We study community structure in time-dependent legislation cosponsorship networks in the Peruvian Congress, and we compare them briefly to legislation cosponsorship networks in the US Senate. To study these legislatures, we employ a multilayer representation of temporal networks in which legislators in each layer are connected to each other with a weight that is based on how many bills they cosponsor. We then use multilayer modularity maximization to detect communities in these networks. From…

Legislative Networks

Legislatures are naturally interactive institutions. Creating laws, engaging in representation and oversight, and serving constituents are social processes. Legislators have many connections with…

How Brazilian congressmen connect: homophily and cohesion in voting and donation networks

This work investigates the Brazilian Congress to shed light on the relationships between the donations received by congressmen elected in 2014 and their voting behaviours during 2015 and 2016, and finds that partisan cohesion is strong and diverse in the voting network, while regional cohesion is consistently negligible.

Case studies in network community detection

This chapter presents via several case studies, community detection is not just an end unto itself, but rather a step in the analysis of network data, which is then useful for furthering research in the disciplinary domain of interest.

Optimizing state change detection in functional temporal networks through dynamic community detection

Analytical work suggesting that a uniform null network provides improved sensitivity to the detection of small evolving communities in temporal networks with positive edge weights bounded above by 1 is presented and a method for increasing the sensitivity of modularity maximization to state changes in nodal dynamics is proposed.

Disentangling Active and Passive Cosponsorship in the U.S. Congress

An Encoder+RGCN based model is developed that learns legislator representations from bill texts and speech transcripts that predict active and passive cosponsorship and shows that they are interpretable and generalize to unseen tasks.

Subsampling Spectral Clustering for Stochastic Block Models in Large-Scale Networks

A novel subsampling spectral clustering algorithm to identify community structures in large-scale networks with limited computing resources is proposed and can be realized even using a personal computer.

Using large-scale network analysis I map the cosponsorship networks of all 280,000 pieces of legislation proposed in the U.S. House and Senate from 1973 to 2004 and introduces a new measure called "connectedness" which uses information about the frequency of csponsorship and the number of cosponsors on each bill to make inferences about the social distance between legislators.
