Problems solved by technology

Although these studies have taken into account the impact of heterogeneous social relationships and the geographical location of activities on users, based on the group-event structure of the Meetup website, users must first join the group to participate in an activity
This feature makes the current research not fully applicable to the Meetup website

Embodiment Construction

[0075] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0076] The overall process of the present invention is as figure 1 As shown, the present invention starts from the user's own interest tags, combines the user's social relationship, and the geographical location where the activity occurs, recommends the activity that the user is interested in, obtains the authorization information on the Meetup website, and utilizes its open service interface Extract group data information, activity data information and member data information. For the extracted data set, the activity information that the user is interested in is extracted through preprocessing and a series of filtering techniques. The implementation steps of the preferred embodiment are:

[0077] Step 1) Divide the user's group into 35 major categories, and extract the data set information of the group according to these 35 categories:

Abstract

The invention discloses a method for recommending activities based on user interest and geographic location. Firstly, the corresponding permissions are obtained on the Meetup API open platform, and corresponding group data information and activity data information are extracted through the group interface, activity interface and member interface. and member data information; secondly, according to the extracted data set information, use the vector decomposition model to initially screen out the activity data sets that the user is interested in; then, combined with the user's social relationship, use the Pearson correlation coefficient to further screen out the user's interest Then, considering the influence of the geographic location where the activity occurs on whether the user participates in an activity, divide the geographic location where the activity occurs, and use an optimization method to determine the activity dataset that the user is ultimately interested in and participates in; finally, Successfully recommend event information to relevant users. The method of the invention can efficiently recommend suitable activities to users from massive activity data.

Description

technical field [0001] The invention relates to a method for recommending social activities to users, and belongs to the technical field of information networks. Background technique [0002] In 2004, Facebook was born in the United States, followed by the upsurge of social networking sites sweeping the world, and domestic SNS sites represented by Sina Weibo, Tencent Weibo, Renren, etc. have sprung up like mushrooms after rain.
