4CAT

Research tool to analyse and process data from online social platforms

The tool makes the capture and analysis of data from online social platforms accessible to people through a web interface, without requiring any programming or web scraping skills. In 4CAT, you create a dataset from a given platform according to a given set of parameters; the result of this (usually a CSV file containing matching items) can then be downloaded or analysed further with a suite of analytical "processors", which range from simple frequency charts to more advanced analyses such as the generation and visualisation of word embedding models. It currently support the following platforms: 4chan, 8kun, Bitchute, Parler, Reddit, Telegram, Twitter API.
