Problems solved by technology

Its modeling between users of EBSNs, between users and activities, between activities and organizers is not accurate enough, and it does not consider the influence of time elements on activity recommendation
[0007] The inventors found that in the prior art, the modeling of the social network is not accurate enough, and the feature analysis and utilization of the social network of the social network is not comprehensive enough in recommending activities for users of the social network

Abstract

The present invention is a multi-factor decision-making method for activity social network users to participate in activity recommendation. The steps are as follows: construct an activity-sponsor-user ESU graph model for the activity social network EBSN, and calculate the social influence generated by the activity on the user in the graph; Calculate the correlation between the activity and the activity content that the user has participated in; calculate the correlation between the activity and the activity location that the user has participated in; calculate the time correlation between the activity and the activity that the user has participated in; on the basis of the above four factors, use the classic J48 decision tree An algorithm decides whether a user will attend an event. The method of the present invention proposes to use activities and multiple factors of user's social influence, content correlation, location correlation and time correlation to predict whether a user will participate in an activity, reasonably utilizes the characteristics of the activity social network EBSN, and is suitable for the activity social network Event recommendation from EBSN.

Description

A multi-factor decision-making method for activity recommendation for social network users to participate in activities technical field The present invention relates to a kind of information mining technology, specifically, relate to a kind of activity social network user participates in activity Recommended multifactor decision-making method. Background technique [0002] In recent years, Event-based Social Networks (EBSNs for short) The attention of researchers is mainly because it provides a platform for users to organize, participate in and share social activities through online means, And users can also participate in real offline events, such as Meetup, Plancast, Facebook Event and Douban same city ​​and so on. With so many events on EBSNs at different times and locations, it takes a lot of time for users to find to activities that interest you. On EBSNs, activities can be automatically and accurately recommended to users, thereby allowing users to enrich the...
