public static TestNumberModel testModel(String name)
                                 throws IOException

Throws:

IOException

trainModel

public static TrainSimilarityModel trainModel(String modelName)

getNumber

public NumberEnum getNumber(Context ec)

setExtents

public void setExtents(Context[] extentContexts)

Description copied from interface: TrainSimilarityModel

Creates simialrity training pairs based on the specified extents. Extents are considered compatible is they are in the same coreference chain, have the same named-entity tag, or share a common head word. Incompatible extents are chosen at random from the set of extents which don't meet this criteria.
