Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a conversion device and a conversion method for a character string to be input, and more particularly, for example, used in an information device having an e-mail function of transmitting and receiving a message, and using a Japanese " The present invention relates to a character string conversion device or a character string conversion method capable of efficiently performing “kana-kanji conversion”.
[0002]
[Prior art]
In recent years, “character code message type transmission / reception” represented by e-mail transmission / reception using a mobile phone has been widely spread as one of communication means.
With the expansion of the user group, the types of messages have also been spread to various usage forms such as personal use and business use.
Under these circumstances, various attempts to reduce the operation load of Japanese input have been put to practical use in order to more easily compose a message.
[0003]
For example, in Patent Document 1, in order to eliminate a complicated operation of reading and inputting by a kana, a specific operation is performed by inputting a leading character string of a reading character string already input (that is, a reading character string by a kana), A kana-kanji conversion method capable of inputting a notation character string converted to a corresponding kana-kanji character string is disclosed.
For example, after inputting reading information using a kana, `` there is a big problem in the Japanese language system, '' When there is confirmation, this is determined for each phrase "Japanese", "information", "processing", "system", "ni", "ok", "big", "task", "ni", Readings corresponding to “input”, “operation”, “no”, “efficiency”, “ga”, and “presence” are stored in a buffer (memory).
[0004]
Then, in the subsequent character input, for example, when reading and inputting "Ni" and pressing a key for abbreviated conversion, the first kana character of the reading input is "Ni", "Japanese", "Japanese""Information","Japanese information processing", "Japanese information processing system", and "input" are displayed as conversion candidates.
By selecting the desired conversion candidate, the operator can perform the kana-kanji conversion by simply inputting the first character of the kana, so in a scene where the same character string must be input everywhere. We can expect more efficient input.
[0005]
Further, in Patent Document 2, as the problem of Patent Document 1, as the number of input sentences increases, the first character of the reading input by the kana is stored as the same conversion candidate, so that the candidate desired by the operator is easily displayed as a candidate. Focusing on the inability to do so, a technique for simplifying the operation of narrowing down conversion candidates is described.
As rules for determining the extraction order, priority is given to rules such as "when the extracted text strings are consecutive, give priority to the preceding word" and "when the words of the extracted text strings are used alone". You can control not to display inferior characters as candidates,
A rule for combining and combining multiple character strings is provided, and a method of reducing selection operations by increasing the efficiency of character input and reducing the number of candidates is shown.
[0006]

[Problems to be solved by the invention]
On the other hand, in a messaging application represented by mail transmission and reception by a mobile phone as described above, there may be a case where the language is completely different depending on the communication partner.
For example, in a close relationship such as a family or a friend, it can be expected that emails are frequently exchanged in colloquial style.
In the case of messages to colleagues, it can be expected that abbreviations that can only be used within the company will frequently appear.
Furthermore, when sending e-mails to business partners, standard texts such as "I am always taking care of you" and "Thank you, thank you."
In the case of inputting text for messaging in the text input operation as described above, in many cases, the style and terms used in the message creation process are biased.
[0008]
However, when using the “Japanese input method that predicts characters that are likely to be used by the user from all past input character strings and uses it as an input candidate” as described above, the The already input character string information stored in the area is not always a valid character string in the next message creation. For this reason, there is a case where the effect cannot be obtained even if the learning content is reflected.
For example, to a friend, "I felt like I lost my car key at a drinking party in the meantime, but I don't recognize it." Immediately after creating a message in a style used only with close friends, If you try to compose a message to a business partner or a business partner, the character strings such as "During this time,""Drinkingparty,""Key,""I lost it," etc. Since there is no use value in creating messages to business partners and business partners, it is not possible to expect efficient character input.
In addition, a character string such as “drinking party” is determined and sent to the customer due to an operation error, which may cause a disadvantage to the user.
[0009]
Patent Document 2 also states that by recording already input character string information for each file to be edited, efficient conversion is possible when a desired changed character string differs depending on the file to be edited. Have been.
However, a message on a mobile phone is usually stored as one file, and a message on a mobile phone generally has a short total number of characters. With a learning string for each file, sufficient learning is performed until one message is completed. Therefore, there is a problem that the effect cannot be obtained.
[0010]
SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and when a message is created, an appropriate guess candidate character string corresponding to a message sending party is displayed, thereby reducing a user's character input load. Another object of the present invention is to provide a character string conversion device and a character string conversion method that can reduce disadvantages caused by erroneous character input due to an operation error.
In addition, by using such a character string conversion device, a highly convenient information terminal with an e-mail function can reduce the load of character input by a user and reduce disadvantages caused by erroneous character input due to an operation error. It is intended to provide a device (for example, a mobile phone device).
[0011]

In the present embodiment, as shown in FIG. 4, for example, four types of groups (group 1 to group 4) of friends, work, family, and business partners are assumed to be registered.
[0020]
Next, an operation of each functional module when a user (user) attempts to send a message to a specific address in the state of the database described above will be described.
1. Until the address group is identified.
FIG. 5 is a flowchart for explaining an operation performed when a user (user) selects a transmission destination of an e-mail in the address book until the group to which the address belongs is specified.
FIG. 6 is a diagram showing a transition example of the display screen of the display device 202 when the user determines the mail address.
First, an operation until an address group is specified will be described with reference to FIGS.
[0021]
(1) When the user (user) performs an operation for creating a new message on the e-mail client application 101 running on the mobile phone 201 (step S001), the e-mail client application 101 returns to the destination. A message editing screen having an address section, a subject section, and a body section is displayed (step S002).
An example of a message editing screen is shown at 601 in FIG.
As shown in FIG. 6, a message edit screen 601 includes a destination field for inputting a mail address of a destination, a destination group field for displaying a group name if the destination belongs to a specific group, and a subject of the message. And a text field for inputting the text of the message.
[0022]
(2) When the user specifies an address field and performs an operation for quoting an address book (step S003), the e-mail client application 101 issues a display request for an address list screen to the address book application 103. (Step S004).
(3) Upon receiving the address list screen display request, the address book application 103 displays the record information (record information) of the address record database 105 in a list format (step S005).
A display example 602 of FIG. 6 shows an address list screen (that is, a mail address selection screen).
The user can select one specific data record after checking the mail address and the name field of the record information of the address record database 105 on the address list screen 602.
[0023]
(4) It is assumed that the user has selected data "Hirohiko Tachibana" from the address list screen 602 (step S006).
Then, the address book application 103 selects an address data record corresponding to the data selected on the address list screen 602 from the address record database 105, and specifies ID = 4, which is the ID of the record (step S007).
(5) Further, in addition to the character string "tacbi@foo.co.jp" in the mail address field of the address data record, a group ID = 2 (group name: work) to which "Hirohiko Tachibana" belongs is specified (step S008). ).
[0024]
(6) The address book application 103 passes (returns) the character string “tacbi@foo.co.jp” in the mail address field and the information of the group ID = 2 to the e-mail client application 101 (returns), and displays the displayed address. The list screen 602 is deleted, and the series of processing ends (step S009).
(7) The e-mail client application 101 displays the mail address character string “tacbi@foo.co.jp” obtained from the address book application 103 and the group ID = 2 on the edit screen (that is, the message edit screen). The mail address and the group ID are reflected) and held (step S010).
Reference numeral 603 in FIG. 6 is an example of a message editing screen displaying the mail address character string “tacbi@foo.co.jp” and the group name “customer” quoted from the group ID.
[0025]
2. From opening the buffer to the end of editing according to the group.
FIG. 7 is a flowchart for explaining the operation from the opening of the learning buffer designated by the e-mail client application 101 to the end of editing from the start to the end of data editing using the user interface 107 for character editing. It is.
The opening of the learning buffer is to declare the start of reading and writing of the buffer (that is, the memory), and it means that the buffer is ready for reading and writing.
FIG. 8 is a diagram illustrating an example of a display screen when a user (user) performs character input.
First, an operation of selecting a learning buffer according to the specified ID will be described with reference to FIGS. 7 and 8.
[0026]
(1) When the user designates a text field (or a subject field) on the message editing screen 603 (see FIG. 6) whose address has been determined and performs an operation for starting to input a text (step S101), an e-mail is sent. Upon receiving the operation, the client application 101 issues a display request for a message editing screen to the character editing user interface 107 (step S102).
At this time, the e-mail client application 101 passes the information of the corresponding group number to the character editing user interface 107 as a start parameter.
[0027]
FIG. 8 is a screen example of the character editing user interface 107.
In the present embodiment, an editing area 801 for displaying a confirmed character string, an unconfirmed character area 802, and a comparison of an unconfirmed character string with a character string in an opened learning buffer result in learning data whose reading of the first character matches. Is displayed as a candidate character.
In the example of FIG. 8, the character string “Thank you very much. Candidates for "inner meeting" and "section manager Uchiyama" are displayed on the screen (step S103).
[0028]
(2) Next, the character editing user interface 107 specifies the learning buffer to be used to the learning buffer management unit 109 using the ID number corresponding to the partner group passed from the e-mail client application 101. (Step S104).
For example, if the ID number of the partner group passed from the e-mail client application 101 is “2”, the learning buffer 2 corresponding to the ID number is designated. (3) The learning buffer management unit 109 confirms that a learning buffer corresponding to the specified ID number exists (step S105), and if an existing buffer is specified, the buffer is used by the character editing user. Open the interface 107 (step S106).
[0029]
If the designated buffer does not exist, a new buffer area is newly created and open processing is performed (step S107).
By this open processing, the character editing user interface 107 performs the storage area of the result of the learning processing at the time of the subsequent character input and the target of the quoting processing of the past learning result to the specified buffer.
In the present embodiment, a learning buffer 2 (see FIG. 1), which is a learning buffer corresponding to group ID = 2, is opened.
That is, the buffer preparation is completed (S108).
[0030]
(4) Next, it is assumed that the user has started character input.
In the present embodiment, a message to “Hirohiko Tachibana” belonging to “work” with a group ID = 2 is created. Can you send it to the following? "
(5) When the user inputs the reading "always overwhelmed." (Step S109), it is confirmed whether or not the operation is an operation for finishing the editing (step S110), and the character is input. In the case of an input operation, the learning buffer management unit 109 and the character editing user interface 107 cooperate with each other to receive a guess candidate character display, a syntax analysis, a kana-kanji conversion, a candidate display to the user, and a correction operation from the user. Then, information processing for completing the input character as a kana-kanji mixed character is performed (step S111).
[0031]
(6) As a result of the information processing, when the user performs a determination operation for determining the kana-kanji mixed sentence (step S112), the character editing user interface 107 sets the learning buffer management as an event indicating that the determination operation has been performed. It is sent to the means 109 (step S113).
Upon receiving the event, the learning buffer management unit 109 learns the reading information and the determined character string information from the learning buffer that has been opened in step 106 or step S107 (S114), and determines the learning result. At the same time, the completion of the learning is notified to the character editing user interface 107, and the input of the next character is prompted (S115).
FIG. 9 shows an example of a learning result recorded in the learning buffer 2 which is a learning buffer corresponding to the group 2 (group name: work) in a table format.
In this learning operation, a character string that has been input and confirmed in the past may be simply divided into words and a word list may be created. Then, division may be performed.
[0032]
(7) Next, the character editing user interface 107 waits for a user input operation (that is, input processing) again.
When the user's input processing is performed (step S109), the user's operation is determined (step S110). A close request is issued (step S116).
Note that closing the buffer means declaring the end of reading / writing of the learning buffer.
[0033]
(8) Upon receiving the buffer close request, the learning buffer management unit 109 closes the learning buffer 2 (step S117), and issues a message to the effect to the character editing user interface 107 as an event to the effect (step S118).
Upon receiving the event issued by the learning buffer management unit 502 in step S118, the character editing user interface 107 saves information (edit data) edited by the user (step S119), and notifies the e-mail client application that the editing has been completed. A report is made (step S120).
[0034]
3. About the example where the buffer is referenced at the next use.
Next, a case where a user attempts to create a message to “Kaneko Katsura” belonging to group 2 from the address book application will be described with reference to FIGS.
(1) Until the user selects a target partner from the address book application (steps S001 to S011 in FIG. 5), the same processing as described above is performed, and the e-mail client 101 sets the address data record ID = 2 (Katsura Kaneko), and acquires group data record ID = 2 (work).
(2) Next, when the user starts editing, group ID = 2 is applied, and steps S001 to S008 (see FIG. 5) are the same as in the case of creating a message addressed to “Hirohiko Tachibana” described above. The process proceeds to.
However, the information shown in FIG. 9 is added to the learning buffer 2.
[0035]
Next, in the course of the user's correction operation in step S111 in FIG. 7, the learning buffer management unit 109 compares the contents of FIG. 9 with the user's input character (a pseudonym) in response to the user's character input operation. Those whose columns match are sequentially displayed in the guessed candidate display area 803 (see FIG. 8).
For example, if the user enters the sentence "I'm always indebted" and enters the first letter "i", the first letter is the same "I'm always indebted""Character string converted into kana-kanji and stored in learning buffer 2" is displayed in guessed candidate display area 803 as a candidate.
Therefore, the user can select and input the sentence "I'm always indebted" I wanted to input without performing a complicated conversion correction operation.
[0036]
4. About the example where the buffer is not referenced at the next use.
On the other hand, a case where the user attempts to create a message addressed to "Hiroo Aoi" belonging to group 1 from the address book application will be described with reference to FIGS.
(1) Until the user selects a target partner from the address book application 103 (from step S001 to step S011 in FIG. 5), the same processing as described above is performed, but as shown in FIG. The group to which "Hiro" belongs (group name: friend) has ID = 1.
Therefore, the e-mail client application 101 acquires the address data record ID = 1 (Hiroshi Aoi) and the group data record ID = 1 (friend).
[0037]
(2) Next, when the user starts editing, the group ID = 1 is applied, and the buffer for group 1 (group name: friend) is opened in the buffer open processing in steps S101 to S108 (see FIG. 7). You.
(3) Next, in the course of the user's correction operation in step S111, the learning buffer management unit 109 compares the contents of the buffer recorded as group 1 with the user's input characters in response to the user's character input operation. , The characters whose head character strings match are displayed in the guessed candidate display area 603 in order.
For example, it is assumed that a combination of a character string and a reading as shown in FIG. 10 is recorded as a buffer for groove 1 (that is, a learning buffer 1).
In this case, when the user enters "i", the character string "at home" appears, but a message to the other party belonging to the "friends" group, such as "I'm always indebted" or "I want to have" Since the display of characters that are not used is excluded from the options, it is possible to quickly select a target language.
[0038]
As described above, the character string conversion device according to the present embodiment includes a kana-kanji conversion means (a kana-kanji conversion engine 108) for converting an input kana character string into a kana-kanji notation character string, and an electronic message transmission partner. Are classified into a plurality of destination groups, and an address book data management means (address book application 103) for managing names and mail addresses of electronic message transmission destinations, and a plurality of destinations managed by the address book data management means. Each time an electronic message is created, a combination of an input kana character string and a notation character string obtained by converting the kana character string by the kana-kanji conversion means is stored as a learning result. A plurality of learning result storage means (learning buffer management means 109) for inputting a transmission destination name and creating an electronic message. Is started, the destination group to which the transmission destination belongs is specified, the learning result stored in the learning result storage means corresponding to the specified destination group is read, and the learning result is input using the read learning result. A character editing user interface means (character editing user interface 107) for displaying on the display unit a candidate for a notation character string that matches the leading character string of the kana character string, and a notation character string displayed by the character editing user interface means And selecting means for selecting one notation character string from the candidates.
[0039]
Therefore, when composing a message, it is possible to display an appropriate guess candidate character string according to the recipient of the message, thereby reducing the user's character input load and reducing the disadvantages caused by erroneous character input due to operation errors. Can be reduced.
[0040]
In addition, by using the character string conversion device according to the present embodiment with an information terminal device with an e-mail function (for example, the mobile phone device 201), the burden of character input by the user is reduced, and disadvantages due to erroneous character input due to an operation error are reduced. It is possible to provide an information terminal device with an e-mail function, which is excellent in convenience and can reduce the problem.
[0041]
