Description

  The present invention relates to a distribution system, a distribution method, and a program.

  In recent years, the Internet has been actively used as an advertising medium. For example, it is widespread that an advertisement image or text called a banner is pasted on a Web (Web: World Wide Web) site (see, for example, Patent Documents 1 and 2). In particular, since site search using the Internet is often used, a promotion for attaching a banner to a search result of site search is widely performed. The searcher accesses various websites by links attached to banners attached to the website.

Since many such banner advertisements on the Internet are affixed, it is difficult for consumers to see, and in many cases, the effect of the advertisement cannot be fully exhibited. Further, in the case of site search, since the searcher mainly reads the text of the search result, it is often the case that he / she does not read the banner advertisement for the promotion target, and the content that the advertiser wants to advertise is not easily transmitted to the consumer. In particular, when the banner advertisement is text, it is often less readable than the image. In addition, since the size of the banner advertisement to be pasted on the search result site is often limited, it is difficult to obtain a sufficient advertising effect.

Embodiment 1 of the Invention

  First, the overall configuration of the advertisement distribution system according to the present invention will be described with reference to FIG. FIG. 1 is a schematic diagram showing an example of the overall configuration of an advertisement distribution system according to the present invention.

  As shown in FIG. 1, the broad advertisement distribution system includes a search server 1, an advertisement server 2, a client 3, and a communication network 4. Here, the search server 1 is communicably connected to the user client 3 via the communication network 4, and the advertisement server 2 is communicably connected to the search server 1 via the communication network 4.

  The search server 1 is configured by a so-called computer and functions as a search engine. Specifically, “YAHOO (registered trademark)”, “Google (registered trademark)”, “MSN (registered trademark),“ goo (registered trademark) ”. ) "," Infoseek (registered trademark) ", etc. It can be a search engine provided by a so-called portal site. As a suitable example, the search server 1 follows a link by an automatic patrol program. Therefore, the search server 1 searches for a desired website based on a search keyword from an unspecified number of websites. CPU 11, storage unit 12, communication control unit 13, RAM 14, search database (first database) 15 And a hardware configuration of the. Other output device such as a display, a keyboard, and an input device such as a mouse or the like, are omitted in FIG.

  The CPU 11 of the search server 1 functions as a control unit that executes various processes based on an OS program or application program stored in advance in the storage unit 12.

  The storage unit 12 includes internal storage means such as an EEP-ROM and a hard disk, and external storage means such as a flexible disk and a CD-ROM, and stores OS programs, application programs, and the like. The application program in this example includes various software programs such as a software program for creating web data (web engine) and an automatic patrol program for executing site search processing.

  The communication control unit 13 includes a connection interface to the communication network 4 and a communication control circuit. The communication control unit 13 can execute data communication with the user client 3.

  The RAM 14 is used as a work area for the CPU 11 and temporarily stores, for example, an execution part of the program and data used at the time of execution.

  The search engine database 15 is configured by storage means such as a hard disk or an optical disk, and is a database for the search server 1 to function as a search engine. The search engine database 15 stores a search keyword table and search result information indicating search results. These pieces of information are shown in FIGS. 2 (a) and 2 (b).

  As shown in FIG. 2A, the search keyword table includes a search keyword 151, a URL (Uniform Resource Locator) of a website including the search keyword, a domain, a site address 152 such as a URI (Uniform Resource Identification), a web Site content information 153, which is the content of the site, is stored and associated with each other. This search keyword table is recorded as needed by the search keyword and website address acquired by the automatic patrol program.

  As shown in FIG. 2B, the search result information includes site identification information 152, site title information 155, site summary information 156, etc., which are stored in association with each other.

  The site identification information 152 is identification information for identifying each website, such as the URL, domain, URI, and site ID in the search engine database 15 of each website. When the site identification information 152 is a site ID in the search engine database 15, the site ID is stored in association with the URL of each website. The site title information 155 is the title information of each website related to the search keyword, and the site summary information 156 is the summary information of each website related to the search keyword.

  The advertisement server 2 is configured by a so-called computer, and constructs a narrowly defined advertisement distribution system. The advertisement server 2 includes hardware configurations such as a CPU 21, a storage unit 22, a communication control unit 23, a RAM 24, and an advertisement database (second database) 25. In addition, although an output device such as a display and an input device such as a keyboard and a mouse are provided, they are omitted in FIG. Here, the CPU 21, the storage unit 22, the communication control unit 23, and the RAM 24 of the advertisement server 2 have the same configuration as the CPU 11, the storage unit 12, the communication control unit 13, and the RAM 14 of the search server 1, and thus the description thereof is omitted. .

  The advertisement database 25 is configured by storage means such as a hard disk or an optical disk, and is a database for adding to search results. In the advertisement database 25, site identification information 251, advertisement title information 252, advertisement link destination information 253, and the like are stored in association with each other as advertisement information added to the search result information. Here, the advertisement information is information that is an object of interest of the user. In other words, the advertisement information includes not only information that produces advertising effects such as general advertisements, but also specific information that is specifically transmitted to the user. Each of these pieces of information is shown in FIG.

  The site identification information 251 is identification information for identifying each site, and is the URL, domain, URI, site ID in the advertisement database 25, and the like. When the site identification information 251 is a site ID in the advertisement database 25, the site ID is stored in association with the URL of each website. In this case, the site IDs in the databases 15 and 25 are associated so that the search engine database 15 and the advertisement database 25 are linked. As an example, each database 15 and 25 can manage various information by a common site ID. The advertisement title information 252 is text information indicating an advertisement title to be added, image information such as an icon, and the like, and the advertisement link destination information 253 is a URL of an associated advertisement site.

  Note that the narrowly defined advertisement distribution system according to the present embodiment can be configured by a single computer instead of a plurality of physically separate computers, and the hardware configuration thereof is shown in FIG. It is not limited to. Further, other servers such as a firewall server and a hardware configuration may be provided.

  The client 3 is a personal computer (PC) with a so-called Internet connection function used by a user, such as a control unit such as a CPU and a ROM, a storage unit such as a RAM and a hard disk, a communication control unit such as an interface, an input key, and the like Input means, and output means such as a display.

  The user client 3 has a browser program stored in a memory, and can receive web data transmitted from the search server 1 and display it on a display. In the advertisement distribution system according to the present invention, the client 3 may be any terminal that can communicate with the servers 1 and 2 via the communication network 4. For example, various terminals such as a mobile terminal and a mobile phone can be used instead of the client 3 which is a personal computer.

  Next, the outline of the processing of the advertisement distribution system according to the present invention will be described using the schematic diagram shown in FIG.

  Assume that the client 3 has accessed the search server 1. In this case, the search server 1 receives an access request from the client 3 and generates a top page of the search site in response to the access request. The search server 1 transmits the generated top page to the client 3, and the client 3 displays the received top page on the display.

  When the user inputs a search keyword on the top page of the displayed search site, the client 3 transmits the search keyword to the search server 1. The search server 1 acquires a search result from the search database 15 based on the received search keyword. At the same time, the search server 1 makes a transmission request for advertisement information to the advertisement server 2 in accordance with the acquired search result. The advertisement server 2 transmits advertisement information corresponding to the search result to the search server 1 based on the received advertisement information transmission request. The search server 1 links the acquired advertisement information to the search result, and transmits the search result to which the advertisement information is linked to the client 3. The client 3 displays the received search result together with the advertisement information on the display. By selecting this advertisement information, an advertisement site linked to the advertisement information can be directly displayed.

  Next, detailed processing of the advertisement distribution system according to the present invention will be described using the flowchart shown in FIG.

  The client 3 receives the search keyword (S101), and transmits the search keyword to the search server 1 along with the start of the search process (S102). Specifically, when a search keyword is input using the input key of the client 3, the search keyword is input to the control unit of the client 3 via an interface or the like. This control unit inputs a search keyword to the communication control unit by the web browser program, and is transmitted from the communication control unit to the search server 1. The transmitted search keyword is sent to the search server 1 via the communication network 4.

  When receiving the search keyword via the communication network 4 (S103), the communication control unit 13 of the search server 1 inputs the received search keyword to the control unit configured by the CPU 11 or the like. The control unit executes search processing based on the search keyword and stores search result information in the search database 15 (S104).

  For example, the search server 1 can be a robot search type search engine. In this case, when executing the search process, the control unit of the search server 1 reads the automatic patrol program into the RAM 14, and automatically follows the hyperlink of the website according to the program, and converts the contents of the web page into the site contents. Information 153 is recorded as needed. The control unit analyzes the link structure of the website and the content of the web page, and stores the search keyword 151 included in the web page and the site address 152 of the website in the search keyword table.

  When executing the search process, the control unit reads the site content information 153 associated with the search keyword received by the search keyword table. The control unit generates site title information 155 and site summary information 156 from the read site content information 153 and stores them in the search database 15 based on the site identification information 154. As a result, the search result information is stored in the search database 15. When the URL of the website is used as the site identification information 154, the site address 152 associated with the search keyword received by the search keyword table is read and stored as the site identification information 154.

  The control unit once reads the stored search result information, extracts the site identification information 152 from the read search result information (S105), and generates a request for transmitting the advertisement information to the advertisement server 2 (S106). The site identification information 152 is input to the communication control unit 13 together with the transmission request, and the communication control unit 13 transmits the site identification information 152 and the transmission request to the advertisement server 2 (S107). The site identification information 152 and the transmission request are sent to the advertisement server 2 via the communication network 4.

  When the communication control unit 23 of the advertisement server 2 receives the site identification information 152 and the transmission request from the search server 1 via the communication network 4 (S108), the received site identification information 152 and the transmission request are received from the CPU 21 or the like. Input to the configured control unit. Based on this transmission request, the control unit acquires advertisement information corresponding to the site identification information 152 from the advertisement database 25 (S109), and inputs this advertisement information to the communication control unit 23. The advertisement information is transmitted from the communication control unit 23 to the search server 1 and sent to the search server 1 via the communication network 4 (S110).

  For example, in FIG. 3, it is assumed that the site identification information 152 of the search result information read by the control unit of the search server 1 is “0002”. In this case, the control unit of the advertisement server 2 reads the advertisement title information 252 and the advertisement link destination information 253 corresponding to the site identification information “0002”. Specifically, “auto insurance” as the advertisement title information 252 corresponding to the site identification information “0002”, “http: //www.def...” As the advertisement link destination information 253, and other advertisement title information 252. "Life insurance" as the advertisement link destination information 253, "http: //www.mno ...", etc. are read because they correspond to the identification information at this time.

  The control unit of the search server 1 receives the advertisement information from the advertisement server 2 (S111), and reads the search result information stored in the search database 15. The control unit associates the advertisement information with the search result information, and generates search result information with advertisement indicating the search result information to which the advertisement is added (S112). The control unit inputs the generated search result information with advertisement to the communication control unit 13, and the communication control 13 transmits the search result information with advertisement to the client 3 (S113). The communication control unit of the client 3 receives the search result information with advertisement via the communication network 4 (S114), and inputs this search result information with advertisement to the control unit. The control unit of the client 3 generates search result display information for displaying it from the input search result information with advertisement, and displays the search result display information on the display (S115).

  FIG. 5 shows an example of a display window displayed on the display of the client 3. As shown in FIG. 5, in the display window 50, the search result item 51 indicating the site title information 155 is displayed in a text format in the same manner as in a general display window, and below each web indicating the site summary information 156. A brief summary 52 of the site is displayed in text format. When the site identification information 152 is a website URL, it is displayed below the summary as the URL of each item.

  The advertisement information added to the search result information is displayed as an advertisement link 53 in a space where no text such as the search result item 51 or the summary 52 is displayed in the display window 50. Specifically, it is displayed in a vacant space between the general advertisement 54 displayed conventionally and the search result item 51 and summary 52. For example, in FIG. 5, it is displayed in an empty space to the right of the search result item 51. More specifically, when the user performs a site search with the keyword “insurance”, “insurance *****”, “XX insurance ...”, etc. are displayed as the search result item 51, and this Next to the item 51, “auto insurance”, “life insurance”, and “travel insurance” are displayed. When the user selects the advertisement link 53, the linked advertisement page is displayed.

  Subsequently, the advertisement registration process in the advertisement server 1 according to the present invention will be described in detail.

  When an administrator or the like of the advertisement server 2 inputs the advertisement title information 252 and the advertisement link destination information 253 using an input key or the like, these information 252 and 253 are input to the control unit of the advertisement server 2. The control unit stores the input advertisement title information 252 and advertisement link destination information 253 in the advertisement database 25 in association with the site identification information 152. FIG. 6 shows an example of a display window for setting registration.

  As shown in FIG. 6, in the display window 60, advertisement item tabs 611 to 614 are provided and classified based on these. Each of the advertisement item tabs 611 to 614 is provided with a title input field 62 for inputting advertisement title information 252 and a link address input field 63 for inputting a link destination address. When the user inputs the title and the link destination address of the title in these input fields 62 and 63 and clicks the “new registration” icon 64, the advertisement title information 252 and the advertisement link destination information 253 are displayed in the site identification information 152. Correspondingly, it is stored in the advertisement database 25. Further, when the advertisement title information 252 and the advertisement link destination information 253 in the advertisement database 25 are updated, the user inputs the title and the link destination address of the title in the input fields 62 and 63, and the “update” icon Click 65.

  As described above, in the advertisement distribution system according to the present invention, the advertisement information is acquired based on the search result information and displayed together with the search result information. As a result, it is possible to clearly display the advertisement desired by the user on the display window on which the search result is displayed. In particular, if only the search result item 51 is displayed, it is often difficult to determine whether or not a desired site exists in the site indicated by the item 51. By displaying the advertisement link 53 together with the search result item 51 as in the present invention, the user can easily find the site he / she wants to search by simply looking at the search result list.

  Furthermore, the advertisement owner can limit advertisements that the user wants to convey to the user, thereby improving the advertising effect. In particular, the advertisement that the advertisement owner wants to convey to the user is likely to change from time to time, and it is preferable to update and reflect the advertisement immediately in order to convey it immediately. Since the advertisement information in the advertisement database 25 can be easily updated as in the present invention, it is possible to present to the user an advertisement that is desired to be transmitted from time to time.

  In the advertisement distribution system according to the present invention, the search server 1 is preferably a robot type search engine, and a search keyword table is created while visiting an unspecified number of websites and stored in the search data table 15. In such a robot-type search engine, since there are an unspecified number of websites to be visited and searched, only various processes such as a search keyword table creation process and a search process based on a search keyword are significant.

  Such a robot type search engine stores at least site identification information such as a URL, a domain, and a URI of a website associated with a search keyword in the search database 15. In the present invention, advertisement information is managed based on the stored site identification information, and the advertisement information is added to the search result information via the site identification information. Therefore, even if the search result information is generated by a robot-type search engine that requires various processes, it becomes easy to add advertisement information to the search result information.

  Further, the conventional general advertisement 54 is associated with the search keyword and extracted based on the search keyword. On the other hand, the advertisement link 53 in the present invention is associated with the site identification information of the website extracted by the search, and is extracted based on the site identification information. As a preferred example, when the site identification information is the URL of the website, the advertisement information can be displayed in association with the URL of the website extracted as a search result. In other words, while the advertisement distribution for each search keyword is conventionally performed, the present invention enables the advertisement distribution for each website. Thus, in the advertisement distribution system according to the present invention, an advertisement is added for each site identification information of the searched website. Therefore, unlike the case of using the search keyword, the advertisement can be distributed for each searched website. it can.

  In particular, in the robot type search engine described above, it is necessary to avoid an increase in processing and a decrease in search speed, and therefore, advertisements are not associated with each searched website and distributed. As a result, it is assumed that the website the user wants is somewhere in the many websites that are extracted in the search results, and even though the number of website searches and the search accuracy are increased, advertisements are distributed for each website. I never did. In this regard, by associating site identification information and advertisement information as in the present invention, advertisements can be easily distributed for each website.

Embodiment 2 of the Invention
In the first embodiment, the configuration in which the advertisement information is acquired based on the site identification information 152 of the search result information has been described. However, the advertisement information can be narrowed down based on the search keyword from the client 3 in addition to the site identification information 152. it can. Note that the advertisement distribution system in the second embodiment is the same as that in the first embodiment, and the description thereof is omitted here.

  An outline of the process of the advertisement distribution system according to the second embodiment will be described with reference to the schematic diagram of FIG. As illustrated in FIG. 7, the search server 1 makes a transmission request for advertisement information to the advertisement server 2 according to the acquired search result. At this time, the search server 1 transmits a search keyword together with this transmission request. The advertisement server 2 transmits the advertisement information corresponding to the search result and the search keyword to the search server 1 based on the received advertisement information transmission request. The search server 1 links the acquired advertisement information to the search result, and transmits the search result to which the advertisement information is linked to the client 3. The client 3 displays the received search result together with the advertisement information on the display. At this time, only the advertisement related to the search keyword input at the time of the search is displayed.

  The flowchart of FIG. 8 shows detailed processing of the advertisement distribution system according to the second embodiment. As shown in FIG. 8, the search server 1 executes a search process based on the received search keyword, and stores search result information in the search database 15 (S101 to S104). The control unit extracts the site identification information 152 from the search result information (S105), and generates a transmission request for advertisement information to the advertisement server 2 (S106). The control unit inputs the site identification information 152 together with the transmission request to the communication control unit 13, and the communication control unit 13 transmits the site identification information 152 and the transmission request to the advertisement server 2. At this time, the control unit inputs the search keyword together with the site identification information 152 and the transmission request to the communication control unit 13, and the communication control unit 13 transmits them to the advertisement server 2 (S137).

  The communication control unit 23 of the advertisement server 2 receives the site identification information 152 and the transmission request from the search server 1 and inputs them to the control unit (S138). The control unit acquires advertisement information corresponding to the site identification information 152 from the advertisement database 15 based on the transmission request. At this time, the control unit acquires advertisement information based on the search keyword in addition to the site identification information 152 (S139). For example, in FIG. 7, when the search keyword is “insurance”, the control unit displays “auto insurance” as the corresponding advertisement title information 252 and “http: //www.def·・ ・ "" Is read. The control unit inputs the acquired advertisement information to the communication control unit 23, and the communication control unit 23 transmits the advertisement information to the search server 1 (S140). Thereafter, the search server 1 adds the received advertisement information to the search result information (S142), and transmits the search result information with advertisement to the client 3 (S143). The client 3 receives the search result information with advertisement (S144) and displays it (S145).

  As described above, in the advertisement distribution system according to the second embodiment, the advertisement information is limited based on the search keyword. This makes it possible to more clearly display an advertisement requested by the user on the display window on which the search result is displayed. In addition, the advertisement owner can limit advertisements that the user wants to convey to the user, and the advertising effect can be further improved.

Embodiment 3 of the Invention
In the first embodiment, the advertisement information is displayed beside each item of the search result. However, when the space is small, the number of advertisement links that can be displayed may be limited. Specifically, the number of characters that can be input to the title input 62 in the display window 60 shown in FIG.

  FIG. 9 shows an example of a display window for setting registration in the third embodiment. As shown in FIG. 9, in the case of providing such a character number limitation, a notice “up to 8 full-width characters” is provided next to the title input field 62 of the display window 60, or next to the link address input field 63. A cautionary note such as “Within 100 characters” is provided.

  In the third embodiment, the following registration process is executed. When an administrator or the like of the advertisement server 2 inputs the advertisement title information 252 and the advertisement link destination information 253 using an input key or the like, these information 252 and 253 are input to the control unit of the advertisement server 2. The control unit performs a process for determining the number of characters of the advertisement title information 252. Specifically, the control unit requests the input again when the number of characters of the advertisement title information 252 exceeds a predetermined number of characters, and when it does not exceed, the input advertisement title information 252 and advertisement link destination information. 253 is associated with the site identification information 152 and stored in the advertisement database 25.

  As described above, by limiting the number of characters of the advertisement title information 252, the space of the advertisement link 53 can be saved, and the advertisement can be efficiently performed.

Embodiment 4 of the Invention
In the present embodiment, the advertisement information is extracted based on the site identification information 152 and the search keyword from the client 3. This point is the same as the second embodiment of the invention. It is the same. However, the mechanism for extracting the advertisement information is the same as that in the second embodiment. And different. In the present embodiment, the advertisement information to be extracted (to be narrowed down) is determined based on the parameter P1 set in advance by the advertiser and the parameter P2 whose value is set based on the search keyword. This different point will be particularly described below.

  First, the background of this extraction method will be described. FIG. 10A shows a configuration of a search result display screen according to the present embodiment. As shown in FIG. 10A, three advertisement links 53 are displayed corresponding to the items 51. In other words, three or less advertisement links 53 are displayed corresponding to the item 51.

  Specifically, as shown in FIG. 10A, advertisement links 53a1, 53a2, and 53a3 are displayed corresponding to the item 51a. Corresponding to the item 51b, advertisement links 53b1, 53b2, and 53b3 are displayed. Corresponding to the item 51c, advertisement links 53c1, 53c2, and 53c3 are displayed.

  Next, the structure of the table stored in the advertisement database 25 according to the present embodiment is shown in FIG. In the present embodiment, four advertisement titles A to D are associated with certain site identification information.

  Specifically, as shown in FIG. 10B, corresponding to ID0001, the advertisement title A “digital camera”, the advertisement title B “film camera”, the advertisement title C “single-lens reflex camera”, and the advertisement title D “ Inkjet printer "is associated. Corresponding to ID0002, advertisement title A “automobile insurance”, advertisement title B “motorcycle insurance”, advertisement title C “water bike insurance”, and advertisement title D “airplane insurance” are associated. Corresponding to ID0003, advertisement title A “real estate general”, advertisement title B “apartment information”, advertisement title C “land information”, and advertisement title D “detached house information” are associated.

  As is apparent from the description of FIG. 10A, the number of advertisement links 53 displayed in association with one item 51 is three. As is clear from the description of FIG. 10B, the number of advertisement titles associated with one site identification information is four. That is, in the present embodiment, the number of advertisement links 53 displayed in association with one item 51 is smaller than the number of advertisement titles associated with one site identification information.

  In such a case, three advertisement titles are extracted from the four advertisement titles included in the table stored in the advertisement database 25. The advertisement title is extracted using a predetermined algorithm as described later. Thereby, the convenience for both the advertiser side and the client side can be improved.

  Embodiment 2. FIG. As described in the above, when the algorithm that determines whether or not the search keyword is included in the advertisement title cannot extract the number of advertisement titles corresponding to the number of advertisement links (the advertisement arranged in the vicinity of the item 51) Space for displaying the link 53 may be wasted). Also, it is not possible to prioritize advertisement titles.

  Hereinafter, an advertisement title extraction method will be described. As shown in FIG. 10B, in the present embodiment, each row (each group) specified from the site identification information is provided with fields P1, P2, and T for each of the advertisement titles A to D. . P1 is a value set in advance by the advertiser (a value set in advance). P2 is a value determined based on the search keyword (variation value based on the search keyword). T is the total value of P1 and P2. Note that it is optional whether or not to provide fields for inputting P2 and T. P2 and T may be limited to numerical values stored in a temporary storage device (memory or the like) in the course of program execution. In addition, the arithmetic processing regarding P1, P2, and T is implement | achieved when the program stored in the memory | storage part 22 of the advertisement server 2 is run by CPU21.

  In the present embodiment, advertisement titles are extracted in descending order of the total value of T. That is, the advertisement titles are ranked in consideration of both P1 set by the advertiser and P2 determined based on the search keyword from the client 3, and the advertisement titles to be displayed are extracted. By using such an algorithm, items related to the item that the client 3 is searching for can be preferentially displayed on the screen of the client 3. In addition, items that the advertiser wants the client 3 to know can be preferentially displayed on the screen of the client 3.

  Here, it demonstrates concretely using FIG. As shown in FIG. 11A, it is assumed that the advertiser is a XX camera of a major home appliance mass retailer. As shown in FIG. 11B, it is assumed that the camera is input from the client 3 as a search keyword. When a camera is input from the client 3, it is displayed on the screen of the client 3 as shown in FIG.

  FIG. 11D shows an initial state of a table stored in the advertisement database 25. As shown in FIG. 11D, corresponding to ID0001, advertisement titles A to D and necessary items are input to these advertisement link destinations as described above. Further, P1 = 3 is input to P1 of the advertisement title A. Further, P1 = 1 is input to P1 of the advertisement title B. Also, P1 = 2 is input to P1 of the advertisement title C. Further, P1 = 9 is input to P1 of the advertisement title D.

  For example, P1 is set under the following circumstances. Since “XX Camera” is at the end of the year, we would like a wide range of consumers to visit the website of the advertisement title D “inkjet printer” (link destination of the advertisement title D). Therefore, the value of P1 of the advertisement title D is set to 9. We also want to strengthen sales in the order of digital cameras, single-lens reflex cameras, and film cameras. Therefore, P1 of the advertisement title A (digital camera) is set to 3, P1 of the advertisement title C (single-lens reflex camera) is set to 2, and P1 corresponding to the advertisement title B (film camera) is set to 1. Yes.

  FIG. 11E shows a table after P2 is input. As described above, P2 is a value determined based on the search keyword from the client 3. Here, P2 = 1 is set when the character string of the search keyword is included in the character string of the advertisement titles A to D (so-called partial match). As shown in FIG. 11E, the advertisement title A (digital camera) includes characters corresponding to the search keyword (camera). Therefore, P2 of the advertisement title A is set as P2 = 1. Similarly, P2 of the advertisement title B is set as P2 = 1. Similarly, P2 of the advertisement title C is set as P2 = 1. The advertisement title D (inkjet printer) does not include characters corresponding to the search keyword (camera). Accordingly, P2 = 0 is set for P2 of the advertisement title D.

  FIG. 11F shows a table after T is input. As described above, T is the total value of P1 and P2. The result of T = P1 + P2 = 3 + 1 = 4 is set for T of the advertisement title A. The result of T = P1 + P2 = 1 + 1 = 2 is set for T of the advertisement title B. The result of T = P1 + P2 = 2 + 1 = 3 is set for T of the advertisement title C. The result of T = P1 + P2 = 9 + 0 = 9 is set for T of the advertisement title D.

  When the ad titles A to D are arranged in descending order of the value of T (the ad titles A to D are ranked), the ad title D (inkjet printer), the ad title A (digital camera), and the ad title C (single-lens reflex camera) , Advertisement title B (film camera). As described above, the number of advertisement links 53 that can be displayed on the screen of the client 3 is three. Therefore, here, the advertisement title D (inkjet printer), the advertisement title A (digital camera), and the advertisement title C (single-lens reflex camera) are specified. The advertisement server 2 transmits information about the advertisement title D, the advertisement title A, and the advertisement title C (advertisement title / advertisement link destination) to the search server 1.

  Note that the number of advertisement links 53 may be set in advance in a field of another table in the advertisement database 25. Further, each time an inquiry about advertisement information is made from the search server 1, the number of advertisement links or 53 may be notified from the search server 1 to the advertisement server 2. Then, the program stored in the advertisement server 2 extracts the number of advertisement titles corresponding to the number of advertisement links 53 that are notified or set.

  As is clear from the above description, each advertisement title also functions as an index of advertisement link destinations, P1, P2, and T. In other words, the advertisement title is index information. In addition to the advertisement title, index information may be set in the table.

  Further, for convenience of explanation, the above-described information using the advertisement title as an index is also referred to as unit information. In this embodiment, since the number of unit information exceeds the number of advertisement links, it is necessary to extract the number of unit information corresponding to the number of advertisement links. Here, as described above, the unit information is ranked based on T (third parameter) determined from P1 (first parameter) and P2 (second parameter) set for each unit information. Then, unit information to be transmitted is acquired from the ranked unit information in descending order of the value of T.

  FIG. 12 illustrates a program execution procedure in the present embodiment. Embodiment 2. FIG. Is different from S139.

  As shown in FIG. 12, after S138, a row of a table stored in the advertisement database 25 (a group having ID as an index) is specified based on the ID (S139a). In the specified line, the advertisement information of the advertiser is input.

  Next, P2 is set (S139b). That is, it is determined whether or not the character string of the search keyword is included in the character string of the advertisement title (so-called partial match search). When the character string of the search keyword is included in the character string of the advertisement title, P2 = 1 is input. When the character string of the search keyword is not included in the character string of the advertisement title, P2 = 0 is input. As described above, P2 may be temporarily stored in a storage device such as a memory.

  Next, the total value T is set (S139c). Specifically, the value of P1 and the value of P2 are added for each advertisement title, and a total value T is set. As described above, T may be temporarily held in a storage device such as a memory.

  Next, the total value T is compared (S139d). Specifically, the advertisement titles are ordered in descending order of the total value T. In other words, the unit information is ranked in descending order of the total value T.

  Next, the advertisement information transmitted to the search server 1 is acquired (S139e). Here, the top three advertisement titles are preferentially specified, and advertisement information including those advertisement titles is acquired. In other words, the top three unit information is acquired.

  Then, advertisement information (advertisement title, advertisement link destination) regarding the identified advertisement title is transmitted to the search server 1 (S140). The subsequent processing is the same as in the second embodiment. It is the same as that of description.

  FIG. 13 shows a display window of a management screen for the table stored in the advertisement database 25. Here, it is assumed that the advertiser is looking at a picture displayed on the image display unit of the information processing apparatus remotely connected to the advertisement server 2. The advertiser can change the advertisement content to be displayed immediately and as intended by operating the display window of the management screen displayed in FIG.

  As shown in FIG. 13, the display window has an area 700 and an area 701. The area 700 is an area for setting whether to enable or disable P2. If P2 is validated, items related to the item that the client 3 is searching for can be preferentially displayed on the screen of the client 3. An area 701 is an area for setting the size of a value set in P2 when the character of the advertisement title partially matches the character of the search keyword. By setting the magnitude of the value set in P2 to a larger numerical value, an item related to the item that the client 3 is searching for can be displayed as the advertisement link 53 more preferentially. In the case of FIG. 11, the size of P2 is set to 1.

  As shown in FIG. 13, the tag of the advertisement C is provided with an area 67 for setting the size of P1. For example, an arbitrary natural number of 1 to 10 is input to the area 67. By setting P1 of the advertisement C to a large value, an item that the advertiser wants the client 3 to know can be set to be preferentially displayed on the screen of the client 3.

  In the above-described embodiment, the case where the search result displayed by the search server is displayed as a static web page has been described. However, the search result may be displayed as a dynamic web page. In this case, the advertisement link displayed in the search result may be displayed as a moving image. Further, even when the search screen is displayed as a still image as in the present embodiment, only the advertisement link may be displayed as a moving image.

  The specific configuration of the display window is arbitrary. You may set the magnitude | size of P1 and the magnitude | size of P2 by changing the position of the button which can be moved up and down along a rail. Moreover, the arrangement | positioning of an advertisement link should just be linked | related with the item 51, The specific arrangement | positioning location is arbitrary. The advertisement link may be arranged in the space next to the item 51 toward the screen, the advertisement link may be arranged in the space below the item 51, or the advertisement link is placed in the space next to and below the item 51. May be arranged. The configuration of the table stored in the advertisement database is arbitrary, and may be realized using a plurality of tables.

  Further, when two or more search keywords are input with a space between them, it may be determined whether or not the advertisement title partially matches each search keyword. When the character string of the advertisement title includes a character string of one of the search keywords, P2 may be set to be added. When the character string of the advertisement title includes character strings of both search keywords, a value of P2 × 2 may be set.
