wiktionary-de-parser 0.9.5

Extracts data from German Wiktionary dump files. Allows you to add your own extraction methods 🚀

wiktionary-de-parser

This is a Python module to extract data from German Wiktionary XML files (for Python 3.7+). It allows you to add your own extraction methods.

Installation

pip install wiktionary-de-parser

Features

• Extracts flexion tables, genus, IPA, language, lemma, part of speech (basic), syllables, raw Wikitext
• Allows you to add your own extraction methods (pass them as argument)
• Yields per section, not per page (a word can have multiple meanings --> multiple sections of a Wiktionary pages)

Usage

from bz2 import BZ2File
from wiktionary_de_parser import Parser

bzfile_path = '/tmp/dewiktionary-latest-pages-articles-multistream.xml.bz2'
bz_file = BZ2File(bzfile_path)

for record in Parser(bz_file):
    if 'lang_code' not in record or record['lang_code'] != 'de':
      continue
    # do stuff with 'record'

Note: In this example we load a compressed Wiktionary dump file that was obtained from here.

Adding new extraction methods

An extraction method takes the following arguments:

• title (string): The title of the current Wiktionary page
• text (string): The Wikitext of the current word entry/section
• current_record (Dict): A dictionary with all values of the current iteration (e. g. current_record['lang_code'])

It must return a Dict with the results or False if the record was processed unsuccesfully.

# Create a new extraction method
def my_method(title, text, current_record):
  # do stuff
  return {'my_field': my_data} if my_data else False

# Pass a list with all extraction methods to the class constructor:
for record in Parser(bz_file, custom_methods=[my_method]):
    print(record['my_field'])

Output

Example output for the word "Abend":

{'flexion': {'Akkusativ Plural': 'Abende',
             'Akkusativ Singular': 'Abend',
             'Dativ Plural': 'Abenden',

             'Genitiv Plural': 'Abende',
             'Genitiv Singular': 'Abends',
             'Genus': 'm',
             'Nominativ Plural': 'Abende',
             'Nominativ Singular': 'Abend'},
 'inflected': False,
 'ipa': ['ˈaːbn̩t', 'ˈaːbm̩t'],
 'lang': 'Deutsch',
 'lang_code': 'de',
 'lemma': 'Abend',
 'pos': {'Substantiv': []},
 'rhymes': ['aːbn̩t'],
