BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments will be described in detail below with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The terms first, second, etc. may be used to describe various components, but the components are not limited by the terms, and the terms are used only for the purpose of distinguishing one component from another Is used.

First, in the prior art, when each user inputs a notification setting value such as a keyword of interest, it is searched whether or not the entire post is satisfied with the notification setting value set by each user, and a list of corresponding posts is transmitted to each user In the case of using the feedback method, many system resources may be consumed in order to search a large number of posts on the notification set values set by a plurality of users and notify each user of the result, and in particular, an online community such as SNS is activated According to the community, the number of subscribers and posts is explosively increasing. Therefore, it is not easy to operate efficiently, and in addition, a great amount of resources and costs may be consumed.

According to the present invention, after generating a list of subscribers for each notification setting set by the user, extracting the post information from the new posts and comparing the list with the list of subscribers for each notification setting to calculate a subscriber Discloses a method and system for notifying an online posting that a user can grasp a useful post among a large number of posts to be newly posted by a user in real time and can set an individual search environment suitable for the user through various settings for each user.

Hereinafter, exemplary embodiments of an online posting notification method and system according to the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 show an example of a notification setting screen according to an embodiment of the present invention and a new notification window screen for registered notification setting. As shown in FIG. 1, when a user inputs a predetermined keyword on the interest keyword setting screen, which is one of various notification settings that can be set by the user, when a post including the keyword of interest is newly registered in the community, As can be seen from FIG. 2, this can be quickly informed to the user by using a push alarm or the like, so that information required by the user can be obtained quickly, the two-way communication between the users can be smoothly performed, This enables online service providers to enjoy the benefits of improving business performance, such as advertising revenues.

At this time, in addition to setting a predetermined keyword by the user as described above, the author of the post or the bulletin board on which the bulletin is posted, the comment of the predetermined bulletin, the follow-up post is posted, It can also be configured to receive notifications when posted.

1, the user can set a plurality of keywords such as "Ralph Lauren" and "Polo ", or set the search range to" entire bulletin board " .

Also, as shown in FIG. 2, when a new post is registered, when a push method is used to inform the user, the user can be notified in real time that a post including the desired information is registered. However, the present invention is not limited to this, and it is also possible to use e-mail, SMS (Short Message Service), MMS (Multimedia Message Service) or the like.

FIG. 3 is a flowchart illustrating a method of notifying an online post according to an embodiment of the present invention. Here, a case where a user sets a post including a predetermined keyword of interest as a notification setting will be described as an example. As shown in FIG. 3, the method of notifying an online post according to an embodiment of the present invention includes inputting a keyword of interest through a terminal (S310), generating a subscriber list of interest keywords and a keyword index list of interest In operation S320, the user inputs a post through the terminal in operation S330. In operation S340, the post keyword is extracted from the post by comparing the title of the post with the index of interest index. Comparing the list of subscribers according to the keyword of interest, inquiring a subscriber for each keyword (S350), and transmitting a push notification message to the subscriber for each of the keywords (S360).

First, as shown in FIG. 1, in step S310, the user inputs a keyword of interest using a mobile terminal such as a smart phone or a PC. This step can be easily implemented and operated according to the prior art, and therefore will not be discussed in detail here.

Subsequently, in step S320 of generating a subscriber list and a keyword index list of interest by keyword, a list of subscribers for each keyword of interest and an index list of each keyword of interest are generated from the keywords of interest input by users. When the subscriber list and the keyword index list of the interest keyword are used, the keyword search operation for a plurality of posts and the subscriber calculation for each keyword can be performed very efficiently.

A setter for each of the interest keywords may be included in the list of subscribers for each interest keyword and a keyword for a plurality of posts is calculated by indexing and managing the interest keywords set by the user in the interest keyword index list It is possible to effectively calculate the post keywords by judging only whether or not the index includes the interested keyword.

As described above, in the related art, in order to search whether or not a specific keyword set by each user is included in a target of a specific keyword inputted by a user and send a list of posts containing the specific keyword to each user Significant time and resources are required. Especially, when a large community or a large number of posts are large, computing resources must be consumed, and it is more difficult to process many keywords set by a large number of users in real time. Furthermore, as online communities such as SNS have been activated in recent years, the number of subscribers and posts are increasing explosively depending on the community. In addition, there is an increasing demand for users to interact in real time through an online community such as SNS.

On the other hand, as described above, by using the list of subscribers for interest keywords and the list of interest keyword indexes, keyword search operations for a large number of posts and subscriber calculation for each keyword can be performed very efficiently.

In addition, it is also possible to effectively perform the task by limiting only the text portion of the post or searching only the title of the post to calculate a keyword and calculating a subscriber thereto. For example, the title of a normal post contains words that can express the contents of the post most strongly, whereas the length of the posts is usually very short. Therefore, by using these characteristics, It is possible to effectively calculate the result.

In addition, in generating or updating the subscriber list for each keyword of interest, it is possible to include a setter of a similar keyword for the keyword of interest as a subscriber. For example, you might include users who entered "iPhone" as a keyword of interest in the list of subscribers for the keyword of interest "iPhone".

Furthermore, in generating or updating the subscriber list of the interest keyword, a keyword of interest that does not exist in the subscriber may be generated. In this case, the computer resource can be efficiently operated by deleting the keyword item of interest.

Next, in step S330, the user inputs a predetermined post to a bulletin board of a community using a mobile terminal or a PC such as a smart phone. This step can be easily implemented and operated according to the prior art, and therefore will not be discussed in detail here.

Next, a step S340 of comparing the title of the post with the keyword index list of interest and extracting a post keyword for the post (S340) will be described. In this step, a post keyword is extracted for a predetermined post entered by the user in step S330. Here, as one embodiment of the present invention, a post keyword is extracted with respect to the title of the post. However, the present invention is not limited thereto, and the post keyword extraction operation may be limited to the entire or partial text portion of the post.

More specifically, if the title of the post is compared with the list of interest keyword indexes generated in advance and a keyword identical to the keyword of interest included in the keyword index list of interest exists in the title of the post, And extracted by a keyword. Accordingly, the number of words used in the search is limited to the number of words included in the keyword index list of interest, so that the post keyword extraction operation can be effectively performed.

Next, the subscriber list for each keyword is compared with the subscriber list for each keyword of interest (S350). In this step, the post keyword corresponding to the post extracted in step S340 is compared with the keywords of the subscriber list of the interest keyword generated in step S320, and subscribers corresponding to the respective post keywords are calculated. Conventionally, since a post is repeatedly searched using each keyword of interest set by each individual user and the search result is notified to each user, the consumption of the computing resource is large and it takes a lot of time In the present invention, subscriber information for each keyword can be easily retrieved from the list of subscribers for each keyword generated in advance, so that subscribers corresponding to each keyword can be calculated very efficiently.

At this time, when one interest keyword set by the user includes a plurality of words, it is possible to select a subscriber only when the plurality of words are included in the post keywords extracted from the posts.

Finally, in step S360 of transmitting a push notification message to the subscribers for each of the post keywords, a notice message is transmitted to each of the subscribers in a push manner, thereby notifying that a post including a post keyword is posted in real time. As described above, the push method should be used as an embodiment of the present invention, but the present invention is not necessarily limited to this. However, if the push method is used, registration information of a post can be delivered to each user in real time There are advantages.
