Resumen:
Networks that exhibit large hubs are prone to showhigher connectivity than random structures. This feature is also reflected inthe presence of power law distribution in the degree distribution of nodes. Wecheck for the presence of power law degree distributions in Facebook Page Networks(FPN). We analyze data collected from 325 Facebook fan pages from anArgentinian median city summarizing 94 thousand nodes and 6.5 million edgesduring a whole year. We found that whole network exhibits power law degreedistributions but when we analyzed the subnetworks that compose it only ahandful of marginal networks in terms of size and level of engagement. We find thatmain subnetworks exhibit small world properties such as average geodesicdistance approximates and correlates to the natural logarithm of the graphrange. We begin our contribution by surveying the topic of power law in degreedistribution and small world in online networks. We estimate the slopes of thelog-log degree distribution for each network for identifying free scalestructures and statistically associate network structural properties with thepresence of power law distributions. We present statistical results thatassociate structural parameters with the presence of power law distributionsand small world effect shading light to new patterns for detecting theproperties in networks.
