Web Tracker Co-occurrence Network
A Web tracking ecosystem dataset of 40,421,974 nodes and 140,613,762 edges, collected by KONECT via web crawl. Each record contains directed: False, weighted: False. Network of web trackers co-occurring on the same websites — useful for studying the tracking ecosystem and privacy implications.. Suitable for web tracking analysis, privacy research, network structure of advertising.
