Semantic Related Topics

When you get to the end of a topic, Discourse presents you with 5 suggestions of topics to read next. Nowadays, we pick 5 random topics for anonymous users and use the unread topics for logged-in users to populate that list, making it quick to generate but not very useful when you are researching a specific subject.

With the new Semantic Related Topics feature, we will use Semantic Textual Similarity between the current topic and all the other topics in your instance to suggest topics that are potentially more relevant to what a person is looking for.

This is enabled here on Meta for all, including anon

Semantic Search

This used the same logic we used for semantic related topics, but to power search results.
