Explanation of symbols

  DESCRIPTION OF SYMBOLS 10 Data input device, 12 Input reception part, 14 Operation switching part, 16 Candidate extraction part, 18 Order determination part, 20 Candidate display part, 22 Calibration support part, 24 Output part, 26 History recording part, 30 Dictionary database, 32 History Database, 40 user interfaces, 50 applications.

  The embodiment proposes a technique for selecting and switching an appropriate operation according to an output destination in a data input device that converts conversion source data input by a user into conversion destination data and outputs the converted data. For example, when converting a reading kana to kanji and inputting it, depending on the input position and sentence structure, the display order of conversion candidates is switched, the dictionary used for conversion is switched, and the data type to be input Information to be displayed and the method of supporting data calibration are switched. Thereby, the convenience of data input can be remarkably improved.

  1 and 2 are diagrams for explaining a method of inputting data to an application using the data input device according to the embodiment. In FIG.1 and FIG.2, the input form 80 for inputting data into the database which stores a patient's treatment history is shown. When the user inputs data to each item of the input form 80, the data input device converts the reading input by the user into kanji and outputs it to the database application.

  FIG. 1 shows a state in which a conversion candidate is displayed by inputting the reading “Masui” in order to input the Chinese character “Masui”, which is the patient's last name. Kanji corresponding to “Masui” includes “Anesthetic”, “Drunk”, “Masui”, “Sakurai”, etc., but here we are trying to input the surname of the patient, so it may be used as a surname It is more convenient to display high-kanji candidates with priority. For this reason, when presenting conversion candidates to the user, the data input device sorts them so that “Masui” and “Sakurai”, which are most likely to be used as surnames, are displayed in higher order.

  FIG. 2 shows a state in which the conversion candidate is displayed by inputting the reading “masui” in order to input the kanji character “anaesthesia” which is a contraindication item of the patient. Here, since a medical practice is to be input, the data input device sorts the “anaesthesia” and “drunkenness” that are most likely to be used as a medical practice, and displays conversion candidates.

  Conventionally, there has been a technique for learning the user's input history and input character strings near the input position, but the contents entered immediately before are reproduced, so when input work is performed in multiple contexts etc. May not provide useful results. For example, in the case of the above-mentioned example, when “Anesthesia” is input as a contraindicated item for a patient and then “Masui” is input as the patient's last name, “Anesthetized”, which is the input character string immediately before, is converted as a conversion candidate "Is displayed at the top. However, as proposed in the present embodiment, the type of data to be input is estimated based on the document structure, context, etc. It becomes possible to estimate accurately.

  FIG. 3 shows a configuration of the data input device 10 according to the embodiment. The data input device 10 supports data input to the application 50 by the user. That is, when the user inputs data to the application 50, the application 50 selects data selected by the user from candidates for conversion destination data recalled from the conversion source data input by the user via the user interface 40. Output for.

  The data input device 10 includes an input reception unit 12, an operation switching unit 14, a candidate extraction unit 16, an order determination unit 18, a candidate display unit 20, a calibration support unit 22, an output unit 24, a history recording unit 26, a dictionary database 30, and A history database 32 is included. In terms of hardware components, these configurations are realized by a CPU of a computer, a memory, a program loaded in the memory, and the like, but here, functional blocks realized by their cooperation are illustrated. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware only, software only, or a combination thereof.

  The dictionary database 30 stores conversion source data and conversion destination data in association with each other. For example, the dictionary database 30 used to input kanji into the application 50 holds kanji readings as conversion source data and kanji as conversion destination data. The dictionary database 30 may hold a zip code as conversion source data, an address as conversion destination data, an English word as conversion source data, and a Japanese translation of English words as conversion destination data. Further, as described later, data marked up in a markup language such as XML may be held as conversion destination data.

  The input receiving unit 12 receives input of conversion source data from the user via the user interface 40. The candidate extraction unit 16 refers to the dictionary database 30 and extracts conversion destination data candidates corresponding to the conversion source data received by the input reception unit 12. When a plurality of conversion destination data candidates are extracted by the candidate extraction unit 16, the order determination unit 18 determines the display order of the plurality of conversion destination data candidates according to a predetermined condition. The candidate display unit 20 displays conversion destination data candidates in accordance with the display order determined by the order determination unit 18 and accepts selection of conversion destination data from the user. The output unit 24 outputs the conversion destination data selected by the user via the user interface 40 to the application 50. Usually, the dictionary database 30 holds data that is easier to input than the conversion destination data as the conversion source data, so that the user can input the conversion destination data to the application 50 by a simpler method. .

  The calibration support unit 22 supports the calibration of the conversion source data received by the input receiving unit 12. For example, when it is presumed that the user has input incorrect conversion source data, an error is pointed out, and correct conversion destination data candidates are extracted from the dictionary database 30.

  The history recording unit 26 records the history of data selected by the user from the candidates for the conversion destination data displayed by the candidate display unit 20 and output by the output unit 24 in the history database 32, and stores data frequently input by the user. learn. This input history is used when the order determination unit 18 determines the display order of candidates.

  The operation switching unit 14 acquires the output destination of the conversion destination data, that is, information related to the input target in the application 50, and based on the acquired information, the candidate extraction unit 16, the order determination unit 18, the candidate display unit 20, the calibration support The operation of the unit 22 is switched. For example, the operation switching unit 14 acquires information related to the data type of the input position from the application 50 and switches the operation of each component so that appropriate input support can be performed according to the data type. The operation switching unit 14 includes rules and algorithms for determining the data type of the input position based on the information acquired from the application 50.

  The operation switching unit 14 may acquire the input position or the surrounding document structure or context from the application 50 and determine the data type of the input position. For example, in the example shown in FIG. 1, the name of the input item displayed on the input form 80 from the application, that is, a character string such as “name” and “surname” is acquired, and the data type of the input position is “ It may be determined that it is a “last name”. In the example illustrated in FIG. 2, the “treatment history DB”, “contraindication”, and “item” may be acquired, and the data type of the input position may be determined to be “a noun related to medical practice”. .

  When the output destination of the conversion destination data is data marked up by a markup language such as XML, the operation switching unit 14 acquires the element name or attribute name of the input position or surrounding data, and the acquired element name Alternatively, the data type may be determined with reference to the attribute name. Alternatively, the markup language schema and input position may be acquired, and the data type may be determined by referring to the acquired schema and position. For example, it is assumed that data input by the input form 80 shown in FIGS. 1 and 2 is stored in the database as XML data shown in FIG. At this time, the operation switching unit 14 may acquire “family” that is an element name of the input position and determine that the data type is “last name”.

  As shown in FIGS. 1 and 2, the operation switching unit 14 is used by the order determination unit 18 to determine the display order of a plurality of conversion destination data candidates based on information related to the output destination of the conversion destination data. Switch conditions. The operation switching unit 14 switches the conditions and algorithms in the order determination unit 18 so that the display order of data estimated to match the data type of the input position is increased.

  For example, the history recording unit 26 may record the input history in the history database 32 for each data type. In this case, the operation switching unit 14 determines the data type of the input position and notifies the order determination unit 18, and the order determination unit 18 receives the input history of the data type notified from the operation switching unit 14 from the history database 32. get. The order determination unit 18 may increase the display order of the candidates selected immediately before by referring to the history acquired from the history database 32, or may increase the display order of the frequently selected candidates. Good. Thus, when entering “last name”, “Masui” and “Sakurai”, which are frequently entered as “last name”, are displayed at the top, and when entering “medical practice”, “medical practice” "Anesthesia" and "Drunkenness" that are frequently input as "" are displayed at the top.

  As another example, the data type of the conversion destination data may be further stored in the dictionary database 30. For example, as kanji candidates corresponding to “Masui”, “anesthetic” may be “therapeutic action” and “Masui” may be “last name” in association with each other. In this case, the operation switching unit 14 determines the data type of the input position and notifies the order determination unit 18, and the order determination unit 18 displays the conversion destination data candidates of the data type notified from the operation switching unit 14. Increase the order. As a result, when entering “last name”, “Masui” and “Sakurai” that should be entered as “last name” are displayed at the top, and when entering “medical practice”, “medical practice” is displayed. “Anesthesia” and “Drunkenness” to be entered are displayed at the top.

  With such a technique, even when input work is performed in a plurality of contexts, appropriate conversion candidates are preferentially displayed according to the context, so that the efficiency of the user's input work can be improved.

  The operation switching unit 14 may set a condition for narrowing down candidates for conversion destination data extracted by the candidate extraction unit 16 based on information regarding the output destination of the conversion destination data. For example, the operation switching unit 14 determines the data type of the input position, and extracts only conversion destination data that matches the data type as a candidate, or preferentially selects conversion destination data that matches the data type. You may switch the conditions and algorithm of the candidate extraction part 16 so that it may extract as a candidate. The candidate extraction unit 16 narrows down candidates for the conversion destination data based on the conditions and algorithm set by the operation switching unit 14. For example, a dictionary database 30 may be provided for each data type, and conversion destination data candidates may be extracted from the dictionary database 30 corresponding to the data type notified from the operation switching unit 14. Thus, only conversion destination data candidates that match the data type are displayed, so that the efficiency of data input by the user can be improved. Further, it is possible to suppress erroneous data input that does not match the data type of the input position.

  The candidate extraction unit 16 may switch the dictionary database 30 to be referred to based on the history of the conversion destination data selected by the user with reference to the history database 32. For example, if there is a feature such as frequently selecting data excluding particles or often selecting a phrase unique to spoken language, the candidate extracting unit 16 stores a dictionary database in which colloquial tone conversion destination data is stored. Candidates are extracted from 30. The operation switching unit 14 may switch the dictionary database 30 with reference to information such as words included in the input document, document structure information, and the like. The candidate extraction unit 16 may infer candidates for the conversion destination data when the user inputs a part of the conversion source data. In this case, the operation switching unit 14 determines the document structure, context, and data of the input position. According to the type or the like, the data indicating the certainty of the conversion destination data is switched, and an appropriate candidate can be estimated according to the document structure or context.

  The operation switching unit 14 may further cause the candidate display unit 20 to display information related to the data type of the output destination based on information regarding the output destination of the conversion destination data. For example, when the data type of the input position is an address, when the candidate display unit 20 displays the address candidate as the conversion destination data candidate corresponding to the postal code received from the user, the map is further displayed. The corresponding position may be displayed. Moreover, you may enable it to input a postal code by selecting a position from a map. Thereby, appropriate input support can be performed according to the data type of the input position, and the convenience of data input can be improved.

  The operation switching unit 14 may switch the operation of the calibration support unit 22 based on information related to the output destination of the conversion destination data. For example, if the conversion destination data corresponding to the conversion source data input by the user is not registered in the dictionary database 30, the proofreading support unit 22 searches the dictionary database 30 assuming that the user has input incorrect data. The correct conversion destination data is estimated and displayed. At this time, conversion destination data can be estimated more accurately by switching the estimation algorithm according to the data type of the input position.

  The operation switching unit 14 may switch the operation of the history recording unit 26 based on information regarding the output destination of the conversion destination data. For example, conversion destination data selected by the user may be recorded for each data type. Further, information such as an input position and a document structure may be recorded in accordance with the history database 32. The history data may be weighted according to the document structure or context of the input position. In this way, the conversion destination data can be estimated more accurately by changing the learning algorithm, the learning result storage location, and the like according to the document structure, context, data type, and the like of the input position.

  As in the example shown in FIG. 4, when the output destination of the conversion destination data, that is, the data of the input position in the application 50 is data marked up by a markup language, the data input device 10 is marked up. The data may be output to the application 50. In this case, the dictionary database 30 includes data marked up in a markup language as candidates for conversion destination data.

  In the above-described example, the patient's last name is stored in the element “family”. Here, a case where XML data as shown in FIG. 5 is stored as a text with ruby will be described as an example. In this case, the dictionary database 30 holds, for example, the XML data shown in FIG. 5 as conversion destination data corresponding to “Masui”. It may be stored in the dictionary database 30 that the XML data is “last name” data.

  In the example shown in FIG. 1, the candidate extraction unit 16 obtains conversion destination data corresponding to “Masui” from the dictionary database 30 in addition to kanji characters such as “Masui”, “Sakurai”, and “anaesthesia”. The XML data shown in FIG. 5 is also extracted as a candidate. When the candidate display unit 20 displays the XML data shown in FIG. 5 as a candidate, the XML data may be displayed as text data. However, in order to make the display easier to understand, the candidate display unit 20 The drawing result of XML data may be acquired from 50, and the acquired drawing result may be displayed. Alternatively, the candidate display unit 20 may delegate the drawing of XML data to the application 50, and the application 50 may directly draw the XML data in the area where the candidate is displayed. In the example of FIG. 1, the text with ruby shown in FIG. 5 is displayed with the kana character “Masui” and the reading kana “Masui” added as ruby. Thereby, XML data can be displayed as a conversion candidate in a display mode that is visually easy to understand.

  If the operation switching unit 14 can refer to the schema by acquiring a schema of the markup language from the application 50 or the like, the candidate extraction unit 16 determines that the markup data extracted as a candidate for the conversion destination data is the schema May be determined, that is, whether it can be inserted at the input position. As a result, it is possible to prevent the input of inappropriate XML data and maintain the validity of the document.

  When the output unit 24 outputs XML data to the application 50, the XML data may be output as text data or may be output as DOM object data. Also, binary data obtained by serializing DOM object data may be output. The output unit 24 may output XML data using an API such as SAX (Simple API for XML).

  In a general XML data editing application, when inserting XML data, a command for inserting an element is selected from commands such as a menu, and an element value and an attribute value are input. However, as described above, if the data input device 10 has a function of outputting XML data, the user can insert the XML data into the document by a simple method in the same manner as inputting text data. Can do. In this way, the data input device 10 not only simply converts Japanese readings into Kanji characters but also inputs them, for example, converts the conversion source data “x” into MathML's “<mi> x </ mi>”. It can be applied to various input operations such as converting to data and inputting.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are also within the scope of the present invention. is there.

  The present invention is applicable to a data input device that converts and inputs data.
