That is, the service server 100 releases the obscured state of at least one part-by-part book data purchased by the user through payment, or converts it into a file in a format in which all parts can be identified, and the payment is completed for at least one part-by-part. Book data can be provided.

Meanwhile, the service server 100 may display a list of book data for each part purchased by the user. In addition, a new e-book file including at least one book data for each part may be generated based on the user's selection of the displayed purchase list. Here, the new e-book file may be generated by sequentially arranging book data for each part included in the purchase list according to an order selected by the user.

In addition, the service server 100 may transmit the generated e-book file to the customer terminal 120 when a function to output or download the generated e-book file is selected by the user (S208).

On the other hand, as described above, the book providing server 110 or the service server 100 of the e-book sales system according to an embodiment of the present invention converts a portion of an e-book according to each table of contents of the e-book to a book by part. It has been mentioned that data can be provided. To this end, the book provider server 110 or the service server 100 identifies each paragraph of the electronic book, that is, by matching the identified paragraph with the table of contents item, paragraphs corresponding to each item in the table of contents are detected. can do. Also, based on the detected paragraph information for each item, book data for each part corresponding to the item requested by the user may be generated.

FIG. 3 is a flowchart illustrating an operation process in which the book provider server 110 or the service server 100 generates book data for each item and part according to the table of contents of the electronic book.

First, the book provider server 110 or the service server 100 detects the table of contents of book data (raw book data) including the entire contents of the e-book, and from the detected table of contents, each item included in the table of contents can be extracted (S300). In addition, the extracted items may be hierarchized according to the hierarchical relationship according to the tree structure of the table of contents. In addition, for each of the hierarchical items, relation information such as a degree, a level, and a depth of a tree may be obtained.

Here, 'order' refers to the number of sub-trees or the number of branches for one item, and may mean the number of sub-items included in one item. In addition, the 'depth of the tree' may mean the length of a path from the root item to a specific item, and the 'level' may refer to items in the same hierarchy among items according to the tree hierarchy, that is, the depth (depth). ) may mean the same nodes. Accordingly, for each item, information on a parent item and a child item, and information on an ancestor item and a descendant item may be analyzed.

Meanwhile, the book provider server 110 or the service server 100 may classify each paragraph of the raw book data and provide identification information for each divided paragraph ( S304 ).

In addition, the book provider server 110 or the service server 100 may detect the position of each item in the table of contents from the raw book data based on each identified paragraph. For example, the book provider server 110 or the service server 100 may detect paragraphs corresponding to the item detected in step S300 from among the identified paragraphs. Or, a position on a paragraph in which the same text as the name of the item is satisfied (eg, between paragraph numbers [0053] and [00554], which satisfies the conditions for displaying items preset in the raw book data, for example, font size or upper and lower margins. ) can be detected.

Then, based on the item positions on the detected paragraph, paragraphs corresponding to each item may be identified and matched for each item ( S306 ).

As an example, the book provider server 110 or the service server 100 identifies each paragraph located between any one item (first item) and the next item (second item) as paragraphs corresponding to the first item. can be identified as In addition, identification information of the identified paragraphs may be matched to the first item. Accordingly, identification information of paragraphs corresponding to the first item may be detected.

On the other hand, when identification information of paragraphs included in each item is detected, the book provider server 110 or the service server 100 determines the identification information of paragraphs for each item based on a hierarchical relationship according to the table of contents tree structure of the e-book. They can be grouped (S308). That is, the paragraph identification information may be grouped so that a higher-order item includes paragraphs corresponding to a lower-order item based on the hierarchical relationship of the table of contents. In this case, the identification information may be grouped so that the upper item includes both paragraphs corresponding to the item and paragraphs corresponding to the lower item.

As described above, through grouping of paragraph identification information according to the hierarchical structure of the table of contents, the book providing server 110 or the service server 100 may detect paragraphs of each item according to the table of contents of the e-book. In addition, when there is a request for book data for each part corresponding to the specific item, paragraphs of the raw book data corresponding to the specific item may be extracted based on the identification information group corresponding to the specific item. That is, paragraphs included only in the specific item and paragraphs corresponding to sub-items of the specific item may be extracted, and the extracted paragraphs may be provided as book data for each part of the specific item.

Meanwhile, the book data for each part may be provided through any one of the book providing server 110 and the service server 100 . In addition, the service and configuration provided by the service server 100 and the book provider server 110 may be different depending on which server of the book provider server 110 and the service server 100 provides book data for each part.

Hereinafter, an electronic book sales system according to an embodiment of the present invention according to a subject providing the book data for each part will be described in detail with reference to FIGS. 4A to 6B . In the following description, the process of the user accessing the service server 100 and searching for a specific e-book through the customer terminal 120, such as advertisement and posting on the affiliated portal site 130 (step S200 in FIG. 2 to It is assumed that the process leading to step S202) is commonly applied to all of the following embodiments. That is, each of the following embodiments may describe a process after a user accesses the service server 100 , searches for a specific e-book, and requests information on the specific e-book from the service server 100 .

First, FIG. 4A is a block diagram illustrating the configuration of an electronic book sales system according to a first embodiment of the present invention when the book provider server 110 provides book data for each part, and FIG. 4B is the first embodiment of the present invention. It is a flowchart illustrating an operation process of providing a sales service for book data for each part through the e-book sales system according to an embodiment.

As described above, the book providing server 110 according to the first embodiment of the present invention may provide book data for each part of the electronic book to the service server 100 . To this end, the book provider server 110 may generate book data for each part with respect to the raw book data of the specific e-book, and store the generated book data for each part in the storage unit 112 . Also, based on the data stored in the storage unit 112 , book data for each part according to the request of the service server 100 may be provided to the service server 100 .

As an example, the book provider server 110 may perform grouping of paragraph identification information according to the hierarchical structure of the table of contents of the specific electronic book through the process shown in FIG. 3 , and each item in the table of contents as a result of performing the identification information grouping Paragraphs corresponding to can be identified. In this case, information on paragraph identification information grouped according to the table of contents hierarchical structure may be stored in the storage unit 112 .

Alternatively, the book provider server 110 may divide the raw book data for each page of the specific e-book. In addition, the divided book data may be generated as book data for each part corresponding to each page. In addition, the generated book data for each part may be stored in the storage unit 112 of the book providing server 110 .

In this way, in the state that information for providing book data for each part, that is, information of paragraph identification information grouped according to the table of contents hierarchy or book data for each part (book data divided into pages) is stored in the storage unit 112 , the book provider The server 110 may provide book summary information of the available electronic books to the service server 100 ( S400 ). Then, the book summary information provided by the book provider server 110 is provided to the customer terminal 120 connected to the service server 100 through the service server 100 and on the display unit of the customer terminal 120 . may be displayed (S402).

Then, the user may select any one book based on the book summary information displayed through the customer terminal 120 . For example, the user may input search information and select any one of the electronic books displayed as a search result. Alternatively, any one of e-books of a specific category displayed on the customer terminal 120 may be selected. Then, detailed information about the specific e-book selected by the user may be requested from the service server 100 (S404).

Meanwhile, in response to the detailed information request, the service server 100 may provide detailed related information extracted from the book summary information of a specific e-book to the customer terminal (S406). For example, the detailed related information may include bibliographic information such as a summary of the e-book, a representative illustration, or a publisher and author of the e-book, and the time of publication. In addition, the detailed related information may include item information extracted from the table of contents of the specific e-book. In this case, the name of each item constituting the table of contents and information on pages or paragraphs corresponding to each item may be provided to the customer terminal 120 .

Meanwhile, when detailed related information on a specific e-book is provided as described above, a search request for the specific e-book may be transmitted from the customer terminal 120 to the service server 100 (S408). Here, the search request may be a search request for a specific item or a specific page of the specific e-book. For example, when the user selects any one of the item information of the table of contents, the customer terminal 120 may request information on the selected item from the service server 100 . Alternatively, when the user selects a specific page of the specific electronic book, the customer terminal 120 may request information on the selected page from the service server 100 .

Meanwhile, the service server 100 that has received the search request may transmit the received search request to the book provider server 110 (S410). Then, in response to the search request received from the service server 100 , the book provider server 110 may extract book data for each part corresponding to the search request ( S412 ). For example, when the search request is for a specific page, the book provider server 110 may extract search data for each part corresponding to the page requested in step S412 from the storage unit 112 . In addition, the extracted search data for each part may be provided to the service server 100 in response to the search request in step S410 (S414).

Alternatively, if the search request is for a specific item, the book provider server 110 is based on the paragraph identification information group corresponding to the requested item in step S412, corresponding to the requested item and a sub-item of the requested item. Paragraphs may be extracted as book data for each part from the raw book data of the specific e-book. And the extracted book data for each part may be provided in response to the search request (step S410) of the service server 100 (S414).

Meanwhile, the search request transmitted from the customer terminal 120 to the service server 100 in step S408 may be a search request for a specific search keyword. In this case, the service server 100 may transmit search request information including the search keyword to the book provider server 110 in step S410 . Then, the book provider server 110 may perform a search for the search keyword with respect to the raw book data of the specific e-book in step S412.

In addition, as a result of the search, at least one page including the search keyword may be detected based on identification information of paragraphs including the search keyword. In addition, at least one part-specific book data corresponding to at least one detected page may be extracted from the storage unit 112 . In addition, the book provider server 110 may transmit the extracted at least one book data to the service server 100 as a search result for the search keyword in step S414 .

Meanwhile, the book provider server 110 may detect, from the raw book data, at least one preset level item including the search keyword. In addition, based on the at least one paragraph identification information group corresponding to the detected item, the requested item and at least one paragraph corresponding to a sub-item of the requested item may be extracted from the raw book data of the specific e-book. In addition, the book provider server 110 may proceed to step S414 to provide the extracted paragraphs to the service server 100 as book data for each part searched according to the search keyword.

Meanwhile, the item of the preset level may be an item of the lowest level in a hierarchical structure of items according to the table of contents of the specific e-book. In this case, the book provider server 110 may transmit information about another related paragraph, that is, an ancestor-level paragraph or a parent-level paragraph (hereinafter, paragraph structure information) together with the found paragraph. And when the user further selects another paragraph through the paragraph structure information, the service server 100 proceeds to step S410 again to request book data for each part of the selected paragraph from the book provider server 110, and the book provider The server 110 may further provide the book data for each part corresponding to the requested paragraph to the service server 100 in response to the request by performing steps S412 and S414 again.

Meanwhile, the service server 100 that has received at least one book data for each part from the book provider server 110 in response to the search request in step S410 may perform a masking process on the received book data for each part. (S416). For example, the service server 100 displays only a portion of the received book data for each part so that it can be identified, and distorts or blurs the rest so that it is difficult to identify, or a graphic in which the remaining part except for the identifiable part is preset. You can perform image processing that is obscured by an object.

Here, the identifiable part may be text information corresponding to a preset number of lines (eg, one line) or text information corresponding to a preset number of words. Alternatively, when the search request is a search request for a search keyword, the identifiable part may be the search keyword and text information around the search keyword. For example, it may be text information corresponding to words before and after the search keyword or one line including the search keyword.

Meanwhile, step S416 may be a step in which the service server 100 converts the received book data for each part into a preset file format. For example, in step S416, the service server 100 may be a step of converting the received book data for each part into image data having a preset resolution. In this case, the converted image data may be generated as book data for each limited portion.

If, through the masking process of step S416, limited portion-specific book data is generated and the rest are not identified, the service server 100 responds to the search request received from the customer terminal 120 in step S406. As a response, it is possible to transmit the book data for each limited part (S418).

Meanwhile, the limited book data for each part may include price information for each of the book data for each part. Here, the price of the book data for each part may be determined by the book providing server 110 or the service server 100 . Preferably, the price of the book data for each part may be determined by a server that generates the book data for each part. In this case, when the book providing server 110 generates book data for each part as in the first embodiment of the present invention, the price of each book data for each part may be determined by the book providing server 110 .

For example, the price of the book data for each part may be determined based on the price (list price) of the specific e-book. In this case, the price of book data for each page may be determined as a value obtained by dividing the list price of the specific e-book by the total number of pages. In addition, the price of book data for each item is determined by dividing the list price of the specific e-book by the total number of paragraphs included in the specific e-book to determine the unit price, and multiplying the calculated unit price by the number of paragraphs included in each item. there is. In this case, as the number of included paragraphs increases, the price of book data for each item may increase.

Meanwhile, in a similar manner to this, the unit price may be determined based on the number of characters or lines of the specific e-book. In this case, the illustration or graph may be regarded as having a preset number of characters or lines.

The price of the book data for each page may be calculated by multiplying the calculated unit price by the number of characters or lines of each page. In this case, even on the same page, the price of book data for each page may vary depending on the number of characters or lines on the page.

Alternatively, the price of the book data for each item may be calculated by multiplying the calculated unit price by the number of characters or lines of the book data for each item. In this case, even if the number of paragraphs included in an item is the same, the price of book data for each paragraph may vary according to the number of characters or lines of the paragraphs.

As such, unlike the standard pricing method that determines the price based on the amount according to a preset calculation unit (eg, page, paragraph, character, line) regardless of the content of the book data for each part, the content of the book data for each part A random pricing method in which prices are set differently based on In this case, the pricing entity, that is, the book provider server 110 or the service server 100, may calculate the importance level for each paragraph or page, and set the price of book data for each item or page differently according to the calculated importance level. can decide The process of determining the price of book data for each part according to the arbitrary pricing method will be described in more detail with reference to FIG. 7 below.

Meanwhile, a user's purchase request and payment may be made with respect to at least one of the book data for each limited section provided in response to the search request of step S408 ( S420 ). Then, the service server 100 may provide the book data for each part that is not image-processed or converted with respect to at least one part-by-part book data purchased by the user (S422). Accordingly, with respect to the purchased book data for each part, the user may check the entire contents, or print or download the book.

In this case, the service server 100 may provide an editing function for the purchased book data for each part according to the user's request (S424). In this case, the service server 100 may provide an editing interface including a list (purchase list) of book data for each part purchased by the user to the customer terminal 120 . Then, the user may select at least some of the book data for each part included in the purchase list to generate the user-ordered e-book.

The user can freely change the order or location of book data for each part to be included in the user-ordered electronic book through the editing interface. For example, the user may freely change the order of book data for each part to be included in the user-ordered e-book by changing the order of selecting the book data for each part displayed on the purchase list. In this case, the book data for each part may be arranged in an order different from the table of contents item of the e-book corresponding to the book data for each part.

In addition, the user may create one user-ordered e-book including book data for each part purchased from different e-books. To this end, the editing interface may display purchase lists including book data for each part of different e-books purchased by the user on one screen, and the service server 100 may display a plurality of purchases displayed on one screen. According to an order selected by the user from the list, book data for each part of the different e-books corresponding to each purchase list may be sequentially arranged to generate the user-ordered e-book.

Meanwhile, the purchase list may include different types of book data for each part (eg, book data for each page and book data for each item). Accordingly, the user-ordered e-book may include different types of different types of book data for each part.

In addition, the editing interface provides a paragraph division function for dividing the purchased book data for each part by paragraph, or an editing window for displaying the contents of the book data for each part so that the user can extract a part of the book data for each part can provide Accordingly, the user may divide the book data for each part purchased by the user into smaller units, for example, paragraph units, and arrange the divided paragraphs in an arbitrary position or order using the editing function. Accordingly, a user-ordered e-book including only a part of the book data for each part at least one can be generated.

In addition, the service server 100 may provide the user with the user-ordered e-book generated through the editing function provided in step S424 (S426). For example, the service server 100 may transmit the user-ordered e-book generated through the editing function to the customer terminal 120 in step S426 .

On the other hand, in the first embodiment of the present invention described above, the book providing server 110 according to the search request of the service server 100, a portion of the specific e-book corresponding to the search result in the form of book data by the service server An example given in (100) has been described. However, unlike this, the book provider server 110 may provide the entire book data for each part generated from the specific e-book to the service server 100 in response to the request of the service server 100 for the specific e-book. Of course.

5A and 5B are, as described above, an electronic book sales system according to the second embodiment of the present invention that provides the entire book data for each part of a specific e-book to the service server 100 in response to a request from the service server 100. A block diagram and a flowchart showing the configuration of

Referring to FIGS. 5A and 5B , the book providing server 110 according to the second embodiment of the present invention may provide book data for each part of the electronic book to the service server 100 . To this end, the book provider server 110 may generate book data for each part with respect to the raw book data of the specific e-book, and store the generated book data for each part in the storage unit 112 .

Here, the book data for each part may be information on paragraph identification information grouped through the paragraph identification information grouping process illustrated in FIG. 3 and book data for each paragraph obtained by dividing the raw book data of the specific e-book into paragraphs. Alternatively, it may be page-by-page book data obtained by dividing the raw book data of the specific e-book for each page of the specific e-book. In addition, the book providing server 110 may store the book data for each part in units of e-books.

In this way, in a state where information for providing book data for each part, information of grouped paragraph identification information, or book data for each page is stored in the storage unit 112 , the book provider server 110 provides book summary information of available electronic books These may be provided to the service server 100 (S500). Then, the book summary information provided by the book provider server 110 is provided to the customer terminal 120 connected to the service server 100 through the service server 100 and on the display unit of the customer terminal 120 . may be displayed (S502).

Meanwhile, the user may select any one book based on the book summary information displayed through the customer terminal 120 . Then, a specific e-book selected by the user may be requested from the service server 100 (S504). In addition, the service server 100 may request the book data for each part for a specific electronic book requested by the user from the book provider server 110 (S506).

Then, the book provider server 110 may search the book data for each part stored in the storage unit 112 for each e-book in units of e-books. In addition, book data for each part corresponding to the requested electronic book may be searched from the search result service server 100 . In response to the specific e-book request, the searched book data for each part may be provided to the service server 100 (S508).

Here, the book provider server 110 may search and transmit the book data for each part in an e-book unit, and accordingly, the book data for each part provided to the service server 100 in step S508 is the entire requested specific e-book. It may be book data for each part. That is, in the step S508, the book provider server 110 is grouped with respect to a file in which book data for each page of the specific e-book is compressed or book data for each paragraph and items according to the table of contents of the specific e-book. A compressed file of paragraph identification information may be transmitted to the service server 100 . In addition, book data for each part of the entire specific e-book transmitted to the service server 100 may be stored in the storage unit 104 of the service server 100 .

Meanwhile, in step S504, in response to the user's request for the specific e-book, the service server 100 may provide detailed related information extracted from the book summary information of the specific e-book to the customer terminal.

In response to the provided detailed related information, a search request for the specific e-book may be transmitted from the customer terminal 120 to the service server 100 (S510). Here, the search request may be a search request for a specific item or a specific page of the specific e-book.

Meanwhile, the service server 100 receiving the search request may perform a search according to the search request based on the book data for each part of the entire specific e-book stored in the storage unit 104 (S512). To this end, the service server 100 may further include a search unit 102 for performing the search, and respond to the search request from the book data for each part of the entire specific e-book through the search unit 102 . It is possible to search the corresponding at least one book data for each part (S512).

For example, when the search request is for a specific page, the search unit 102 may search the book data for each part corresponding to the requested page from the storage unit 104 . Alternatively, when the search request is for a specific item, the search unit 102 may configure a paragraph corresponding to the requested item and a sub-item of the requested item based on a group of paragraph identification information corresponding to the search-requested item. Book data for each part corresponding to the books may be searched from the storage unit 104 .

Meanwhile, the search request in step S510 may be a search request for a specific search keyword. In this case, the service server 100 may perform a search for the search keyword on the book data for each part of the entire specific e-book.

For example, the service server 100 may search for at least one page including the search keyword. Alternatively, the service server 100 may search for at least one paragraph including the search keyword. In addition, information related to an item of a preset level corresponding to the searched paragraph may be detected.

Here, the item of the preset level may be the item of the lowest level among the hierarchical structure of items according to the table of contents of the specific e-book. In addition, the information related to the item may be information about another paragraph associated with the item corresponding to the found paragraph according to a hierarchical structure of the table of contents, that is, an ancestor-level paragraph or a parent-level paragraph.

In addition, the service server 100 may perform a masking process on the book data for each part searched for by the search unit 102 in step S512 (S514). In addition, at least one book data for each part restricted so that only a part can be identified through the masking process may be provided in response to the search request of the step S510 ( S516 ). Here, step S516 of performing the masking process on the book data for each part may be the same as step S416 of FIG. 4 at least in part.

Meanwhile, the service server 100 may provide price information including prices for each of the at least one limited-part book data together with the at least one limited-part book data. Here, the price information can be determined by the subject who generates and provides the book data for each section, and when the subject that generates the book data for each section is the book provider server 110 as in the second embodiment of the present invention described above , the price of book data for each part may be determined by the book provider server 110 .

Also, as described with reference to FIG. 4, the price of each book data for each part may be determined according to a standard pricing method that is uniformly calculated according to a preset calculation unit based on the price of the specific e-book. Alternatively, the price may be determined according to a random pricing method in which the price is determined differently according to the contents of each book data for each part.

As such, when price information including at least one limited book data for each part and the price of book data for each part is provided, the user purchases at least one book data for each part based on the provided price information to the service server ( 100) can be requested. And when the authentication and payment process is performed (S518), the service server 100 provides the purchased at least one book data for each part to the customer terminal 120 in a non-occluded state, that is, in an unrestricted state. It can be done (S520). In addition, according to the user's request, it is possible to provide an editing function for the purchased book data for each part (S522).

Here, the editing function provided through the service server 100 may be an editing function that is at least partially similar to the editing function described in step S424 of FIG. 4 . That is, the service server 100 may display a list of book data for each part for at least one e-book purchased by each user in step S522, and based on the user's input to the displayed list, the at least one It is possible to create a user-ordered e-book including book data for each part of the e-book. In addition, the generated user-ordered electronic book may be provided to the customer terminal 120 (S524).

Meanwhile, the first and second embodiments of the present invention described above have been described on the assumption that the book providing server 110 generates book data for each part of the e-book. However, unlike this, the book provider server 110 provides raw book data of the unprocessed electronic book to the service server 100 at the request of the service server 100, and the service server 100 receives the raw book data from the raw book data. Of course, it is also possible to extract the book data for each item or extract the book data for each page and provide it to the user. Hereinafter, an embodiment of the present invention in which the service server 100 processes the book data (hereinafter, raw book data) in the raw state transmitted from the book providing server 110 as described above to provide book data for each part, It will be described as a third embodiment of the invention.

6A is a block diagram for explaining the configuration of the electronic book sales system according to the third embodiment of the present invention. Also, FIG. 6B is a flowchart illustrating an operation process in which the service server 100 generates book data for each part and provides a sales service for the generated book data for each part to a user according to the third embodiment of the present invention. am.

Referring to FIGS. 6A and 6B , the storage unit 112 of the book provider server 110 may store raw book data for each of a plurality of e-books, that is, book data in a raw state. .

In addition, the book provider server 110 may provide book summary information for each of the electronic books stored in the storage unit 112 to the service server 100 ( S600 ). Then, the book summary information provided by the book provider server 110 may be provided to the customer terminal 120 connected to the service server 100 through the service server 100 , and the display unit of the customer terminal 120 . may be displayed on the screen (S602).

Meanwhile, the user may select any one book based on the book summary information displayed through the customer terminal 120 . Then, a specific e-book selected by the user may be requested from the service server 100 (S604). Then, the service server 100 may request the book data for the e-book (hereinafter referred to as a specific e-book) requested by the user from the book provider server 110 (S606). Then, the book provider server 110 may provide the raw book data corresponding to the specific e-book to the service server 100 in response to the request of the service server 100 (S608). In addition, the raw book data received from the book provider server 110 may be stored in the storage unit 104 of the service server 100 .

Meanwhile, the service server 100 receiving the raw book data from the book provider server 110 may receive a search request for the specific e-book from the user's customer terminal 120 (S610). Here, the search request for the specific e-book may be a search request for a specific item or a specific page of the specific e-book.

Then, the service server 100 may perform a search according to the search request for the raw book data of the specific e-book stored in the storage unit 104 (S612). To this end, the service server 100 may further include a search unit 102 for performing the search, and corresponds to a specific item or a specific page requested by the user from the raw book data through the search unit 102 . part can be searched for. Then, book data for each part corresponding to a part of the retrieved raw book data may be generated (S614).

For example, the service server 100 may search for a portion corresponding to a specific page requested by the user from the raw book data. Then, the searched part may be extracted from the raw book data, and book data for each part corresponding to the requested specific page may be generated. To this end, the service server 100 may further include an extraction unit 106 for extracting a portion corresponding to the search result from the raw book data.

Meanwhile, the service server 100 may match the identification numbers of each paragraph of the raw book data for each paragraph through the process described with reference to FIG. 3 , and group them according to the item structure of the table of contents. Accordingly, if the search request for the specific e-book in step S610 is for a specific item in the table of contents of the specific e-book, the service server 100 selects the paragraphs corresponding to the specific item requested to be searched, the grouped paragraphs It is identified through the identification information, and the identified paragraphs may be extracted from the raw book data through the extraction unit 106 . In addition, the extracted paragraphs may be generated as book data for each part corresponding to the requested item.

Meanwhile, the search request for a specific e-book in step S610 may be a search request for a specific search keyword. In this case, the service server 100 may search the raw book data for the search keyword.

In this case, the service server 100 may search for a paragraph of raw book data including the search keyword. In addition, information related to items of a preset level corresponding to each of the found at least one paragraph may be detected. Here, the item of the preset level may be an item of the lowest level among the hierarchical structure of items according to the table of contents of the specific e-book. In addition, the information related to the item may be information about another paragraph related to the item corresponding to the found paragraph according to the hierarchical structure of the table of contents, that is, an ancestor-level paragraph or a parent-level paragraph.

And the service server 100 through the extraction unit 106, paragraphs corresponding to the item of the preset level including the retrieved paragraph from the raw book data, or at least one page including the searched paragraph. A corresponding part may be extracted. In addition, the extracted part may be generated as book data for each part. Accordingly, book data for each part of an item including the search keyword or book data for each part of a page including the search keyword may be generated.

Meanwhile, it goes without saying that the service server 100 may extract only paragraphs including the search keyword from the raw book data. In this case, book data for each part may be generated for each at least one paragraph including the search keyword.

In addition, the service server 100 may perform a masking process on the book data for each part generated in step S614 (S616). In addition, at least one book data for each part restricted so that only a part can be identified through the masking process may be provided in response to the search request of the step S610 (S618). Here, step S616 of performing the masking process on the book data for each part may be the same as step S416 of FIG. 4 at least in part.

Meanwhile, the service server 100 may provide price information including prices for each of the at least one limited-part book data together with the at least one limited-part book data. And, as in the third embodiment of the present invention described above, when the subject generating book data for each part is the service server 100 , the price of book data for each part may be determined by the service server 100 .

Also, as described with reference to FIG. 4, the price of each book data for each part may be determined according to a standard pricing method that is uniformly calculated according to a preset calculation unit based on the price of the specific e-book. Alternatively, the price may be determined according to a random pricing method in which the price is determined differently according to the contents of each book data for each part.

As such, when price information including at least one limited book data for each part and the price of book data for each part is provided, the user purchases at least one book data for each part based on the provided price information to the service server ( 100) can be requested. And when the authentication and payment process is performed (S620), the service server 100 provides the purchased at least one book data for each part to the customer terminal 120 in a state in which the occlusion process is not processed, that is, in an unrestricted state. It can be done (S622). In addition, according to the user's request, it is possible to provide an editing function for the purchased book data for each part (S624).

Here, the editing function provided through the service server 100 may be an editing function that is at least partially similar to the editing function described in step S424 of FIG. 4 . That is, the service server 100 may display a list of book data for each part for at least one electronic book purchased by each user in step S624, and based on the user's input to the displayed list, the at least one It is possible to create a user-ordered e-book including book data for each part of the e-book. In addition, the generated user-ordered electronic book may be provided to the customer terminal 120 (S626).

According to the above description, it has been mentioned that the price of the book data for each part can be generated by the subject that generates the book data for each part by extracting the book data according to the item or page. Accordingly, in the case of the electronic book sales system according to the first and second embodiments of the present invention, the book providing server 110 may determine the price of book data for each part. On the other hand, in the case of the electronic book sales system according to the third embodiment of the present invention, the service server 100 may determine the price of book data for each part.

Meanwhile, the price of the book data for each part may be determined based on the price of the entire e-book, that is, the entire volume and the unit price calculated according to a preset calculation unit (eg, page, paragraph, character, line). That is, by calculating the amount per page, the amount per paragraph, or the amount per letter or line, the price of the book data for each section can be calculated according to the number of pages, paragraphs, or letters or lines of the book data for each section.

Hereinafter, regardless of the content of the book data, the method in which the price uniformly calculated based on the amount of book data for each section is determined is referred to as the standard amount determination method, and Let's call it the standard amount.

On the other hand, in the case of an e-book, a part that is closely related to the subject or has a great influence on the overall content may be more important than a part that is not. For example, in the case of a portion in which the entire contents of the e-book can be inferred due to a partial content, the user may have the same effect as reading the entire e-book by reading only the partial contents.

In this case, determining the price of the above part in the same way as other parts of the e-book may cause unreasonable damage to the provider of the e-book, for example, the book provider. Accordingly, the price of the book data for each part may be determined according to a random pricing method in which the price is determined differently according to the contents of the book data for each part.

7A and 7B are flowcharts illustrating an operation process of determining the price of book data for each part based on the importance calculated for each paragraph in order to determine the price of book data for each part in this way, It is an exemplary diagram illustrating an example of a price distribution for determining a price according to a random pricing method.

First, referring to FIG. 7A illustrating an operation process of determining the price of book data for each part, the book providing server 110 or the service server 100 is the entire book, that is, each of the e-books based on the list price of the e-book. A standard amount for a paragraph may be calculated (S700). For example, the book provider server 110 or the service server 100 may calculate the list price of the e-book and a unit amount according to a preset calculation unit. That is, when the calculation unit is 'characters', the book provider server 110 or the service server 100 detects the number of characters from the raw data of the e-book, divides the list price of the e-book by the detected number of characters, and each character It is possible to determine a uniform amount for , that is, a unit amount. In addition, for each paragraph of the e-book, the number of characters included in the paragraph may be multiplied by the unit amount to calculate a standard amount for the corresponding paragraph.

Meanwhile, even when the calculation unit is different, the standard amount for each paragraph may be calculated in a similar manner. For example, when the calculation unit is 'line', the book provider server 110 or the service server 100 detects the number of lines of the electronic book, and divides the list price of the electronic book by the detected number of lines for each line. You can determine the unit amount for In addition, the standard amount of each paragraph can be calculated based on the number of lines for each paragraph of the e-book.

Meanwhile, when the calculation unit is 'paragraph', the unit price for each paragraph may be determined by dividing the list price of the electronic book by the number of paragraphs detected from the electronic book. In this case, the unit amount for each paragraph may be the standard amount for each paragraph.

When the standard amount is calculated for each paragraph in step S700, the book provider server 110 or the service server 100 may calculate the importance level for each paragraph (S702). Here, the importance of each paragraph may be determined according to how closely each paragraph is related to the subject of the e-book. The importance of each paragraph may be predetermined by a content provider of the e-book, or may be automatically calculated according to words included in each paragraph.

For example, a paragraph including more predetermined important words may be classified as a paragraph closely related to a subject. That is, the importance of each paragraph may be calculated according to the number of times preset important words such as a specific person's name (eg, the name of a main character), a specific region, or a specific thing are included. Here, the importance weights of the important words may be set differently. In this case, the importance of each paragraph may be calculated based on the sum of weights of the important words included in each paragraph.

Meanwhile, when the importance of each paragraph is calculated in step S702, the book provider server 110 or the service server 100, the calculated importance for each paragraph and the number of paragraphs matching each importance follow a preset distribution curve. It is possible to determine the median value of (S704).

On the other hand, the distribution curve shows the distribution of the number of paragraphs for different importance values, and the median value (m) of the importance is as shown in FIG. 7B. It may be a value of specific importance to

To this end, the book provider server 110 or the service server 100 may detect factors having the same importance value, ie, the number of paragraphs, based on the values of importance calculated for each paragraph. And the importance value having the largest number of factors may be determined as the median value (m). Alternatively, the book provider server 110 or the service server 100 may obtain an average of the importance values calculated for each paragraph, and determine the importance value closest to the calculated average as the median value (m).

Meanwhile, when the median value of importance is determined in step S704, the number of paragraphs corresponding to each importance value may be detected based on the determined median value. Accordingly, as shown in FIG. 7B , the number of paragraphs corresponding to each importance value may be distributed in a form similar to a normal distribution curve around a median value.

As such, when the median value is determined so that the number of paragraphs corresponding to each importance value is distributed similarly to the normal distribution curve, the book provider server 110 or the service server 100 corresponds to each importance value based on the distribution curve. A price may be determined (S706).

In this case, the book provider server 110 or the service server 100 may determine a plurality of regions in which price increase/decrease rates are determined differently based on a median value. For example, based on the median value, in the distribution curve, an area including 50% of all paragraphs (first area), an area including 35% (second area), and an area including the remaining 15% ( third region), and the rate of increase or decrease of the price may be determined differently according to each divided region.

For example, the first area may be an area in which a price increase/decrease rate corresponds to 10%. The first area is an area in which the price increase/decrease rate corresponds to 10%. When the importance value exceeds the median value (m), it is +10%, and when the importance value is less than the median value (m), the price increase/decrease rate is -10%. can have That is, the importance values of the first region 710a that exceed the median value m have a price increase/decrease rate of +10%, and the importance values of the first region 710b that are less than the median value m have a price increase/decrease rate of -10%. can And in the same way, the importance values of the second region 720a that exceed the median value m and the importance values of the third region 730a are +20% and +30%, respectively, and the importance values of the second region 720a that exceed the median value m are +20% and +30%, respectively. The importance values of the second region 720b and the importance values of the third region 730b may have price increase/decrease rates of -20% and -30%, respectively. Here, the price increase/decrease rate of the importance value corresponding to the median value m may be 0%.

When the price increase/decrease rate for each importance is determined in this way, the book providing server 110 or the service server 100 may determine the price for each paragraph according to the price increase/decrease rate corresponding to each importance. That is, the book provider server 110 or the service server 100 may determine the price increase/decrease rate of each paragraph based on the importance of each paragraph calculated in step S702. In addition, the price for each paragraph may be determined by multiplying the determined price increase/decrease rate by the standard amount of each paragraph calculated in step S700. In this case, a paragraph with high importance may have a price that is up to 30% higher than the standard price calculated according to the standard pricing method, and a paragraph with low importance may have a price that is up to 30% lower than the standard amount.

On the other hand, as shown in FIG. 7B, the number of paragraphs for each importance value follows a normal distribution curve by the determined median value (m), and the region where the price increase/decrease rate is determined differently is formed symmetrically around the median value. In this case, the average of the overall price increase/decrease rate may be 0. That is, although the price of each paragraph is set differently according to the content of the paragraph, the total price of all paragraphs may be equal to the list price of the e-book.

On the other hand, when the price of each paragraph is determined based on the standard amount for each paragraph and the price increase/decrease rate for each paragraph, the book provider server 110 or the service server 100 determines the price of the book data for each part based on the determined price of each paragraph. A price may be determined (S708).

For example, if the book data for each part is book data for each part corresponding to one item in the table of contents, the book provider server 110 or the service server 100 may provide paragraph identification information grouped according to the item structure of the table of contents. Based on the detection of paragraphs corresponding to the one item, prices of the detected paragraphs may be summed to determine the price of book data for each part corresponding to the one item of the table of contents. Or, for example, if the book data for each part is book data for each part corresponding to a specific page, the book provider server 110 or the service server 100 may determine the specific based on paragraphs included in the specific page. It is possible to determine the price of the book data for each part corresponding to the page. In addition, information (price information) related to the determined price of the book data for each part may be provided together when the limited book data for each part provided in response to the user's search request is provided.

Meanwhile, in the case of the arbitrary pricing method in which the price is calculated according to the importance of the book data as described above, the price may be determined based on how well the paragraph included in the book data for each part requested by the user matches the subject of the e-book. Therefore, even when the same content is included, in the case of e-books having different subjects, prices for the same content may be determined differently. In this case, the user can purchase the same or similar content at a lower price by comparing the searched for a plurality of e-books and the prices for the searched book data for each part.

8 is a conceptual diagram for explaining an example in which price comparison is made for book data for each part including the same and similar content.

For example, it may be assumed that e-books (e-book A and e-book B) include content related to the environment of a specific city. In this case, the e-book A (Fig. 8(a)) and e-book B (Fig. 8(b)) are about the same surrounding environment in the same city (city t) as shown in Fig. 8 ( 810 and 820).

Meanwhile, the e-book A may be a book for mainly explaining the contents related to the city t. Accordingly, the content 810 describing the city t and its surrounding environment is closely related to the subject of the e-book A, and thus corresponds to a paragraph of relatively high importance among the paragraphs constituting the e-book A. can be Therefore, the price of the first paragraph 810 of the e-book A may be determined to be higher than that of other paragraphs, and the book data for each first part including the first paragraph 810 may have a higher price (e-book). Assume that A and e-book B have the same price).

On the other hand, e-book B may be a book to focus on the daily life of various animals and plants. In addition, the contents 810 describing the city t and its surrounding environment may be additionally added during the description of 'humans' among various animals and plants. Accordingly, the contents 820 describing the city t and the surrounding environment in the e-book B have little to do with the subject of the e-book B, and thus have relatively low importance among the paragraphs constituting the e-book B. It could be a paragraph. Therefore, the price of the second paragraph 820 of the e-book B may be determined to be lower than that of other paragraphs, and the price of the book data for each second section including the second paragraph 820 may be low (e-book). Assume that A and e-book B have the same price).

Meanwhile, as shown in FIG. 8 , through a search for a plurality of e-books, the user may search for book data for each part having different prices including the same or similar content. In this case, the user can purchase information of the same content at a lower price by purchasing the book data for each part of a lower price through price comparison.

In the above description, the configuration of e-book sales systems of the present invention that provide sales service for book data by part by extracting book data according to items or pages, and the process of performing the sales service according to each embodiment in detail saw.

In the following description, the creation of user-ordered electronic books through the service interface provided through the customer terminal 120 provided when the user accesses the service server 100 and the editing function provided through the service interface will be described in more detail. to explain

9 is a diagram illustrating an example of a service interface screen including information on an electronic book related to book data for each part purchased by a user in the electronic book sales system according to an embodiment of the present invention. And FIG. 10 is an exemplary diagram illustrating an example of displaying information on book data for each part purchased by the user on the service interface screen of FIG. 9 . 11 is a conceptual diagram for explaining an example of creating a user-ordered electronic book by editing a plurality of book data for each part purchased by a user through an editing window according to user convenience.

When the customer terminal 120 connects to the service server 100 of the electronic book sales system according to an embodiment of the present invention and performs a login, as shown in FIG. 9 , it corresponds to the book data for each part previously purchased by the user. A main screen including information of each e-book to be read may be displayed. In this case, the main screen of the e-books may include e-book summary information 900 for bibliographic information such as covers and authors, and evaluation information for the e-book, that is, a star rating 910 or text evaluation 920 ) can be inputted may be displayed adjacent to each of the e-book summary information 900 .

In this case, according to the user's selection of the evaluation information area 910 or 920, it is possible to check the evaluation information input by another user for the specific e-book selected by the user.

In addition, the main screen may include a keyword input area 930 in which a search word for searching for an e-book can be input. In this case, when a user inputs a keyword into the keyword input area 930, an electronic book matching the input keyword may be searched. Here, the searched e-book may be an e-book that the user pre-purchased through book data purchase for each part or an e-book that can be provided by the book provider server 110 .

Meanwhile, when the user selects any one of the book summary information 900 of each e-book corresponding to the previously purchased book data for each part, as shown in FIG. 10 , information 900 on the selected e-book , 910 and 920 together with the purchase list 1000 of book data for each part purchased by the user in the corresponding e-book may be displayed.

In this case, the purchase list 1000 may display book data 1002 for each part corresponding to a specific item purchased by the user and book data 1004 for each part corresponding to a specific page purchased by the user. In this case, depending on the type of book data for each part, that is, whether the purchased book data for each part is an item or a page, the book data for each part purchased may be distinguished from each other, and may be displayed differently.

For example, as shown in FIG. 10 , in the case of book data 1004 for each part corresponding to a specific page, information on the corresponding page may be further displayed. Alternatively, in the case of book data for each paragraph, a specific symbol indicating that it is a paragraph may be further displayed.

Meanwhile, as shown in FIG. 10 , the user may select and download at least some of the book data for each part that the user has purchased. For example, the user may select a check box displayed to correspond to the book data for each part, and select book data for each part corresponding to the check box. In addition, when the user selects the download 1010 , only a selected portion of the book data for each part of the purchase list 100 by the user may be transmitted to the customer terminal 120 . On the other hand, when the user selects the full download 1020 , the entire book data for each part of the purchase list may be transmitted to the customer terminal 120 .

Alternatively, when the download 1010 is selected by the user, the book data for each part selected through the check box may be displayed on the editing window 1100 displayed according to the selection of the download 1010 . In addition, they may be sequentially arranged on the editing window 1100 according to the order selected by the user.

For example, as shown in (a) of FIG. 11 , the purchase list 1000 includes book data for each part purchased from book A (book data for each first part 1101 ) and for each part purchased from book B. It may include book data (book data 1102 for each second part), and book data for each part purchased in book C (book data 1103 for each third part). In addition, the service server 100 may arrange the book data 1101 , 1102 , and 1103 for each part displayed in the purchase list 1000 on the editing window 1100 in the order selected by the user.

As an example, the user selects the book data 1101 , 1102 , and 1103 for each part displayed in the purchase list 1000 , the first part book data 1101 , the second part book data 1102 , and the third It can be selected in the order of the book data 1103 for each part. Then, as shown in (b) of FIG. 11 , the first part book data 1101 , the second part book data 1102 , and the third part book data 1101 are displayed on the editing window 1100 . They can be arranged in order. In this case, a user-ordered e-book in which the first, second, and third book data 1101, 1102, and 1103 are sequentially arranged may be generated.

Alternatively, the user may select the book data 1101, 1102, and 1103 for each part displayed in the purchase list 1000, the second part book data 1102, the first part book data 1101, and the third part It can be selected in the order of the separate book data 1103 . Then, as shown in (c) of FIG. 11 , the first part-by-part book data 1101 , the third part-specific book data 1103 , and the third part-specific book data 1103 are displayed on the editing window 1100 . They can be arranged in order. Accordingly, a user-ordered electronic book in which the book data 1102 for each second portion is arranged first, and the book data 1101 and 1103 for the first and third portions are arranged next, may be generated. And the generated user-ordered e-book may be transmitted to the customer terminal 120 according to the user's selection.

Meanwhile, in the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention.

The present invention described above can be implemented as computer-readable codes on a medium in which a program is recorded. The computer-readable medium includes all types of recording devices in which data readable by a computer system is stored. Examples of computer-readable media include Hard Disk Drive (HDD), Solid State Disk (SSD), Silicon Disk Drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. There is also a carrier wave (eg, transmission over the Internet) that is implemented in the form of.

Accordingly, the above detailed description should not be construed as restrictive in all respects but as exemplary. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are included in the scope of the present invention.
