The Large Knowledge Base (LKB) gazetteer consists of a set of lists containing concepts (Persons, Locations, Organizations, etc.) loaded directly from the semantic repository you are going to use as a background knowledge, instead of predetermined and flat set of gazetteer lists. It means that certain annotated entities are linked to specific instances in the semantic repository. The LKB is part of the GATE distribution and provides efficient representation of very large vocabularies, as well as query-based selective loading from RDF databases.
The LKB makes use of a number of configuration files such as the set of SPARQL queries to be used on the ontology.
