wikidump

Framework for the extraction of features from Wikipedia XML dumps.

Installation

This project has been tested with Python >= 3.5, but we are targeting the newest releases of Python 3, so we don't promise backwards compatibility with earlier versions. In particular, we recomend to use Python >= 3.6.

If you find some bug on that front, open an issue.

You need to install dependencies first, as usual.

pip3 install -r requirements.txt

How it Works

You need to download Wikipedia dumps first, see the download.sh script. If you want a more complete set of scripts check out the wikidump-download-tools

The module needs to be executed with python3 -m, which basically runs the file __main__.py inside the module.

The module is structured in subcommands that run processors that accomplish a given task:

python3 -m wikidump FILE [FILE ...] {subcommand}

It will take some time, all extractors have been written trying to minimize RAM comsumption.

Usage

$ python3 -m wikidump -h
usage: wikidump [-h] [--output-dir OUTPUT_DIR] [--output-compression {7z,gzip,None,bz2}] [--dry-run]
                [FILE [FILE ...]] {extract-bibliography,extract-identifiers,extract-identifiers-history,extract-page-ids,extract-redirects,extract-revisionlist,count-sections,extract-wikilinks} ...

                        sub-commands help
    extract-bibliography
                        Extract only sections may be a bibliography

  --output-compression {7z,gzip,None,bz2}
                        Output compression format [default: None].
  --dry-run, -n         Don't write any file

Each subcommand has its own help message, watch out for required arguments:

$ python3 -m wikidump extract-bibliography -h
usage: wikidump [FILE [FILE ...]] extract-bibliography [-h] -l {de,sv,fr,ru,nl,en,it,es,pl} [--only-last-revision]

optional arguments:
  -h, --help            show this help message and exit
