4CAT: Capture and Analysis Toolkit is a tool that can be used to scrape incoming posts on the imageboard 4chan and then process them for further analysis.
It allows one to query a corpus of 4chan posts selectively by keyword, date range or other criteria, and then output the results for further analysis. The tool was inspired by the TCAT
, a tool with comparable functionality that can be used to scrape and analyse Twitter data.
Currently, 4CAT can only be used when visiting it from a University of Amsterdam IP address. This means it is only available when browsing via eduroam at the University of Amsterdam, or using a University of Amsterdam VPN connection.
