Abstract

In social sciences, the signed directed networks are used to represent the mutual friendship and foe attitudes among the members of a social group. Recent studies show that different real-world properties (e.g. preferential attachment, copying etc.) can be observed in the web-based social networks. In this thesis, we study the positive/negative - in/out - degree distributions in three online signed directed social networks. We observe that all signed-directed degree distributions in the web-based social networks with multiple edges possibilities (in both directions) follow a power law with exponents in the range 2.0
