This unique MarkLogic Semantics feature improves search and classification by identifying entities in free-flowing text. Use the feature to automatically identify entities (people, places, and things) in free-flowing text and then return a list of those entities (extraction) or mark them up in the document (enrichment).

Entities are defined in a user-maintained dictionary, or you can build a dictionary automatically from a SKOS Ontology. If you need NLP (Natural Language Processing) to define an entity, you can use third-party tools such as Smartlogic, PoolParty, Expert System, NetOwl, or Calais.

Review over the technical resources below to help get started.
