PPT4J - Data

Download all files to get the dataset. Please check the MD5 checksums after download.

1. Run cat ppt4j_data.tar.xz.part* > ppt4j_data.tar.xz to get the complete archive.
2. Run awk '{print $2 " " $1}' MD5.txt > MD5.chk && md5sum --ignore-missing --check MD5.chk to check the integrity of downloaded files. The format of MD5.txt is not compatible with md5sum, so the awk command is employed to fix this. Sorry for the inconvenience.
3. Extract ppt4j_data.tar.xz, then follow the instructions at https://github.com/pan2013e/ppt4j. The tarball file is created in macOS with bsdtar, and you may notice warnings like tar: Ignoring unknown extended header keyword 'XXX' if you extract it in Linux with gnutar. You can just ignore these warnings, as long as the checksum is okay.
