Duplicate chemical questions from https://chemistry.stackexchange.com/

Stackexchange is also a collection of questions, some of which have been marked as duplicates by site-adminsitrators. I downloaded a data dump that contains the questions sorted by subject. I picked the chemistry subject because MEsH includes many chemistry-related concepts. There are <strong>660</strong> questions that have been marked as <strong>duplicates (class 1).</strong> I generated a further <strong>861 pairs of non-duplicates (class 2) </strong>by looking for pairs of questions that aren't marked as either duplicates or related.
