Librarians have used the Library of Congress Subject Headings (LCSH) for over 100 years to describe subject matter of the books, magazines, newspapers, maps, etc., in their collections.
When librarians automated their card catalogs in the 1980s, they also automated LCSH. That's when LCSH began to show its age.

making the most out of the small amount of subject information that LCSH provides to catalog users,
determining the extent to which everyday people understand subject headings, and
suggesting enhancements of LCSH and to the subject information that the catalog provides to its users.
