public class FeatureRule
extends GeocodeRule

NOT USED MUCH. Feature FeatureRule is a rule that makes use of feature distribution across the gazetteer as well as known properties of specific feature types that make them more or less likely to be the best location type for a particular mention. This may or may not be tie breakers -- within a feature class for the same name, this provides no tie breaker. "Boston", OH (P/PPL) ~ "Boston", MA (P/PPL) -- feature stats are the same. "Boston", ?? (T/ISL) ... is a different feature type and in this case is less likely to be the best location. Note -- other evidence and context has to overwhelm certain feature stats here. TODO: this overtakes the "DefaultScore" component from "scoreFeature()"

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
