Embodiment Construction

[0064] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0065] The terms used in this application are defined as follows:

[0066] 1. The tag similarity between users and social activities: that is, the similarity between the user's interest tag set and the social activity attribute tag set.

[0067] 2. Geographic location preference: that is, the normalized probability value of the user's willingness to participate in the social activity when the user's current location and the place where the social activity is held are at a certain distance.

[0068] 3. The similarity between the user and the friends of the social event: that is, the similarity between the user's friend set and the set of currently registered participants of the social event.

[0069] 4. User preference value: that is, the user's preference value obtained by a content-based recommendation algorithm for a certain social activity...

Abstract

The invention discloses a social activity recommendation algorithm in a mobile social network, comprising the following steps: S1, calculating label similarity between any user and any social activity; S2, calculating geographical position preference degree between any user and any social activity; S3, calculating friend similarity between any user and any social activity; S4, calculating user preference of any user on any social activity; S5, calculating similarity between any user and any friend of the user; S6, calculating collaborative-filtering-based preference between any user and any social activity; S7, calculating preference scores of users on social activities; S8, recommending one social activity to a target user according to the preference scores of the target user on all the social activities. By adopting the social activity recommendation algorithm disclosed by the invention, the limitation of mechanized recommendation results caused by content-based recommendation is eliminated, so that the recommended social activity has more pertinence and accuracy.

Description

technical field [0001] The invention belongs to the technical field of data mining and user behavior analysis, and in particular relates to a social activity recommendation algorithm in a mobile social network. Background technique [0002] A mobile social network is a social network that is interconnected by multiple users with similar interests or common points through mobile terminals such as mobile phones or tablet computers. It combines the sociality of social networks and the mobility of mobile communication networks. Mobile communication system for social relations. However, these social network systems are mainly limited to individual users and their common points, such as common interests, same friends, etc., which cannot enable people to grab real social activity information and social resources. Thus, the concept of "mobile social network based on theme activities" was proposed. Mobile social networks based on themed activities are based on mobile devices and co...
