  The reference content DB 21 holds related reference content for each of a plurality of important words appearing in the electronic book. The reference content DB 21 holds, for example, reference content that is generally referred to from a plurality of electronic books. In the case of reference content that is generically referenced from a plurality of electronic books, the amount of content tends to increase. In the embodiment of the present invention, even a reference content with a large amount of content is displayed so as not to prevent the user from reading the text content.

  FIG. 4 is a diagram illustrating an example of the important word file 22. The important word file 22 is a file created for each electronic book. The important word file 22 stores an important word 32 and a reference content name 33 for each page number 31.

  The page number 31 indicates the page number (page identification information) of the text content of the electronic book. The important word 32 indicates an important keyword (term) that appears on each page of the body content of the electronic book. The reference content name 33 indicates the file name (identification number) of the reference content related to the important word 32.

  In the embodiment of the present invention, before executing the content display process shown in FIG. 5, for example, the server 2 performs morphological analysis on the body content of the electronic book, and performs important analysis using a keyword extraction technique (known technique). Perform keyword extraction. Then, the server 2 sets the page number on which the extracted important keyword appears as the page number 31, the extracted important keyword as the important word 32, and the file name of the reference content associated with the important word 32 as the reference content name 33. The important word file 22 is created. The created important word file 22 is distributed to the terminal 3 together with the text content of the electronic book, and stored in the storage unit 12 of the terminal 3.

  In the example shown in FIG. 4, four important words 32 (“Oda Nobunaga”, “Takeda Shingen”, “Ashikaga Yoshiaki”, “Honnoji Temple”) are extracted for the page with page number 31 “5”. ing. Also, for “Noda Nagata”, the reference content name 33 is “odanobunaga.html”, and for “Takeda Shingen”, the reference content name 33 is “takedashingen.html”, the reference content “Yoshiaki Ashikaga” The reference content name 33 is associated with the reference content “ashikagayoshiaki.html”, and the reference content name 33 is associated with the reference content name 33 “honnoujinohen.html”.

  FIG. 5 is a flowchart for explaining the content display process. The control unit 11 of the terminal 3 executes the flowchart shown in FIG. Hereinafter, the content display process will be described with reference to FIG. 5, and FIGS. 6 to 8 will be referred to as necessary. In the flowchart shown in FIG. 5, it is assumed that the text content of the electronic book is displayed on the display unit 15 of the terminal 3.

  FIG. 6 is a diagram showing a screen display example 41 of text content. As shown in FIG. 6, the text content is displayed (highlighted) with a character decoration different from the character decoration of other characters for terms that can be browsed by the reference content. Thus, the user can easily determine which term can browse the reference content.

  In the screen display example 41 shown in FIG. 6, “Honnoji no Hen”, “Oda Nobunaga”, “Ashikaga Yoshiaki”, “Takeda Shingen” are terms that can be browsed by the reference content. These terms are lined as character decorations different from those of other characters. Of course, the character decorations of the terms that can be browsed by the reference content are not limited to the character decorations shown in FIG. For example, differences in character decorations include differences in character colors, character sizes, character fonts (Mincho, Gothic, etc.), styles (standard, italics, bold, etc.), presence or absence of sidelines, sidelines Presence / absence of presence or absence of surrounding lines is considered.

  When an instruction to start browsing the electronic book is given, the control unit 11 of the terminal 3 displays the text content on the display unit 15 as shown in FIG. 6 and waits for an input event (S1). Here, the input event is that the user performs some input via the input unit 14. When the control unit 11 of the terminal 3 detects the input event by the interrupt process, the process proceeds to the determination process of S2.

  The control unit 11 of the terminal 3 determines the content of the input event (S2). In FIG. 5, as an example, three input events (“term selection”, “page feed instruction”, “non-display of reference content”) are illustrated.

  “Term selection” means that the user designates one term that can be browsed by the reference content on the displayed page displayed on the display unit 15 via the input unit 14. When the input unit 14 and the display unit 15 are displays with a touch panel, the user performs “selection of terms” by performing an operation (tap operation) of touching a display area of terms with a fingertip or the like.

  The “page feed instruction” is that the user instructs the display of the next page on the currently displayed page displayed on the display unit 15 via the input unit 14. When the input unit 14 and the display unit 15 are displays with a touch panel, the user performs a “page feed instruction” by performing an operation (tap operation) of touching the page feed instruction area with a fingertip or the like. As shown in FIG. 6, when the text content of the electronic book is vertically written, the page turning instruction area is, for example, the lower left area of the screen. Alternatively, the user can perform “page feed instruction” by performing an operation (flick operation) of sliding the fingertip or the like while the fingertip or the like is touching the screen.

  “Reference content non-display instruction” means that when the reference content is displayed on the display unit 15, the user instructs the reference content non-display via the input unit 14. When the input unit 14 and the display unit 15 are displays with a touch panel, the user performs an operation (tap operation) of touching a reference content non-display instruction area with a fingertip or the like, thereby giving a “reference content non-display instruction”. Do. As shown in FIG. 6, when the body content of the electronic book is vertically written, the reference content non-display instruction area is, for example, a display area for terms that the reference content cannot be browsed.

  When the control unit 11 detects an input event of “term selection” (“term selection” in S2), the control unit 11 displays an important word 32 (= a term in which the reference content can be browsed) designated on the displayed page. The page number 31 of the middle page is acquired (S3). In the following, a case will be described as an example where the important word 32 designated on the displayed page is “Nobunaga Oda” and the page number 31 of the displayed page is “5”.

  Next, the control unit 11 searches the important word file 22 based on the important word 32 and the page number 31 acquired in S3, and determines the reference content to be displayed (S4). Since the important word 32 acquired in S3 is “Nobunaga Oda” and the page number 31 is “5”, the control unit 11 refers to the reference content name 33 “odanobunaga.html” from the important word file 22 shown in FIG. Specify content as a display target.

  When determining the reference content to be displayed, the control unit 11 transmits a reference content presentation request to the server 2 via the network 5. The presentation request includes identification information (“odanobunaga.html”) of reference content to be displayed. The server 2 searches the reference content stored in the reference content DB 21 based on the reference content presentation request received from the terminal 3 via the network 5 and returns the searched reference content to the terminal 3 as a search result. To do. The terminal 3 receives the reference content from the server 2 and uses it for subsequent processing.

  Next, the control part 11 searches the important word file 22 based on the page number 31 acquired in S3, and extracts an important word list (S5). However, terms related to the reference content are not included in the important word list. Since the page number 31 acquired in S3 is “5”, the control unit 11 determines that the important words 32 are “Oda Nobunaga”, “Takeda Shingen”, “Ashikaga Yoshiaki”, “Honnoji” from the important word file 22 shown in FIG. The three important words “Shingen Takeda”, “Yoshiaki Ashikaga”, and “Hennoji no Hen” are extracted as an important word list, except “Oda Nobunaga” related to the reference content.

  Next, the control unit 11 changes the character decoration of the important word included in the important word list extracted in S5 to the reference content to be displayed determined in S4, thereby changing the reference content to be displayed. The processed reference content to be displayed is displayed on the display unit 15 (S7). Examples of character decoration changes include: change of character color, change of character size, change of character font (Mincho, Gothic, etc.), change of style (standard, italic, bold, etc.), change of presence / absence of side lines, Changes in the presence or absence of neighbors, changes in the presence or absence of surrounding lines, etc. can be considered.

  FIG. 7 is a diagram illustrating an example of the reference content 42. The reference content 42 shown in FIG. 7 has the same character decoration for all characters. In S6, the control unit 11 controls the reference content 42 to include important words included in the important word list (“Shingen Takeda”, “Yoshiaki Ashikaga”, “Honnoji Temple”) “Yoshiaki Ashikaga”, “Honnoji Temple”. Change the character decoration of "weird". Thus, the user can easily determine where to browse the reference content 42. As a result, the user can immediately read the text content, and the display processing of the reference content 42 does not prevent the text content from being read.

  FIG. 8 is a diagram illustrating a screen display example 43 of the reference content 42 and the text content. The control unit 11 displays the text content and the reference content 42 in parallel as in a screen display example 43 shown in FIG. Thereby, the user can compare and browse the important word of the text content and the important word of the reference content 42.

  The control unit 11 displays the reference content 42 at least at a position that does not overlap with the designated important word 32 (“Nobunaga Oda”). Further, if possible, the control unit 11 puts the reference content 42 at a position that does not overlap with the important words 32 other than the designated important word 32 (“Shingen Takeda”, “Yoshiaki Ashikaga”, “Honnoji”). It is desirable to display.

  In the screen display example 43 of FIG. 8, “Yoshiaki Ashikaga” is surrounded by a solid line. In addition, "Honnoji no Hen" is surrounded by a dotted line. Thus, it is desirable for the control unit 11 to change to a different character decoration for each important word or for each part of speech of the important word. Thus, the user can easily determine where to browse the reference content 42 and does not overlook a portion to be browsed.

  Returning to the description of FIG. After the process of S7, the control unit 11 returns to the state waiting for an input event (S1).

  When the control unit 11 detects an input event of “page turning instruction” (“page turning instruction” in S2), if the reference content 42 is displayed, the display process of the reference content 42 is terminated ( S8), the next page is displayed (S9). As a result, the reference content 42 is not displayed on the next page, and the user does not feel bothered.

  Further, when the control unit 11 detects an input event of “non-display of reference content” (“non-display of reference content” in S2), when the reference content 42 is displayed, the display processing of the reference content 42 is performed. Is finished (S10). As a result, the user can view a part of the text content that overlaps the reference content 42.

[Effects of the embodiment of the invention]
1. The control unit 11 of the terminal 3 processes the reference content 42 by changing the character decorations of the important words included in the important word list with respect to the reference content 42, and the processed reference content 42 is displayed on the display unit 15. indicate. Thus, the user can easily determine where to browse the reference content 42. As a result, the user can immediately read the text content, and the display processing of the reference content 42 does not prevent the text content from being read.

  2. When processing the reference content 42, the control unit 11 of the terminal 3 changes to a different character decoration for each important word or for each part of speech of the important word. Thus, the user can easily determine where to browse the reference content 42 and does not overlook a portion to be browsed.

  3. The control unit 11 of the terminal 3 displays the body content and the reference content 42 in parallel as in a screen display example 43 shown in FIG. Thereby, the user can compare and browse the important word of the text content and the important word of the reference content 42.
