[First embodiment]
FIG. 1 is a block diagram showing a functional configuration of a document conversion system 10 according to an embodiment of the present invention. The document conversion system 10 is an information processing system including the dictionary selection device according to the present invention.

  The document conversion system 10 is a system for converting a part or all of a document using a dictionary. The conversion referred to here is, for example, translation, that is, conversion of words in one language into words in another language, but one word is replaced with another word (synonymous) having a common meaning, or the meaning of a word is And may be presented. For example, the document conversion system 10 translates the whole text of a certain document, and displays the meaning and definition of a word / phrase in a specific part designated by the user (with the original word / phrase).

  The document in the present embodiment means data (file) including character information. The document referred to here may be so-called text data, that is, data including a character string described by a character code (ASCII, UNICODE, etc.), but the character recognition processing using an optical character recognition (OCR) technology It may be image data from which a column can be extracted, or data formed by combining text data and image data. However, when the document conversion system 10 executes a process such as translation on a document including image data, it extracts a character string in advance by a character recognition process.

  Also, the document conversion system 10 manages documents hierarchically by directories. In the present specification, directories are considered to be synonymous with folders. In particular, when a directory is visually represented, it is generally referred to as a folder. However, these designations may differ depending on the file system or OS (Operating System).

  In the document conversion system 10, documents that are related to each other are stored in respective directories. For example, documents stored in the same directory have commonality to document contents (genre, field, author, language, etc.). Also, in the case where the document can be accessed by a plurality of users (subscribers of a certain service, employees of a company, etc.), and the plurality of users are classified into several groups, each group Different directories are assigned as document storage locations for each. In this case, users belonging to the same group have common attributes, such as performing research in a common special field, or sharing a common hobbies and preferences. Each user accesses a directory corresponding to the group to which he or she belongs, and uploads or downloads a document.

  Further, the dictionary in the present embodiment is a set of data stored in association with the first word and the second word. For example, if the dictionary referred to here is an English-Japanese dictionary, the first word is an English word, and the second word is a Japanese word corresponding to the word. The document conversion system 10 is configured to store a plurality of dictionaries, select a dictionary corresponding to a document to be applied, and use the selected dictionary for conversion.

  In the dictionary of this embodiment, a score is assigned to each document or directory. The term "score" as used herein refers to a numerical expression of the appropriateness of using the dictionary in a document. For example, if the score of the first dictionary for a document is higher than the score of the second dictionary for the document, the first dictionary is more suitable for use with the document than the second dictionary. It indicates that it is (probable). Also, the score for the directory indicates the appropriateness of using the dictionary for the documents stored in the directory. Note that the score for a certain document in a certain dictionary does not necessarily match the score for the directory in which the document is stored.

  As shown in FIG. 1, the document conversion system 10 according to the present embodiment includes a document management unit 11, a dictionary management unit 12, a calculation unit 13, a selection unit 14, a conversion unit 15, and an output unit 16. Equipped with The document conversion system 10 may be configured by one computer device, but may be configured by cooperation of a plurality of computer devices (for example, a server device and a client device).

  The document management unit 11 is a means for managing a document. The document management unit 11 manages uploading and downloading of a document in accordance with a user operation. For example, when a plurality of users access a document, the document management unit 11 manages uploading and downloading of the document based on the association between the user and the group (that is, the directory). In this case, when a certain user accesses a document, the document management unit 11 controls to access a directory corresponding to the user.

  The dictionary management unit 12 is a means for managing a dictionary. Further, the dictionary management unit 12 manages, for each dictionary, a score for each document (that is, a stored document) managed by the document management unit 11 and a score for each directory in which each document is stored. .

  The calculation unit 13 is a means for calculating a score. The calculation unit 13 calculates a score for each document and each directory for each dictionary managed by the dictionary management unit 12. In addition, when a document is newly added and stored in a specific directory, the calculation unit 13 newly calculates a score for the document and recalculates a score for the directory. At this time, the calculation unit 13 does not have to recalculate the score for a directory in which the newly added document does not affect the score.

  The selection unit 14 is means for selecting a dictionary used for a document. The selection unit 14 selects one or more dictionaries suitable for use in the document stored in a certain directory, based on the scores of the dictionaries calculated by the calculation unit 13. Alternatively, the selection unit 14 selects a dictionary suitable for use in documents associated with a certain directory. The association referred to here is performed by, for example, a user operation.

  The conversion unit 15 is means for converting a part or all of a document. The conversion unit 15 converts the document to be converted using the dictionary selected by the selection unit 14. The conversion unit 15 may be configured to output a plurality of conversion results using a plurality of dictionaries individually for one document.

  The output unit 16 is means for outputting the conversion result by the conversion unit 15. The output by the output unit 16 means, for example, displaying the conversion result, but may generate a file representing the conversion result and record it or transmit it to another device. For example, the output unit 16 may generate another document as a translation result of a certain document, and save the document in a predetermined file format such as PDF (Portable Document Format).

  FIG. 2 is a block diagram showing a hardware configuration of a translation apparatus 100 which is a specific example of the document conversion system 10. The translation apparatus 100 is a computer apparatus for translating a document from a first language to a second language (here, from Japanese to English). The translation device 100 is realized by, for example, a personal computer, a smartphone, a tablet terminal, or the like. Specifically, translation apparatus 100 includes control unit 110, storage unit 120, input unit 130, output unit 140, and communication unit 150. In addition, the output unit 140 is configured to include the display unit 141.

  The control unit 110 is means for controlling the operation of each unit of the translation apparatus 100. The control unit 110 includes an arithmetic processing unit such as a central processing unit (CPU) and a memory corresponding to a main storage unit, and executes various processes by executing a program. The control unit 110 cooperates with each unit of the translation apparatus 100 to realize functions equivalent to the document management unit 11, the dictionary management unit 12, the calculation unit 13, the selection unit 14 and the conversion unit 15 of the document conversion system 10.

  The storage unit 120 is means for storing data. The storage unit 120 includes a storage medium such as a hard disk and a flash memory, and stores data required by the control unit 110. Specifically, the storage unit 120 stores, in addition to the program executed by the control unit 110, a document, a dictionary, a score, and the like. In the storage unit 120, documents are stored in a state classified by a directory.

  The input unit 130 is means for receiving user input. The input unit 130 may be a keyboard (or a keypad) or a mouse, but in the case where the display unit 141 is a touch screen display, it includes a touch sensor such as an electromagnetic induction method or a capacitance method. obtain. The input unit 130 supplies, to the control unit 110, information (signals) corresponding to the user's operation.

  The output unit 140 is means for outputting information. The display unit 141 is a means for displaying (that is, visually outputting) information. The display unit 141 includes a display panel configured of a display element such as liquid crystal, and displays an image according to an instruction from the control unit 110. In addition to the display unit 141, the output unit 140 may include means (such as a speaker) for reproducing a part or all of the document by voice.

  The communication unit 150 is a unit that communicates with a network or another computer device to transmit and receive data. Communication by the communication unit 150 may be either wired or wireless. The communication unit 150 may receive a document or a dictionary from the outside or may transmit the document to the outside, but is not an essential component for the translation apparatus 100.

  FIG. 3 is a diagram illustrating a document stored in the translation apparatus 100 and its directory structure. In this example, the folder F1 corresponds to the topmost directory. Below the folder F1 (directly below) are folders F2 and F4, and further below the folder F2 is a folder F3. Documents D1 and D2 are stored in the folder F2, and documents D3 and D4 are stored in the folder F3 under the folder F2. Further, documents D5 and D6 are stored in the folder F4, and documents D7, D8 and D9 are stored in the folder F5 under the folder F4.

  Although only the convenient code is shown here for each of the folder and the document, in actuality, a name suitable for the user to distinguish between each other is given. The names of the folder and the document may be given mechanically or may be determined by the operation of the user.

  FIG. 4 is a flowchart showing a method of calculating the score of the dictionary. The score calculated by the process shown in FIG. 4 is a score for each document. When calculating the score for each document, the control unit 110 of the translation device 100 first acquires a dictionary for which the score is to be calculated (step Sa1). The number of events acquired at this time is typically plural, but may be only one.

  After acquiring the dictionary for which the score is to be calculated, the control unit 110 sequentially executes loop processing (loop 1) to be repeated for all the dictionaries and loop processing (loop 2) to be repeated for all the documents (steps Sa2, Sa3) . Specifically, the control unit 110 calculates a score for a certain document of a certain dictionary (step Sa4), and repeats this for all the documents. The control unit 110 determines in step Sa5 whether there is a document whose score is not calculated, and if there is a document whose score is not calculated, executes the processing of steps Sa3 and Sa4, while if there is no document whose score is not calculated End loop processing. Next, when the calculation of the score for each document is completed for a certain dictionary, control unit 110 determines in step Sa6 whether there is a dictionary whose score has not been calculated, and if there is a dictionary whose score has not been calculated, steps Sa2 to Sa5. Repeat the process of

  As a specific calculation method of the score for each document and each directory, for example, the following method can be considered. Here, the score for each document is “(total number of words contained in the document / word in the first language among the words contained in the first language / total number of words in the first language contained in the dictionary) + The total number of words / phrases contained in the document among the words / phrases in the second language / the total number of words / phrases in the second language included in the dictionary).

  FIG. 5 is a diagram showing an example of the dictionary (dictionary A). Here, for convenience of explanation, it is assumed that only two pairs of words are recorded in the dictionary A. However, the actual dictionary may contain more words. There are four words contained in the dictionary A: “document translation” and its parallel translation “document translation”, and “specialized dictionary” and its parallel translation “specialized dictionary”.

  In this case, if a document includes "document translation" and "specialized dictionary" and does not include "document translation" and "specialized dictionary", the score of dictionary A for the document is "1 ( = 2/2 + 0/2) ". On the other hand, in the case where a document includes all of these four words and phrases, the score of the dictionary A for the document is “2 (= 2/2 + 2/2)”. In the case of this calculation method, the maximum value of the score is "2".

  6 to 8 are diagrams showing a method of calculating a score for each directory of the dictionary A. The control unit 110 determines, for each document, whether each of the words included in the dictionary is included. FIG. 6 shows a method of calculating a score related to the term "document translation" included in the dictionary A. In this example, the score (provisional value) of each directory is “(total number of documents including the word / phrase (here, document translation) stored in the directory) / (total number of documents stored in the directory) It is assumed that Here, the "document stored in the relevant directory" also includes a document stored in a lower directory of the relevant directory.

  Here, assuming that "document translation" is included in the documents D1, D2, D3, and D7, the scores of the folders F1, F2, F3, F4, and F5 are "0.44" and "0.75", respectively. , “0.50”, “0.20”, and “0.33”. Here, the value of the score is a value rounded off to two decimal places.

  FIG. 7 shows how to calculate the score for the term "document translation" contained in the dictionary A. Here, it is assumed that the word / phrase is included in the documents D4 and D7. Then, the scores of the folders F1, F2, F3, F4, and F5 are “0.22”, “0.25”, “0.50”, “0.20”, and “0.33”, respectively.

  After calculating these values, the control unit 110 adds the score for "document translation" in each directory and the score for "document translation", and combines them with "document translation" and its parallel translation "document translation". Score for That is, the scores of the folders F1, F2, F3, F4, and F5 are “0.66”, “1.00”, “1.00”, “0.40”, and “0.66”, respectively.

  The control unit 110 executes the same calculation for other words and phrases. FIG. 8 shows the score for the set of “specialized dictionary” and its bilingual “specialized dictionary”. In this example, the scores of the folders F1, F2, F3, F4, and F5 are “0.56”, “0.75”, “0.50”, “0.40”, and “0.33”, respectively. .

  Finally, the control unit 110 calculates the average value of the scores of each set obtained in this way, and uses this as the score for each directory of the dictionary A. In this example, the scores of the folders F1, F2, F3, F4, and F5 are “0.61”, “0.88”, “0.75”, “0.40”, and “0.50”, respectively. . The control unit 110 calculates scores in the same manner for other dictionaries.

  In addition, the calculation method of a score is not limited to the example mentioned above. For example, the score for each document is “total number of words / phrases contained in the document among words / phrases in first language / words contained in the dictionary / total number of words / phrases in first language contained in the dictionary” Instead of the sum of the total number of words / phrases contained in the document / total number of words / languages in the second language included in the dictionary among the words / languages, it may be an average (arithmetic average or geometric average). Further, in the case of calculating the score for each directory, the “document stored in the directory” may not include the document stored in the lower directory of the directory.

  The translation apparatus 100 translates the document using the score thus calculated. Specifically, the translation apparatus 100 selects a dictionary stored in a certain folder or used for a document associated with the folder based on the score of the folder, and presents the translation result to the user. Here, the document associated with the folder refers to the document dragged onto the folder. This document is stored in the folder when it is dropped (i.e., dragged and dropped) after being dragged so as to overlap the folder. That is, the document in the state associated with the folder mentioned here is a document before being stored in the folder.

  FIG. 9 is a view showing a display example of a translation result. When the document icon is dragged onto the folder icon, the translation apparatus 100 selects a dictionary with the highest score for the folder, and displays the translation result of the dictionary by a balloon or the like. The translation result displayed at this time does not have to be the entire translated document, but may be a part such as the beginning. In addition, the translation apparatus 100 may select a plurality of dictionaries having high scores for the dragged folder in the order of scores, and may display the translation results of the respective dictionaries in a comparable manner. In this case, upon receiving an operation of selecting the displayed translation result, translation apparatus 100 may newly generate a document obtained by translating the original document.

  FIG. 10 is a flowchart showing an operation at the time of translation of the translation device 100. When control unit 110 of translation apparatus 100 receives an operation of dragging an icon of a document so as to overlap an icon of a folder (step Sb1), the control unit 110 identifies the folder and identifies a score for each folder in each dictionary (step Sb2). ). In addition, the score of each dictionary shall be calculated in advance.

  The control unit 110 selects a dictionary based on the score specified in step Sb2 (step Sb3), and translates the dragged document using the selected dictionary (step Sb4). When the translation is completed, the control unit 110 causes the display unit 141 to display the translation result (step Sb5). Control unit 110 may read the translation result by synthetic speech instead of the display by display unit 141. Further, the control unit 110 may display the translation result by accepting a specific operation not only for the document dragged into the folder but also for the document already stored in the folder.

  As described above, in the present embodiment, since the score is given to the folder (directory), it is not necessary to give the score in advance to the document itself when translating the document. In the present embodiment, when a document is associated with any folder, the dictionary to be applied to the document is automatically selected (ie, not based on the user's selection). Further, in the present embodiment, when the folder storing the document changes, the dictionary used for the document may also change.

  Further, in the present embodiment, since the dictionary to be used for the document can be selected regardless of the content of the document, when translating a document for which a character string needs to be extracted by the character recognition process, At the stage of selecting the dictionary to be used, it is not necessary to extract character strings from the document.

Second Embodiment
FIG. 11 is a block diagram showing a functional configuration of a document conversion system 20 according to another embodiment of the present invention. The document conversion system 20 is an information processing system including the dictionary selection device according to the present invention. In addition, the document conversion system 20 has common points with the document conversion system 10 illustrated in the first embodiment. In the present embodiment, descriptions of parts in common with the first embodiment will be omitted as appropriate.

  The document conversion system 20, like the document conversion system 10, is a system for converting a part or all of a document using a dictionary. However, the document conversion system 20 is different from the document conversion system 10 in that it presents the user with options of the dictionary to be used for the document before converting the document using the dictionary, and uses the dictionary selected by the user. .

  The document conversion system 20 includes a document management unit 11, a dictionary management unit 12, a calculation unit 13, a selection unit 14, a presentation unit 21, a reception unit 22, a conversion unit 15, and an output unit 16. In the configuration of the document conversion system 20, the document management unit 11, the dictionary management unit 12, the calculation unit 13, the selection unit 14, the conversion unit 15, and the output unit 16 are components of the same reference numerals described in the first embodiment. And have common configurations and functions.

  The presentation unit 21 is means for presenting the dictionary selected by the selection unit 14 to the user as an option. The presentation unit 21 presents the user with options and prompts the user to make a selection. In addition, the presentation part 21 may be comprised so that conversion of a document may be performed, without presenting an option, when the dictionary selected by the selection part 14 is only one.

  The receiving unit 22 is means for receiving an operation of the user. The operation accepted by the accepting unit 22 includes at least an operation of selecting a specific dictionary from the options presented by the presenting unit 21, but may include other operations.

  FIG. 12 is a block diagram showing a configuration of a translation system 200 which is a specific example of the document conversion system 20. As shown in FIG. The translation system 200 is configured to include a document management device 200A and a translation device 200B. The document management device 200A and the translation device 200B are connected via a network such as the Internet or a wireless local area network (LAN).

  The translation system 200 is a so-called client server system, the document management device 200A corresponds to a server device, and the translation device 200B corresponds to a client device. Also, the translation system 200 differs from the translation apparatus 100 of the first embodiment in that a dictionary and a document are shared by a plurality of users. A plurality of translation devices 200B different from each other may be connected to the document management device 200A, or the translation devices 200B may be shared by a plurality of users.

  The translation device 200B has the same hardware configuration as the translation device 100 of the first embodiment. The document management apparatus 200A also has at least a general hardware configuration (a control unit, a storage unit, a communication unit, and the like) as a server device. These units have the same basic configuration and function as the control unit 110, the storage unit 120, and the communication unit 150 of the translation apparatus 100.

  The document management apparatus 200A includes a dictionary management unit 210A, a document management unit 220, a dictionary acquisition unit 230, a calculation unit 240, and a translation information transmission unit 250. The translation device 200B further includes a dictionary management unit 210B, a translation information reception unit 260, a dictionary selection unit 270, and a translation unit 280.

  The dictionary management units 210A and 210B correspond to the dictionary management unit 12 in the document conversion system 20. However, while the dictionary managed by the dictionary management unit 210A is a dictionary usable by any user, the dictionary managed by the dictionary management unit 210B is individually prepared for each user (or group) Dictionary.

  The document management unit 220 corresponds to the document management unit 11 in the document conversion system 20. In the translation system 200, the document is stored in the document management device 200A (instead of the translation device 200B). Also in the translation system 200, documents are stored in the state classified by the directory.

  The dictionary acquisition unit 230 is means for acquiring a dictionary for which score calculation is to be performed. The dictionary acquisition unit 230 acquires the dictionary managed by the dictionary management unit 210B in addition to the dictionary managed by the dictionary management unit 210A.

  The calculation unit 240 is a unit corresponding to the calculation unit 13 in the document conversion system 20. The calculation unit 240 calculates the score for each document and each directory for the dictionary acquired by the dictionary acquisition unit 230.

  The translation information transmission unit 250 is a means for transmitting translation information. Here, the translation information means information indicating a dictionary to be used at the time of translation and its score. When the user of translation apparatus 200B selects a document to be translated, translation information transmission unit 250 selects a dictionary suitable for translating the document based on the score calculated by calculation unit 240. That is, the translation information transmission unit 250 corresponds to the selection unit 14 in the document conversion system 20. When the dictionary management unit 210A stores the dictionary selected as the dictionary suitable for translating the document, the translation information transmission unit 250 transmits the dictionary itself, while the selected dictionary is the dictionary management unit 210B. If it is stored, the identification information (file name etc.) of the dictionary is transmitted.

  The translation information receiving unit 260 is a means for receiving the translation information transmitted by the translation information transmitting unit 250. The dictionary selection unit 270 is a means for displaying a dictionary to be used at the time of translation as an option based on the translation information received by the translation information reception unit 260 and causing the user to select one. That is, the dictionary selection unit 270 corresponds to the presentation unit 21 and the reception unit 22 in the document conversion system 20.

  The translation unit 280 is a unit corresponding to the conversion unit 15 and the output unit 16 in the document conversion system 20. The translation unit 280 translates the document using the dictionary selected by the user. In the present embodiment, the translation unit 280 translates the original document to generate a new document (hereinafter referred to as "translation document").

  FIG. 13 is a sequence chart showing an operation of the translation system 200 at the time of translation. In the present embodiment, the user translates a document stored in a specific directory of the document management apparatus 200A. At this time, the translation device 200B receives an operation to select one of the documents stored in the document management device 200A (step Sc1). Translation apparatus 200B receives a user operation by displaying a list of documents stored in document management apparatus 200A.

  When the user selects a document, the translation device 200B transmits the file name of the document to the document management device 200A (step Sc2). At this time, if there is a dictionary stored in the translation device 200 B, the translation device 200 B transmits the dictionary together. When the document management apparatus 200A receives the file name in step Sc2, the document management apparatus 200A specifies the document selected by the user based on the file name, and specifies the score of each dictionary for the document (step Sc3). The document management device 200A calculates the score in advance for the dictionary stored in the device itself, but calculates the score for the dictionary stored in the translation device 200B after receiving from the translation device 200B. However, the document management device 200A may receive the dictionary stored in the translation device 200B and calculate the score in advance before step Sc2.

  At this time, the score used by the document management apparatus 200A for the evaluation of the dictionary may be either the score of the document or the score of the directory in which the document is stored, or these scores may be added or averaged The score may be used for evaluation.

  The document management apparatus 200A evaluates each dictionary according to the score specified in step Sc3 and selects a dictionary to be presented as an option to the user (step Sc4). The evaluation here may be either absolute evaluation or relative evaluation. That is, the document management apparatus 200A may select a dictionary exceeding a predetermined score, or may select a predetermined number of dictionaries in order of score. After selecting the dictionary suitable for translation in this way, the document management apparatus 200A generates translation information and transmits it along with the document selected by the user (step Sc5).

  When receiving the translation information at step Sc5, the translation device 200B displays the dictionary selected by the document management device 200A as an option (step Sc6). Thereafter, the translation device 200B receives an operation of selecting one of the dictionaries displayed as an option (Step Sc7). When receiving the user's operation, translation apparatus 200B executes translation using the dictionary selected by the user (step Sc8).

  FIG. 14 is a diagram showing a display example of options. The translation device 200B displays such a screen when instructed by the user to translate a document. In this example, the translation device 200B displays the dictionary selected by the document management device 200A together with its score. The user selects one of the displayed dictionaries and instructs the translation device 200B to execute translation.

  The user may select a dictionary other than the dictionary displayed as an option. For example, if there is a dictionary more appropriate than the dictionary displayed as an option, the user may instruct the translation device 200B to translate using the dictionary.

[Modification]
The embodiment of the present invention is not limited to the above-described embodiment. For example, the present invention may be embodied by the aspects described below. In addition, the present invention may be implemented by combining the embodiment described above with one or more modifications, and the matters described in one of the two embodiments may be applied to the other.

(1) The calculation method of the score is not limited to those described in the examples. For example, the score for a document in a certain dictionary may be a value obtained by dividing the number of times the words contained in the dictionary are used in the document (total number) by the total number of words contained in the document. Alternatively, when the score is calculated using a document stored in a certain directory and a document stored in a directory belonging to a lower directory of the directory, the score of the document stored in the upper directory is stored in the lower directory The weighting may be different depending on the score of the document being processed.

  Also, the score of each dictionary may reflect whether or not the user has actually been used for translation when the dictionary is presented (that is, whether an operation to select the dictionary has been performed). . For example, a value corresponding to the number of times selected by the user may be added to the score of each dictionary. This makes the score of the dictionary frequently used by the user higher.

(2) The calculation timing of the score is not particularly limited. The document conversion system 10 (or 20) may calculate (update) the score every time a document or dictionary is newly added, for example, once an hour, once a day, etc. The score may be calculated (updated) at a predetermined time interval. In addition, the document conversion system 10 (or 20) may calculate the score in a time zone in which the load on the system is relatively low (for example, midnight).

(3) Classification of documents may be performed artificially or mechanically. For example, the document conversion system 10 (or 20) may classify documents according to the file name of the document, the language described, the words included in the document, etc., and store the documents in a directory corresponding to each document. In addition, the document conversion system 10 (or 20) may classify the document using the metadata, when the metadata (tag or the like) indicating the attribute of the document is included in the document.

(4) The present invention may be provided in the form of a program for causing a computer to function as the dictionary selection device according to the present invention, a method of selecting a dictionary, and the like in addition to the dictionary selection device and the document conversion system. Further, the program according to the present invention may be provided in a state of being stored in a computer readable recording medium such as an optical recording medium, a semiconductor memory, and the like. Such a program may be made available by being downloaded to a computer device using communication means such as the Internet.
