Jax-dan/zhwiki-latest

This repository demonstrates access to the latest Chinese Wikipedia corpora.

Download

You can download the latest Chinese Wikipedia dump from the following link:

• Chinese Wikipedia Dump
• English Wikipedia Dump (For reference)

Extraction

After you download the dump, you can extract the data using the following commands:

# install wikiextractor
pip install wikiextractor

# extract the data
wikiextractor --json -o <output_dir> zhwiki-latest-pages-articles.xml.bz2

Then, you can find the extracted data in (such as) <output_dir>/AA/wiki_00

Convertion

You can convert the extracted data into a format that is more suitable for your needs using the following command:

# opencc
pip install pip install opencc-python

python wiki_parser.py --data_folder <input_folder> --format json

And the below is a demo of wiki_parser.py:

import json
import os
from os import path
from opencc import OpenCC

import argparse

from tqdm import tqdm
import pandas as pd
import shutil

# 繁体转简体（支持多种模式：t2s, s2twp等）
converter = OpenCC('t2s')
