Is There Preferential Attachment in the Growth of Early Semantic Noun Networks?

Recent research on the statistical structure of semantic networks has suggested that the structure of the adult lexicon reveals evidence of a learning mechanism involving preferential attachment. With preferential attachment, words entering the lexicon make connections to existing words in proportion to the connectedness of the existing words. We asked if preferential attachment—or other growth...

Emergence of Global Preferential Attachment From Local Interaction

Global degree/strength based preferential attachment is widely used as an evolution mechanism of networks. But it is hard to believe that any individual can get global information and shape the network architecture based on it. In this paper, it is found that the global preferential attachment emerges from the local interaction models, including distance-dependent preferential attachment (DDPA)...

Link Prediction in Complex Networks by Multi Degree Preferential-Attachment Indices

In principle, the rules of links formation of a network model can be considered as a kind of link prediction algorithm. By revisiting the preferential attachment mechanism for generating a scale-free network, here we propose a class of preferential attachment indices which are different from the previous one. Traditionally, the preferential attachment index is defined by the product of the rela...

Betweenness centrality as a driver of preferential attachment in the evolution of research collaboration networks

We analyze whether preferential attachment in scientific coauthorship networks is different for authors with different forms of centrality. Using a complete database for the scientific specialty of research about ―steel structures,‖ we show that betweenness centrality of an existing node is a significantly better predictor of preferential attachment by new entrants than degree or closeness cent...

The preferential attachment model∗

Many empirically studied networks have approximately so-called power-law or scale-free degree distributions. In Section 1 we formally define such distributions and explore some of their properties. We also introduce and briefly compare two methods for constructing random networks with approximately power-law degree distributions: generic scale-free networks and the preferential attachment model...
