Previously I had been crawling the System for Electronic Disclosure by Insiders (“SEDI”) website exploring the data (here and here). Through some conversations I thought it would be interesting to create a social graph of all the data on this site where an “Insider” was an insider at 20 or more Canadian reporting issuers.
After crawling the data with Watir and Nokogiri infused Ruby script
, I fed the data into Gephi and then used SigmaJs to generate an interactive Social Graph of “Big” Insiders of Reporting Canadian Issuers. You’ll need a modern browser on a desktop or laptop with JavaScript enabled to interact with this graph
, otherwise you can pull down this static pdf summary: “Big” CDN SEDI Insiders.
The interactive Social Graph does an excellent job of illustrating the linkages between some of the “Insiders” and the underlying Issuers
, as well as the “distance” amongst others. Use your mouse to zoom in and have a look at the names, entities and linkages; an interesting Canadian perspective; enjoy!
