The present invention relates to a method and system for constructing an online human network through content sharing, and more specifically, to a counterpart, a predetermined content which is held by the counterpart and is expected to be interesting to the counterpart in an e-mail or the like. The present invention relates to a method and system for constructing an online human network capable of further expanding the scope of an online human network by providing and establishing an acquaintance on the online human network through the medium.

Networks such as wired / wireless Internet or intranet are widely used as a means of communication, and based on this, the world wide web or e-mail (e-mail) enables social members to share information or gain knowledge. Means such as mail and messenger are actively used.

Recently, internet services are being actively used to build an on-line human network online by using a network such as the Internet. Human network refers to a virtual network of individuals who have become acquaintances through social life. An acquaintance is a range of others who have become more or less reliable as a result of sharing a certain amount of information, experiences, ideals, and community affiliation. Such acquaintances can be derived from a predetermined acquaintance. In general, social life is achieved by getting to know each other by kinship, schooling or delay, belonging to a specific organization, or working together through a company or team.

Recently, with the development and dissemination of networks such as the Internet, it is possible to form and maintain such acquaintances online, and to support the active construction of such a human network online among users, and to build a database of the constructed human network. You can use them to search for people who have the skills, careers, etc. you want, or you can establish a human network online with new acquaintances, and expand your human network based on that relationship. Many different service technologies have been proposed for sharing various files or information.

In such an online human network construction and management technology, it is important to secure the reliability of mutual relations among other things due to the characteristics of the network such as the Internet that an unspecified majority is accessible.

A process (B) of registering with 100 is performed. In this registration process, each user's ID, password, and personal information (job, gender, age, place of residence, work address, company name, school of origin, hobbies, etc.) may be inputted. Is stored in the user information database 12 (C) and managed. When each user subscribes to or registers a service (A, B), the human network building system 100 interlocks with the system and provides various user interfaces so that a user can easily use various functions provided by the system. A program may be downloaded to each user terminal to be executed on the terminal.

3 is a schematic diagram for explaining a process of forming a primary acquaintance relationship in the conventional human network building system 100. In order to form an online first-person relationship between users, the first user sends an invitation message to the fourth user's terminal 340 via the terminal 310, and the fourth user sends it at the terminal 340. Confirming, the process (D) of transmitting the acceptance message may be performed. The invitation message and the acceptance message may be in various forms such as an e-mail and a text message, and the human network construction system 100 recognizes that the invitation and acceptance process is performed, thereby establishing a primary acquaintance relationship between the two users. The acknowledgment information database 14 records the data in a predetermined data structure. In this case, the fourth user may be a user who has not been registered yet. In this case, a process of registering the user as a user in the system by transmitting and receiving data with the human network construction system 100 when sending an acceptance message for an invitation is added. It may be made of.

Hereinafter, with reference to the accompanying drawings will be described in more detail with respect to a preferred embodiment of the online human network building system and method according to the present invention.

5 is a schematic diagram illustrating one embodiment of an on-line human network building system 200 of the present invention. The online human network building system 200 of the embodiment includes a database 10, an application server 20, a web server 130, a message server 140, and a user management server 150. The database 10 may include a user database 12, an acquaintance information database 14, a user content database 116, and the like.

The online human network construction system 200 is connected to a plurality of user terminals 310, 320, 330, and 340 through a network 1 such as a wired / wireless internet or an intranet. For convenience, only four user terminals are illustrated, and the user terminals may be various fixed or mobile terminals, such as a laptop, a desktop, a PDA, and a PCS.

Users register with the human network construction system 200 online through their terminals 310, 320, 330, and 340. In this registration process, each user's ID, password, and personal information (occupation, gender, age, residence) , A work address, a company name, a school of origin, a hobby, etc.) may be input, and the information of each user is converted into a predetermined data structure, and stored and managed in the user database 12. When each user subscribes to or registers a service, the web server 130 interoperates with the human network construction system 200 online so that a user can easily use a predetermined application program that allows the user to use various functions provided by the system. You can also download it to your PC and run it on your device.

As described above, acquaintance relationships on the online human network formed between a plurality of users who have subscribed to the service through the network are stored and managed in the acquaintance relation database 14. The acquaintances recorded in the acquaintances database may be formed by the prior art invitation and acceptance process described above, but without the invitation and acceptance and the corresponding procedure, members of a specific portal site and members of a predetermined community provided on a web basis Or it may be an online acquaintance formed based on the qualifications of the members joined to a predetermined club.

6 illustrates a data structure in the acquaintance information database 14 formed through the above-described process. As illustrated, the acquaintance information database 14 defines a data structure (referred to as "relational data structure") that stores the IDs of each user in which a primary acquaintance relationship is formed with one-to-one correspondence. Can have Such a data structure has an advantage that data management is very easy since the user ID can be stored in correspondence with each user's ID sequentially according to the occurrence time of each event without changing the entire data structure whenever the invitation and acceptance process is performed. .                     

7 illustrates a graph data structure resulting from online human network formation. Here, the case where only four nodes (0, 1, 2, 3) exist for the sake of easy understanding. Through the relational data structure shown in FIG. 6, the graph data structure as shown in FIG. 7 is obtained. This data structure facilitates the location of each user on the entire human network. In this data structure, each node (0, 1, 2, 3) may be identified as corresponding to each user ID, and a link connecting each node (0, 1, 2, 3) is Represents a direct acquaintance (defined as a primary acquaintance, or a village) between users. Here, the user of node 0 and the users of nodes 1 and 3 are in a primary acquaintance (1st village), respectively, and the user of node 0 and a user of node 2 are in a secondary acquaintance (2nd village).

The data structure in the acquaintance relational database 14 illustrated on the right side of FIG. 7 is a data structure reflecting the human network represented by the graph diagram on the left side. On the left side, node 0 is connected to nodes 1 and 3, so that data 1 and 3 correspond to data 0 in the data structure on the right. Further, on the left side, node 1 is connected to nodes 0, 2 and 3, so that data 0, 2 and 3 correspond to data 1 on the data structure. Hereinafter, since it can be inferred through the above description, further description will be omitted. In addition to the contents exemplified above, it is possible to display an online acquaintance relationship using various data structures in the acquaintance relation database 14.

8 is a schematic diagram for explaining a process of searching for a human network in an on-line human network building system according to the present invention. In the case where the online human network is formed as shown in FIG. 8, the first user (a) has a desired condition (eg, a specific condition) among nodes in a predetermined relationship (eg, second generation) with him. In the case of looking for a node satisfying a job, a school of origin, etc., the range of the search performed by the search algorithm execution module 25 is as indicated by a black circle in FIG. In such an online human network construction system, as many subscribers as possible are connected to a network like a network, a wider range of retrieval is possible, and thus the use range of a human network can be expanded.

9 illustrates a data structure in the user information database 12. As illustrated, in the user information database 12, user information such as name, age, occupation, and gender of the user is stored in correspondence with each user ID (Userid1, 2, 3 ....).

10 illustrates a data structure of user content database 116. The user content database 116 is provided with storage spaces assigned to each user so that only the assigned user can record, view, update, and delete their contents. Such storage spaces are defined as a user content storage area R. FIG. In the user content storage area R, a user registration area I for identifying to which user the area is assigned, content content C stored by the user, and an access authority registration area for the content. (S) may be provided. In the access right registration area C, an ID of a user who is allowed to access the content among users other than the user corresponding to the corresponding user content storage area R may be stored. For example, it can be seen that among the contents stored in the content storage area of the first user of FIG. 10, the content 1-1 is granted access rights to the fourth user and the thirtieth user. It is possible for a user to register such other user's access rights for each content.

FIG. 11 illustrates a user terminal screen 400 when a user drives an application program installed in his terminal to record, view, update, and delete predetermined content in the user content storage area R. As shown in FIG. In the illustrated screen, a user runs an application program, transmits and receives data to and from the web server 130 of FIG. 5, and records the content in the user content database 116 in the database 10 assigned to the user. If necessary, the user may drive the application program to back up the corresponding content to his terminal.

12 is a flowchart illustrating an embodiment of a human network establishment method using the online human network establishment system of the present invention. As shown, first, a user accesses a system via a network and performs a user registration procedure through a screen provided by the web server 130 of FIG. 5, wherein the application server 20 performs a user information database 12. In step S10, the user information is recorded.

In this way, the user who subscribes to the service records his or her content in the user content storage area (R in FIG. 10) assigned to the user (S20). In this case, the user may use an application program installed in his terminal and providing a user interface screen as illustrated in FIG. 11.

In addition, the user transmits a message for establishing an acquaintance by allowing the receiver to access the specific content of his / her content to the receiver's terminal through the message server 140 of FIG. 5 described above (S30).

After the receiver receives the message, if the user agrees to the access right setting (S40), the receiver checks whether the receiver is a service subscriber (S50). If the receiver is not a service subscriber, the web server 130 provides a subscription screen to the receiver to proceed with the subscription procedure (S60).

When the subscription is completed, the user management server 150 of FIG. 5 records in the user content database 116 of FIG. 5 that the access right of the receiver is set to the corresponding content owned by the user who sent the message. (S70). Recording of data may be performed in the format shown in FIG. 10 for the user content storage area R in the user content database 116.

In addition, the application server 20 of FIG. 5 records in the acquaintance relational database 14 in the format illustrated in FIG. 6 that an acquaintance relationship is formed between the user who sent the message and the receiver (S80). This process may be omitted if only the access authority is set for the content and if the friend relationship is not desired.

In this way, the recipient whose access authority is registered can view the corresponding content through an application program installed in his terminal (S90).

Figure 13 shows another embodiment of a method for establishing a human network using the system for constructing an online human network of the present invention.

The difference from the embodiment of FIG. 12 is that when the receiver applies for temporary reading of the corresponding content (S120), the temporary receiving right is granted to the recipient. As shown, by downloading the VIEWER program to the terminal of the receiver (S125), it is possible to allow temporary viewing of the corresponding content through the VIEWER (S130). Here, the VIEWER may be a program of various types, but does not have all the functions of the application program of FIG. 11 described above, and accesses the user content database through at least the web server 130 to read only the corresponding content. A program module with only certain functions to be sufficient would be sufficient. For temporary viewing, the number of times or the time may be set to limit the continuous unauthorized viewing of the receiver.

In this way, by allowing the recipient to temporarily view the contents of the content, the recipient's interest can be further heightened, and the establishment of an acquaintance with the user and the subscription to the service system can be facilitated.

In another variant, if the receiver is a person who has already subscribed to the service, since the application program as shown in FIG. 11 may already be installed in the terminal of the receiver, the temporary access right through the user management server 150 of FIG. Is recorded in the user content storage area of the corresponding content. At this time, the user management server 150 may automatically delete the temporary access authority setting when the reading of the designated number of times or the reading for a predetermined viewing allowance period is finished.

14 illustrates one form of a message for setting access rights. The message 600 may be provided in various forms such as an electronic mail and a messenger. The recipient can send his acceptance intention to the human network building system 200 online by clicking the accept button 610 attached to the message. The system 200 may recognize the signal transmitted by clicking the accept button, and as described above, register the access right for the corresponding content and / or set up registration of the acquaintance relationship.

On the other hand, if the receiver does not want to view, the reject button 630 illustrated in FIG. 14 may be clicked to transmit the rejection intention to the system.

If the receiver wants to temporarily view the contents of the corresponding content, as shown in FIG. 14, the temporary view button 620 is clicked on to download the VIEWER or by using an application program already installed. It is possible to temporarily view the content.

15 illustrates another form of a message for setting access rights. In this case, the content viewing screen 730 of the application program shown in FIG. 11 is extracted and transmitted to the receiver without the need to download or use a VIEW or the like. The content of the extracted content as described above is defined as a snapshot. 16 illustrates another form of a message for setting access rights. In this case, a partial content 830 of the attached file is taken as a snapshot of the content.

Such a message can be created by the user through one screen of the user interface provided by the application program. At this time, in the application program, options for allowing the user to easily select the buttons of the various functions and attach them to a message or to format the snapshot may be provided to the user.                     

If necessary, when the user updates the corresponding content managed by the user as shown in the message of FIG. 14, the receiver does not need to open and check the corresponding content of the user, and checks whether the update is automatically performed. A notifier server (not shown) may be further provided in the system 200 of FIG. 5 to inform the recipient of an update.

Some or all of the technical idea of the present invention can be implemented in various forms such as hardware, software, and a recording medium recording the same. Although the above has been illustrated and described with reference to the preferred embodiments of the present invention, the present invention is not limited to the above-described specific embodiments, and the present invention belongs to the present invention without departing from the gist of the present invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such changes are within the scope of the appended claims.

By utilizing the method and system for constructing an online human network of the present invention, it is possible to activate the formation of an online acquaintance through the provision of predetermined content that the other party is expected to be interested in.

In addition, by utilizing the function of automatically notifying the content change of the content mediated by the acquaintance of the present invention, the other party does not need to continuously monitor the content change of the content, it is very convenient to share content It is possible to jointly use.                     

Furthermore, according to the present invention, even if the other party who is not yet able to access the specific content of the content, it is possible to feel more interesting through an invitation message containing a snapshot of the content, so that the online acquaintance It can further promote the formation of relationships.
