Method Details

setCoordinates

public void setCoordinates(List<org.opensextant.data.Geocoding> geos)

addCoordinate

public void addCoordinate(org.opensextant.data.Geocoding geo)

addCoordinates

public void addCoordinates(List<org.opensextant.extraction.TextMatch> found)

reset

public void reset()

Description copied from class: GeocodeRule

no-op, unless overriden.

Overrides:

reset in class GeocodeRule

isRelevant

public boolean isRelevant()

Description copied from class: GeocodeRule

Override if rule instance has another view of relevance, e.g. coordinate rule: no coords found, so rule.isRelevant() is FALSE.

Overrides:

isRelevant in class GeocodeRule

Returns:

evaluate

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

If a particular geo is close to a candidate name/location, then add to the candidate's score for that location.

Specified by:

evaluate in class GeocodeRule

Parameters:

name - matched name in text

geo - gazetteer entry or location
