Description

  The present invention sets a character input operation in a program for giving a function for inputting characters to an active application in an information processing apparatus, an information processing apparatus having the function, and an information processing apparatus having a character input function On how to do.

  In many of the operation units of portable information processing apparatuses typified by cellular phones, a plurality of kana characters and alphabetic characters are assigned to the numeric keys “0” to “9”. When entering a mode for entering characters into the running application, these numeric keys function as character keys for hiragana input, and the user continues to press the same character key until the desired kana character is called. Enter the reading string. In addition, each character key can be switched to a numeric input key or an alphabetic input key by an operation of switching the input mode.

  In a conventional portable information processing apparatus, in order to eliminate the poor operability of character input, every time a reading character string changes, a predictive conversion process is performed to extract a converted character string that matches the character string in the forward direction. A list of extracted candidates is displayed (see Patent Document 1). In addition, according to post-conversion operation after assembling the reading character string, a function for converting numbers and alphabetic character strings corresponding to the previous key operations is also set (see Patent Document 2).

  Furthermore, in an information processing apparatus that launches a software keyboard on a touch panel such as a smartphone and accepts an operation for character input, the keyboard display is changed according to an operation for switching the character type to be input (Patent Document 3). See).

FIG. 14 shows an example of a software keyboard similar to that disclosed in Patent Document 3.
Specifically, the software keyboard of FIG. 14 is launched together with the e-mail creation screen, and four function keys are arranged on the left and right sides with the character keys 30 arranged in 4 rows × 3 columns. ing.

  Immediately after startup, a keyboard for hiragana input is displayed as shown in FIG. Among the function keys, the function key 31 arranged at the lower left corner is set with an input mode switching function (hereinafter, the key 31 is referred to as a “switching key 31”). When the switching key 31 is operated, the display is switched to an alphabetic input keyboard as shown in FIG. 14 (2) or a numeric input keyboard as shown in FIG. 14 (3). In these keyboards, input is generally performed using single-byte characters.

A function key 32 above the switching key 31 is set with a function for calling a palette display of special characters such as pictograms, emoticons, symbols, and the like (hereinafter, this key 32 is referred to as a “pallet call key 32”). .
In the hiragana input mode, when a reading character string is assembled by operating the character key 30, a predictive conversion process is performed to extract candidates having readings that coincide with the reading character string, and for input of the reading character string. Based on the type of the operated character key and the operation order, conversion candidates are created for each character type of alphabet, number, and katakana. Hereinafter, this process is referred to as “alphanumeric / kana conversion”, and the created conversion candidate is referred to as “alphanumeric / kana conversion candidate”. Alphanumeric / kana conversion candidates are arranged according to a predetermined order at the tail of the list of candidates extracted by the predictive conversion process.

  FIG. 15 shows a display example of candidates when the character string “Kasana” is assembled with the hiragana input keyboard shown in FIG. In this example, prediction conversion candidates are not extracted, and candidates based on alphanumeric kana conversion are displayed at the top. Further, in response to the assembly of the reading character string, the palette call key 32 is changed to a key 35 for designating narrowing down to only alphanumeric / kana conversion candidates. Hereinafter, this key 35 is referred to as “alphanumeric / kana conversion key 35”.

  In alphanumeric / kana conversion, for both katakana, alphabetic characters, and numbers, a character string that matches the key operation performed to assemble each reading character string is created using both full-width and half-width characters, and these are set as candidates. . For English letters, candidates are also created for each type of lowercase letters and uppercase letters, and candidates that start with an uppercase letter and have others as lowercase letters. As for numbers, candidates for numbers with commas and candidates converted to notations representing time and date are also created.

  While the operation of the character key 30 continues, as shown in the left hand of FIG. 15, a candidate display area 40 is set between the display area 41 on the application side and the display area 42 of the software keyboard. Is displayed. When the operation of the character key 30 is finished and the expansion button 43 in the area 40 is tapped, the candidate display area 40 is expanded as shown on the right side of the figure, and the lower candidates are also displayed. . The display of candidates when the alphanumeric / kana conversion key 35 is operated is performed in a generally similar manner. In addition, 43 'in a figure is a button for returning expansion | deployment display to the display of the original high-order candidate.

  Similarly, a portable information processing apparatus that does not use a touch panel also incorporates an input mode switching function and alphanumeric / kana conversion function.

  In the input of a character string represented by numbers, alphabets, and katakana, either half-width character input or full-width character input can be selected, but which one to select depends on the preference and necessity of the user. However, in conventional portable information processing devices, the input format switched by the switch key and the display order of alphanumeric / kana conversion candidates are fixed. Therefore, depending on the user, priority is given to input modes and candidates that do not match their preferences. There is a problem that it will be.

In addition, there are cases where the display reflecting the user's preference and habit cannot be realized even in the display of Kana-Kanji character string candidates.
For example, many users of younger generations replace the long sound symbol “-” with “to” (tilde), but as shown in FIG. 16, a character string including a long sound symbol is input as a reading character string. Then, only the candidate in which the long sound symbol is reflected is displayed. Therefore, in order to input a character string in which the long sound symbol is replaced with “to”, after confirming the character string closest to the target character string, delete the long sound symbol in the confirmed character string, It will be necessary to replace "~".

  In addition, there are users who have a habit of setting a punctuation mark at the end of a sentence in order to divide the sentence, while there are users who divide a sentence only by line breaks without setting a punctuation mark. In general, a punctuation mark is assigned to a character key 30a (see FIG. 14 and FIG. 15) located at the lower right corner together with a reading mark and other symbols (such as a crescent mark). Further, as shown in FIG. 17, the order of calling is fixed so that a reading point is called by the first operation of the character key 30a and a punctuation point is called by the second operation. Such a setting is convenient for a user who has a habit of setting a punctuation point, but it is more convenient for a user who does not have a habit of setting a punctuation point to give priority to other symbols.

  The present invention pays attention to the above-mentioned problems and makes it possible for any user to improve the convenience of character input by making it possible to easily input a character string that matches the preferences and habits of individual users. That is the issue.

  The program according to the present invention assembles and displays a pre-conversion character string, displays a conversion candidate character string, according to an operation by an operation unit including a plurality of character keys for kana character input that can be switched to input by other character types, A function as a character input unit for executing each process of determining a character string to be input to a running application is set in the computer.

In this character input unit, each of the character string groups determined within a predetermined period in the past is targeted for a plurality of types of determination formats each defined as representing the characteristics of the form adopted for the character string to be determined. Determine the appearance frequency of the fixed form, and based on these appearance frequencies, the analysis means that analyzes the superiority or inferiority of the appearance of the fixed character string between each fixed form, A setting for preferentially selecting a mode for inputting a character string in a form corresponding to a certain fixed form in the operation unit, or a character string in a form corresponding to a fixed form appearing predominantly Setting means for performing setting so that the candidate is preferentially displayed .

As a definite form that represents the characteristics of the form adopted for the definable character string, for example, a definite form is set for each character type of katakana, numbers, and alphabets as a character string having a structure unified by one character type. Can do. Furthermore, these character types can be divided into half-width characters and full-width characters, and a total of 6 types of determination formats can be set.
In addition, a confirmation format can be set for each of a case where a character string using a long sound symbol is confirmed and a case where a long sound symbol is replaced with “˜”. In addition, a confirmation format can be set for each of the case where a punctuation point is set at the end of a sentence and the case is confirmed, and the case where a line feed is performed without setting a punctuation point.

  According to the above analysis means and setting means, an environment in which it is easy to input a character string suitable for the user's preference and habit based on a fixed form that was frequently selected by the user in the character input work in the past predetermined period. Can be set. Therefore, any user can reduce the labor required for character input and improve convenience.

The analysis means of the character input processing unit sets a definite format for confirming a character string with a configuration unified with the character type for each of the plurality of character types, and discriminates the superiority or inferiority of the appearance frequency of the deterministic character string between these definite formats Can Further, the setting means determines that the analysis means has determined that the character string has appeared predominantly when displaying the candidate obtained by the process of converting the pre-conversion character string assembled by the operation of the character key into a character string of another character type. Can be set so that candidates by format are displayed at the top. In this way, when a conversion candidate based on a character string unified into one character type is displayed, it is possible to display a candidate in a definite format that is highly likely to be selected by the user at the top.

In the first embodiment of the character input processing unit, the analyzing means uses at least one character type of numbers, alphabetic characters, and katakana character types to determine a character string based on the character type using a single-byte character and the character type. Analyzes the superiority or inferiority of a fixed character string with a fixed form that determines a character string with double-byte characters. For the character types for which the above two finalized formats are set, the setting unit is dominant by the analysis unit among the input by half-width characters and the input by full-width characters when the character type to be input is switched according to the switching operation in the operation unit. It is set so that the input corresponding to the determined format determined to be is selected.

According to the above-described embodiment, when the user frequently performs input using double-byte characters, the mode of input using double-byte characters is set according to the operation of switching the character type to be input. On the other hand, when the user frequently performs input using single-byte characters, an input mode using single-byte characters is set according to an operation of switching the character type to be input.
.

In the second embodiment of the character input processing unit, the analyzing means determines whether the appearance frequency of the confirmed character string is superior or inferior in the confirmed format that uses the long sound symbol and the confirmed format that replaces the long sound symbol with “˜”. Is determined. The setting means operates the character input key when the analysis means determines that the appearance frequency of the definite form for confirming the character string in which the long clef symbol is replaced with "~" among the above two definite forms is dominant. Is set to display the candidates in the form after the replacement with "~" in the extracted candidate character string in response to the fact that the converted character string including the long sound symbol is assembled by To do.

  According to the above embodiment, for a user who often confirms by replacing the long clef symbol with “to”, according to the fact that the pre-conversion character string using the long clef symbol is assembled by operating the character input key Thus, it becomes possible to display conversion candidates based on the character string in which the long sound symbol is replaced with “˜”. This eliminates the need to change the long sound symbol to “to” and improves the operability.

In the third embodiment of the character input processing unit, the analysis unit determines the superiority or inferiority of the appearance frequency between a fixed form in which a punctuation point is set at the end of a sentence and a fixed form in which a line break is set without setting a punctuation point. The setting means, when the analysis means determines that the appearance frequency of the definite form in which line breaks are set without setting the punctuation is dominant among the two definite forms, according to the operation on the character key to which the punctuation is assigned Set to lower the order in which punctuation is called.

  According to the above embodiment, for users who have a habit of making a line break without setting a punctuation mark, it is possible to preferentially read symbols other than the punctuation mark even if the key to which the punctuation mark is assigned is operated. become.

The method according to the present invention includes an operation unit including a plurality of keys for inputting kana characters that can be switched to input by other character types, a display unit for displaying a screen of an active application, and a predetermined application is activated. Under the condition, the process of assembling the pre-conversion character string and displaying it on the display unit, displaying the conversion candidate character string on the display unit, and confirming the character string to be input to the application in accordance with the operation by the operation unit The operation of the character input processing unit is set for an information processing apparatus including a character input processing unit that executes the above. In this method, in the character string group determined within a predetermined period in the past by the information processing apparatus, targeting a plurality of types of determination formats respectively defined as representing the characteristics of the form adopted for the character string to be determined. Determine the appearance frequency of each confirmed format, analyze the superiority or inferiority of the appearance of the confirmed character string between each confirmed format based on these appearance frequencies, and confirm the dominant appearance based on the result of the analysis A mode for inputting a character string in a form corresponding to a format is preferentially selected in the operation unit, or a character string in a form corresponding to a confirmed form appearing predominantly is displayed in the conversion candidates. And a step of setting the operation of the character input processing unit so as to be displayed with priority .

  The above two steps correspond to the processing of the analysis unit and the setting unit described above, but these steps are not limited to those performed by the information processing apparatus. For example, in an external computer capable of communicating with the information processing device, the content determined from the information processing device receives the transmission of the history information of the character string determined in the past predetermined period, executes each step, and is determined as the setting content May be fed back to the information processing apparatus.

According to the present invention, based on the appearance frequency of each confirmed format in the character string group determined by the user's own operation, an environment is set in which it is easy to input a character string in a form that matches the user's preference and habit. Therefore, it is possible to reduce the labor of character input work for any user, and to provide a highly convenient information processing apparatus .

  Below, the example which applied this invention to the character input system (IME) integrated in the information processing apparatus (smartphone) of the form with which the display part and the operation part were integrated by the touch panel is demonstrated. Note that a similar character input system can be incorporated into a mobile phone other than a smartphone or an information processing apparatus without a communication function.

FIG. 1 is a functional block diagram of the character input system.
This character input system is software incorporated in a control unit (not shown) of the device in order to input characters to an application (mailer, notepad, etc.) running on the portable information processing device. The IME processing unit 1, the IME setting unit 2, the keyboard processing unit 3, the display unit 4, the basic dictionary 5, the learning dictionary 6, the analysis result storage unit 7, and the like. The mail storage unit 8 in FIG. 1 is a storage unit included in a mailer that is an application for character input, and is not included in the character input system. The mail storage unit 8 includes a transmission history storage unit 81 that stores a mail document transmitted to the outside, and a reception history storage unit 82 that stores a mail document received from the outside.

In the basic dictionary 5, dictionary data including the reading and notation (character string after conversion), part-of-speech information, priority, and the like are registered for each of a plurality of types of words. In addition, special forms of characters such as pictographs and emoticons are also registered in the basic dictionary 5.
In the learning dictionary 6, character strings determined according to user operations are accumulated retroactively to a certain number. The analysis result storage unit 7 stores a result of an analysis process executed by the preference analysis unit 18 described later.

  The keyboard processing unit 3 displays one of a plurality of types of keyboards 3A, 3B, 3C... With different input target character types on the touch panel, and accepts an operation. A mode (input mode) for inputting characters of the character type assigned to the keyboard is set by displaying the keyboard, so that there are as many input modes as there are keyboards. Normally, hiragana input using the hiragana keyboard 3A is selected, but the input mode can be switched according to the switching operation of the user. The input mode to be switched is selected by the input mode switching processing unit 11 in the IME processing unit 1.

The contents of the key operation accepted by the keyboard processing unit 3 are transferred to the IME processing unit 1, and the IME processing unit 1 executes processing according to the operation.
First, when a character key is operated, a reading character string (unconfirmed hiragana character string) is assembled by the reading character string assembling unit 12, and the conversion / prediction processing unit 14 forward-matches the reading character string from the basic dictionary 5. A word having a reading to be extracted is extracted. The extracted words are set as candidates that may be input (hereinafter referred to as “prediction candidates”), and are displayed as a list on the display unit 4 (display function of the touch panel) together with the reading character string.

The alphanumeric / kana conversion processing unit 13 also operates together with the conversion / prediction processing unit 14 to create an alphanumeric / kana conversion candidate corresponding to the assembled character string. Alphanumeric / kana conversion candidates are arranged after the list of prediction candidates, but may be displayed as higher candidates when there are few prediction candidates.
When the alphanumeric kana conversion key 35 (shown in FIG. 4) is operated in a state where the reading character string is assembled, the list display of conversion candidates is narrowed down to only alphanumeric kana conversion candidates.

  When the conversion key 33 (shown in FIG. 2) in the keyboard is operated in a state where a reading character string of a predetermined length is assembled, the conversion / prediction processing unit 14 causes the word whose reading matches the reading character string. Are extracted from the basic dictionary 5. A list of conversion candidates is created based on the extracted words and phrases and displayed on the display unit 4 instead of the list of prediction candidates.

  When an operation for confirming a candidate character string or reading character string in any of the above lists is performed, the confirmation processing unit 17 outputs the selected candidate or reading character string as a confirmed character string to a running application. Further, the determined character string is stored in the learning dictionary 6. Further, the connection candidate search unit 15 is activated in response to the output of the confirmed character string, performs a search on the learning dictionary 6, and extracts word candidates (connection candidates) that are input following the confirmed character string. A list of connection candidates is also displayed on the display unit 4, and when any candidate is selected, the character string of the candidate is output as a confirmed character string.

  When a palette call key 32 (to be described later) is operated, the keyboard processing unit 3 displays a palette such as pictograms instead of various software keyboards. In response to the display of this palette, the palette processing unit 16 is activated, and the selected character is confirmed in response to the selection of a predetermined character in the palette.

Further, the IME processing unit 1 includes an initial setting unit 19 and a preference analysis unit 18. The initial setting unit 19 is for setting the operation mode of the IME processing unit 1 to the state at the time of shipment.
The preference analysis unit 18 analyzes a mail document (a document created by the owner (user) of the information processing apparatus) stored in the transmission history storage unit 81 of the mail storage unit 8 and determines each predetermined fixed format. Determine the frequency of occurrence of the confirmed character string. This processing result is edited as an analysis result table ((c) in FIG. 5) to be described later for each mail document, and stored in the analysis result storage unit 7.

  Further, the preference analysis unit 18 analyzes the analysis result table accumulated in the analysis result storage unit 7 for each fixed period to determine a definite form having a high appearance frequency. Based on the determination result, the IME processing is performed. The process which selects the operation mode which the part 1 performs for character input is performed. Specifically, in this embodiment, the mode of operation of the input mode switching processing unit 11, the conversion / prediction processing unit 14, and the alphanumeric / kana conversion processing unit 13 is selected.

  The IME setting unit 2 is for performing settings related to various modes provided in the IME processing unit 1, and includes a mode initial setting unit 21, a user-specified mode setting unit 22, a preference mode setting unit 23, and the like. .

  The mode initial setting unit 21 is for setting the definition of the operation of the IME processing unit 1 at the time of shipment. The user designation mode setting unit 22 is for giving the highest priority to the designation when the definition to be set is designated by the user.

  The preference mode setting unit 23 is selected by the input mode switching processing unit 11, the alphanumeric / kana conversion processing unit 13, the conversion / prediction processing unit, and the palette processing unit 16 based on the results of the analysis and selection processing of the preference analysis unit 18. Set the action definition to operate in the specified mode. When the designation by the user is not valid, the setting by the preference mode setting unit 23 has priority over the initial setting. Hereinafter, specific examples of this setting are shown in FIGS.

  FIG. 2 shows three examples of the input mode setting in the above character input system in comparison. In either example, a basic hiragana keyboard is displayed, and eight function keys are arranged separately on the left and right with the character keys 30 arranged in four rows and three columns. The left-side function keys include a character type switching key 31 and a palette call key 32, and the right-side function keys include a conversion key 33 and a line feed key 34.

  The palette call key 32 is used to call a display screen for a palette of special characters such as pictograms, emoticons, and symbols. When a reading character string is inputted, an alphanumeric / kana conversion key 35 (shown in FIG. 4) appears instead of the palette call key 32.

  The hiragana keyboard of each case in FIG. 2 has the same key arrangement and the function assigned to each key, but the type of input mode that is switched by the lower left switching key 31 differs depending on the case. Accordingly, the display set in the switch key 31 is also different for each case.

  FIG. 2A shows a hiragana keyboard with initial settings, and a half-width alphabet input mode and a half-width number input mode are set as input modes that can be switched by operating the switching key 31. On the other hand, in the example of FIG. 2B, the object of switching is the full-width alphabet input mode and the full-width numeric input mode. In the example of FIG. 2C, in addition to the half-width alphabet input mode and the half-width numeric input mode, switching to the half-width katakana input mode is possible.

  For users who frequently determine numbers and alphabetic character strings using double-byte characters, input mode settings such as the example in FIG. 2B are presented instead of the initial settings in FIG. The In addition, an input mode setting as shown in the example of FIG. 2C is presented to a user who frequently determines a character string composed of katakana, alphabetic characters, and numbers using single-byte characters.

Similarly, regarding the display of candidates, a setting is selected so that candidates corresponding to a confirmation format that is frequently determined by the user are displayed at the top.
FIG. 3 shows three examples of the display of a prediction candidate list that is performed in conjunction with the input of a reading character string when a mail document is created. In either example, a reading character string “Kya” in a form in which a long symbol is placed at the end is assembled, and a prediction candidate list display area 40 is set between the display area 41 on the mailer side and the display area 42 on the keyboard. Has been. Note that an underline 45 indicating an unconfirmed state is applied to the reading character string in the mailer-side display area 41, and a cursor 44 is displayed on the right side. In the area 40, an expansion button 43 for enlarging the display of the prediction candidate list is provided.

  In any example, six prediction candidates are displayed in the area 40 in order from the top. In the example of FIG. 3A, the long sound symbol of the reading character string is maintained in all of these higher prediction candidates. On the other hand, in the example of FIG. 3B, a candidate long sound symbol having a long sound symbol arranged at the end is replaced with “˜”. In the example of FIG. 3C, the last long sound symbol and the middle long sound symbol are both replaced with “˜”.

  3B and 3C, the character string itself extracted from the basic dictionary 5 as a prediction candidate is the same as the candidate displayed in the example of FIG. As a result of replacing the long sound symbol of the extracted character string with “˜” in response to the setting of giving priority to “˜” as the representation of the long sound, as shown in FIGS. 3B and 3C. Display is realized. By such processing, variations of candidate display can be increased without increasing the dictionary data.

  A user as shown in FIG. 3A is presented to a user who frequently determines a character string including a long sound symbol. A display as shown in FIG. 3B is presented to a user who frequently determines a character string in which only the last long sound symbol is replaced with “˜”. A display as shown in FIG. 3 (C) is presented to a user who frequently determines a character string in which the long sound symbols at both the end and the middle position are replaced with “˜”.

  FIG. 4 shows three examples in comparison with respect to the display of a list of alphanumeric / kana conversion candidates. In either example, a detailed list is shown that is developed when the reading character string “Kasatakana” is assembled and only the alphanumeric and kana conversion candidates are displayed at the top.

The list in the example of FIG. 4A follows the default candidate order, and the candidates for each character type are displayed in the order of katakana, alphabetic characters, and numbers starting with the same hiragana character string candidate as the reading character string. Yes.
On the other hand, in the example of FIG. 4B, each candidate is arranged in the order of full-width katakana, full-width numeric, full-width English, half-width katakana, half-width numeric, half-width alphabet, and hiragana. In the example of FIG. 4C, each candidate is arranged in the order of half-width katakana, half-width alphabet, half-width numeric, full-width katakana, full-width alphabet, full-width numeric, and hiragana. Also, in any example, candidates for numbers include candidates for numbers with commas, candidates for time expressions, date expressions, etc., and candidates for alphabetic characters include candidates for uppercase letters, lowercase letters, only the top Candidates for capital letters are included.

  The display in FIG. 4B is often presented to a user who frequently determines a character string of each type of katakana, numbers, and alphabets in full-width, and inputs katakana more frequently than letters and numbers. The display shown in FIG. 4C is often provided for users who frequently determine katakana, alphabetic characters, and numeric character strings using half-width characters, and that input katakana more frequently than alphabetic and numeric characters.

  Furthermore, in this embodiment, it is also possible to change the calling order of input candidates for the operation of the lower left letter key 30a (see FIG. 2) to which symbols are assigned. Conventionally, as described with reference to FIG. 17, for the continuous operation of the character key 30 a, the order of calling is fixed so that calling is performed in the order of reading marks, punctuation marks, and other symbols. On the other hand, in this embodiment, when the fixed format for making a line break without inputting a punctuation mark is frequently selected, the calling order is changed so that other symbols are called with priority over the punctuation mark. The

  As shown in each of the above examples, in this embodiment, the user himself / herself inputs for document creation and is based on the character string that is determined and accompanied by the input mode to be switched, the display order of candidates, and the operation of character keys. The setting of the order of calling the punctuation is changed. Therefore, it is possible to easily input a character string that the user likes and uses or a character string in a favorite form.

  FIG. 5 shows a specific example of processing by the preference analysis unit 18 for one mail document, and FIG. 6 shows a procedure related to this processing. Hereinafter, description will be made along the flow shown in FIG. 6 with reference to FIG. 5 as appropriate.

  First, the preference analysis unit 18 reads an unprocessed mail document from the transmission history storage unit 81, and extracts text representing the substantial content (document created by the user that does not include the header portion) as an analysis target. (Step S1). FIG. 5A illustrates the analysis target text.

Next, the preference analysis unit 18 performs morphological analysis on the analysis target text (step S2). FIG. 5 (b) shows the result of morphological analysis for the text of FIG. 5 (a). The text is segmented in units of clauses, and the text in the clauses is divided into words by hyphens (-). Yes. Further, a symbol “\ n” is set at a line break, and this symbol is handled as one clause.
In addition, in the morphological analysis when “˜” is included in the text, “˜” is temporarily replaced with a long sound symbol, and word segmentation and part-of-speech discrimination are performed.

When the morpheme analysis is completed, the preference analysis unit 18 extracts characters that match the predetermined confirmation format for each of the twelve predetermined fixed formats, and counts the appearance frequency of the characters in each fixed format (step S3). . FIG.5 (c) shows the count result at the time of performing a count process based on the result of the morphological analysis of FIG.5 (b).
The palatability analysis unit 18 adds the date when the mail document, which is the original information, was created to a table indicating the counting result (hereinafter referred to as “analysis result table”), and saves it in the analysis result storage unit 7 ( Step S4).

  Among the fixed forms shown in Fig. 5 (c), "half-width numbers", "full-width numbers", "half-width English letters", "full-width English letters", "half-width katakana", and "full-width katakana" are all represented by the same character type. This is set to the character type of the confirmed character for the word that has been set. Note that the character strings determined by these determination formats include those having a single character configuration. In addition, in this embodiment, the counting process is performed in units of characters for these fixed formats. However, the counting process may be performed in units of character strings instead.

“~” In a word indicates a definite form in which a long sound is arranged at an intermediate position and a long sound symbol is replaced with “˜”, and “—” in a word indicates a long sound mark at an intermediate position. Indicates a definite form in which is maintained. “End of word“ ~ ”” indicates a confirmed form in which a long sound is placed at the end and the long sound symbol is replaced with “~”. “End of word“-”” maintains the last long sound. Indicates the confirmed format.
““. ”+ Line feed” indicates a fixed format in which a line break is set after a punctuation is set at the end of the sentence. On the other hand, “New line without“. ”” Indicates a definite form in which a line break is performed without setting a punctuation mark at the end of the sentence.

Next, a detailed procedure of the counting process in step S3 will be described with reference to FIG.
In the first step S101, the preference analysis unit 18 clears the counters for each of the 12 types of confirmed formats to zero, and thereafter pays attention to the clauses classified by the morphological analysis in order from the top (step S102). Check the type and form of words.

  In the example of FIG. 7, first, it is checked whether or not a notable phrase (“−” or “˜”) is included in the currently focused phrase (step S103). If any symbol is present ("YES" in step S103), the symbol is placed at the end or the middle position of the word, or any symbol "~" or "-" is used. And increase the counter value in the definite format that matches the determination result among “End of word“ ~ ””, “End of word“-””, “End of word“-””, and “End of word“-”” (step S104 to S111). In addition, when there are a plurality of notations indicating a long sound in one word, counting is performed for each notation.

  Next, it is checked whether or not a line break code \ n is included in the currently focused phrase (step S112). According to the example of the morphological analysis in FIG. 5, the line break code \ n is set as a phrase delimiter alone. Therefore, when \ n is included in the currently focused phrase (step S112 is “YES”), It is checked whether or not there is a punctuation mark at the end of the previous phrase (step S113). When there is a punctuation (step S113 is “YES”), the counter value ““. ”+ Line feed” is increased, and when no punctuation is set (step S112 is “NO”), “. Increase the counter value of “No line feed”.

  Next, the character type of the currently focused phrase is checked. If the phrase being focused on includes a character string that is unified with any one of katakana, numbers, and alphabetic characters (“YES” in step S116), the character types (alphabetic characters, numbers, The counter value in the definite format corresponding to the type of katakana and whether it is full-width or half-width) is increased (step S117).

  When the above process is executed for all the clauses (“YES” in step S118), the process ends.

  The palatability analysis unit 18 appropriately reads out the mail document stored in the transmission history storage unit of the mail storage unit 8 and executes the processing shown in FIGS. 6 and 7 for each document and analyzes it in units of one month. Statistical processing is performed on the analysis result table accumulated in the result storage unit 7, and the evaluation value of the appearance frequency of the character string in that format is calculated for each determined format. Specifically, for each fixed format, calculate the cumulative value of the appearance frequency in monthly units, multiply each cumulative value by the weighting coefficient set for each month, calculate the sum of these values, and calculate this total value as the evaluation value. And

  FIG. 8 shows an example in which a weighting coefficient for each month is set assuming that an evaluation value is calculated using information for four months. According to this setting, the newer information among the information for four months can be reflected in the evaluation value.

  FIG. 9 shows an example of calculating an evaluation value for each fixed format using the weighting coefficient of FIG. 8, and based on the calculation result, input mode, display of candidates including a long clef symbol, call of a punctuation mark, alphanumeric kana conversion candidate An example in which settings related to display are performed is shown in a table format arranged vertically. In the upper table showing an example of calculation of evaluation values, the frequencies for each confirmed format are summarized every month, and the evaluation values calculated using these frequencies and the weighting coefficients shown in FIG. 8 are shown. . In the example of FIG. 9, it is assumed that four months have not elapsed since the use of the smartphone was started, and the evaluation value is calculated from data up to three months ago.

The palatability analysis unit 18 performs the following five item selection processes using the above evaluation values.
(1) Selection of input mode to be switched by the switch key 31 (2) Selection of whether or not to replace a long sound symbol with “˜” when displaying a character string having a structure in which a long sound symbol is arranged at an intermediate position as a candidate (3) Selection of whether or not to replace a long sound symbol with “˜” when a character string having a structure in which a long sound symbol is arranged at the end is displayed as a candidate. (4) For the operation of the character key 30a to which a punctuation mark is assigned. (5) Display order of candidates extracted according to operation of alphanumeric / kana conversion key

For selection of (1), set the combination of “half-width numbers” and “full-width numbers”, the combination of “half-width English letters” and “full-width English letters”, and the combination of “half-width katakana” and “full-width katakana”. The evaluation values are compared for each combination, and the input mode corresponding to the determined format with the higher evaluation value is selected. In the example of FIG. 9, half-width input is selected for numbers, full-width input is selected for English characters, and half-width input is selected for katakana.
As for katakana, when the evaluation value that is dominant is lower than a predetermined threshold value (because there are few katakana inputs), the katakana input mode is excluded from the switching target (FIG. 2B). See example).)

  For the selection of (2), the evaluation value is compared between “~” in the word and “−” in the word, and priority is given to the candidate display corresponding to the higher evaluation value. In the example of FIG. 9, since the evaluation value of “in the word“-”” is higher, the setting that gives priority to the candidate using the long sound symbol at the intermediate position is selected.

  For selection of (3), the evaluation value is compared between “word end“ ˜ ”” and “word end“-””, and priority is given to the display of the candidate corresponding to the higher evaluation value. In the example of FIG. 9, since the frequency of “word end“ ˜ ”” is higher than the frequency of the other, a setting that gives priority to a candidate using “˜” at the end is selected.

  For the selection of (4), the evaluation value is compared between ““. ”+ Line feed” and ““. ”No line feed”, and if the former has a higher evaluation value, Select a setting that places the call order higher. On the other hand, if the evaluation value of “.” Without line feed is higher, select the setting that does not prioritize the call of the punctuation for the key operation (setting that calls other symbols such as “?” And “!” First). . In the example of FIG. 9, since the frequency of “.” Without line feed ”is higher, the setting that does not give priority to the invocation of punctuation is selected.

  For selection of (5), compare the evaluation values of each confirmation format of “half-width numbers”, “full-width numbers”, “half-width English characters”, “full-width English characters”, “half-width katakana”, and “full-width katakana”, and rank them in descending order. do. FIG. 9 shows the finalized formats up to the top three in the ranking. According to this example, in the display of the candidates accompanying the operation of the alphanumeric / kana conversion key, the candidates by half-width katakana are displayed first, the candidates by half-width numbers are displayed next, and then the candidates by full-width English characters are displayed. As set.

  The above selection result is passed to the preference mode setting unit 23, and priority is given to the function corresponding to the confirmed form that has prevailed in the past character input for each of the input mode switching, candidate display, and phrase call-up. Is set. Thereby, for each individual user, a user interface suitable for the preference and habit of the user can be presented, and the convenience of character input operation is enhanced.

  In addition, since the frequency in the latest month is greatly reflected in the evaluation value by the weighting coefficient shown in FIG. 8, if the tendency of the user's character input changes with the passage of time, according to the change Settings can be varied.

  FIG. 10 shows a processing result when one month has elapsed from the analysis processing shown in FIG. 9 and the evaluation value calculation and setting processing is performed again. The thick dotted line frames in FIG. 9 and FIG. 10 indicate the places where the evaluation value ranks and settings vary between the two. According to the information in these frames, in the process after one month shown in FIG. 10, the evaluation value of “half-width numbers”, which was lower than “half-width katakana” last time, exceeds “half-width katakana”. The first and second places in the display order of alphanumeric / kana conversion candidates are switched. In addition, the evaluation value of “~” in the word, which was lower than “—” in the previous time, is higher than “—” in the word. In this case, the setting that prioritizes the candidate that uses “-” is switched to the setting that prioritizes the candidate that uses “˜”.

FIG. 11 shows a procedure of setting processing executed by the palatability analysis unit 18 every month.
In the first step S11, analysis result tables in which dates corresponding to one month from the current time are stored are read, and the frequencies stored in these tables are accumulated for each determined format. Each accumulated value is used in the processing of this time as well as later processing. Therefore, an analysis result table associated with information indicating the month is created based on these accumulated values and stored in the analysis result storage unit 7. The

  In step S12, the cumulative frequency value from one month to four months ago is read from the past monthly analysis result table. In step S13, each frequency cumulative value acquired in steps S11 and S12 is weighted by the coefficient shown in FIG. 8, and an evaluation value is calculated. Note that, as in the example of FIG. 9, when there is a month in which the accumulated frequency value is not stored, the accumulated frequency value of the month is regarded as 0.

In step S14, for each selection item (1) to (5) described above, the evaluation value is compared between the determination formats related to the item, and the function corresponding to the determination format having a high evaluation value is given priority. Select the setting contents. However, in step S14 when the setting designated by the user is registered for the input mode to be switched, the process of selecting the input mode to be switched is skipped.
When selection of setting contents for all selection items is completed, each setting is stored in step S15, and the process is terminated.

  According to the above-described processing of the preference analysis unit 18, while the user selects a confirmation format according to his / her preference and necessity and inputs characters, a confirmation format having a high appearance frequency based on the input history. It is possible to set a state in which a user interface suitable for inputting a character string is presented. This greatly improves the convenience of character input.

The determination format to be analyzed is not limited to the above 12 types. For example, in the process of creating alphanumeric / kana conversion candidates, a character string representing a time and a character string representing a date are also created as candidates based on a number string assembled based on the operated character key. In this case, if a fixed format is set for each form related to time expression and date expression and is set as an analysis target, it is possible to display candidates corresponding to the fixed format with a high frequency of determination at the top.
In addition, with regard to alphabetic candidates, if the confirmation format is set for each of confirmation with uppercase letters, confirmation with lowercase letters, and confirmation with uppercase letters in the first letter and other letters in lowercase, it will be confirmed in the display of alphanumeric conversion candidates. It becomes possible to display candidates corresponding to a fixed format with high frequency at the top.

  Regarding the selection of the input mode to be switched by the switching key 31 (selection item (1)), in the above embodiment, for each number, alphabetic character, and katakana, the finalized evaluation value using full-width characters and the finalized evaluation value using half-width characters are used. And the input mode corresponding to the determined form with the higher evaluation value is selected, but the evaluation value is further compared between numbers, letters, and katakana, and the input mode for the operation of the switching key 31 is compared. You may set the calling order. For example, when this setting is performed in the example of FIG. 10, the half-width numeric input mode is called by the first operation of the switching key 31, the half-width katakana input mode is called by the second operation, and the full-width alphabetic characters are made by the third operation. The mode will be invoked.

  If the confirmation of pictograms is regarded as a single confirmation format and included in the analysis target, the display state of the pictograms and emoticons in the prediction list and conversion list changes according to the degree to which the user determines the pictograms and emoticons. Can be made. Similar settings can be made for emoticons and symbols.

  FIG. 12 shows an example in which the frequency with which pictograms are determined is analyzed and the analysis result is reflected in the candidate display. In the example of FIG. 12A, the display order of the pictographic candidates is increased in the display of the prediction candidate list accompanying the input of the reading character string. In the example of FIG. 12B, the display order of the pictographic candidates is enhanced in the display of the connection candidate list associated with the determination of the character string. As shown in these examples, for users who frequently determine pictograms, the process up to finalizing pictograms can be simplified by making settings so that candidates for pictograms are displayed preferentially. be able to. On the other hand, when the user rarely uses pictograms, the candidate display reflecting the analysis result can prevent pictogram candidates from being displayed at the top.

When the determined form of pictographs, emoticons, and symbols is analyzed, the analysis result may be reflected in the palette display developed in accordance with the operation of the palette call key 32 as shown in FIG.
In the palette display screen in the example of FIG. 13, a tab 300 is set for each type of pictogram, emoticon, and symbol, and one of them is displayed. By displaying the tab 300, an index set on each tab 300 is displayed by an operation. The target tab 300 is switched.

  In this embodiment, confirmation by pictograms, confirmation by emoticons, and confirmation by symbols are used as individual confirmation formats, respectively, and an evaluation value of the appearance frequency within a predetermined period is obtained by the same method as in the previous embodiment. A ranking is assigned to each confirmed format in descending order. When the pallet call key 32 is operated, the tab 300 including the pallet corresponding to the highest-level fixed format is displayed. Further, the arrangement order of the tabs 300 is also associated with the rank.

  In the example of FIG. 13A, since the confirmation by the pictogram is first, the tab 300 for pictogram is displayed according to the operation of the palette call key 32. Further, in this example, the tab 300 is arranged in the order of English letters, symbols, and emoticons in accordance with the fact that the confirmation by the symbol is second and the confirmation by the emoticon is third.

  In the example of FIG. 13B, the emoticon tab 300 is displayed in accordance with the operation of the palette call key 32 because the emoticon determination is first place. Further, in this example, the tab 300 is arranged in the order of the emoticon, the pictogram, and the symbol with the confirmation by the pictogram being the second place and the confirmation by the symbol being the third place.

According to the above setting, the palette that is most likely to be used is preferentially read with respect to the operation of the palette call key 32, so that the frequency of shifting to the input can be increased without performing the palette switching operation. it can. Thereby, the burden of the operation with respect to the pallet display is reduced and the convenience is enhanced.
However, the arrangement order of the tabs 300 may be fixed, and the palette 300 of the character type having a high selection frequency may be set to the palette displayed first in response to the operation of the palette call key 32.

  In the above embodiment, the appearance frequency of the character string in each confirmed format is obtained by analyzing the text data of the transmitted mail document. However, the analysis target is not limited to this, and is stored in the learning dictionary 6. The recorded historical data can also be analyzed.

  Finally, the processing executed by the preference analysis unit 18 in the above embodiment can also be performed as processing by an external system of the character input system. This external system may be set as another system in the information processing apparatus, but can also be set in an external apparatus such as a personal computer. When the system is set as an external device, the sent mail or the information of the learning dictionary 6 is transmitted from the information processing device to the external device and the analysis process is performed. Determines the operation content for display. Then, the determined matter is transmitted to the information processing apparatus, and the setting on the apparatus side is changed. Also, a web server on the Internet can function as an external device.
