+      Classifies input document into categories. Returns a list of categories
+      representing the document. Only the most relevant categories a document
+      are returned e.g. if  `/Science` and `/Science/Astronomy` both apply to a
+      document, then only the `/Science/Astronomy` category is returned, as it
+      is the more specific result.

+      Currently only English is supported for this feature.
