| ⚫ | |||
This tool extracts main text from Wikipedia, producing a text corpus, which is useful for part of speech tagging, language model training, etc. |
|||
| ⚫ | |||
http://code.google.com/p/natural-language-qa/source/browse/MakeCorpus/WikiExtractor.py |
|||
==== usage ==== |
|||
1. Get the script. |
|||
http://code.google.com/p/natural-language-qa/source/browse/MakeCorpus/WikiExtractor.py |
|||
2. Download the Wikipedia dump file from http://dumps.wikimedia.org/backup-index.html |
|||
Let's Take Chinese as an example, download the file '''zhwiki-20130625-pages-articles.xml.bz2''' on this page http://dumps.wikimedia.org/zhwiki/20130625/ |
|||
Alternatively, we can download the latest version on this page, http://dumps.wikimedia.org/zhwiki/lastest/ |
|||
3. Use the script. |
|||
<pre> |
|||
mkdir output |
|||
bzcat zhwiki-20130625-pages-articles.xml.bz2 | ./WikiExtractor -o output |
|||
optionally, we can use "-c" for compression for saving disk space, and "-b" for setting specified bytes per output file. More information please type "./WikiExtractor --help". |
|||
</pre> |
|||
Ok, let's have a cup of tea and come back an hour later. |
|||
The output should be output/AA/wikiXX, where wikiXX are the extracted texts. |
|||
4. clean up "<>" tags |
|||
We are one step from the final text corpus, because there links in wikiXX files. Let's use the following tiny script to filter out "<>" tags. |
|||
<pre> |
|||
#! /usr/bin/python |
|||
# -*- coding:utf-8 -*- |
|||
import sys |
|||
import re |
|||
regex = re.compile(ur"<.*?>") |
|||
line = sys.stdin.readline() |
|||
while line != "": |
|||
line = regex.sub("", line)[ : -1] |
|||
print line |
|||
line = sys.stdin.readline() |
|||
</pre> |
|||
5. done :) |
