> A framework for integrating/linking external data to named entities. For
> instance, geocoding or georeferencing location entities to geonames gazateers
> can be implemented as an EntityLinker. Initially created ticket to
> specifically solve the georeferencing/geolocating/geotagging problem, but the
> framework should allow linkage of any external data to any entity type.
> Commercial applications that do this are expensive, and there are many free
> gazateers one could use to create solutions with OpenNLP.
> UPDATE: The current implementation of the GeoEntityLinker uses Lucene to
> store the Gazateers, and provides utils for indexing them. The impl returns
> lat, long (and other gaz fields) for toponyms extracted with NER.
> All extracted toponyms are scored in four ways: fuzzy string matching,
> binning by location, context modeling, and country-mention proximity. These
> scores enable a good means of deciding what's worth keeping from the gaz.
