public void reset()

Description copied from class: GeocodeRule

no-op, unless overriden.

Overrides:

reset in class GeocodeRule

evaluate

public void evaluate(PlaceCandidate name,
 org.opensextant.data.Place geo)

Description copied from class: GeocodeRule

The one evaluation scheme that all rules must implement. Given a single text match and a location, consider if the geo is a good geocoding for the match.

Specified by:

evaluate in class GeocodeRule

Parameters:

name - matched name in text

geo - gazetteer entry or location

evaluate

public void evaluate(List<PlaceCandidate> names)

Identify the distinct potential named places by location Group places by geohash bins at two levels geohash 3 and geohash 4. Give greater weight to those places in finer grained buckets. I.e., If the various named places in the document appear closer together, then it is likely those locations are the true ones so increment their score.

Overrides:

evaluate in class GeocodeRule

Parameters:

names - list of found place names
