How does Stack Overflow find 'Linked' questions? Does it store a list of links somewhere in the DB? Or does it extract them from posts/comments dynamically?

  • I've noticed that short links are not recognized as 'linked' – Danubian Sailor May 28 '13 at 9:00
  • per my recent experience at Programmers, this feature was broken or changed few days ago. My "see also" / "related" / "dupe" comments that used to add questions in Linked section not long time ago, don't do that anymore – gnat May 28 '13 at 9:46

They are certainly stored in the database, and available in SEDE in the PostLinks table (for details, see the schema documentation).

When something happens to a question (like it's edited, or a comment is posted), the list of linked questions will be redetermined and stored in the database.
