Problems solved by technology

Most of the existing information dissemination models and information maximization technologies are only aimed at the friendly relationship in the general social network, and are not connected with the specific reality. They just use the friendly relationship between users on the online social network. As long as it is activated, It will affect the surrounding friends, without considering whether the user will share with friends after being activated. If the user does not share, the information will not be spread

Embodiment

[0033] This method is mainly aimed at location-based social networks, mining the location information of users in it, modeling the information dissemination process, analyzing user behavior, and selecting an effective set of seed nodes so that information (specifically a piece of location information) passes through Online social networking is maximized to get the most users to the target location. This method mainly describes the process steps of modeling social network information dissemination, user behavior analysis, calculating influence to select the first seed node, and modifying influence to select all seed nodes. The data set in this embodiment is the location-based social network data set Brightkite provided by SNAP (Stanford Network Analysis Platform).

[0034] like figure 1As shown in , the description is given a target location information, the process of information dissemination through friendship in the social network. Model the dissemination process of infor...

Abstract

The invention discloses a location-based social contact data information maximizing method. According to the method, the social contact relations of a social network and the historical check-in data of each user are utilized; the degree of influence of the probability of user' willingness to share and the distances of the users on the behaviors of the users are mainly considered; the propagation process of information in the online social network is modeled; a method for selecting K seed nodes is provided; and the seed nodes and users influenced by the seed nodes influence the friends of the seed nodes and the users through friendship in the online social network, so that information propagation can be performed, and therefore, the number of influenced people can be maximum, namely, the maximization of information (target locations) can be realized.

Description

technical field [0001] The invention relates to a technology for researching the influence of social big data, in particular to a method for maximizing online social network information based on location information. Background technique [0002] With the development of the Internet and the popularization of mobile terminals, online social networks have gained rapid development and attention. The research on social network information maximization has very practical and practical significance.
