JP5803382B2 - Advertisement distribution method in electronic book, advertisement display method, and electronic book browsing terminal - Google Patents

Description

  The present invention relates to a method of displaying an advertisement when an electronic book is browsed on a device including a display.

  As an advertisement display method in various web services, an advertisement display area is defined in a web page, and an advertisement requested from an advertisement server is generally displayed. Some ads are displayed on a web page as a fixed advertisement image or video, but by analyzing the content of the web page and displaying an advertisement that matches the content, It is common practice to distribute advertisements according to preferences. In patent document 1, after specifying the information used as an advertisement target, the content of the target web page is analyzed, the topic of the web page is extracted, the target information of the advertisement is compared with the topic of the web page, and the advertisement is distributed. A method of determining is described.

  On the other hand, in recent years, so-called electronic books for browsing magazines, novels, and the like on a display are spreading. E-books are often distributed via the Internet, and can be used on terminals with various display sizes, from stationary terminals such as conventional desktop personal computers to touch-panel portable terminals and tablet information terminals. Books are being offered.

  When advertisements are distributed to such electronic books, the following problems have occurred. That is, since the paper size is determined for a paper-based book and the display area is constant, the advertisement display position is laid out in advance, and the advertisement is always displayed at the same position for the same book. However, in the case of an electronic book, since it is necessary to display advertisements on terminals with various display sizes, the position of the advertisement with respect to the content is shifted. This is a particular problem when trying to select advertisement contents according to the content, because pages are allocated for each content content that can be displayed on the display in the electronic book as compared to a conventional web page.

  In addition, as described above, terminals are diversified and electronic books are being browsed on terminals having various display sizes. However, display sizes of general electronic book browsing terminals are often small. . For this reason, the proportion of the advertising area in the display area inevitably increases, and there is a possibility that the display of the advertisement may hinder browsing of the electronic book. In this case, it is also conceivable that the reader of the electronic book instills discomfort rather than attraction for the displayed advertisement.

<First implementation mode>
FIG. 1 is a conceptual diagram showing a system relating to advertisement distribution and advertisement display of the present invention.
The terminal 1 includes a display device 3 for browsing an electronic book. The terminal 1 communicates through a single or another communication device, and can access the advertisement distribution server 4 via a network such as the Internet. The terminal 1 includes content display means for displaying the content of the electronic book on the display device 3. The content to be displayed may be displayed by calling and displaying electronic book data stored in the storage area of the terminal, or may be in a streaming format for browsing while receiving from the electronic book providing server via the network.

  Hereinafter, the entire system of the present invention including the configuration of the terminal 1 and the advertisement distribution server 4 of FIG. 1 will be described along the steps of advertisement distribution. FIG. 2 is a flowchart showing an advertisement display step on the terminal side in an embodiment of the advertisement distribution system according to the present invention (first embodiment), and FIG. 3 is an advertisement distribution on the advertisement distribution server side of the same advertisement distribution system. It is a flowchart which shows a step.

  First, in the first embodiment of the present invention, a terminal (hereinafter referred to as a terminal) equipped with an electronic book browsing application records an electronic book display means for displaying the contents of the electronic book, and a browsing history for recording the browsing status of the user. Recording means, advertisement display starting means for starting advertisement display based on browsing history, and target area for determining the range of target content in order to determine the content of the advertising content according to the content content of the electronic book It includes at least determination means and extraction means for extracting keyword information for determining advertisement content to be distributed from the target area.

The electronic book display means is linked to the browsing history recording means, and the browsing history is recorded in the browsing history recording means in accordance with the browsing action. As an example of the browsing history, information on the currently displayed page (final browsing page) is recorded. As a typical mode, the terminal reads the information of the last viewed page from the storage area when the application is activated. Each time the user turns the page, the data in the storage area is updated with the new display page as the final viewing page. In addition, data indicating a user's browsing state is recorded in the internal work area as will be described later.
Further, the browsing history records information on the electronic books that have been browsed in the past, bookmarks (specified predetermined pages) written by the user in the electronic books, and markers (specified predetermined areas).

  The advertisement display starting means is the advertisement display step shown in FIG. 2 when the data indicating the browsing state of the user's electronic book recorded in the internal work area when browsing the electronic book satisfies the condition based on the set condition. Is started (S11). As an activation condition of the advertisement display function, it is preferable to determine based on an index indicating that the user has left the electronic book viewing state. Specifically, the interval between the pages of the electronic book is measured, and when an operation such as changing the page is not performed for a predetermined period of time or when the average page turning interval of the user is When the page is not switched more than a certain amount (for example, when 10 times the average page turning interval has elapsed), the activation condition of the advertisement display activation unit is assumed to be satisfied. Note that the page turning interval can be measured by recording time when the user performs an operation (for example, click, tap, slide, etc.) that requests display of the next page. There is no particular limitation as long as a user can determine whether or not the user is browsing an electronic book. For example, the determination may be made using a digital camera capable of recognizing the user's face, an acceleration sensor / gyro sensor capable of detecting the tilt of the terminal, or the like. Alternatively, the advertisement display step may be started by indicating that the user is in the browsing suspended state by using a switch such as a pause button. These activation conditions can be used in any combination.

  When the advertisement display step is started by the advertisement display activation means, the terminal determines a content area to be subjected to keyword extraction in order to display an advertisement linked to the contents of the electronic book (S12). The target area is determined based on the setting information recorded in advance in the terminal and the browsing history recorded according to the browsing of the electronic book by the user by the browsing history recording unit. The setting information may be read from the setting file when the browsing application is started. It is also possible to read the attribute information of the electronic book when the browsing application is activated and select the setting file according to the type of the electronic book. In the case of an electronic book format written in a markup language, the electronic book attribute information is described in a format such as <meta name = "keywords" content = "keyword 1, keyword 2, keyword 3 ..." />, for example. be able to. For e-book attribute information, for example, rough classifications such as magazines, novels, non-fiction, etc., fine classifications such as weekly magazines for men, monthly magazines for fashion, etc., and the direction of content, such as business, hobbies, education, etc. From the classification, detailed classification such as fishing and mathematics can be included.

  The target area determining means determines a specific target area with reference to the browsing history based on the setting information that sets which range is the target. For example, in the setting information, when the display page, bookmark page, and marker area are set as the target area, the corresponding information is extracted from the data recorded in the browsing history. The target area. The setting information may be set so that the last several pages from the last browsing page are the target area (final browsing area), and if the contents of bookmarks and markers are related to the last browsing page ( For example, it may be set so as to be included in the target area only when belonging to the same chapter or when similar meaning is given by metadata or the like. Furthermore, when information of another electronic book browsed in the past is included as the browsing history, a bookmark or marker area of the electronic book may be included in the target area. In addition, when the content is structured and divided into chapters, the target area may be within a chapter including the final browsing page.

  Next, keywords are extracted with the determined target area as a range (S13). This keyword is used to distribute advertisements related to the content being browsed. Examples of keyword extraction methods include the following. However, various methods used in advertisement distribution on a web page can be employed for keyword extraction as in Patent Document 1 listed in the prior art, and the present invention is not limited to the following examples.

(Extraction of frequent words)
Words that are repeatedly used in the text of the contents of the electronic book are considered to have high importance, and are therefore ranked by appearance frequency, and the higher word is used as a keyword. In addition to the simple appearance frequency, generally, the extraction accuracy can be improved by weighting and ranking words with low appearance frequency.
(Use of attribute information)
Depending on the format of the electronic book, keywords can be embedded in the content as metadata. If this metadata is embedded as region attribute information such as chapters, pages, or articles in the form of tags indicating attribute information, for example, keywords described in the target region are extracted by reading the tags. be able to. Moreover, you may add the keyword which shows the attribute information (book attribute information) of the whole book.
(Extraction of headwords)
Especially in magazines and papers, the contents are often structured and have headings, so keywords are extracted from the words used in the headings. Also, in order to facilitate the extraction of keywords for headlines in electronic books, it is conceivable to have attribute information. In the following description, keyword extraction based on frequent words and attribute information will be described as an example. However, the present invention includes an embodiment in which attribute information is replaced with a headword to extract keywords.

  The keyword extraction methods may be used in any combination. The keyword extraction method may be changed for each type of electronic book based on the attribute information of the electronic book. Furthermore, when the keyword extraction method is used in combination, the number of keywords can be determined based on a preset ratio from words extracted from each of book attribute information, region attribute information, and frequent words. That is, the specific gravity of the keyword extracted for each keyword extraction method is recorded in the setting information, and the ratio of the keywords extracted from each keyword extraction method follows the set ratio. In this way, by selecting a setting file (setting information) corresponding to the type of electronic book based on the book attribute information, it becomes easy to provide an advertisement that matches the type of content of the electronic book.

  For example, in the novel, there is almost no headline, and the image of the content part that the user has read immediately before becomes important. For example, the ratio of keyword extraction by extracting frequent words in the target area including the last viewed page is 70%, The keyword extraction ratio based on the book attribute information is 30%, and the keyword extraction ratio based on the region attribute information is 0%. In the case of weekly magazines, the content of each article is different, so the article attributes are important. Therefore, for example, the ratio of keyword extraction by extracting frequent words in the target area is 30%, the ratio of keyword extraction by book attribute information is 40%, and the ratio of keyword extraction by area attribute information is 30%.

  As another example, the keyword extraction may not be weighted on the terminal side, and the number of cases may be weighted for each keyword based on the setting information on the advertisement distribution side.

  The extraction of the keyword may be performed when the advertisement display step is started by the advertisement display activation means, or all keywords in the electronic book are extracted and stored in the storage area along with the browsing of the electronic book, When the area is determined, only the keywords within the range may be secondarily extracted and transmitted to the advertisement distribution server. Moreover, you may use combining these. For example, keywords for bookmarks and marker portions may be extracted when the user sets them, and the final viewing area may be performed after an advertisement display step is started by the advertisement display activation means.

  In addition, if keywords in electronic book contents are extracted in advance and an identifier for computer recognition is embedded, it is only necessary to collect the identified character strings included in the target area. Extraction is easy. For example, in the case of content written in a markup language, if keyword A is previously identified in a sentence, the keyword tag element name is used as a keyword, and <Keyword> Keyword A </ Keyword>. It can be described as The calculation load due to the keyword extraction process can be reduced.

  Next, an advertisement distribution request including the extracted keyword is transmitted to the advertisement distribution server (S14). The data to be transmitted is not particularly limited as long as at least the extracted keywords are included, but it is preferable to specify the number of advertisement contents to be requested. The number of advertisement contents to be requested can be set in advance by setting information. Alternatively, instead of transmitting the number of advertisement contents, terminal information (display device resolution, display size, etc.) is transmitted to determine the number of advertisement contents on the advertisement distribution server side according to the size of the display area. You may do it. Further, attribute information such as bibliographic information of the electronic book being browsed may be transmitted together.

  In addition, for each keyword or keyword group, data associated with the ratio or number of advertisement contents to be extracted may be transmitted to the advertisement distribution server as an advertisement distribution request. In this way, the number of cases can be weighted for each keyword on the advertisement distribution side based on the setting information of the terminal. For example, in the embodiment of FIG. 4, in the data transmitted at the time of the advertisement distribution request, the keywords are weighted for each extraction source such as the frequent word, the book attribute information, the region attribute information, The ratio of the number of advertisements for each keyword is calculated by weighting each bookmark). Such table information of the ratio of the keyword and the number of advertisements is transmitted to the advertisement distribution server. In particular, when the keyword extraction is not weighted on the terminal side as described above, the number of advertisement contents can be adjusted by the process on the advertisement server side, so that the processing load on the terminal side can be reduced.

  When the advertisement distribution server 4 receives the advertisement request (S21), the advertisement content to be transmitted to the terminal 1 is extracted based on the sent keyword (S23). The advertisement search means of the advertisement distribution server extracts the advertisement content related to the keyword from the advertisement content database. As an example of the advertisement content extraction method, a table in which an advertisement ID indicating each advertisement content is associated with a keyword is recorded in the advertisement attribute database as shown in FIG. 5, and a priority is determined for each advertisement. A keyword may be associated with a plurality of advertisement contents. The priority is for extracting the advertisement content from the one with the highest priority when the number of advertisement contents presented by the search is larger than the number of requested advertisement contents. Priorities may be provided for each of a plurality of keywords associated with each advertisement content.

  As one embodiment of the extraction of advertising content for a keyword, the number of items to be extracted for a certain keyword is determined, and the number of items determined in order from the advertising content with the highest priority of the keyword or the advertising content highly related to the keyword, What is necessary is just to extract. For example, when the number of keywords transmitted from the terminal is equal to the number of requested advertisement contents, one advertisement content is extracted for one keyword. In addition, as described above, when the advertisement distribution server receives data associating the ratio or number of advertisement contents to be extracted as an advertisement distribution request, the number of each keyword (in the case of ratio, the total advertisement contents scheduled to be distributed) (Multiply by the number)).

  In addition, if the number of ad content extracted by search for a keyword is less than the number of ad content scheduled to be delivered, the keyword thesaurus is used to determine the upper / lower relationship of words, partial / whole relationship, synonym relationship, The search range may be expanded from the synonymous relationship to the term related to the keyword to satisfy the requested number of advertisement contents.

  The advertisement distribution server 4 transmits the extracted advertisement content and completes the advertisement distribution step (S24). The data transmitted by the advertisement distribution server may include information such as keywords and priority associated with the advertisement content in addition to the advertisement content.

  When the advertising delivery fee model is determined according to the number of times the advertising content is displayed, the advertising content that is sent / transmitted to the terminal is extracted after the advertising content is extracted and before or after the transmission of the advertising content. It may be recorded in the advertisement history database. Furthermore, the advertisement history may be recorded in association with the attributes of the electronic magazine that is the target of advertisement distribution and the keyword that is the search source. As will be described later, even when the user performs an action such as clicking the advertisement content that is distributed and displayed on the terminal, the advertisement content is associated with the attributes of the electronic magazine and the keyword of the search source. If you record in the server's advertisement history database, you can see the interesting advertisements in the distributed advertisements, so the settings information on the terminal side and the search target of the advertisement content for the keyword are reflected in the results and adjusted In addition, efficient advertisement distribution can be performed according to the attributes and contents of the electronic book.

  The terminal 1 receives the advertisement content transmitted from the advertisement distribution server 4 (S15). The advertisement display means outputs / displays the advertisement content on the display device 3 (S16). 6 to 8 are schematic diagrams showing examples of advertisement display modes according to the present invention. In the example of FIG. 6, the advertisement screen is switched and displayed from the electronic book browsing screen. In the example of FIG. 7, an advertisement screen is displayed as an upper layer on the electronic book viewing screen. FIG. 8 shows an example in which an advertisement is displayed in a manner in which the character from which the keyword is extracted and the advertising content are visually linked, particularly when the advertising content is distributed based on the keyword in the browsing page. However, the advertisement display method that can be used in the present invention is not limited to the examples shown in FIGS.

  When the user touches the touch panel or operates the mouse on the advertisement display area of each advertisement content (the area where the text of the advertisement is surrounded by a frame line in the examples of FIGS. 6 to 8), You may make it perform actions, such as a display of detailed information, a change of advertising content, and the transfer to a website. At this time, as described above, data in which an electronic magazine attribute or a search source keyword is associated with the advertisement ID indicating the advertisement content is transmitted to the advertisement distribution server and recorded in the advertisement history database, so that the user is interested. You may make it record the advertisement which it had.

  The display of the advertisement is terminated by an operation suggesting that the user stops displaying the advertisement. For example, switch operation, touch panel touch in a region other than the advertisement display region, mouse operation, and the like. When the advertisement display is completed, the final browsing page of the electronic book is displayed, and browsing can be resumed.

  An electronic book to which the present invention can be applied is not limited in format and type as long as at least a part of the content can be read as text. This includes not only the case where the text is embedded as text, but also the case where the text is embedded as attribute information representing the content of the image or video. Accordingly, there are no restrictions on the content such as magazines, photo books, picture books, novels, and the like.

<Second embodiment>
FIG. 9 is a conceptual diagram showing another embodiment (second embodiment) of the system according to the advertisement display of the present invention. Items having the same functions as those in the first embodiment are given the same names. In the following description, operations different from those of the first embodiment will be described, and it is obvious that the items described in the first embodiment can be adopted for the other items, and therefore, redundant description will be omitted.

  In the second embodiment, the terminal 1 for browsing the electronic book is a terminal that realizes a method for displaying an advertisement when not connected to the network. The second embodiment differs from the first embodiment in that the terminal is provided with advertisement search means for distributing advertisements according to the extracted keywords.

  In the configuration of FIG. 9, a database of advertisement content and a database of advertisement attributes are stored in the terminal, and an advertisement display is extracted from the advertisement content stored in the terminal. The advertisement content database and the advertisement attribute database are downloaded simultaneously when, for example, an electronic book is downloaded to a terminal. Each step of displaying an advertisement in the mode of FIG. 9 can take the same configuration as that of the first embodiment except that there is no step of transmission / reception between the terminal and the advertisement distribution server as shown in FIG. The description is omitted.

  FIG. 11 shows an application example of the second embodiment. The advertisement content database and the advertisement attribute database are packaged together with the contents of the electronic book, and the advertisement search means of the terminal selects the advertisement contents in the electronic book package 5. Although different from the configuration of FIG. 9 in that it is extracted, the advertisement display step does not change. In this case, a keyword in the electronic book content may be extracted in advance, and an identifier that links the advertising content to the keyword may be embedded. The calculation load in the keyword extraction process at the terminal can be reduced. For example, in the case of XML format content, when the keyword B is identified in advance in the text and linked to the advertising content with the advertising ID 10001, the element name of the keyword tag is keyword and the attribute name of the advertising ID is ad_id. .. <Keyword ad_id = "10001"> Keyword B </ Keyword>... After the target area in the content from which the keyword is extracted is determined, the advertisement content linked by the identifier within the range can be extracted and the advertisement can be displayed. Therefore, the advertisement display shown in FIG. Steps S33 and S34 can be processed simultaneously.

  FIG. 12 shows another application example of the second embodiment. From the electronic book package 5 in which the database of advertisement contents and the database of advertisement attributes are packaged together with the contents of the electronic book, the database of advertisement contents and the database of advertisement attributes. Is stored in the storage area of the terminal 1, and the advertisement search means extracts the advertisement content from the advertisement content database and the advertisement attribute database stored in the terminal. By doing this, when the terminal can be connected to the network, update the advertising content database and advertising attribute database in the terminal, or add and update advertising content when a new e-book is read, and share You can do it.

  The second embodiment described above can be adopted in combination with the first embodiment. That is, when the advertisement display activation means starts the advertisement display step, the terminal is allowed to connect to the network, confirms that the connection is possible, and if the connection is possible, the first embodiment When the advertisement distribution request is made to the advertisement distribution server 4 and the distributed advertisement content is displayed and cannot be connected to the network as described in the above, in the electronic book package or the terminal according to the second embodiment.
