The Cognate extension creates a central store where the page titles for a group of sites are stored. It can then generate interwiki links across wiki projects in cases where the titles are the same. It was developed to solve the "Centralize interwiki language links for Wiktionary" task.

"Cognate" is a linguistic concept, referring to words in different languages developed from the same origin. This means that this extension is misnamed—since this extension links pages with the same title across wikis, a proper name would be “Homograph”.

ধারণা ও সীমাবদ্ধতা

  • Page titles are the same across languages (with some simple normalization applied).
  • Pages should not contain inter language links in wikitext as these will override the link provided by Cognate.
  • Unexpected hash conflicts are unlikely but could occur, and would result in unexpected language links.

এটি কীভাবে কাজ করে

Title Normalization

Very simple title normalization (reduction to ASCII) occurs within the extension. This can be seen in the StringNormalizer class.

Initially the amount of normalization is very small. Requests can be made to expand this and will be added on a case by case basis.

স্ট্রিং Normalized টীকা
Hello… Hello... The raw string contains an ellipsis character. This is normalized to three . characters
lepelle’ lepelle' The normalized string has a normalized apostrophe.

Title Hashing

Titles are hashed using sha256. This can be seen in the StringHasher class.

Part of the hash is then stored in the database in a BIG_INT field for efficient lookups.

There are roughly 18,446,744,073,709,551,615 possible values.

Matching Hashes

As titles that require links are assumed to be the same post normalization, they will result in the same hash and thus the same Int stored in the database.

Some sample data might look as follows when loading the "Foo..." page on enwiktionary.

উইকি শিরোনাম Hash Int Normalized Hash Int টীকা
enwiktionary Foo... 395730596998145766 395730596998145766 Matched row
frwiktionary Foo… -7435652355441782233 395730596998145766 Matched row, even though the pre normalized title includes the ellipsis character.

arwiktionary Foo 2071311921841431698 2071311921841431698

Overwriting

It is possible to overwrite the automatic links provided by Cognate, simply by adding one or more interwiki links in the page.

That also means that to make Cognate work when the extension is deployed, the pages should not contain inter language links in their wikitext.

ইনস্টল প্রক্রিয়া

  • ডাউনলোড করুন এবং আপনার extensions/ ফোল্ডারের Cognate নামক ডিরেক্টরিতে ফাইল(গুলি) নিন।
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Cognate
  • আপনার LocalSettings.php -এর নিচের অংশে নিম্নলিখিত কোড যোগ করুন: 
    wfLoadExtension( 'Cognate' );
# Settings used in WMF production
# Use the external cluster 'extension1' and dbname 'cognate_wiktionary'
$wgCognateDb = 'cognate_wiktionary';
$wgCognateCluster = 'extension1';
# Only work on the main namespace
$wgCognateNamespaces = [ 0 ];
