Abstract:
In this paper we report first results of our study on network
characteristics of a reference-based, bibliographically coupled (BC)
publication network structure. We find that this network of clustered
publications shows different statistical properties depending on the age of
the references used for building the network. A remarkable finding is that
only the network based on all references within publications is
characterized by a degree distribution with a power-law dependence. This
structure, which is typical for scale-free networks, disappears when
selecting references of a specific age for the clustering process. Changing
the publication network as a function of reference age, allows "tuning
through the episodic memory' of the nodes of the network. We find that the
older the references, the more the network tends to change its structure
towards a more exponential degree distribution.
