Class ToMapUnicodeToAscii

java.lang.Object

gov.nih.nlm.nls.lvg.Flows.Transformation

gov.nih.nlm.nls.lvg.Flows.ToMapUnicodeToAscii

All Implemented Interfaces:

java.lang.Cloneable

public class ToMapUnicodeToAscii
extends Transformation
implements java.lang.Cloneable

This class converts Unicode characters to ASCII by table mapping. This is a pure table mapping method and is used to normalize unicode to ASCII for characrters can't be nroamlized by other algorithm.

Users may define their own mapping in $LVG/data/Unicode/unicodeMap.data.

Method Detail

Mutate

public static java.util.Vector<LexItem> Mutate(LexItem in,
                               java.util.Hashtable<java.lang.Character,java.lang.String> unicodeMap,
                               boolean detailsFlag,
                               boolean mutateFlag)

Performs the mutation of this flow component.

Parameters:

in - a LexItem as the input for this flow component

unicodeMap - a hash table contains the unicode mapping

detailsFlag - a boolean flag for processing details information

mutateFlag - a boolean flag for processing mutate information

Returns:

the results from this flow component - a collection (Vector) of LexItems

GetUnicodeMapFromFile

public static java.util.Hashtable<java.lang.Character,java.lang.String> GetUnicodeMapFromFile(Configuration config)

Read in unicode to ASCII mapping list from configuration file

Parameters:

config - Configuratin object

Returns:

a hash table of unicode to ASCII mapping list

MapUnicodeToAscii

public static java.lang.String MapUnicodeToAscii(char inChar,
                                 java.util.Hashtable<java.lang.Character,java.lang.String> unicodeMap)

Get unicode synonym

Parameters:

inChar - an input character

unicodeMap - a hash table contains the unicode

Returns:

the mapped unicode unicode string in ASCII

main

public static void main(java.lang.String[] args)

A unit test driver for this flow component.
