Data Preparation

Please use PyWxDump to extract WeChat chat records (WeChat version 4.0 is not supported). You can first migrate (or back up) your phone’s chat records to your computer to collect more data.

After downloading the software and decrypting the database:

• Click on Chat Backup

• Set the export format to CSV

• You can export multiple contacts (group chats are not recommended)

Then, place the exported CSV folder (located in wxdump_tmp/export/csv) into the ./dataset directory. In short, all folders of different users’ chat records should be placed together in ./dataset/csv.
