A method for evaluating the spatio-temporal linkage between real space activities and cyberspace behaviors

Abstract

The invention discloses a method for space-time linkage mechanism evaluation of real space activity and network space behaviors. The number of mobile phone users in an activity area during the activity period is calculated by utilizing mobile phone space-time track data; a real space activity radiometric force model is constructed by utilizing the mobile phone space-time track data and through identifying 'home' positions of the mobile phone users; according to social contact media data increase rules, an activity radiometric force model of network space is constructed by utilizing a logistic model; a comprehensive space-time radiometric force model of real space and the network space is constructed, to serve as a space-time linkage strength calculation basis; and space-time linkage strength between the real space and the network space is calculated by comparing space-time radiometric force and propagation velocity of activity in the real space, the network space and the real space - network space. According to the method, space-time linkage analysis between the real space activity and the network space behaviors in the message propagation process is added, and the whole process of propagation affecting by the activity can be presented more really.

Description

technical field [0001] The invention belongs to the technical field of information analysis, and relates to a time-space linkage analysis method of real space activities and cyberspace behaviors, in particular to a time-space linkage effect evaluation method of real space activities and cyberspace behaviors. [0002] technical background [0003] With the development of information and communication technology (ICT), mobile phones and mobile Internet are gradually becoming popular, which have a profound impact on human life. The impact of group activities in the real space spreads rapidly through the Internet in online cyberspace such as portal websites, Weibo, and WeChat. The spatio-temporal linkage analysis of real space activities and cyberspace behaviors is currently mainly based on the online and offline interactive public opinion propagation model based on the double-layer coupling network. The model constructs a directed scale-free network model for cyberspace behavio...
