Interface IEntityLinker<T>

Namespace

NOpenNLP.Tools.Entitylinker

Assembly

NOpenNLP.Tools.dll

EntityLinkers establish connections to external data to enrich extracted entities. For instance, for Location entities a linker can be developed to lookup each found location in a geonames gazateer. Another example may be to find peoples' names and look them up in a database or active directory. Intended to return n best matches for any give search, but can also be implemented as deterministic.
