By managing the target value and the like, an appropriate operation according to the advertisement distribution capability of the advertisement distribution unit 5 is performed.

  As described above, the advertisement registration management device 9 manages the registration and management of advertisement information, the management of the number of advertisement distributions, the distribution target value according to the advertisement distribution capability, and the management function of the advertisement distribution apparatus 3. It is what has.

  Note that the advertisement distribution device 3 shown in FIG. 3 includes a filtering engine 6, an advertisement distribution engine 8, an advertisement distribution unit 5, an advertisement material server 11, and an advertisement registration management device 9. For example, any or all of the filtering engine 6, the advertisement distribution engine 8, the advertisement material server 11, and the advertisement registration management device 9 are built in the advertisement distribution unit 5, and the filtering engine 6, the advertisement distribution You may make it the structure which implement | achieves each structure and function of an engine, the advertisement material server 11, and the advertisement registration management apparatus 9 with the advertisement delivery part 5. FIG.

  Next, content advertisement category extraction processing, advertisement distribution processing, and advertisement category range expansion processing in the advertisement distribution system configured as described above will be described.

  First, content advertisement category extraction processing by the filtering engine 6 will be described with reference to FIGS. The content advertisement category extraction processing by the filtering engine 6 is performed by reading out new content from the content distribution server 12 via the communication network 20 when new content is stored in the content distribution server 12. This is a process for extracting in advance an advertisement category that matches the content of. FIG. 6 is a flowchart showing an advertisement category extraction process for content in the filtering engine 6, and FIG. 7 is a diagram showing an example in which advertisement categories extracted by the advertisement category extraction means are displayed in descending order of coincidence as content. is there.

  As shown in FIG. 6, the content data acquisition means 6 a of the filtering engine 6 shown in FIG. 5 first accesses the content on which the advertisement stored in the content database 14 of the content distribution server 12 is posted via the communication network 20. Then (step S1 shown in FIG. 6), content data is acquired (step S2). Further, the CSS information acquisition unit 6d acquires CSS information which is background color, character color data, and layout information from the content data (step S3). The CSS information is used to display the content and the advertisement on the user terminal 15 at the same time by adjusting the display color of the advertisement based on the character color and background color of the content and displaying the content in a balanced manner.

  Next, the filtering engine 6 cuts out the body data of the content from the content including the character information by the body cutting means 6b (step S4). Next, the text data clipped by the text cutout means 6b by the advertisement category extraction means 6c is matched with the words of the lower-layer advertisement category set in advance (step S5). Matching is to check how much the whole content body matches with the word of the lower advertisement category. When matching is performed by the advertisement category extraction means 6c, a matching degree that is a matching degree between the content body and the words of the lower advertisement category is calculated (step S6).

  In addition, the matching processing between the content text data and the advertisement category word in the advertisement category extraction unit 6c is performed using the advertisement category word as an index word, the frequency of use of the index word in the text, the use position, and the similarity to the index word. The word extraction and its use frequency, the distance (proximity) between index words, etc. are weighted by numerical values, and the numerical values are totaled to calculate the matching degree of each advertisement category in the lower layer. A plurality of techniques relating to matching between document information and index terms have been proposed, and it is possible to use them.

  Next, advertisement categories having a high degree of coincidence are arranged in order, and an advertisement category matching the content is extracted (step S7).

  FIG. 7 shows an example in which the advertisement category extraction unit 6c performs matching processing between the body of the blog as the content and the advertisement category, and the advertisement categories having a high degree of matching are sequentially displayed. As shown in FIG. 7, the matching degree of the advertisement category that matches the blog body is highest in the lower-level advertisement category “department / department store”, and “department / department store” most closely matches the content of the blog body. It is shown that. Next, “child-rearing / discipline”, “kindergarten / nursery school”.

  Next, the CSS information, the advertisement category NO, and the matching degree of the content data acquired in step S3 are stored in the category management database 7 (step S8).

  CSS information can also be acquired when displaying advertisements, but in order to reduce the time required for matching the content layout and the advertisement layout and to deliver the advertisement at high speed It is preferable to obtain CSS information of the content in advance.

  FIG. 8 is a diagram illustrating an example of data for each URL of content stored in the category management database 7 by matching the content with the advertisement category by the filtering engine 6 in a table format. As shown in FIG. 8, the category management database 7 stores the URL indicating the location of the content on the Internet, the background color of the content, the character color, and the advertising category having the highest matching degree with the advertising category number and the matching degree in order. is doing. In addition, retrieval and reading of data from the category management database 7 are performed using the URL as a key. Thus, by specifying the URL of the content, the advertisement category number, the matching degree, the background color of the content, and the like can be read from the category management database 7.

  As described above, the advertisement category extraction process of the content by the filtering engine 6 extracts the advertisement category that matches the content. As shown in FIG. 8, the advertisement category No., the degree of matching, the CSS information, etc. Is stored in the category management database 7 with the URL indicating the address as a key.

  Next, when the user terminal 15 browses the content stored in the content distribution server 12, the advertisement distribution processing for distributing the advertisement suitable for the content is shown in the flowcharts shown in FIGS. 2, 3, 5, and 9. This will be described with reference to the advertisement placement example shown in FIG. FIG. 9 is a flowchart illustrating an advertisement distribution process for distributing an advertisement suitable for content, and FIG. 10 is a diagram illustrating an example in which two advertisements are placed in the lower part of the page of the blog text on the display device of the user terminal. As shown in FIG. 10, the advertisement distribution process is a process for displaying an advertisement suitable for the content of the blog text below the blog text on the display device of the user terminal 15.

  First, the user terminal 15 shown in FIG. 3 accesses the content distribution server 12 that distributes content. Note that a script for accessing the advertisement distribution unit 5 of the advertisement distribution apparatus 3 is incorporated in the content of the content distribution server 12 in advance. The user terminal 15 receives the content HTML from the content distribution server 12 and displays the content. In addition, the user terminal 15 accesses the advertisement distribution unit 5 using a script incorporated in the content HTML. The advertisement distribution unit 5 receives the URL of the content output from the user terminal 15 by the URL acquisition unit 5a shown in FIG. 5 and the advertisement template information related to the advertisement placement (step S20 shown in FIG. 9). After receiving the URL and the advertisement template information, the advertisement distribution unit 5 outputs the URL (indicated by an arrow in FIG. 3) of the content acquired by the URL acquisition unit 5a to the filtering engine 6 (step S21). The filtering engine 6 reads out, from the category management database 7 shown in FIG. 8 using the URL as a key, an advertisement category having a high degree of matching corresponding to the URL, CSS information such as the background color and text color of the content, etc. (step S22).

  Next, the posted advertisement priority unit 6f of the filtering engine 6 shown in FIG. 5 performs a posted advertisement priority process for confirming whether the advertisement is registered in the order of the advertisement category having the high degree of matching selected in step S21. The posted advertisement priority process is to check whether an advertisement is registered in the advertisement category selected in the advertisement database 10, and in order to prevent an advertisement category from which no advertisement is registered from being selected. The selected advertisement category is preferentially selected (step S23).

  Next, when two or more advertisements are simultaneously placed by the competing advertisement exclusion means 6g of the filtering engine 6, a competing advertisement exclusion process is performed so that the two advertisements do not belong to the same advertisement category (step S24). In the competitive advertisement exclusion process, for example, when “life insurance / insurance” and “pension” shown in FIG. 2 are selected by the posted advertisement priority unit 6f, these advertisement categories belong to the middle layer of “money plan”. , It is determined that the advertisement category is the same, and the other advertisement category having a high degree of matching is selected.

  The advertisement category is determined by the posted advertisement priority means 6f and the competitive advertisement exclusion means 6g of the filtering engine 6 (step S25). The advertisement category acquisition means 5b of the advertisement distribution unit 5 acquires the advertisement category (indicated by an arrow in FIG. 3) determined from the filtering engine 6.

  Note that when the advertisement distribution process does not require the process of eliminating the competitive advertisement, the filtering engine 6 executes only the process of giving priority to the posted advertisement and does not perform the process of eliminating the competitive advertisement.

  Next, the advertisement distribution unit 5 outputs the advertisement category selected by the filtering engine 6 to the advertisement distribution engine 8 (step S26). The advertisement data selection means 8a of the advertisement distribution engine 8 searches the advertisement database 10 storing the advertisement data based on the advertisement category (shown by an arrow in FIG. 3) from the advertisement distribution unit 5 and distributes the advertisement ( Then, the advertisement data is output to the advertisement distribution unit 5 (step S27). Note that the advertisement data selection means 8a selects an advertisement with a high distribution priority from the actual value, target value, etc. of the number of distributions of each advertisement.

  After transmitting the advertisement data, the advertisement distribution engine 8 increments the advertisement distribution number by the advertisement distribution number counting means 8b and stores the distribution number for each advertisement in the advertisement database 10 (step S28). The number of distributions stored in the advertisement database 10 is used for managing the number of distributions for each advertisement in the advertisement registration management device.

  Next, the advertisement distribution unit 5 calls the distribution advertisement data from the advertisement database 10 and displays the advertisement display color so that the advertisement is displayed in a balanced manner based on the character color and background color of the content from the category management database 7. The distribution advertisement data is shaped and transmitted to the user terminal 15 (step S29). Since the image data of the distribution advertisement data is distributed from the advertisement material server 11, the URL of the advertisement material server 11 is incorporated in the distribution advertisement data.

  The user terminal 15 accesses the advertisement material server 11, and the advertisement image data is transmitted from the advertisement material server 11. Thereby, an advertisement is displayed on the user terminal 15 simultaneously with the content (step S30).

  Through the advertisement distribution process described above, as shown in FIG. 10, two advertisements are placed on the display device of the user terminal 15 at the lower level of the page of the blog text. By displaying an advertisement suitable for the content of the blog in the lower part of the page of the blog body, it is possible to provide an advertisement that the viewer is interested in, and to improve the advertising effect.

  Further, the advertisement distribution system 1 can provide a more detailed advertisement by connecting to an advertisement site when a viewer clicks an advertisement displayed on the user terminal 15 at the same time as the content. .

  Next, the advertisement category range expansion processing by the advertisement distribution number management means 9a of the advertisement registration management device 9 will be described with reference to the flowchart shown in FIG. FIG. 11 is a flowchart showing an advertisement category range expansion process by the advertisement registration management device 9. In the process of expanding the range of advertisement categories, if the target value for the number of advertisements delivered or the number of clicks falls below the actual number of deliveries during the advertisement delivery period, the scope of the advertisement category is automatically expanded to increase the opportunity for advertisement delivery. It is intended to increase. The advertisement category range expansion process is performed for each advertisement stored in the advertisement database 10 at regular time intervals (for example, 24 hours). In addition, the flowchart shown in FIG. 11 shows the range expansion process of the advertisement category using the number of advertisement distributions.

  As shown in FIG. 11, first, the advertisement registration management device 9 acquires an accumulated performance value of the number of advertisement distributions up to the present (hereinafter referred to as an accumulated distribution number actual value) from the advertisement database 10 (step S40). Next, the advertisement registration management device 9 acquires target values (hereinafter referred to as cumulative distribution number target values) L1 and L2 of the number of advertisement distributions up to the present from the advertisement database 10 (step S41). However, L1> L2, L1 is the cumulative distribution number target value of the expansion step 1, and L2 is the cumulative distribution number target value of the expansion step 2. For example, the cumulative distribution number target value L1 is set to 80%, and the cumulative distribution number target value L2 is set to 60%. Next, the achievement rate P is calculated from the cumulative distribution number actual value and the cumulative distribution number target value (step S42). However, the achievement rate P is represented by the achievement rate P = (cumulative delivery number actual value / cumulative delivery number target value) × 100.

  Next, it is checked whether P> L1 (step S43). When P> L1, since the cumulative delivery number actual value is equal to or greater than the cumulative delivery number target value, the advertisement category range expansion process is not performed. Next, it is checked whether the achievement rate P is L2 ≦ P ≦ L1. When L2 ≦ P ≦ L1, the achievement rate P is equal to or greater than the cumulative distribution number target value L2 and equal to or less than the cumulative distribution number target value L1, and therefore, the expansion step 1 for expanding the advertisement category range is performed. 12A and 12B are diagrams for explaining an expansion state of the advertisement category range in the expansion of the advertisement category range. FIG. 12A shows the lower-level advertisement category selected initially, and FIG. 12B shows a new selection in the expansion step 1. (C) is a diagram showing a newly selected lower layer advertisement category in the expansion step 2.

  As shown in FIG. 12 (b), the expansion step 1 selects a lower-layer advertisement category that is not selected from the middle-layer advertisement categories having a large number of selected lower-layer advertisement categories shown in FIG. 12 (a). To expand the scope of advertising categories. In the initial selection shown in FIG. 12A, the lower-level advertisement categories belonging to the middle-tier advertisement category No. 120 are the advertisement categories No. 121 and 122, and the remaining steps as shown in FIG. Advertisement category No123 is selected as the advertisement category.

  Further, when the achievement rate P is out of the range of L2 ≦ P ≦ L1, the achievement rate P is P <L2 and is less than the cumulative delivery number target value L2, so that the expansion step 2 for expanding the advertisement category range is performed. To. As shown in FIG. 12 (c), the expansion step 2 selects all lower advertisement categories in the middle advertisement category in which the lower advertisement category shown in FIG. Is to expand. The lower-layer advertisement categories belonging to the advertisement category Nos. 110, 120, and 210 in the advertisement category middle layer shown in FIG. 12A are initially selected. As shown in FIG. All lower-layer advertisement categories belonging to advertisement categories No. 110, 120, and 210 are selected as advertisement categories. The selected advertisement category is added to the advertisement category number column of the corresponding advertisement management number stored in the advertisement database 10 shown in FIG.

  If the target value for the number of ad delivery falls below the actual value of the number of deliveries during the ad delivery period due to the expansion process of the ad category described above, the target number of ad deliveries is set to automatically expand the range of the ad category. Can be approached. The cumulative distribution number target values L1 and L2 are set in advance, and are determined with reference to an advertisement distribution contract with the advertiser, past distribution result values, and the like.

  Also, the advertisement registration management device 9 returns the advertisement category to the initial selection state when the actual value of the number of distributions exceeds the target value of the number of advertisement distributions due to the expansion processing of the advertisement category that matches the content. The target value is managed.

  Also, instead of the number of advertisements delivered, the number of clicks on the displayed advertisement is used as the actual value, and the target value of the number of clicks for each advertisement is compared with the actual number. When the number of distributions falls below the target value, the range of the advertisement category may be automatically expanded.

  FIG. 13 is a table showing an example of the transition of the achievement rate P for each day with respect to the cumulative distribution number target value and the cumulative distribution number actual value during the distribution period. As shown in FIG. 13, the achievement rate P is 79% on the 8th day from the first day of the delivery date, and is less than 80% of the cumulative delivery target value L1, so the advertisement category range expansion step 1 is performed and the 9th day From the first onward, it is 80% or more of the cumulative distribution number target value L1.

  As described above, according to the advertisement distribution system, the advertisement distribution method, and the advertisement distribution program according to the present invention, the contents of content dealing with timely topics such as weblogs are matched with the advertisement categories to match the contents. Since the advertisement category registered is extracted and the viewer distributes the advertisement registered in the advertisement category when browsing the content, it is possible to simultaneously display the advertisement suitable for the content on the content of the user terminal. Can provide advertisements that people are interested in.

  In addition, the advertisement distribution system, the advertisement distribution method, and the advertisement distribution program according to the present invention automatically expand the range of the advertisement category when the target value of the advertisement distribution number falls below the actual value of the distribution number during the advertisement distribution period. In addition, since it has a function of expanding the range of the advertisement category that increases the distribution opportunity, the target number of distributions during the advertisement distribution period can be secured.

  In addition, according to the advertisement distribution system, the advertisement distribution method, and the advertisement distribution program according to the present invention, the information on the background color, the character color, and the layout is extracted from the content in advance and converted into data, so that the processing amount at the time of advertisement distribution Therefore, the speed of advertisement distribution can be increased.

  The advertisement delivery described above is for delivering an advertisement suitable for the content to the user terminal 15, but with reference to FIG. 14 for a delivery process for selecting an advertisement in consideration of the viewer's preference with an advertisement suitable for the content. To explain. FIG. 14 is a diagram illustrating an advertisement distribution process that takes into account the browser's preference. The URL 1 of the category management database 7 shown in FIG. 14 is the address of the content browsed by the viewer on the user terminal 15 last time, and the advertisement categories that match the content are “child-raising and discipline”, “baseball”, and “soccer”. is there. Among them, the advertisement categories in which advertisements are registered in the advertisement database 10 are “child-rearing / discipline” and “soccer” indicated by double circles. The user terminal 15 displays advertisements of the advertisement categories “child-rearing / discipline” and “soccer”, and when the viewer clicks the advertisement of “child-rearing / discipline”, the user preference data generating means of the advertisement distribution unit 5 Cookie information for identifying the advertisement category of the advertisement is issued from 5e, and the cookie information is stored in the user terminal 15. For the cookie information, the upper-layer or middle-layer advertisement category to which the lower-layer advertisement category belongs is selected. In FIG. 14, the middle-level advertisement category “child-rearing and child-rearing” to which the lower-layer advertisement category “child-rearing and discipline” belongs is selected as cookie information.

  Next, the user terminal 15 browses the content of URL 2 of the content distribution server 5. The advertisement categories that match the contents of URL 2 of the category management database 7 shown in FIG. 14 are “PC”, “Overseas Travel”, and “Kindergarten / Nursery School”. Among them, the advertisement categories in which advertisements are registered in the advertisement database 10 are “overseas travel” and “kindergarten / nursery school” indicated by double circles. The user preference data acquisition unit 5 f of the advertisement distribution unit 5 illustrated in FIG. 5 reads the advertisement category from the cookie information stored in the user terminal 15. The read advertisement category is “child-rearing and child-rearing”, and the advertisement categories registered for the content currently being browsed are “overseas travel” and “kindergarten / nursery school”.

  Next, the user preference selection means 6h of the filtering engine 6 shown in FIG. 5 confirms whether or not there is an advertisement category that has been registered for the currently browsed content in the lower layer of the previously viewed middle advertisement category. Determine the category. When there is no registered advertising category for the content being browsed, the range is expanded to all lower-level advertising categories that belong to the upper-level advertising category to which the previously viewed middle-level advertising category belongs. Check if there is a registered advertising category.

  The user preference selection unit 6h selects an advertisement category that matches the registered advertisement category of the currently viewed content from the lower layer of the advertisement category “childcare and child-rearing” of the middle layer viewed last time. In the example shown in FIG. 14, the registered advertisement category of the currently browsed content that matches the lower layer of the middle-tiered advertisement category “childcare and child-rearing” viewed last time is “kindergarten / nursery school”, and the advertisement category “kindergarten / nursery school” Is selected.

  In the advertisement stored in the database 10 shown in FIG. 14, the advertisement registered in the advertisement category “kindergarten / nursery school” is the advertisement B, and the advertisement distribution engine 8 selects the advertisement B and outputs it to the advertisement distribution unit 5. Then, the advertisement distribution unit 5 distributes the advertisement B to the user terminal 15.

  In addition, in the distribution process in which an advertisement is selected in consideration of the viewer's preference shown in FIG. 14, an advertisement category is issued as cookie information from the user preference data generating means 5 e of the advertisement distribution unit 5. Instead of using the terminal identification number, the advertisement category browsed last time may be identified. The terminal identification number is assigned so that each user terminal 15 can be identified, and the advertisement distribution unit 5 stores an advertisement category for each terminal identification number. The user preference data acquisition unit 5f of the advertisement distribution unit 5 reads the terminal identification number as cookie information stored in the user terminal 15, and determines the advertisement category browsed last time from the terminal identification number.

  As described above, the distributed advertisement is an advertisement suitable for the content to be browsed, and further an advertisement incorporating the viewer's preference is distributed, so that the advertising effect of the advertisement can be improved.
