Method Detail

get

public static BrownClusters get()

This method should never be called before init, or the gazetteer will not be initialized.

Returns:

the singleton instance of the Gazetteers class.

set

public static void set(BrownClusters bc)

init

public static void init(Vector<String> pathsToClusterFiles,
                        Vector<Integer> thresholds,
                        Vector<Boolean> isLowercaseBrownClusters)

Parameters:

pathsToClusterFiles - the files containing the data.

thresholds -

isLowercaseBrownClusters -

Returns:

the resource names array.

getPrefixes
