Geographic aspects of tie strength and value of information in social networking

Relations between the dimension of social tie strength and the dimension of value of communicated information have been investigated in the past by researchers such as Mark Granovetter. Also the connection between spatial distance and the existence of ties in social networks with small world characteristics has been discussed by Liben-Nowell and others. In this contribution we aim at investigating the relation between the dimensions spatial distance and non-binary, continuous value of information. Furthermore, we discuss the connection between non-binary, continuous measures for value of information and the dimension of non-binary social, continuous measures of tie strength. We also especially investigate the interrelation between all three dimensions in Social Networking and especially the research question of whether a spatial dependency of the inverse relation between social tie strength and value of information exists which may be named 'Geo-Granovetter effect'. As a basis for our empirical investigations we used a large Twitter dataset, because this Social Medium allows us to simultaneously access spatial, social and informational dimensions of interaction and thus to simultaneously model these three dimensions for Social Networking. We found that the social tie strength decreases as expected with increasing spatial distance among participants in our data-set. We also observed that in general the information value decreases when the tie strength increases and that the value of information is independent from the distance. According to our findings, Social Media such as Twitter don't exhibit a Geo-Granovetter effect.
