Title: System and method for providing social network service

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a social network service, and more particularly, to a system and method for providing a social network service that enable a user to create and practice life contents by himself/herself over a social network, and to share his/her life contents with other users, and facilitate bidirectional communication between a user and an advertiser to increase the efficiency and effect of an advertisement. 
     2. Description of the Related Art 
     Recently, ways of providing and using web contents has quickly changed. When the web contents has started being provided at first, a few professional providers have created and provided most of the contents and numerous ordinary users just has used the provided contents as used in typical media. 
     However, with the advent of Web 2.0 that emphasizes the participation and cooperation of users, general users has also participated in creating the contents and the creation/usage of the contents without a distinct classification between a producer and a user is recently accelerated on blogs or sharing sites. 
     Thus, user created contents are sharply increasing in importance in the whole web. Such user created contents are mainly found on blogs, micro blogs, web forums, picture or video sharing sites, etc. and in addition, many users creates contents by themselves through social network platforms. Due to an explosive increase in such user created contents, a technology to provide contents of a good quality to users through search or recommendation on a large amount of contents is needed. 
     People want to live successfully and happily. However, living so is very difficult. Some people set up goals at the begging of the year or when there is something desired, and put these into practice but some people do not. 
     Recently, most people are widely using inventive digital equipment such as a smart phone or a tablet PC and it is possible to process various tasks, e.g., to manage their schedules or check their emails by using such equipment. 
     Typical social network services just enable relation formation and information exchange. The amount of contents (information, materials, etc.) exchanged over the internet has remarkably increased as compared to that of contents exchanged through offline services in the past but there are some limitations in distribution of redundant contents, low quality of distributed contents, unproductive information utilization by a user who is a member of a social network, etc. 
     The current social network service is limited to relation formation, information exchange, etc. and focuses on commercial utilization based on the number of subscribers. Thus, there is a limit in performing functions of achieving comprehensive life goal and objective of a user participating in the social network service. 
     As such, the typical social network service has focused on distributing interest-oriented or simple information, in which process redundant distribution of similar contents, a decrease in quality of distributed contents, social side effect due to a strong addictive characteristic, and unproductive information utilization by a user who is a member of the social network are pointed out as limitations. 
     Paths to access customers increase due to an increase in advertising media and a development of in interactive media technology such as the internet enables real-time communication between a customer and a company. It is possible to see various kinds of advertising messages everywhere on/off line throughout 24 hours due to the diversity of such advertising media and the development of an information technology. 
     However, most customers avoid commercial advertisements and thus an advertiser does not obtain an effect according to the expenditure of an advertising cost. 
     In particular, since a typical online advertisement shows an advertisement suitable for web page contents which a user searches to obtain information, there is a limit in accurately matching the intention and interest of a user. In addition, since the user basically avoids commercial advertisements, the efficiency and effect of an advertisement are in doubt. Further, there is basically a limit in focusing only on a search activity among several daily activities of a user, setting up target audience, and providing an advertisement.

       FIG. 1  is a schematic diagram of a system for providing a social network service according to a first embodiment of the present invention. 
     Referring to  FIG. 1 , the system for providing a social network service according to a first embodiment of the present invention is connected to at least one subscriber terminal  100  over a network. The system includes a subscriber profile DB  321  that stores profile information including biography, goals, and activities of the subscriber; a social interchange field DB  322  that stores public profile information of the subscriber profile information; a catalyst DB  323  that stores at least one of a comment regarding the activity and ceremony information; and a control unit  310  that receives a goal in life and activities to achieve the goal from the subscriber terminal, creates or updates the social interchange field of the subscriber and provides at least one of an activity, social interchange field, a comment corresponding to the activity, and ceremony corresponding to a goal achieving process of another user depending on a selection of the subscriber terminal. 
     The control unit  310  includes a subscriber managing unit  311  that processes authentication of the subscriber terminal; a social interchange field control unit  312  that receives a goal in life and activities to achieve the goal from the subscriber terminal, and updates the social interchange field of the subscriber; and an information providing unit  313  that provides at least one of an activity, social interchange field, a comment corresponding to the activity, and ceremony corresponding to a goal achieving process of another user depending on a selection of the subscriber terminal. 
     The control unit  310  may function to remove negative elements from the mind of a user if necessary, may enable a user to set up a goal, may present mentor information to enable the user to plan a particular activity for achieving the goal, may analyze how close the user has reached to the goal if the user has input an activity which has been put into practice in daily life and may then provide ceremony. Detailed components that make up the control unit  310  and a DB unit  320  are functionally classified but may function as one unit if necessary. 
     Then, the operation of the system for providing a social network service will be described below in more detail. 
       FIG. 2  is an operational flow chart of the process of creating the social interchange field in a method of providing a social network service according to a first embodiment of the present invention, and  FIGS. 3 to 7  are exemplary views of screens according to a method of providing a social network service according to a first embodiment of the present invention. 
     A user and a subscriber have the same meaning, the user indicates a person before subscription, and the subscriber indicates a person after subscription. 
     Referring to  FIG. 2 , a user uses his/her terminal to connect to the control unit  310  functioning as a web server over a network. Since it is known that the user may see a web page provided by a given web server, through his/her terminal&#39;s screen if the user connects to the given web server by using his/her terminal  100 , a related detailed description is not provided. 
     Then, the subscriber managing unit  311  provides an initial screen as shown in  FIG. 3  and several variations on such a screen may be made. 
     Next, the subscription managing unit  311  receives an ID and a password from the terminal and performs an authentication procedure in step S 201 . 
     If the user does not have an ID or a password, the subscriber managing unit  311  performs a subscription procedure by receiving member information from the terminal  100 , creating subscriber profile, and storing input information. 
     Subsequently, the information providing unit  313  provides menu information in step S 203 . Such menu information may be always provided on various display screens. 
     Then, if a subscriber selects a menu for creating a social interchange field, the social interchange field control unit  312  receives a goal in life from the subscriber terminal  100 , creates a social interchange field for that subscriber, and stores the social interchange field in the social interchange field DB  322 , and such information is also stored in the subscriber profile DB  321 , in step S 205 . 
     In this case, the social interchange field control unit  312  makes detailed profile information including subscriber&#39;s life contents (dreams, how-to, intermediate objectives (IOs), activities) as needed, and activities functioning as the results of user&#39;s actual practice are input and updated to user profile and the social interchange field. The user profile includes dreams of a user being a member of a social network, how-to, IOs, and activity streams for achieving the dreams, and the same matters are also included in the social interchange field. Thus, it is possible to integrate the user profile and the social interchange field into one element and operate the integrated element. 
     The user being a member of the social network classifies actually performed activities based on life contents that he/she has made, according to a classification criterion. If the activities are made public, related updates are simultaneously performed on his/her user profile and the social interchange field, and if they are not made public, related updates are performed only on his/her user profile. 
     In addition, the social interchange field control unit  312  may provide and set ceremony information from the subscriber terminal  100  depending on a process for achieving a goal even if the goal itself is not been achieved yet. For example, if a desired period is three months and activities corresponding to one, two, and three months are input, each of first, second, third ceremonies may differ from one another. In some cases, it is also possible to provide ceremonies on a weekly basis. The ceremony is a behavior indicating celebration and may involve various actions. Ceremony information may be stored in the catalyst DB  323 . 
     If the subscriber selects a menu for inputting activities in step S 206 , the social interchange filed control unit  312  receives activities performed to achieve a goal, from the subscriber terminal  100 , and receives the kind of the activities in a tag function. In this case, the tag may be classified into various items such as life, education, assets, business, etc. and a user may personally input the items or may select them. 
     The social interchange field control unit  312  stores the received activities in the subscriber profile DB  321  and also stores in the social interchange filed DB  322  if the activities are for public use. In some cases, the social interchange field control unit  312  may be selectively stored in the subscriber profile DB  321  or the social interchange field DB  322 . 
     An update is performed to a screen as shown in  FIG. 4  or  FIG. 5  to provide it to the terminal  100  and an input is performed through a screen as shown in  FIG. 4 . An input activity is posted with tag information which is also stored in the social interchange field DB  322 .  FIG. 4  is a subscriber profile screen,  FIG. 5  is a social interchange field screen, a movement to each screen is made by using a menu, and such a menu selection may be performed in various ways. 
     It is possible to attach moving pictures, still pictures, etc. as needed to an activity and if a corresponding attached file is selected, the social interchange field control unit  312  reads and provides a corresponding file from the subscriber profile DB  321  or the social interchange field DB  322 . 
     If the subscriber terminal selects viewing all activities, the information providing unit  313  provides recent activities with reference to the social interchange field DB  322  and this type corresponds to a type that is obtained by expanding all activities of  FIG. 3  in step S 207 . In this case, recent ones of activities input by all users are displayed in order. That is, the top activity is the most recent activity. 
     In addition, if the subscriber terminal selects viewing all social interchange fields, the information providing unit  313  provides simple information regarding social interchange fields of all users with reference to the social interchange field DB  322 , in which case one recent activity is provided per social interchange field instep S 208 . A restriction on a screen display causes the simple information which indicates a subscriber&#39;s ID and a subscriber&#39;s goal. 
     If desired activities are selected from such activities in step S 209 , the information providing unit  313  provides a social interchange field of a selected activity owner in step S 210 . 
     An example of such a screen is provided in  FIG. 7  and while the subscriber views the goal or the activities in the social interchange field as shown in  FIG. 7 , he/she may input comments corresponding the activities in step S 214  depending on his/her selection in step S 211 . The information providing unit  313  receives the comments and stores them in the catalyst DB  323  in step S 215  if the comments are input. In this case, the comments function as catalyst and if comments are received from other users, subscribers may have a strong will to achieve his/her goal and have pleasure in performing activities due to encouragement from other users. In some cases, an operator may provide a separate benefit of such a comment. For example, it is possible to provide Dotory functioning as cyber money, free gifts and points. In addition, the social network catalyst may analyze user&#39;s activities in terms of accomplishment (how much life contents have been accomplished), fulfillment (how much life contents have been fulfilled), effort (how hard a user makes an effort to achieve life contents), and interaction (how deeply user&#39;s important experiences and wisdom will be shared with other users) and may feed the analyzed results back to a user. Accordingly, active social communication is facilitated among social network members, and it is possible to monitor and evaluate behaviors of members, and feed the results back so that each member achieves his/her life contents. 
     In addition, it is possible to make public profile as shown in  FIG. 6  and use comments or other functions as shown in  FIG. 7  as needed. 
     In addition, a user may select a share menu, use and vary a social interchange field of other users to create his/her social interchange field or life contents in step S 213 . 
     If the social interchange field is created in this way, the social interchange field control unit  312  stores it in the social interchange field DB  322  in step S 215 . 
     Also, the user may select some or all of his/her contents as public or private to protect his/her privacy. In this case, the information providing unit  313  provides information regarding public social interchange fields to users. 
     Referring back to  FIG. 5  or  FIG. 7 , the social interchange field includes public contents of users being social network members, and the users being the social network members may make active social communication between users in the social interchange field. In addition, the accomplishment, the fulfillment, the effort, and the interaction may be provided as evaluation items, in which case the accomplishment may be determined based on a period, the fulfillment may be determined based on the number of activities, and the effort and the interaction may be determined based on the number of comments that a user has provided to other users. Such matters may vary as needed. In addition, the information providing unit  313  indicates by arrows in profile information how much a user&#39;s goal has been achieved, which makes the user easy to know how much the user&#39;s goal has been achieved. 
     The process of selecting a menu may be performed through a screen any time as needed, and an input entry such as an activity and a comment is updated after input operations on the subscriber profile DB  321  and the social interchange field DB  322  and thus users may immediately view updated activities or comments. 
     Such a first embodiment may make several variations and among others, an embodiment integrated into an advertisement will be described.
