Context

Data clean up

See also Convert files formats • Denoise files • Rename and mass rename

By default, we provide both per-language and all-lingualibre zip archives, which therefor double the data size of your download it all.

Find your target category

• Commons:Category:Lingua Libre pronunciation by user
• Commons:Category:Lingua Libre pronunciation by language

Tools

Python (current)

Dependencies: python.

Petscan and Wikiget allows to download about 15,000 audio files per hour.

1. Select your category : see Category:Lingua Libre pronunciation and Category:Lingua Libre pronunciation by user, then find your target category,
2. List target files with Petscan : Given a target category on Commons, provides list of target files. Example.
3. Download target files with Wikiget : downloads targets files.

Comments:

• Successful on November 2021, with 730,000 audio downloaded in 20 hours. Sustained average speed : 10 downloads/sec.
• Some delete files on Commons may cause Wikiget to return an error and pause. The script has to be resumed manually. Occurrence have been reported to be around 1/30,000 files. Fix is underway, support the request on github.
• WikiGet therefor requires a volunteer to supervise the script while running.

NodeJS (soon)

Dependencies: git, nodejs, npm.

A WikiapiJS script allows to download target category's files, or a root category, its subcategories and contained files. Downloads about 1,400 audio files per hour.

1. WikiapiJS is the NodeJS / NPM package allowing scripted API calls upon Wikimedia Commons and LinguaLibre.
2. Specific script used to do a given task:
   • Given a category, download all files : https://github.com/hugolpz/WikiapiJS-Eggs/blob/main/wiki-download-many.js
   • Given a root category, list subcategories, download all files: https://github.com/hugolpz/WikiapiJS-Eggs/blob/main/wiki-download_by_root_category-many.js

Comments, as of December 2021:

• Successful on December 2021, with 400 audios downloaded in 16 minutes. Sustained average speed : 0.4 downloads/sec.
• Successfully process single category's files.
• Successfully process root category and subcategories' files, generating ./isocode/ folders.
• Scalability tests for resilience with high amounts requests >500 to 100,000 items is required.
• Performance improvements are under consideration on github.

Python (slow)

Dependencies: python.

CommonsDownloadTool.py is a python script which formerly created datasets for LinguaLibre. It can be hacked and tinkered to your needs. To download all datasets as zips :

• Download scripts :
  • create_datasets.sh - creates CommonsDownloadTool's commands.
  • CommonsDownloadTool/commons_download_tool.py - core script.
• Read them a bit, move them where they fit the best on you computer so they require the minimum of editing
• Edit as needed so the paths are correct, make it work.
• Run create_datasets.sh
• Check if the number of files in the downloaded zips matches the number of files in Commons:Category:Lingua Libre pronunciation

Comments:

• This script is slow and has been phased out as Lingualibre grown too much.
• The page may gain from some html and styling.
• Proposals go on https://phabricator.wikimedia.org/tag/lingua_libre/ or on the LinguaLibre:Chat room.

Java (not tested)

Dependencies:

sudo apt-get install default-jre    # install Java environment

Usage:

• Open GitHub Wiki-java-tools project page.
• Find the last Imker release.
• Download Imker_vxx.xx.xx.zip archive
• Extract the .zip file
• Run as follow :
  • On Windows : start the .exe file.
  • On Ubuntu, open shell then :

$java -jar imker-cli.jar -o ./myFolder/ -c 'CategoryName'     # Downloads all medias within Wikimedia Commons's category "CategoryName"

Comments :

• Not used yet by any LinguaLibre member. If you do, please share your experience of this tool.

Javascript and/or API queries

See Help:APIs

There are also ways to use a category name as input, then to do API queries in order to get the list of files, download them. For a start point on API queries, see this pen, which gives some example of API queries.
