  FIG. 2 shows that summary data is created (reconstructed) for each character based on the summary data of the entire document attached to the document, and the created summary data is displayed according to the user's character designation. It is explanatory drawing in the case of displaying.

  In FIG. 2, it is assumed that document data (also referred to as electronic book data) D of a novel is read from the memory card 15 by the electronic book reader.

  Summary data of the entire document is added to the document book data D, and this summary data includes information including the history of the characters A to X in the document together with page information.

  The electronic book reader creates individual history summary data Sa, Sb... Sx for each character A to X from the summary data.

  Specifically, the CPU 1 of the electronic book reader extracts phrases related to each of the characters A to X from the entire summary data, and the summary data Sa of the character A is shown in FIG. Arrange the extracted phrases in order.

  Next, a page in which each phrase is described is extracted from the summary data, and as shown in FIG. 3B, page related information Pa that associates each phrase with the page is created.

  When the user designates a character while the electronic book data D is displayed as a document on the display unit 5, the CPU 1 specifies the designated character and the page currently displayed on the display unit 5. Then, the history summary data Sa of the specified character, for example, the character A is extracted from the individual history summary data Sa, Sb... Sx, and in the clauses included in the history summary data Sa. To the specified page (the currently displayed page), in other words, the clauses included in the page that the user is assumed to have already read are extracted with reference to the page related information Pa. . Then, as shown in FIG. 2, the extracted clauses (phrases 1 to 4 in the example of FIG. 2) are displayed on the display unit 5. The history summary data may be displayed on a part of the page currently displayed on the display unit 5 in a balloon state or the like, or the currently displayed page may be temporarily deleted and displayed. The display form is not limited.

  In this embodiment, the character specified by the user is specified by the user touching the character string W in the document displayed on the display unit 5, and the CPI 1 detects the touched portion, and the content of the character string is detected. It is performed by discriminating. This point will be described later. The character string W may be a word indicating the character itself, or may be a sentence partially including the character.

  In this way, contents (for example, a history) related to one or more appearances appearing in the document are extracted from the summary data of the entire document, and the extracted contents and the contents in the document in which the contents are described are extracted. Individual summary data is created for each appearance in association with the page. When the user specifies an appearance in the document, the specified appearance and the currently displayed page are identified and associated with each page from the individual summary data of the identified appearance to the identified page. The contents related to the displayed appearance are displayed on the display unit 5.

  Therefore, for example, even if a user reads novels that appear one after another in multiple appearances, the contents of the characters can be immediately viewed by looking at the contents related to the displayed appearances. Can understand and can smoothly read and understand sentences.

  FIG. 4 is a flowchart showing a process of creating (reconstructing) the character history summary data. Note that the processing shown in the flowcharts in FIG. 4 and thereafter is executed by the CPU 1 of the electronic book reader operating according to the operation program recorded in the ROM 3 or the like.

  In FIG. 4, in step S1, summary data of the entire book (document) is read. In step S2, proper nouns (characters) are extracted, and in step S3, phrases related to proper nouns extracted from the summary data of the entire book are extracted.

  In step S4, related page information of the book is added to the extracted phrase to obtain individual history summary data.

  FIG. 5 shows creation (reconstruction) of correlation data indicating the correlation with other characters for each character based on the correlation data indicating the correlation between the plurality of appearances appearing in the document as a whole. And it is explanatory drawing in the case of displaying the produced | generated correlation data according to designation | designated of a user's character. It is assumed that correlation data indicating the correlation of the entire document is attached to the document in advance.

  In FIG. 5, it is assumed that an electronic book reader reads electronic book data D of a novel from the memory card 15.

  The electronic book data D is added with correlation data indicating the correlation of a plurality of characters in the entire document, and the correlation data includes information including the correlation of characters A to X in the document. Included with page information.

  The electronic book reader creates individual correlation data indicating the correlation between each of the characters A to X and other characters from the correlation data.

  Specifically, the CPU 1 of the electronic book reader extracts a phrase indicating the correlation for each of the characters A to X from the entire correlation data. For example, for the character A, as shown in FIG. 5, the relationship 1 (R1) with the character B, the relationship 2 (R2) with the character C, and the relationship 3 (R3) with the character D are shown. A phrase indicating the correlation is extracted.

  Next, a page in which each phrase is described is extracted from the entire correlation data, and page-related information Pa that associates each phrase with the page is created as shown in FIG.

  When the user designates a character while the electronic book data D is displayed as a document on the display unit 5, the CPU 1 specifies the designated character and the page currently displayed on the display unit 5. Then, the correlation data of the specified character, for example, the character A is extracted from the correlation data of each character, and the specified page (currently displayed) is selected from the correlations included in the correlation data. In other words, the correlation included in the page that is presumed that the user has already read is extracted with reference to the page related information Pa. Then, the extracted correlation is displayed on the display unit 5. In the example of FIG. 5, since correlation 3 (R3) has not yet been clarified up to the currently displayed page, only correlations 1 (R1) and 2 (R2) are displayed.

  As described above, the correlation between the appearance material and the other appearance materials is extracted from the correlation data indicating the correlation of the plurality of appearance materials appearing in the document as a whole, and the extracted correlation and the correlation are extracted. Is associated with the page in the document in which is described, and individual correlation data is created for each appearance. When the user specifies an appearance in the document, the specified appearance and the currently displayed page are specified, and each page from the individual correlation data of the specified appearance to the specified page is identified. The display unit 5 displays the correlation between the appearances associated with the item and other appearances.

  Therefore, for example, even if the user reads a novel in which characters appearing one after another, etc., read in multiple days, if the correlation between the displayed characters and other characters is seen, the characters Can immediately understand the relationship, and can read the text smoothly.

  FIG. 7 is a flowchart showing a process of creating (reconstructing) correlation data indicating a correlation with other characters for each character.

  In FIG. 7, in step S11, the correlation data of the characters of the entire book (document) is read. In step S12, proper nouns (characters) are extracted, and in step S13, phrases (correlation data) related to the characters extracted from the correlation data of the entire book are extracted.

  In step S14, the related page information of the book is added to the extracted phrase to obtain individual correlation data for each character.

  FIG. 8 is a flowchart showing display target data specifying processing executed when the user designates a character.

  In step S21, it is determined whether or not a predetermined operation by the user has been performed on the displayed character string. If the predetermined operation is executed (YES in step S21), the page information currently displayed on the display unit 5 is acquired in step S22, the coordinate information in the page is acquired in step S23, and the process proceeds to step S24. . If the predetermined operation is not executed (NO in step S21), the process ends as it is.

  In step S24, the character string designated by the user in a predetermined operation is specified from the acquired page information and coordinate information. In step S25, display request information for displaying history summary data or correlation data is generated for the characters included in the specified character string. In step S26, the generated display request is output.

  For example, as shown in FIG. 9, the predetermined action by the user performed on the displayed character string is that the user touches the character string. The touched position is detected, and the coordinate information of the position is obtained. Based on the character string touched by the user, the character is identified. The touch position may be detected by the user tracing the character string a plurality of times (for example, twice).

  FIG. 10 is a flowchart showing an information display process when displaying the history summary data or the correlation data for the identified character.

  In FIG. 10, in step S <b> 31, it is determined whether or not there is a display request in another process executed by the CPU 1. If there is a display request (YES in step S31), display request information is acquired from the process that issued the display request in step S32, and in step S33, the display target character included in the display request information and the current display are displayed. Information such as the inside page is acquired, and the process proceeds to step S34. If there is no display request (NO in step S31), the process ends as it is.

  In step S34, based on the acquired information, the history summary data or correlation data of a predetermined character as display data is masked to hide the data described in the page after the currently displayed page. In step S35, the masked display data is displayed on the display unit 5 and then the process ends.

  FIG. 11 shows that when the summary data is not attached to the electronic book data, the summary result is obtained by using known summary creation software (sentence summary engine) installed in the electronic book data. It is explanatory drawing in the case of producing the personal history summary data of a character based on it.

  In FIG. 11, an analysis sentence 102 that is electronic book data is input, and an extraction keyword 103 that is summary target information such as characters and a summary range 104 that indicates a page range for which a summary is to be created are input based on a user operation. Then, the text summarization engine 101 creates a summary (summary of the entire document) of the input extracted keyword for the summary target page in the analysis text 102 and outputs it as a summary result 105.

  FIG. 12 is a flowchart showing a process for obtaining a summary result using the sentence summarization engine.

  In step S41, it is determined whether a predetermined operation has been performed on the electronic book reader and a summary creation request has been made for specific electronic book data. If there is a summary creation request (YES in step S41), in step S42, a summary target is acquired based on the user's input, and in step S43, a summary target page is acquired based on the user's input, and then to step S44. move on. In step S41, if there is no summary request (NO in step S41), the process ends.

  In step S44, the acquired summarization target information and summarization target page are input to the text summarization engine as an extraction keyword and a summarization range, respectively. In step S45, the summary result in the input electronic book data is acquired as summary data, and the process ends. Using the summary data, the electronic book reader creates history summary data for each individual character as described above.

  Note that the text summary engine may be mounted on another external device instead of the electronic book reader. In this case, the electronic book reader may acquire summary data from another external device, and create history summary data for each character based on the acquired data.

  Further, correlation data for the entire document may be created using the above-described text summarization engine or software capable of creating correlation data for the entire document indicating the correlation between multiple appearances.

  FIG. 13 is an explanatory diagram when the display content is selectable.

  In FIG. 13, when a user performs a predetermined operation on the screen of the display unit 5 on which a document is displayed and a character is detected and detected, information displayed on the specific person can be selected. Thus, a screen showing the selection menu M is displayed on the display unit 5. For example, as the selection menu M, a selection menu such as the history summary data of the character A, the relationship between the character A and the character B, the relationship between the character A and the character C, and the like are displayed. When the menu is selected, the selected content is displayed.

  By the way, in the above embodiment, as a method of identifying a character by detecting a character string designated by a user in a displayed sentence, a touch position when the user touches the screen is detected, and a display page and a touch position are detected. Although the character string is specified from the coordinates of, etc., other methods can be adopted.

  For example, the voice when the user reads the character string may be captured by the microphone 17 and the voice signal may be recognized by the voice recognition unit 19 to identify the character string and the character.

  Alternatively, the movement of the line of sight when the user reads the character string may be coordinate-recognized by the line-of-sight recognition technique, and the character string when the line-of-sight movement matches a preset movement may be detected and specified.

  In the above embodiment, the case has been described in which each character's history summary data and correlation data are separately created and displayed, but each character's history summary data and correlation data are both created, When a character is designated, the history summary data and correlation data for the character may be displayed on the display unit 5.

  Moreover, it is not limited to the history summary data or the correlation data, and may be any data on the contents related to the characters.
