Figure 8 is an operation flowchart showing a method of providing a social network service based on user taste data according to an embodiment of the present invention.

Referring to FIG. 8, the method of providing a social network service based on user taste data according to an embodiment of the present invention may first group other users who have registered the second content in the content information (S810).

Next, a preset number of other users can be selected by applying a different probability of selection for each group (S820).

For example, other users who registered the second content in the content information are classified as the first group, other users who registered the brand of the second content in the content information are classified as the second group, and the type of product corresponding to the second content is classified in the content information. Other users registered with can be grouped into a third group. Thereafter, a preset number of other users can be selected by applying the highest probability that another user in the first group will be selected and applying the lowest probability that another user in the third group will be selected.

Through this, you can connect with other users who have registered the same content and communicate about the same tastes. In addition, new products that suit the user's taste can be found within the product brand, and the user can gradually expand the range of the user's taste by learning about products of a new brand that the user was not aware of. .

For another example, contents registered in the content information of the first user and contents registered in the content information of each other user may be compared and grouped according to the same number of registered contents. If only the second content is the same, it can be grouped into a first group. If the second content and one other type of content are the same, it can be grouped into a second group. If three or more types of content including the second content are the same, it can be grouped into a third group. Thereafter, a preset number of other users can be selected by applying the highest probability that another user in the third group will be selected and applying the lowest probability that another user in the first group will be selected.

This has the effect of connecting with other users with the same tastes and enabling more in-depth communication about common tastes.

As in the above examples, any means that can divide groups of different users can be used without limitation, and the means in the present invention are not limited to the above examples.

In an optional embodiment, the user information may include membership score and membership level.

Specifically, users can accumulate membership points through activities within the service, such as registering content information or exposing profiles to other users, and through this, a membership level can be assigned according to a preset membership score range.

At this time, in step S820, another user can be selected by applying an additional probability of a preset ratio according to the membership level of each user to the selection probability applied to each group. Through this, users with high membership levels who accumulate a lot of membership points through active activities can increase the probability of their profiles being exposed to other users.

Figure 9 is an operation flowchart showing a method of providing a social network service based on user taste data according to an embodiment of the present invention.

Referring to FIG. 9, the method of providing a social network service based on a user's taste data according to an embodiment of the present invention includes registering the taste data in the content information of the first user, and then registering the taste data in the content information of the first user. If the number of other users who have registered the third content as content information is more than a preset number, a notification asking whether to create a community for the third content may be transmitted to the first user terminal (S910).

Next, when the first user's selection input for creating the community is received from the first user terminal, a community for the third content can be created (S920).

As an optional embodiment, after step S250, a purchase link for the selected first content may be provided to the second user terminal.

At this time, options including external links for purchasing new products and internal links for purchasing used products can be provided.

Next, if the first community has been created, it can be confirmed whether the second user has joined the first community.

Next, if the second user is registered in the first community, a seller list including other users selling the first product may be provided to the second user terminal.

Next, a selection input for any one of other users included in the seller list may be received from the second user terminal.

Next, a third notification instructing the second user to purchase the first product may be transmitted to the third user terminal of the selected third user.

At this time, information may be provided so that the third user can determine whether the first product suits the taste of the second user.

For example, the second user's membership period for the first community and information on the activity details in the first community may be provided to the third user terminal.

Through this, the third user can directly determine whether the first product suits the taste of the second user. Additionally, if the membership period for the first community is short or activity in the first community is judged to be infrequent, the third user may be able to sell the product after sufficient conversation by exchanging messages with the second user about the first product. It can be induced to happen.

As an optional embodiment, after the step of checking whether the second user is registered with the first community, if the second user is not registered with the first community, the first community is connected to the second user terminal. It may include transmitting a fourth notification instructing to subscribe to.

As an optional embodiment, the membership score is accumulated for each of the preset first items, the user's membership level is divided according to the preset score range, and the points are allocated to each of the preset second items. A predetermined number of points can be accumulated.

The preset second item may include content information registration and product purchase. The above example is only an example according to an embodiment and does not limit the scope of the present invention.

Here, the internet shopping mall or open market that sells the first product may be an affiliated company that allows the user to use the accumulated points.

In addition, after providing a purchase link for the first content, when a selection input for the external link is received from the second user terminal, the second user uses the desired amount of points to provide a discounted price. After enabling the purchase and transmitting the third notification, when the second user purchases the first product from the third user, the second user uses as many points as desired at a discounted price. You can have them purchase it.

As an optional embodiment, before providing the seller list, a seller list may be generated by randomly selecting a preset number of sellers from among other users selling the first product.

Specifically, the user who purchased the product may give a rating to the user who sold the product, and the user who sold the product may be given an average rating corresponding to the average of the ratings given by each user.

Next, when creating a seller list, the probability of being selected increases as the number of product sales, the higher the membership score, and the higher the average rating.

This has the effect of increasing the reliability of the seller list for users who purchase products by increasing the probability that users with high reliability in selling products will be selected.

Figure 10 is a diagram showing an example of a social network service according to an embodiment of the present invention.

Referring to Figure 10, the user can be connected to other users based on their tastes.
