  FIG. 2 is a diagram illustrating examples of original text, translated text, and word correspondence information. The automatic translation unit 11 inputs the original text D11. The automatic translation unit 11 translates the original text described in the original text D11 and outputs the translated text D21 and the word correspondence information D22. In the figure, the original text described in the original text D11 includes a half-width space representing a word break, but the original text D11 input to the automatic translation unit 11 includes information representing a word break. You don't have to. When the source text D11 does not include information representing a word break, the automatic translation unit 11 may add information representing a word break or a word position of each word in the original text D11. The word correspondence information D22 is information in which a number indicating the position of the word in the original sentence is associated with a number indicating the position of the word in the translated sentence. In the figure, the position of the word is represented by the number of words from the beginning of the sentence when the position of the first word is 0. For example, “3-5” indicates that the word “prefecture” at the third position in the original text corresponds to the word “Prefecture” at the fifth position in the translated text. Based on the correspondence indicated by the word correspondence information D22, the information output unit 14 converts the word “prefecture” at the third position in the original sentence indicated by the input original text D11 into the translated sentence indicated by the translated sentence text D21. The word “Prefecture” at the fifth position can be acquired to generate translation information.

  Note that the information output unit 14 may select a word corresponding to a content word based on information such as the part of speech among words in the original sentence, and set only the selected word and its translation as translation information. Thereby, even a word with word correspondence can be made not to present a translated word in accordance with the purpose and convenience.

  FIG. 3 is a diagram illustrating a data flow in the reading comprehension support information generation unit 10. The automatic translation unit 11 and the score acquisition unit 12 input Japanese text. The automatic translation unit 11 acquires partial translation information by using, as translation result information, English translation text obtained as a result of translation of the Japanese text, and word correspondence information indicating the correspondence between the words in the Japanese text and the words in the English text. To the unit 13. The automatic translation unit 11 may further output the original text to the partial translation information acquisition unit 13. The score acquisition unit 12 reads the score of each word included in the Japanese sentence from the vocabulary difficulty level score dictionary which is dictionary data in which the score of each Japanese word is registered. The score acquisition unit 12 may acquire a score from dictionary data stored in an external device connected to the reading support information generation unit 10 via a network. The score acquisition unit 12 outputs score information in which the score of each word in the Japanese sentence is set to the information output unit 14. Below, the case where it represents that a difficulty level is so high that a score is large is demonstrated to an example.

  Instead of using dictionary data, a method of calculating a score so that the difficulty level of a word having a low appearance frequency in the corpus can be increased. Specifically, the score acquisition unit 12 counts the number of appearances of each word included in corpus data prepared in advance, and assigns a stepwise score to each word so that the difficulty level increases as the number of appearances decreases. Give. The score acquisition unit 12 acquires the score calculated in this way. The corpus data can be a set of arbitrary document data.

  Alternatively, there is a method of calculating a word score based on a difference in appearance frequency in corpora of different difficulty levels. For example, a set of document data such as easy news for children and foreigners is set as first corpus data, and a set of document data such as news for general use is set as second corpus data. Alternatively, a set of general-purpose document data is set as first corpus data, and a set of document data for professionals is set as second corpus data. The score acquisition unit 12 calculates the appearance probability of each word in each of the first corpus data and the second corpus data. The score acquisition unit 12 assigns a low difficulty score to words whose appearance probability in the first corpus data is higher than the appearance probability in the second corpus data, and the appearance probability in the second corpus data is the first. A word having a higher difficulty level is assigned to a word having a higher probability of appearance in the corpus data. The score acquisition unit 12 classifies the difficulty level by comparing the appearance probability in the first corpus data with the appearance probability in the second corpus data, and among these classifications, the appearance probability in the first corpus data You may give a score in steps so that it may become higher difficulty, so that is low.

  The partial translation information acquisition unit 13 generates partial translation information in which a word string included in a Japanese sentence is associated with a partial translation that is a word string in an English sentence corresponding to the translation of the word string. Based on the word correspondence information, the partial translation information acquisition unit 13 can obtain a correspondence between a Japanese word string having a different unit of length, such as a phrase or a clause, and a corresponding English word string, based on the word correspondence information. . For example, the partial translation information acquisition unit 13 specifies a part in which the corresponding range is continuous in both Japanese and English based on the word correspondence information, so that a Japanese word string having a different unit of length is used. Get the correspondence between and the English word string. Here, the partial translation information acquisition unit 13 generates partial translation information for each of a phrase-unit word string and a clause-unit word string. The partial translation information acquisition unit 13 outputs the original text, translation text, word correspondence information, and partial translation information to the information output unit 14.

  The information output unit 14 selects a word for which translation information is to be generated from words included in the Japanese sentence. For example, the information output unit 14 selects a part-of-speech word that can be a content word such as a noun, a verb, an adjective, an adverb, and a number as a word for which translation information is to be generated. The information output unit 14 is based on the word correspondence information output from the automatic translation unit 11, and the word of the content word in the Japanese sentence and one or more words in the English sentence indicated by the word correspondence information to correspond to the word Translated word information associated with the translated word is generated. The information output unit 14 may add part-of-speech information of each word to the translated word information or score information. When the automatic translation unit 11 outputs a plurality of translations for each word in the Japanese sentence, the information output unit 14 may set the plurality of translations in the translation information. The information output unit 14 outputs the reading support information including the original text, the translation text, the translation information, the partial translation information, and the score information to the reading support information storage unit 20. In addition, when the reading comprehension support information storage unit 20 can acquire the original text from other than the reading comprehension support information generation unit 10, the original text may not be included in the reading support information.

  FIG. 4 is a diagram illustrating a data flow in the reading comprehension support information storage unit 20. The information acquisition unit 21 acquires reading support information from the reading support information generation unit 10. The information acquisition unit 21 acquires translated word information from the reading comprehension support information and stores it in the translated word information storage unit 23. The information acquisition unit 21 acquires score information from the reading support information, and stores a score of each word in the Japanese sentence indicated by the score information in association with a word in the translation information stored in the translation information storage unit 23. Stored in the unit 24. The information acquisition unit 21 acquires partial translation information from the reading support information and stores it in the partial translation information storage unit 25. The information acquisition unit 21 reads the original text and the translated text corresponding to the original text from the reading support information, and stores them in the translated text storage unit 26 in association with each other. The reading comprehension support information storage unit 20 may acquire the original text from other than the reading comprehension support information.

FIG. 5 is a diagram illustrating a data flow in the reading support information presentation unit 30.
The word string level adjustment unit 33 acquires a word string level indicating how long a word string for which translations are collectively displayed is used as a unit. For example, the word string level adjustment unit 33 acquires the word string level to be set through an interface such as a slider. When the word string level is set to be small so as to shorten the word string, the word string level adjustment unit 33 sets the unit of the word string to the length of a phrase. When the word string level that makes the word string longer than the phrase is set, the word string level adjustment unit 33 sets the unit of the word string to a length of about a clause. When the word string level that makes the word string the longest is set, the word string level adjusting unit 33 sets the word string unit as one sentence. The original sentence presentation unit 34 presents the original sentence of the Japanese sentence in such a manner that the word string unit corresponding to the word string level set by the word string level adjustment unit 33 can be visually recognized.

  The translated word display level adjustment unit 35 acquires a display level that is the amount or difficulty level of words that the user wants to display the translated word. The user inputs a desired display level through the input unit 31. The translated word display level adjustment unit 35 reads the translated word information to which the score information is added from the translated word information storage unit 23 and the score storage unit 24. The translated word display level adjustment unit 35 selects, from the words included in the translated word information, an amount of words corresponding to the acquired display level or a difficult word to be displayed, based on the score.

  For example, the translated word display level adjustment unit 35 associates the display level with a screen display score that is a threshold value of a score used when selecting a word. The translated word display level adjustment unit 35 converts the acquired display level into a screen display score. The translated word display level adjustment unit 35 selects a word having a score equal to or higher than the screen display score among the words included in the translated word information as a translated word display target. Or the translation display level adjustment part 35 may select the word of a score below a screen display score among words contained in translation information as a translation display object. When a word with a score equal to or higher than the screen display score is to be displayed as a translated word, the screen display score is increased as the display level of the word to display the translated word is smaller, and a word with a score lower than the screen display score is to be displayed as a translated word. In this case, the screen display score is lowered as the display level is smaller in the amount of words for displaying the translated word.

  Alternatively, the translated word display level adjustment unit 35 may associate the display level with the ratio of words to be translated words in advance. The translated word display level adjustment unit 35 converts the acquired display level into a ratio of words to be translated. The translated word display level adjusting unit 35 is arranged in order from the word with the highest score, so that the word of the ratio closest to the ratio obtained by the conversion is the translated word display target among all the words set in the translated word information, or Select the words to be displayed in order from the word with the lowest score.

  The translated word presenting unit 36 presents the translated word of the word selected by the translated word display level adjusting unit 35. That is, the translated word presentation unit 36 displays the translated word of the word in the vicinity of each word selected by the translated word display level adjustment unit 35 among the words included in the original text displayed on the display unit 32. The translated word presenting unit 36 acquires the translated word of the word selected by the translated word display level adjusting unit 35 from the translated word information read from the translated word information storage unit 23. The translated word presentation unit 36 may display a word score and a part of speech in addition to the translated word. When the information output unit 14 generates translation information by associating a plurality of translations with each word in the Japanese sentence, the translation presentation unit 36 may display a plurality of translations. Whether only the translation in the translation corresponding to the word or a plurality of translations is displayed in the vicinity of the word in the original sentence may be set according to the setting by the user.

  When the user selects a word string of a Japanese sentence using the input unit 31, the word string translation presentation unit 37 causes the display unit 32 to display a translation corresponding to the selected word string. When the word string level is a clause or a phrase, the word string translation presentation unit 37 reads and presents the partial translation of the English sentence corresponding to the selected word string from the partial translation information stored in the partial translation information storage unit 25. . When the word string level is a sentence, the word string translation presentation unit 37 reads and presents the English sentence corresponding to the selected Japanese sentence from the translated sentence text stored in the translation sentence storage unit 26.

  Note that each piece of information stored in the reading support information storage unit 20 is generated by the reading support information generation unit 10. However, when such information can be acquired by using other means, the reading support system 1 The reading support information generating unit 10 may not be included. For example, the reading support information may be manually generated and stored in the reading support information storage unit 20.

  Next, an example of a screen displayed by the reading support system 1 will be described. 6 to 11 are diagrams showing examples of screen display on the display unit 32. In these screen display examples, the display level represents the amount of words that the user wants to display.

FIG. 6 shows a display example when the word string level is set as a unit of clause and the display level is set to the lowest level.
As shown in the figure, the original text presentation unit 34 displays the original text in the display area A1 in the screen displayed by the display unit 32. Here, since the word string level is set to the unit of the clause, the original sentence presentation unit 34 displays the word string in the original sentence by dividing it into the unit of the clause. In the figure, the original sentence presentation unit 34 displays a word string that is one delimiter so as to be surrounded by one frame F1. The frame F1 may be displayed so that the outer periphery is surrounded by a line, the background in the frame F1 may be displayed with a color or pattern different from the background of the entire display area A1, or a combination thereof is displayed. May be. Moreover, the original sentence presentation part 34 may display an original sentence in the other aspect which can visually recognize the division | segmentation of a word string instead of enclosing with a frame. For example, the original text presentation unit 34 may insert a symbol, character, or figure representing a delimiter such as “/” between the delimited word strings, or may change the color of the characters in adjacent word strings. An underline may be displayed for each break.

  The slider B1 is a user interface for inputting a display level. Here, a case where a word having a higher score than the screen display score corresponding to the display level is displayed will be described as an example. The user operates the slider B1 using the input unit 31 to set the display level. Thus, from a state where no translation is displayed (FIG. 6), only a translation of a word having a high score (a word having a high difficulty level) (FIG. 7 described later), a state where all the translations are displayed (a diagram described later). 8) can be changed. In the figure, the user sets the smallest amount of words to be translated. In this case, the translated word presentation unit 36 does not display the translated word.

  FIG. 7 shows a screen display example when the display level is set between the lowest level and the highest level. This figure shows a display example in the case where a word having a score equal to or higher than the screen display score corresponding to the display level set by the user is included in the original text to some extent. For example, the display is performed by the slider B1 in FIG. The example of a screen display when the level is set between the lowest level and the highest level is shown. The translated word presenting unit 36 displays a translated word of the word in the vicinity of a word having a high degree of difficulty among the words in the original sentence. In the figure, the translated word is displayed above the word in the original text, but it may be displayed below or displayed on the right side of the word surrounded by parentheses. In the figure, the word and the translation of the word are displayed so as to be surrounded by one frame F2. The frame F2 may be displayed by surrounding the outer periphery with a line, and the background in the frame F2 may be displayed by setting the background or the background of the entire display area A1 or a color or pattern different from the background of the frame F1. You may display by the combination of. In the figure, the frame F2 does not fit within the frame F1, but as shown in FIG. 10 described later, the height of the frame F1 is set higher than the height of the frame F2 so that the frame F2 fits within the frame F1. It may be displayed. In addition, when the display width of the translated word is long, it may be displayed with a wide space between characters of the original sentence, such as evenly allocating according to the size of the frame F2.

  FIG. 8 shows a screen display example when the display level is set between the highest levels. The figure shows a display example when the user sets a high display level so that many words having a score equal to or higher than the screen display score corresponding to the display level are included in the original text. This figure is an example that is displayed when, for example, the slider B1 is set to the highest display level in FIG. 6 or FIG. As shown in the figure, when the display level is set high, the number of target words for displaying translated words increases as compared to FIG.

  As shown in FIGS. 7 and 8, the reading comprehension support system 1 simultaneously displays the translated words of a plurality of words in the original sentence in the vicinity of the words in the original sentence, so that the user grasps the correspondence between the words and the translated words. It is easy to display translated words with a good list.

  FIG. 9 shows a screen display example when displaying a partial translation. In FIG. 8, a frame F1 in which a word string for which a user wants to display a partial translation is displayed with a mouse or the like, or a frame F2 in which a word included in a word string for which a partial translation is to be displayed is displayed. Click to specify a word string. The word string translation presentation unit 37 displays a partial translation of the designated word string in the vicinity of the designated word string. Hereinafter, the three consecutive frames F1 are referred to as frames F1-1, F1-2, and F1-3.

  When the user clicks in the frame F1-1, the word string translation presentation unit 37 performs a line break between the frame F1-1 and the next frame F1-2. The word string translation presentation unit 37 displays a partial translation of the word string in the frame F1-1 between the line in which the frame F1-1 is displayed and the line in which the next frame F1-2 is displayed. Insert F3-1.

Further, when the user clicks in the frame F1-2, the word string translation presentation unit 37 performs a line break between the frame F1-2 and the next frame F1-3. The word string translation presentation unit 37 displays a partial translation of the word string in the frame F1-2 between the line in which the frame F1-2 is displayed and the line in which the next frame F1-3 is displayed. Insert F3-2.
In this way, since the reading comprehension support system 1 displays the partial translation in the vicinity of the original sentence word string, the correspondence between the original sentence word string and the partial translation becomes clear and easy to understand.

  A close button B2 is displayed in the frame F3-1 and the frame F3-2. When the user clicks the close button B2, the word string translation presentation unit 37 deletes the display of the frame F3-1 or the frame F3-2 including the close button B2. For example, when the user clicks the close button B2 in the frame F3-2, the word string translation presentation unit 37 deletes the display of the frame F3-2 and does not perform a line break after the frame F1-2. 3 is displayed.

  FIG. 10 is a diagram illustrating a screen display example when the word string level is a sentence. When the word string level is a sentence, the original sentence presentation unit 34 displays one sentence in the frame F1. When the user designates one sentence with a mouse or the like, the word string translation presentation unit 37 displays the designated translated sentence in the vicinity of the original sentence. In the figure, the word string translation presenting unit 37 makes a line break between a frame F1 containing one designated sentence and a frame F1 containing the next one sentence, and a frame containing one designated sentence. A frame F3 for displaying a specified translated sentence is inserted in a line between F1 and a frame F1 including the next sentence. The display change when the close button B2 in the frame F3 is clicked is the same as described above.

  As shown in FIG. 9 and FIG. 10, the reading comprehension support system 1 displays a partial translation or a translation corresponding to a word string in the original sentence in the vicinity of the word string. The correspondence with translation can be presented in an easy-to-understand manner.

  FIG. 11 is a diagram illustrating another screen display example when the word string level is a sentence. The original sentence presentation unit 34 displays one sentence in the frame F1, and when the user designates one sentence with a mouse or the like, the translated sentence of the one sentence is displayed in the translation display area A2 outside the display area A1. . The word string translation presentation unit 37 displays the frame F1 of the word string displaying the translated sentence with a different color line or background color from the frame of the other word string, or the original sentence is different from the other original sentence. It may be displayed in color. By displaying in this way, even if the translation of the word string is displayed, the display layout of the original text in the display area A1 can be prevented from being changed.

Next, the operation of the reading comprehension support system 1 will be described.
FIG. 12 is a flowchart showing the operation of the reading comprehension support system 1.
First, the reading comprehension support system 1 acquires an original text in which a Japanese sentence is described (step S105). For example, the user may input the original text using the input unit 31, or may acquire the original text of the storage location or file name specified by the user using the input unit 31.

  The automatic translation unit 11 of the reading support information generation unit 10 translates the Japanese sentence of the original text, and outputs the English translation text and word correspondence information obtained as a result of the translation to the partial translation information acquisition unit 13 together with the original text. (Step S110). The score acquisition unit 12 acquires the score of the word included in the Japanese sentence, and outputs score information in which the score of each acquired word is set to the information output unit 14 (step S115). The partial translation information acquisition unit 13 generates partial translation information in which a word string included in a Japanese sentence is associated with a partial translation that is a word string in an English sentence corresponding to the translation of the word string (step S120). . The partial translation information acquisition unit 13 outputs the original text, translation text, word correspondence information, and partial translation information to the information output unit 14.

  The information output unit 14 selects a part-of-speech word as a content word from words included in a Japanese sentence, and selects the selected word and one or more words in the English sentence associated with the word by the word correspondence information. Translated word information associated with a certain translated word is generated. The information output unit 14 outputs the reading support information including the original text, the translated text, the translation information, the partial translation information, and the score information to the reading support information storage unit 20 (step S125).

  The information acquisition unit 21 of the reading support information storage unit 20 stores each information included in the reading support information input from the reading support information generation unit 10 in the storage unit 22 (step S130). That is, the information acquisition unit 21 stores the translated word information in the translated word information storage unit 23 and stores the score of each word in the Japanese sentence in the score storage unit 24. Furthermore, the information acquisition unit 21 stores the partial translation information in the partial translation information storage unit 25, and stores the original text and the translation text corresponding to the original text in the translation sentence storage unit 26 in association with each other.

  The word string level adjusting unit 33 causes the display unit 32 to display a user interface for inputting a word string level indicating how long a word string is used to divide a sentence and displaying a translation. For example, the word string level adjustment unit 33 displays an interface such as a slider on the display unit 32. The user operates the user interface with the input unit 31 and inputs a desired word string level. The word string level adjustment unit 33 acquires the word string level desired by the user through the user interface (step S135). In the case of the first loop process, the word string level adjustment unit 33 may acquire a default word string level. The original sentence presentation unit 34 presents the original sentence on the display unit 32 by dividing the word string unit according to the word string level acquired by the word string level adjustment unit 33 (step S140).

  The translated word display level adjustment unit 35 causes the display unit 32 to display a user interface for inputting a display level that is a level or a difficulty level of a word desired to be translated. The user operates the user interface with the input unit 31 and inputs a desired display level. The translated word display level adjustment unit 35 acquires the display level input by the user through the user interface (step S145). In the case of the first loop process, the translated word display level adjustment unit 35 may obtain a default display level. The translated word display level adjustment unit 35 selects a word in the original text having a score equal to or higher than the screen display score corresponding to the display level acquired by the translated word display level adjustment unit 35. The translated word presenting unit 36 presents the translated word of the word selected by the translated word display level adjusting unit 35 in the vicinity of the word (step S150). The translated word presentation unit 36 may display a word score and a part of speech in addition to the translated word.

  The word string translation presentation unit 37 determines whether the user has selected a Japanese word string by the input unit 31 and has input a display instruction for translation of the word string (step S155). When it is determined that the word string translation display instruction has been input (step S155: YES), the word string translation presentation unit 37 presents the translation of the selected word string (step S160). When the word string level is a phrase or a clause, the word string translation presentation unit 37 acquires and presents a partial translation corresponding to the selected word string from the partial translation information. When the word string level is a sentence, the word string translation presentation unit 37 acquires a translation sentence corresponding to a sentence composed of the selected word string from the translated sentence text and presents it.

  When it is determined that the word string translation display instruction has not been input (step S155: NO), or after step S160, the word string translation presentation unit 37 performs the process of step S165. That is, the word string translation presentation unit 37 determines whether or not the user has selected translation of the displayed word string by the input unit 31 and has input display erasure (step S165). When the word string translation presentation unit 37 determines that the display deletion of the translation has been input (step S165: YES), the word string translation presentation unit 37 deletes the display of the selected translation (step S170).

  When the word string translation presentation unit 37 determines that the display deletion of translation has not been input (step S165: NO), or after the process of step S170, the translated word display level adjustment unit 35 performs the process of step S175. . That is, the translated word display level adjustment unit 35 determines whether or not the user has operated the user interface with the input unit 31 to change the display level (step S175). When the translated word display level adjustment unit 35 determines that the display level has been changed (step S175: YES), the translated word display level adjustment unit 35 repeats the processing from step S145. On the other hand, if the translated word display level adjustment unit 35 determines that the display level has not been changed (step S175: YES), the word string level adjustment unit 33 has the user input a change in the word string level through the input unit 31. It is determined whether or not (step S180). When the word string level adjustment unit 33 determines that a change in the word string level has been input (step S180: YES), it repeats the processing from step S135.

  When the word string level adjustment unit 33 determines that the change in the word string level has not been input (step S180: NO), the reading support information presentation unit 30 causes the end event such as the user to input the end through the input unit 31. Whether or not has occurred is determined (step S185). When it is determined that the end event has not occurred (step S185: NO), the reading support information presentation unit 30 repeats the process from step S155. When it is determined that the end event has occurred (step S185: YES), the reading support information presentation unit 30 ends the process.

  In addition, the reading comprehension support system 1 may be executed by changing the order of the above processes as appropriate, or may be executed in parallel. For example, the reading support information generating unit 10 may perform the processing of Step S110 and Step S120 and the processing of Step S115 in parallel, or may perform the order. Moreover, the reading comprehension support information presentation unit 30 may perform the process of step S140 and the process of step S145 by switching. In addition, the reading comprehension support information generation unit 10 performs part or all of the processes in steps S155 to S160, the processes in steps S165 to S170, the processes in step S175, and the processes in step S180 in parallel. Alternatively, the order may be changed.

  Note that the user may input a screen display score instead of the display level. The translated word display level adjustment unit 35 performs the same processing as described above using the input screen display score.

  In addition, the translated word display level adjustment unit 35 selects the word to be translated based on the word score, but may select the word to be translated based on the part of speech of the word. In this case, the translated word display level adjustment unit 35 associates in advance the display level that represents the amount of words to be translated and that is desired by the user with the part of speech, and converts the display level input by the user into the part of speech. The number of parts of speech to be displayed is reduced as the display level has a smaller amount of words to be translated, and the number of parts of speech to be displayed is increased as the display level has a larger amount of words to be translated. The translated word display level adjusting unit 35 selects a word with a part of speech obtained by converting the display level among words included in the translated word information as a translated word display target. Instead of the score representing the difficulty level, the translated word display level adjustment unit 35 can perform the same process as described above by assigning the translated word information with a score representing the part of speech.

  Further, the user may input information on the part of speech of the word for which the translation is desired to be displayed by the input unit 31. The translated word display level adjustment unit 35 selects a word of the part of speech that has been input from the words included in the translated word information, and presents the translated word of each selected word in the vicinity of the word.

  FIG. 13 shows an implementation example of the reading comprehension support system 1. In the figure, a configuration example when the reading support system 1 is realized by a client / server system is shown. The reading comprehension support system 1 includes a reading comprehension support information providing device 5 that is a server computer and a reading comprehension support device 7 that is a client terminal.
