MarkLogic Server includes a patented XML classifier which help organizations automatically classify their content to gain a better understanding of the content they have, to help refine search and to guide users to the content they are looking for. Classification can be useful even when an organization has a general idea about their content because it can help narrow the focus of understanding of topics covered within a corpus. Additionally it can also be used to quickly classify and understand new content which may have been acquired through partnership or purchase.
