Pruning of co-authorship networks from the 10<sup>th</sup> to 16<sup>th</sup> Philippine Congresses and the effect on the network properties
We implemented two pruning schemes, the percentile threshold by bill author count and by edge weights, on the co-authorship networks of through the 10th to 16th Philippine Congresses and determine the effect on the network measures. We found that connectivity is generally preserved in both implementations of the pruning methods. Also, in general, there is a peak in modularity found in the 1st - 20th percentile range in Congresses in both pruning schemes. It was also observed that pruning by bill author counts directly affects the network measures as smooth transitions are found in all plots while the pruning by edge weights contains saturation points caused by the long right tail of the edge distributions of the original networks.
