in FIG. 5 is a numerical value obtained by summing up the number of appearances in the most recent, previous one, and previous two columns. As shown in FIG. 5, the word rank is higher from the one with the highest total number of appearances. In this way, the order in which words that are likely to be selected are displayed is increased. Therefore, in the message editing operation, it is possible to improve the work efficiency of selecting one word from a plurality of words that are input kana character conversion candidates.

  Next, a processing method for displaying a plurality of words on the display unit 3 will be described. FIG. 6 is a flowchart of a program for displaying a plurality of words on the display unit 3. This program is executed when a message is being edited after a mail creation program is started and a mail transmission destination is set.

  In step S <b> 100, the control unit 5 in FIG. 1 reads a table corresponding to the mail transmission partner from the storage unit 9 into the RAM 10. In step S110, the control unit 5 displays the kana character input from the input button 34 of the input unit 2 in the editing area 35 of the display unit 3 (see FIGS. 3B and 4B).

  In step S <b> 120, the control unit 5 acquires a plurality of words corresponding to the input kana characters from the table in the order of the order of display on the display unit 3.

  In step S130, the control unit 5 displays the words in the word display area 36 of the display unit 3 according to the order in which a plurality of words are acquired (see FIGS. 3B and 4B).

  Next, a processing method for setting the order of displaying words on the display unit 3 will be described. FIG. 7 is a flowchart of a program for setting the order in which words are displayed on the display unit 3. In this embodiment, this program is executed when the mail transmission is successful. Hereinafter, the content of the process which the control part 5 performs is described. The flowchart of FIG. 7 shows processing for a plurality of words corresponding to one kana character which is “no”, for example.

  In step S200, the table is read from the storage unit 9 to the RAM 10. In step S210, the number of appearances two times before in the table of the RAM 10 is replaced with the number of appearances one time before and updated. In step S220, the previous appearance count of the table in the RAM 10 is replaced with the latest appearance count and updated. In step S230, the latest appearance count of the table in the RAM 10 is updated to zero.

  In step S240, the number of appearances of words in the transmitted mail is calculated. In step S250, it is determined whether or not the word in the message is a word stored in the table of the RAM 10. If it is a word stored in the table (Yes), the process proceeds to step S260, and if it is not a word stored in the table (No), the process proceeds to step S270.

  In step S260, the latest number of appearances of the same word in the table of RAM 10 is stored, and the process proceeds to step S280.

  In step S270, a record is added to the table of the RAM 10, and the word and the latest appearance count are stored. In step S280, the total number of appearances consisting of the latest number of occurrences of the word in the table of the RAM 10, the previous appearance, and the previous appearance is calculated.

  In step S290, the rank in the total number of appearances of words in the table of the RAM 10 is calculated and set. In step S300, a record that is 7th or lower in the table of RAM 10 is deleted. In step S300, if it is determined in step S250 that the word is the same as the word in the table of RAM 10, and no record is added in step S270, the record is not deleted. In step S <b> 310, the table in the storage unit 9 is deleted, and the table in the RAM 10 is stored in the storage unit 9.

  In this embodiment, a case where “no” is input as a kana character has been described, but another kana character may be used. In addition, the kana characters may be a plurality of kana characters such as “NO”.

  As described above, the e-mail creating word conversion device 1 according to the present embodiment includes the display unit 3 and kana characters as characters to be input in order to obtain a plurality of words that may be used in the e-mail. That stores the relationship between the plurality of words and the order in which the plurality of words are displayed on the display unit 3 in accordance with the characteristics of the transmission partner, Mr. A and Mr. B. Part 9, input part 2 for inputting characters to obtain a word to be used in an e-mail to be sent to one transmission partner, and for Mr. A and Mr. B corresponding to the inputted kana characters By referring to the relationship between the plurality of words and the rank, the control section 5 displays the plurality of words corresponding to the input kana characters on the display section 3 according to the rank, and the plurality of words displayed on the display section 3 Select words to use in emails Ku, includes an operation unit 4 for moving the cursor 37 for the selection, in order to transform the words to use the entered kana character, a selector 6 for selecting a word cursor 37 is moved, the.
