Mark Giaconia updated OPENNLP-579:
----------------------------------
Description:
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.
