Abstract

PROBLEM TO BE SOLVED: To provide a link diffusion system for effectively transmitting and diffusing a URL link related to a membership service in a Web site which provides the service, within a community.SOLUTION: The link diffusion system includes a service provision server for providing a membership service, an information transmission server for providing an information transmission service and client terminals. The service provision server has a membership DB for holding information for each member showing whether he/she is a paid member, and each client terminal has a service use application and an information transmission client application. The service use application submits an input comment when a paid member uses the membership service, and embeds a URL link in the comment. On the other hand, it provides the membership service under limited use conditions to an unpaid member when he/she selects the URL link embedded in the comment, and makes him/her newly input and submit a comment in which the URL link is embedded when he/she finishes the use.

Description

  The present invention relates to information transmission technology, and more particularly to a technology effective when applied to a link diffusion system that transmits and spreads information specified by a URL (Uniform Resource Locator) link.

  In recent years, with the development of information communication technology, it has become possible for individuals and companies to transmit various types of information to others. As a mechanism for that, for example, in addition to a mailing list by e-mail, a homepage on a website, so-called blog (including mini-blog, micro-blog, etc.) services and various SNS (Social Networking Service) services There are various types.

  Information transmitted using these mechanisms includes information expressed in the form of links to URLs of other websites in addition to normal text information and image information (hereinafter referred to as “URL links”). There are many cases that may be described). Also, the information specified by the URL link is, for example, a Web page (for example, displayed on a so-called site map) that is relatively easy to access directly on the target Web site without using the URL link. In addition to a link to a Web page, etc., there are some that are difficult to reach the corresponding information unless accessed by the URL link.

  For example, in a service that stores moving images, photos, images, etc. on a storage service based on a cloud computing environment and allows these to be viewed, a URL link consisting of a URL including information specifying the target moving image as a parameter is transmitted. Thus, it is possible to identify a target moving image from among a large number of moving images and transmit the information. Also, in a service that displays map information around a specified position, place, spot, etc., a URL link made up of a URL that includes position information consisting of latitude and longitude of the target position, place, etc. as a parameter is transmitted. Thus, it is possible to transmit map information around the position.

  As a technique related to the above, for example, in Japanese Patent Application Laid-Open No. 2001-188734 (Patent Document 1), a WWW server accesses a position coordinate database, a content database, and a user database according to a search condition from a user terminal. Acquires location information (location name, location coordinates, address, telephone number, postal code, additional information describing the location) for a plurality of locations and displays them on a web page, and sends an e-mail according to instructions from the user terminal Create and add location information for multiple locations acquired from the database to the e-mail and send it to improve the convenience of location information, such as obtaining more detailed information from the attached location information The technology is described.

  On the other hand, recently, due to the spread of SNS services, etc., the information transmission destination is not only widely transmitted to a large number of unspecified users, but also related to the specific community to which the user belongs, the target information, or the target In many cases, the information is transmitted to a certain range of users such as users who are interested in the information. In addition, when a user who has received information is judged to be useful information, by retransmitting the information, information can be efficiently diffused and penetrated to effective communication destinations. There are many cases to go.

  As a technology related to the above, for example, in Japanese Patent Application Laid-Open No. 2011-76449 (Patent Document 2), an information mediation server that provides a user with product information related to a product or a service in order to receive a reward for achievement by an affiliate, By receiving the destination and keyword registration from the terminal, sending the keyword to the information providing server, receiving the product information based on the keyword from the information providing server, and sending the product information and user information to the destination By simply registering keywords related to products that the user is interested in, the product information can be automatically distributed to users such as users who acquaint the user and acquaintances of the user. A technique that can provide information efficiently is described.

JP 2001-188734 A JP 2011-76449 A

  By applying a mechanism like the above prior art, it is possible to transmit and diffuse information specified by a URL as a URL link between communities. However, in the URL link transmission method as in the mechanism of the prior art, for example, the service provided on the linked website is a membership service, and a paid member is required to receive provision of a predetermined service. In cases where it is necessary (for example, paid navigation services on mobile devices that use the target map information), users other than paid members can transmit information by the target service, or target information based on that information. I cannot receive service.

  In this case, it is unlikely that the target information will be retransmitted and spread from the user, and the transmission of information in this portion will stop there. Also, even when viewed from the service provider side, the user who received the URL link is not simply a paid member, so that the information transmitted by the target service specified by the URL or Simply saying that it is impossible to receive provision of a target service based on information will lead to a missed opportunity to incorporate these users as paid members of the service.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a link spreading system that effectively transmits and spreads URL links related to services on websites that provide membership services between communities. The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  Of the inventions disclosed in this application, the outline of typical ones will be briefly described as follows.

  In the link diffusion system according to the representative embodiment of the present invention, a URL link related to the membership service on a website providing the membership service is commented on a push type by a user to a predetermined group to which the user belongs. In the information transmission service that can post a message, the link diffusion system that embeds and notifies the comment in the comment has the following characteristics.

  A service providing server connected to a network for providing the membership service; an information transmitting server for providing the information transmitting service; and a client terminal which is an information processing terminal possessed by the user.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

[Overview]
In the link diffusion system according to an embodiment of the present invention, the URL link related to the service on the website providing the membership system belongs to, for example, an e-mail mailing list service or various SNS services. In a mechanism for transmitting information to a certain group or community (hereinafter, sometimes simply referred to as “community”) in a push manner (hereinafter, simply referred to as “SNS service” unless otherwise specified). It is a system that can be embedded and transmitted in messages.

  Here, the member who can embed information related to the target service in the message as a URL link and can be transmitted first is a member who is permitted to use the function of transmitting information by the URL link in the service. In other words, in this service, it is assumed that such functions can be used only by some members such as paid members (hereinafter, such members are collectively referred to as “paid members”). And other members and non-members may be described as “non-paid members”). In the present embodiment, even a paid member in the target service, for example, if the option for the function is not contracted, it is not a paid member, and conversely, a free member has also obtained a predetermined number of points, etc. If the use of the function is permitted, it shall be treated as a paid member.

  If a user who has received a URL link sent by a paying member embedded in a message using the SNS service is a paying member of the target service, the user accesses the target website based on the URL link, and the target It is possible to receive information transmitted by a service or to receive a target service based on the information.

  On the other hand, if the user who received the URL link is a non-paid member, the user accesses the target website based on the URL link, and the information by the target service under a predetermined limited use condition. Or receive provision of the target service based on the information. This predetermined limitation includes not allowing a function that is permitted only to paying members and that embeds information related to the target service in a message as a URL link and transmits it as needed.

  In addition, users who are non-paid members receive information regarding the use of the target service when they receive information from the target service under limited use conditions or complete the use of the target service based on the information. Etc., it is forced to send a message in which the target URL link is embedded. In other words, only when the use of the target service under the limited use conditions is completed, it is permitted to send a message in which information related to the target service is embedded as a URL link, like a paying member. Moreover, instead of permitting the use of the target service under such limited usage conditions by non-paid members indefinitely, only a paid member is eligible after the expiration date is set for the URL link. It is assumed that information can be transmitted by the target service specified by the URL link or provided by the target service based on the information.

  As a result, a URL link (including information specifying information transmitted by the target service or information used when using the target service) related to the target service on the website that provides the membership service is included in the SNS service. Makes it possible to communicate and spread effectively between communities. In addition, by making the target service available to non-paid members on a trial basis with a certain limitation, it is possible to give an opportunity to guide paid members as part of marketing.

  In the present embodiment, as a specific example, as a Web site that provides a membership service, map information is provided to a user, and further, position information by GPS (Global Positioning System) or the like is provided to a mobile terminal or the like. A description will be given of a site that provides a navigation function of a route to a destination based on map information as a service. Further, as an SNS service, a case will be described as an example in which a service such as a so-called miniblog, which can push notifications to other users in a community by posting a short comment.

  Here, the paying member of the navigation service uses the navigation function on the mobile terminal and accesses the navigation service website including the location information of the current position on the map by a simple procedure by cooperating with the SNS service. A service for posting a comment embedded with a URL link to the SNS service can be used.

  On the other hand, the non-paid member accesses the navigation service website by selecting the URL link included in the comment on the SNS service on the mobile terminal, and selects the point specified by the position information included in the URL link. A navigation function as a destination can be used. When the user reaches the destination and completes the use of the navigation service, a comment in which the target URL link (that is, the URL link to the navigation service including the location information of the destination) is embedded is provided in the same manner as the paying member. A service for posting to the SNS service can be used.

[System configuration]
FIG. 1 is a diagram showing an outline of a configuration example of a link spreading system according to an embodiment of the present invention. The link spreading system 1 includes a service providing server 10 that is a Web server system that provides a membership-based service (providing map information and a navigation service in this embodiment) to a user, and a server system that provides an SNS service. The SNS server 20 is connected to a network 40 such as the Internet. In addition, a user client terminal 30 is connected to the network 40 and has a configuration capable of communicating with the service providing server 10 and the SNS server 20. In the present embodiment, the client terminal 30 is a portable information processing terminal such as a mobile phone, a smart phone, a tablet terminal, or a laptop computer, and the current position of the GPS or the like used when using a navigation service is used. It has a positioning function.

  The service providing server 10 has a service providing application 11 that is an application program that runs on a web server program (not shown) and provides a navigation service to the user via the client terminal 30. In addition, the member DB 12 which is a database that holds information of members (paid members, free members) registered as users who can use the navigation service, and embedded in comments posted by pay members to the SNS service. And a link management DB 13 which is a database for managing URL link information for the target service.

  The member DB 12, for example, for each member, service information such as information such as user ID and profile, classification of paid member / free member (if a free member is provided), presence / absence of options for each service function in the case of a paid member, etc. Data related to items such as are retained. For example, for each URL link embedded by a paying member in a comment, the link management DB 13 relates to items such as URL information, the date and time when the URL link was created, the created member, and the validity / invalidity flag of the target URL link. Retain data.

  The SNS server 20 operates on, for example, a Web server program (not shown), accepts posting of a short comment from a user via the client terminal 30, and is a user's client terminal capable of viewing the posted comment 30 has an SNS server application 21 which is an application program that provides an SNS service such as displaying on the network 30. Moreover, it has user DB22 which is a database holding the information of the user registered as a user who can use SNS service, and comment management DB23 which is a database holding the content of the comment posted by the user.

  The user DB 22 holds, for example, data relating to items such as information such as a user ID and a profile and information relating to a community to which the user DB 22 belongs. For example, for each posted comment, the comment management DB 23 stores data relating to items such as an ID to be identified, a comment text, a user who has posted, and a posting date.

  The client terminal 30 is, for example, a service use application 31, which is an application program for using the navigation service provided by the service providing server 10 or the SNS service provided by the SNS server 20, respectively. And an SNS client application 32. These applications may be able to run independently, or may be web applications that run on a web browser (not shown).

  The user uses the service use application 31 in accordance with the use conditions such as a paying member and a free member, and in cooperation with the service providing application 11 of the service providing server 10, for example, browsing map information around the current position. And a navigation service to the destination. Further, by using the SNS client application 32, it is possible to use, for example, a comment posting or posted comment viewing service in cooperation with the SNS server application 21 of the SNS server 20. The service use application 31 directly cooperates with the SNS client application 32 or the SNS server application 21 of the SNS server 20 to provide information related to the target service (in this embodiment, including service location information of the current position). The URL link to the server 10) can be posted in a comment.

[Link diffusion]
FIG. 2 is a diagram for explaining the concept of URL link diffusion in the present embodiment. First, User A who is a paying member uses the URL of the information related to the target service as a function permitted only to the paying member when using the target service or when the use of the target service is completed. Post comments embedded as links. For example, in the present embodiment, the current position on the map (for example, a restaurant) when user A who is a paid member uses a navigation service to pass a spot on the route or arrives at a destination. Post recommended comments and comments about the project as needed. At this time, a URL specifying the current position on the map can be embedded as a URL link. For convenience of explanation, it is assumed that all users other than user A in the figure are non-paid members.

  The comment with the URL link posted by the user A is pushed to the members of the community to which the user A belongs (in the example of FIG. 2, the users B and C surrounded by the dotted line frame with the user A). A user who is a non-paid member in the community can use the target service free of charge under limited use conditions by browsing the posted comments and selecting a URL link. When the use of the target service is completed, a user who is a non-paid member can post an impression as a comment. At this time, the target URL link can be embedded in the comment.

  For example, in this embodiment, the user B or C who is a non-paid member selects the URL link in the comment posted by the user A, so that the position (restaurant) specified by the URL link is the purpose. You can use a free navigation service on the ground. At this time, users B and C cannot use the service of posting a comment embedded with a URL link that specifies map information of the current position at an arbitrary point, like user A who is a paid member. . On the other hand, when the destination (restaurant) is reached, the impression about the destination can be posted by embedding the target URL link (which specifies the destination).

  Similarly, comments with URL links posted by users B and C are members of the community to which users B and C belong separately from user A (in the example of FIG. The users D, E, F, and the users C, G, H, I) surrounded by dotted frames are pushed to the user, and the same processing as described above is performed, so that URL links are sequentially provided. It spreads. Also, comments with URL links posted by users B and C are also pushed to users A (and users B and C) belonging to the same community, thereby information (restaurants) transmitted via URL links. Feedback) and sharing experiences.

  In this way, by selecting the URL link embedded in the comment by the paying member, while allowing the non-paying member to use the target service for free, the target service is free when the use of the target service is completed. By posting a comment in which the URL link is embedded, the URL link can be effectively diffused among the communities. In addition, by allowing the non-paid member to use the target service for free under limited use conditions, it is possible to provide an opportunity to try the target service and induce the user to become a paying member.

  On the other hand, as described above, in the present embodiment, an expiration date is set for the URL link, and after this, only the paying member transmits information by the target service specified by the target URL link, or It shall be possible to receive provision of target services based on information. This makes it possible for non-paid members to use the target service even if they become paid members (for example, “I want to go to this restaurant commented by this person but I ca n’t go there. If you want to go there, you can motivate them to become paid members.

  FIG. 3 is a diagram for explaining the concept of the expiration date of the URL link in the present embodiment. FIG. 3 shows the timing at which each user who is a non-paid member browses a comment and selects a URL link after user A posts a comment with a URL link from top to bottom in time series. Yes. In addition, the dotted line in the figure indicates the expiration date of the URL link.

  As shown in the figure, the timing of browsing the comment and selecting the URL link may be different among the members in the community that are notified of the posted comment. When the timing at which the URL link is selected is within the expiration date of the URL link, as described above, a comment in which the URL link is further embedded can be posted using the target service free of charge. On the other hand, if the timing at which the URL link is selected is after the expiration date, for example, a message that guides the user to become a paying member may be displayed so that the use of the target service is not permitted. . In this case, the URL link is not spread after that.

[Processing flow (Comment posting with URL link)]
FIG. 4 is a flowchart showing an example of the flow of processing when a paying member posts a comment with a URL link. FIG. 5 is a diagram showing an example of a screen on the client terminal 30 when a paying member posts a comment with a URL link.

  In FIG. 4, first, the paying member activates the service use application 31 for using the target service on the client terminal 30 (S01). After that, by inputting the user ID, password, etc. on the service use application 31, a request for the first login authentication is made (S02). Here, in addition to authentication with respect to the service providing server 10 that provides the target service, a request for authentication with respect to the SNS server 20 that provides the SNS service is also made. The service use application 31 may individually request login authentication for both of them, or may request login authentication for both by a single input of a user ID or the like.

  When the service providing application 11 of the service providing server 10 performs authentication processing with reference to the member DB 12 (S03), and when the SNS server application 21 of the SNS server 20 performs authentication processing with reference to the user DB 22 (S04). In the client terminal 30, the service use application 31 provides the target service to the paying member in cooperation with the service providing application 11 of the service providing server 10 (S05, S06). For example, in the present embodiment, as shown in the screen example on the left side of FIG. 5, the paying member uses the navigation service on the client terminal 30.

  The paying member can post a comment for transmitting information related to the target service to the SNS service in cooperation with the SNS service at any time while using the target service. Specifically, during the use of the target service, according to an instruction from a paying member, the service use application 31 cooperates with the service providing server 10 as necessary to specify a URL for specifying information related to the target service. Information is acquired (S07), and then, in cooperation with the SNS client application 32, a comment in which the acquired URL is embedded as a URL link is posted (S08).

  For example, in the present embodiment, a paid member presses a comment button at the lower right of the screen while using a navigation service as shown in the left screen example of FIG. As shown, a screen for posting a comment in cooperation with the SNS service is displayed. At this time, a URL specifying the current position on the map in the navigation service is automatically embedded in the comment as a URL link. The paying member can further add a comment on the current position (restaurant etc.) and post it as a comment.

  When a paying member posts a comment with a URL link on the client terminal 30, the SNS server application 21 of the SNS server 20 registers the content of the comment in the comment management DB 23 (S09). Thereby, the content of the comment is pushed to the members of the community to which the paying member belongs on the SNS service. As shown in the screen example on the right side of FIG. 5, the community member browses the content of the comment (portion surrounded by a dotted frame in the figure) using the SNS client application 32 on the client terminal 30. be able to.

  The contents of the comments posted in steps S08 and S09 are registered in the SNS server 20, and the service using application 31 of the client terminal 30 notifies the service providing server 10 of the URL link information embedded in the comments (S10). . The service providing application 11 of the service providing server 10 registers the received URL link information in the link management DB 13. Here, for example, the date and time when the URL link was created, information about the created paid member, and the like are registered. By using this information, as described later, it can be determined whether or not the target URL link is within the expiration date.

  Through the process as described above, a comment with a URL link in which a URL link specifying information related to the target service is embedded is posted to the SNS service by the paying member.

[Processing flow (view comments and use services)]
6 and 7 are flowcharts showing an example of the flow of processing when using the target service from a comment with a URL link posted by the user. FIG. 8 is a diagram showing an example of a screen on the client terminal when the target service is used from a comment with a URL link posted by the user. In FIG. 6, first, a user (a paying member or a non-paying member of the target service) activates an SNS client application 32 for browsing posted comments on the client terminal 30 (S11). After that, by inputting a user ID, a password, etc. on the SNS client application 32, a request for login authentication to the SNS service is made (S12).

  When the SNS server application 21 of the SNS server 20 performs an authentication process with reference to the user DB 22 (S13), it extracts a comment that can be viewed by the target user from the comment management DB 23 (S14), and extracts it from the client terminal 30. It is displayed on the SNS client application 32 above. The user browses comments (including comments with URL links) displayed on the SNS client application 32 (S15).

  When the user selects a URL link embedded in a comment with a URL link as shown in the screen example on the left side of FIG. 8 (S16), the SNS client application 32 is a Web site specified by the URL link. A request is transmitted to the service providing server 10. The service providing application 11 of the service providing server 10 that has received the request instructs the client terminal 30 to start the service using application 31 (S17), and the service using application 31 is started on the client terminal 30 based on the instruction. (S18).

  For example, when the user is a non-member and does not yet have the service use application 31 on the client terminal 30, the service use application 31 is downloaded from the service providing server 10 or a predetermined download site. A message for instructing to do so may be displayed on the client terminal 30.

  When the service use application 31 is activated, the user requests login authentication to the target service by inputting a user ID, a password, and the like (S19), and the service provision application 11 of the service provision server 10 refers to the member DB 12. Then, an authentication process is performed (S20). If the user is a non-member and does not have a user ID for the target service (service providing server 10), the service providing server 10 may use the service providing application 31 instead of the login authentication process (S19, S20). An access request related to free service processing may be made to the service providing application 11.

  Thereafter, the service providing application 11 of the service providing server 10 refers to the member DB 12 and determines whether or not the user is a paying member (S21). If the member is a paying member, a notification permitting the use of the target service is transmitted to the client terminal 30 together with the authentication result of step S20. Upon receiving this notification, in the client terminal 30, the service use application 31 provides the target service to the paying member in cooperation with the service providing application 11 of the service providing server 10 (S22, S23).

  The service content here relates to information specified by the URL link selected by the user (paid member) in step S16. For example, in the present embodiment, the service content is shown in the central screen example of FIG. As described above, the navigation service uses the position on the map specified by the URL link as the destination. Paid members can use such services at any time without limitation. Further, while using the navigation service, a comment with a URL link based on the current position can be newly posted at any time by the process as shown in FIG.

  On the other hand, if the user is a non-paid member in step S21, the process proceeds to the processing flow of FIG. 7, and the service providing application 11 of the service providing server 10 refers to the link management DB 13 and selects the selected URL link. It is determined whether or not is valid (whether it is within the expiration date) (S24).

  For example, whether the URL link is valid is determined by referring to the link management DB 13 to acquire information on the creation date and time of the URL link, and the time when the URL link is selected by the user (or the current time). The comparison can be made depending on whether or not the difference exceeds a predetermined period (for example, one week). Alternatively, in the service providing server 10, a batch program that is periodically activated or the like is invalidated for a case where the difference between the creation date and time of each URL link in the link management DB 13 and the selection time exceeds a predetermined period. By setting a flag, the determination content in step S24 may be simplified to determination of a valid / invalid flag.

  In step S24, when the target URL link is invalid (the expiration date has passed), the service providing application 11 of the service providing server 10 notifies the client terminal 30 to that effect. Upon receiving the notification, the service use application 31 of the client terminal 30 displays a message for informing that the target URL link is invalid, and does not permit the use of the service (S25). At this time, a message for guiding the user to become a paying member may be displayed together. Here, when a user who is a non-paid member performs a procedure / process for becoming a paid member, the use of the target service as a paid member may be permitted in steps S22 and S23.

  If the target URL link is valid (within the expiration date) in step S24, a notification permitting limited use of the target service is transmitted to the client terminal 30 together with the authentication result in step S20. In response to this notification, in the client terminal 30, the service use application 31 cooperates with the service provision application 11 of the service provision server 10 to provide the target service for free to the non-paid member under limited use conditions. (S26, S27).

  The service content here relates to information specified by the URL link selected by the user (non-paid member) in step S16. For example, in the present embodiment, the service content is shown in the central screen example of FIG. As shown, the navigation service has a location on a map specified by a URL link as a destination. Non-paid members can use such services only if the URL link is within the expiration date. In addition, a function for newly posting a comment with a URL link based on the current position, which is permitted by a paying member, while using the navigation service cannot be used.

  When the user (non-paid member) completes the use of the target service under the limited use conditions (S28), the service use application 31 of the client terminal 30 is selected in step S16 in cooperation with the SNS client application 32. A comment in which the URL link is embedded is posted (S29).
