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

1 is a schematic diagram illustrating an embodiment of a human network based knowledge sharing system 100 of the present invention. The knowledge sharing system 100 of the embodiment includes a database 10 and an application server 20. In the database 10, a user database 12, an acquaintance information database 14, a query database 16, and the like may be provided.

The human network-based knowledge sharing system 100 connects to a plurality of user terminals 310, 320, 330, and 340 through a network 200 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 to the human network-based knowledge sharing system 100 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. Upon joining or registering a service of each user, the human network-based knowledge sharing system 100 interoperates with a human network search system online so that a user can easily use a predetermined 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.

The online human network-based knowledge sharing system of the present invention is based on an acquaintance on an online human network formed between a plurality of users who have subscribed to a service through a network. The acquaintance relation on the online human network is an acquaintance relation database. 14 is stored.

As a method of forming an acquaintance on the online human network, for example, the method described in Patent Application No. 10-2004-82761 filed separately by the applicant can be used. Referring to FIG. 1, a process of forming an acquaintance relationship for the purpose of example is described. In order to form an online acquaintance relationship between users, the first user sends an invitation message through the terminal 310 to the terminal of the second user. In step 330, the second user confirms this in the terminal 330, so that 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-based knowledge sharing system 100 recognizes that the invitation and acceptance process is performed, and a primary acquaintance relationship is formed between the two users. Is recorded in the acquaintance information database 14 in a predetermined data structure. In this case, the second user may be a user who has not been registered yet. In this case, the second user may be a user in the system through data transmission and reception with the human network-based knowledge sharing system 100 when the second user accepts an invitation message. You can also have the process of enrolling.

Alternatively, there may be an online acquaintance formed based on the qualifications of a member of a specific portal site, a member of a predetermined community, or a member of a predetermined club, provided on a web basis, without such an invitation and acceptance and a corresponding procedure.

2 illustrates a data structure in the acquaintance information database 14 formed through the above-described process. As illustrated, the acquaintance information database 14 has a data structure (defining such a data structure as a relational data structure) that stores the IDs of the respective users who have formed a primary acquaintance with each other in a one-to-one correspondence. Can be. 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. .

3 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. 2, a graph data structure as shown in Fig. 3 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 is a data structure reflecting the human network shown 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. In addition, since the node 1 is connected to the nodes 0, 2, and 3 examples on the left side, 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.

4 is a schematic diagram illustrating the operation of the online human network based knowledge sharing system of the present invention. In the case where the online human network is formed as shown in FIG. 4, when a question arises to the first user a, the first user a may identify the second user among the users who are primarily acquaintances with the user. b) in the form of messages that can be sent over the network. Regardless of the format of the message such as e-mail, messenger, and note. In this case, when the second user b does not have knowledge of the contents of the query, the second user b may transmit the information to the third user e. Similarly, if the third user does not have the corresponding knowledge, the third user may transmit sequentially to the fourth user j and the fifth user p. If the fifth user p has knowledge of the content of the query, the fifth user p prepares an answer and transmits it directly to the first user a (R1). Alternatively, the response message of the fifth user p may be delivered to the query creator sequentially (p-j-e-b-a) via the users on the reverse path of the query message delivery path.

Through this operation process, the first user a can more reliably obtain a reliable answer to his or her question by utilizing an already established online human network.

The server 20 may provide various functions to a user who wants to send an inquiry message by using a human network online. For example, in order to increase the reliability of an answer, it is possible to send a message to an acquaintance who shares a field of interest according to the category of the query in selecting a destination to which the query message is sent. That is, the server 20 may provide the interested party or personal information of the user whose acquaintance relation is set in the acquaintance information database 14 to the counterpart in the acquaintance relation set with reference to the user database 10. As a reference, a user who wants to send a query message can select an acquaintance most likely to answer the query correctly and transmit the query message. In addition, the server 20 selects the users with the highest number of answers, relays, and the like, and provides their IDs to the user who composes the query message, or sends a message to these users by relaying the server 20. It is also possible to let. In addition, the server 20 may provide a setting menu for allowing the user who made the query to limit the number of paths for the query to be transmitted on the human network online (for example, within the uncle and the uncle).

Or, if you don't limit the number of paths and only forward to each person corresponding to each node on each path, if you give the base point, it will spread out radially and consume many points. By providing the ability to press the STOP button, you can also provide a function to prevent further propagation of the query.

Fig. 5 illustrates the data structure in the query database 16 of the online human network based knowledge sharing system of the present invention, and Fig. 6 illustrates the data processing process. When the query message is created by the first user (a) (1), the application server 20 generates a query ID for identifying the generated query message and transmits it to the query database 16 provided in the database 10. Save it (2).

In addition, the application server 20 stores the ID of the second user b selected from among the users with whom the first user a is acquainted with the query ID (3), and stores the query message in the second user (b). (4). If the second user (b) does not have the knowledge, the second user (b) makes a transfer request to a third user (e) selected from his acquaintances (5). The application server 20 stores the ID of the third user e in correspondence with the query ID (6) and delivers the query message to the third user (e) (7). Through this process, the query ID (Question id1) and the ID of each user may be stored in a corresponding data structure as shown in FIG. 5. This data structure represents the delivery path on the human network of query messages. In the illustrated example, only the case in which the query message is delivered in a 1: 1 manner for convenience of description, but may be transmitted from one user to a plurality of users through a similar process. For example, in the form of broadcasting (broadcasting), all of their acquaintances can be sent to the query message.

However, by accumulating only a certain point for each node and increasing the probability of deriving a final answer to a node corresponding to a large number of selected acquaintances, if the final answer is delivered to the interrogator and satisfied, additional bonus points proportional to the satisfaction You can also get. In this case, the bonus points can be earned for all nodes that exist between the final responder and the queryer.

7 illustrates the format of a query message delivered in the knowledge sharing system of the present invention. When registering as a member, a program installed in a user's terminal may be used to create a query message in a predetermined format. For example, a receiver may be designated and a query content may be input as illustrated. For the designation of the recipient, it is possible to provide a list via the user's terminal so that he can choose among his acquaintances in the online human network. When the first user composes the query message A, it is transmitted to the designated second user b among the acquaintances to display the caller and the content of the query (B). The message transmitted as described above may be accompanied with various buttons for improving the convenience of the receiver's response. Various buttons, such as affirmative 410, negative 420, or forward 430 to one's acquaintance, may be provided, or may be configured in a questionnaire form such as multiple choice. Various tools may be provided by a program installed in the terminal of the query creator to freely configure the format of the query message. When the second user b who has received the message clicks the forward to his acquaintance 430 button, a list is provided to select from his acquaintances, and the application server recognizes it.

8 illustrates a preferred embodiment of the online human network based knowledge sharing method of the present invention. First, the construction process of the acquaintance information database constituting the online human network is shown (S100). User information is stored by the user's subscription (S10), and the first acquaintance is formed by the invitation / acknowledgement process between the users illustrated above (S15), and the server recognizes this and recognizes the first acquaintance relationship information between users. The data structure is stored in the acquaintance database (S20). Through this process, information about the human network is constructed online in the acquaintance information database.

When the first user composes and transmits a query message (S30), the application server generates a message ID, stores the message ID, and associates the ID of the first user who is the query creator (S35). The application server transmits the same to the second user selected from the acquaintances of the first user, and corresponds the ID of the second user to the message ID (S40). If the second user who has received the message possesses knowledge capable of answering the query (S50), the answer is written (S70), and if not, the second user who receives the message is transferred to the selected third user among the acquaintances of the second user. (S55).

This delivery process can be repeated sequentially on the online human network described above, and the k-th user (k is an integer of 2 or more) who has received the inquiry message can deliver the message to the k + 1 user of his acquaintances. If necessary, it is possible for the k-th user to respond, and at the same time, forward it to his / her acquaintances, or delete the message if he or she does not intend to reply or forward it.

The answer may be delivered directly to the query creator by referring to the user ID on the query message delivery path corresponding to the query ID.

9 illustrates the configuration of a reply message. The illustrated answer message P contains the content of the query and the content of the answer and, together with the answer author E-1 (e.g. user p), relates the answer author and the query author's online human network relationship (e.g. , 4th generation) and delivery path (eg, abejp) can be displayed to the query author. If necessary, you can build a first-person relationship with the answerer (E-2) to facilitate the construction of an online human network with people who have the information they need. In order to facilitate knowledge sharing on an online human network, users on the route may be required to pay certain incentives such as cyber money and mileage.

In addition, through the terminal of the query writer, it is possible to detect and display it on the terminal of the query writer at each application server so as to understand how the query message is transmitted on the online human network. To this end, it is also possible to visualize and display using a graph diagram as shown in FIG. 4, and may display only the number of villagers on the online human network of the user who has received the current message.

The application server 20 may extract a relay hub, a knowledge hub, and the like by analyzing a query message delivery and answer path on an online human network. In the analysis process, for example, in the on-line human network-based knowledge sharing system of the present invention, the responses of the users recognized by the server 20 from the terminals 310, 320, 330, 340 of the users who received the queries (Response or transfer) may be used by the server 20 to count each user, consider a user who has answered a lot as a knowledge hub, and a user who delivers a lot as a relay hub. Or, based on the query author's evaluation of the content of the answer (for example, grades can be entered for each satisfaction level such as A, B, C, etc.), the knowledge hub is selected through a method of quantifying the contribution of the answer maker individually. To give a predetermined incentive, or to reset the relationship with the answer creator (for example, to set up a hoodie relationship).

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.
