Description

変換候補調整ユニット、サーバ、文字入力装置、文字変換システム、変換候補調整方法、および変換候補調整プログラムConversion candidate adjustment unit, server, character input device, character conversion system, conversion candidate adjustment method, and conversion candidate adjustment program
　この発明は、入力された文字列に対する変換候補の並びを調整する技術に関する。 The present invention relates to a technique for adjusting the arrangement of conversion candidates for an input character string.
　従来、文字入力が行える電子機器は、ユーザの入力操作によって入力された文字列に対する変換候補を抽出する。電子機器は、抽出した変換候補を、最近の選択結果や過去に選択された頻度等に基づいて表示する順番を調整する。電子機器は、ユーザによって選択された変換候補を、入力された文字列に対する確定文字列に確定する。このように構成された、電子機器においては、ユーザが所望する確定文字列の変換候補が上位に表示されるほど、ユーザが所望の確定文字列を変換候補の中から見つけやすくなる。したがって、文字入力が行える電子機器は、ユーザが所望する確定文字列の変換候補を上位に表示することによって、ユーザの操作性の向上が図れる。 Conventionally, an electronic device capable of inputting characters extracts conversion candidates for a character string input by a user's input operation. The electronic device adjusts the order in which the extracted conversion candidates are displayed based on the recent selection result, the frequency selected in the past, and the like. The electronic device determines the conversion candidate selected by the user as a confirmed character string for the input character string. In the electronic device configured in this way, the higher the conversion candidate of the definite character string desired by the user is displayed, the easier it is for the user to find the desired definite character string from the conversion candidates. Therefore, the electronic device capable of inputting characters can improve the operability of the user by displaying the conversion candidates of the definite character string desired by the user at the higher level.
　また、ユーザの操作性の向上を図る目的で、変換候補の並びを、入力状況に応じて調整する構成のものがあった（特許文献１参照）。ここで言う入力状況とは、文字入力が実行されている時期、作成中の文章の表現形式、装置における入力モード等である。 Further, for the purpose of improving the operability of the user, there was a configuration in which the arrangement of conversion candidates was adjusted according to the input status (see Patent Document 1). The input status referred to here is the time when character input is being executed, the expression format of the text being created, the input mode in the device, and the like.
特開２００９－２７６８１８号公報Japanese Unexamined Patent Publication No. 2009-276818
　しかしながら、特許文献１等に記載された従来の技術は、言語の属性に応じて変換候補の並びを調整するものではなかった。ここで言う言語の属性とは、方言の種類、技術分野の種類、ネット用語等である。方言の種類は、例えば、関西弁、津軽弁、広島弁に細分類される。また、技術分野の種類は、例えばＩＴ技術、医療技術、土木技術に細分類される。このため、ユーザが、普段使用している属性の言語であっても、あまり入力していない文字列（初めて入力する文字列を含む。）については、対応する変換候補を上位に表示することができず、ユーザの操作性を低下させることがあった。 However, the conventional technique described in Patent Document 1 and the like does not adjust the arrangement of conversion candidates according to the attributes of the language. The language attributes referred to here are dialect types, technical field types, Internet slang, and the like. The types of dialects are subdivided into, for example, Kansai dialect, Tsugaru dialect, and Hiroshima dialect. The types of technical fields are subdivided into, for example, IT technology, medical technology, and civil engineering technology. For this reason, even if the language of the attribute that the user normally uses, the corresponding conversion candidate may be displayed at the top for the character string that is not input much (including the character string that is input for the first time). It could not be done, and the operability of the user was sometimes deteriorated.
　この発明の目的は、ユーザが普段使用している言語の属性に応じて変換候補を並べることで、文字入力におけるユーザの操作性を向上させる技術を提供することにある。 An object of the present invention is to provide a technique for improving the user's operability in character input by arranging conversion candidates according to the attributes of the language that the user usually uses.
　この発明の変換候補調整ユニットは、上記目的を達成するため以下に示すように構成している。 The conversion candidate adjustment unit of the present invention is configured as shown below in order to achieve the above object.
　変換候補取得部は、入力された文字列の変換候補を取得する。確定文字列取得部は、入力された文字列に対して確定された確定文字列を取得する。推定部は、確定文字列の言語の属性に応じて、属性別に優先度を推定する。ここで言う言語の属性とは、方言の種類、技術分野の種類、ネット用語等である。方言の種類は、例えば、関西弁、津軽弁、広島弁に細分類される。また、技術分野の種類は、例えば、ＩＴ技術、医療技術、土木技術に細分類される。 The conversion candidate acquisition unit acquires conversion candidates for the input character string. The fixed character string acquisition unit acquires a fixed character string confirmed for the input character string. The estimation unit estimates the priority for each attribute according to the language attribute of the fixed character string. The language attributes referred to here are dialect types, technical field types, Internet slang, and the like. The types of dialects are subdivided into, for example, Kansai dialect, Tsugaru dialect, and Hiroshima dialect. Further, the types of technical fields are subdivided into, for example, IT technology, medical technology, and civil engineering technology.
　そして、調整部が、推定部による属性別の優先度の推定結果に基づいて、変換候補取得部が取得した変換候補を並べる。 Then, the adjustment unit arranges the conversion candidates acquired by the conversion candidate acquisition unit based on the estimation result of the priority for each attribute by the estimation unit.
　この構成によれば、ユーザが普段使用している言語の属性に応じて変換候補を並べることができる。例えば、ユーザが普段使用している言語の属性が関西弁であれば、関西弁にかかる文字列の変換候補を上位に表示させることができる。また、ユーザが普段使用している言語の属性がＩＴ技術であれば、ＩＴ技術にかかる文字列の変換候補を上位に表示させることができる。 According to this configuration, conversion candidates can be arranged according to the attributes of the language that the user usually uses. For example, if the attribute of the language that the user usually uses is the Kansai dialect, the conversion candidates of the character string related to the Kansai dialect can be displayed at the higher level. Further, if the attribute of the language that the user usually uses is IT technology, the conversion candidate of the character string related to IT technology can be displayed at the higher level.
　このように、ユーザが入力した文字列に対して、ユーザが普段使用している属性の変換候補を上位に表示させることができる。特に、ユーザがこれまであまり入力していない文字列（初めて入力する文字列を含む。）であっても、ユーザが普段使用している属性の変換候補を上位に表示させることができる。したがって、文字入力におけるユーザの操作性の向上が図れる。 In this way, it is possible to display the conversion candidates of the attributes normally used by the user at the higher level for the character string input by the user. In particular, even if the character string has not been input by the user so far (including the character string input for the first time), the conversion candidates of the attributes normally used by the user can be displayed at the higher level. Therefore, it is possible to improve the user's operability in character input.
　また、例えば、確定文字列を属性別に集計する集計部を備え、
　推定部は、集計部の集計結果を用いて、言語の属性に対する優先度を推定する構成にしてもよい。 In addition, for example, it is provided with a totaling unit that aggregates fixed character strings by attribute.
The estimation unit may be configured to estimate the priority for the language attribute by using the aggregation result of the aggregation unit.
　この構成によれば、確定文字列を属性別に集計するので、ユーザが文字入力において、使用している言語の属性を効率的に集計できる。 According to this configuration, since the fixed character string is aggregated by attribute, the attribute of the language used by the user can be efficiently aggregated in the character input.
　また、変換候補調整ユニットは、ユーザが文字列の入力操作を行う文字入力装置と通信できるサーバに設けてもよいし、ユーザが文字列の入力操作を行う文字入力装置に設けてもよい。 Further, the conversion candidate adjustment unit may be provided in a server capable of communicating with a character input device in which the user performs a character string input operation, or may be provided in a character input device in which the user performs a character string input operation.
　例えば、変換候補調整ユニットをサーバに設ける場合、このサーバには、インタネット等のネットワークを介して文字入力装置と通信する第１通信部が備えられる。この場合、サーバは、第１通信部における文字入力装置との通信で、文字入力装置においてユーザが入力した文字列に対する変換候補を取得する構成であってもよいし、文字入力装置においてユーザが入力した文字列を取得する構成であってもよい。 For example, when a conversion candidate adjustment unit is provided in a server, this server is provided with a first communication unit that communicates with a character input device via a network such as the Internet. In this case, the server may be configured to acquire conversion candidates for the character string input by the user in the character input device in communication with the character input device in the first communication unit, or may be input by the user in the character input device. It may be configured to acquire the character string.
　サーバが、第１通信部における文字入力装置との通信で、文字入力装置においてユーザが入力した文字列に対する変換候補を取得する構成である場合、ユーザが入力した文字列に対する変換候補を抽出する構成を文字入力装置に設ければよい。また、サーバが、第１通信部における文字入力装置との通信で、文字入力装置においてユーザが入力した文字列を取得する構成である場合、変換候補取得部が、文字入力装置においてユーザが入力した文字列に対する変換候補を取得すればよい。 When the server is configured to acquire conversion candidates for the character string input by the user in the character input device in communication with the character input device in the first communication unit, the configuration is to extract conversion candidates for the character string input by the user. May be provided in the character input device. Further, when the server is configured to acquire the character string input by the user in the character input device by communicating with the character input device in the first communication unit, the conversion candidate acquisition unit is input by the user in the character input device. All you have to do is get the conversion candidates for the character string.
　また、サーバは、調整部により調整された変換候補の並びを、第１通信部で文字入力装置に送信する構成にすればよい。 Further, the server may be configured to transmit the sequence of conversion candidates adjusted by the adjustment unit to the character input device in the first communication unit.
　また、変換候補調整ユニットを、サーバではなく、文字列の入力にかかる操作を受け付ける操作部を備える文字入力装置に設ける場合、変換候補取得部を、ユーザが入力した文字列に対する変換候補を取得する構成にすればよい。 Further, when the conversion candidate adjustment unit is provided not in the server but in a character input device provided with an operation unit for receiving an operation related to the input of a character string, the conversion candidate acquisition unit acquires conversion candidates for the character string input by the user. It may be configured.
　また、文字入力装置は、例えば、変換候補を、調整部により調整された並びで表示部に表示する構成にすればよい。 Further, the character input device may be configured to display conversion candidates on the display unit in an arrangement adjusted by the adjustment unit, for example.
　この発明によれば、ユーザが普段使用している言語の属性に応じて変換候補を並べることで、文字入力におけるユーザの操作性を向上させることができる。 According to the present invention, it is possible to improve the user's operability in character input by arranging conversion candidates according to the attributes of the language that the user usually uses.

　以下、この発明の実施形態について説明する。 Hereinafter, embodiments of the present invention will be described.
　＜１．適用例＞
　図１は、この例にかかる文字変換システムを示す図である。この例の文字変換システム１００は、携帯端末１と、サーバ２とがインタネット等のネットワーク２００を介してデータ通信可能に接続されている。携帯端末１は、ユーザが文字列の入力操作を行う端末である。携帯端末１は、例えばスマートフォン、タブレット端末である。この例では、携帯端末１が、この発明で言う文字入力装置に相当する。また、この例では、サーバ２が、この発明の実施形態にかかる変換候補調整ユニットを備えている。 <1. Application example>
FIG. 1 is a diagram showing a character conversion system according to this example. In the character conversion system 100 of this example, the mobile terminal 1 and the server 2 are connected to each other via a network 200 such as an Internet so that data communication is possible. The mobile terminal 1 is a terminal in which a user performs a character string input operation. The mobile terminal 1 is, for example, a smartphone or a tablet terminal. In this example, the mobile terminal 1 corresponds to the character input device referred to in the present invention. Further, in this example, the server 2 includes a conversion candidate adjustment unit according to the embodiment of the present invention.
　文字列の入力には、公知のように、言語の種類によって、文字列として入力したい言葉（所望の文字列）の発音表記をユーザに入力させる方式と、文字列として入力したい言葉のスペルをユーザに入力させる方式がある。例えば、日本語、中国語が、文字列として入力したい言葉の発音表記（読み（かな）、ピンイン）をユーザに入力させる方式である種類の言語である。また、例えば、英語、ドイツ語が、文字列として入力したい言葉のスペルをユーザに入力させる方式である種類の言語である。 For character string input, as is well known, depending on the type of language, the method of having the user input the pronunciation notation of the word (desired character string) to be input as a character string and the spelling of the word to be input as a character string are used by the user. There is a method to input to. For example, Japanese and Chinese are a kind of language in which the user is required to input the pronunciation notation (reading (kana), pinyin) of the word to be input as a character string. Further, for example, English and German are a kind of language in which the user is made to input the spelling of the word to be input as a character string.
　ここでは、日本語の文字変換システムを例にして説明する。すなわち、この例では、ユーザは、文字列として入力したい言葉（所望の文字列）の発音表記（読み文字列）を入力する操作を携帯端末１で行う。この例では、読み文字列が、この発明で言う文字列に相当する。 Here, a Japanese character conversion system will be used as an example for explanation. That is, in this example, the user performs an operation of inputting a pronunciation notation (reading character string) of a word (desired character string) to be input as a character string on the mobile terminal 1. In this example, the reading character string corresponds to the character string referred to in the present invention.
　この例では、ユーザが携帯端末１において、読み文字列を入力する操作を行う。図２は、文字入力処理時における携帯端末の画面の表示例を示す図である。携帯端末１（この例では、スマートフォン）は、表示器５１の画面にタッチパネル５２が貼付されている。文字入力処理時における表示器５１の画面には、文字キー表示領域６０、読み文字列表示領域６１、および変換候補表示領域６２が表示される。文字キー表示領域６０には、文字入力時に操作する複数の文字キーが表示される。読み文字列表示領域６１には、ユーザが文字キーを操作して入力した読み文字列が表示される。変換候補表示領域６２には、読み文字列表示領域６１に表示されている読み文字列に対する変換候補が表示される。 In this example, the user performs an operation of inputting a reading character string on the mobile terminal 1. FIG. 2 is a diagram showing a display example of a screen of a mobile terminal during character input processing. In the mobile terminal 1 (smartphone in this example), the touch panel 52 is attached to the screen of the display 51. On the screen of the display 51 at the time of character input processing, a character key display area 60, a reading character string display area 61, and a conversion candidate display area 62 are displayed. In the character key display area 60, a plurality of character keys to be operated at the time of character input are displayed. In the reading character string display area 61, the reading character string input by the user by operating the character key is displayed. In the conversion candidate display area 62, conversion candidates for the reading character string displayed in the reading character string display area 61 are displayed.
　この例では、携帯端末１は、内蔵している辞書を用いて、入力された読み文字列に対する変換候補を抽出する。携帯端末１は、自端末を識別する識別コードとともに、抽出した変換候補をサーバ２に送信する。携帯端末１は、例えば変換候補を抽出した順番に並べてサーバ２に送信する。 In this example, the mobile terminal 1 uses the built-in dictionary to extract conversion candidates for the input reading character string. The mobile terminal 1 transmits the extracted conversion candidates to the server 2 together with the identification code for identifying the own terminal. For example, the mobile terminal 1 arranges conversion candidates in the order in which they are extracted and transmits them to the server 2.
　サーバ２は、携帯端末１の識別コードと、その携帯端末１について推定した言語の属性別の優先度とを対応付けて記憶している。ここで言う言語の属性とは、方言の種類、技術分野の種類、ネット用語等である。方言の種類は、例えば、関西弁、津軽弁、広島弁に細分類される。また、技術分野の種類は、例えば、ＩＴ技術、医療技術、土木技術に細分類される。 The server 2 stores the identification code of the mobile terminal 1 in association with the priority of each language attribute estimated for the mobile terminal 1. The language attributes referred to here are dialect types, technical field types, Internet slang, and the like. The types of dialects are subdivided into, for example, Kansai dialect, Tsugaru dialect, and Hiroshima dialect. Further, the types of technical fields are subdivided into, for example, IT technology, medical technology, and civil engineering technology.
　サーバ２は、携帯端末１から送信されてきた変換候補の並びを、当該携帯端末１について記憶している言語の属性別の優先度に基づいて調整する。サーバ２は、変換候補を調整した並びで携帯端末１に返信する。 The server 2 adjusts the sequence of conversion candidates transmitted from the mobile terminal 1 based on the priority of each attribute of the language stored for the mobile terminal 1. The server 2 returns the conversion candidates to the mobile terminal 1 in an adjusted order.
　携帯端末１は、サーバ２において調整された並びで変換候補を表示し、ユーザが選択した変換候補を、今回入力された読み文字列に対する、確定文字列にする。また、携帯端末１は、自端末を識別する識別コードとともに、確定文字列をサーバ２に送信する。 The mobile terminal 1 displays conversion candidates in an adjusted arrangement on the server 2, and makes the conversion candidates selected by the user a definite character string for the reading character string input this time. Further, the mobile terminal 1 transmits a definite character string to the server 2 together with an identification code for identifying the own terminal.
　サーバ２は、携帯端末１毎に、その携帯端末１から送信されてきた確定文字列を、言語の属性別に集計する。サーバ２は、確定文字列について判断する言語の属性は、１つである場合もあれば、複数である場合もある。サーバ２は、判断した確定文字列の言語の属性が複数である場合、判断した属性毎に集計する。これにより、サーバ２は、携帯端末１毎に、その携帯端末１でユーザが普段の文字入力で使用している言語の属性を集計することができる。 The server 2 aggregates the definite character strings transmitted from the mobile terminal 1 for each mobile terminal 1 according to the language attribute. The server 2 may have one language attribute or a plurality of language attributes for determining the fixed character string. When the server 2 has a plurality of language attributes of the determined definite character string, the server 2 aggregates each of the determined attributes. As a result, the server 2 can aggregate the attributes of the language that the user normally uses for character input on the mobile terminal 1 for each mobile terminal 1.
　サーバ２は、携帯端末１毎に、その携帯端末１にかかる確定文字列の言語の属性推定結果に基づき、属性別に優先度を推定する。サーバ２は、上記したように、携帯端末１から送信されてきた変換候補の並びを、当該携帯端末１について記憶している言語の属性別の優先度に基づいて調整する。すなわち、サーバ２は、携帯端末１から送信されてきた変換候補の並びを、その携帯端末１において普段使用されている言語の属性に基づいて調整する。 The server 2 estimates the priority for each mobile terminal 1 based on the attribute estimation result of the language of the definite character string applied to the mobile terminal 1. As described above, the server 2 adjusts the sequence of conversion candidates transmitted from the mobile terminal 1 based on the priority of each attribute of the language stored for the mobile terminal 1. That is, the server 2 adjusts the sequence of conversion candidates transmitted from the mobile terminal 1 based on the attributes of the language normally used in the mobile terminal 1.
　したがって、携帯端末１においては、ユーザが入力した読み文字列に対して、ユーザが普段使用している属性の変換候補を上位に表示させることができる。特に、ユーザがこれまであまり入力していない読み文字列（初めて入力する読み文字列を含む。）であっても、ユーザが普段使用している属性の変換候補を上位に表示させることができる。したがって、文字入力におけるユーザの操作性の向上が図れる。 Therefore, in the mobile terminal 1, the conversion candidates of the attributes normally used by the user can be displayed at the higher level for the reading character string input by the user. In particular, even if the reading character string is not input by the user so far (including the reading character string input for the first time), the conversion candidates of the attributes normally used by the user can be displayed at the higher level. Therefore, it is possible to improve the user's operability in character input.
　＜２．構成例＞
　図３は、この例の携帯端末の主要部の構成を示すブロック図である。携帯端末１は、制御ユニット１１と、画面表示部１２と、操作位置検出部１３と、通信部１４と、辞書データベース１５（辞書ＤＢ１５）と、表示器５１と、タッチパネル５２とを備えている。 <2. Configuration example>
FIG. 3 is a block diagram showing a configuration of a main part of the mobile terminal of this example. The mobile terminal 1 includes a control unit 11, a screen display unit 12, an operation position detection unit 13, a communication unit 14, a dictionary database 15 (dictionary DB 15), a display 51, and a touch panel 52.

Further, the control unit 11 performs character input processing and the like, which will be described later. Further, in this example, the control unit 11 has a conversion candidate extraction unit 11a. The conversion candidate extraction unit 11a extracts conversion candidates for the reading character string input by the user. Conversion candidates include not only conversion candidates whose reading exactly matches the reading string entered by the user, but also predictive conversions in which the reading prefixes the reading string entered by the user.
　画面表示部１２は、制御ユニット１１から入力された指示にしたがって、表示器５１における画面表示を制御する。 The screen display unit 12 controls the screen display on the display 51 according to the instruction input from the control unit 11.
　操作位置検出部１３は、表示器５１の画面上に貼付されているタッチパネル５２上におけるユーザの操作位置（押下位置）を検出し、制御ユニット１１に出力する。タッチパネル５２、および操作位置検出部１３が、この発明で言う、文字入力装置の操作部に相当する。 The operation position detection unit 13 detects the user's operation position (pressing position) on the touch panel 52 attached to the screen of the display 51, and outputs it to the control unit 11. The touch panel 52 and the operation position detection unit 13 correspond to the operation unit of the character input device referred to in the present invention.
　通信部１４は、ネットワーク２００を介して接続されたサーバ２と通信を行う。また、通信部１４は、サーバ２以外の機器との通信も行う。通信部１４は、例えば、ネットワークを介して接続されたＷｅｂサーバ（上記したサーバ２以外の機器）からＷｅｂページを取得するデータ通信を行う。また、通信部１４は、他の携帯端末等との音声通信、電子メールの送受信、ＳＮＳ（Social　Networking　Service）等にかかる通信も行う。通信部１４が、この発明で言う、文字入力装置の第２通信部に相当する。 The communication unit 14 communicates with the server 2 connected via the network 200. The communication unit 14 also communicates with a device other than the server 2. The communication unit 14 performs data communication for acquiring a Web page from a Web server (device other than the above-mentioned server 2) connected via a network, for example. In addition, the communication unit 14 also performs voice communication with other mobile terminals and the like, transmission and reception of e-mails, and communication related to SNS (Social Networking Service) and the like. The communication unit 14 corresponds to the second communication unit of the character input device as referred to in the present invention.
　辞書ＤＢ１５は、単語別に、その単語の文字列、読み文字列、品詞等を対応付けて登録したデータベースである。辞書ＤＢ１５は、入力された読み文字列に対応する変換候補を抽出するのに用いられる。 The dictionary DB 15 is a database in which a character string, a reading character string, a part of speech, etc. of the word are registered in association with each word. The dictionary DB 15 is used to extract conversion candidates corresponding to the input reading character string.
　携帯端末１は、様々な種類のアプリケーションプログラム（以下、単にアプリと言う。）を実行できる。例えば、Ｗｅｂサーバにアクセスして取得した任意のＷｅｂページを表示器５１の画面に表示するアプリ、スケジュールを管理するアプリ、ＳＮＳにかかるアプリを実行できる。携帯端末１は、アプリで文字入力が行われるときに、辞書ＤＢ１５を利用する。 The mobile terminal 1 can execute various types of application programs (hereinafter, simply referred to as applications). For example, an application that displays an arbitrary Web page acquired by accessing a Web server on the screen of the display unit 51, an application that manages a schedule, and an application related to SNS can be executed. The mobile terminal 1 uses the dictionary DB 15 when character input is performed by the application.
　なお、辞書ＤＢ１５は、システム辞書と、ユーザ辞書との２つに分かれていてもよい。 The dictionary DB 15 may be divided into a system dictionary and a user dictionary.
　携帯端末１の制御ユニット１１は、ハードウェアＣＰＵ、メモリ、その他の電子回路によって構成されている。ハードウェアＣＰＵが、文字の入力にかかる処理プログラム（文字入力プログラム）を実行したときに、後述する文字入力処理を実行する。また、メモリは、この文字入力処理プログラムを展開する領域や、この文字入力処理プログラムの実行時に生じたデータ等を一時記憶する領域を有している。制御ユニット１１は、ハードウェアＣＰＵ、メモリ等を一体化したＬＳＩであってもよい。 The control unit 11 of the mobile terminal 1 is composed of a hardware CPU, a memory, and other electronic circuits. When the hardware CPU executes a processing program (character input program) for inputting characters, the character input processing described later is executed. Further, the memory has an area for expanding the character input processing program and an area for temporarily storing data and the like generated when the character input processing program is executed. The control unit 11 may be an LSI in which a hardware CPU, a memory, and the like are integrated.
　図４は、サーバの主要部の構成を示すブロック図である。サーバ２は、制御ユニット２１と、通信部２２と、辞書データベース２３（辞書ＤＢ２３）とを備えている。 FIG. 4 is a block diagram showing the configuration of the main part of the server. The server 2 includes a control unit 21, a communication unit 22, and a dictionary database 23 (dictionary DB 23).
　制御ユニット２１は、サーバ２本体各部の動作を制御する。また、制御ユニット２１は、変換候補取得部３１、確定文字列取得部３２、集計部３３、推定部３４、および調整部３５を有している。制御ユニット２１が有する変換候補取得部３１、確定文字列取得部３２、集計部３３、推定部３４、および調整部３５の詳細については後述する。 The control unit 21 controls the operation of each part of the server 2 main body. Further, the control unit 21 has a conversion candidate acquisition unit 31, a fixed character string acquisition unit 32, an aggregation unit 33, an estimation unit 34, and an adjustment unit 35. The details of the conversion candidate acquisition unit 31, the fixed character string acquisition unit 32, the aggregation unit 33, the estimation unit 34, and the adjustment unit 35 of the control unit 21 will be described later.
　通信部２２は、ネットワーク介して接続された携帯端末１との通信を行う。通信部２２が、この発明で言う、サーバの第１通信部に相当する。 The communication unit 22 communicates with the mobile terminal 1 connected via the network. The communication unit 22 corresponds to the first communication unit of the server as referred to in the present invention.
　辞書ＤＢ２３は、単語別に、その単語の文字列、読み文字列、品詞、および言語の属性等を対応付けて登録したデータベースである。辞書ＤＢ２３は、各単語に言語の属性を対応づけている点で、携帯端末１の辞書ＤＢ１５と相違する。 The dictionary DB 23 is a database in which a character string, a reading character string, a part of speech, a language attribute, etc. of the word are registered in association with each word. The dictionary DB 23 is different from the dictionary DB 15 of the mobile terminal 1 in that each word is associated with a language attribute.
　なお、携帯端末１の辞書ＤＢ１５も、各単語に言語の属性を対応づけた構成であってもよい。 The dictionary DB 15 of the mobile terminal 1 may also have a configuration in which each word is associated with a language attribute.
　次に、制御ユニット２１が有する、変換候補取得部３１、確定文字列取得部３２、集計部３３、推定部３４、および調整部３５について説明する。 Next, the conversion candidate acquisition unit 31, the fixed character string acquisition unit 32, the aggregation unit 33, the estimation unit 34, and the adjustment unit 35 of the control unit 21 will be described.
　この例では、携帯端末１は、ユーザの操作によって入力された読み文字列に対する変換候補を、辞書ＤＢ１５を参照して抽出する。携帯端末１は、抽出した変換候補をサーバ２に送信する。このとき、携帯端末１は、自端末を識別する識別コードとともに、抽出した変換候補をサーバ２に送信する。携帯端末１は、例えば変換候補を抽出した順番に並べてサーバ２に送信する。サーバ２は、携帯端末１から送信されてきた変換候補を受信する。携帯端末１とサーバ２との通信は、通信部１４、２２において行われる。 In this example, the mobile terminal 1 extracts conversion candidates for the reading character string input by the user's operation by referring to the dictionary DB 15. The mobile terminal 1 transmits the extracted conversion candidates to the server 2. At this time, the mobile terminal 1 transmits the extracted conversion candidates to the server 2 together with the identification code for identifying the own terminal. For example, the mobile terminal 1 arranges conversion candidates in the order in which they are extracted and transmits them to the server 2. The server 2 receives the conversion candidate transmitted from the mobile terminal 1. Communication between the mobile terminal 1 and the server 2 is performed by the communication units 14 and 22.
　変換候補取得部３１は、通信部２２において受信した変換候補（携帯端末１から送信されてきた変換候補）を取得する。例えば、携帯端末１は、ユーザによって入力された読み文字列が「ほんまにたいへんです」であった場合、「本間に大変です」、「ほんまに大変です」、「ホンマに大変です」等の変換候補を抽出し、サーバ２に送信する。 The conversion candidate acquisition unit 31 acquires the conversion candidate (conversion candidate transmitted from the mobile terminal 1) received by the communication unit 22. For example, in the mobile terminal 1, when the reading character string input by the user is "It's really hard", it is converted to "It's hard for Honma", "It's really hard", "It's hard for Honma", etc. Candidates are extracted and sent to the server 2.
　また、携帯端末１は、ユーザが入力した読み文字列に対して確定文字列を選択する操作を行うと、選択された確定文字列をサーバ２に送信する。このとき、携帯端末１は、自端末を識別する識別コードとともに、確定文字列をサーバ２に送信する。 Further, when the mobile terminal 1 performs an operation of selecting a confirmed character string for the reading character string input by the user, the selected confirmed character string is transmitted to the server 2. At this time, the mobile terminal 1 transmits a definite character string to the server 2 together with an identification code for identifying the own terminal.
　確定文字列取得部３２は、通信部２２において受信した確定文字列（携帯端末１から送信されてきた確定文字列）を取得する。例えば、携帯端末１は、ユーザによって入力された読み文字列が「ほんまにたいへんです」であった場合に、「ほんまに大変です」が確定文字列として選択されると、この「ほんまに大変です」を確定文字列としてサーバ２に送信する。 The definite character string acquisition unit 32 acquires the definite character string (confirmed character string transmitted from the mobile terminal 1) received by the communication unit 22. For example, in the mobile terminal 1, when the reading character string input by the user is "really difficult" and "really difficult" is selected as the definite character string, this "really difficult" is selected. Is transmitted to the server 2 as a definite character string.
　集計部３３は、確定文字列取得部３２で確定文字列を取得すると、この確定文字列を送信してきた携帯端末１について言語の属性を集計する。集計部３３は、携帯端末１毎に、図５に示す属性集計テーブル３３ａを作成する。この属性集計テーブル３３ａは、メモリ、ＨＤＤ（Hard　Disk　Drive）、ＳＳＤ（Solid　State　Drive）等の記憶媒体に記憶されている。各属性集計テーブル３３ａには、対応する携帯端末１の識別コードが登録されている。図４は、識別コードが0123456789である携帯端末１の属性集計テーブル３３ａを示している。 When the confirmation character string acquisition unit 32 acquires the confirmation character string, the aggregation unit 33 aggregates the language attributes of the mobile terminal 1 that has transmitted the confirmation character string. The totaling unit 33 creates the attribute totaling table 33a shown in FIG. 5 for each mobile terminal 1. This attribute aggregation table 33a is stored in a storage medium such as a memory, an HDD (Hard Disk Drive), and an SSD (Solid State Drive). The identification code of the corresponding mobile terminal 1 is registered in each attribute aggregation table 33a. FIG. 4 shows the attribute aggregation table 33a of the mobile terminal 1 whose identification code is 0123456789.
　また、属性集計テーブル３３ａは、言語の属性別に確定文字列として選択された選択回数（ユーザが文字入力において使用した使用回数）を対応付けたテーブルである。言語の属性は、上記した通り、方言の種類、技術分野の種類、ネット用語等である。方言の種類は、例えば、関西弁、津軽弁、広島弁に細分類される。また、技術分野の種類は、例えば、ＩＴ技術、医療技術、土木技術、ＡＩ技術に細分類される。この例では、ネット用語については、細分類が設定されていない。 Further, the attribute summary table 33a is a table associated with the number of selections (the number of times the user has used in character input) selected as a definite character string for each language attribute. As described above, the attributes of the language are the type of dialect, the type of technical field, the net terminology, and the like. The types of dialects are subdivided into, for example, Kansai dialect, Tsugaru dialect, and Hiroshima dialect. Further, the types of technical fields are subdivided into, for example, IT technology, medical technology, civil engineering technology, and AI technology. In this example, no subdivision is set for net terms.
　集計部３３は、今回取得した確定文字列の属性（属性の細分類）を判断する。例えば、方言については、関西弁、津軽弁、広島弁等を判断するが、細分類が無いネット用語については、ネット用語と判断する。また、集計部３３は、今回確定文字列を取得した携帯端末１の属性集計テーブル３３ａに対して、今回取得した確定文字列の属性の使用回数を１カウントアップする。このとき、集計部３３は、今回取得した確定文字列について判断した属性が複数である場合、それぞれの属性の使用回数を１カウントアップする。 The aggregation unit 33 determines the attribute (subdivision of the attribute) of the confirmed character string acquired this time. For example, for dialects, Kansai dialect, Tsugaru dialect, Hiroshima dialect, etc. are judged, but net terms without subclassification are judged as net terms. Further, the aggregation unit 33 counts up the number of times the attribute of the confirmed character string acquired this time is used with respect to the attribute aggregation table 33a of the mobile terminal 1 that has acquired the confirmed character string this time. At this time, if there are a plurality of attributes determined for the confirmed character string acquired this time, the aggregation unit 33 counts up the number of times each attribute is used by one.
　推定部３４は、今回変換候補を取得した携帯端末１の属性集計テーブル３３ａを参照し、言語の属性別に優先度を推定する。ここで優先度の推定は、属性に細分類があれば、細分類別に行う。例えば、方言については、関西弁、津軽弁、広島弁毎に優先度を推定するが、細分類が無いネット用語については、ネット用語の優先度を推定する。また、言語の属性の優先度は、使用回数が多い属性ほど高くなる。例えば、優先度は、使用回数に予め定めた係数を乗じた値である。この係数は、正の値であればよい。 The estimation unit 34 refers to the attribute aggregation table 33a of the mobile terminal 1 that has acquired the conversion candidate this time, and estimates the priority for each language attribute. Here, if the attributes have sub-classifications, the priority is estimated for each sub-classification. For example, for dialects, the priority is estimated for each Kansai dialect, Tsugaru dialect, and Hiroshima dialect, but for net terms that do not have subdivisions, the priority of net terms is estimated. In addition, the priority of language attributes is higher as the number of times of use increases. For example, the priority is a value obtained by multiplying the number of times of use by a predetermined coefficient. This coefficient may be a positive value.
　調整部３５は、変換候補取得部３１が今回取得した変換候補の並びを、推定部３４が属性別に推定した優先度に基づいて調整する。例えば、調整部３５は、変換候補毎に、その変換候補の属性の優先度（第１の優先度）と、この変換候補自体の優先度（第２の優先度）との加算値を、当該変換候補の調整値として算出する。第１の優先度は、推定部３４によって推定された優先度である。第２の優先度は、例えば、公知の文字入力装置で行われている文字入力の履歴等に基づいて算出された値にすればよい。調整部３５は、今回取得した変換候補毎に調整値を算出し、今回取得した変換候補を調整値が大きい順に並べ替える。 The adjustment unit 35 adjusts the arrangement of conversion candidates acquired this time by the conversion candidate acquisition unit 31 based on the priority estimated by the estimation unit 34 for each attribute. For example, the adjusting unit 35 sets the added value of the priority of the attribute of the conversion candidate (first priority) and the priority of the conversion candidate itself (second priority) for each conversion candidate. Calculated as an adjustment value for conversion candidates. The first priority is the priority estimated by the estimation unit 34. The second priority may be, for example, a value calculated based on the history of character input performed by a known character input device. The adjustment unit 35 calculates an adjustment value for each conversion candidate acquired this time, and sorts the conversion candidates acquired this time in descending order of the adjustment value.
　なお、調整値は、推定部３４によって推定された優先度にしてもよい。 The adjustment value may be the priority estimated by the estimation unit 34.
　サーバ２は、今回取得した変換候補を調整部３５において並び替えられた順番で携帯端末１に表示させる返信を行う。 The server 2 makes a reply to display the conversion candidates acquired this time on the mobile terminal 1 in the order sorted by the adjustment unit 35.
　サーバ２の制御ユニット２１は、ハードウェアＣＰＵ、メモリ、その他の電子回路によって構成されている。この制御ユニット２１が、この発明で言う変換候補調整ユニットに相当する。ハードウェアＣＰＵが、この発明にかかる変換候補調整プログラムを実行したときに、変換候補取得部３１、確定文字列取得部３２、集計部３３、推定部３４、および調整部３５として動作する。また、メモリは、この発明にかかる変換候補調整プログラムを展開する領域や、この変換候補調整プログラムの実行時に生じたデータ等を一時記憶する領域を有している。制御ユニット２１は、ハードウェアＣＰＵ、メモリ等を一体化したＬＳＩであってもよい。また、ハードウェアＣＰＵが、この発明にかかる変換候補調整方法を実行するコンピュータである。 The control unit 21 of the server 2 is composed of a hardware CPU, a memory, and other electronic circuits. The control unit 21 corresponds to the conversion candidate adjustment unit referred to in the present invention. When the hardware CPU executes the conversion candidate adjustment program according to the present invention, it operates as a conversion candidate acquisition unit 31, a fixed character string acquisition unit 32, an aggregation unit 33, an estimation unit 34, and an adjustment unit 35. Further, the memory has an area for expanding the conversion candidate adjustment program according to the present invention and an area for temporarily storing data and the like generated when the conversion candidate adjustment program is executed. The control unit 21 may be an LSI in which a hardware CPU, a memory, and the like are integrated. Further, the hardware CPU is a computer that executes the conversion candidate adjustment method according to the present invention.
　＜３．動作例＞
　図６は、携帯端末における文字入力処理を示すフローチャートである。図７は、サーバにおける変換候補調整処理を示すフローチャートである。 <3. Operation example>
FIG. 6 is a flowchart showing a character input process in a mobile terminal. FIG. 7 is a flowchart showing a conversion candidate adjustment process in the server.
　携帯端末１は、ソフトウェアキーボードにかかる画面を表示器５１に表示させている。 The mobile terminal 1 displays the screen on the software keyboard on the display 51.
　携帯端末１の制御ユニット１１は、操作位置検出部１３において検出されたタッチパネル５２上のユーザの操作位置に基づいて、ユーザの入力操作を判断する。ユーザの操作が、文字入力にかかる操作であれば、この操作で入力された文字を読み文字列表示領域６１に追加する（ｓ１、ｓ２）。例えば、ユーザは、「ほんまにたいへんです」と入力する場合。文字キーを操作して、「ほ」→「ん」→「ま」→「に」→「た」→「い」→「へ」→「ん」→「で」→「す」と１文字ずつ入力する。 The control unit 11 of the mobile terminal 1 determines a user's input operation based on the user's operation position on the touch panel 52 detected by the operation position detection unit 13. If the user's operation is an operation related to character input, the character input by this operation is added to the reading character string display area 61 (s1, s2). For example, if the user types "It's really hard". Operate the character keys, "ho" → "n" → "ma" → "ni" → "ta" → "i" → "he" → "n" → "de" → "su" one character at a time input.
　携帯端末１は、ユーザが１文字入力する毎に、読み文字列表示領域６１に表示されている文字列（読み文字列）に、今回入力された文字を追加する。例えば、ユーザが、すでに「ほんま」を入力している状態（携帯端末１が「ほんま」を読み文字列表示領域６１に表示している状態）において、「に」を入力する操作を行うと、携帯端末１は、読み文字列表示領域６１に表示されている文字列を「ほんまに」に更新する。 The mobile terminal 1 adds the character input this time to the character string (reading character string) displayed in the reading character string display area 61 each time the user inputs one character. For example, when the user already inputs "honma" (the mobile terminal 1 reads "honma" and displays it in the character string display area 61), an operation of inputting "ni" is performed. The mobile terminal 1 updates the character string displayed in the reading character string display area 61 to "really".
　携帯端末１の変換候補抽出部１１ａが、読み文字列表示領域６１に表示されている読み文字列に対する変換候補を抽出する（ｓ３）。ｓ３で抽出される変換候補には、公知の予測変換候補も含まれる。携帯端末１は、ｓ３で抽出した変換候補をサーバ２に送信し（ｓ４）、サーバ２からの返信を待つ（ｓ５）。携帯端末１とサーバ２との通信は、通信部１４、２２において行われる。 The conversion candidate extraction unit 11a of the mobile terminal 1 extracts conversion candidates for the reading character string displayed in the reading character string display area 61 (s3). The conversion candidates extracted in s3 include known predictive conversion candidates. The mobile terminal 1 transmits the conversion candidate extracted in s3 to the server 2 (s4), and waits for a reply from the server 2 (s5). Communication between the mobile terminal 1 and the server 2 is performed by the communication units 14 and 22.
　サーバ２は、変換候補取得部３１が携帯端末１から送信されてきた変換候補（通信部２２で受信した変換候補）を取得すると（ｓ１１）、この変換候補を送信してきた携帯端末１について、言語の属性別に優先度を推定する（ｓ１３）。携帯端末１は、変換候補とともに、自端末の識別コードを送信している。サーバ２は、該当する携帯端末１の属性集計テーブル３３ａを参照し、言語の属性別の優先度を推定する。推定部３４がｓ１３にかかる処理を行う。ｓ１１が、この発明で言う変換候補取得ステップに相当する処理である。また、ｓ１３が、この発明で言う推定ステップに相当する処理である。 When the conversion candidate acquisition unit 31 acquires the conversion candidate (conversion candidate received by the communication unit 22) transmitted from the mobile terminal 1 (s11), the server 2 describes the language of the mobile terminal 1 that has transmitted the conversion candidate. The priority is estimated for each attribute of (s13). The mobile terminal 1 transmits the identification code of the own terminal together with the conversion candidate. The server 2 refers to the attribute aggregation table 33a of the corresponding mobile terminal 1 and estimates the priority for each language attribute. The estimation unit 34 performs the processing related to s13. s11 is a process corresponding to the conversion candidate acquisition step referred to in the present invention. Further, s13 is a process corresponding to the estimation step referred to in the present invention.
　調整部３５が、ｓ１３で推定した言語の属性別の優先度を用いて、ｓ１１で取得した変換候補の並びを調整する（ｓ１４）。ｓ１４では、調整部３５は、例えば、変換候補毎に、その変換候補の属性の優先度（第１の優先度）と、この変換候補自体の優先度（第２の優先度）との加算値を、当該変換候補の調整値として算出する。第１の優先度は、推定部３４によって推定された優先度である。第２の優先度は、例えば、公知の文字入力装置で行われている文字入力の履歴等に基づいて算出された値である。調整部３５は、今回取得した変換候補毎に調整値を算出し、今回取得した変換候補を調整値が大きい順に並べ替える。ｓ１４が、この発明で言う調整ステップに相当する処理である。 The adjustment unit 35 adjusts the arrangement of conversion candidates acquired in s11 using the priority of each language attribute estimated in s13 (s14). In s14, the adjusting unit 35, for example, for each conversion candidate, is an addition value of the priority of the attribute of the conversion candidate (first priority) and the priority of the conversion candidate itself (second priority). Is calculated as the adjustment value of the conversion candidate. The first priority is the priority estimated by the estimation unit 34. The second priority is a value calculated based on, for example, a history of character input performed by a known character input device. The adjustment unit 35 calculates an adjustment value for each conversion candidate acquired this time, and sorts the conversion candidates acquired this time in descending order of the adjustment value. s14 is a process corresponding to the adjustment step referred to in the present invention.
　サーバ２は、ｓ１４で調整した変換候補の並びを、携帯端末１に返信し（ｓ１５）、ｓ１１に戻る。 The server 2 returns the sequence of conversion candidates adjusted in s14 to the mobile terminal 1 (s15), and returns to s11.
　携帯端末１は、ｓ５でサーバからの返信を受信すると、変換候補をサーバ２において調整された順番に並べて、変換候補表示領域６２に表示する（ｓ６）。携帯端末１は、ユーザによる確定文字列の選択操作、または新たな文字の入力操作を待つ（ｓ７、ｓ８）。携帯端末１は、ユーザが新たな文字の入力操作を行うと、ｓ２に戻る。また、携帯端末１は、ユーザが確定文字列の選択操作を行うと、今回選択された変換候補を、今回入力された読み文字列の確定文字列に確定する確定処理を行う（ｓ９）。また、ｓ９では、今回確定された確定文字列をサーバ２に送信する。 When the mobile terminal 1 receives the reply from the server in s5, the conversion candidates are arranged in the adjusted order in the server 2 and displayed in the conversion candidate display area 62 (s6). The mobile terminal 1 waits for a confirmation character string selection operation or a new character input operation by the user (s7, s8). The mobile terminal 1 returns to s2 when the user performs a new character input operation. Further, when the user performs the confirmation operation of the confirmation character string, the mobile terminal 1 performs the confirmation processing of confirming the conversion candidate selected this time to the confirmation character string of the reading character string input this time (s9). Further, in s9, the confirmed character string confirmed this time is transmitted to the server 2.
　サーバ２は、確定文字列取得部３２が携帯端末１から送信されてきた確定文字列（通信部２２で受信した確定文字列）を取得すると（ｓ１２）、この確定文字列を送信してきた携帯端末１について記憶している、属性集計テーブル３３ａを更新し（ｓ１６）、ｓ１１に戻る。ｓ１２が、この発明で言う確定文字列取得ステップに相当する処理である。また、集計部３３が、ｓ１６にかかる処理を行う。集計部３３は、例えば、今回取得した確定文字列を単語単位に分割する。集計部３３は、分割した単語毎に、言語の属性を判断する。集計部３３は、分割した単語毎に、判断した言語の属性に対する使用回数（属性集計テーブル３３ａに登録されている使用回数）を１カウントアップさせる。 When the definite character string acquisition unit 32 acquires the definite character string (confirmed character string received by the communication unit 22) transmitted from the mobile terminal 1 (s12), the server 2 transmits the definite character string to the mobile terminal. The attribute summary table 33a stored for 1 is updated (s16), and the process returns to s11. s12 is a process corresponding to the definite character string acquisition step referred to in the present invention. Further, the totaling unit 33 performs the processing related to s16. The aggregation unit 33, for example, divides the confirmed character string acquired this time into word units. The aggregation unit 33 determines the language attribute for each divided word. The totaling unit 33 counts up the number of times of use (the number of times of use registered in the attribute totaling table 33a) for the attribute of the determined language for each divided word by one.
　このように、この例では、ユーザが文字入力で確定した文字列（確定文字列）の言語の属性によって、変換候補を表示する順序の調整が行われる。すなわち、ユーザが普段使用している言語の属性に応じて変換候補が並べられる。例えば、ユーザが、文字入力で関西弁を普段使用していると、以前あまり入力していない「ええんやで」を読み文字列として入力した場合であっても、変換候補を「ええんやで」（関西弁）、「エエンヤデ」、「ええんや出」、「ええん屋で」等の順番に調整して表示できる。また、ユーザが普段使用している言語の属性がＩＴ技術であれば、ＩＴ技術にかかる文字列の変換候補を上位に表示させることができる。 As described above, in this example, the order of displaying conversion candidates is adjusted according to the language attribute of the character string (confirmed character string) confirmed by the user by inputting the character. That is, conversion candidates are arranged according to the attributes of the language that the user usually uses. For example, if the user normally uses the Kansai dialect for character input, even if "Enya de", which was not input much before, is input as a reading character string, the conversion candidate is "Eenya". It can be adjusted and displayed in the order of "de" (Kansai dialect), "Eenyade", "Enyade", "Eenya de", etc. Further, if the attribute of the language that the user usually uses is IT technology, the conversion candidate of the character string related to IT technology can be displayed at the higher level.
　したがって、この例では、ユーザが入力した読み文字列に対して、ユーザが普段使用している属性の変換候補を上位に表示させることができる。特に、ユーザがこれまであまり入力していない読み文字列（初めて入力する読み文字列を含む。）であっても、ユーザが普段使用している属性の変換候補を上位に表示させることができ、文字入力におけるユーザの操作性の向上が図れる。 Therefore, in this example, the conversion candidates of the attributes normally used by the user can be displayed at the higher level for the reading character string input by the user. In particular, even if the reading character string that the user has not input so far (including the reading character string that is input for the first time), the conversion candidates of the attributes that the user usually uses can be displayed at the top. The user's operability in character input can be improved.
　＜４．変形例＞
　・変形例１
　この変形例１にかかる文字変換システム１００Ａは、図８に示すように、インタネット等のネットワーク２００を介してデータ通信可能に接続された携帯端末１Ａと、サーバ２Ａとを備えている。すなわち、この変形例１にかかる文字変換システム１００Ａも、上記した例と同様の構成である。 <4. Modification example>
-Modification example 1
As shown in FIG. 8, the character conversion system 100A according to the first modification includes a mobile terminal 1A and a server 2A connected so as to be capable of data communication via a network 200 such as an Internet. That is, the character conversion system 100A according to the modified example 1 has the same configuration as the above-mentioned example.
　図９は、この変形例１の携帯端末の主要部の構成を示すブロック図である。図９では、上記した例の携帯端末１の構成（図３に示した構成）と同様の構成については、同じ符号を付している。 FIG. 9 is a block diagram showing the configuration of the main part of the mobile terminal of the modified example 1. In FIG. 9, the same reference numerals are given to the same configurations as those of the mobile terminal 1 in the above example (the configuration shown in FIG. 3).
　図９に示すように、この変形例１の携帯端末１Ａは、上記した例で説明した変換候補抽出部１１ａを備えていない。また、この変形例１の携帯端末１Ａは、上記した例で説明した辞書ＤＢ１５を備えていない。すなわち、携帯端末１Ａは、変換候補抽出部１１ａ、および辞書ＤＢ１５を備えていない点で、上記した例の携帯端末１と相違する。 As shown in FIG. 9, the mobile terminal 1A of this modification 1 does not include the conversion candidate extraction unit 11a described in the above example. Further, the mobile terminal 1A of this modification 1 does not have the dictionary DB 15 described in the above example. That is, the mobile terminal 1A is different from the mobile terminal 1 in the above example in that it does not include the conversion candidate extraction unit 11a and the dictionary DB 15.
　図１０は、この変形例１のサーバの主要部の構成を示すブロック図である。図１０では、上記した例のサーバ２の構成（図３に示した構成）と同様の構成については、同じ符号を付している。 FIG. 10 is a block diagram showing the configuration of the main part of the server of this modification 1. In FIG. 10, the same reference numerals are given to the configurations similar to the configuration of the server 2 in the above example (the configuration shown in FIG. 3).
　図１０に示すように、この変形例のサーバ２Ａは、上記した例の変換候補取得部３１を変換候補取得部３１Ａに置き換えた構成である。この変換候補取得部３１Ａは、上記した例の変換候補抽出部１１ａと同様の構成であり、ユーザによって入力された読み文字列に対する変換候補を抽出することによって、変換候補を取得する。変換候補取得部３１Ａは、辞書ＤＢ２３を参照して、ユーザによって入力された読み文字列に対する変換候補を抽出する。 As shown in FIG. 10, the server 2A of this modified example has a configuration in which the conversion candidate acquisition unit 31 of the above example is replaced with the conversion candidate acquisition unit 31A. The conversion candidate acquisition unit 31A has the same configuration as the conversion candidate extraction unit 11a in the above example, and acquires conversion candidates by extracting conversion candidates for the reading character string input by the user. The conversion candidate acquisition unit 31A refers to the dictionary DB 23 and extracts conversion candidates for the reading character string input by the user.
　図１１は、変形例１の携帯端末における文字入力処理を示すフローチャートである。図１２は、変形例１のサーバにおける変換候補調整処理を示すフローチャートである。図１１では、図６に示した処理と同じ処理については、同じステップ番号を付している。図１２では、図７に示した処理と同じ処理については、同じステップ番号を付している。 FIG. 11 is a flowchart showing a character input process in the mobile terminal of the first modification. FIG. 12 is a flowchart showing a conversion candidate adjustment process in the server of the modification example 1. In FIG. 11, the same step numbers are assigned to the same processes as those shown in FIG. In FIG. 12, the same step numbers are assigned to the same processes as those shown in FIG. 7.
　図１１に示すように、この変形例１の携帯端末１Ａは、上記した例の携帯端末１と同様に、ユーザの操作が、文字入力にかかる操作であれば、この操作で入力された文字を読み文字列表示領域６１に追加する（ｓ１、ｓ２）。この変形例１の携帯端末１Ａは、上記した例のｓ３にかかる処理（読み文字列に対する変換候補を抽出する処理）、およびｓ４にかかる処理（抽出した変換候補をサーバ２に送信する処理）に替えて、この時点における読み文字列をサーバ２Ａに送信し（ｓ２１）、上記した例で説明したｓ５以降の処理を実行する。 As shown in FIG. 11, the mobile terminal 1A of the modification 1 has the same as the mobile terminal 1 of the above-mentioned example, if the user's operation is an operation related to character input, the character input by this operation is input. It is added to the reading character string display area 61 (s1, s2). The mobile terminal 1A of the modification 1 is used for the process related to s3 of the above example (process of extracting conversion candidates for the reading character string) and the process related to s4 (process of transmitting the extracted conversion candidates to the server 2). Instead, the reading character string at this point is transmitted to the server 2A (s21), and the processing after s5 described in the above example is executed.
　このように、この変形例１の携帯端末１Ａは、ユーザの操作によって入力された読み文字列に対する変換候補を抽出せず、ユーザの操作によって入力された読み文字列をサーバ２Ａに送信する点で上記の例と相違する。 As described above, the mobile terminal 1A of the modification 1 does not extract conversion candidates for the reading character string input by the user's operation, but transmits the reading character string input by the user's operation to the server 2A. Different from the above example.
　また、この変形例１のサーバ２Ａは、変換候補取得部３１が携帯端末１から送信されてきた読み文字列（通信部２２で受信した読み文字列）を取得すると（ｓ３１）、この読み文字列に対する変換候補を取得する（ｓ３２）。ｓ３２は、上記したｓ３と同様の処理である。すなわち、この変形例１では、ユーザの操作によって入力された読み文字列に対する変換候補の取得を、携帯端末１Ａが行うのではなく、サーバ２Ａが行う点で、上記の例と相違する。 Further, when the conversion candidate acquisition unit 31 acquires the reading character string (reading character string received by the communication unit 22) transmitted from the mobile terminal 1, the server 2A of the modification 1 acquires the reading character string (s31). The conversion candidate for is acquired (s32). s32 is the same process as s3 described above. That is, this modification 1 is different from the above example in that the mobile terminal 1A does not acquire the conversion candidate for the reading character string input by the user's operation, but the server 2A.
　サーバ２Ａは、ｓ３２で変換候補を取得すると、上記した例で説明したｓ１３以降の処理を実行する。 When the server 2A acquires the conversion candidate in s32, the server 2A executes the processing after s13 described in the above example.
　なお、この変形例１のサーバ２Ａは、上記した例と同様に、確定文字列取得部３２が携帯端末１から送信されてきた確定文字列（通信部２２で受信した確定文字列）を取得すると（ｓ１２）、この確定文字列を送信してきた携帯端末１Ａについて記憶している、属性集計テーブル３３ａを更新し（ｓ１６）、ｓ３１に戻る。 In addition, when the server 2A of this modification 1 acquires the definite character string (the definite character string received by the communication unit 22) transmitted from the mobile terminal 1 by the definite character string acquisition unit 32, as in the above example. (S12), the attribute aggregation table 33a stored for the mobile terminal 1A that has transmitted this fixed character string is updated (s16), and the process returns to s31.
　この変形例１の携帯端末１Ａは、上記した通り、ユーザの操作によって入力された読み文字列に対する変換候補の取得にかかる処理を行わないので、文字入力にかかる処理負荷が軽減できるだけでなく、辞書ＤＢ１５を不要にできるので、本体の小型化が図れる。 As described above, the mobile terminal 1A of the modification 1 does not perform the processing related to the acquisition of the conversion candidate for the reading character string input by the user's operation, so that not only the processing load on the character input can be reduced, but also the dictionary Since the DB 15 can be eliminated, the size of the main body can be reduced.
　・変形例２
　上記の例では、サーバ２の制御ユニット２１が、変換候補取得部３１、確定文字列取得部３２、集計部３３、推定部３４、および調整部３５を有しているとしたが、図１３に示すように、変換候補取得部３１、確定文字列取得部３２、集計部３３、推定部３４、および調整部３５を携帯端末１Ｂの制御ユニット１１Ｂに設けてもよい。この場合、携帯端末１Ｂは、自端末にかかる属性集計テーブル３３ａを記憶すればよい（他の携帯端末１にかかる属性集計テーブル３３ａを記憶する必要はない。）。また、この場合、携帯端末１Ｂは、サーバ２に対して変換候補、および確定文字列を送信する必要がないので、上記した例のように、ネットワーク２００を介してサーバ２に接続される構成でなくてもない。また、携帯端末１Ａは、自端末の制御ユニット１１Ｂに設けた変換候補取得部３１、確定文字列取得部３２、集計部３３、推定部３４、および調整部３５によって、上記した例において携帯端末１Ａ、およびサーバ２Ａが実行していた処理（図１１、および図１２に示した処理）を行えばよい。但し、携帯端末１Ａとサーバ２Ａとの間における、ユーザの操作によって入力された読み文字列の送受信、変換候補の並びの送受信、および確定文字列の送受信にかかる処理は行わない。 -Modification example 2
In the above example, it is assumed that the control unit 21 of the server 2 has a conversion candidate acquisition unit 31, a fixed character string acquisition unit 32, an aggregation unit 33, an estimation unit 34, and an adjustment unit 35. As shown, the conversion candidate acquisition unit 31, the fixed character string acquisition unit 32, the aggregation unit 33, the estimation unit 34, and the adjustment unit 35 may be provided in the control unit 11B of the mobile terminal 1B. In this case, the mobile terminal 1B may store the attribute aggregation table 33a related to the own terminal (it is not necessary to store the attribute aggregation table 33a related to the other mobile terminal 1). Further, in this case, since the mobile terminal 1B does not need to transmit the conversion candidate and the definite character string to the server 2, the configuration is such that the mobile terminal 1B is connected to the server 2 via the network 200 as in the above example. Not even without. Further, the mobile terminal 1A is the mobile terminal 1A in the above example by the conversion candidate acquisition unit 31, the fixed character string acquisition unit 32, the aggregation unit 33, the estimation unit 34, and the adjustment unit 35 provided in the control unit 11B of the own terminal. , And the processing executed by the server 2A (the processing shown in FIGS. 11 and 12) may be performed. However, the processing related to the transmission / reception of the reading character string input by the user's operation, the transmission / reception of the sequence of conversion candidates, and the transmission / reception of the confirmed character string between the mobile terminal 1A and the server 2A is not performed.
　・変形例３
　上記の例では、サーバ２の制御ユニット２１は、携帯端末１から変換候補を取得すると、その携帯端末１について言語の属性別の優先度を推定するとしたが、携帯端末１から確定文字列を取得すると、その携帯端末１について言語の属性別の優先度を推定する構成にしてもよい。また、変換候補の調整値についても、携帯端末１から確定文字列を取得したときに算出してもよい。この場合には、推定した言語の属性の優先度、および算出した調整値を属性集計テーブル３３ａに登録しておけばよい。 -Modification example 3
In the above example, when the control unit 21 of the server 2 acquires a conversion candidate from the mobile terminal 1, it estimates the priority of the mobile terminal 1 for each language attribute, but acquires a definite character string from the mobile terminal 1. Then, the mobile terminal 1 may be configured to estimate the priority of each language attribute. Further, the adjustment value of the conversion candidate may also be calculated when the fixed character string is acquired from the mobile terminal 1. In this case, the priority of the estimated language attribute and the calculated adjustment value may be registered in the attribute summary table 33a.
　なお、変形例１のサーバ２Ａは、同様に、携帯端末１Ａから確定文字列を取得すると、その携帯端末１Ａについて言語の属性別の優先度を推定する構成にすればよい。 Similarly, the server 2A of the modification 1 may be configured to estimate the priority of each language attribute for the mobile terminal 1A when the fixed character string is acquired from the mobile terminal 1A.
　このように構成すれば、変換候補を取得したときに、言語の属性の優先度の推定、および調整値の算出にかかる処理を行わなくてよいので、携帯端末１、１Ａにおける変換候補の表示にかかる時間を短縮できる。 With this configuration, when the conversion candidates are acquired, it is not necessary to perform the processing related to the estimation of the priority of the language attribute and the calculation of the adjustment value, so that the conversion candidates are displayed on the mobile terminals 1 and 1A. The time required can be shortened.
　・変形例４
　また、上記の例では、サーバ２、２Ａは、携帯端末１別に属性集計テーブル３３ａを作成する構成であるとしたが、ユーザ別に属性集計テーブル３３ａを作成する構成にしてもよい。すなわち、上記した例における属性集計テーブル３３ａの端末識別コードを、ユーザの識別コードに置き換えてもよい。 -Modification example 4
Further, in the above example, the servers 2 and 2A are configured to create the attribute aggregation table 33a for each mobile terminal 1, but may be configured to create the attribute aggregation table 33a for each user. That is, the terminal identification code of the attribute aggregation table 33a in the above example may be replaced with the user identification code.
　この場合、携帯端末１、１Ａは、ユーザの識別コードを記憶する。ユーザの識別コードは、ユーザ個人を識別することができるコードであればよく、例えばユーザがＳＮＳ等のネットワークサービスの利用において使用しているユーザＩＤであってもよいし、サーバ２、２Ａに対して事前に登録したユーザＩＤであってもよいし、その他のＩＤであってもよい。 In this case, the mobile terminals 1 and 1A store the user's identification code. The user identification code may be any code that can identify the individual user, and may be, for example, a user ID used by the user in using a network service such as SNS, or for servers 2 and 2A. It may be a user ID registered in advance, or it may be another ID.
　また、この変形例４では、携帯端末１は、ｓ４で変換候補をサーバ２に送信するとき、およびｓ９で確定文字列をサーバ２に送信するとき、ユーザの識別コードを一緒に送信する。サーバ２は、携帯端末１から送信されてきたユーザの識別コードによって、該当するユーザの属性集計テーブル３３ａを判断し、その属性集計テーブル３３ａを参照して、言語の属性別の優先度を推定する。 Further, in this modification 4, the mobile terminal 1 transmits the user identification code together when transmitting the conversion candidate to the server 2 in s4 and when transmitting the confirmed character string to the server 2 in s9. The server 2 determines the attribute summary table 33a of the corresponding user based on the user identification code transmitted from the mobile terminal 1, and estimates the priority for each language attribute with reference to the attribute summary table 33a. ..
　また、携帯端末１Ａは、ｓ２１で読み文字列をサーバ２Ａに送信するとき、およびｓ９で確定文字列をサーバ２Ａに送信するとき、ユーザの識別コードを一緒に送信する。サーバ２Ａは、携帯端末１Ａから送信されてきたユーザの識別コードによって、該当するユーザの属性集計テーブル３３ａを判断し、その属性集計テーブル３３ａを参照して、言語の属性別の優先度を推定する。 Further, the mobile terminal 1A also transmits the user identification code when the reading character string is transmitted to the server 2A in s21 and when the confirmed character string is transmitted to the server 2A in s9. The server 2A determines the attribute summary table 33a of the corresponding user based on the user identification code transmitted from the mobile terminal 1A, and estimates the priority for each language attribute with reference to the attribute summary table 33a. ..
　このように構成すれば、例えば、ユーザが複数の携帯端末１、１Ａを所有している場合において、ユーザがいずれの携帯端末１、１Ａで文字入力操作を行っても、そのユーザが普段使用している属性の変換候補を上位に表示させることができる。 With this configuration, for example, when a user owns a plurality of mobile terminals 1, 1A, the user usually uses the character input operation regardless of which mobile terminal 1, 1A the user performs a character input operation. It is possible to display the conversion candidates of the attribute being displayed at the top.
　また、ユーザが所有している携帯端末１、１Ａを別の携帯端末１、１Ａに交換した場合に、交換後の携帯端末１、１Ａで文字入力操作を行ったとき、交換前の携帯端末１、１Ａでの文字入力で普段使用していた属性の変換候補を上位に表示させることができる。 Further, when the mobile terminals 1 and 1A owned by the user are exchanged for other mobile terminals 1 and 1A, and the character input operation is performed on the exchanged mobile terminals 1 and 1A, the mobile terminal 1 before the exchange is performed. It is possible to display the conversion candidates of the attributes normally used in the character input in 1A at the higher level.
　なお、上記の例では、属性集計テーブル３３ａは、言語の属性別に使用回数を登録するとしたが、言語の属性別に使用頻度等の他の情報を登録する構成であってもよい。使用頻度は、例えば、属性別に、その属性の言語の使用回数を入力された文の総数で除した値としてもよいし、その他の手法で算出した値にしてもよい。 In the above example, the attribute aggregation table 33a is supposed to register the number of times of use for each language attribute, but it may be configured to register other information such as the frequency of use for each language attribute. The frequency of use may be, for example, a value obtained by dividing the number of times the language of the attribute is used by the total number of input sentences for each attribute, or a value calculated by another method.
　・変形例５
　文字列として入力される言語の種類は、上記した例の日本語に限らず、他の種類の言語であってもよい。言語の種類は、例えば、文字列として入力したい言葉（所望の文字列）の発音表記をユーザに入力させる方式である中国語であってもよいし、文字列として入力したい言葉のスペルをユーザに入力させる方式である英語、ドイツ語等であってもよい。 -Modification example 5
The type of language input as a character string is not limited to Japanese in the above example, and may be another type of language. The type of language may be, for example, Chinese, which is a method for allowing the user to input the pronunciation notation of the word (desired character string) to be input as a character string, or the spelling of the word to be input as a character string to the user. It may be in English, German, etc., which is a method for inputting.
　例えば、携帯端末１は、文字列として入力される言語の種類が英語である場合、ユーザよって入力された文字列が「art」であるとする。ユーザが普段使用している言語の属性が医療技術であると、携帯端末１の変換候補表示領域６２には、例えば図１４（Ａ）に示すように、「artery」、「arthritis」、「art」・・・の順番に変換候補が表示される。また、ユーザが普段使用している言語の属性が自然科学技術であると、携帯端末１の変換候補表示領域６２には、例えば図１４（Ｂ）に示すように、「artificial」、「art」、「artless」・・・の順番に変換候補が表示される。 For example, in the mobile terminal 1, when the type of language input as a character string is English, the character string input by the user is "art". When the attribute of the language that the user usually uses is medical technology, the conversion candidate display area 62 of the mobile terminal 1 has "artery", "arthritis", and "art" as shown in FIG. 14A, for example. Conversion candidates are displayed in the order of "...". Further, when the attribute of the language that the user usually uses is natural science and technology, the conversion candidate display area 62 of the mobile terminal 1 has "artificial" and "art" as shown in FIG. 14B, for example. , "Artless" ... The conversion candidates are displayed in this order.
　上記した「artery」、「arthritis」、「artificial」、「artless」は、ユーザよって入力された文字列（「art」）に対する予測変換候補である。また、変換候補の並び順は、調整部３５によって調整された順番である。 The above-mentioned "artery", "arthritis", "artificial", and "artless" are predictive conversion candidates for the character string ("art") input by the user. Further, the order of the conversion candidates is the order adjusted by the adjusting unit 35.
　また、上記の説明では、携帯端末１、１Ａ、１Ｂを例にして本願発明を説明したが、本願発明は携帯端末１、１Ａ、１Ｂに限らず、ユーザの操作によって文字入力が行われるデスクトップパソコン等の他の電子機器にも適用できる。 Further, in the above description, the present invention has been described by taking mobile terminals 1, 1A and 1B as an example, but the present invention is not limited to mobile terminals 1, 1A and 1B, and a desktop personal computer in which characters are input by a user's operation. It can also be applied to other electronic devices such as.
　なお、この発明は、上記実施形態そのままに限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で構成要素を変形して具体化できる。また、上記実施形態に開示されている複数の構成要素の適宜な組み合せにより種々の発明を形成できる。例えば、実施形態に示される全構成要素から幾つかの構成要素を削除してもよい。さらに、異なる実施形態に亘る構成要素を適宜組み合せてもよい。 It should be noted that the present invention is not limited to the above embodiment as it is, and at the implementation stage, the components can be modified and embodied within a range that does not deviate from the gist thereof. In addition, various inventions can be formed by an appropriate combination of the plurality of components disclosed in the above-described embodiment. For example, some components may be removed from all the components shown in the embodiments. In addition, components from different embodiments may be combined as appropriate.
