For some editions of Wiktionary, extract translation pairs on each page.

ZIM is a file format that stores wiki content for offline usage.

• Wiktionary dumps in .zim format can be obtained from kiwix.

The input to this program can be either a .zim containing all pages of a Wiktionary edition, or a list of urls. See usage for more detail.

Each line consists of these fields:

• edition: the edition of Wiktionary the translation pair is from. It is a 2-3 letter code used in the Wiktionary url.
• headword: the word that is being translated.
• head_lang: the language of the headword. It might be different from the language of the edition.
• translation: the translation of the headword.
• trans_lang: the language the headword is translated into.
• trans_lang_code: the language code of trans_lang. This is the edition code used by Wiktionary, and it is not from a single ISO standard.
• pos: the part of speech of the headword in head_lang.
• pronunciation: the IPA representation of the headword; reflects how the word would be spoken in the head_lang

The output is in CSV format with these eight columns.

• beautifulsoup4: used for parsing html.
• requests: used to make http calls and fetch .html from the Internet. Required if using Internet as data source.
• pycountry and iso-639: used for conversion between language codes. Required if you do not specify an Wiktionary edition code.
• repoze.lru: LRU cache which significantly improve performance for .zim. Recommended if using .zim as data source.

Install in a virtualenv as appropriate. To install all dependencies (you don't have to):

$ pip install -r requirements.txt

To install one by one, use pip install [PACKAGE NAME].

parser.py or extract.py.

usage: parser.py [-h] (--url_zim URL_ZIM | --url_list URL_LIST | --zim ZIM)
                 [--edition EDITION]

optional arguments:
  -h, --help            show this help message and exit
  --url_zim URL_ZIM, -uz URL_ZIM
                        use a zim file as the source of urls and get html from
                        the Internet
  --url_list URL_LIST, -ul URL_LIST
                        use a file containing a list of urls and get html from
                        the Internet
  --zim ZIM, -z ZIM     use the zim file as input instead of html
  --edition EDITION, -e EDITION
                        explicitly specify the language edition, for either
                        html or zim

• Support for using .zim file has only been tested for Python 3.5. It is probably not working for Python 2 at this moment.
• parser.py should be able to automatically figure out the Wiktionary edition and choose the correct parser based on the url or the metadata in .zim. If it doens't use the parser you expect, please use -e to explicitly specify the edition.

A .zim file contains all pages in a Wiktionary edition.

To run parser.py with .zim as input:

$ python parser.py -z [ZIM FILE]

Instead of using a .zim file, you can also provide a list of urls to specify the pages to extract. The parser will fetch html from the urls to use as data source.

If you already have a file with a list of urls:

$ python parser.py -ul [FILE]

• The file should contain one url on each line.
• All urls should come from the same Wiktionary edition.

If you want to use the urls from a .zim file, which contains all the urls from a Wiktionary edition:

$ python parser.py -uz [ZIM FILE]

$ python -m zim.extract

-m is telling python to run a file in the module as main().

• Notice there is no .py extension.

$ python -m zim.extract -i ZIMFILE url

If you want full url:

$ python -m zim.extract -i ZIMFILE url -f

The edition will be inferred from metadata in .zim. If you want to explicitly specify the edition instead:

$ python -m zim.extract -i ZIMFILE url -f -e EDITION

$ python -m zim.extract -i ZIMFILE html -o OUTPUT_DIRECTORY

$ python -m parser.parse_[EDITION]

This is telling python to run the main() in a file in the module.

• Notice there is no .py extension.

• Tested with .zim file: ja, de
• Tested with some representative .html pages: az fr ru tr uz vi
• Started: pl

• Write parsers for two or three editions.
  • Run parsers on zim files (entire foreign editions of Wiktionary)
• Generalize them and create a skeleton for writing other parsers.
  • make it so that we need minimal changes in order to parse another edition
• Generate parsers for editions of interest.
• Modify current scripts to include pronunciation extraction from foreign editions of Wiktionary.
• Use translation scripts as base for derivation-table-parsing scripts.
