This is the dataset released with the paper titled: "Raiders of the Lost Kek: 3.5 Years of Augmented 4chan Posts from the Politically Incorrect Board".

The dataset is a single Newline delimited JSON file. Each line in the file consists of a JSON object which is a full 4chan /pol/ thread. The JSON objects contain all the key/values returned by the 4chan API, along with three additional keys (entities, perspectives, and extracted_poster_id).

For each JSON object we complement the data with the list of the named entities we detect for each post, using the spaCy Python library. In addition, for each post we add scores returned by the Google’s Perspective API, and more specifically seven scores in the [0; 1] interval.

For the detailed description of every key in the JSON structure, along with the type of the value, please read the readme.pdf file provided with this dataset.

How to extract the data:

Note that the data is compressed. See the instructions below on how to extract the data:

  • Linux and Mac

Step 1: Open a terminal window and navigate to the path where the file pol_0616-1119_labeled.tar.zst is located.

Step2: Run the following command:

unzstd pol_0616-1119_labeled.tar.zst

The above command will result in a file named pol_0616-1119_labeled.tar. (in the same directory)

Step 3: Again, from your terminal window, run this command:

tar -xvf pol_0616-1119_labeled.tar

When the above command finishes, you will get (in the same directory) the extracted data - a file named pol_062016-112019_labeled.ndjson.

  • Windows

There are many applications that can be used to extract this data on Windows available online. The authors cannot recommend specific applications. Note that the file is compressed twice so you will need to perform the data extraction twice - once on the downloaded file, and once on the file that was extracted from the downloaded file.
