  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

<Overall configuration of Japanese input system>
1 indicates a Japanese input system as a whole, and a plurality of user terminals 2 and a server device 4 possessed by a user can communicate with each other via a communication circuit NT such as the Internet.

  In the Japanese input system 1, a derivative database (hereinafter abbreviated as “DB”) and a popularity order DB are supplied from the server device 4 to the user terminal 2 in advance, and the Japanese input status in the user terminal 2 Accordingly, the popularity order DB and the derivative word DB in the server device 4 are updated. The server device 4 supplies the updated popularity order DB and derivative word DB to the user terminal 2, and the popularity order DB and derivative word DB in the user terminal 2 are updated.

  As shown in FIG. 2, in the user terminal 2, a control unit 21 including a central processing unit (CPU), a read only memory (ROM), and a random access memory (RAM) controls the entire user terminal 2. Then, a simple input process, which will be described later, is executed. Since the user terminal 2 is a smartphone, the user terminal 2 includes the call unit 26, but the call unit 26 is not necessarily required.

  As the user terminal 2, various computer terminals such as a smartphone, a personal computer, and a tablet terminal are used. For convenience, the user terminal 2 will be described as a smartphone. Of course, the user terminal 2 may be a tablet terminal or a personal computer terminal. The server device 4 may be a single terminal or a combination of a plurality of terminals, but is assumed to operate as a single device.

  As shown in FIG. 3, in the server device 4, a control unit 41 including a CPU, a ROM, and a RAM controls the entire server device 4 and executes popular point update processing and database update processing described later. It is made like that.

  The storage unit 45 of the server device 4 stores a popularity order DB and a derivative word DB. When the fixed word is supplied from the user terminal 2 via the external interface 43, the control unit 41 updates the popularity order DB and the derivative word DB. The control unit 41 supplies the updated popularity order DB and derivative word DB to the user terminal 2 via the external interface 43.

  When the popularity order DB and the derivative word DB are supplied via the external interface 23, the control unit 21 of the user terminal 2 stores them in the storage unit 25. As a result, the popularity order DB and the derivative word DB are updated. It is preferable that the popular order DB and the derivative DB to be supplied are normally updated only in the normal state, and the whole is supplied as necessary. Further, the transmission of the fixed word and the update of the popularity order DB and the derivative word DB in the user terminal 2 may be performed sequentially, but are preferably performed periodically. For example, the fixed word is stored and stored in the storage unit 25 and transmitted collectively at a rate of about once per hour. You may make it transmit at the time of a fixed amount of fixed words being preserve | saved.

  The same applies to the popularity order DB and the derivative word DB, and the popularity order DB and the derivative word DB are updated by being transmitted to the user terminal 2 at a rate of about once every 1 to 10 days. The update of the popularity order DB and the derivative word DB may be executed in the form of application upload or may be executed in response to a user request. Further, it may be automatically updated at a predetermined time every day by a timer setting, for example. Note that when there is a large change in ranking, only that portion can be updated sequentially (details will be described later).

  In general, Japanese input is performed by Kana input that assigns “Kana” to a key or Romaji input that assigns “Romaji (alphabet)” to a key. When the input key is entered, a list of candidate words is displayed. As shown in FIG. 2, for example, when inputting the characters “Tokyo”, “to, ki, cho, u” = 5 characters for kana input, and “t, o, u, k, y,” for romaji input. o · u ”= 7 characters.

  In this way, it is possible to reduce the number of input characters in Kana input than in Roman input, but in Kana input, 50 characters must be assigned to the keyboard, and the key layout is different from English input. Therefore, the current mainstream is romaji input.

  Here, as shown in FIG. 4, when the hiragana initial input is performed to input only the initials of the hiragana characters in the “TOKYO” hiragana notation, the number of inputs is reduced to “t · u · k · u” = 4 characters. be able to. Furthermore, in the first Roman letter input that omits vowels other than the first letter, three letters “t, y, o”, and in the first simple Roman letter entry that omits the lower case of stuttering in the first Roman letter input, and “Tokyo” in Kanji notation It is considered that the number of inputs can be reduced to two characters “t · k” and the user's input operation can be simplified.

  Therefore, in the Japanese input system of the present invention, these multiple input methods (Romaji input, first Romaji input, first Romaji input and Kanji first Romaji input: these are summarized below, based on keyboard character assignment by Romaji input. This is called “Romaji mixed input”.

  However, as shown in FIG. 5, a total of 32,400 combinations of all hiragana characters such as five types of vowels, prompt sounds, long sounds, and the possibility of stuttering will occur. That is, too many candidate words are displayed, and there is a possibility that the user's input operation becomes complicated.

  Therefore, in the Japanese input system of the present invention, the following methods 1) to 3) are executed to increase the probability of displaying the candidate word intended by the user.

  1) A confirmed word that is finalized for use by a user is preferentially displayed as a candidate word. The priority order of the candidate words is constantly updated in the Japanese input system 1.

  2) A derivative word associated with a group of derivative words whose meanings are almost the same but differ depending on the usage or abbreviation is registered as a derivative word DB, and a list of derivative words is obtained when the user operates the candidate word. A derivative word list is displayed and the user can select from the derivative word list. For example, in the case of having an inflected form such as a verb or adjective, or “a happy new year” = “ame”, or a phrase added with a particle corresponds to a derivative word.

  As shown in FIG. 6, for example, when “A · R · K” is input, there are 145,800 combinations of kana. When the user selects “walking”, a derivative word list of “walking” is displayed by pull-down as shown in FIG. Thereby, the user can select a candidate word to be input from the derived word list.

  As shown in FIG. 8, when “T • Y” is input as “sun”, there are many homonyms such as “mode”, “endurance”, “ocean”, “taiyo”, etc. There are many words expressed as “T • Y” such as “promotion”, “Toyo”, and “theft”. In this case, as shown in FIG. 9, when the user selects “sun”, a word in which a particle is added after “sun” is displayed by pull-down as a derived word list of “sun”.

  3) When the candidate word that the user wants to input is difficult to display, the user can add Roman characters later or from the beginning.

  As shown in FIG. 10, if you want to enter “Tokyo”, add vowels and stuttering after “T · K” to “Y · O · Y”, so that you can make 90 combinations. This can reduce the probability that the candidate word intended by the user is displayed.

  Also, as shown in FIG. 11, when inputting “Tokyo”, the combination of kana can be reduced to 360 by inputting Roman characters from the beginning.

<Popular point update processing>
Next, popular point update processing will be described.

  The storage unit 45 of the server device 4 stores three databases: a point DB, a popularity order DB, and a derivative word DB.

  As shown in FIG. 12, the point DB is a database that manages popular points, and is registered in association with word IDs, conversion words that may be displayed as candidate words, and popular points. The popular points are totaled every predetermined time (for example, 24 hours), and the total of the popular points added in the latest seven days is used as the popular points.

  As shown in FIG. 13, in the popularity order DB, the input key, the non-converted word, the word ID associated with the input key, and the ranking of the word ID in the popularity point order are registered.

As shown in FIG. 14, the derivative DB has the same or almost the same meaning as the group ID (indicated by GP in the figure), but uses expressions such as inflection forms, abbreviations, and differences in particles and endings. The word IDs of the different derived words are registered. In this derivative word DB, not only the derivative words are associated but also ranking within the group according to popularity points.

  Here, as described above, in the Japanese input system, it is possible to input using the Roman character mixed input method. As shown in FIG. 15, for example, the conversion word “Tomorrow” has two readings “Tomorrow” and “Tomorrow”. In this case, when inputting the first Roman letter of “Ashita”, “A · S · T” is input as the first Roman character input key, and “A” and “A · S” are also input keys in order from the front. In addition, “A · S · T” with vowels added from the back, “A · S · I · T” and “A · S · I · T · A” with Romaji input from the front are also registered as input keys. ing.

  In addition, when inputting the first Roman letter of “ASU”, “A · S” is input, and “A” is also an input key in order from the front. Furthermore, “A · S · U”, which is a vowel added from the rear (the same is applied to Roman characters), is also registered as an input key.

  That is, for the conversion word “Tomorrow”, “A” “A · S” “A · S · T” “A · S · T” “A · S · I · T” “A · S · I · T” -A total of seven "A", "A, S, U" are registered as input keys.

  Also, as shown in FIG. 16, for the conversion word “zoo”, “D · U · B · T · E · N” is input as the first Romaji input key in the case of the first Romaji input of “Animal”. “D”, “D • U”, “D • U • B”, “D • U • B • T”, “D • U • B • T • E” are also input keys in order from the front. In addition, in the case of inputting the first simple Roman character, “D · B · T · E” is input as the first simple input key, and “D · B” and “D · B · T” are also input keys. Furthermore, "D, B, T, E, N", "D, B, T, U, E", "D, U, B, T, U, E, N", "D, U," added vowels from the rear. B / T / E / N ”, Romaji input keys for Romaji input from the front,“ D • O ”“ D • O • U ”“ D • O • U • B ”“ D • O • U • B • U ” "" D.O.U.B.U.T "" D.O.U.B.U.T.U "" D.O.U.B.U.T.U.E "" D.O " "U, B, U, T, U, E, N" are also registered as input keys. Also, “D · B · E” and “D · B · E · N” added with vowels from the back are registered as kanji start input keys for Kanji start input.

  That is, for the conversion word “zoo”, a total of 22 is registered as an input key.

  Accordingly, the word ID of the conversion word is associated with all the corresponding input keys in the popularity order DB (see FIG. 13).

  The control unit 41 of the server device 4 updates the popular points in the point DB based on the confirmed word supplied from the user terminal 2.

  For example, as shown in FIG. 17 (A), when the character string “let's go to the zoo tomorrow!” Is supplied from the user terminal 2 as the confirmed word, the control unit 41 displays the word in FIG. 17 (B). As shown, first, a character string is divided into phrases by distinguishing punctuation marks and particles. In this case, it is divided into three clauses: “Tomorrow,” “Go to the zoo” and “Let's go!”.

  Next, the control unit 41 separates a word part to which a popularity point should be given for each phrase and an additional part such as a particle or ending. And the control part 41 adds a popular point with respect to the corresponding conversion word in point DB about two types of conversion words of a word part and a word part + addition part.

  As described above, the control unit 41 of the server device 4 adds a popularity point for each conversion word based on the confirmed word supplied from the user terminal 2.

  Note that if the conversion word extracted from the confirmed word does not exist in the point DB, the control unit 41 newly registers the extracted conversion word in the point DB. When the number of popular points exceeds a predetermined registration threshold, a new conversion word is registered in the popularity order DB and the derivative word DB. Thereby, when a new word is frequently used, the new word can be automatically registered in the popularity order DB and the derivative word DB as a conversion word.

  Moreover, the control part 41 performs a database update process regularly by reviewing the ranking in popularity order DB and derivative word DB regularly (for example, every 30 minutes). Of course, this processing may be executed every time for all the conversion words, but if it is executed for all the conversion words, the processing load is heavy, so that only the conversion words with a high number of popular points are usually targeted. The whole may be calculated in a time zone in which the supply of the fixed word decreases (for example, midnight to 2:00 to 5:00). At this time, you may make it register the new word in which the popular point mentioned above exceeded the registration threshold value.

  At this time, in the popularity order DB, the control unit 41 registers only one conversion word to which the same group ID is added in the derivative word DB in the popularity order DB. This prevents a plurality of derived words having the same group ID from being registered in the upper level.

  As described above, in the server device 4, the rank in the popularity order DB and the derivative word DB is updated according to the use (confirmation) status of the conversion word in the user terminal 2.

<Simple input process on user terminal>
As described above, the popularity order DB and the derivative word DB are supplied from the server device 4 to the user terminal 2. The popularity order DB and derivative term DB supplied from the server device 4 may be all, but only the high-ranked part considering the processing load and communication load in the user terminal 2 (for example, the top 20 in the popularity order DB) Or the top 10 in the derivative DB) may be supplied.

  The control unit 21 of the user terminal 2 executes a simple input process based on the supplied popularity order DB and derivative word DB. The display unit 24 displays an input display field 51 in which input characters are displayed and a keyboard 50. And the control part 21 displays the candidate word list 52 which is a list of candidate words according to operation with respect to the operation input part 27 of a user.

  For example, as shown in FIG. 18, when “A” is input as an input key, the control unit 21 displays a candidate word list 52 in which candidate words are displayed in order of popularity in the popularity order DB. “Tomorrow” is displayed second because it is second in order of popularity. When the user places his / her finger on “Tomorrow”, the derived word list 54 is displayed in a pull-down manner. The derivative word list 54 displays derivative words belonging to the same group in the derivative word DB in order of popularity. When the user taps “tomorrow,” in the derived word list 54, “tomorrow,” is confirmed.

  Subsequently, as shown in FIG. 19, when “D, B, T” is input as an input key, the control unit 21 displays candidate words in the popularity order in the popularity order DB. “Zoo” is the second most popular and is displayed second. When the user places his / her finger on “zoo”, the derived word list is displayed in a pull-down manner. The derivative word list displays derivative words belonging to the same group of the derivative word DB in order of popularity. When the user taps “to zoo” in the derived word list, “to zoo” is confirmed.

  Furthermore, as shown in FIG. 20, when “I · K” is input as an input key, the control unit 21 displays candidate words in the popularity order in the popularity order DB. “Go” is displayed as the most popular candidate word. When the user operates “go”, the derived word list is displayed in a pull-down manner. If the derived word list 54 cannot be displayed, a down arrow 55 is displayed at the bottom. When the user taps the down arrow 55, as shown in FIG. 21, the keyboard 50 is not displayed, and instead, a derived word full list 56, which is a full list of derived words, is displayed.

  When the user taps “Let's go!” From the list of all derived words 56, “Let's go!” Is confirmed. When the up arrow 57 displayed at the lower right of the derived term all list 56 is selected, the screen returns to the previous screen (FIG. 20). When the down arrow 53 on the right side of the candidate word list 52 is selected, a candidate word full list (not shown), which is a full list of candidate words, is displayed. Since the candidate word full list is the same as the derived word full list 56 except that the candidate words are displayed in a list, the description thereof will be omitted.

  Although not shown, as described above, the input can be performed in the same manner by any of the normal Roman character input, Chinese character leading input, and leading Roman character input.

  In this way, the user terminal 2 allows the user to input Japanese by using a Roman character mixed input method. At this time, by displaying only one derivative word in the candidate word list 52, there are not too many candidate words. Further, since the user completes the input simply by selecting from the candidate word list 52 or the derived word list 54, the number of input characters can be significantly reduced.

<Simple input processing procedure>
Next, the simple input process S100 executed according to the simple input program will be described with reference to the flowchart of FIG.

  When the user prepares for character input by opening a character input screen, for example, the user terminal 2 starts a simple input process in step S100, and proceeds to the next step S101.

  In step S101, when the user inputs a character, the process proceeds to the next step S102, the popular DB is searched using the input uncertain character as an input key, and the process proceeds to the next step S103. In step S103, the control unit 21 causes the candidate words to be displayed on the candidate word list 52 in the display unit 24 in descending order of the conversion words corresponding to the input keys, and proceeds to the next step S105.

  In step S105, the control unit 21 determines whether or not a display request for a derivative word in the candidate word has been made by the user. If a negative result is obtained here, the process proceeds to the next step S108. On the other hand, if an affirmative result is obtained in step S105, this means that a derivative word is requested, so the control unit 21 proceeds to the next step S106.

  In step S106, the control unit 21 searches the derivative word DB, identifies a derivative word group having a corresponding conversion word, and proceeds to the next step S107. In step S107, when the control unit 21 displays a list of derivative words belonging to the specified group in the order of popularity, the control unit 21 proceeds to the next step S108.

  In step S108, when the control unit 21 recognizes that a candidate word has been designated, the control unit 21 proceeds to the next step S109. In step S109, the control unit 21 confirms the candidate word designated by the user as a confirmed word, and repeats the procedure from step S101.

  As described above, the control unit 21 of the user terminal 2 displays the candidate words using the popularity order DB and the derivative word DB, and allows the user to select the candidate words.

<Invention extracted from the above embodiment>
Hereinafter, the characteristics of the invention group extracted from the above-described embodiment will be described while showing problems and effects as necessary. In the following, for easy understanding, the corresponding configuration in each of the above embodiments is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses. In addition, the meanings and examples of terms described in each feature may be applied as the meanings and examples of terms described in other features described in the same wording.

The terminal device (user terminal 2) of the present invention includes an operation unit (operation input unit 27) in which an input key is input by a user operation input,
A display unit (display unit 24) on which the input key is displayed;
A storage unit (storage unit 25) for storing a popularity order database in which the conversion word and the popularity order of the conversion word are associated with the input key;
A candidate word selection unit (control unit 21) that, when an input key is input, displays conversion words selected in descending order of popularity from the popularity order database as candidate words on the display unit;
In the popularity database,
As the input key, when the conversion word is written in romaji, a first romaji key in which only the first romaji that becomes the first part of kana is extracted, or a first simple romaji key that omits vowels other than the first from the first romaji key At least one of them is registered. The first Roman key and the first simple Roman key may be registered in all conversion words, or may be registered only in a specific part of speech (for example, a noun). It is preferably registered at a rate of 20% or more with respect to all conversion words.

  Thus, it is possible to input a character string with a small number of characters by inputting the first Roman character using the first Roman character key or inputting the first simple Roman character using the first simple Roman character key.

  The terminal device is characterized in that a normal Romaji key in which the conversion word is written in Romaji is registered as the input key. Thus, even when an appropriate candidate word is not displayed by the first Roman key and the first simple Roman key, it is sufficient to input the normal Roman character, and the user's input operation can be simplified.

The terminal device uses the input key as
When the conversion word is written in Roman characters, a Kanji first Roman key extracted from only the first Kanji character that becomes the first portion of the Kanji character is registered.

  Thereby, the number of characters input by the user can be further reduced, and the user's input operation can be simplified.

  The Kanji leading Roman key is registered only for nouns. In particular, nouns are not useful, and are suitable for inputting Kanji first Roman characters. Kanji head Roman input can reduce the number of inputs, but the number of combinations of kana is enormous. Therefore, by limiting to only nouns, it is possible to easily generate candidate words intended by the user.

In the storage unit in the terminal device,
Derived word database is registered, which is a group of derived words, which are converted words that have the same meaning but are expressed differently depending on usage and abbreviation.
The candidate word selector is
Select only one candidate word from each derivative word group,
When a candidate word selected from the derivative word group is operated, a derivative word list which is a list of derivative words registered in the derivative word group is displayed as a list.

  In the first Roman alphabet input and the first simple Roman alphabet input, although the number of inputs can be reduced, the number of combinations of kana increases and the number of candidate words also increases. Therefore, the rank of candidate words that the user wants to input can be increased by grouping derivative words and displaying only one.

In the terminal device, the derivative word database is:
Ranking the derivative terms within the derivative group,
The derivative word list is displayed according to the ranking.

  Thereby, derivative words can also be displayed according to the order, and the user can easily select candidate words.

Further, in the Japanese input system (Japanese input system 1) of the present invention, the conversion word and the popularity order of the conversion word are associated with the input key, and the conversion word is expressed in Roman letters as the input key. Sometimes, at least one of the first Romaji key that extracts only the first Romaji, which is the first part of kana, or the first simple Romaji key that omits the vowel other than the first one from the first Romaji key is registered. A storage unit for storing a sequential database;
A popular point adding unit (control unit 41) for adding a popular point to the converted word corresponding to the fixed word based on the supplied fixed word (storage unit 45);
A server device (server device 4) having a database update unit (control unit 41) for updating the popularity order in the popularity order database based on the popularity points;
An operation unit in which an input key is input by a user operation input;
A display unit on which the input key is displayed;
A storage unit that is supplied from the server device and stores the popularity order database;
When an input key is entered, a candidate word selection unit that causes the display unit to display conversion words selected in descending order of popularity from the popularity order database as candidate words;
And a terminal device having a transmission unit that transmits the confirmed word to the server device.

  Thereby, in a Japanese input system, since a popularity order database can always be updated based on a fixed word, the probability that the user's intended candidate word will be displayed can be raised. It is also possible to deal with trends and seasonal words.

In the Japanese input system, the popular point adding unit in the server device is:
The definite word is divided into phrases, the word and the added part are separated from the phrase, and the popularity points are added to both the word-only converted word and the converted word as the phrase.

  Thereby, in a Japanese input system, the popularity point about only a word can be inevitably raised and displayed as a candidate word, and a candidate word can be efficiently displayed in a small space.

In the Japanese input system, the server device
When the conversion word based on the fixed word is new,
The conversion word is stored as a new word, and is registered in the popularity order database when the popularity point reaches a predetermined number or more.

  As a result, new buzzwords and the like can be quickly reflected in the popularity order database while preventing an erroneously input word from being registered.

According to the above configuration, in the terminal device, the operation unit in which the input key is input by the user's operation input,
A display unit on which the input key is displayed;
A derivative word that is a converted word whose meaning is the same as that of the popularity order database in which the conversion word and the popularity order of the conversion word are associated with the input key but whose expression is different depending on the utilization form or abbreviation is used as a derivative word group. A storage unit for storing a grouped derivative database;
When the input key is input, when displaying the conversion words selected in the descending order of popularity from the popularity order database on the display unit as candidate words, only one from each derivative word group is selected as the candidate word,
When a candidate word selected from the derivative word group is operated, a derivative word list which is a list of derivative words registered in the derivative word group is displayed as a list.

  Thereby, since only one candidate word is displayed in the derived word group, candidate words having the same meaning are not displayed in succession, and the candidate word intended by the user can be easily displayed.

<Other embodiments>
In the above-described embodiment, a character string composed of sentences is supplied as a fixed word, but the present invention is not limited to this. For example, the confirmed word to be supplied may be a confirmed word string such as a word, a word + an ending, or a particle that is confirmed by actually being selected once at the user terminal, or may be a phrase unit.

  In the above-described embodiment, the popularity points are added to both the word and the confirmed character string. However, the popularity points may be added only to the confirmed word (the confirmed character string). Moreover, although the popular point was totaled every day, it may be set every 3 hours, for example, or may be a total from the start.

  In the above-described embodiment, the server apparatus 4 has the point DB, the popularity order DB, and the derivative word DB, but there is no limitation on the configuration of the database. For example, you may have the database which united the function of point DB and popularity order DB. Further, in the Japanese input system 1, the derivative word DB is not essential, and at least one of the popularity order DB and the derivative word DB is sufficient.

  In the above-described embodiment, the derived words are displayed according to the ranking by popularity points. However, for example, a basic word may be provided in the derived word DB, and the basic word may always be displayed as a candidate word. In addition, candidate words in which derivative words exist may be marked and displayed, or may be displayed with different colors.

  In the embodiment described above, the user terminal 2 simply displays the candidate words only in the popularity order of the popularity order DB, but the history for each user may be mixed and used. For example, the user has his / her own history DB, weights the popularity order DB, stores a favorite expression and preferentially displays it, or displays a predetermined number of candidate words (one or more) from the recent history. Only two) can be preferentially displayed.

  In the above-described embodiment, it is possible to input any of the first Roman alphabet input, the first simple Roman alphabet input, and the Roman alphabet input. However, only one of the first Roman alphabet input and the first simple Roman alphabet input may be used. It may be possible to input only the first part (only popular ones or only conversion words that match a specific part of speech or condition) and input the first Roman letter. A part means at least 20% or more of the entire conversion word. Further, it may be recognized whether the first Roman alphabet input, the first simple Roman alphabet input, or the Roman alphabet input is input. For example, it is determined whether or not the input method is Roman character input based on whether or not a vowel is input at the second character (the third character when the first character is a vowel). An identifier that can be used to identify which input method is used in advance is added to the input key, and when it is determined that the input is romaji, a search is performed preferentially from the input key of the romaji input method by the identifier, Romaji input is given priority and displayed in the candidate word.

  In the above-described embodiment, the derivation words having different endings are displayed as candidate words, but the derivation words and endings may be separated. For example, as a derived word list, candidate words in which only the utilization form is changed and only the endings are simultaneously displayed as separate lists, and candidate words and endings are selected from each list. Further, it is also possible to select only the utilization form from the changed derived word list, and then automatically display the ending as a candidate word for selection. As a result, the number of conversion words can be reduced by the number of combinations at the end of the word, and selection of candidate words can be facilitated.

  The present invention can be applied to a Japanese input program that performs Japanese input using a personal computer that can be a smartphone, for example.
