Details of reference distribution and network statistics of the four primary association networks.

The table contains details of the first four primary association networks obtained by text-mining results using Agilent Literature search (ALS) plug in. ‘Total references’ refers to the total number of literature references used by the ALS plugin to generate the networks, ‘Unique references’ refer to the number of references that were used only once for the network generation while ‘Duplicate references’ refer to the number of references used more than once for network generation. ‘Network clustering coefficient’ is the average of the clustering coefficients for all nodes in the network and ‘average number of neighbors’ indicates the average connectivity of a node in the network.
