This repository contains R code to build and plot 150 cosponsorship networks out of the legislative activity of 27 parliamentary chambers in 19 European countries, plus Israel. The data cover approximately 558 years of parliamentary interactions. The resulting networks are stored in parlnet.rda.
If you make use of the code or data made available through this repository, please cite the following paper:
Briatte, François. 2016. “Network Patterns of Legislative Collaboration in Twenty Parliaments.” Network Science, 4(2): 266–71. doi:10.1017/nws.2015.31
The paper is available online in preprint format, as well as its appendix, which explains how the data were collected and how the networks were constructed.
The repository contains a HOWTO file with detailed instructions on how to get and run the code, and the README file of each country-specific repository contains further details on code execution and data collection, as well as additional thanks to people who provided help. Further ideas and links are available in the repository wiki.
The raw data collected by release 2.6 (January 2016) is available online as an archive of HTML, JSON and XML files. It can be accessed at the following DOI handle:
Please report bugs or suggestions as issues, either in this repository if the issue affects all countries, or in the country-specific repository otherwise.
The code to produce interactive visualizations of the networks is available separately from the parlviz repository.
