Every time you refresh this page, you might get two topics from two different curriculum documents, as aligned by the current model. An effort to find a close training pair is done, if effective, the pair is also shown, together with metadata about how the pair was annotated. A permalink at the bottom allows to retrieve the exact page for later archival, discussion and comparison. Refresh the pair for another pair.
