(Electronic book browsing process)
First, the browsing process of an electronic book is demonstrated using FIG.

  Here, the control part 21 of the management server 20 performs a user authentication process (step S101). Specifically, when the user browses the electronic book, the client terminal 10 is used to access the management server 20. In this case, the user management unit 211 of the control unit 21 of the management server 20 outputs a user authentication screen on the display of the client terminal 10. This user authentication screen is provided with user ID and password input fields. When predetermined contents are input in these input fields, the user management unit 211 acquires a user ID and password from the client terminal 10. The user management unit 211 searches the user management storage unit 23 for a user management record 230 in which the acquired user ID and password are recorded. When the user management record 230 in which the acquired user ID and password are recorded can be extracted, the user authentication is terminated. On the other hand, if the user management record 230 in which the user ID and password are recorded cannot be extracted, an error message is notified to the client terminal 10 and the provision of the service is terminated.

  Next, the control unit 21 of the management server 20 executes a book designation process (step S102). Specifically, the browsing control unit 212 of the control unit 21 outputs a book selection screen on the display of the client terminal 10. On this book selection screen, a keyword of a book to be searched can be input. The browsing control unit 212 that has acquired the keyword from the client terminal 10 extracts a book candidate in which the keyword is included in the book name or field from the electronic book storage unit 22. Next, the browsing control unit 212 outputs the book candidate to the display of the client terminal 10. Then, the browsing control unit 212 acquires the book ID of the selected book in the client terminal 10.

  Moreover, the browsing control part 212 can also output a user's browsing history to the display of the client terminal 10, and can identify a book based on this browsing history. In this case, in the distribution list storage unit 25, the search is performed from the ones with the closest browsing dates.

  Furthermore, it is possible to specify a book based on the posted review. In this embodiment, link information (URL) for accessing an electronic book to be reviewed is set in the review. This URL includes a review ID as a variable. When access using this URL is received, the book ID of the electronic book to be reviewed and the user ID of the review poster are specified based on the review ID included in the access request.

  Then, as illustrated in FIG. 8A, the browsing control unit 212 outputs the content initial screen 500 on the display of the client terminal 10. Here, when selection of the “view review” button is detected, the browsing control unit 212 extracts a review management record 240 in which the book ID of the electronic book is recorded from the review storage unit 24. Then, the browsing control unit 212 outputs the title and text of the extracted review management record 240 on the display of the client terminal 10.

  Here, when selection of the “sample browsing” button is detected, the control unit 21 of the management server 20 executes a determination process as to whether or not it is the first use (step S103). Specifically, the browsing control unit 212 of the control unit 21 determines whether or not the distribution management record 250 in which the user ID of the user and the book ID of the selected book are recorded is registered in the distribution list storage unit 25. Check. When the distribution management record 250 in which the user ID and the book ID are recorded cannot be extracted, it is determined that it is the first use.

  When it is determined to be the first use (in the case of “YES” in step S103), the control unit 21 of the management server 20 executes a determination process as to whether or not another person's review has been used (step S104). Specifically, the browsing control unit 212 of the control unit 21 confirms whether or not a variable for specifying a review is included in the access request. If the review ID cannot be extracted in the access request, it is determined that the other person's review is not used.

  When it is determined that the review of another person is not used (in the case of “NO” in step S104), the control unit 21 of the management server 20 executes a normal browsing range specifying process (step S105). Specifically, the browsing control unit 212 of the control unit 21 specifies the electronic book management record 220 in which the book ID of the electronic book desired to be browsed is recorded in the electronic book storage unit 22. Then, the browsing control unit 212 acquires the number of pages from the identified electronic book management record 220. Next, the browsing control unit 212 calculates the number of sample pages by multiplying the number of pages by a normal ratio. Next, the browsing control unit 212 generates a distribution management record 250 in which the user ID, book ID, and browsing date (current date) are recorded, and registers the distribution management record 250 in the distribution list storage unit 25. In the viewable range data area of the distribution management record 250, the calculated number of sample pages is recorded.

  On the other hand, when it is determined that another person's review is used (in the case of “YES” in step S104), the control unit 21 of the management server 20 executes the process of specifying the enlarged viewable range (step S106). ). Specifically, the browsing control unit 212 of the control unit 21 calculates the number of sample pages by multiplying the number of pages acquired from the electronic book management record 220 by the enlargement ratio. Next, the browsing control unit 212 generates a distribution management record 250 that records the user ID, book ID, browsing date (current date), and the calculated number of sample pages, and registers the distribution management record 250 in the distribution list storage unit 25. Further, the browsing control unit 212 extracts the review management record 240 in which the review ID is recorded from the review storage unit 24. Next, the browsing control unit 212 confirms whether or not the user ID of the viewer is recorded in the viewer data area of the review management record 240. If the user ID is not yet recorded, the browsing control unit 212 newly records the user ID. On the other hand, if the user ID has already been recorded, the additional user ID recording process is skipped.

  Further, when it is determined that the use is not the first time (in the case of “NO” in step S103), the control unit 21 of the management server 20 executes the browsing range specifying process in the distribution list (step S107). Specifically, the browsing control unit 212 of the control unit 21 extracts the distribution management record 250 in which the user ID and the book ID of the electronic book desired to be browsed are recorded from the distribution list storage unit 25. Then, the browsing control unit 212 acquires the number of browseable pages recorded in the browseable range data area of the distribution management record 250. Further, the browsing control unit 212 records the current date and time in the browsing date and time data area of the distribution management record 250.

  Next, the control unit 21 of the management server 20 executes a sample page providing process (step S108). Specifically, the browsing control unit 212 of the control unit 21 provides the client terminal 10 with a sample page of an electronic book that allows browsing the number of pages specified in steps S105 to S107.

  And as shown in FIG.8 (b), the client terminal 10 outputs the content display screen 510 using a book viewer. On the content display screen 510, a sample page acquired from the management server 20 is displayed.

  When it is detected that the last page that can be browsed has been reached, the control unit 21 of the management server 20 executes a determination process as to whether or not it is a review post (step S109). Specifically, the browsing control unit 212 of the control unit 21 specifies a page displayed on the display of the client terminal 10. When it is detected that the last sample page has been reached, a sample page end screen 520 shown in FIG. 8C is output. When the selection of the “write review” button is detected, the browsing control unit 212 determines that the review has been posted. Note that also when the selection of the “write review” button on the content initial screen 500 is detected, the browsing control unit 212 determines that a review has been posted.

  When it determines with review contribution (in the case of "YES" in step S109), the control part 21 of the management server 20 performs a review registration process (step S110). Specifically, the browsing control unit 212 of the control unit 21 instructs the review management unit 213 to perform review registration including the browser user ID and book ID. The review management unit 213 outputs a review registration screen 530 shown in FIG. 8D on the display of the client terminal 10. The review registration screen 530 includes input fields for title and text. When submitting a review to the SNS, the check box for SNS cooperation is selected. When the “review registration” button is selected, the review management unit 213 acquires from the client terminal 10 data related to review (title and text) and necessity of SNS cooperation. Then, the review management unit 213 generates a review management record 240 to which a review ID is assigned and registers it in the review storage unit 24. In the review management record 240, the user ID of the poster, the book ID, the posting date (current date), the title, and the text are recorded.

  Next, the control part 21 of the management server 20 performs an SNS cooperation process (step S111). Specifically, the review management unit 213 of the control unit 21 confirms whether or not the “Post to SNS” button is selected on the review registration screen. When the SNS cooperation is selected, the review management unit 213 acquires the SNS account used by the user from the user management storage unit 23. And the review management part 213 transmits a contribution message to a SNS server (social network service system). This post message includes a review (title and text) acquired from the client terminal 10. Further, the posted message includes link information (URL) for accessing the electronic book. A review ID is added to this URL as a variable. In the SNS server, the received title and text are published as a posted message in the account.

  Next, the control unit 21 of the management server 20 executes a browsing range expansion process (step S112). Specifically, the review management unit 213 of the control unit 21 calculates the number of sample pages by multiplying the number of pages recorded in the electronic book storage unit 22 by the posted enlargement ratio. Then, the review management unit 213 adds the number of pages to the viewable range (last page) of the distribution management record 250 recorded in the distribution list storage unit 25.

  When it is determined that there is no review posting (in the case of “NO” in step S109), the control unit 21 of the management server 20 skips the review registration process (step S110) and the subsequent steps, and ends the electronic book browsing process. To do.

(Preferential management processing)
Next, the preferential management process will be described with reference to FIG. This process is performed when content is browsed using a review. In this case, the review ID is acquired from the URL used in the access request.

  First, the control unit 21 of the management server 20 executes a determination process as to whether or not the content is purchased (step S201). Specifically, when the user who has read the review selects the “Purchase” button on the content initial screen 500, the preferential management unit 214 of the control unit 21 determines to purchase the content.

  Next, when it determines with content purchase (in the case of "YES" in step S201), the control part 21 of the management server 20 performs the review poster specific process (step S202). Specifically, the preferential management unit 214 of the control unit 21 extracts the review management record 240 in which the review ID included in the URL is recorded from the review storage unit 24. Then, the preferential management unit 214 identifies the review contributor by extracting the user ID recorded in the review management record 240.

  Next, the control part 21 of the management server 20 performs the expansion process of the browsing range of a review contributor (step S203). Specifically, the preferential management unit 214 of the control unit 21 specifies the electronic book management record 220 in which the book ID of the electronic book desired to be browsed is recorded from the electronic book storage unit 22. Then, the preferential management unit 214 acquires the number of pages from the specified electronic book management record 220. Next, the preferential management unit 214 calculates the number of sample pages by multiplying the number of pages by the preferential ratio. Next, the preferential management unit 214 searches the distribution management record 250 in which the user ID and book ID of the review poster are recorded. Then, the preferential management unit 214 adds the calculated number of sample pages to the viewable range (last page).

  On the other hand, when it is determined that the content has not been purchased (in the case of “NO” in step S201), the control unit 21 of the management server 20 executes a process for calculating the number of reviews viewed (step S204). Specifically, the preferential management unit 214 of the control unit 21 calculates the total number of viewers by counting the user IDs recorded in the viewer data area of the review management record 240 of the review used for access.

  Next, the control unit 21 of the management server 20 executes a determination process as to whether or not the total number of browsing is greater than the reference number of browsing (step S205). Specifically, the preferential management unit 214 of the control unit 21 compares the calculated total number of browsing and the reference number of browsing.

  Here, when it is determined that the total number of browsing is greater than the reference number of browsing (in the case of “YES” in step S205), the control unit 21 of the management server 20 executes an enlargement range specifying process (step S206). Specifically, the preferential management unit 214 of the control unit 21 specifies the electronic book management record 220 in which the book ID of the electronic book desired to be browsed is recorded from the electronic book storage unit 22, and from the electronic book management record 220 Get the number of pages. Next, the preferential management unit 214 calculates the number of sample pages by multiplying the number of pages by the preferential ratio.

  Next, the control part 21 of the management server 20 performs the expansion process of the browsing range of a review contributor (step S207). Specifically, the preferential management unit 214 of the control unit 21 searches the distribution management record 250 in which the user ID and book ID of the review poster are recorded. Then, the preferential management unit 214 adds the calculated number of sample pages to the viewable range (last page) of the extracted distribution management record 250.

  Next, the control part 21 of the management server 20 performs the notification process to a review contributor (step S208). Specifically, the preferential management unit 214 of the control unit 21 extracts the user management record 230 of the review poster from the user management storage unit 23, and acquires the contact information recorded in the user management record 230. Then, the preferential management unit 214 transmits a message indicating that the viewable range has been expanded to this contact address.

  When it is determined that the total number of browsing is equal to or less than the reference number of browsing (in the case of “NO” in step S205), the control unit 21 of the management server 20 skips the processing for specifying the expansion range (step S206) and the subsequent steps and preferential The management process ends.

According to this embodiment, the following effects can be obtained.
(1) In this embodiment, when it is determined that another person's review is used (in the case of “YES” in step S104), the control unit 21 of the management server 20 specifies the expanded viewable range. Processing is executed (step S106). Thereby, utilization of a content can be promoted using a review.

  (2) In this embodiment, when it determines with review contribution (in the case of "YES" in step S109), the control part 21 of the management server 20 performs a review registration process (step S110). The control unit 21 of the management server 20 executes a browsing range expansion process (step S112). Thereby, promotion of a review contribution can be aimed at.

  (3) In this embodiment, the control part 21 of the management server 20 performs an SNS cooperation process (step S111). Thereby, a social network service is used and a review can be expanded to a related person, and the use promotion of an electronic book through a review can be aimed at.

Thereby, the feedback with respect to a review contributor can be aimed at and review contribution can be promoted.

  (5) In the present embodiment, the control unit 21 of the management server 20 executes a process for calculating the number of reviews viewed (step S204). When it is determined that the total number of browsing is larger than the reference number of browsing (in the case of “YES” in step S205), the control unit 21 of the management server 20 executes an enlargement range specifying process (step S206). Thereby, the feedback with respect to a review contributor can be aimed at and review contribution can be promoted.

In addition, you may change each said embodiment as follows.
In the above embodiment, it is assumed that an electronic book is provided to the user as content, but the content is not limited to this. For example, the present invention can be applied to music and games. In the case of music, the usable range is expanded by lengthening the performance time. In the case of a game, the available range is expanded by increasing the number of scenes and stages where the game is possible.

  In the above embodiment, when it is determined that the content is purchased or when it is determined that the total number of browsing is greater than the reference number of browsing, the control unit 21 of the management server 20 executes the process of expanding the browsing range of the review poster (step S203, S207). Here, the viewing range is expanded using a preferential rate set in advance. The method for enlarging the viewing range is not limited to this. For example, it is possible to determine the expansion range based on the situation (the number of other reviews, the posting order, etc.) at the time of review posting by the contributor. In this case, the preferential management unit 214 holds a preferential ratio table in which preferential ratios are set corresponding to the review posting order. In this preferential ratio table, a higher preferential ratio is set when the posting order is earlier.

The enlargement range specifying process will be described with reference to FIG.
First, the control unit 21 of the management server 20 executes a process for specifying the number of reviews at the time of review posting (step S301). Specifically, the preferential management unit 214 of the control unit 21 acquires a review management record 240 for the used review from the review storage unit 24. Next, the preferential management unit 214 identifies the posting date and time recorded in the review management record 240. Then, the preferential management unit 214 counts the number of records in the review management record 240 in which the same book ID is recorded, in which the posting date and time earlier than the specified posting date and time is recorded. Is calculated.

  Next, the control unit 21 of the management server 20 executes an enlargement rate determination process according to the number of reviews (step S302). Specifically, the preferential management unit 214 of the control unit 21 specifies a preferential ratio corresponding to the number of reviews (posting order) that has already been registered in the preferential ratio table.

  Next, the control unit 21 of the management server 20 executes an enlargement range calculation process (step S303). Specifically, the preferential management unit 214 of the control unit 21 calculates the number of pages for expanding the viewable range by multiplying the number of pages of the electronic book by the specified preferential ratio.

Thereby, since the one where review contribution is early can receive many preferential treatment, review contribution can be promoted.
・ In addition, as a method of expanding the viewing range, it is possible to determine the expanded range based on the evaluation of reviews by a third party. In this case, the preferential management unit 214 holds a preferential rate table in which preferential rates are set in correspondence with the statistical values of the evaluation values of the reviews. In this preferential ratio table, a higher preferential ratio is set for a higher evaluation. Further, an evaluation value for the review is acquired from the review viewer and registered in the review storage unit 24.

The enlargement range specifying process will be described with reference to FIG.
First, the control unit 21 of the management server 20 executes past review identification processing for review posters (step S401). Specifically, the preferential management unit 214 of the control unit 21 acquires the review management record 240 for the review used by the viewer from the review storage unit 24. The preferential management unit 214 identifies the user ID recorded in the contributor data area of the review management record 240. Then, the preferential management unit 214 acquires all the review management records 240 in which the user ID is recorded from the review storage unit 24.

  Next, the control unit 21 of the management server 20 executes a review evaluation specifying process (step S402). Specifically, the preferential management unit 214 of the control unit 21 acquires evaluations recorded in all the review management records 240 acquired from the review storage unit 24, and calculates a statistical value of this evaluation. For example, an average value is used as the statistical value, but the statistical value is not limited thereto.

  Next, the control unit 21 of the management server 20 executes enlargement rate determination processing according to the review evaluation (step S403). Specifically, the preferential management unit 214 of the control unit 21 acquires the preferential ratio corresponding to the calculated statistical value from the preferential ratio table.

  Next, the control unit 21 of the management server 20 executes an enlargement range calculation process (step S404). Specifically, the preferential management unit 214 of the control unit 21 calculates the number of pages for expanding the viewable range by multiplying the number of pages of the electronic book by the specified preferential ratio.

As a result, more preferential treatment can be received for reviews with high evaluations, so that review postings that are helpful to others can be promoted.
In addition, as an expansion method of the browsing range, the expansion range can be determined based on the number of user parties (for example, followers and friends) in the SNS. In this case, the preferential management unit 214 holds a preferential ratio table in which preferential ratios are set in correspondence with the number of users. In this preferential rate table, a higher preferential rate is set for a larger number of users.

The enlargement range specifying process will be described with reference to FIG.
First, the control part 21 of the management server 20 performs the identification process of the number of user related persons of a review contributor (step S501). Specifically, the preferential management unit 214 of the control unit 21 acquires the SNS information of the review poster from the user management storage unit 23. Then, the preferential management unit 214 acquires the number of users related to this review poster account from the SNS server.

  Next, the control unit 21 of the management server 20 executes an enlargement ratio determination process according to the number of user parties (step S502). Specifically, the preferential management unit 214 of the control unit 21 specifies the preferential ratio corresponding to the number of user-related persons in the preferential ratio table.

  Next, the control unit 21 of the management server 20 executes an enlargement range calculation process (step S503). Specifically, the preferential management unit 214 of the control unit 21 calculates the number of pages for expanding the viewable range by multiplying the number of pages of the electronic book by the specified preferential ratio.

Thereby, many preferential treatment can be provided to a review contributor who has a large number of user-related persons and has many connections with a third party, thereby promoting review posting.
In addition, as a method for expanding the browsing range, the browsing range may be expanded by section delimitation in content configured by a plurality of sections. In this case, the end position (end page) of each section included in the electronic book is recorded in the electronic book management record 220. Further, the preferential management unit 214 holds data related to the number of allowable pages for determining whether the allowable range is up to the next break.

The enlargement range specifying process will be described with reference to FIG.
First, the control unit 21 of the management server 20 executes an enlargement range calculation process (step S601). Specifically, the preferential management unit 214 of the control unit 21 calculates the number of pages for expanding the viewable range by multiplying the preferential ratio held by the number of pages of the electronic book. Then, the preferential management unit 214 adds the calculated number of pages to calculate the last page in the viewable range.

  Next, the control unit 21 of the management server 20 executes a section break specifying process (step S602). Specifically, the preferential management unit 214 of the control unit 21 specifies the end page of the next section break with respect to the calculated number of pages in the viewable range (last page).

  Next, the control unit 21 of the management server 20 executes a determination process as to whether or not the next section break is within an allowable range (step S603). Specifically, the preferential management unit 214 of the control unit 21 calculates the number of remaining pages from the viewable range (last page) to the next break. When the remaining page number is equal to or smaller than the allowable page number, it is determined as the allowable range.

  When it is determined that the allowable range is reached until the next break (in the case of “YES” in step S603), the control unit 21 of the management server 20 executes the enlargement process to the page at the end of the next section break (step S604). . Specifically, the preferential management unit 214 of the control unit 21 specifies the last page of the next section break as a viewable range and registers it in the distribution management record 250.

  If it is determined that the next section break is outside the allowable range (“NO” in step S603), the control unit 21 of the management server 20 skips step S604 and ends the expansion range specifying process. . In this case, the enlargement range calculated in step S601 is used.

Thereby, since the user can browse to a place with good separation, the convenience of the user can be improved.
-Also, as a method for enlarging the viewing range, multiply the preferential rate to calculate the enlarged page. Here, when all the pages of the electronic book can be browsed, sample pages of other electronic books may be provided.

Next, the enlargement range specifying process will be described with reference to FIG.
First, the control unit 21 of the management server 20 executes an enlargement range calculation process (step S701). Specifically, the preferential management unit 214 of the control unit 21 calculates the number of pages for expanding the viewable range by multiplying the preferential ratio held by the number of pages of the electronic book. Then, the preferential management unit 214 adds the calculated number of pages to calculate the last page in the viewable range.

  Next, the control part 21 of the management server 20 performs the determination process about whether all the pages can be browsed (step S702). Specifically, the preferential management unit 214 of the control unit 21 can browse all pages when the calculated number of pages exceeds the number of pages recorded in the electronic book management record 220 of the electronic book. judge.

  When it is determined that all pages can be browsed (in the case of “YES” in step S702), the control unit 21 of the management server 20 performs a process of selecting other recommended books according to the browsing history (step S703). Specifically, the preferential management unit 214 of the control unit 21 acquires the distribution management record 250 of the reviewer from the distribution list storage unit 25. Next, the preferential management unit 214 uses the book ID recorded in the distribution management record 250 to identify the field to which the electronic book that is frequently viewed belongs. Then, the preferential management unit 214 extracts, from the electronic book storage unit 22, electronic books that belong to this field and for which the reviewer distribution management record 250 is not registered. Next, the preferential management unit 214 notifies the reviewer's client terminal 10 including an electronic book expansion candidate list.

  Next, the control unit 21 of the management server 20 performs an enlargement range calculation process on the recommended book (step S704). Specifically, when the preferential management unit 214 of the control unit 21 acquires a book ID of an electronic book for which the sample page is desired to be expanded from the client terminal 10, the distribution management record 250 in which the user ID and the book ID are recorded. Create a new one. Then, the preferential management unit 214 records the number of pages in which the viewable range is expanded in the distribution management record 250.

  If it is determined that all pages cannot be browsed (in the case of “NO” in step S702), the control unit 21 of the management server 20 skips the other recommended book selection processing (step S703) and the subsequent steps and expands. The range specifying process ends.

Thereby, not only the electronic book in which the review is posted but also other electronic books can be browsed.
In addition, as a method for enlarging the browsing range, the user may be able to select a section desired to be browsed. In addition, the preferential ratio may be changed in the selected section. In this case, a weight value is recorded for each section in the electronic book management record 220 of the electronic book storage unit 22. Here, for articles with high value, the weighting value is set high.

The enlargement range specifying process will be described with reference to FIG.
First, the control unit 21 of the management server 20 executes section display processing (step S801). Specifically, the preferential management unit 214 of the control unit 21 outputs information on the session of the electronic book to the display of the client terminal 10. If there is a section desired by the user, this section is designated. In this case, the client terminal 10 transmits a section specification request to the management server 20.

  Next, the control unit 21 of the management server 20 executes a determination process as to whether or not there is a section designation (step S802). Specifically, the preferential management unit 214 of the control unit 21 determines that there is a section designation when a section designation request is received from the client terminal 10.

  Here, when it is determined that there is no section designation (in the case of “NO” in step S802), the control unit 21 of the management server 20 executes the enlargement range specifying process in order from the front (step S803). Specifically, the preferential management unit 214 of the control unit 21 calculates the number of pages for expanding the viewable range by multiplying the preferential ratio held by the number of pages of the electronic book. Then, the preferential management unit 214 adds the calculated number of pages, and updates and records the last page in the viewable range.

  On the other hand, when it is determined that there is a section designation (in the case of “YES” in step S802), the control unit 21 of the management server 20 executes a process for specifying the weight value of the designated section (step S804). Specifically, the preferential management unit 214 of the control unit 21 acquires a weighting value for the designated section from the electronic book management record 220.

  Next, the control unit 21 of the management server 20 performs an enlargement range calculation process according to the weighting value (step S805). Specifically, the preferential management unit 214 of the control unit 21 calculates a correction ratio in consideration of the weighting by dividing the preferential ratio held by the weighting value. The preferential management unit 214 calculates the number of pages for expanding the viewable range by multiplying the number of pages of the electronic book by the correction ratio held. Then, the preferential management unit 214 records the designated section and the calculated number of pages in the viewable range data area.

  As a result, the contents of a section desired by the user can be provided in a document composed of a plurality of sections such as a magazine. Further, by weighting by section, the sample page can be expanded in consideration of the contents of each section.
